Merge tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Media documentation is now split into admin-guide, driver-api and
   userspace-api books (a longstanding request from Jon);

 - The media Kconfig was reorganized, in order to make easier to select
   drivers and their dependencies;

 - The testing drivers now has a separate directory;

 - added a new driver for Rockchip Video Decoder IP;

 - The atomisp staging driver was resurrected. It is meant to work with
   4 generations of cameras on Atom-based laptops, tablets and cell
   phones. So, it seems worth investing time to cleanup this driver and
   making it in good shape.

 - Added some V4L2 core ancillary routines to help with h264 codecs;

 - Added an ov2740 image sensor driver;

 - The si2157 gained support for Analog TV, which, in turn, added
   support for some cx231xx and cx23885 boards to also support analog
   standards;

 - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
   V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
   is located at the device;

 - VIDIOC_ENUM_FMT was extended to support MC-centric devices;

 - Lots of drivers improvements and cleanups.

+======================================
+Avermedia DVB-T on BT878 Release Notes
+======================================
+
+February 14th 2006
+
+.. note::
+
+   Several other Avermedia devices are supported. For a more
+   broader and updated content about that, please check:
+
+   https://linuxtv.org/wiki/index.php/AVerMedia
+
+The Avermedia DVB-T
+~~~~~~~~~~~~~~~~~~~
+
+The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
+
+* RF Tuner Input
+* Composite Video Input (RCA Jack)
+* SVIDEO Input (Mini-DIN)
+
+The  RF  Tuner  Input  is the input to the tuner module of the
+card.  The  Tuner  is  otherwise known as the "Frontend" . The
+Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
+post  to  the  linux-dvb  mailing  list  ascertained  that the
+Microtune  7202D  is  supported  by the sp887x driver which is
+found in the dvb-hw CVS module.
+
+The  DVB-T card is based around the BT878 chip which is a very
+common multimedia bridge and often found on Analogue TV cards.
+There is no on-board MPEG2 decoder, which means that all MPEG2
+decoding  must  be done in software, or if you have one, on an
+MPEG2 hardware decoding card or chipset.
+
+
+Getting the card going
+~~~~~~~~~~~~~~~~~~~~~~
+
+At  this  stage,  it  has  not  been  able  to  ascertain  the
+functionality  of the remaining device nodes in respect of the
+Avermedia  DVBT.  However,  full  functionality  in respect of
+tuning,  receiving  and  supplying  the  MPEG2  data stream is
+possible  with the currently available versions of the driver.
+It  may be possible that additional functionality is available
+from  the  card  (i.e.  viewing the additional analogue inputs
+that  the card presents), but this has not been tested yet. If
+I get around to this, I'll update the document with whatever I
+find.
+
+To  power  up  the  card,  load  the  following modules in the
+following order:
+
+* modprobe bttv (normally loaded automatically)
+* modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
+
+Insertion  of  these  modules  into  the  running  kernel will
+activate the appropriate DVB device nodes. It is then possible
+to start accessing the card with utilities such as scan, tzap,
+dvbstream etc.
+
+The frontend module sp887x.o, requires an external   firmware.
+Please use  the  command "get_dvb_firmware sp887x" to download
+it. Then copy it to /usr/lib/hotplug/firmware or /lib/firmware/
+(depending on configuration of firmware hotplug).
+
+Known Limitations
+~~~~~~~~~~~~~~~~~
+
+At  present  I can say with confidence that the frontend tunes
+via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
+via   /dev/dvb/adapter{x}/dvr0.   I   have   not   tested  the
+functionality  of any other part of the card yet. I will do so
+over time and update this document.
+
+There  are some limitations in the i2c layer due to a returned
+error message inconsistency. Although this generates errors in
+dmesg  and  the  system logs, it does not appear to affect the
+ability of the frontend to function correctly.
+
+Further Update
+~~~~~~~~~~~~~~
+
+dvbstream  and  VideoLAN  Client on windows works a treat with
+DVB,  in  fact  this  is  currently  serving as my main way of
+viewing  DVB-T  at  the  moment.  Additionally, VLC is happily
+decoding  HDTV  signals,  although  the PC is dropping the odd
+frame here and there - I assume due to processing capability -
+as all the decoding is being done under windows in software.
+
+Many  thanks to Nigel Pearson for the updates to this document
+since the recent revision of the driver.

+How to get the bt8xx cards working
+==================================

+Authors:
+	 Richard Walker,
+	 Jamie Honan,
+	 Michael Hunold,
+	 Manu Abraham,
+	 Uwe Bugla,
+	 Michael Krufky
+
+General information
+-------------------
+
+This class of cards has a bt878a as the PCI interface, and require the bttv driver
+for accessing the i2c bus and the gpio pins of the bt8xx chipset.
+
+Please see :doc:`bttv-cardlist` for a complete list of Cards based on the
+Conexant Bt8xx PCI bridge supported by the Linux Kernel.
+
+In order to be able to compile the kernel, some config options should be
+enabled::
+
+    ./scripts/config -e PCI
+    ./scripts/config -e INPUT
+    ./scripts/config -m I2C
+    ./scripts/config -m MEDIA_SUPPORT
+    ./scripts/config -e MEDIA_PCI_SUPPORT
+    ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
+    ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
+    ./scripts/config -e MEDIA_RADIO_SUPPORT
+    ./scripts/config -e RC_CORE
+    ./scripts/config -m VIDEO_BT848
+    ./scripts/config -m DVB_BT8XX
+
+If you want to automatically support all possible variants of the Bt8xx
+cards, you should also do::
+
+    ./scripts/config -e MEDIA_SUBDRV_AUTOSELECT
+
+.. note::
+
+   Please use the following options with care as deselection of drivers which
+   are in fact necessary may result in DVB devices that cannot be tuned due
+   to lack of driver support.
+
+If your goal is to just support an specific board, you may, instead,
+disable MEDIA_SUBDRV_AUTOSELECT and manually select the frontend drivers
+required by your board. With that, you can save some RAM.
+
+You can do that by calling make xconfig/qconfig/menuconfig and look at
+the options on those menu options (only enabled if
+``Autoselect ancillary drivers`` is disabled:
+
+#) ``Device drivers`` => ``Multimedia support`` => ``Customize TV tuners``
+#) ``Device drivers`` => ``Multimedia support`` => ``Customize DVB frontends``
+
+Then, on each of the above menu, please select your card-specific
+frontend and tuner modules.
+
+
+Loading Modules
+---------------
+
+Regular case: If the bttv driver detects a bt8xx-based DVB card, all
+frontend and backend modules will be loaded automatically.
+
+Exceptions are:
+
+- Old TV cards without EEPROMs, sharing a common PCI subsystem ID;
+- Old TwinHan DST cards or clones with or without CA slot and not
+  containing an Eeprom.
+
+In the following cases overriding the PCI type detection for bttv and
+for dvb-bt8xx drivers by passing modprobe parameters may be necessary.
+
+Running TwinHan and Clones
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As shown at :doc:`bttv-cardlist`, TwinHan and
+clones use ``card=113`` modprobe parameter. So, in order to properly
+detect it for devices without EEPROM, you should use::
+
+	$ modprobe bttv card=113
+	$ modprobe dst
+
+Useful parameters for verbosity level and debugging the dst module::
+
+	verbose=0:		messages are disabled
+		1:		only error messages are displayed
+		2:		notifications are displayed
+		3:		other useful messages are displayed
+		4:		debug setting
+	dst_addons=0:		card is a free to air (FTA) card only
+		0x20:	card has a conditional access slot for scrambled channels
+	dst_algo=0:		(default) Software tuning algorithm
+	         1:		Hardware tuning algorithm
+
+
+The autodetected values are determined by the cards' "response string".
+
+In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
+
+For bug reports please send in a complete log with verbose=4 activated.
+Please also see :doc:`ci`.
+
+Running multiple cards
+~~~~~~~~~~~~~~~~~~~~~~
+
+See :doc:`bttv-cardlist` for a complete list of
+Card ID. Some examples:
+
+	===========================	===
+	Brand name			ID
+	===========================	===
+	Pinnacle PCTV Sat		 94
+	Nebula Electronics Digi TV	104
+	pcHDTV HD-2000 TV		112
+	Twinhan DST and clones		113
+	Avermedia AverTV DVB-T 77:	123
+	Avermedia AverTV DVB-T 761	124
+	DViCO FusionHDTV DVB-T Lite	128
+	DViCO FusionHDTV 5 Lite		135
+	===========================	===
+
+.. note::
+
+   When you have multiple cards, the order of the card ID should
+   match the order where they're detected by the system. Please notice
+   that removing/inserting other PCI cards may change the detection
+   order.
+
+Example::
+
+	$ modprobe bttv card=113 card=135
+
+In case of further problems please subscribe and send questions to
+the mailing list: linux-media@vger.kernel.org.
+
+Probing the cards with broken PCI subsystem ID
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are some TwinHan cards whose EEPROM has become corrupted for some
+reason. The cards do not have a correct PCI subsystem ID.
+Still, it is possible to force probing the cards with::
+
+	$ echo 109e 0878 $subvendor $subdevice > \
+		/sys/bus/pci/drivers/bt878/new_id
+
+The two numbers there are::
+
+	109e: PCI_VENDOR_ID_BROOKTREE
+	0878: PCI_DEVICE_ID_BROOKTREE_878

+
+Release notes for bttv
+----------------------
+
+You'll need at least these config options for bttv::
+
+    ./scripts/config -e PCI
+    ./scripts/config -m I2C
+    ./scripts/config -m INPUT
+    ./scripts/config -m MEDIA_SUPPORT
+    ./scripts/config -e MEDIA_PCI_SUPPORT
+    ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
+    ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
+    ./scripts/config -e MEDIA_RADIO_SUPPORT
+    ./scripts/config -e RC_CORE
+    ./scripts/config -m VIDEO_BT848
+
+If your board has digital TV, you'll also need::
+
+    ./scripts/config -m DVB_BT8XX
+
+In this case, please see :doc:`bt8xx` for additional notes.
+
+Make bttv work with your card
+-----------------------------
+
+If you have bttv compiled and installed, just booting the Kernel
+should be enough for it to try probing it. However, depending
+on the model, the Kernel may require additional information about
+the hardware, as the device may not be able to provide such info
+directly to the Kernel.
+
+If it doesn't bttv likely could not autodetect your card and needs some
+insmod options.  The most important insmod option for bttv is "card=n"
+to select the correct card type.  If you get video but no sound you've
+very likely specified the wrong (or no) card type.  A list of supported
+cards is in :doc:`bttv-cardlist`.
+
+If bttv takes very long to load (happens sometimes with the cheap
+cards which have no tuner), try adding this to your modules configuration
+file (usually, it is either ``/etc/modules.conf`` or some file at
+``/etc/modules-load.d/``, but the actual place depends on your
+distribution)::
+
+	options i2c-algo-bit bit_test=1
+
+Some cards may require an extra firmware file to work. For example,
+for the WinTV/PVR you need one firmware file from its driver CD,
+called: ``hcwamc.rbf``. It is inside a self-extracting zip file
+called ``pvr45xxx.exe``.  Just placing it at the ``/etc/firmware``
+directory should be enough for it to be autoload during the driver's
+probing mode (e. g. when the Kernel boots or when the driver is
+manually loaded via ``modprobe`` command).
+
+If your card isn't listed in :doc:`bttv-cardlist` or if you have
+trouble making audio work, please read :ref:`still_doesnt_work`.
+
+
+Autodetecting cards
+-------------------
+
+bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
+the Subsystem ID in the second line, looks like this:
+
+.. code-block:: none
+
+	00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
+		Subsystem: Hauppauge computer works Inc. WinTV/GO
+		Flags: bus master, medium devsel, latency 32, IRQ 5
+		Memory at e2000000 (32-bit, prefetchable) [size=4K]
+
+only bt878-based cards can have a subsystem ID (which does not mean
+that every card really has one).  bt848 cards can't have a Subsystem
+ID and therefore can't be autodetected.  There is a list with the ID's
+at :doc:`bttv-cardlist` (in case you are intrested or want to mail
+patches with updates).
+
+
+.. _still_doesnt_work:
+
+Still doesn't work?
+-------------------
+
+I do NOT have a lab with 30+ different grabber boards and a
+PAL/NTSC/SECAM test signal generator at home, so I often can't
+reproduce your problems.  This makes debugging very difficult for me.
+
+If you have some knowledge and spare time, please try to fix this
+yourself (patches very welcome of course...)  You know: The linux
+slogan is "Do it yourself".
+
+There is a mailing list at
+http://vger.kernel.org/vger-lists.html#linux-media
+
+If you have trouble with some specific TV card, try to ask there
+instead of mailing me directly.  The chance that someone with the
+same card listens there is much higher...
+
+For problems with sound:  There are a lot of different systems used
+for TV sound all over the world.  And there are also different chips
+which decode the audio signal.  Reports about sound problems ("stereo
+doesn't work") are pretty useless unless you include some details
+about your hardware and the TV sound scheme used in your country (or
+at least the country you are living in).
+
+Modprobe options
+----------------
+
+.. note::
+
+
+   The following argument list can be outdated, as we might add more
+   options if ever needed. In case of doubt, please check with
+   ``modinfo <module>``.
+
+   This command prints various information about a kernel
+   module, among them a complete and up-to-date list of insmod options.
+
+
+
+bttv
+	The bt848/878 (grabber chip) driver
+
+    insmod args::
+
+	    card=n		card type, see CARDLIST for a list.
+	    tuner=n		tuner type, see CARDLIST for a list.
+	    radio=0/1	card supports radio
+	    pll=0/1/2	pll settings
+
+			    0: don't use PLL
+			    1: 28 MHz crystal installed
+			    2: 35 MHz crystal installed
+
+	    triton1=0/1     for Triton1 (+others) compatibility
+	    vsfx=0/1	yet another chipset bug compatibility bit
+			    see README.quirks for details on these two.
+
+	    bigendian=n	Set the endianness of the gfx framebuffer.
+			    Default is native endian.
+	    fieldnr=0/1	Count fields.  Some TV descrambling software
+			    needs this, for others it only generates
+			    50 useless IRQs/sec.  default is 0 (off).
+	    autoload=0/1	autoload helper modules (tuner, audio).
+			    default is 1 (on).
+	    bttv_verbose=0/1/2  verbose level (at insmod time, while
+			    looking at the hardware).  default is 1.
+	    bttv_debug=0/1	debug messages (for capture).
+			    default is 0 (off).
+	    irq_debug=0/1	irq handler debug messages.
+			    default is 0 (off).
+	    gbuffers=2-32	number of capture buffers for mmap'ed capture.
+			    default is 4.
+	    gbufsize=	size of capture buffers. default and
+			    maximum value is 0x208000 (~2MB)
+	    no_overlay=0	Enable overlay on broken hardware.  There

+
+If the box freezes hard with bttv
+---------------------------------
+
+It might be a bttv driver bug.  It also might be bad hardware.  It also
+might be something else ...
+
+Just mailing me "bttv freezes" isn't going to help much.  This README
+has a few hints how you can help to pin down the problem.
+
+
+bttv bugs
+~~~~~~~~~
+
+If some version works and another doesn't it is likely to be a driver
+bug.  It is very helpful if you can tell where exactly it broke
+(i.e. the last working and the first broken version).
+
+With a hard freeze you probably doesn't find anything in the logfiles.
+The only way to capture any kernel messages is to hook up a serial
+console and let some terminal application log the messages.  /me uses
+screen.  See :doc:`/admin-guide/serial-console` for details on setting
+up a serial console.
+
+Read :doc:`/admin-guide/bug-hunting` to learn how to get any useful
+information out of a register+stack dump printed by the kernel on
+protection faults (so-called "kernel oops").
+
+If you run into some kind of deadlock, you can try to dump a call trace
+for each process using sysrq-t (see :doc:`/admin-guide/sysrq`).
+This way it is possible to figure where *exactly* some process in "D"
+state is stuck.
+
+I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
+for some people.  Thus probably a small buglet left somewhere in bttv
+0.7.x.  I have no idea where exactly, it works stable for me and a lot of
+other people.  But in case you have problems with the 0.7.x versions you
+can give 0.8.x a try ...
+
+
+hardware bugs
+~~~~~~~~~~~~~
+
+Some hardware can't deal with PCI-PCI transfers (i.e. grabber => vga).
+Sometimes problems show up with bttv just because of the high load on
+the PCI bus. The bt848/878 chips have a few workarounds for known
+incompatibilities, see README.quirks.
+
+Some folks report that increasing the pci latency helps too,
+althrought I'm not sure whenever this really fixes the problems or
+only makes it less likely to happen.  Both bttv and btaudio have a
+insmod option to set the PCI latency of the device.
+
+Some mainboard have problems to deal correctly with multiple devices
+doing DMA at the same time.  bttv + ide seems to cause this sometimes,
+if this is the case you likely see freezes only with video and hard disk
+access at the same time.  Updating the IDE driver to get the latest and
+greatest workarounds for hardware bugs might fix these problems.
+
+
+other
+~~~~~
+
+If you use some binary-only yunk (like nvidia module) try to reproduce
+the problem without.
+
+IRQ sharing is known to cause problems in some cases.  It works just
+fine in theory and many configurations.  Neverless it might be worth a
+try to shuffle around the PCI cards to give bttv another IRQ or make
+it share the IRQ with some other piece of hardware.  IRQ sharing with
+VGA cards seems to cause trouble sometimes.  I've also seen funny
+effects with bttv sharing the IRQ with the ACPI bridge (and
+apci-enabled kernel).
+
+Bttv quirks
+-----------
+
+Below is what the bt878 data book says about the PCI bug compatibility
+modes of the bt878 chip.
+
+The triton1 insmod option sets the EN_TBFX bit in the control register.
+The vsfx insmod option does the same for EN_VSFX bit.  If you have
+stability problems you can try if one of these options makes your box
+work solid.
+
+drivers/pci/quirks.c knows about these issues, this way these bits are
+enabled automagically for known-buggy chipsets (look at the kernel
+messages, bttv tells you).
+
+Normal PCI Mode
+~~~~~~~~~~~~~~~
+
+The PCI REQ signal is the logical-or of the incoming function requests.
+The inter-nal GNT[0:1] signals are gated asynchronously with GNT and
+demultiplexed by the audio request signal. Thus the arbiter defaults to
+the video function at power-up and parks there during no requests for
+bus access. This is desirable since the video will request the bus more
+often. However, the audio will have highest bus access priority. Thus
+the audio will have first access to the bus even when issuing a request
+after the video request but before the PCI external arbiter has granted
+access to the Bt879. Neither function can preempt the other once on the
+bus. The duration to empty the entire video PCI FIFO onto the PCI bus is
+very short compared to the bus access latency the audio PCI FIFO can
+tolerate.
+
+
+430FX Compatibility Mode
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using the 430FX PCI, the following rules will ensure
+compatibility:
+
+ (1) Deassert REQ at the same time as asserting FRAME.
+ (2) Do not reassert REQ to request another bus transaction until after
+     finish-ing the previous transaction.
+
+Since the individual bus masters do not have direct control of REQ, a
+simple logical-or of video and audio requests would violate the rules.
+Thus, both the arbiter and the initiator contain 430FX compatibility
+mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in
+Device Control Register on page 104.
+
+When EN_TBFX is enabled, the arbiter ensures that the two compatibility
+rules are satisfied. Before GNT is asserted by the PCI arbiter, this
+internal arbiter may still logical-or the two requests. However, once
+the GNT is issued, this arbiter must lock in its decision and now route
+only the granted request to the REQ pin. The arbiter decision lock
+happens regardless of the state of FRAME because it does not know when
+FRAME will be asserted (typically - each initiator will assert FRAME on
+the cycle following GNT). When FRAME is asserted, it is the initiator s
+responsibility to remove its request at the same time. It is the
+arbiters responsibility to allow this request to flow through to REQ and
+not allow the other request to hold REQ asserted. The decision lock may
+be removed at the end of the transaction: for example, when the bus is
+idle (FRAME and IRDY). The arbiter decision may then continue
+asynchronously until GNT is again asserted.
+
+
+Interfacing with Non-PCI 2.1 Compliant Core Logic
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A small percentage of core logic devices may start a bus transaction
+during the same cycle that GNT is de-asserted. This is non PCI 2.1
+compliant. To ensure compatibility when using PCs with these PCI
+controllers, the EN_VSFX bit must be enabled (refer to Device Control
+Register on page 104). When in this mode, the arbiter does not pass GNT
+to the internal functions unless REQ is asserted. This prevents a bus
+transaction from starting the same cycle as GNT is de-asserted. This
+also has the side effect of not being able to take advantage of bus
+parking, thus lowering arbitration performance. The Bt879 drivers must
+query for these non-compliant devices, and set the EN_VSFX bit only if
+required.
+
+
+Other elements of the tvcards array
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are trying to make a new card work you might find it useful to
+know what the other elements in the tvcards array are good for::
+
+	video_inputs    - # of video inputs the card has
+	audio_inputs    - historical cruft, not used any more.
+	tuner           - which input is the tuner
+	svhs            - which input is svhs (all others are labeled composite)
+	muxsel          - video mux, input->registervalue mapping
+	pll             - same as pll= insmod option
+	tuner_type      - same as tuner= insmod option
+	*_modulename    - hint whenever some card needs this or that audio
+			module loaded to work properly.
+	has_radio	- whenever this TV card has a radio tuner.
+	no_msp34xx	- "1" disables loading of msp3400.o module
+	no_tda9875	- "1" disables loading of tda9875.o module
+	needs_tvaudio	- set to "1" to load tvaudio.o module
+
+If some config item is specified both from the tvcards array and as
+insmod option, the insmod option takes precedence.

+
+This card is basically the same as all the rest (Bt484A, Philips tuner),
+the main difference is that they have attached a programmable attenuator to 3
+GPIO lines in order to give some volume control. They have also stuck an
+infra-red remote control decoded on the board, I will add support for this
+when I get time (it simple generates an interrupt for each key press, with
+the key code is placed in the GPIO port).
+
+I don't yet have any application to test the radio support. The tuner
+frequency setting should work but it is possible that the audio multiplexer
+is wrong. If it doesn't work, send me email.
+
+
+- No Thanks to Leadtek they refused to answer any questions about their
+  hardware. The driver was written by visual inspection of the card. If you
+  use this driver, send an email insult to them, and tell them you won't
+  continue buying their hardware unless they support Linux.
+
+- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw)
+  who make the audio attenuator. Their publicly available data-sheet available
+  on their web site doesn't include the chip programming information! Hidden
+  on their server are the full data-sheets, but don't ask how I found it.
+
+To use the driver I use the following options, the tuner and pll settings might
+be different in your country. You can force it via modprobe parameters.
+For example::
+
+    modprobe bttv  tuner=1 pll=28 radio=1 card=17
+
+Sets tuner type 1 (Philips PAL_I), PLL with a 28 MHz crystal, enables
+FM radio and selects bttv card ID 17 (Leadtek WinView 601).

+===================================
+Building support for a media device
+===================================
+
+The first step is to download the Kernel's source code, either via a
+distribution-specific source file or via the Kernel's main git tree\ [1]_.
+
+Please notice, however, that, if:
+
+- you're a braveheart and want to experiment with new stuff;
+- if you want to report a bug;
+- if you're developing new patches
+
+you should use the main media development tree ``master`` branch:
+
+    https://git.linuxtv.org/media_tree.git/
+
+In this case, you may find some useful information at the
+`LinuxTv wiki pages <https://linuxtv.org/wiki>`_:
+
+    https://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers
+
+.. [1] The upstream Linux Kernel development tree is located at
+
+       https://git.kernel.org/pub/scm/li  nux/kernel/git/torvalds/linux.git/
+
+Configuring the Linux Kernel
+============================
+
+You can access a menu of Kernel building options with::
+
+    $ make menuconfig
+
+Then, select all desired options and exit it, saving the configuration.
+
+The changed configuration will be at the ``.config`` file. It would
+look like::
+
+    ...
+    # CONFIG_RC_CORE is not set
+    # CONFIG_CEC_CORE is not set
+    CONFIG_MEDIA_SUPPORT=m
+    CONFIG_MEDIA_SUPPORT_FILTER=y
+    ...
+
+The media subsystem is controlled by those menu configuration options::
+
+    Device Drivers --->
+	<M> Remote Controller support  --->
+	[ ] HDMI CEC RC integration
+	[ ] Enable CEC error injection support
+	[*] HDMI CEC drivers  --->
+	<*> Multimedia support  --->
+
+The ``Remote Controller support`` option enables the core support for
+remote controllers\ [2]_.
+
+The ``HDMI CEC RC integration`` option enables integration of HDMI CEC
+with Linux, allowing to receive data via HDMI CEC as if it were produced
+by a remote controller directly connected to the machine.
+
+The ``HDMI CEC drivers`` option allow selecting platform and USB drivers
+that receives and/or transmits CEC codes via HDMI interfaces\ [3]_.
+
+The last option (``Multimedia support``) enables support for cameras,
+audio/video grabbers and TV.
+
+The media subsystem support can either be built together with the main
+Kernel or as a module. For most use cases, it is preferred to have it
+built as modules.
+
+.. note::
+
+   Instead of using a menu, the Kernel provides a script with allows
+   enabling configuration options directly. To enable media support
+   and remote controller support using Kernel modules, you could use::
+
+	$ scripts/config -m RC_CORE
+	$ scripts/config -m MEDIA_SUPPORT
+
+.. [2] ``Remote Controller support`` should also be enabled if you
+       want to use some TV card drivers that may depend on the remote
+       controller core support.
+
+.. [3] Please notice that the DRM subsystem also have drivers for GPUs
+       that use the media HDMI CEC support.
+
+       Those GPU-specific drivers are selected via the ``Graphics support``
+       menu, under ``Device Drivers``.
+
+       When a GPU driver supports supports HDMI CEC, it will automatically
+       enable the CEC core support at the media subsystem.
+
+Media dependencies
+------------------
+
+It should be noticed that enabling the above from a clean config is
+usually not enough. The media subsystem depends on several other Linux
+core support in order to work.
+
+For example, most media devices use a serial communication bus in
+order to talk with some peripherals. Such bus is called I²C
+(Inter-Integrated Circuit). In order to be able to build support
+for such hardware, the I²C bus support should be enabled, either via
+menu or with::
+
+    ./scripts/config -m I2C
+
+Another example: the remote controller core requires support for
+input devices, with can be enabled with::
+
+    ./scripts/config -m INPUT
+
+Other core functionality may also be needed (like PCI and/or USB support),
+depending on the specific driver(s) you would like to enable.
+
+Enabling Remote Controller Support
+----------------------------------
+
+The remote controller menu allows selecting drivers for specific devices.
+It's menu looks like this::
+
+         --- Remote Controller support
+         <M>   Compile Remote Controller keymap modules
+         [*]   LIRC user interface
+         [*]     Support for eBPF programs attached to lirc devices
+         [*]   Remote controller decoders  --->
+         [*]   Remote Controller devices  --->
+
+The ``Compile Remote Controller keymap modules`` option creates key maps for
+several popular remote controllers.
+
+The ``LIRC user interface`` option adds enhanced functionality when using the
+``lirc`` program, by enabling an API that allows userspace to receive raw data
+from remote controllers.
+
+The ``Support for eBPF programs attached to lirc devices`` option allows
+the usage of special programs (called eBPF) that would allow aplications
+to add extra remote controller decoding functionality to the Linux Kernel.
+
+The ``Remote controller decoders`` option allows selecting the
+protocols that will be recognized by the Linux Kernel. Except if you
+want to disable some specific decoder, it is suggested to keep all
+sub-options enabled.
+
+The ``Remote Controller devices`` allows you to select the drivers
+that would be needed to support your device.
+
+The same configuration can also be set via the ``script/config``
+script. So, for instance, in order to support the ITE remote controller
+driver (found on Intel NUCs and on some ASUS x86 desktops), you could do::
+
+	$ scripts/config -e INPUT
+	$ scripts/config -e ACPI
+	$ scripts/config -e MODULES
+	$ scripts/config -m RC_CORE
+	$ scripts/config -e RC_DEVICES
+	$ scripts/config -e RC_DECODERS
+	$ scripts/config -m IR_RC5_DECODER
+	$ scripts/config -m IR_ITE_CIR
+
+Enabling HDMI CEC Support
+-------------------------
+
+The HDMI CEC support is set automatically when a driver requires it. So,
+all you need to do is to enable support either for a graphics card
+that needs it or by one of the existing HDMI drivers.
+
+The HDMI-specific drivers are available at the ``HDMI CEC drivers``
+menu\ [4]_::
+
+	--- HDMI CEC drivers
+	< >   ChromeOS EC CEC driver
+	< >   Amlogic Meson AO CEC driver
+	< >   Amlogic Meson G12A AO CEC driver
+	< >   Generic GPIO-based CEC driver
+	< >   Samsung S5P CEC driver
+	< >   STMicroelectronics STiH4xx HDMI CEC driver
+	< >   STMicroelectronics STM32 HDMI CEC driver
+	< >   Tegra HDMI CEC driver
+	< >   SECO Boards HDMI CEC driver
+	[ ]     SECO Boards IR RC5 support
+	< >   Pulse Eight HDMI CEC
+	< >   RainShadow Tech HDMI CEC
+
+.. [4] The above contents is just an example. The actual options for
+       HDMI devices depends on the system's architecture and may vary
+       on new Kernels.
+
+Enabling Media Support
+----------------------
+
+The Media menu has a lot more options than the remote controller menu.
+Once selected, you should see the following options::
+
+	--- Media support
+	[ ] Filter media drivers
+	[*] Autoselect ancillary drivers
+	    Media device types --->
+	    Media core support --->
+	    Video4Linux options --->
+	    Media controller options --->
+	    Digital TV options --->
+	    HDMI CEC options --->
+	    Media drivers --->
+	    Media ancillary drivers --->
+
+Except if you know exactly what you're doing, or if you want to build
+a driver for a SoC platform, it is strongly recommended to keep the
+``Autoselect ancillary drivers`` option turned on, as it will auto-select
+the needed I²C ancillary drivers.
+
+There are now two ways to select media device drivers, as described
+below.
+
+``Filter media drivers`` menu
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This menu is meant to easy setup for PC and Laptop hardware. It works
+by letting the user to specify what kind of media drivers are desired,
+with those options::
+
+	[ ] Cameras and video grabbers
+	[ ] Analog TV
+	[ ] Digital TV
+	[ ] AM/FM radio receivers/transmitters
+	[ ] Software defined radio
+	[ ] Platform-specific devices
+	[ ] Test drivers
+
+So, if you want to add support to a camera or video grabber only,
+select just the first option. Multiple options are allowed.
+
+Once the options on this menu are selected, the building system will
+auto-select the needed core drivers in order to support the selected
+functionality.
+
+.. note::
+
+   Most TV cards are hybrid: they support both Analog TV and Digital TV.
+
+   If you have an hybrid card, you may need to enable both ``Analog TV``
+   and ``Digital TV`` at the menu.
+
+When using this option, the defaults for the the media support core
+functionality are usually good enough to provide the basic functionality
+for the driver. Yet, you could manually enable some desired extra (optional)
+functionality using the settings under each of the following
+``Media support`` sub-menus::
+
+	    Media core support --->
+	    Video4Linux options --->
+	    Media controller options --->
+	    Digital TV options --->
+	    HDMI CEC options --->
+
+Once you select the desired filters, the drivers that matches the filtering
+criteria will be available at the ``Media support->Media drivers`` sub-menu.
+
+``Media Core Support`` menu without filtering
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you disable the ``Filter media drivers`` menu, all drivers available
+for your system whose dependencies are met should be shown at the
+``Media drivers`` menu.
+
+Please notice, however, that you should first ensure that the
+``Media Core Support`` menu has all the core functionality your drivers
+would need, as otherwise the corresponding device drivers won't be shown.
+
+Example
+-------
+
+In order to enable modular support for one of the boards listed on
+:doc:`this table <cx231xx-cardlist>`, with modular media core modules, the
+``.config`` file should contain those lines::
+
+    CONFIG_MODULES=y
+    CONFIG_USB=y
+    CONFIG_I2C=y
+    CONFIG_INPUT=y
+    CONFIG_RC_CORE=m
+    CONFIG_MEDIA_SUPPORT=m
+    CONFIG_MEDIA_SUPPORT_FILTER=y
+    CONFIG_MEDIA_ANALOG_TV_SUPPORT=y
+    CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y
+    CONFIG_MEDIA_USB_SUPPORT=y
+    CONFIG_VIDEO_CX231XX=y
+    CONFIG_VIDEO_CX231XX_DVB=y
+
+Building and installing a new Kernel
+====================================
+
+Once the ``.config`` file has everything needed, all it takes to build
+is to run the ``make`` command::
+
+    $ make
+
+And then install the new Kernel and its modules::
+
+    $ sudo make modules_install
+    $ sudo make install
+
+Building just the new media drivers and core
+============================================
+
+Running a new development Kernel from the development tree is usually risky,
+because it may have experimental changes that may have bugs. So, there are
+some ways to build just the new drivers, using alternative trees.
+
+There is the `Linux Kernel backports project
+<https://backports.wiki.kernel.org/index.php/Main_Page>`_, with contains
+newer drivers meant to be compiled against stable Kernels.
+
+The LinuxTV developers, with are responsible for maintaining the media
+subsystem also maintains a backport tree, with just the media drivers
+daily updated from the newest kernel. Such tree is available at:
+
+https://git.linuxtv.org/media_build.git/
+
+It should be noticed that, while it should be relatively safe to use the
+``media_build`` tree for testing purposes, there are not warranties that
+it would work (or even build) on a random Kernel. This tree is maintained
+using a "best-efforts" principle, as time permits us to fix issues there.
+
+If you notice anything wrong on it, feel free to submit patches at the
+Linux media subsystem's mailing list: media@vger.kernel.org. Please
+add ``[PATCH media-build]`` at the e-mail's subject if you submit a new
+patch for the media-build.
+
+Before using it, you should run::
+
+    $ ./build
+
+.. note::
+
+    1) you may need to run it twice if the ``media-build`` tree gets
+       updated;
+    2) you may need to do a ``make distclean`` if you had built it
+       in the past for a different Kernel version than the one you're
+       currently using;
+    3) by default, it will use the same config options for media as
+       the ones defined on the Kernel you're running.
+
+In order to select different drivers or different config options,
+use::
+
+    $ make menuconfig
+
+Then, you can build and install the new drivers::
+
+    $ make && sudo make install
+
+This will override the previous media drivers that your Kernel were
+using.

+
+ca_zap
+~~~~~~
+
+A userspace application, like ``ca_zap`` is required to handle encrypted
+MPEG-TS streams.
+
+The ``ca_zap`` userland application is in charge of sending the
+descrambling related information to the Conditional Access Module (CAM).
+
+This application requires the following to function properly as of now.
+
+a) Tune to a valid channel, with szap.
+
+  eg: $ szap -c channels.conf -r "TMC" -x
+
+b) a channels.conf containing a valid PMT PID
+
+  eg: TMC:11996:h:0:27500:278:512:650:321
+
+  here 278 is a valid PMT PID. the rest of the values are the
+  same ones that szap uses.
+
+c) after running a szap, you have to run ca_zap, for the
+   descrambler to function,
+
+  eg: $ ca_zap channels.conf "TMC"
+
+d) Hopefully enjoy your favourite subscribed channel as you do with
+   a FTA card.
+
+.. note::
+
+  Currently ca_zap, and dst_test, both are meant for demonstration
+  purposes only, they can become full fledged applications if necessary.

+
+Cards that fall in this category
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At present the cards that fall in this category are the Twinhan and its
+clones, these cards are available as VVMER, Tomato, Hercules, Orange and
+so on.
+
+CI modules that are supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The CI module support is largely dependent upon the firmware on the cards
+Some cards do support almost all of the available CI modules. There is
+nothing much that can be done in order to make additional CI modules
+working with these cards.
+
+Modules that have been tested by this driver at present are
+
+(1) Irdeto 1 and 2 from SCM
+(2) Viaccess from SCM
+(3) Dragoncam

+The cpia2 driver
+================
+
+Authors: Peter Pregler <Peter_Pregler@email.com>,
+Scott J. Bertin <scottbertin@yahoo.com>, and
+Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
+this one was modelled from.
+
+Introduction
+------------
+
+This is a driver for STMicroelectronics's CPiA2 (second generation
+Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG
+stream at up to vga size. It implements the Video4Linux interface as much as
+possible.  Since the V4L interface does not support compressed formats, only
+an mjpeg enabled application can be used with the camera. We have modified the
+gqcam application to view this stream.
+
+The driver is implemented as two kernel modules. The cpia2 module
+contains the camera functions and the V4L interface.  The cpia2_usb module
+contains usb specific functions.  The main reason for this was the size of the
+module was getting out of hand, so I separated them.  It is not likely that
+there will be a parallel port version.
+
+Features
+--------
+
+- Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos
+  sensors. I only have the vga sensor, so can't test the other.
+- Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between.
+  VGA and QVGA are the native image sizes for the VGA camera. CIF is done
+  in the coprocessor by scaling QVGA.  All other sizes are done by clipping.
+- Palette: YCrCb, compressed with MJPEG.
+- Some compression parameters are settable.
+- Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA).
+- Adjust brightness, color, contrast while streaming.
+- Flicker control settable for 50 or 60 Hz mains frequency.
+
+Making and installing the stv672 driver modules
+-----------------------------------------------
+
+Requirements
+~~~~~~~~~~~~
+
+Video4Linux must be either compiled into the kernel or
+available as a module.  Video4Linux2 is automatically detected and made
+available at compile time.
+
+Setup
+~~~~~
+
+Use ``modprobe cpia2`` to load and ``modprobe -r cpia2`` to unload. This
+may be done automatically by your distribution.
+
+Driver options
+~~~~~~~~~~~~~~
+
+.. tabularcolumns:: |p{13ex}|L|
+
+
+==============  ========================================================
+Option		Description
+==============  ========================================================
+video_nr	video device to register (0=/dev/video0, etc)
+		range -1 to 64.  default is -1 (first available)
+		If you have more than 1 camera, this MUST be -1.
+buffer_size	Size for each frame buffer in bytes (default 68k)
+num_buffers	Number of frame buffers (1-32, default 3)
+alternate	USB Alternate (2-7, default 7)
+flicker_freq	Frequency for flicker reduction(50 or 60, default 60)
+flicker_mode	0 to disable, or 1 to enable flicker reduction.
+		(default 0). This is only effective if the camera
+		uses a stv0672 coprocessor.
+==============  ========================================================
+
+Setting the options
+~~~~~~~~~~~~~~~~~~~
+
+If you are using modules, edit /etc/modules.conf and add an options
+line like this::
+
+	options cpia2 num_buffers=3 buffer_size=65535
+
+If the driver is compiled into the kernel, at boot time specify them
+like this::
+
+	cpia2.num_buffers=3 cpia2.buffer_size=65535
+
+What buffer size should I use?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The maximum image size depends on the alternate you choose, and the
+frame rate achieved by the camera.  If the compression engine is able to
+keep up with the frame rate, the maximum image size is given by the table
+below.
+
+The compression engine starts out at maximum compression, and will
+increase image quality until it is close to the size in the table.  As long
+as the compression engine can keep up with the frame rate, after a short time
+the images will all be about the size in the table, regardless of resolution.
+
+At low alternate settings, the compression engine may not be able to
+compress the image enough and will reduce the frame rate by producing larger
+images.
+
+The default of 68k should be good for most users.  This will handle
+any alternate at frame rates down to 15fps.  For lower frame rates, it may
+be necessary to increase the buffer size to avoid having frames dropped due
+to insufficient space.
+

+
+Table: Image size(bytes)
+
+
+How many buffers should I use?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For normal streaming, 3 should give the best results.  With only 2,
+it is possible for the camera to finish sending one image just after a
+program has started reading the other.  If this happens, the driver must drop
+a frame.  The exception to this is if you have a heavily loaded machine.  In
+this case use 2 buffers.  You are probably not reading at the full frame rate.
+If the camera can send multiple images before a read finishes, it could
+overwrite the third buffer before the read finishes, leading to a corrupt
+image.  Single and double buffering have extra checks to avoid overwriting.
+
+Using the camera
+~~~~~~~~~~~~~~~~
+
+We are providing a modified gqcam application to view the output. In
+order to avoid confusion, here it is called mview.  There is also the qx5view
+program which can also control the lights on the qx5 microscope. MJPEG Tools
+(http://mjpeg.sourceforge.net) can also be used to record from the camera.

+The cx88 driver
+===============
+
+Author:  Gerd Hoffmann
+
+This is a v4l2 device driver for the cx2388x chip.
+
+
+Current status
+--------------
+
+video
+	- Works.
+	- Overlay isn't supported.
+
+audio
+	- Works. The TV standard detection is made by the driver, as the
+	  hardware has bugs to auto-detect.
+	- audio data dma (i.e. recording without loopback cable to the
+	  sound card) is supported via cx88-alsa.
+
+vbi
+	- Works.
+
+
+How to add support for new cards
+--------------------------------
+
+The driver needs some config info for the TV cards.  This stuff is in
+cx88-cards.c.  If the driver doesn't work well you likely need a new
+entry for your card in that file.  Check the kernel log (using dmesg)
+to see whenever the driver knows your card or not.  There is a line
+like this one:
+
+.. code-block:: none
+
+	cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
+		34xxx models [card=1,autodetected]
+
+If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
+the driver.  What to do then?
+
+1) Try upgrading to the latest snapshot, maybe it has been added
+   meanwhile.
+2) You can try to create a new entry yourself, have a look at
+   cx88-cards.c.  If that worked, mail me your changes as unified
+   diff ("diff -u").
+3) Or you can mail me the config information.  We need at least the
+   following information to add the card:
+
+     - the PCI Subsystem ID ("0070:3400" from the line above,
+       "lspci -v" output is fine too).
+     - the tuner type used by the card.  You can try to find one by
+       trial-and-error using the tuner=<n> insmod option.  If you
+       know which one the card has you can also have a look at the
+       list in CARDLIST.tuner

+
+The VPBE V4L2 driver design
+===========================
+
+Functional partitioning
+-----------------------
+
+Consists of the following:
+
+ 1. V4L2 display driver
+
+    Implements creation of video2 and video3 device nodes and
+    provides v4l2 device interface to manage VID0 and VID1 layers.
+
+ 2. Display controller
+
+    Loads up VENC, OSD and external encoders such as ths8200. It provides
+    a set of API calls to V4L2 drivers to set the output/standards
+    in the VENC or external sub devices. It also provides
+    a device object to access the services from OSD subdevice
+    using sub device ops. The connection of external encoders to VENC LCD
+    controller port is done at init time based on default output and standard
+    selection or at run time when application change the output through
+    V4L2 IOCTLs.
+
+    When connected to an external encoder, vpbe controller is also responsible
+    for setting up the interface between VENC and external encoders based on
+    board specific settings (specified in board-xxx-evm.c). This allows
+    interfacing external encoders such as ths8200. The setup_if_config()
+    is implemented for this as well as configure_venc() (part of the next patch)
+    API to set timings in VENC for a specific display resolution. As of this
+    patch series, the interconnection and enabling and setting of the external
+    encoders is not present, and would be a part of the next patch series.
+
+ 3. VENC subdevice module
+
+    Responsible for setting outputs provided through internal DACs and also
+    setting timings at LCD controller port when external encoders are connected
+    at the port or LCD panel timings required. When external encoder/LCD panel
+    is connected, the timings for a specific standard/preset is retrieved from
+    the board specific table and the values are used to set the timings in
+    venc using non-standard timing mode.
+
+    Support LCD Panel displays using the VENC. For example to support a Logic
+    PD display, it requires setting up the LCD controller port with a set of
+    timings for the resolution supported and setting the dot clock. So we could
+    add the available outputs as a board specific entry (i.e add the "LogicPD"
+    output name to board-xxx-evm.c). A table of timings for various LCDs
+    supported can be maintained in the board specific setup file to support
+    various LCD displays.As of this patch a basic driver is present, and this
+    support for external encoders and displays forms a part of the next
+    patch series.
+
+ 4. OSD module
+
+    OSD module implements all OSD layer management and hardware specific
+    features. The VPBE module interacts with the OSD for enabling and
+    disabling appropriate features of the OSD.
+
+Current status
+--------------
+
+A fully functional working version of the V4L2 driver is available. This
+driver has been tested with NTSC and PAL standards and buffer streaming.

+Using the Digital TV Framework
+==============================
+
+Introduction
+~~~~~~~~~~~~
+
+One significant difference between Digital TV and Analogue TV that the
+unwary (like myself) should consider is that, although the component
+structure of DVB-T cards are substantially similar to Analogue TV cards,
+they function in substantially different ways.
+
+The purpose of an Analogue TV is to receive and display an Analogue
+Television signal. An Analogue TV signal (otherwise known as composite
+video) is an analogue encoding of a sequence of image frames (25 frames
+per second in Europe) rasterised using an interlacing technique.
+Interlacing takes two fields to represent one frame. Therefore, an
+Analogue TV card for a PC has the following purpose:
+
+* Tune the receiver to receive a broadcast signal
+* demodulate the broadcast signal
+* demultiplex the analogue video signal and analogue audio
+  signal.
+
+  .. note::
+
+     some countries employ a digital audio signal
+     embedded within the modulated composite analogue signal -
+     using NICAM signaling.)
+
+* digitize the analogue video signal and make the resulting datastream
+  available to the data bus.
+
+The digital datastream from an Analogue TV card is generated by
+circuitry on the card and is often presented uncompressed. For a PAL TV
+signal encoded at a resolution of 768x576 24-bit color pixels over 25
+frames per second - a fair amount of data is generated and must be
+processed by the PC before it can be displayed on the video monitor
+screen. Some Analogue TV cards for PCs have onboard MPEG2 encoders which
+permit the raw digital data stream to be presented to the PC in an
+encoded and compressed form - similar to the form that is used in
+Digital TV.
+
+The purpose of a simple budget digital TV card (DVB-T,C or S) is to
+simply:
+
+* Tune the received to receive a broadcast signal. * Extract the encoded
+  digital datastream from the broadcast signal.
+* Make the encoded digital datastream (MPEG2) available to the data bus.
+
+The significant difference between the two is that the tuner on the
+analogue TV card spits out an Analogue signal, whereas the tuner on the
+digital TV card spits out a compressed encoded digital datastream. As
+the signal is already digitised, it is trivial to pass this datastream
+to the PC databus with minimal additional processing and then extract
+the digital video and audio datastreams passing them to the appropriate
+software or hardware for decoding and viewing.
+
+Getting the card going
+~~~~~~~~~~~~~~~~~~~~~~
+
+The Device Driver API for DVB under Linux will the following
+device nodes via the devfs filesystem:
+
+* /dev/dvb/adapter0/demux0
+* /dev/dvb/adapter0/dvr0
+* /dev/dvb/adapter0/frontend0
+
+The ``/dev/dvb/adapter0/dvr0`` device node is used to read the MPEG2
+Data Stream and the ``/dev/dvb/adapter0/frontend0`` device node is used
+to tune the frontend tuner module. The ``/dev/dvb/adapter0/demux0`` is
+used to control what programs will be received.
+
+Depending on the card's feature set, the Device Driver API could also
+expose other device nodes:
+
+* /dev/dvb/adapter0/ca0
+* /dev/dvb/adapter0/audio0
+* /dev/dvb/adapter0/net0
+* /dev/dvb/adapter0/osd0
+* /dev/dvb/adapter0/video0
+
+The ``/dev/dvb/adapter0/ca0`` is used to decode encrypted channels. The
+other device nodes are found only on devices that use the av7110
+driver, with is now obsoleted, together with the extra API whose such
+devices use.
+
+Receiving a digital TV channel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This section attempts to explain how it works and how this affects the
+configuration of a Digital TV card.
+
+On this example, we're considering tuning into DVB-T channels in
+Australia, at the Melbourne region.
+
+The frequencies broadcast by Mount Dandenong transmitters are,
+currently:
+
+Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
+
+===========	===========
+Broadcaster	Frequency
+===========	===========
+Seven		177.500 Mhz
+SBS		184.500 Mhz
+Nine		191.625 Mhz
+Ten		219.500 Mhz
+ABC		226.500 Mhz
+Channel 31	557.625 Mhz
+===========	===========
+
+The digital TV Scan utilities (like dvbv5-scan) have use a set of
+compiled-in defaults for various countries and regions. Those are
+currently provided as a separate package, called dtv-scan-tables. It's
+git tree is located at LinuxTV.org:
+
+    https://git.linuxtv.org/dtv-scan-tables.git/
+
+If none of the tables there suit, you can specify a data file on the
+command line which contains the transponder frequencies. Here is a
+sample file for the above channel transponders, in the old "channel"
+format::
+
+	# Data file for DVB scan program
+	#
+	# C Frequency SymbolRate FEC QAM
+	# S Frequency Polarisation SymbolRate FEC
+	# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
+
+	T 177500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+	T 184500000 7MHz AUTO AUTO QAM64 8k 1/8 NONE
+	T 191625000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+	T 219500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+	T 226500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+	T 557625000 7MHz AUTO AUTO QPSK 8k 1/16 NONE
+
+Nowadays, we prefer to use a newer format, with is more verbose and easier
+to understand. With the new format, the "Seven" channel transponder's
+data is represented by::
+
+	[Seven]
+		DELIVERY_SYSTEM = DVBT
+		FREQUENCY = 177500000
+		BANDWIDTH_HZ = 7000000
+		CODE_RATE_HP = AUTO
+		CODE_RATE_LP = AUTO
+		MODULATION = QAM/64
+		TRANSMISSION_MODE = 8K
+		GUARD_INTERVAL = 1/16
+		HIERARCHY = NONE
+		INVERSION = AUTO
+
+For an updated version of the complete table, please see:
+
+    https://git.linuxtv.org/dtv-scan-tables.git/tree/dvb-t/au-Melbourne
+
+When the Digital TV scanning utility runs, it will output a file
+containing the information for all the audio and video programs that
+exists into each channel's transponders which the card's frontend can
+lock onto. (i.e. any whose signal is strong enough at your antenna).
+
+Here's the output of the dvbv5 tools from a channel scan took from
+Melburne::

+FAQ
+===
+
+.. note::
+
+     1. With Digital TV, a single physical channel may have different
+	contents inside it. The specs call each one as a *service*.
+	This is what a TV user would call "channel". So, in order to
+	avoid confusion, we're calling *transponders* as the physical
+	channel on this FAQ, and *services* for the logical channel.
+     2. The LinuxTV community maintains some Wiki pages with contain
+        a lot of information related to the media subsystem. If you
+        don't find an answer for your needs here, it is likely that
+        you'll be able to get something useful there. It is hosted
+	at:
+
+	https://www.linuxtv.org/wiki/
+
+Some very frequently asked questions about Linux Digital TV support
+
+1. The signal seems to die a few seconds after tuning.
+
+	It's not a bug, it's a feature. Because the frontends have
+	significant power requirements (and hence get very hot), they
+	are powered down if they are unused (i.e. if the frontend device
+	is closed). The ``dvb-core`` module parameter ``dvb_shutdown_timeout``
+	allow you to change the timeout (default 5 seconds). Setting the
+	timeout to 0 disables the timeout feature.
+
+2. How can I watch TV?
+
+	Together with the Linux Kernel, the Digital TV developers support
+	some simple utilities which are mainly intended for testing
+	and to demonstrate how the DVB API works. This is called DVB v5
+	tools and are grouped together with the ``v4l-utils`` git repository:
+
+	    https://git.linuxtv.org/v4l-utils.git/
+
+	You can find more information at the LinuxTV wiki:
+
+	    https://www.linuxtv.org/wiki/index.php/DVBv5_Tools
+
+	The first step is to get a list of services that are transmitted.
+
+	This is done by using several existing tools. You can use
+	for example the ``dvbv5-scan`` tool. You can find more information
+	about it at:
+
+	    https://www.linuxtv.org/wiki/index.php/Dvbv5-scan
+
+	There are some other applications like ``w_scan`` [#]_ that do a
+	blind scan, trying hard to find all possible channels, but
+	those consumes a large amount of time to run.
+
+	.. [#] https://www.linuxtv.org/wiki/index.php/W_scan
+
+	Also, some applications like ``kaffeine`` have their own code
+	to scan for services. So, you don't need to use an external
+	application to obtain such list.
+
+	Most of such tools need a file containing a list of channel
+	transponders available on your area. So, LinuxTV developers
+	maintain tables of Digital TV channel transponders, receiving
+	patches from the community to keep them updated.
+
+	This list is hosted at:
+
+	    https://git.linuxtv.org/dtv-scan-tables.git
+
+	And packaged on several distributions.
+
+	Kaffeine has some blind scan support for some terrestrial standards.
+	It also relies on DTV scan tables, although it contains a copy
+	of it internally (and, if requested by the user, it will download
+	newer versions of it).
+
+	If you are lucky you can just use one of the supplied channel
+	transponders. If not, you may need to seek for such info at
+	the Internet and create a new file. There are several sites with
+	contains physical channel lists. For cable and satellite, usually
+	knowing how to tune into a single channel is enough for the
+	scanning tool to identify the other channels. On some places,
+	this could also work for terrestrial transmissions.
+
+	Once you have a transponders list, you need to generate a services
+	list with a tool like ``dvbv5-scan``.
+
+	Almost all modern Digital TV cards don't have built-in hardware
+	MPEG-decoders. So, it is up to the application to get a MPEG-TS
+	stream provided by the board, split it into audio, video and other
+	data and decode.
+
+3. Which Digital TV applications exist?
+
+	Several media player applications are capable of tuning into
+	digital TV channels, including Kaffeine, Vlc, mplayer and MythTV.
+
+	Kaffeine aims to be very user-friendly, and it is maintained
+	by one of the Kernel driver developers.
+
+	A comprehensive list of those and other apps can be found at:
+
+	    https://www.linuxtv.org/wiki/index.php/TV_Related_Software

+
+4. Can't get a signal tuned correctly
+
+	That could be due to a lot of problems. On my personal experience,
+	usually TV cards need stronger signals than TV sets, and are more
+	sensitive to noise. So, perhaps you just need a better antenna or
+	cabling. Yet, it could also be some hardware or driver issue.
+
+	For example, if you are using a Technotrend/Hauppauge DVB-C card
+	*without* analog module, you might have to use module parameter
+	adac=-1 (dvb-ttpci.o).
+
+	Please see the FAQ page at linuxtv.org, as it could contain some
+	valuable information:
+
+	    https://www.linuxtv.org/wiki/index.php/FAQ_%26_Troubleshooting
+
+	If that doesn't work, check at the linux-media ML archives, to
+	see if someone else had a similar problem with your hardware
+	and/or digital TV service provider:
+
+	    https://lore.kernel.org/linux-media/
+
+	If none of this works, you can try sending an e-mail to the
+	linux-media ML and see if someone else could shed some light.
+	The e-mail is linux-media AT vger.kernel.org.
+
+5. The dvb_net device doesn't give me any packets at all
+
+	Run ``tcpdump`` on the ``dvb0_0`` interface. This sets the interface
+	into promiscuous mode so it accepts any packets from the PID
+	you have configured with the ``dvbnet`` utility. Check if there
+	are any packets with the IP addr and MAC addr you have
+	configured with ``ifconfig`` or with ``ip addr``.
+
+	If ``tcpdump`` doesn't give you any output, check the statistics
+	which ``ifconfig`` or ``netstat -ni`` outputs. (Note: If the MAC
+	address is wrong, ``dvb_net`` won't get any input; thus you have to
+	run ``tcpdump`` before checking the statistics.) If there are no
+	packets at all then maybe the PID is wrong. If there are error packets,
+	then either the PID is wrong or the stream does not conform to
+	the MPE standard (EN 301 192, http://www.etsi.org/). You can
+	use e.g. ``dvbsnoop`` for debugging.
+
+6. The ``dvb_net`` device doesn't give me any multicast packets
+
+	Check your routes if they include the multicast address range.
+	Additionally make sure that "source validation by reversed path
+	lookup" is disabled::
+
+	  $ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"
+
+7. What are all those modules that need to be loaded?
+
+	In order to make it more flexible and support different hardware
+	combinations, the media subsystem is written on a modular way.
+
+	So, besides the Digital TV hardware module for the main chipset,
+	it also needs to load a frontend driver, plus the Digital TV
+	core. If the board also has remote controller, it will also
+	need the remote controller core and the remote controller tables.
+	The same happens if the board has support for analog TV: the
+	core support for video4linux need to be loaded.
+
+	The actual module names are Linux-kernel version specific, as,
+	from time to time, things change, in order to make the media
+	support more flexible.

+The Samsung S5P/EXYNOS4 FIMC driver
+===================================
+
+Copyright |copy| 2012 - 2013 Samsung Electronics Co., Ltd.
+
+The FIMC (Fully Interactive Mobile Camera) device available in Samsung
+SoC Application Processors is an integrated camera host interface, color
+space converter, image resizer and rotator.  It's also capable of capturing
+data from LCD controller (FIMD) through the SoC internal writeback data
+path.  There are multiple FIMC instances in the SoCs (up to 4), having
+slightly different capabilities, like pixel alignment constraints, rotator
+availability, LCD writeback support, etc. The driver is located at
+drivers/media/platform/exynos4-is directory.
+
+Supported SoCs
+--------------
+
+S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
+
+Supported features
+------------------
+
+- camera parallel interface capture (ITU-R.BT601/565);
+- camera serial interface capture (MIPI-CSI2);
+- memory-to-memory processing (color space conversion, scaling, mirror
+  and rotation);
+- dynamic pipeline re-configuration at runtime (re-attachment of any FIMC
+  instance to any parallel video input or any MIPI-CSI front-end);
+- runtime PM and system wide suspend/resume
+
+Not currently supported
+-----------------------
+
+- LCD writeback input
+- per frame clock gating (mem-to-mem)
+
+User space interfaces
+---------------------
+
+Media device interface
+~~~~~~~~~~~~~~~~~~~~~~
+
+The driver supports Media Controller API as defined at :ref:`media_controller`.
+The media device driver name is "SAMSUNG S5P FIMC".
+
+The purpose of this interface is to allow changing assignment of FIMC instances
+to the SoC peripheral camera input at runtime and optionally to control internal
+connections of the MIPI-CSIS device(s) to the FIMC entities.
+
+The media device interface allows to configure the SoC for capturing image
+data from the sensor through more than one FIMC instance (e.g. for simultaneous
+viewfinder and still capture setup).
+
+Reconfiguration is done by enabling/disabling media links created by the driver
+during initialization. The internal device topology can be easily discovered
+through media entity and links enumeration.
+
+Memory-to-memory video node
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+V4L2 memory-to-memory interface at /dev/video? device node.  This is standalone
+video device, it has no media pads. However please note the mem-to-mem and
+capture video node operation on same FIMC instance is not allowed.  The driver
+detects such cases but the applications should prevent them to avoid an
+undefined behaviour.
+
+Capture video node
+~~~~~~~~~~~~~~~~~~
+
+The driver supports V4L2 Video Capture Interface as defined at
+:ref:`devices`.
+
+At the capture and mem-to-mem video nodes only the multi-planar API is
+supported. For more details see: :ref:`planar-apis`.
+
+Camera capture subdevs
+~~~~~~~~~~~~~~~~~~~~~~
+
+Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
+node is also created per each available and enabled at the platform level
+MIPI-CSI receiver device (currently up to two).
+
+sysfs
+~~~~~
+
+In order to enable more precise camera pipeline control through the sub-device
+API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
+device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
+
+In typical use case there could be a following capture pipeline configuration:
+sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
+
+When we configure these devices through sub-device API at user space, the
+configuration flow must be from left to right, and the video node is
+configured as last one.
+
+When we don't use sub-device user space API the whole configuration of all
+devices belonging to the pipeline is done at the video node driver.
+The sysfs entry allows to instruct the capture node driver not to configure
+the sub-devices (format, crop), to avoid resetting the subdevs' configuration
+when the last configuration steps at the video node is performed.
+
+For full sub-device control support (subdevs configured at user space before
+starting streaming):
+
+.. code-block:: none
+
+	# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+
+For V4L2 video node control only (subdevs configured internally by the host
+driver):
+
+.. code-block:: none
+
+	# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+
+This is a default option.
+
+5. Device mapping to video and subdev device nodes
+--------------------------------------------------
+
+There are associated two video device nodes with each device instance in
+hardware - video capture and mem-to-mem and additionally a subdev node for
+more precise FIMC capture subsystem control. In addition a separate v4l2
+sub-device node is created per each MIPI-CSIS device.
+
+How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which
+device?
+
+You can either grep through the kernel log to find relevant information, i.e.
+
+.. code-block:: none
+
+	# dmesg | grep -i fimc
+
+(note that udev, if present, might still have rearranged the video nodes),
+
+or retrieve the information from /dev/media? with help of the media-ctl tool:
+
+.. code-block:: none
+
+	# media-ctl -p
+
+7. Build

+If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
+two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
+optional s5p-csis.ko (MIPI-CSI receiver subdev).

+I²C drivers
+===========
+
+The I²C (Inter-Integrated Circuit) bus is a three-wires bus used internally
+at the media cards for communication between different chips. While the bus
+is not visible to the Linux Kernel, drivers need to send and receive
+commands via the bus. The Linux Kernel driver abstraction has support to
+implement different drivers for each component inside an I²C bus, as if
+the bus were visible to the main system board.
+
+One of the problems with I²C devices is that sometimes the same device may
+work with different I²C hardware. This is common, for example, on devices
+that comes with a tuner for North America market, and another one for
+Europe. Some drivers have a ``tuner=`` modprobe parameter to allow using a
+different tuner number in order to address such issue.
+
+The current supported of I²C drivers (not including staging drivers) are
+listed below.

+i.MX Video Capture Driver
+=========================
+
+Introduction
+------------
+
+The Freescale i.MX5/6 contains an Image Processing Unit (IPU), which
+handles the flow of image frames to and from capture devices and
+display devices.
+
+For image capture, the IPU contains the following internal subunits:
+
+- Image DMA Controller (IDMAC)
+- Camera Serial Interface (CSI)
+- Image Converter (IC)
+- Sensor Multi-FIFO Controller (SMFC)
+- Image Rotator (IRT)
+- Video De-Interlacing or Combining Block (VDIC)
+
+The IDMAC is the DMA controller for transfer of image frames to and from
+memory. Various dedicated DMA channels exist for both video capture and
+display paths. During transfer, the IDMAC is also capable of vertical
+image flip, 8x8 block transfer (see IRT description), pixel component
+re-ordering (for example UYVY to YUYV) within the same colorspace, and
+packed <--> planar conversion. The IDMAC can also perform a simple
+de-interlacing by interweaving even and odd lines during transfer
+(without motion compensation which requires the VDIC).
+
+The CSI is the backend capture unit that interfaces directly with
+camera sensors over Parallel, BT.656/1120, and MIPI CSI-2 buses.
+
+The IC handles color-space conversion, resizing (downscaling and
+upscaling), horizontal flip, and 90/270 degree rotation operations.
+
+There are three independent "tasks" within the IC that can carry out
+conversions concurrently: pre-process encoding, pre-process viewfinder,
+and post-processing. Within each task, conversions are split into three
+sections: downsizing section, main section (upsizing, flip, colorspace
+conversion, and graphics plane combining), and rotation section.
+
+The IPU time-shares the IC task operations. The time-slice granularity
+is one burst of eight pixels in the downsizing section, one image line
+in the main processing section, one image frame in the rotation section.
+
+The SMFC is composed of four independent FIFOs that each can transfer
+captured frames from sensors directly to memory concurrently via four
+IDMAC channels.
+
+The IRT carries out 90 and 270 degree image rotation operations. The
+rotation operation is carried out on 8x8 pixel blocks at a time. This
+operation is supported by the IDMAC which handles the 8x8 block transfer
+along with block reordering, in coordination with vertical flip.
+
+The VDIC handles the conversion of interlaced video to progressive, with
+support for different motion compensation modes (low, medium, and high
+motion). The deinterlaced output frames from the VDIC can be sent to the
+IC pre-process viewfinder task for further conversions. The VDIC also
+contains a Combiner that combines two image planes, with alpha blending
+and color keying.
+
+In addition to the IPU internal subunits, there are also two units
+outside the IPU that are also involved in video capture on i.MX:
+
+- MIPI CSI-2 Receiver for camera sensors with the MIPI CSI-2 bus
+  interface. This is a Synopsys DesignWare core.
+- Two video multiplexers for selecting among multiple sensor inputs
+  to send to a CSI.
+
+For more info, refer to the latest versions of the i.MX5/6 reference
+manuals [#f1]_ and [#f2]_.
+
+
+Features
+--------
+
+Some of the features of this driver include:
+
+- Many different pipelines can be configured via media controller API,
+  that correspond to the hardware video capture pipelines supported in
+  the i.MX.
+
+- Supports parallel, BT.565, and MIPI CSI-2 interfaces.
+
+- Concurrent independent streams, by configuring pipelines to multiple
+  video capture interfaces using independent entities.
+
+- Scaling, color-space conversion, horizontal and vertical flip, and
+  image rotation via IC task subdevs.
+
+- Many pixel formats supported (RGB, packed and planar YUV, partial
+  planar YUV).
+
+- The VDIC subdev supports motion compensated de-interlacing, with three
+  motion compensation modes: low, medium, and high motion. Pipelines are
+  defined that allow sending frames to the VDIC subdev directly from the
+  CSI. There is also support in the future for sending frames to the
+  VDIC from memory buffers via a output/mem2mem devices.
+
+- Includes a Frame Interval Monitor (FIM) that can correct vertical sync
+  problems with the ADV718x video decoders.
+
+
+Topology
+--------
+
+The following shows the media topologies for the i.MX6Q SabreSD and
+i.MX6Q SabreAuto. Refer to these diagrams in the entity descriptions
+in the next section.
+
+The i.MX5/6 topologies can differ upstream from the IPUv3 CSI video
+multiplexers, but the internal IPUv3 topology downstream from there
+is common to all i.MX5/6 platforms. For example, the SabreSD, with the
+MIPI CSI-2 OV5640 sensor, requires the i.MX6 MIPI CSI-2 receiver. But
+the SabreAuto has only the ADV7180 decoder on a parallel bt.656 bus, and
+therefore does not require the MIPI CSI-2 receiver, so it is missing in
+its graph.

+
+Entities
+--------
+
+imx6-mipi-csi2
+--------------
+
+This is the MIPI CSI-2 receiver entity. It has one sink pad to receive
+the MIPI CSI-2 stream (usually from a MIPI CSI-2 camera sensor). It has
+four source pads, corresponding to the four MIPI CSI-2 demuxed virtual
+channel outputs. Multiple source pads can be enabled to independently
+stream from multiple virtual channels.
+
+This entity actually consists of two sub-blocks. One is the MIPI CSI-2
+core. This is a Synopsys Designware MIPI CSI-2 core. The other sub-block
+is a "CSI-2 to IPU gasket". The gasket acts as a demultiplexer of the
+four virtual channels streams, providing four separate parallel buses
+containing each virtual channel that are routed to CSIs or video
+multiplexers as described below.
+
+On i.MX6 solo/dual-lite, all four virtual channel buses are routed to
+two video multiplexers. Both CSI0 and CSI1 can receive any virtual
+channel, as selected by the video multiplexers.
+
+On i.MX6 Quad, virtual channel 0 is routed to IPU1-CSI0 (after selected
+by a video mux), virtual channels 1 and 2 are hard-wired to IPU1-CSI1
+and IPU2-CSI0, respectively, and virtual channel 3 is routed to
+IPU2-CSI1 (again selected by a video mux).
+
+ipuX_csiY_mux
+-------------
+
+These are the video multiplexers. They have two or more sink pads to
+select from either camera sensors with a parallel interface, or from
+MIPI CSI-2 virtual channels from imx6-mipi-csi2 entity. They have a
+single source pad that routes to a CSI (ipuX_csiY entities).
+
+On i.MX6 solo/dual-lite, there are two video mux entities. One sits
+in front of IPU1-CSI0 to select between a parallel sensor and any of
+the four MIPI CSI-2 virtual channels (a total of five sink pads). The
+other mux sits in front of IPU1-CSI1, and again has five sink pads to
+select between a parallel sensor and any of the four MIPI CSI-2 virtual
+channels.
+
+On i.MX6 Quad, there are two video mux entities. One sits in front of
+IPU1-CSI0 to select between a parallel sensor and MIPI CSI-2 virtual
+channel 0 (two sink pads). The other mux sits in front of IPU2-CSI1 to
+select between a parallel sensor and MIPI CSI-2 virtual channel 3 (two
+sink pads).
+
+ipuX_csiY
+---------
+
+These are the CSI entities. They have a single sink pad receiving from
+either a video mux or from a MIPI CSI-2 virtual channel as described
+above.
+
+This entity has two source pads. The first source pad can link directly
+to the ipuX_vdic entity or the ipuX_ic_prp entity, using hardware links
+that require no IDMAC memory buffer transfer.
+
+When the direct source pad is routed to the ipuX_ic_prp entity, frames
+from the CSI can be processed by one or both of the IC pre-processing
+tasks.
+
+When the direct source pad is routed to the ipuX_vdic entity, the VDIC
+will carry out motion-compensated de-interlace using "high motion" mode
+(see description of ipuX_vdic entity).
+
+The second source pad sends video frames directly to memory buffers
+via the SMFC and an IDMAC channel, bypassing IC pre-processing. This
+source pad is routed to a capture device node, with a node name of the
+format "ipuX_csiY capture".
+
+Note that since the IDMAC source pad makes use of an IDMAC channel,
+pixel reordering within the same colorspace can be carried out by the
+IDMAC channel. For example, if the CSI sink pad is receiving in UYVY
+order, the capture device linked to the IDMAC source pad can capture
+in YUYV order. Also, if the CSI sink pad is receiving a packed YUV
+format, the capture device can capture a planar YUV format such as
+YUV420.
+
+The IDMAC channel at the IDMAC source pad also supports simple
+interweave without motion compensation, which is activated if the source
+pad's field type is sequential top-bottom or bottom-top, and the
+requested capture interface field type is set to interlaced (t-b, b-t,
+or unqualified interlaced). The capture interface will enforce the same
+field order as the source pad field order (interlaced-bt if source pad
+is seq-bt, interlaced-tb if source pad is seq-tb).
+
+For events produced by ipuX_csiY, see ref:`imx_api_ipuX_csiY`.
+
+Cropping in ipuX_csiY
+---------------------
+
+The CSI supports cropping the incoming raw sensor frames. This is
+implemented in the ipuX_csiY entities at the sink pad, using the
+crop selection subdev API.
+
+The CSI also supports fixed divide-by-two downscaling independently in
+width and height. This is implemented in the ipuX_csiY entities at
+the sink pad, using the compose selection subdev API.
+
+The output rectangle at the ipuX_csiY source pad is the same as
+the compose rectangle at the sink pad. So the source pad rectangle
+cannot be negotiated, it must be set using the compose selection
+API at sink pad (if /2 downscale is desired, otherwise source pad
+rectangle is equal to incoming rectangle).
+
+To give an example of crop and /2 downscale, this will crop a
+1280x960 input frame to 640x480, and then /2 downscale in both
+dimensions to 320x240 (assumes ipu1_csi0 is linked to ipu1_csi0_mux):
+
+.. code-block:: none
+
+   media-ctl -V "'ipu1_csi0_mux':2[fmt:UYVY2X8/1280x960]"
+   media-ctl -V "'ipu1_csi0':0[crop:(0,0)/640x480]"
+   media-ctl -V "'ipu1_csi0':0[compose:(0,0)/320x240]"
+
+Frame Skipping in ipuX_csiY
+---------------------------
+
+The CSI supports frame rate decimation, via frame skipping. Frame
+rate decimation is specified by setting the frame intervals at
+sink and source pads. The ipuX_csiY entity then applies the best
+frame skip setting to the CSI to achieve the desired frame rate
+at the source pad.
+
+The following example reduces an assumed incoming 60 Hz frame
+rate by half at the IDMAC output source pad:
+
+.. code-block:: none
+
+   media-ctl -V "'ipu1_csi0':0[fmt:UYVY2X8/640x480@1/60]"
+   media-ctl -V "'ipu1_csi0':2[fmt:UYVY2X8/640x480@1/30]"
+
+Frame Interval Monitor in ipuX_csiY
+-----------------------------------
+
+See ref:`imx_api_FIM`.
+
+ipuX_vdic
+---------
+
+The VDIC carries out motion compensated de-interlacing, with three
+motion compensation modes: low, medium, and high motion. The mode is
+specified with the menu control V4L2_CID_DEINTERLACING_MODE. The VDIC
+has two sink pads and a single source pad.
+
+The direct sink pad receives from an ipuX_csiY direct pad. With this
+link the VDIC can only operate in high motion mode.
+
+When the IDMAC sink pad is activated, it receives from an output
+or mem2mem device node. With this pipeline, the VDIC can also operate
+in low and medium modes, because these modes require receiving
+frames from memory buffers. Note that an output or mem2mem device
+is not implemented yet, so this sink pad currently has no links.
+
+The source pad routes to the IC pre-processing entity ipuX_ic_prp.
+
+ipuX_ic_prp
+-----------
+
+This is the IC pre-processing entity. It acts as a router, routing
+data from its sink pad to one or both of its source pads.
+
+This entity has a single sink pad. The sink pad can receive from the
+ipuX_csiY direct pad, or from ipuX_vdic.
+
+This entity has two source pads. One source pad routes to the
+pre-process encode task entity (ipuX_ic_prpenc), the other to the
+pre-process viewfinder task entity (ipuX_ic_prpvf). Both source pads
+can be activated at the same time if the sink pad is receiving from
+ipuX_csiY. Only the source pad to the pre-process viewfinder task entity
+can be activated if the sink pad is receiving from ipuX_vdic (frames
+from the VDIC can only be processed by the pre-process viewfinder task).
+
+ipuX_ic_prpenc
+--------------
+
+This is the IC pre-processing encode entity. It has a single sink
+pad from ipuX_ic_prp, and a single source pad. The source pad is
+routed to a capture device node, with a node name of the format
+"ipuX_ic_prpenc capture".
+
+This entity performs the IC pre-process encode task operations:
+color-space conversion, resizing (downscaling and upscaling),
+horizontal and vertical flip, and 90/270 degree rotation. Flip
+and rotation are provided via standard V4L2 controls.
+
+Like the ipuX_csiY IDMAC source, this entity also supports simple
+de-interlace without motion compensation, and pixel reordering.
+
+ipuX_ic_prpvf
+-------------
+
+This is the IC pre-processing viewfinder entity. It has a single sink
+pad from ipuX_ic_prp, and a single source pad. The source pad is routed
+to a capture device node, with a node name of the format
+"ipuX_ic_prpvf capture".
+
+This entity is identical in operation to ipuX_ic_prpenc, with the same
+resizing and CSC operations and flip/rotation controls. It will receive
+and process de-interlaced frames from the ipuX_vdic if ipuX_ic_prp is
+receiving from ipuX_vdic.
+
+Like the ipuX_csiY IDMAC source, this entity supports simple
+interweaving without motion compensation. However, note that if the
+ipuX_vdic is included in the pipeline (ipuX_ic_prp is receiving from
+ipuX_vdic), it's not possible to use interweave in ipuX_ic_prpvf,
+since the ipuX_vdic has already carried out de-interlacing (with
+motion compensation) and therefore the field type output from
+ipuX_vdic can only be none (progressive).
+
+Capture Pipelines
+-----------------
+
+The following describe the various use-cases supported by the pipelines.
+
+The links shown do not include the backend sensor, video mux, or mipi
+csi-2 receiver links. This depends on the type of sensor interface
+(parallel or mipi csi-2). So these pipelines begin with:
+
+sensor -> ipuX_csiY_mux -> ...
+
+for parallel sensors, or:
+
+sensor -> imx6-mipi-csi2 -> (ipuX_csiY_mux) -> ...
+
+for mipi csi-2 sensors. The imx6-mipi-csi2 receiver may need to route
+to the video mux (ipuX_csiY_mux) before sending to the CSI, depending
+on the mipi csi-2 virtual channel, hence ipuX_csiY_mux is shown in
+parenthesis.
+
+Unprocessed Video Capture:
+--------------------------
+
+Send frames directly from sensor to camera device interface node, with
+no conversions, via ipuX_csiY IDMAC source pad:
+
+-> ipuX_csiY:2 -> ipuX_csiY capture
+
+IC Direct Conversions:
+----------------------
+
+This pipeline uses the preprocess encode entity to route frames directly
+from the CSI to the IC, to carry out scaling up to 1024x1024 resolution,
+CSC, flipping, and image rotation:
+
+-> ipuX_csiY:1 -> 0:ipuX_ic_prp:1 -> 0:ipuX_ic_prpenc:1 -> ipuX_ic_prpenc capture
+
+Motion Compensated De-interlace:
+--------------------------------
+
+This pipeline routes frames from the CSI direct pad to the VDIC entity to
+support motion-compensated de-interlacing (high motion mode only),
+scaling up to 1024x1024, CSC, flip, and rotation:
+
+-> ipuX_csiY:1 -> 0:ipuX_vdic:2 -> 0:ipuX_ic_prp:2 -> 0:ipuX_ic_prpvf:1 -> ipuX_ic_prpvf capture
+
+
+Usage Notes
+-----------
+
+To aid in configuration and for backward compatibility with V4L2
+applications that access controls only from video device nodes, the
+capture device interfaces inherit controls from the active entities
+in the current pipeline, so controls can be accessed either directly
+from the subdev or from the active capture device interface. For
+example, the FIM controls are available either from the ipuX_csiY
+subdevs or from the active capture device.
+
+The following are specific usage notes for the Sabre* reference
+boards:
+
+
+i.MX6Q SabreLite with OV5642 and OV5640
+---------------------------------------
+
+This platform requires the OmniVision OV5642 module with a parallel
+camera interface, and the OV5640 module with a MIPI CSI-2
+interface. Both modules are available from Boundary Devices:
+
+- https://boundarydevices.com/product/nit6x_5mp
+- https://boundarydevices.com/product/nit6x_5mp_mipi
+
+Note that if only one camera module is available, the other sensor
+node can be disabled in the device tree.
+
+The OV5642 module is connected to the parallel bus input on the i.MX
+internal video mux to IPU1 CSI0. It's i2c bus connects to i2c bus 2.
+
+The MIPI CSI-2 OV5640 module is connected to the i.MX internal MIPI CSI-2
+receiver, and the four virtual channel outputs from the receiver are
+routed as follows: vc0 to the IPU1 CSI0 mux, vc1 directly to IPU1 CSI1,
+vc2 directly to IPU2 CSI0, and vc3 to the IPU2 CSI1 mux. The OV5640 is
+also connected to i2c bus 2 on the SabreLite, therefore the OV5642 and
+OV5640 must not share the same i2c slave address.
+
+The following basic example configures unprocessed video capture
+pipelines for both sensors. The OV5642 is routed to ipu1_csi0, and
+the OV5640, transmitting on MIPI CSI-2 virtual channel 1 (which is
+imx6-mipi-csi2 pad 2), is routed to ipu1_csi1. Both sensors are
+configured to output 640x480, and the OV5642 outputs YUYV2X8, the
+OV5640 UYVY2X8:
+
+.. code-block:: none
+
+   # Setup links for OV5642
+   media-ctl -l "'ov5642 1-0042':0 -> 'ipu1_csi0_mux':1[1]"
+   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
+   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
+   # Setup links for OV5640
+   media-ctl -l "'ov5640 1-0040':0 -> 'imx6-mipi-csi2':0[1]"
+   media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
+   media-ctl -l "'ipu1_csi1':2 -> 'ipu1_csi1 capture':0[1]"
+   # Configure pads for OV5642 pipeline
+   media-ctl -V "'ov5642 1-0042':0 [fmt:YUYV2X8/640x480 field:none]"
+   media-ctl -V "'ipu1_csi0_mux':2 [fmt:YUYV2X8/640x480 field:none]"
+   media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/640x480 field:none]"
+   # Configure pads for OV5640 pipeline
+   media-ctl -V "'ov5640 1-0040':0 [fmt:UYVY2X8/640x480 field:none]"
+   media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/640x480 field:none]"
+   media-ctl -V "'ipu1_csi1':2 [fmt:AYUV32/640x480 field:none]"
+
+Streaming can then begin independently on the capture device nodes
+"ipu1_csi0 capture" and "ipu1_csi1 capture". The v4l2-ctl tool can
+be used to select any supported YUV pixelformat on the capture device
+nodes, including planar.
+
+i.MX6Q SabreAuto with ADV7180 decoder
+-------------------------------------
+
+On the i.MX6Q SabreAuto, an on-board ADV7180 SD decoder is connected to the
+parallel bus input on the internal video mux to IPU1 CSI0.
+
+The following example configures a pipeline to capture from the ADV7180
+video decoder, assuming NTSC 720x480 input signals, using simple
+interweave (unconverted and without motion compensation). The adv7180
+must output sequential or alternating fields (field type 'seq-bt' for
+NTSC, or 'alternate'):
+
+.. code-block:: none
+
+   # Setup links
+   media-ctl -l "'adv7180 3-0021':0 -> 'ipu1_csi0_mux':1[1]"
+   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
+   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
+   # Configure pads
+   media-ctl -V "'adv7180 3-0021':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
+   media-ctl -V "'ipu1_csi0_mux':2 [fmt:UYVY2X8/720x480]"
+   media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/720x480]"
+   # Configure "ipu1_csi0 capture" interface (assumed at /dev/video4)
+   v4l2-ctl -d4 --set-fmt-video=field=interlaced_bt
+
+Streaming can then begin on /dev/video4. The v4l2-ctl tool can also be
+used to select any supported YUV pixelformat on /dev/video4.
+
+This example configures a pipeline to capture from the ADV7180
+video decoder, assuming PAL 720x576 input signals, with Motion
+Compensated de-interlacing. The adv7180 must output sequential or
+alternating fields (field type 'seq-tb' for PAL, or 'alternate').

+
+i.MX6DL SabreAuto with ADV7180 decoder
+--------------------------------------
+
+On the i.MX6DL SabreAuto, an on-board ADV7180 SD decoder is connected to the
+parallel bus input on the internal video mux to IPU1 CSI0.
+
+The following example configures a pipeline to capture from the ADV7180
+video decoder, assuming NTSC 720x480 input signals, using simple
+interweave (unconverted and without motion compensation). The adv7180
+must output sequential or alternating fields (field type 'seq-bt' for
+NTSC, or 'alternate'):
+
+.. code-block:: none
+
+   # Setup links

+   # Configure pads
+   media-ctl -V "'adv7180 4-0021':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
+   media-ctl -V "'ipu1_csi0_mux':5 [fmt:UYVY2X8/720x480]"
+   media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/720x480]"
+   # Configure "ipu1_csi0 capture" interface (assumed at /dev/video0)
+   v4l2-ctl -d0 --set-fmt-video=field=interlaced_bt
+
+Streaming can then begin on /dev/video0. The v4l2-ctl tool can also be
+used to select any supported YUV pixelformat on /dev/video0.
+
+This example configures a pipeline to capture from the ADV7180
+video decoder, assuming PAL 720x576 input signals, with Motion
+Compensated de-interlacing. The adv7180 must output sequential or
+alternating fields (field type 'seq-tb' for PAL, or 'alternate').

+
+i.MX6Q SabreSD with MIPI CSI-2 OV5640
+-------------------------------------
+
+Similarly to i.MX6Q SabreLite, the i.MX6Q SabreSD supports a parallel
+interface OV5642 module on IPU1 CSI0, and a MIPI CSI-2 OV5640
+module. The OV5642 connects to i2c bus 1 and the OV5640 to i2c bus 2.
+
+The device tree for SabreSD includes OF graphs for both the parallel
+OV5642 and the MIPI CSI-2 OV5640, but as of this writing only the MIPI
+CSI-2 OV5640 has been tested, so the OV5642 node is currently disabled.
+The OV5640 module connects to MIPI connector J5. The NXP part number
+for the OV5640 module that connects to the SabreSD board is H120729.
+
+The following example configures unprocessed video capture pipeline to
+capture from the OV5640, transmitting on MIPI CSI-2 virtual channel 0:
+
+.. code-block:: none
+
+   # Setup links
+   media-ctl -l "'ov5640 1-003c':0 -> 'imx6-mipi-csi2':0[1]"
+   media-ctl -l "'imx6-mipi-csi2':1 -> 'ipu1_csi0_mux':0[1]"
+   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
+   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
+   # Configure pads
+   media-ctl -V "'ov5640 1-003c':0 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'imx6-mipi-csi2':1 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0_mux':0 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0':0 [fmt:AYUV32/640x480]"
+
+Streaming can then begin on "ipu1_csi0 capture" node. The v4l2-ctl
+tool can be used to select any supported pixelformat on the capture
+device node.
+
+To determine what is the /dev/video node correspondent to
+"ipu1_csi0 capture":
+
+.. code-block:: none
+
+   media-ctl -e "ipu1_csi0 capture"
+   /dev/video0
+
+/dev/video0 is the streaming element in this case.
+
+Starting the streaming via v4l2-ctl:
+
+.. code-block:: none
+
+   v4l2-ctl --stream-mmap -d /dev/video0
+
+Starting the streaming via Gstreamer and sending the content to the display:
+
+.. code-block:: none
+
+   gst-launch-1.0 v4l2src device=/dev/video0 ! kmssink
+
+The following example configures a direct conversion pipeline to capture
+from the OV5640, transmitting on MIPI CSI-2 virtual channel 0. It also
+shows colorspace conversion and scaling at IC output.
+
+.. code-block:: none
+
+   # Setup links
+   media-ctl -l "'ov5640 1-003c':0 -> 'imx6-mipi-csi2':0[1]"
+   media-ctl -l "'imx6-mipi-csi2':1 -> 'ipu1_csi0_mux':0[1]"
+   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
+   media-ctl -l "'ipu1_csi0':1 -> 'ipu1_ic_prp':0[1]"
+   media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
+   media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"
+   # Configure pads
+   media-ctl -V "'ov5640 1-003c':0 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'imx6-mipi-csi2':1 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0_mux':2 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0':1 [fmt:AYUV32/640x480]"
+   media-ctl -V "'ipu1_ic_prp':1 [fmt:AYUV32/640x480]"
+   media-ctl -V "'ipu1_ic_prpenc':1 [fmt:ARGB8888_1X32/800x600]"
+   # Set a format at the capture interface
+   v4l2-ctl -d /dev/video1 --set-fmt-video=pixelformat=RGB3
+
+Streaming can then begin on "ipu1_ic_prpenc capture" node.
+
+To determine what is the /dev/video node correspondent to
+"ipu1_ic_prpenc capture":
+
+.. code-block:: none
+
+   media-ctl -e "ipu1_ic_prpenc capture"
+   /dev/video1
+
+
+/dev/video1 is the streaming element in this case.
+
+Starting the streaming via v4l2-ctl:
+
+.. code-block:: none
+
+   v4l2-ctl --stream-mmap -d /dev/video1
+
+Starting the streaming via Gstreamer and sending the content to the display:
+
+.. code-block:: none
+
+   gst-launch-1.0 v4l2src device=/dev/video1 ! kmssink
+
+Known Issues
+------------
+
+1. When using 90 or 270 degree rotation control at capture resolutions
+   near the IC resizer limit of 1024x1024, and combined with planar
+   pixel formats (YUV420, YUV422p), frame capture will often fail with
+   no end-of-frame interrupts from the IDMAC channel. To work around
+   this, use lower resolution and/or packed formats (YUYV, RGB3, etc.)
+   when 90 or 270 rotations are needed.

+Intel Image Processing Unit 3 (IPU3) Imaging Unit (ImgU) driver
+===============================================================
+
+Copyright |copy| 2018 Intel Corporation
+
+Introduction
+============
+
+This file documents the Intel IPU3 (3rd generation Image Processing Unit)
+Imaging Unit drivers located under drivers/media/pci/intel/ipu3 (CIO2) as well
+as under drivers/staging/media/ipu3 (ImgU).
+
+The Intel IPU3 found in certain Kaby Lake (as well as certain Sky Lake)
+platforms (U/Y processor lines) is made up of two parts namely the Imaging Unit
+(ImgU) and the CIO2 device (MIPI CSI2 receiver).
+
+The CIO2 device receives the raw Bayer data from the sensors and outputs the
+frames in a format that is specific to the IPU3 (for consumption by the IPU3
+ImgU). The CIO2 driver is available as drivers/media/pci/intel/ipu3/ipu3-cio2*
+and is enabled through the CONFIG_VIDEO_IPU3_CIO2 config option.
+
+The Imaging Unit (ImgU) is responsible for processing images captured
+by the IPU3 CIO2 device. The ImgU driver sources can be found under
+drivers/staging/media/ipu3 directory. The driver is enabled through the
+CONFIG_VIDEO_IPU3_IMGU config option.
+
+The two driver modules are named ipu3_csi2 and ipu3_imgu, respectively.
+
+The drivers has been tested on Kaby Lake platforms (U/Y processor lines).
+
+Both of the drivers implement V4L2, Media Controller and V4L2 sub-device
+interfaces. The IPU3 CIO2 driver supports camera sensors connected to the CIO2
+MIPI CSI-2 interfaces through V4L2 sub-device sensor drivers.
+
+CIO2
+====
+
+The CIO2 is represented as a single V4L2 subdev, which provides a V4L2 subdev
+interface to the user space. There is a video node for each CSI-2 receiver,
+with a single media controller interface for the entire device.
+
+The CIO2 contains four independent capture channel, each with its own MIPI CSI-2
+receiver and DMA engine. Each channel is modelled as a V4L2 sub-device exposed
+to userspace as a V4L2 sub-device node and has two pads:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+
+    * - pad
+      - direction
+      - purpose
+
+    * - 0
+      - sink
+      - MIPI CSI-2 input, connected to the sensor subdev
+
+    * - 1
+      - source
+      - Raw video capture, connected to the V4L2 video interface
+
+The V4L2 video interfaces model the DMA engines. They are exposed to userspace
+as V4L2 video device nodes.
+
+Capturing frames in raw Bayer format
+------------------------------------
+
+CIO2 MIPI CSI2 receiver is used to capture frames (in packed raw Bayer format)
+from the raw sensors connected to the CSI2 ports. The captured frames are used
+as input to the ImgU driver.
+
+Image processing using IPU3 ImgU requires tools such as raw2pnm [#f1]_, and
+yavta [#f2]_ due to the following unique requirements and / or features specific
+to IPU3.
+
+-- The IPU3 CSI2 receiver outputs the captured frames from the sensor in packed
+raw Bayer format that is specific to IPU3.
+
+-- Multiple video nodes have to be operated simultaneously.
+
+Let us take the example of ov5670 sensor connected to CSI2 port 0, for a
+2592x1944 image capture.
+
+Using the media contorller APIs, the ov5670 sensor is configured to send
+frames in packed raw Bayer format to IPU3 CSI2 receiver.
+
+# This example assumes /dev/media0 as the CIO2 media device
+
+export MDEV=/dev/media0
+
+# and that ov5670 sensor is connected to i2c bus 10 with address 0x36
+
+export SDEV=$(media-ctl -d $MDEV -e "ov5670 10-0036")
+
+# Establish the link for the media devices using media-ctl [#f3]_
+media-ctl -d $MDEV -l "ov5670:0 -> ipu3-csi2 0:0[1]"
+
+# Set the format for the media devices
+media-ctl -d $MDEV -V "ov5670:0 [fmt:SGRBG10/2592x1944]"
+
+media-ctl -d $MDEV -V "ipu3-csi2 0:0 [fmt:SGRBG10/2592x1944]"
+
+media-ctl -d $MDEV -V "ipu3-csi2 0:1 [fmt:SGRBG10/2592x1944]"
+
+Once the media pipeline is configured, desired sensor specific settings
+(such as exposure and gain settings) can be set, using the yavta tool.
+
+e.g
+
+yavta -w 0x009e0903 444 $SDEV
+
+yavta -w 0x009e0913 1024 $SDEV
+
+yavta -w 0x009e0911 2046 $SDEV
+
+Once the desired sensor settings are set, frame captures can be done as below.
+
+e.g
+
+yavta --data-prefix -u -c10 -n5 -I -s2592x1944 --file=/tmp/frame-#.bin \
+      -f IPU3_SGRBG10 $(media-ctl -d $MDEV -e "ipu3-cio2 0")
+
+With the above command, 10 frames are captured at 2592x1944 resolution, with
+sGRBG10 format and output as IPU3_SGRBG10 format.
+
+The captured frames are available as /tmp/frame-#.bin files.
+
+ImgU
+====
+
+The ImgU is represented as two V4L2 subdevs, each of which provides a V4L2
+subdev interface to the user space.
+
+Each V4L2 subdev represents a pipe, which can support a maximum of 2 streams.
+This helps to support advanced camera features like Continuous View Finder (CVF)
+and Snapshot During Video(SDV).
+
+The ImgU contains two independent pipes, each modelled as a V4L2 sub-device
+exposed to userspace as a V4L2 sub-device node.
+
+Each pipe has two sink pads and three source pads for the following purpose:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+
+    * - pad
+      - direction
+      - purpose
+
+    * - 0
+      - sink
+      - Input raw video stream
+
+    * - 1
+      - sink
+      - Processing parameters
+
+    * - 2
+      - source
+      - Output processed video stream
+
+    * - 3
+      - source
+      - Output viewfinder video stream
+
+    * - 4
+      - source
+      - 3A statistics
+
+Each pad is connected to a corresponding V4L2 video interface, exposed to 
+userspace as a V4L2 video device node.
+
+Device operation
+----------------
+
+With ImgU, once the input video node ("ipu3-imgu 0/1":0, in
+<entity>:<pad-number> format) is queued with buffer (in packed raw Bayer
+format), ImgU starts processing the buffer and produces the video output in YUV
+format and statistics output on respective output nodes. The driver is expected
+to have buffers ready for all of parameter, output and statistics nodes, when
+input video node is queued with buffer.
+
+At a minimum, all of input, main output, 3A statistics and viewfinder
+video nodes should be enabled for IPU3 to start image processing.
+
+Each ImgU V4L2 subdev has the following set of video nodes.
+
+input, output and viewfinder video nodes
+----------------------------------------
+
+The frames (in packed raw Bayer format specific to the IPU3) received by the
+input video node is processed by the IPU3 Imaging Unit and are output to 2 video
+nodes, with each targeting a different purpose (main output and viewfinder
+output).
+
+Details onand the Bayer format specific to the IPU3 can be found in
+:ref:`v4l2-pix-fmt-ipu3-sbggr10`.
+
+The driver supports V4L2 Video Capture Interface as defined at :ref:`devices`.
+
+Only the multi-planar API is supported. More details can be found at
+:ref:`planar-apis`.
+
+Parameters video node
+---------------------
+
+The parameters video node receives the ImgU algorithm parameters that are used
+to configure how the ImgU algorithms process the image.
+
+Details on processing parameters specific to the IPU3 can be found in
+:ref:`v4l2-meta-fmt-params`.
+
+3A statistics video node
+------------------------
+
+3A statistics video node is used by the ImgU driver to output the 3A (auto
+focus, auto exposure and auto white balance) statistics for the frames that are
+being processed by the ImgU to user space applications. User space applications
+can use this statistics data to compute the desired algorithm parameters for
+the ImgU.
+
+Configuring the Intel IPU3
+==========================
+
+The IPU3 ImgU pipelines can be configured using the Media Controller, defined at
+:ref:`media_controller`.
+
+Running mode and firmware binary selection
+------------------------------------------
+
+ImgU works based on firmware, currently the ImgU firmware support run 2 pipes in
+time-sharing with single input frame data. Each pipe can run at certain mode -
+"VIDEO" or "STILL", "VIDEO" mode is commonly used for video frames capture, and
+"STILL" is used for still frame capture. However, you can also select "VIDEO" to
+capture still frames if you want to capture images with less system load and
+power. For "STILL" mode, ImgU will try to use smaller BDS factor and output
+larger bayer frame for further YUV processing than "VIDEO" mode to get high
+quality images. Besides, "STILL" mode need XNR3 to do noise reduction, hence
+"STILL" mode will need more power and memory bandwidth than "VIDEO" mode. TNR
+will be enabled in "VIDEO" mode and bypassed by "STILL" mode. ImgU is running at
+“VIDEO” mode by default, the user can use v4l2 control V4L2_CID_INTEL_IPU3_MODE
+(currently defined in drivers/staging/media/ipu3/include/intel-ipu3.h) to query
+and set the running mode. For user, there is no difference for buffer queueing
+between the "VIDEO" and "STILL" mode, mandatory input and main output node
+should be enabled and buffers need be queued, the statistics and the view-finder
+queues are optional.
+
+The firmware binary will be selected according to current running mode, such log
+"using binary if_to_osys_striped " or "using binary if_to_osys_primary_striped"
+could be observed if you enable the ImgU dynamic debug, the binary
+if_to_osys_striped is selected for "VIDEO" and the binary
+"if_to_osys_primary_striped" is selected for "STILL".
+
+
+Processing the image in raw Bayer format
+----------------------------------------
+
+Configuring ImgU V4L2 subdev for image processing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ImgU V4L2 subdevs have to be configured with media controller APIs to have
+all the video nodes setup correctly.
+
+Let us take "ipu3-imgu 0" subdev as an example.
+
+media-ctl -d $MDEV -r
+
+media-ctl -d $MDEV -l "ipu3-imgu 0 input":0 -> "ipu3-imgu 0":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":2 -> "ipu3-imgu 0 output":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":3 -> "ipu3-imgu 0 viewfinder":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":4 -> "ipu3-imgu 0 3a stat":0[1]
+
+Also the pipe mode of the corresponding V4L2 subdev should be set as desired
+(e.g 0 for video mode or 1 for still mode) through the control id 0x009819a1 as
+below.
+
+yavta -w "0x009819A1 1" /dev/v4l-subdev7
+
+Certain hardware blocks in ImgU pipeline can change the frame resolution by
+cropping or scaling, these hardware blocks include Input Feeder(IF), Bayer Down
+Scaler (BDS) and Geometric Distortion Correction (GDC).
+There is also a block which can change the frame resolution - YUV Scaler, it is
+only applicable to the secondary output.
+
+RAW Bayer frames go through these ImgU pipeline hardware blocks and the final
+processed image output to the DDR memory.
+
+.. kernel-figure::  ipu3_rcb.svg
+   :alt: ipu3 resolution blocks image
+
+   IPU3 resolution change hardware blocks
+
+**Input Feeder**
+
+Input Feeder gets the Bayer frame data from the sensor, it can enable cropping
+of lines and columns from the frame and then store pixels into device's internal
+pixel buffer which are ready to readout by following blocks.
+
+**Bayer Down Scaler**
+
+Bayer Down Scaler is capable of performing image scaling in Bayer domain, the
+downscale factor can be configured from 1X to 1/4X in each axis with
+configuration steps of 0.03125 (1/32).
+
+**Geometric Distortion Correction**
+
+Geometric Distortion Correction is used to performe correction of distortions
+and image filtering. It needs some extra filter and envelop padding pixels to
+work, so the input resolution of GDC should be larger than the output
+resolution.
+
+**YUV Scaler**
+
+YUV Scaler which similar with BDS, but it is mainly do image down scaling in
+YUV domain, it can support up to 1/12X down scaling, but it can not be applied
+to the main output.
+
+The ImgU V4L2 subdev has to be configured with the supported resolutions in all
+the above hardware blocks, for a given input resolution.
+For a given supported resolution for an input frame, the Input Feeder, Bayer
+Down Scaler and GDC blocks should be configured with the supported resolutions
+as each hardware block has its own alignment requirement.
+
+You must configure the output resolution of the hardware blocks smartly to meet
+the hardware requirement along with keeping the maximum field of view. The
+intermediate resolutions can be generated by specific tool -
+
+https://github.com/intel/intel-ipu3-pipecfg
+
+This tool can be used to generate intermediate resolutions. More information can
+be obtained by looking at the following IPU3 ImgU configuration table.
+
+https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master
+
+Under baseboard-poppy/media-libs/cros-camera-hal-configs-poppy/files/gcss
+directory, graph_settings_ov5670.xml can be used as an example.
+
+The following steps prepare the ImgU pipeline for the image processing.
+
+1. The ImgU V4L2 subdev data format should be set by using the
+VIDIOC_SUBDEV_S_FMT on pad 0, using the GDC width and height obtained above.
+
+2. The ImgU V4L2 subdev cropping should be set by using the
+VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_CROP as the target,
+using the input feeder height and width.
+
+3. The ImgU V4L2 subdev composing should be set by using the
+VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_COMPOSE as the target,
+using the BDS height and width.
+
+For the ov5670 example, for an input frame with a resolution of 2592x1944
+(which is input to the ImgU subdev pad 0), the corresponding resolutions
+for input feeder, BDS and GDC are 2592x1944, 2592x1944 and 2560x1920
+respectively.
+
+Once this is done, the received raw Bayer frames can be input to the ImgU
+V4L2 subdev as below, using the open source application v4l2n [#f1]_.
+
+For an image captured with 2592x1944 [#f4]_ resolution, with desired output
+resolution as 2560x1920 and viewfinder resolution as 2560x1920, the following
+v4l2n command can be used. This helps process the raw Bayer frames and produces
+the desired results for the main output image and the viewfinder output, in NV12
+format.
+
+v4l2n --pipe=4 --load=/tmp/frame-#.bin --open=/dev/video4
+--fmt=type:VIDEO_OUTPUT_MPLANE,width=2592,height=1944,pixelformat=0X47337069
+--reqbufs=type:VIDEO_OUTPUT_MPLANE,count:1 --pipe=1 --output=/tmp/frames.out
+--open=/dev/video5
+--fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
+--reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=2 --output=/tmp/frames.vf
+--open=/dev/video6
+--fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
+--reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=3 --open=/dev/video7
+--output=/tmp/frames.3A --fmt=type:META_CAPTURE,?
+--reqbufs=count:1,type:META_CAPTURE --pipe=1,2,3,4 --stream=5
+
+You can also use yavta [#f2]_ command to do same thing as above:
+
+.. code-block:: none
+
+	yavta --data-prefix -Bcapture-mplane -c10 -n5 -I -s2592x1944 \
+	--file=frame-#.out-f NV12 /dev/video5 & \
+	yavta --data-prefix -Bcapture-mplane -c10 -n5 -I -s2592x1944 \
+	--file=frame-#.vf -f NV12 /dev/video6 & \
+	yavta --data-prefix -Bmeta-capture -c10 -n5 -I \
+	--file=frame-#.3a /dev/video7 & \
+	yavta --data-prefix -Boutput-mplane -c10 -n5 -I -s2592x1944 \
+	--file=/tmp/frame-in.cio2 -f IPU3_SGRBG10 /dev/video4
+
+where /dev/video4, /dev/video5, /dev/video6 and /dev/video7 devices point to
+input, output, viewfinder and 3A statistics video nodes respectively.
+
+Converting the raw Bayer image into YUV domain
+----------------------------------------------
+
+The processed images after the above step, can be converted to YUV domain
+as below.
+
+Main output frames
+~~~~~~~~~~~~~~~~~~
+
+raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.out /tmp/frames.out.ppm
+
+where 2560x1920 is output resolution, NV12 is the video format, followed
+by input frame and output PNM file.
+
+Viewfinder output frames
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.vf /tmp/frames.vf.ppm
+
+where 2560x1920 is output resolution, NV12 is the video format, followed
+by input frame and output PNM file.

+
+======================== =======================================================
+Name			 Description
+======================== =======================================================
+Optical Black Correction Optical Black Correction block subtracts a pre-defined
+			 value from the respective pixel values to obtain better
+			 image quality.
+			 Defined in :c:type:`ipu3_uapi_obgrid_param`.
+Linearization		 This algo block uses linearization parameters to
+			 address non-linearity sensor effects. The Lookup table
+			 table is defined in
+			 :c:type:`ipu3_uapi_isp_lin_vmem_params`.
+SHD			 Lens shading correction is used to correct spatial
+			 non-uniformity of the pixel response due to optical
+			 lens shading. This is done by applying a different gain
+			 for each pixel. The gain, black level etc are
+			 configured in :c:type:`ipu3_uapi_shd_config_static`.
+BNR			 Bayer noise reduction block removes image noise by
+			 applying a bilateral filter.
+			 See :c:type:`ipu3_uapi_bnr_static_config` for details.
+ANR			 Advanced Noise Reduction is a block based algorithm
+			 that performs noise reduction in the Bayer domain. The
+			 convolution matrix etc can be found in
+			 :c:type:`ipu3_uapi_anr_config`.
+DM			 Demosaicing converts raw sensor data in Bayer format
+			 into RGB (Red, Green, Blue) presentation. Then add
+			 outputs of estimation of Y channel for following stream
+			 processing by Firmware. The struct is defined as
+			 :c:type:`ipu3_uapi_dm_config`.
+Color Correction	 Color Correction algo transforms sensor specific color
+			 space to the standard "sRGB" color space. This is done
+			 by applying 3x3 matrix defined in
+			 :c:type:`ipu3_uapi_ccm_mat_config`.
+Gamma correction	 Gamma correction :c:type:`ipu3_uapi_gamma_config` is a
+			 basic non-linear tone mapping correction that is
+			 applied per pixel for each pixel component.
+CSC			 Color space conversion transforms each pixel from the
+			 RGB primary presentation to YUV (Y: brightness,
+			 UV: Luminance) presentation. This is done by applying
+			 a 3x3 matrix defined in
+			 :c:type:`ipu3_uapi_csc_mat_config`
+CDS			 Chroma down sampling
+			 After the CSC is performed, the Chroma Down Sampling
+			 is applied for a UV plane down sampling by a factor
+			 of 2 in each direction for YUV 4:2:0 using a 4x2
+			 configurable filter :c:type:`ipu3_uapi_cds_params`.
+CHNR			 Chroma noise reduction
+			 This block processes only the chrominance pixels and
+			 performs noise reduction by cleaning the high
+			 frequency noise.
+			 See struct :c:type:`ipu3_uapi_yuvp1_chnr_config`.
+TCC			 Total color correction as defined in struct
+			 :c:type:`ipu3_uapi_yuvp2_tcc_static_config`.
+XNR3			 eXtreme Noise Reduction V3 is the third revision of
+			 noise reduction algorithm used to improve image
+			 quality. This removes the low frequency noise in the
+			 captured image. Two related structs are  being defined,
+			 :c:type:`ipu3_uapi_isp_xnr3_params` for ISP data memory
+			 and :c:type:`ipu3_uapi_isp_xnr3_vmem_params` for vector
+			 memory.
+TNR			 Temporal Noise Reduction block compares successive
+			 frames in time to remove anomalies / noise in pixel
+			 values. :c:type:`ipu3_uapi_isp_tnr3_vmem_params` and
+			 :c:type:`ipu3_uapi_isp_tnr3_params` are defined for ISP
+			 vector and data memory respectively.

+Other often encountered acronyms not listed in above table:
+
+	ACC
+		Accelerator cluster
+	AWB_FR
+		Auto white balance filter response statistics
+	BDS
+		Bayer downscaler parameters
+	CCM
+		Color correction matrix coefficients
+	IEFd
+		Image enhancement filter directed
+	Obgrid
+		Optical black level compensation
+	OSYS
+		Output system configuration
+	ROI
+		Region of interest
+	YDS
+		Y down sampling
+	YTM
+		Y-tone mapping
+
+A few stages of the pipeline will be executed by firmware running on the ISP
+processor, while many others will use a set of fixed hardware blocks also
+called accelerator cluster (ACC) to crunch pixel data and produce statistics.
+
+ACC parameters of individual algorithms, as defined by
+:c:type:`ipu3_uapi_acc_param`, can be chosen to be applied by the user
+space through struct :c:type:`ipu3_uapi_flags` embedded in
+:c:type:`ipu3_uapi_params` structure. For parameters that are configured as
+not enabled by the user space, the corresponding structs are ignored by the
+driver, in which case the existing configuration of the algorithm will be
+preserved.

+Vaio Picturebook Motion Eye Camera Driver
+=========================================
+
+Copyright |copy| 2001-2004 Stelian Pop <stelian@popies.net>
+
+Copyright |copy| 2001-2002 Alcôve <www.alcove.com>
+
+Copyright |copy| 2000 Andrew Tridgell <tridge@samba.org>
+
+This driver enable the use of video4linux compatible applications with the
+Motion Eye camera. This driver requires the "Sony Laptop Extras" driver (which
+can be found in the "Misc devices" section of the kernel configuration utility)
+to be compiled and installed (using its "camera=1" parameter).
+
+It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480.
+
+Grabbing is supported in packed YUV colorspace only.
+
+MJPEG hardware grabbing is supported via a private API (see below).
+
+Hardware supported
+------------------
+
+This driver supports the 'second' version of the MotionEye camera :)
+
+The first version was connected directly on the video bus of the Neomagic
+video card and is unsupported.
+
+The second one, made by Kawasaki Steel is fully supported by this
+driver (PCI vendor/device is 0x136b/0xff01)
+
+The third one, present in recent (more or less last year) Picturebooks
+(C1M* models), is not supported. The manufacturer has given the specs
+to the developers under a NDA (which allows the development of a GPL
+driver however), but things are not moving very fast (see
+http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
+
+There is a forth model connected on the USB bus in TR1* Vaio laptops.
+This camera is not supported at all by the current driver, in fact
+little information if any is available for this camera
+(USB vendor/device is 0x054c/0x0107).
+
+Driver options
+--------------
+
+Several options can be passed to the meye driver using the standard
+module argument syntax (<param>=<value> when passing the option to the
+module or meye.<param>=<value> on the kernel boot line when meye is
+statically linked into the kernel). Those options are:
+
+.. code-block:: none
+
+	gbuffers:	number of capture buffers, default is 2 (32 max)
+
+	gbufsize:	size of each capture buffer, default is 614400
+
+	video_nr:	video device to register (0 = /dev/video0, etc)
+
+Module use
+----------
+
+In order to automatically load the meye module on use, you can put those lines
+in your /etc/modprobe.d/meye.conf file:
+
+.. code-block:: none
+
+	alias char-major-81 videodev
+	alias char-major-81-0 meye
+	options meye gbuffers=32
+
+Usage:
+------
+
+.. code-block:: none
+
+	xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
+		for display and uncompressed video capture:
+
+			xawtv -c /dev/video0 -geometry 640x480
+				or
+			xawtv -c /dev/video0 -geometry 320x240
+
+	motioneye (<http://popies.net/meye/>)
+		for getting ppm or jpg snapshots, mjpeg video
+
+Bugs / Todo
+-----------
+
+- 'motioneye' still uses the meye private v4l1 API extensions.

+OMAP 3 Image Signal Processor (ISP) driver
+==========================================

+
+
+Introduction
+------------
+
+This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
+driver located under drivers/media/platform/omap3isp. The original driver was
+written by Texas Instruments but since that it has been rewritten (twice) at
+Nokia.
+
+The driver has been successfully used on the following versions of OMAP 3:
+
+- 3430
+- 3530
+- 3630
+
+The driver implements V4L2, Media controller and v4l2_subdev interfaces.
+Sensor, lens and flash drivers using the v4l2_subdev interface in the kernel
+are supported.
+
+
+Split to subdevs
+----------------
+
+The OMAP 3 ISP is split into V4L2 subdevs, each of the blocks inside the ISP
+having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
+interface to userspace.
+
+- OMAP3 ISP CCP2
+- OMAP3 ISP CSI2a
+- OMAP3 ISP CCDC
+- OMAP3 ISP preview
+- OMAP3 ISP resizer
+- OMAP3 ISP AEWB
+- OMAP3 ISP AF
+- OMAP3 ISP histogram
+
+Each possible link in the ISP is modelled by a link in the Media controller
+interface. For an example program see [#]_.
+
+
+Controlling the OMAP 3 ISP
+--------------------------
+
+In general, the settings given to the OMAP 3 ISP take effect at the beginning
+of the following frame. This is done when the module becomes idle during the
+vertical blanking period on the sensor. In memory-to-memory operation the pipe
+is run one frame at a time. Applying the settings is done between the frames.
+
+All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver,
+insist on receiving complete frames. Sensors must thus never send the ISP
+partial frames.
+
+Autoidle does have issues with some ISP blocks on the 3430, at least.
+Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle
+is non-zero.
+

+PCI drivers
+===========
+
+The PCI boards are identified by an identification called PCI ID. The PCI ID
+is actually composed by two parts:
+
+	- Vendor ID and device ID;
+	- Subsystem ID and Subsystem device ID;
+
+The ``lspci -nn`` command allows identifying the vendor/device PCI IDs:
+
+.. code-block:: none
+   :emphasize-lines: 3
+
+    $ lspci -nn
+    ...

+    01:00.0 Multimedia video controller [0400]: Conexant Systems, Inc. CX23887/8 PCIe Broadcast Audio and Video Decoder with 3D Comb [14f1:8880] (rev 0f)
+    02:01.0 Multimedia video controller [0400]: Internext Compression Inc iTVC15 (CX23415) Video Decoder [4444:0803] (rev 01)

+    02:03.0 Multimedia video controller [0400]: Brooktree Corporation Bt878 Video Capture [109e:036e] (rev 11)
+    ...
+
+The subsystem IDs can be obtained using ``lspci -vn``
+
+.. code-block:: none
+   :emphasize-lines: 4
+
+    $ lspci -vn
+    ...
+	00:0a.0 0480: 1131:7133 (rev d1)
+		Subsystem: 1461:f01d
+		Flags: bus master, medium devsel, latency 32, IRQ 209
+		Memory at e2002000 (32-bit, non-prefetchable) [size=2K]
+		Capabilities: [40] Power Management version 2
+    ...
+
+At the above example, the first card uses the ``saa7134`` driver, and
+has a vendor/device PCI ID equal to ``1131:7133`` and a PCI subsystem
+ID equal to ``1461:f01d`` (see :doc:`Saa7134 card list<saa7134-cardlist>`).
+
+Unfortunately, sometimes the same PCI subsystem ID is used by different
+products. So, several media drivers allow passing a ``card=`` parameter,
+in order to setup a card number that would match the correct settings for
+an specific board.
+
+The current supported PCI/PCIe cards (not including staging drivers) are

+Platform drivers
+================
+
+There are several drivers that are focused on providing support for
+functionality that are already included at the main board, and don't
+use neither USB nor PCI bus. Those drivers are called platform
+drivers, and are very popular on embedded devices.

+Infrared remote control support in video4linux drivers
+======================================================
+
+Authors: Gerd Hoffmann, Mauro Carvalho Chehab
+
+Basics
+======
+
+Most analog and digital TV boards support remote controllers. Several of
+them have a microprocessor that receives the IR carriers, convert into
+pulse/space sequences and then to scan codes, returning such codes to
+userspace ("scancode mode"). Other boards return just the pulse/space
+sequences ("raw mode").
+
+The support for remote controller in scancode mode is provided by the
+standard Linux input layer. The support for raw mode is provided via LIRC.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_. It provides
+two tools to handle remote controllers:
+
+- ir-keytable: provides a way to query the remote controller, list the
+  protocols it supports, enable in-kernel support for IR decoder or
+  switch the protocol and to test the reception of scan codes;
+
+- ir-ctl: provide tools to handle remote controllers that support raw mode
+  via LIRC interface.
+
+Usually, the remote controller module is auto-loaded when the TV card is
+detected. However, for a few devices, you need to manually load the
+ir-kbd-i2c module.
+
+How it works
+============
+
+The modules register the remote as keyboard within the linux input
+layer, i.e. you'll see the keys of the remote as normal key strokes
+(if CONFIG_INPUT_KEYBOARD is enabled).
+
+Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
+applications to access the remote via /dev/input/event<n> devices.
+The udev/systemd will automatically create the devices. If you install
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_, it may also
+automatically load a different keytable than the default one. Please see
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ ir-keytable.1

+
+The ir-keytable tool is nice for trouble shooting, i.e. to check
+whenever the input device is really present, which of the devices it
+is, check whenever pressing keys on the remote actually generates
+events and the like.  You can also use any other input utility that changes
+the keymaps, like the input kbd utility.
+
+
+Using with lircd
+----------------
+
+The latest versions of the lircd daemon supports reading events from the
+linux input layer (via event device). It also supports receiving IR codes
+in lirc mode.
+
+
+Using without lircd
+-------------------
+
+Xorg recognizes several IR keycodes that have its numerical value lower
+than 247. With the advent of Wayland, the input driver got updated too,
+and should now accept all keycodes. Yet, you may want to just reasign
+the keycodes to something that your favorite media application likes.
+
+This can be done by setting
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ to load your own
+keytable in runtime. Please read  ir-keytable.1 man page for details.

+The saa7134 driver
+==================
+
+Author Gerd Hoffmann
+
+
+This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
+boards.
+
+
+Status
+------
+
+Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
+
+As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
+list of known TV cards and saa7134-cards.c for the drivers card
+configuration info.
+
+
+Build
+-----
+
+Once you pick up a Kernel source, you should configure, build,
+install and boot the new kernel.  You'll need at least
+these config options::
+
+    ./scripts/config -e PCI
+    ./scripts/config -e INPUT
+    ./scripts/config -m I2C
+    ./scripts/config -m MEDIA_SUPPORT
+    ./scripts/config -e MEDIA_PCI_SUPPORT
+    ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
+    ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
+    ./scripts/config -e MEDIA_RADIO_SUPPORT
+    ./scripts/config -e RC_CORE
+    ./scripts/config -e MEDIA_SUBDRV_AUTOSELECT
+    ./scripts/config -m VIDEO_SAA7134
+    ./scripts/config -e SAA7134_ALSA
+    ./scripts/config -e VIDEO_SAA7134_RC
+    ./scripts/config -e VIDEO_SAA7134_DVB
+    ./scripts/config -e VIDEO_SAA7134_GO7007
+
+To build and install, you should run::
+
+    make && make modules_install && make install
+
+Once the new Kernel is booted, saa7134 driver should be loaded automatically.
+
+Depending on the card you might have to pass ``card=<nr>`` as insmod option.
+If so, please check :doc:`saa7134-cardlist` for valid choices.
+
+Once you have your card type number, you can pass a modules configuration
+via a file (usually, it is either ``/etc/modules.conf`` or some file at
+``/etc/modules-load.d/``, but the actual place depends on your
+distribution), with this content::
+
+    options saa7134 card=13 # Assuming that your card type is #13
+
+
+Changes / Fixes
+---------------
+
+Please mail to linux-media AT vger.kernel.org unified diffs against
+the linux media git tree:
+
+    https://git.linuxtv.org/media_tree.git/
+
+This is done by committing a patch at a clone of the git tree and
+submitting the patch using ``git send-email``. Don't forget to
+describe at the lots  what it changes / which problem it fixes / whatever
+it is good for ...
+
+
+Known Problems
+--------------
+
+* The tuner for the flyvideos isn't detected automatically and the
+  default might not work for you depending on which version you have.
+  There is a ``tuner=`` insmod option to override the driver's default.

+USB drivers
+===========
+
+The USB boards are identified by an identification called USB ID.
+
+The ``lsusb`` command allows identifying the USB IDs::
+
+    $ lsusb
+    ...
+    Bus 001 Device 015: ID 046d:082d Logitech, Inc. HD Pro Webcam C920
+    Bus 001 Device 074: ID 2040:b131 Hauppauge
+    Bus 001 Device 075: ID 2013:024f PCTV Systems nanoStick T2 290e
+    ...
+
+Newer camera devices use a standard way to expose themselves as such,
+via USB Video Class. Those cameras are automatically supported by the
+``uvc-driver``.
+
+Older cameras and TV USB devices uses USB Vendor Classes: each vendor
+defines its own way to access the device. This section contains
+card lists for such vendor-class devices.
+
+While this is not as common as on PCI, sometimes the same USB ID is used
+by different products. So, several media drivers allow passing a ``card=``
+parameter, in order to setup a card number that would match the correct
+settings for an specific product type.
+
+The current supported USB cards (not including staging drivers) are
+listed below\ [#]_.
+
+.. [#]
+
+   some of the drivers have sub-drivers, not shown at this table.
+   In particular, gspca driver has lots of sub-drivers,
+   for cameras not supported by the USB Video Class (UVC) driver,
+   as shown at :doc:`gspca card list <gspca-cardlist>`.

+The Virtual Media Controller Driver (vimc)
+==========================================
+
+The vimc driver emulates complex video hardware using the V4L2 API and the Media
+API. It has a capture device and three subdevices: sensor, debayer and scaler.
+
+Topology
+--------
+
+The topology is hardcoded, although you could modify it in vimc-core and
+recompile the driver to achieve your own topology. This is the default topology:
+
+.. _vimc_topology_graph:
+
+.. kernel-figure:: vimc.dot
+    :alt:   Diagram of the default media pipeline topology
+    :align: center
+
+    Media pipeline graph on vimc
+
+Configuring the topology
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each subdevice will come with its default configuration (pixelformat, height,
+width, ...). One needs to configure the topology in order to match the
+configuration on each linked subdevice to stream frames through the pipeline.
+If the configuration doesn't match, the stream will fail. The ``v4l-utils``
+package is a bundle of user-space applications, that comes with ``media-ctl`` and
+``v4l2-ctl`` that can be used to configure the vimc configuration. This sequence
+of commands fits for the default topology:
+
+.. code-block:: bash
+
+        media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
+        media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'
+        media-ctl -d platform:vimc -V '"Sensor B":0[fmt:SBGGR8_1X8/640x480]'
+        media-ctl -d platform:vimc -V '"Debayer B":0[fmt:SBGGR8_1X8/640x480]'
+        v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=1920,height=1440
+        v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81
+        v4l2-ctl -z platform:vimc -d "Raw Capture 1" -v pixelformat=BA81
+
+Subdevices
+----------
+
+Subdevices define the behavior of an entity in the topology. Depending on the
+subdevice, the entity can have multiple pads of type source or sink.
+
+vimc-sensor:
+	Generates images in several formats using video test pattern generator.
+	Exposes:
+
+	* 1 Pad source
+
+vimc-debayer:
+	Transforms images in bayer format into a non-bayer format.
+	Exposes:
+
+	* 1 Pad sink
+	* 1 Pad source
+
+vimc-scaler:
+	Scale up the image by a factor of 3. E.g.: a 640x480 image becomes a
+        1920x1440 image. (this value can be configured, see at
+        `Module options`_).
+	Exposes:
+
+	* 1 Pad sink
+	* 1 Pad source
+
+vimc-capture:
+	Exposes node /dev/videoX to allow userspace to capture the stream.
+	Exposes:
+
+	* 1 Pad sink
+	* 1 Pad source
+
+
+Module options
+--------------
+
+Vimc has a module parameter to configure the driver.
+
+* ``sca_mult=<unsigned int>``
+
+        Image size multiplier factor to be used to multiply both width and
+        height, so the image size will be ``sca_mult^2`` bigger than the
+        original one. Currently, only supports scaling up (the default value
+        is 3).

+Zoran 364xx based USB webcam module
+===================================
+
+site: http://royale.zerezo.com/zr364xx/
+
+mail: royale@zerezo.com
+
+
+Introduction
+------------
+
+
+This brings support under Linux for the Aiptek PocketDV 3300 and similar
+devices in webcam mode. If you just want to get on your PC the pictures
+and movies on the camera, you should use the usb-storage module instead.
+
+The driver works with several other cameras in webcam mode (see the list
+below).
+
+Possible chipsets are : ZR36430 (ZR36430BGC) and
+maybe ZR36431, ZR36440, ZR36442...
+
+You can try the experience changing the vendor/product ID values (look
+at the source code).
+
+You can get these values by looking at /var/log/messages when you plug
+your camera, or by typing : cat /sys/kernel/debug/usb/devices.
+
+
+Install
+-------
+
+In order to use this driver, you must compile it with your kernel,
+with the following config options::
+
+    ./scripts/config -e USB
+    ./scripts/config -m MEDIA_SUPPORT
+    ./scripts/config -e MEDIA_USB_SUPPORT
+    ./scripts/config -e MEDIA_CAMERA_SUPPORT
+    ./scripts/config -m USB_ZR364XX
+
+Usage
+-----
+
+modprobe zr364xx debug=X mode=Y
+
+- debug      : set to 1 to enable verbose debug messages
+- mode       : 0 = 320x240, 1 = 160x120, 2 = 640x480
+
+You can then use the camera with V4L2 compatible applications, for
+example Ekiga.
+
+To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1M
+count=1

 - lens-focus: A phandle to the node of the focus lens controller.
 
-- rotation: The device, typically an image sensor, is not mounted upright,
-  but a number of degrees counter clockwise. Typical values are 0 and 180
-  (upside down).
-
+- rotation: The camera rotation is expressed as the angular difference in
+  degrees between two reference systems, one relative to the camera module, and
+  one defined on the external world scene to be captured when projected on the
+  image sensor pixel array.
+
+  A camera sensor has a 2-dimensional reference system 'Rc' defined by
+  its pixel array read-out order. The origin is set to the first pixel
+  being read out, the X-axis points along the column read-out direction
+  towards the last columns, and the Y-axis along the row read-out
+  direction towards the last row.
+
+  A typical example for a sensor with a 2592x1944 pixel array matrix
+  observed from the front is:
+
+              2591       X-axis          0

+
+  The external world scene reference system 'Rs' is a 2-dimensional
+  reference system on the focal plane of the camera module. The origin is
+  placed on the top-left corner of the visible scene, the X-axis points
+  towards the right, and the Y-axis points towards the bottom of the
+  scene. The top, bottom, left and right directions are intentionally not
+  defined and depend on the environment in which the camera is used.
+
+  A typical example of a (very common) picture of a shark swimming from
+  left to right, as seen from the camera, is:

+
+  When projected on the sensor's pixel array, the image and the associated
+  reference system 'Rs' are typically (but not always) inverted, due to
+  the camera module's lens optical inversion effect.
+
+  Assuming the above represented scene of the swimming shark, the lens
+  inversion projects the scene and its reference system onto the sensor
+  pixel array, seen from the front of the camera sensor, as follows:
+
+            Y-axis

+               0               X-axis
+
+  Note the shark being upside-down.
+
+  The resulting projected reference system is named 'Rp'.
+
+  The camera rotation property is then defined as the angular difference
+  in the counter-clockwise direction between the camera reference system
+  'Rc' and the projected scene reference system 'Rp'. It is expressed in
+  degrees as a number in the range [0, 360[.

+MIPI CSI-2
+==========
+
+CSI-2 is a data bus intended for transferring images from cameras to
+the host SoC. It is defined by the `MIPI alliance`_.
+
+.. _`MIPI alliance`: http://www.mipi.org/
+
+Media bus formats
+-----------------
+
+See :ref:`v4l2-mbus-pixelcode` for details on which media bus formats should
+be used for CSI-2 interfaces.
+
+Transmitter drivers
+-------------------
+
+CSI-2 transmitter, such as a sensor or a TV tuner, drivers need to
+provide the CSI-2 receiver with information on the CSI-2 bus
+configuration. These include the V4L2_CID_LINK_FREQ and
+V4L2_CID_PIXEL_RATE controls and
+(:c:type:`v4l2_subdev_video_ops`->s_stream() callback). These
+interface elements must be present on the sub-device represents the
+CSI-2 transmitter.
+
+The V4L2_CID_LINK_FREQ control is used to tell the receiver driver the
+frequency (and not the symbol rate) of the link. The
+V4L2_CID_PIXEL_RATE is may be used by the receiver to obtain the pixel
+rate the transmitter uses. The
+:c:type:`v4l2_subdev_video_ops`->s_stream() callback provides an
+ability to start and stop the stream.
+
+The value of the V4L2_CID_PIXEL_RATE is calculated as follows::
+
+	pixel_rate = link_freq * 2 * nr_of_lanes / bits_per_sample
+
+where
+
+.. list-table:: variables in pixel rate calculation
+   :header-rows: 1
+
+   * - variable or constant
+     - description
+   * - link_freq
+     - The value of the V4L2_CID_LINK_FREQ integer64 menu item.
+   * - nr_of_lanes
+     - Number of data lanes used on the CSI-2 link. This can
+       be obtained from the OF endpoint configuration.
+   * - 2
+     - Two bits are transferred per clock cycle per lane.
+   * - bits_per_sample
+     - Number of bits per sample.
+
+The transmitter drivers must, if possible, configure the CSI-2
+transmitter to *LP-11 mode* whenever the transmitter is powered on but
+not active, and maintain *LP-11 mode* until stream on. Only at stream
+on should the transmitter activate the clock on the clock lane and
+transition to *HS mode*.
+
+Some transmitters do this automatically but some have to be explicitly
+programmed to do so, and some are unable to do so altogether due to
+hardware constraints.
+
+Stopping the transmitter
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+A transmitter stops sending the stream of images as a result of
+calling the ``.s_stream()`` callback. Some transmitters may stop the
+stream at a frame boundary whereas others stop immediately,
+effectively leaving the current frame unfinished. The receiver driver
+should not make assumptions either way, but function properly in both
+cases.
+
+Receiver drivers
+----------------
+
+Before the receiver driver may enable the CSI-2 transmitter by using
+the :c:type:`v4l2_subdev_video_ops`->s_stream(), it must have powered
+the transmitter up by using the
+:c:type:`v4l2_subdev_core_ops`->s_power() callback. This may take
+place either indirectly by using :c:func:`v4l2_pipeline_pm_get` or
+directly.
+
+Formats
+-------
+
+The media bus pixel codes document parallel formats. Should the pixel data be
+transported over a serial bus, the media bus pixel code that describes a
+parallel format that transfers a sample on a single clock cycle is used.

+The bttv driver
+===============
+
+bttv and sound mini howto
+-------------------------
+
+There are a lot of different bt848/849/878/879 based boards available.
+Making video work often is not a big deal, because this is handled
+completely by the bt8xx chip, which is common on all boards.  But
+sound is handled in slightly different ways on each board.
+
+To handle the grabber boards correctly, there is a array tvcards[] in
+bttv-cards.c, which holds the information required for each board.
+Sound will work only, if the correct entry is used (for video it often
+makes no difference).  The bttv driver prints a line to the kernel
+log, telling which card type is used.  Like this one::
+
+	bttv0: model: BT848(Hauppauge old) [autodetected]
+
+You should verify this is correct.  If it isn't, you have to pass the
+correct board type as insmod argument, ``insmod bttv card=2`` for
+example.  The file :doc:`/admin-guide/media/bttv-cardlist` has a list
+of valid arguments for card.
+
+If your card isn't listed there, you might check the source code for
+new entries which are not listed yet.  If there isn't one for your
+card, you can check if one of the existing entries does work for you
+(just trial and error...).
+
+Some boards have an extra processor for sound to do stereo decoding
+and other nice features.  The msp34xx chips are used by Hauppauge for
+example.  If your board has one, you might have to load a helper
+module like ``msp3400`` to make sound work.  If there isn't one for the
+chip used on your board:  Bad luck.  Start writing a new one.  Well,
+you might want to check the video4linux mailing list archive first...
+
+Of course you need a correctly installed soundcard unless you have the
+speakers connected directly to the grabber board.  Hint: check the
+mixer settings too.  ALSA for example has everything muted by default.
+
+
+How sound works in detail
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Still doesn't work?  Looks like some driver hacking is required.
+Below is a do-it-yourself description for you.
+
+The bt8xx chips have 32 general purpose pins, and registers to control
+these pins.  One register is the output enable register
+(``BT848_GPIO_OUT_EN``), it says which pins are actively driven by the
+bt848 chip.  Another one is the data register (``BT848_GPIO_DATA``), where
+you can get/set the status if these pins.  They can be used for input
+and output.
+
+Most grabber board vendors use these pins to control an external chip
+which does the sound routing.  But every board is a little different.
+These pins are also used by some companies to drive remote control
+receiver chips.  Some boards use the i2c bus instead of the gpio pins
+to connect the mux chip.
+
+As mentioned above, there is a array which holds the required
+information for each known board.  You basically have to create a new
+line for your board.  The important fields are these two::
+
+  struct tvcard
+  {
+	[ ... ]
+	u32 gpiomask;
+	u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
+  };
+
+gpiomask specifies which pins are used to control the audio mux chip.
+The corresponding bits in the output enable register
+(``BT848_GPIO_OUT_EN``) will be set as these pins must be driven by the
+bt848 chip.
+
+The ``audiomux[]`` array holds the data values for the different inputs
+(i.e. which pins must be high/low for tuner/mute/...).  This will be
+written to the data register (``BT848_GPIO_DATA``) to switch the audio
+mux.
+
+
+What you have to do is figure out the correct values for gpiomask and
+the audiomux array.  If you have Windows and the drivers four your
+card installed, you might to check out if you can read these registers
+values used by the windows driver.  A tool to do this is available
+from http://btwincap.sourceforge.net/download.html.
+
+You might also dig around in the ``*.ini`` files of the Windows applications.
+You can have a look at the board to see which of the gpio pins are
+connected at all and then start trial-and-error ...
+
+
+Starting with release 0.7.41 bttv has a number of insmod options to
+make the gpio debugging easier:
+
+	=================	==============================================
+	bttv_gpio=0/1		enable/disable gpio debug messages
+	gpiomask=n		set the gpiomask value
+	audiomux=i,j,...	set the values of the audiomux array
+	audioall=a		set the values of the audiomux array (one
+				value for all array elements, useful to check
+				out which effect the particular value has).
+	=================	==============================================
+
+The messages printed with ``bttv_gpio=1`` look like this::
+
+	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
+
+	en  =	output _en_able register (BT848_GPIO_OUT_EN)
+	out =	_out_put bits of the data register (BT848_GPIO_DATA),
+		i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
+	in  = 	_in_put bits of the data register,
+		i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN

+The cpia2 driver
+================
+
+Authors: Peter Pregler <Peter_Pregler@email.com>,
+Scott J. Bertin <scottbertin@yahoo.com>, and
+Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
+this one was modelled from.
+
+
+Notes to developers
+~~~~~~~~~~~~~~~~~~~
+
+   - This is a driver version stripped of the 2.4 back compatibility
+     and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
+
+Programmer's overview of cpia2 driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a
+division of ST Microelectronics).  There are two versions.  The first is the
+STV0672, which is capable of up to 30 frames per second (fps) in frame sizes
+up to CIF, and 15 fps for VGA frames.  The STV0676 is an improved version,
+which can handle up to 30 fps VGA.  Both coprocessors can be attached to two
+CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor.  These will
+be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors.
+
+The two chipsets operate almost identically.  The core is an 8051 processor,
+running two different versions of firmware.  The 672 runs the VP4 video
+processor code, the 676 runs VP5.  There are a few differences in register
+mappings for the two chips.  In these cases, the symbols defined in the
+header files are marked with VP4 or VP5 as part of the symbol name.
+
+The cameras appear externally as three sets of registers. Setting register
+values is the only way to control the camera.  Some settings are
+interdependant, such as the sequence required to power up the camera. I will
+try to make note of all of these cases.
+
+The register sets are called blocks.  Block 0 is the system block.  This
+section is always powered on when the camera is plugged in.  It contains
+registers that control housekeeping functions such as powering up the video
+processor.  The video processor is the VP block.  These registers control
+how the video from the sensor is processed.  Examples are timing registers,
+user mode (vga, qvga), scaling, cropping, framerates, and so on.  The last
+block is the video compressor (VC).  The video stream sent from the camera is
+compressed as Motion JPEG (JPEGA).  The VC controls all of the compression
+parameters.  Looking at the file cpia2_registers.h, you can get a full view
+of these registers and the possible values for most of them.
+
+One or more registers can be set or read by sending a usb control message to
+the camera.  There are three modes for this.  Block mode requests a number
+of contiguous registers.  Random mode reads or writes random registers with
+a tuple structure containing address/value pairs.  The repeat mode is only
+used by VP4 to load a firmware patch.  It contains a starting address and
+a sequence of bytes to be written into a gpio port.

+==================
+
+Memory at cx2341x chips
+-----------------------
+
+This section describes the cx2341x memory map and documents some of the
+register space.
+
+.. note:: the memory long words are little-endian ('intel format').
+
+.. warning::
+
+	This information was figured out from searching through the memory
+	and registers, this information may not be correct and is certainly
+	not complete, and was not derived from anything more than searching
+	through the memory space with commands like:
+
+	.. code-block:: none
+
+		ivtvctl -O min=0x02000000,max=0x020000ff
+
+	So take this as is, I'm always searching for more stuff, it's a large
+	register space :-).
+
+Memory Map
+~~~~~~~~~~
+
+The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
+(Base Address Register 0). The addresses here are offsets relative to the
+address held in BAR0.

+
+
+How to call the firmware API
+----------------------------
+
+The preferred calling convention is known as the firmware mailbox. The
+mailboxes are basically a fixed length array that serves as the call-stack.
+
+Firmware mailboxes can be located by searching the encoder and decoder memory
+for a 16 byte signature. That signature will be located on a 256-byte boundary.
+
+Signature:
+
+.. code-block:: none
+
+	0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
+	0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
+
+The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
+reserved for API calls. The second 10 are used by the firmware for event
+notification.
+
+  ====== =================
+  Index  Name
+  ====== =================
+  0      Flags
+  1      Command
+  2      Return value
+  3      Timeout
+  4-19   Parameter/Result
+  ====== =================
+
+
+The flags are defined in the following table. The direction is from the
+perspective of the firmware.
+
+  ==== ========== ============================================
+  Bit  Direction  Purpose
+  ==== ========== ============================================
+  2    O          Firmware has processed the command.
+  1    I          Driver has finished setting the parameters.
+  0    I          Driver is using this mailbox.
+  ==== ========== ============================================
+
+The command is a 32-bit enumerator. The API specifics may be found in this
+chapter.
+
+The return value is a 32-bit enumerator. Only two values are currently defined:
+
+- 0=success
+- -1=command undefined.
+
+There are 16 parameters/results 32-bit fields. The driver populates these fields
+with values for all the parameters required by the call. The driver overwrites
+these fields with result values returned by the call.
+
+The timeout value protects the card from a hung driver thread. If the driver
+doesn't handle the completed call within the timeout specified, the firmware
+will reset that mailbox.
+
+To make an API call, the driver iterates over each mailbox looking for the
+first one available (bit 0 has been cleared). The driver sets that bit, fills
+in the command enumerator, the timeout value and any required parameters. The
+driver then sets the parameter ready bit (bit 1). The firmware scans the
+mailboxes for pending commands, processes them, sets the result code, populates
+the result value array with that call's return values and sets the call
+complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
+and clear all the flags. If the driver does not perform this task within the
+time set in the timeout register, the firmware will reset that mailbox.
+
+Event notifications are sent from the firmware to the host. The host tells the
+firmware which events it is interested in via an API call. That call tells the
+firmware which notification mailbox to use. The firmware signals the host via
+an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
+value and Timeout words are not used.
+

+Ends playback and clears all decoder buffers. If PTS is not zero,
+playback stops at specified PTS.
+
+Param[0]
+^^^^^^^^
+
+Display 0=last frame, 1=black
+
+.. note::
+
+	this takes effect immediately, so if you want to wait for a PTS,
+	then use '0', otherwise the screen goes to black at once.
+	You can call this later (even if there is no playback) with a 1 value
+	to set the screen to black.
+
+Param[1]

+	  desired speed.
+
+Param[0]
+^^^^^^^^

+	    31   Speed:
+		     '0' slow
+		     '1' fast
+
+.. note::
+
+	n is limited to 2. Anything higher does not result in
+	faster playback. Instead the host should start dropping frames.
+
+Param[1]
+^^^^^^^^
+
+Direction: 0=forward, 1=reverse

+Param[3]
+^^^^^^^^
+
+B frames per GOP (for reverse play only)
+
+.. note::
+
+	for reverse playback the Picture Mask should be set to I or I, P.

+
+This list has been worked out through trial and error. There will be mistakes
+and omissions. Some registers have no obvious effect so it's hard to say what
+they do, while others interact with each other, or require a certain load
+sequence. Horizontal filter setup is one example, with six registers working
+in unison and requiring a certain load sequence to correctly configure. The
+indexed colour palette is much easier to set at just two registers, but again
+it requires a certain load sequence.
+
+Some registers are fussy about what they are set to. Load in a bad value & the
+decoder will fail. A firmware reload will often recover, but sometimes a reset
+is required. For registers containing size information, setting them to 0 is
+generally a bad idea. For other control registers i.e. 2878, you'll only find
+out what values are bad when it hangs.

+	(2818), as this register actually clocks the data through for the first
+	five.
+
+	To correctly program set the filter, this whole procedure must be done 16
+	times. The actual register contents are copied from a lookup-table in the
+	firmware which contains 4 different filter settings.

+

+
+	Most of these registers either control horizontal scaling, or appear linked

+	correctly set the divider in Reg 2874.
+
+	To enlarge:
+		Reg 2854 = (source_width * 0x00200000) / destination_width
+		Reg 2874 = No divide
+
+	To reduce from full size down to half size:
+		Reg 2854 = (source_width/2 * 0x00200000) / destination width
+		Reg 2874 = Divide by 2
+
+	To reduce from half size down to quarter size:
+		Reg 2854 = (source_width/4 * 0x00200000) / destination width
+		Reg 2874 = Divide by 4
+
+	The result is always rounded up.

+
+	--------------------------------------------------------------------------------
+	2890
+	bits 0:11
+		Decoder output horizontal offset.
+
+	Horizontal offset moves the video image right. A small left shift is
+	possible, but it's better to use reg 2870 for that due to its greater
+	range.
+
+	NOTE: Video corruption will occur if video window is shifted off the right

+	--------------------------------------------------------------------------------
+	2898
+	bits 0:23
+		Decoder video window colour
+		Contains the colour (in yuv) used to fill the video window when the

+		1 = UV,Y
+
+	bit 29
+		Decoder second plane byte order
+		0 = Normal (UV)
+		1 = Swapped (VU)
+
+	In normal usage, the first plane is Y & the second plane is UV. Though the
+	order of the planes can be swapped, only the byte order of the second plane
+	can be swapped. This isn't much use for the Y plane, but can be useful for
+	the UV plane.

+
+	All output from the decoder & osd are disabled beyond this area. Decoder
+	output will simply go black outside of this region. If the osd tries to
+	exceed this area it will become corrupt.
+	--------------------------------------------------------------------------------
+	28A4
+	bits 0:11

+	bits 0:31
+		Decoder vertical Y alias register 2
+	---------------
+	2908
+	bits 0:31
+		Decoder vertical Y alias trigger
+
+	These three registers control the vertical aliasing filter for the Y plane.
+	Operation is similar to the horizontal Y filter (2804). The only real
+	difference is that there are only two registers to set before accessing
+	the trigger register (2908). As for the horizontal filter, the values are
+	taken from a lookup table in the firmware, and the procedure must be

+
+	When the bits-per-pixel is set to 8, the colour mode is ignored and
+	assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
+	is honoured, and when using a colour depth that requires fewer bytes than
+	allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
+	index colour, there are 3 padding bytes per pixel. It's also possible to
+	select 16bpp with a 32 bit colour mode. This results in the pixel width
+	being doubled, but the color key will not work as expected in this mode.
+
+	Colour key is as it suggests. You designate a colour which will become
+	completely transparent. When using 565, 555 or 444 colour modes, the
+	colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
+
+	Local alpha works differently depending on the colour mode. For 32bpp & 8
+	bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
+	transparent and 255 being solid. For the 16bpp modes 555 & 444, the unused
+	bit(s) act as a simple transparency switch, with 0 being solid & 1 being
+	fully transparent. There is no local alpha support for 16bit 565.
+
+	Global alpha is a 256 step transparency that applies to the entire osd,
+	with 0 being transparent & 255 being solid.
+
+	It's possible to combine colour key, local alpha & global alpha.

+The cx231xx DMA engine
+----------------------
+
+
+This page describes the structures and procedures used by the cx2341x DMA
+engine.
+
+Introduction
+~~~~~~~~~~~~
+
+The cx2341x PCI interface is busmaster capable. This means it has a DMA
+engine to efficiently transfer large volumes of data between the card and main
+memory without requiring help from a CPU. Like most hardware, it must operate
+on contiguous physical memory. This is difficult to come by in large quantities
+on virtual memory machines.
+
+Therefore, it also supports a technique called "scatter-gather". The card can
+transfer multiple buffers in one operation. Instead of allocating one large
+contiguous buffer, the driver can allocate several smaller buffers.
+
+In practice, I've seen the average transfer to be roughly 80K, but transfers
+above 128K were not uncommon, particularly at startup. The 128K figure is
+important, because that is the largest block that the kernel can normally
+allocate. Even still, 128K blocks are hard to come by, so the driver writer is
+urged to choose a smaller block size and learn the scatter-gather technique.
+
+Mailbox #10 is reserved for DMA transfer information.
+
+Note: the hardware expects little-endian data ('intel format').
+
+Flow
+~~~~
+
+This section describes, in general, the order of events when handling DMA
+transfers. Detailed information follows this section.
+
+- The card raises the Encoder interrupt.
+- The driver reads the transfer type, offset and size from Mailbox #10.
+- The driver constructs the scatter-gather array from enough free dma buffers
+  to cover the size.
+- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
+- The card raises the DMA Complete interrupt.
+- The driver checks the DMA status register for any errors.
+- The driver post-processes the newly transferred buffers.
+
+NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
+simultaneously. (End of the last, start of the next, etc.)
+
+Mailbox #10
+~~~~~~~~~~~
+
+The Flags, Command, Return Value and Timeout fields are ignored.
+
+- Name:       Mailbox #10
+- Results[0]: Type: 0: MPEG.
+- Results[1]: Offset: The position relative to the card's memory space.
+- Results[2]: Size: The exact number of bytes to transfer.
+
+My speculation is that since the StartCapture API has a capture type of "RAW"
+available, that the type field will have other values that correspond to YUV
+and PCM data.
+
+Scatter-Gather Array
+~~~~~~~~~~~~~~~~~~~~
+
+The scatter-gather array is a contiguously allocated block of memory that
+tells the card the source and destination of each data-block to transfer.
+Card "addresses" are derived from the offset supplied by Mailbox #10. Host
+addresses are the physical memory location of the target DMA buffer.
+
+Each S-G array element is a struct of three 32-bit words. The first word is
+the source address, the second is the destination address. Both take up the
+entire 32 bits. The lowest 18 bits of the third word is the transfer byte
+count. The high-bit of the third word is the "last" flag. The last-flag tells
+the card to raise the DMA_DONE interrupt. From hard personal experience, if
+you forget to set this bit, the card will still "work" but the stream will
+most likely get corrupted.
+
+The transfer count must be a multiple of 256. Therefore, the driver will need
+to track how much data in the target buffer is valid and deal with it
+accordingly.
+
+Array Element:
+
+- 32-bit Source Address
+- 32-bit Destination Address
+- 14-bit reserved (high bit is the last flag)
+- 18-bit byte count
+
+DMA Transfer Status
+~~~~~~~~~~~~~~~~~~~
+
+Register 0x0004 holds the DMA Transfer Status:
+
+- bit 0:   read completed
+- bit 1:   write completed
+- bit 2:   DMA read error
+- bit 3:   DMA write error
+- bit 4:   Scatter-Gather array error

+
+Hauppauge WinTV cx88 IR information
+-----------------------------------
+
+The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
+
+====== ======== =================================================
+GPIO0  GPIO1
+====== ======== =================================================
+  0        0    TV Audio
+  1        0    FM radio
+  0        1    Line-In
+  1        1    Mono tuner bypass or CD passthru (tuner specific)
+====== ======== =================================================
+
+GPIO 16(I believe) is tied to the IR port (if present).
+
+
+From the data sheet:
+
+- Register 24'h20004  PCI Interrupt Status
+
+ - bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
+ - gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+- Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+  compat remote)
+- set register 0x35C050 to  0xa80a80
+- enable sampling
+- set register 0x35C054 to 0x5
+- enable the IRQ bit 18 in the interrupt mask register (and
+  provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is received.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well.  Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.
+

+==================

+Author Gerd Hoffmann
+
+
+Card Variations:
+----------------
+
+Cards can use either of these two crystals (xtal):
+
+- 32.11 MHz -> .audio_clock=0x187de7
+- 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
+
+Some details about 30/34/35:
+
+- saa7130 - low-price chip, doesn't have mute, that is why all those
+  cards should have .mute field defined in their tuner structure.
+
+- saa7134 - usual chip
+
+- saa7133/35 - saa7135 is probably a marketing decision, since all those
+  chips identifies itself as 33 on pci.

+V4L2 sub-devices
+----------------
+
+Many drivers need to communicate with sub-devices. These devices can do all
+sort of tasks, but most commonly they handle audio and/or video muxing,
+encoding or decoding. For webcams common sub-devices are sensors and camera
+controllers.
+
+Usually these are I2C devices, but not necessarily. In order to provide the
+driver with a consistent interface to these sub-devices the
+:c:type:`v4l2_subdev` struct (v4l2-subdev.h) was created.
+
+Each sub-device driver must have a :c:type:`v4l2_subdev` struct. This struct
+can be stand-alone for simple sub-devices or it might be embedded in a larger
+struct if more state information needs to be stored. Usually there is a
+low-level device struct (e.g. ``i2c_client``) that contains the device data as
+setup by the kernel. It is recommended to store that pointer in the private
+data of :c:type:`v4l2_subdev` using :c:func:`v4l2_set_subdevdata`. That makes
+it easy to go from a :c:type:`v4l2_subdev` to the actual low-level bus-specific
+device data.
+
+You also need a way to go from the low-level struct to :c:type:`v4l2_subdev`.
+For the common i2c_client struct the i2c_set_clientdata() call is used to store
+a :c:type:`v4l2_subdev` pointer, for other buses you may have to use other
+methods.
+
+Bridges might also need to store per-subdev private data, such as a pointer to
+bridge-specific per-subdev private data. The :c:type:`v4l2_subdev` structure
+provides host private data for that purpose that can be accessed with
+:c:func:`v4l2_get_subdev_hostdata` and :c:func:`v4l2_set_subdev_hostdata`.
+
+From the bridge driver perspective, you load the sub-device module and somehow
+obtain the :c:type:`v4l2_subdev` pointer. For i2c devices this is easy: you call
+``i2c_get_clientdata()``. For other buses something similar needs to be done.
+Helper functions exists for sub-devices on an I2C bus that do most of this
+tricky work for you.
+
+Each :c:type:`v4l2_subdev` contains function pointers that sub-device drivers
+can implement (or leave ``NULL`` if it is not applicable). Since sub-devices can
+do so many different things and you do not want to end up with a huge ops struct
+of which only a handful of ops are commonly implemented, the function pointers
+are sorted according to category and each category has its own ops struct.
+
+The top-level ops struct contains pointers to the category ops structs, which
+may be NULL if the subdev driver does not support anything from that category.
+
+It looks like this:
+
+.. code-block:: c
+
+	struct v4l2_subdev_core_ops {
+		int (*log_status)(struct v4l2_subdev *sd);
+		int (*init)(struct v4l2_subdev *sd, u32 val);
+		...
+	};
+
+	struct v4l2_subdev_tuner_ops {
+		...
+	};
+
+	struct v4l2_subdev_audio_ops {
+		...
+	};
+
+	struct v4l2_subdev_video_ops {
+		...
+	};
+
+	struct v4l2_subdev_pad_ops {
+		...
+	};
+
+	struct v4l2_subdev_ops {
+		const struct v4l2_subdev_core_ops  *core;
+		const struct v4l2_subdev_tuner_ops *tuner;
+		const struct v4l2_subdev_audio_ops *audio;
+		const struct v4l2_subdev_video_ops *video;
+		const struct v4l2_subdev_pad_ops *video;
+	};
+
+The core ops are common to all subdevs, the other categories are implemented
+depending on the sub-device. E.g. a video device is unlikely to support the
+audio ops and vice versa.
+
+This setup limits the number of function pointers while still making it easy
+to add new ops and categories.
+
+A sub-device driver initializes the :c:type:`v4l2_subdev` struct using:
+
+	:c:func:`v4l2_subdev_init <v4l2_subdev_init>`
+	(:c:type:`sd <v4l2_subdev>`, &\ :c:type:`ops <v4l2_subdev_ops>`).
+
+
+Afterwards you need to initialize :c:type:`sd <v4l2_subdev>`->name with a
+unique name and set the module owner. This is done for you if you use the
+i2c helper functions.
+
+If integration with the media framework is needed, you must initialize the
+:c:type:`media_entity` struct embedded in the :c:type:`v4l2_subdev` struct
+(entity field) by calling :c:func:`media_entity_pads_init`, if the entity has
+pads:
+
+.. code-block:: c
+
+	struct media_pad *pads = &my_sd->pads;
+	int err;
+
+	err = media_entity_pads_init(&sd->entity, npads, pads);
+
+The pads array must have been previously initialized. There is no need to
+manually set the struct :c:type:`media_entity` function and name fields, but the
+revision field must be initialized if needed.
+
+A reference to the entity will be automatically acquired/released when the
+subdev device node (if any) is opened/closed.
+
+Don't forget to cleanup the media entity before the sub-device is destroyed:
+
+.. code-block:: c
+
+	media_entity_cleanup(&sd->entity);
+
+If the subdev driver intends to process video and integrate with the media
+framework, it must implement format related functionality using
+:c:type:`v4l2_subdev_pad_ops` instead of :c:type:`v4l2_subdev_video_ops`.
+
+In that case, the subdev driver may set the link_validate field to provide
+its own link validation function. The link validation function is called for
+every link in the pipeline where both of the ends of the links are V4L2
+sub-devices. The driver is still responsible for validating the correctness
+of the format configuration between sub-devices and video nodes.
+
+If link_validate op is not set, the default function
+:c:func:`v4l2_subdev_link_validate_default` is used instead. This function
+ensures that width, height and the media bus pixel code are equal on both source
+and sink of the link. Subdev drivers are also free to use this function to
+perform the checks mentioned above in addition to their own checks.
+
+There are currently two ways to register subdevices with the V4L2 core. The
+first (traditional) possibility is to have subdevices registered by bridge
+drivers. This can be done when the bridge driver has the complete information
+about subdevices connected to it and knows exactly when to register them. This
+is typically the case for internal subdevices, like video data processing units
+within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected
+to SoCs, which pass information about them to bridge drivers, usually in their
+platform data.
+
+There are however also situations where subdevices have to be registered
+asynchronously to bridge devices. An example of such a configuration is a Device
+Tree based system where information about subdevices is made available to the
+system independently from the bridge devices, e.g. when subdevices are defined
+in DT as I2C device nodes. The API used in this second case is described further
+below.
+
+Using one or the other registration method only affects the probing process, the
+run-time bridge-subdevice interaction is in both cases the same.
+
+In the synchronous case a device (bridge) driver needs to register the
+:c:type:`v4l2_subdev` with the v4l2_device:
+
+	:c:func:`v4l2_device_register_subdev <v4l2_device_register_subdev>`
+	(:c:type:`v4l2_dev <v4l2_device>`, :c:type:`sd <v4l2_subdev>`).
+
+This can fail if the subdev module disappeared before it could be registered.
+After this function was called successfully the subdev->dev field points to
+the :c:type:`v4l2_device`.
+
+If the v4l2_device parent device has a non-NULL mdev field, the sub-device
+entity will be automatically registered with the media device.
+
+You can unregister a sub-device using:
+
+	:c:func:`v4l2_device_unregister_subdev <v4l2_device_unregister_subdev>`
+	(:c:type:`sd <v4l2_subdev>`).
+
+
+Afterwards the subdev module can be unloaded and
+:c:type:`sd <v4l2_subdev>`->dev == ``NULL``.
+
+You can call an ops function either directly:
+
+.. code-block:: c
+
+	err = sd->ops->core->g_std(sd, &norm);
+
+but it is better and easier to use this macro:
+
+.. code-block:: c
+
+	err = v4l2_subdev_call(sd, core, g_std, &norm);
+
+The macro will to the right ``NULL`` pointer checks and returns ``-ENODEV``
+if :c:type:`sd <v4l2_subdev>` is ``NULL``, ``-ENOIOCTLCMD`` if either
+:c:type:`sd <v4l2_subdev>`->core or :c:type:`sd <v4l2_subdev>`->core->g_std is ``NULL``, or the actual result of the
+:c:type:`sd <v4l2_subdev>`->ops->core->g_std ops.
+
+It is also possible to call all or a subset of the sub-devices:
+
+.. code-block:: c
+
+	v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
+
+Any subdev that does not support this ops is skipped and error results are
+ignored. If you want to check for errors use this:
+
+.. code-block:: c
+
+	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
+
+Any error except ``-ENOIOCTLCMD`` will exit the loop with that error. If no
+errors (except ``-ENOIOCTLCMD``) occurred, then 0 is returned.
+
+The second argument to both calls is a group ID. If 0, then all subdevs are
+called. If non-zero, then only those whose group ID match that value will
+be called. Before a bridge driver registers a subdev it can set
+:c:type:`sd <v4l2_subdev>`->grp_id to whatever value it wants (it's 0 by
+default). This value is owned by the bridge driver and the sub-device driver
+will never modify or use it.
+
+The group ID gives the bridge driver more control how callbacks are called.
+For example, there may be multiple audio chips on a board, each capable of
+changing the volume. But usually only one will actually be used when the
+user want to change the volume. You can set the group ID for that subdev to
+e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
+``v4l2_device_call_all()``. That ensures that it will only go to the subdev
+that needs it.
+
+If the sub-device needs to notify its v4l2_device parent of an event, then
+it can call ``v4l2_subdev_notify(sd, notification, arg)``. This macro checks
+whether there is a ``notify()`` callback defined and returns ``-ENODEV`` if not.
+Otherwise the result of the ``notify()`` call is returned.
+
+The advantage of using :c:type:`v4l2_subdev` is that it is a generic struct and
+does not contain any knowledge about the underlying hardware. So a driver might
+contain several subdevs that use an I2C bus, but also a subdev that is
+controlled through GPIO pins. This distinction is only relevant when setting
+up the device, but once the subdev is registered it is completely transparent.
+
+In the asynchronous case subdevice probing can be invoked independently of the
+bridge driver availability. The subdevice driver then has to verify whether all
+the requirements for a successful probing are satisfied. This can include a
+check for a master clock availability. If any of the conditions aren't satisfied
+the driver might decide to return ``-EPROBE_DEFER`` to request further reprobing
+attempts. Once all conditions are met the subdevice shall be registered using
+the :c:func:`v4l2_async_register_subdev` function. Unregistration is
+performed using the :c:func:`v4l2_async_unregister_subdev` call. Subdevices
+registered this way are stored in a global list of subdevices, ready to be
+picked up by bridge drivers.
+
+Bridge drivers in turn have to register a notifier object. This is
+performed using the :c:func:`v4l2_async_notifier_register` call. To
+unregister the notifier the driver has to call
+:c:func:`v4l2_async_notifier_unregister`. The former of the two functions
+takes two arguments: a pointer to struct :c:type:`v4l2_device` and a
+pointer to struct :c:type:`v4l2_async_notifier`.
+
+Before registering the notifier, bridge drivers must do two things:
+first, the notifier must be initialized using the
+:c:func:`v4l2_async_notifier_init`. Second, bridge drivers can then
+begin to form a list of subdevice descriptors that the bridge device
+needs for its operation. Subdevice descriptors are added to the notifier
+using the :c:func:`v4l2_async_notifier_add_subdev` call. This function
+takes two arguments: a pointer to struct :c:type:`v4l2_async_notifier`,
+and a pointer to the subdevice descripter, which is of type struct
+:c:type:`v4l2_async_subdev`.
+
+The V4L2 core will then use these descriptors to match asynchronously
+registered subdevices to them. If a match is detected the ``.bound()``
+notifier callback is called. After all subdevices have been located the
+.complete() callback is called. When a subdevice is removed from the
+system the .unbind() method is called. All three callbacks are optional.
+
+V4L2 sub-device userspace API
+-----------------------------
+
+Bridge drivers traditionally expose one or multiple video nodes to userspace,
+and control subdevices through the :c:type:`v4l2_subdev_ops` operations in
+response to video node operations. This hides the complexity of the underlying
+hardware from applications. For complex devices, finer-grained control of the
+device than what the video nodes offer may be required. In those cases, bridge
+drivers that implement :ref:`the media controller API <media_controller>` may
+opt for making the subdevice operations directly accessible from userpace.
+
+Device nodes named ``v4l-subdev``\ *X* can be created in ``/dev`` to access
+sub-devices directly. If a sub-device supports direct userspace configuration
+it must set the ``V4L2_SUBDEV_FL_HAS_DEVNODE`` flag before being registered.
+
+After registering sub-devices, the :c:type:`v4l2_device` driver can create
+device nodes for all registered sub-devices marked with
+``V4L2_SUBDEV_FL_HAS_DEVNODE`` by calling
+:c:func:`v4l2_device_register_subdev_nodes`. Those device nodes will be
+automatically removed when sub-devices are unregistered.
+
+The device node handles a subset of the V4L2 API.
+
+``VIDIOC_QUERYCTRL``,
+``VIDIOC_QUERYMENU``,
+``VIDIOC_G_CTRL``,
+``VIDIOC_S_CTRL``,
+``VIDIOC_G_EXT_CTRLS``,
+``VIDIOC_S_EXT_CTRLS`` and
+``VIDIOC_TRY_EXT_CTRLS``:
+
+	The controls ioctls are identical to the ones defined in V4L2. They
+	behave identically, with the only exception that they deal only with
+	controls implemented in the sub-device. Depending on the driver, those
+	controls can be also be accessed through one (or several) V4L2 device
+	nodes.
+
+``VIDIOC_DQEVENT``,
+``VIDIOC_SUBSCRIBE_EVENT`` and
+``VIDIOC_UNSUBSCRIBE_EVENT``
+
+	The events ioctls are identical to the ones defined in V4L2. They
+	behave identically, with the only exception that they deal only with
+	events generated by the sub-device. Depending on the driver, those
+	events can also be reported by one (or several) V4L2 device nodes.
+
+	Sub-device drivers that want to use events need to set the
+	``V4L2_SUBDEV_USES_EVENTS`` :c:type:`v4l2_subdev`.flags and initialize
+	:c:type:`v4l2_subdev`.nevents to events queue depth before registering
+	the sub-device. After registration events can be queued as usual on the
+	:c:type:`v4l2_subdev`.devnode device node.
+
+	To properly support events, the ``poll()`` file operation is also
+	implemented.
+
+Private ioctls
+
+	All ioctls not in the above list are passed directly to the sub-device
+	driver through the core::ioctl operation.
+
+Read-only sub-device userspace API
+----------------------------------
+
+Bridge drivers that control their connected subdevices through direct calls to
+the kernel API realized by :c:type:`v4l2_subdev_ops` structure do not usually
+want userspace to be able to change the same parameters through the subdevice
+device node and thus do not usually register any.
+
+It is sometimes useful to report to userspace the current subdevice
+configuration through a read-only API, that does not permit applications to
+change to the device parameters but allows interfacing to the subdevice device
+node to inspect them.
+
+For instance, to implement cameras based on computational photography, userspace
+needs to know the detailed camera sensor configuration (in terms of skipping,
+binning, cropping and scaling) for each supported output resolution. To support
+such use cases, bridge drivers may expose the subdevice operations to userspace
+through a read-only API.
+
+To create a read-only device node for all the subdevices registered with the
+``V4L2_SUBDEV_FL_HAS_DEVNODE`` set, the :c:type:`v4l2_device` driver should call
+:c:func:`v4l2_device_register_ro_subdev_nodes`.
+
+Access to the following ioctls for userspace applications is restricted on
+sub-device device nodes registered with
+:c:func:`v4l2_device_register_ro_subdev_nodes`.
+
+``VIDIOC_SUBDEV_S_FMT``,
+``VIDIOC_SUBDEV_S_CROP``,
+``VIDIOC_SUBDEV_S_SELECTION``:
+
+	These ioctls are only allowed on a read-only subdevice device node
+	for the :ref:`V4L2_SUBDEV_FORMAT_TRY <v4l2-subdev-format-whence>`
+	formats and selection rectangles.
+
+``VIDIOC_SUBDEV_S_FRAME_INTERVAL``,
+``VIDIOC_SUBDEV_S_DV_TIMINGS``,
+``VIDIOC_SUBDEV_S_STD``:
+
+	These ioctls are not allowed on a read-only subdevice node.
+
+In case the ioctl is not allowed, or the format to modify is set to
+``V4L2_SUBDEV_FORMAT_ACTIVE``, the core returns a negative error code and
+the errno variable is set to ``-EPERM``.
+
+I2C sub-device drivers
+----------------------
+
+Since these drivers are so common, special helper functions are available to
+ease the use of these drivers (``v4l2-common.h``).
+
+The recommended method of adding :c:type:`v4l2_subdev` support to an I2C driver
+is to embed the :c:type:`v4l2_subdev` struct into the state struct that is
+created for each I2C device instance. Very simple devices have no state
+struct and in that case you can just create a :c:type:`v4l2_subdev` directly.
+
+A typical state struct would look like this (where 'chipname' is replaced by
+the name of the chip):
+
+.. code-block:: c
+
+	struct chipname_state {
+		struct v4l2_subdev sd;
+		...  /* additional state fields */
+	};
+
+Initialize the :c:type:`v4l2_subdev` struct as follows:
+
+.. code-block:: c
+
+	v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
+
+This function will fill in all the fields of :c:type:`v4l2_subdev` ensure that
+the :c:type:`v4l2_subdev` and i2c_client both point to one another.
+
+You should also add a helper inline function to go from a :c:type:`v4l2_subdev`
+pointer to a chipname_state struct:
+
+.. code-block:: c
+
+	static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
+	{
+		return container_of(sd, struct chipname_state, sd);
+	}
+
+Use this to go from the :c:type:`v4l2_subdev` struct to the ``i2c_client``
+struct:
+
+.. code-block:: c
+
+	struct i2c_client *client = v4l2_get_subdevdata(sd);
+
+And this to go from an ``i2c_client`` to a :c:type:`v4l2_subdev` struct:
+
+.. code-block:: c
+
+	struct v4l2_subdev *sd = i2c_get_clientdata(client);
+
+Make sure to call
+:c:func:`v4l2_device_unregister_subdev`\ (:c:type:`sd <v4l2_subdev>`)
+when the ``remove()`` callback is called. This will unregister the sub-device
+from the bridge driver. It is safe to call this even if the sub-device was
+never registered.
+
+You need to do this because when the bridge driver destroys the i2c adapter
+the ``remove()`` callbacks are called of the i2c devices on that adapter.
+After that the corresponding v4l2_subdev structures are invalid, so they
+have to be unregistered first. Calling
+:c:func:`v4l2_device_unregister_subdev`\ (:c:type:`sd <v4l2_subdev>`)
+from the ``remove()`` callback ensures that this is always done correctly.
+
+
+The bridge driver also has some helper functions it can use:
+
+.. code-block:: c
+
+	struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter,
+					"module_foo", "chipid", 0x36, NULL);
+
+This loads the given module (can be ``NULL`` if no module needs to be loaded)
+and calls :c:func:`i2c_new_device` with the given ``i2c_adapter`` and
+chip/address arguments. If all goes well, then it registers the subdev with
+the v4l2_device.
+
+You can also use the last argument of :c:func:`v4l2_i2c_new_subdev` to pass
+an array of possible I2C addresses that it should probe. These probe addresses
+are only used if the previous argument is 0. A non-zero argument means that you
+know the exact i2c address so in that case no probing will take place.
+
+Both functions return ``NULL`` if something went wrong.
+
+Note that the chipid you pass to :c:func:`v4l2_i2c_new_subdev` is usually
+the same as the module name. It allows you to specify a chip variant, e.g.
+"saa7114" or "saa7115". In general though the i2c driver autodetects this.
+The use of chipid is something that needs to be looked at more closely at a
+later date. It differs between i2c drivers and as such can be confusing.
+To see which chip variants are supported you can look in the i2c driver code
+for the i2c_device_id table. This lists all the possibilities.
+
+There are one more helper function:
+
+:c:func:`v4l2_i2c_new_subdev_board` uses an :c:type:`i2c_board_info` struct
+which is passed to the i2c driver and replaces the irq, platform_data and addr
+arguments.
+
+If the subdev supports the s_config core ops, then that op is called with
+the irq and platform_data arguments after the subdev was setup.
+
+The :c:func:`v4l2_i2c_new_subdev` function will call
+:c:func:`v4l2_i2c_new_subdev_board`, internally filling a
+:c:type:`i2c_board_info` structure using the ``client_type`` and the
+``addr`` to fill it.

+Videobuf Framework
+==================
+
+Author: Jonathan Corbet <corbet@lwn.net>
+
+Current as of 2.6.33
+
+.. note::
+
+   The videobuf framework was deprecated in favor of videobuf2. Shouldn't
+   be used on new drivers.
+
+Introduction
+------------
+
+The videobuf layer functions as a sort of glue layer between a V4L2 driver
+and user space.  It handles the allocation and management of buffers for
+the storage of video frames.  There is a set of functions which can be used
+to implement many of the standard POSIX I/O system calls, including read(),
+poll(), and, happily, mmap().  Another set of functions can be used to
+implement the bulk of the V4L2 ioctl() calls related to streaming I/O,
+including buffer allocation, queueing and dequeueing, and streaming
+control.  Using videobuf imposes a few design decisions on the driver
+author, but the payback comes in the form of reduced code in the driver and
+a consistent implementation of the V4L2 user-space API.
+
+Buffer types
+------------
+
+Not all video devices use the same kind of buffers.  In fact, there are (at
+least) three common variations:
+
+ - Buffers which are scattered in both the physical and (kernel) virtual
+   address spaces.  (Almost) all user-space buffers are like this, but it
+   makes great sense to allocate kernel-space buffers this way as well when
+   it is possible.  Unfortunately, it is not always possible; working with
+   this kind of buffer normally requires hardware which can do
+   scatter/gather DMA operations.
+
+ - Buffers which are physically scattered, but which are virtually
+   contiguous; buffers allocated with vmalloc(), in other words.  These
+   buffers are just as hard to use for DMA operations, but they can be
+   useful in situations where DMA is not available but virtually-contiguous
+   buffers are convenient.
+
+ - Buffers which are physically contiguous.  Allocation of this kind of
+   buffer can be unreliable on fragmented systems, but simpler DMA
+   controllers cannot deal with anything else.
+
+Videobuf can work with all three types of buffers, but the driver author
+must pick one at the outset and design the driver around that decision.
+
+[It's worth noting that there's a fourth kind of buffer: "overlay" buffers
+which are located within the system's video memory.  The overlay
+functionality is considered to be deprecated for most use, but it still
+shows up occasionally in system-on-chip drivers where the performance
+benefits merit the use of this technique.  Overlay buffers can be handled
+as a form of scattered buffer, but there are very few implementations in
+the kernel and a description of this technique is currently beyond the
+scope of this document.]
+
+Data structures, callbacks, and initialization
+----------------------------------------------
+
+Depending on which type of buffers are being used, the driver should
+include one of the following files:
+
+.. code-block:: none
+
+    <media/videobuf-dma-sg.h>		/* Physically scattered */
+    <media/videobuf-vmalloc.h>		/* vmalloc() buffers	*/
+    <media/videobuf-dma-contig.h>	/* Physically contiguous */
+
+The driver's data structure describing a V4L2 device should include a
+struct videobuf_queue instance for the management of the buffer queue,
+along with a list_head for the queue of available buffers.  There will also
+need to be an interrupt-safe spinlock which is used to protect (at least)
+the queue.
+
+The next step is to write four simple callbacks to help videobuf deal with
+the management of buffers:
+
+.. code-block:: none
+
+    struct videobuf_queue_ops {
+	int (*buf_setup)(struct videobuf_queue *q,
+			 unsigned int *count, unsigned int *size);
+	int (*buf_prepare)(struct videobuf_queue *q,
+			   struct videobuf_buffer *vb,
+			   enum v4l2_field field);
+	void (*buf_queue)(struct videobuf_queue *q,
+			  struct videobuf_buffer *vb);
+	void (*buf_release)(struct videobuf_queue *q,
+			    struct videobuf_buffer *vb);
+    };
+
+buf_setup() is called early in the I/O process, when streaming is being
+initiated; its purpose is to tell videobuf about the I/O stream.  The count
+parameter will be a suggested number of buffers to use; the driver should
+check it for rationality and adjust it if need be.  As a practical rule, a
+minimum of two buffers are needed for proper streaming, and there is
+usually a maximum (which cannot exceed 32) which makes sense for each
+device.  The size parameter should be set to the expected (maximum) size
+for each frame of data.
+
+Each buffer (in the form of a struct videobuf_buffer pointer) will be
+passed to buf_prepare(), which should set the buffer's size, width, height,
+and field fields properly.  If the buffer's state field is
+VIDEOBUF_NEEDS_INIT, the driver should pass it to:
+
+.. code-block:: none
+
+    int videobuf_iolock(struct videobuf_queue* q, struct videobuf_buffer *vb,
+			struct v4l2_framebuffer *fbuf);
+
+Among other things, this call will usually allocate memory for the buffer.
+Finally, the buf_prepare() function should set the buffer's state to
+VIDEOBUF_PREPARED.
+
+When a buffer is queued for I/O, it is passed to buf_queue(), which should
+put it onto the driver's list of available buffers and set its state to
+VIDEOBUF_QUEUED.  Note that this function is called with the queue spinlock
+held; if it tries to acquire it as well things will come to a screeching
+halt.  Yes, this is the voice of experience.  Note also that videobuf may
+wait on the first buffer in the queue; placing other buffers in front of it
+could again gum up the works.  So use list_add_tail() to enqueue buffers.
+
+Finally, buf_release() is called when a buffer is no longer intended to be
+used.  The driver should ensure that there is no I/O active on the buffer,
+then pass it to the appropriate free routine(s):
+
+.. code-block:: none
+
+    /* Scatter/gather drivers */
+    int videobuf_dma_unmap(struct videobuf_queue *q,
+			   struct videobuf_dmabuf *dma);
+    int videobuf_dma_free(struct videobuf_dmabuf *dma);
+
+    /* vmalloc drivers */
+    void videobuf_vmalloc_free (struct videobuf_buffer *buf);
+
+    /* Contiguous drivers */
+    void videobuf_dma_contig_free(struct videobuf_queue *q,
+				  struct videobuf_buffer *buf);
+
+One way to ensure that a buffer is no longer under I/O is to pass it to:
+
+.. code-block:: none
+
+    int videobuf_waiton(struct videobuf_buffer *vb, int non_blocking, int intr);
+
+Here, vb is the buffer, non_blocking indicates whether non-blocking I/O
+should be used (it should be zero in the buf_release() case), and intr
+controls whether an interruptible wait is used.
+
+File operations
+---------------
+
+At this point, much of the work is done; much of the rest is slipping
+videobuf calls into the implementation of the other driver callbacks.  The
+first step is in the open() function, which must initialize the
+videobuf queue.  The function to use depends on the type of buffer used:
+
+.. code-block:: none
+
+    void videobuf_queue_sg_init(struct videobuf_queue *q,
+				struct videobuf_queue_ops *ops,
+				struct device *dev,
+				spinlock_t *irqlock,
+				enum v4l2_buf_type type,
+				enum v4l2_field field,
+				unsigned int msize,
+				void *priv);
+
+    void videobuf_queue_vmalloc_init(struct videobuf_queue *q,
+				struct videobuf_queue_ops *ops,
+				struct device *dev,
+				spinlock_t *irqlock,
+				enum v4l2_buf_type type,
+				enum v4l2_field field,
+				unsigned int msize,
+				void *priv);
+
+    void videobuf_queue_dma_contig_init(struct videobuf_queue *q,
+				       struct videobuf_queue_ops *ops,
+				       struct device *dev,
+				       spinlock_t *irqlock,
+				       enum v4l2_buf_type type,
+				       enum v4l2_field field,
+				       unsigned int msize,
+				       void *priv);
+
+In each case, the parameters are the same: q is the queue structure for the
+device, ops is the set of callbacks as described above, dev is the device
+structure for this video device, irqlock is an interrupt-safe spinlock to
+protect access to the data structures, type is the buffer type used by the
+device (cameras will use V4L2_BUF_TYPE_VIDEO_CAPTURE, for example), field
+describes which field is being captured (often V4L2_FIELD_NONE for
+progressive devices), msize is the size of any containing structure used
+around struct videobuf_buffer, and priv is a private data pointer which
+shows up in the priv_data field of struct videobuf_queue.  Note that these
+are void functions which, evidently, are immune to failure.
+
+V4L2 capture drivers can be written to support either of two APIs: the
+read() system call and the rather more complicated streaming mechanism.  As
+a general rule, it is necessary to support both to ensure that all
+applications have a chance of working with the device.  Videobuf makes it
+easy to do that with the same code.  To implement read(), the driver need
+only make a call to one of:
+
+.. code-block:: none
+
+    ssize_t videobuf_read_one(struct videobuf_queue *q,
+			      char __user *data, size_t count,
+			      loff_t *ppos, int nonblocking);
+
+    ssize_t videobuf_read_stream(struct videobuf_queue *q,
+				 char __user *data, size_t count,
+				 loff_t *ppos, int vbihack, int nonblocking);
+
+Either one of these functions will read frame data into data, returning the
+amount actually read; the difference is that videobuf_read_one() will only
+read a single frame, while videobuf_read_stream() will read multiple frames
+if they are needed to satisfy the count requested by the application.  A
+typical driver read() implementation will start the capture engine, call
+one of the above functions, then stop the engine before returning (though a
+smarter implementation might leave the engine running for a little while in
+anticipation of another read() call happening in the near future).
+
+The poll() function can usually be implemented with a direct call to:
+
+.. code-block:: none
+
+    unsigned int videobuf_poll_stream(struct file *file,
+				      struct videobuf_queue *q,
+				      poll_table *wait);
+
+Note that the actual wait queue eventually used will be the one associated
+with the first available buffer.
+
+When streaming I/O is done to kernel-space buffers, the driver must support
+the mmap() system call to enable user space to access the data.  In many
+V4L2 drivers, the often-complex mmap() implementation simplifies to a
+single call to:
+
+.. code-block:: none
+
+    int videobuf_mmap_mapper(struct videobuf_queue *q,
+			     struct vm_area_struct *vma);
+
+Everything else is handled by the videobuf code.
+
+The release() function requires two separate videobuf calls:
+
+.. code-block:: none
+
+    void videobuf_stop(struct videobuf_queue *q);
+    int videobuf_mmap_free(struct videobuf_queue *q);
+
+The call to videobuf_stop() terminates any I/O in progress - though it is
+still up to the driver to stop the capture engine.  The call to
+videobuf_mmap_free() will ensure that all buffers have been unmapped; if
+so, they will all be passed to the buf_release() callback.  If buffers
+remain mapped, videobuf_mmap_free() returns an error code instead.  The
+purpose is clearly to cause the closing of the file descriptor to fail if
+buffers are still mapped, but every driver in the 2.6.32 kernel cheerfully
+ignores its return value.
+
+ioctl() operations
+------------------
+
+The V4L2 API includes a very long list of driver callbacks to respond to
+the many ioctl() commands made available to user space.  A number of these
+- those associated with streaming I/O - turn almost directly into videobuf
+calls.  The relevant helper functions are:
+
+.. code-block:: none
+
+    int videobuf_reqbufs(struct videobuf_queue *q,
+			 struct v4l2_requestbuffers *req);
+    int videobuf_querybuf(struct videobuf_queue *q, struct v4l2_buffer *b);
+    int videobuf_qbuf(struct videobuf_queue *q, struct v4l2_buffer *b);
+    int videobuf_dqbuf(struct videobuf_queue *q, struct v4l2_buffer *b,
+		       int nonblocking);
+    int videobuf_streamon(struct videobuf_queue *q);
+    int videobuf_streamoff(struct videobuf_queue *q);
+
+So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's
+vidioc_reqbufs() callback which, in turn, usually only needs to locate the
+proper struct videobuf_queue pointer and pass it to videobuf_reqbufs().
+These support functions can replace a great deal of buffer management
+boilerplate in a lot of V4L2 drivers.
+
+The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
+complex, of course, since they will also need to deal with starting and
+stopping the capture engine.
+
+Buffer allocation
+-----------------
+
+Thus far, we have talked about buffers, but have not looked at how they are
+allocated.  The scatter/gather case is the most complex on this front.  For
+allocation, the driver can leave buffer allocation entirely up to the
+videobuf layer; in this case, buffers will be allocated as anonymous
+user-space pages and will be very scattered indeed.  If the application is
+using user-space buffers, no allocation is needed; the videobuf layer will
+take care of calling get_user_pages() and filling in the scatterlist array.
+
+If the driver needs to do its own memory allocation, it should be done in
+the vidioc_reqbufs() function, *after* calling videobuf_reqbufs().  The
+first step is a call to:
+
+.. code-block:: none
+
+    struct videobuf_dmabuf *videobuf_to_dma(struct videobuf_buffer *buf);
+
+The returned videobuf_dmabuf structure (defined in
+<media/videobuf-dma-sg.h>) includes a couple of relevant fields:
+
+.. code-block:: none
+
+    struct scatterlist  *sglist;
+    int                 sglen;
+
+The driver must allocate an appropriately-sized scatterlist array and
+populate it with pointers to the pieces of the allocated buffer; sglen
+should be set to the length of the array.
+
+Drivers using the vmalloc() method need not (and cannot) concern themselves
+with buffer allocation at all; videobuf will handle those details.  The
+same is normally true of contiguous-DMA drivers as well; videobuf will
+allocate the buffers (with dma_alloc_coherent()) when it sees fit.  That
+means that these drivers may be trying to do high-order allocations at any
+time, an operation which is not always guaranteed to work.  Some drivers
+play tricks by allocating DMA space at system boot time; videobuf does not
+currently play well with those drivers.
+
+As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer,
+as long as that buffer is physically contiguous.  Normal user-space
+allocations will not meet that criterion, but buffers obtained from other
+kernel drivers, or those contained within huge pages, will work with these
+drivers.
+
+Filling the buffers
+-------------------
+
+The final part of a videobuf implementation has no direct callback - it's
+the portion of the code which actually puts frame data into the buffers,
+usually in response to interrupts from the device.  For all types of
+drivers, this process works approximately as follows:
+
+ - Obtain the next available buffer and make sure that somebody is actually
+   waiting for it.
+
+ - Get a pointer to the memory and put video data there.
+
+ - Mark the buffer as done and wake up the process waiting for it.
+
+Step (1) above is done by looking at the driver-managed list_head structure
+- the one which is filled in the buf_queue() callback.  Because starting
+the engine and enqueueing buffers are done in separate steps, it's possible
+for the engine to be running without any buffers available - in the
+vmalloc() case especially.  So the driver should be prepared for the list
+to be empty.  It is equally possible that nobody is yet interested in the
+buffer; the driver should not remove it from the list or fill it until a
+process is waiting on it.  That test can be done by examining the buffer's
+done field (a wait_queue_head_t structure) with waitqueue_active().
+
+A buffer's state should be set to VIDEOBUF_ACTIVE before being mapped for
+DMA; that ensures that the videobuf layer will not try to do anything with
+it while the device is transferring data.
+
+For scatter/gather drivers, the needed memory pointers will be found in the
+scatterlist structure described above.  Drivers using the vmalloc() method
+can get a memory pointer with:
+
+.. code-block:: none
+
+    void *videobuf_to_vmalloc(struct videobuf_buffer *buf);
+
+For contiguous DMA drivers, the function to use is:
+
+.. code-block:: none
+
+    dma_addr_t videobuf_to_dma_contig(struct videobuf_buffer *buf);
+
+The contiguous DMA API goes out of its way to hide the kernel-space address
+of the DMA buffer from drivers.
+
+The final step is to set the size field of the relevant videobuf_buffer
+structure to the actual size of the captured image, set state to
+VIDEOBUF_DONE, then call wake_up() on the done queue.  At this point, the
+buffer is owned by the videobuf layer and the driver should not touch it
+again.
+
+Developers who are interested in more information can go into the relevant
+header files; there are a few low-level functions declared there which have
+not been talked about here.  Note also that all of these calls are exported
+GPL-only, so they will not be available to non-GPL kernel modules.

-HOWTO: Get An Avermedia DVB-T working under Linux
--------------------------------------------------
-
-February 14th 2006
-
-.. note::
-
-   This documentation is outdated. Please check at the DVB wiki
-   at https://linuxtv.org/wiki for more updated info.
-
-   There's a section there specific for Avermedia boards at:
-   https://linuxtv.org/wiki/index.php/AVerMedia
-
-
-Assumptions and Introduction
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It  is assumed that the reader understands the basic structure
-of  the Linux Kernel DVB drivers and the general principles of
-Digital TV.
-
-One  significant difference between Digital TV and Analogue TV
-that  the  unwary  (like  myself)  should  consider  is  that,
-although  the  component  structure  of budget DVB-T cards are
-substantially  similar  to Analogue TV cards, they function in
-substantially different ways.
-
-The  purpose  of  an  Analogue TV is to receive and display an
-Analogue  Television  signal. An Analogue TV signal (otherwise
-known  as  composite  video)  is  an  analogue  encoding  of a
-sequence  of  image frames (25 per second) rasterised using an
-interlacing   technique.   Interlacing  takes  two  fields  to
-represent  one  frame.  Computers today are at their best when
-dealing  with  digital  signals,  not  analogue  signals and a
-composite  video signal is about as far removed from a digital
-data stream as you can get. Therefore, an Analogue TV card for
-a PC has the following purpose:
-
-* Tune the receiver to receive a broadcast signal
-* demodulate the broadcast signal
-* demultiplex  the  analogue video signal and analogue audio
-  signal. **NOTE:** some countries employ a digital audio signal
-  embedded  within the modulated composite analogue signal -
-  NICAM.)
-* digitize  the analogue video signal and make the resulting
-  datastream available to the data bus.
-
-The  digital  datastream from an Analogue TV card is generated
-by  circuitry on the card and is often presented uncompressed.
-For  a PAL TV signal encoded at a resolution of 768x576 24-bit
-color pixels over 25 frames per second - a fair amount of data
-is  generated and must be processed by the PC before it can be
-displayed  on the video monitor screen. Some Analogue TV cards
-for  PCs  have  onboard  MPEG2  encoders  which permit the raw
-digital  data  stream  to be presented to the PC in an encoded
-and  compressed  form  -  similar  to the form that is used in
-Digital TV.
-
-The  purpose of a simple budget digital TV card (DVB-T,C or S)
-is to simply:
-
-* Tune the received to receive a broadcast signal.
-* Extract  the encoded digital datastream from the broadcast
-  signal.
-* Make  the  encoded digital datastream (MPEG2) available to
-  the data bus.
-
-The  significant  difference between the two is that the tuner
-on  the analogue TV card spits out an Analogue signal, whereas
-the  tuner  on  the  digital  TV  card  spits out a compressed
-encoded   digital   datastream.   As  the  signal  is  already
-digitised,  it  is  trivial  to pass this datastream to the PC
-databus  with  minimal  additional processing and then extract
-the  digital  video  and audio datastreams passing them to the
-appropriate software or hardware for decoding and viewing.
-
-The Avermedia DVB-T
-~~~~~~~~~~~~~~~~~~~
-
-The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
-
-* RF Tuner Input
-* Composite Video Input (RCA Jack)
-* SVIDEO Input (Mini-DIN)
-
-The  RF  Tuner  Input  is the input to the tuner module of the
-card.  The  Tuner  is  otherwise known as the "Frontend" . The
-Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
-post  to  the  linux-dvb  mailing  list  ascertained  that the
-Microtune  7202D  is  supported  by the sp887x driver which is
-found in the dvb-hw CVS module.
-
-The  DVB-T card is based around the BT878 chip which is a very
-common multimedia bridge and often found on Analogue TV cards.
-There is no on-board MPEG2 decoder, which means that all MPEG2
-decoding  must  be done in software, or if you have one, on an
-MPEG2 hardware decoding card or chipset.
-
-
-Getting the card going
-~~~~~~~~~~~~~~~~~~~~~~
-
-In order to fire up the card, it is necessary to load a number
-of modules from the DVB driver set. Prior to this it will have
-been  necessary to download these drivers from the linuxtv CVS
-server and compile them successfully.
-
-Depending on the card's feature set, the Device Driver API for
-DVB under Linux will expose some of the following device files
-in the /dev tree:
-
-* /dev/dvb/adapter0/audio0
-* /dev/dvb/adapter0/ca0
-* /dev/dvb/adapter0/demux0
-* /dev/dvb/adapter0/dvr0
-* /dev/dvb/adapter0/frontend0
-* /dev/dvb/adapter0/net0
-* /dev/dvb/adapter0/osd0
-* /dev/dvb/adapter0/video0
-
-The  primary  device  nodes that we are interested in (at this
-stage) for the Avermedia DVB-T are:
-
-* /dev/dvb/adapter0/dvr0
-* /dev/dvb/adapter0/frontend0
-
-The dvr0 device node is used to read the MPEG2 Data Stream and
-the frontend0 node is used to tune the frontend tuner module.
-
-At  this  stage,  it  has  not  been  able  to  ascertain  the
-functionality  of the remaining device nodes in respect of the
-Avermedia  DVBT.  However,  full  functionality  in respect of
-tuning,  receiving  and  supplying  the  MPEG2  data stream is
-possible  with the currently available versions of the driver.
-It  may be possible that additional functionality is available
-from  the  card  (i.e.  viewing the additional analogue inputs
-that  the card presents), but this has not been tested yet. If
-I get around to this, I'll update the document with whatever I
-find.
-
-To  power  up  the  card,  load  the  following modules in the
-following order:
-
-* modprobe bttv (normally loaded automatically)
-* modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
-
-Insertion  of  these  modules  into  the  running  kernel will
-activate the appropriate DVB device nodes. It is then possible
-to start accessing the card with utilities such as scan, tzap,
-dvbstream etc.
-
-The frontend module sp887x.o, requires an external   firmware.
-Please use  the  command "get_dvb_firmware sp887x" to download
-it. Then copy it to /usr/lib/hotplug/firmware or /lib/firmware/
-(depending on configuration of firmware hotplug).
-
-Receiving DVB-T in Australia
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-I  have  no  experience of DVB-T in other countries other than
-Australia,  so  I will attempt to explain how it works here in
-Melbourne  and how this affects the configuration of the DVB-T
-card.
-
-The  Digital  Broadcasting  Australia  website has a Reception
-locatortool which provides information on transponder channels
-and  frequencies.  My  local  transmitter  happens to be Mount
-Dandenong.
-
-The frequencies broadcast by Mount Dandenong are:
-
-Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
-Broadcaster Channel Frequency
-ABC         VHF 12  226.5 MHz
-TEN         VHF 11  219.5 MHz
-NINE        VHF 8   191.625 MHz
-SEVEN       VHF 6   177.5 MHz
-SBS         UHF 29  536.5 MHz
-
-The Scan utility has a set of compiled-in defaults for various
-countries and regions, but if they do not suit, or if you have
-a pre-compiled scan binary, you can specify a data file on the
-command  line which contains the transponder frequencies. Here
-is a sample file for the above channel transponders:
-
-::
-
-	# Data file for DVB scan program
-	#
-	# C Frequency SymbolRate FEC QAM
-	# S Frequency Polarisation SymbolRate FEC
-	# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
-	T 226500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-	T 191625000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-	T 219500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-	T 177500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-	T 536500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-
-The   defaults   for   the  transponder  frequency  and  other
-modulation parameters were obtained from www.dba.org.au.
-
-When  Scan  runs, it will output channels.conf information for
-any  channel's transponders which the card's frontend can lock
-onto.  (i.e.  any  whose  signal  is  strong  enough  at  your
-antenna).
-
-Here's my channels.conf file for anyone who's interested:

-Known Limitations
-~~~~~~~~~~~~~~~~~
-
-At  present  I can say with confidence that the frontend tunes
-via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
-via   /dev/dvb/adapter{x}/dvr0.   I   have   not   tested  the
-functionality  of any other part of the card yet. I will do so
-over time and update this document.
-
-There  are some limitations in the i2c layer due to a returned
-error message inconsistency. Although this generates errors in
-dmesg  and  the  system logs, it does not appear to affect the
-ability of the frontend to function correctly.
-
-Further Update
-~~~~~~~~~~~~~~
-
-dvbstream  and  VideoLAN  Client on windows works a treat with
-DVB,  in  fact  this  is  currently  serving as my main way of
-viewing  DVB-T  at  the  moment.  Additionally, VLC is happily
-decoding  HDTV  signals,  although  the PC is dropping the odd
-frame here and there - I assume due to processing capability -
-as all the decoding is being done under windows in software.
-
-Many  thanks to Nigel Pearson for the updates to this document
-since the recent revision of the driver.

-How to get the bt8xx cards working
-==================================

-
-General information
--------------------
-
-This class of cards has a bt878a as the PCI interface, and require the bttv driver
-for accessing the i2c bus and the gpio pins of the bt8xx chipset.
-Please see Documentation/media/dvb-drivers/cards.rst => o Cards based on the Conexant Bt8xx PCI bridge:
-
-Compiling kernel please enable:
-
-#) ``Device drivers`` => ``Multimedia devices`` => ``Video For Linux`` => ``Enable Video for Linux API 1 (DEPRECATED)``
-#) ``Device drivers`` => ``Multimedia devices`` => ``Video For Linux`` => ``Video Capture Adapters`` => ``BT848 Video For Linux``
-#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Bt8xx based PCI Cards``
-
-  Please use the following options with care as deselection of drivers which are in fact necessary may result in DVB devices that cannot be tuned due to lack of driver support:
-  You can save RAM by deselecting every frontend module that your DVB card does not need.
-
-  First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
-
-#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Load and attach frontend modules as needed``
-
-  If you know the frontend driver that your card needs please enable:
-
-#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Customise DVB Frontends`` => ``Customise the frontend modules to build``
-
- Then please select your card-specific frontend module.
-
-Loading Modules
----------------
-
-Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
-Exceptions are:
-- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
-People running udev please see Documentation/media/dvb-drivers/udev.rst.
-
-In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
-
-Running TwinHan and Clones
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: none
-
-	$ modprobe bttv card=113
-	$ modprobe dst
-
-Useful parameters for verbosity level and debugging the dst module:
-
-.. code-block:: none
-
-	verbose=0:		messages are disabled
-		1:		only error messages are displayed
-		2:		notifications are displayed
-		3:		other useful messages are displayed
-		4:		debug setting
-	dst_addons=0:		card is a free to air (FTA) card only
-		0x20:	card has a conditional access slot for scrambled channels
-
-The autodetected values are determined by the cards' "response string".
-In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
-For bug reports please send in a complete log with verbose=4 activated.
-Please also see Documentation/media/dvb-drivers/ci.rst.

-Hardware supported by the linuxtv.org DVB drivers
-=================================================
-
-.. note::
-
-   This documentation is outdated. Please check at the DVB wiki
-   at https://linuxtv.org/wiki for more updated info.
-
-   Please look at
-   https://linuxtv.org/wiki/index.php/Hardware_Device_Information
-   for an updated list of supported cards.
-
-Generally, the DVB hardware manufacturers frequently change the
-frontends (i.e. tuner / demodulator units) used, usually without
-changing the product name, revision number or specs. Some cards
-are also available in versions with different frontends for
-DVB-S/DVB-C/DVB-T. Thus the frontend drivers are listed separately.
-
-.. note::
-
-  #) There is no guarantee that every frontend driver works
-     out of the box with every card, because of different wiring.
-
-  #) The demodulator chips can be used with a variety of
-     tuner/PLL chips, and not all combinations are supported. Often
-     the demodulator and tuner/PLL chip are inside a metal box for
-     shielding, and the whole metal box has its own part number.

-Digital TV Conditional Access Interface (CI API)
-================================================
-
-
-.. note::
-
-   This documentation is outdated.
-
-This document describes the usage of the high level CI API as
-in accordance to the Linux DVB API. This is a not a documentation for the,
-existing low level CI API.
-
-.. note::
-
-   For the Twinhan/Twinhan clones, the dst_ca module handles the CI
-   hardware handling.This module is loaded automatically if a CI
-   (Common Interface, that holds the CAM (Conditional Access Module)
-   is detected.
-
-ca_zap
-~~~~~~
-
-A userspace application, like ``ca_zap`` is required to handle encrypted
-MPEG-TS streams.
-
-The ``ca_zap`` userland application is in charge of sending the
-descrambling related information to the Conditional Access Module (CAM).
-
-This application requires the following to function properly as of now.
-
-a) Tune to a valid channel, with szap.
-
-  eg: $ szap -c channels.conf -r "TMC" -x
-
-b) a channels.conf containing a valid PMT PID
-
-  eg: TMC:11996:h:0:27500:278:512:650:321
-
-  here 278 is a valid PMT PID. the rest of the values are the
-  same ones that szap uses.
-
-c) after running a szap, you have to run ca_zap, for the
-   descrambler to function,
-
-  eg: $ ca_zap channels.conf "TMC"
-
-d) Hopefully enjoy your favourite subscribed channel as you do with
-   a FTA card.
-
-.. note::
-
-  Currently ca_zap, and dst_test, both are meant for demonstration
-  purposes only, they can become full fledged applications if necessary.
-
-
-Cards that fall in this category
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-At present the cards that fall in this category are the Twinhan and its
-clones, these cards are available as VVMER, Tomato, Hercules, Orange and
-so on.
-
-CI modules that are supported
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The CI module support is largely dependent upon the firmware on the cards
-Some cards do support almost all of the available CI modules. There is
-nothing much that can be done in order to make additional CI modules
-working with these cards.
-
-Modules that have been tested by this driver at present are
-
-(1) Irdeto 1 and 2 from SCM
-(2) Viaccess from SCM
-(3) Dragoncam
-
-The High level CI API
-~~~~~~~~~~~~~~~~~~~~~
-
-For the programmer
-^^^^^^^^^^^^^^^^^^
-
-With the High Level CI approach any new card with almost any random
-architecture can be implemented with this style, the definitions
-inside the switch statement can be easily adapted for any card, thereby
-eliminating the need for any additional ioctls.
-
-The disadvantage is that the driver/hardware has to manage the rest. For
-the application programmer it would be as simple as sending/receiving an
-array to/from the CI ioctls as defined in the Linux DVB API. No changes
-have been made in the API to accommodate this feature.
-
-
-Why the need for another CI interface?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This is one of the most commonly asked question. Well a nice question.
-Strictly speaking this is not a new interface.
-
-The CI interface is defined in the DVB API in ca.h as:
-
-.. code-block:: c
-
-	typedef struct ca_slot_info {
-		int num;               /* slot number */
-
-		int type;              /* CA interface this slot supports */
-	#define CA_CI            1     /* CI high level interface */
-	#define CA_CI_LINK       2     /* CI link layer level interface */
-	#define CA_CI_PHYS       4     /* CI physical layer level interface */
-	#define CA_DESCR         8     /* built-in descrambler */
-	#define CA_SC          128     /* simple smart card interface */
-
-		unsigned int flags;
-	#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
-	#define CA_CI_MODULE_READY   2
-	} ca_slot_info_t;
-
-This CI interface follows the CI high level interface, which is not
-implemented by most applications. Hence this area is revisited.
-
-This CI interface is quite different in the case that it tries to
-accommodate all other CI based devices, that fall into the other categories.
-
-This means that this CI interface handles the EN50221 style tags in the
-Application layer only and no session management is taken care of by the
-application. The driver/hardware will take care of all that.
-
-This interface is purely an EN50221 interface exchanging APDU's. This
-means that no session management, link layer or a transport layer do
-exist in this case in the application to driver communication. It is
-as simple as that. The driver/hardware has to take care of that.
-
-With this High Level CI interface, the interface can be defined with the
-regular ioctls.
-
-All these ioctls are also valid for the High level CI interface
-
-#define CA_RESET          _IO('o', 128)
-#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
-#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)
-#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
-#define CA_GET_MSG        _IOR('o', 132, ca_msg_t)
-#define CA_SEND_MSG       _IOW('o', 133, ca_msg_t)
-#define CA_SET_DESCR      _IOW('o', 134, ca_descr_t)
-
-
-On querying the device, the device yields information thus:
-
-.. code-block:: none
-
-	CA_GET_SLOT_INFO
-	----------------------------
-	Command = [info]
-	APP: Number=[1]
-	APP: Type=[1]
-	APP: flags=[1]
-	APP: CI High level interface
-	APP: CA/CI Module Present

-	Command = [caps]
-	APP: Slots=[1]
-	APP: Type=[1]
-	APP: Descrambler keys=[16]
-	APP: Type=[1]
-
-	CA_SEND_MSG
-	----------------------------
-	Descriptors(Program Level)=[ 09 06 06 04 05 50 ff f1]
-	Found CA descriptor @ program level
-
-	(20) ES type=[2] ES pid=[201]  ES length =[0 (0x0)]
-	(25) ES type=[4] ES pid=[301]  ES length =[0 (0x0)]
-	ca_message length is 25 (0x19) bytes
-	EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
-
-
-Not all ioctl's are implemented in the driver from the API, the other
-features of the hardware that cannot be implemented by the API are achieved
-using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
-used to exchange the data to maintain compatibility with other hardware.
-
-.. code-block:: c
-
-	/* a message to/from a CI-CAM */
-	typedef struct ca_msg {
-		unsigned int index;
-		unsigned int type;
-		unsigned int length;
-		unsigned char msg[256];
-	} ca_msg_t;
-
-
-The flow of data can be described thus,
-
-.. code-block:: none
-
-	App (User)

-
-
-The High Level CI interface uses the EN50221 DVB standard, following a
-standard ensures futureproofness.

-FAQ
-===
-
-.. note::
-
-   This documentation is outdated. Please check at the DVB wiki
-   at https://linuxtv.org/wiki for more updated info.
-
-Some very frequently asked questions about linuxtv-dvb
-
-1. The signal seems to die a few seconds after tuning.
-
-	It's not a bug, it's a feature. Because the frontends have
-	significant power requirements (and hence get very hot), they
-	are powered down if they are unused (i.e. if the frontend device
-	is closed). The dvb-core.o module parameter "dvb_shutdown_timeout"
-	allow you to change the timeout (default 5 seconds). Setting the
-	timeout to 0 disables the timeout feature.
-
-2. How can I watch TV?
-
-	The driver distribution includes some simple utilities which
-	are mainly intended for testing and to demonstrate how the
-	DVB API works.
-
-	Depending on whether you have a DVB-S, DVB-C or DVB-T card, use
-	apps/szap/szap, czap or tzap. You must supply a channel list
-	in ~/.[sct]zap/channels.conf. If you are lucky you can just copy
-	one of the supplied channel lists, or you can create a new one
-	by running apps/scan/scan. If you run scan on an unknown network
-	you might have to supply some start data in apps/scan/initial.h.
-
-	If you have a card with a built-in hardware MPEG-decoder the
-	drivers create a video4linux device (/dev/v4l/video0) which
-	you can use to watch TV with any v4l application. xawtv is known
-	to work. Note that you cannot change channels with xawtv, you
-	have to zap using [sct]zap. If you want a nice application for
-	TV watching and record/playback, have a look at VDR.
-
-	If your card does not have a hardware MPEG decoder you need
-	a software MPEG decoder. Mplayer or xine are known to work.
-	Newsflash: MythTV also has DVB support now.
-	Note: Only very recent versions of Mplayer and xine can decode.
-	MPEG2 transport streams (TS) directly. Then, run
-	'[sct]zap channelname -r' in one xterm, and keep it running,
-	and start 'mplayer - < /dev/dvb/adapter0/dvr0' or
-	'xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0' in a second xterm.
-	That's all far from perfect, but it seems no one has written
-	a nice DVB application which includes a builtin software MPEG
-	decoder yet.
-
-	Newsflash: Newest xine directly supports DVB. Just copy your
-	channels.conf to ~/.xine and start 'xine dvb://', or select
-	the DVB button in the xine GUI. Channel switching works using the
-	numpad pgup/pgdown (NP9 / NP3) keys to scroll through the channel osd
-	menu and pressing numpad-enter to switch to the selected channel.
-
-	Note: Older versions of xine and mplayer understand MPEG program
-	streams (PS) only, and can be used in conjunction with the
-	ts2ps tool from the Metzler Brother's dvb-mpegtools package.
-

-		or view dvb/mpeg/dsm-cc/mhp stream information (TS,
-		PES, SECTION)
-
-4. Can't get a signal tuned correctly
-
-	If you are using a Technotrend/Hauppauge DVB-C card *without* analog
-	module, you might have to use module parameter adac=-1 (dvb-ttpci.o).
-
-5. The dvb_net device doesn't give me any packets at all
-
-	Run tcpdump on the dvb0_0 interface. This sets the interface
-	into promiscuous mode so it accepts any packets from the PID
-	you have configured with the dvbnet utility. Check if there
-	are any packets with the IP addr and MAC addr you have
-	configured with ifconfig.
-
-	If tcpdump doesn't give you any output, check the statistics
-	which ifconfig outputs. (Note: If the MAC address is wrong,
-	dvb_net won't get any input; thus you have to run tcpdump
-	before checking the statistics.) If there are no packets at
-	all then maybe the PID is wrong. If there are error packets,
-	then either the PID is wrong or the stream does not conform to
-	the MPE standard (EN 301 192, http://www.etsi.org/). You can
-	use e.g. dvbsnoop for debugging.
-
-6. The dvb_net device doesn't give me any multicast packets
-
-	Check your routes if they include the multicast address range.
-	Additionally make sure that "source validation by reversed path
-	lookup" is disabled:
-
-.. code-block:: none
-
-	  $ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"
-
-7. What the hell are all those modules that need to be loaded?
-
-	For a dvb-ttpci av7110 based full-featured card the following
-	modules are loaded:
-
-	- videodev: Video4Linux core module. This is the base module that
-	  gives you access to the "analog" tv picture of the av7110 mpeg2
-	  decoder.
-
-	- v4l2-common: common functions for Video4Linux-2 drivers
-
-	- v4l1-compat: backward compatibility layer for Video4Linux-1 legacy
-	  applications
-
-	- dvb-core: DVB core module. This provides you with the
-	  /dev/dvb/adapter entries
-
-	- saa7146: SAA7146 core driver. This is need to access any SAA7146
-	  based card in your system.
-
-	- saa7146_vv: SAA7146 video and vbi functions. These are only needed
-	  for full-featured cards.
-
-	- videobuf-dma-sg: capture helper module for the saa7146_vv driver. This
-	  one is responsible to handle capture buffers.
-
-	- dvb-ttpci: The main driver for AV7110 based, full-featured
-	  DVB-S/C/T cards

-UDEV rules for DVB
-==================
-
-.. note::
-
-   #) This documentation is outdated. Udev on modern distributions auto-detect
-      the DVB devices.
-
-   #) **TODO:** change this document to explain how to make DVB devices
-      persistent, as, when a machine has multiple devices, they may be detected
-      on different orders, which could cause apps that relies on the device
-      numbers to fail.
-
-The DVB subsystem currently registers to the sysfs subsystem using the
-"class_simple" interface.
-
-This means that only the basic information like module loading parameters
-are presented through sysfs. Other things that might be interesting are
-currently **not** available.
-
-Nevertheless it's now possible to add proper udev rules so that the
-DVB device nodes are created automatically.
-
-We assume that you have udev already up and running and that have been
-creating the DVB device nodes manually up to now due to the missing sysfs
-support.
-
-0. Don't forget to disable your current method of creating the
-device nodes manually.
-
-1. Unfortunately, you'll need a helper script to transform the kernel
-sysfs device name into the well known dvb adapter / device naming scheme.
-The script should be called "dvb.sh" and should be placed into a script
-dir where udev can execute it, most likely /etc/udev/scripts/
-
-So, create a new file /etc/udev/scripts/dvb.sh and add the following:
-
-.. code-block:: none
-
-	#!/bin/sh
-	/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'
-
-Don't forget to make the script executable with "chmod".
-
-1. You need to create a proper udev rule that will create the device nodes
-like you know them. All real distributions out there scan the /etc/udev/rules.d
-directory for rule files. The main udev configuration file /etc/udev/udev.conf
-will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
-
-Create a new rule file in that directory called "dvb.rule" and add the following line:
-
-.. code-block:: none
-
-	KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
-
-If you want more control over the device nodes (for example a special group membership)
-have a look at "man udev".
-
-For every device that registers to the sysfs subsystem with a "dvb" prefix,
-the helper script /etc/udev/scripts/dvb.sh is invoked, which will then
-create the proper device node in your /dev/ directory.

-MIPI CSI-2
-==========
-
-CSI-2 is a data bus intended for transferring images from cameras to
-the host SoC. It is defined by the `MIPI alliance`_.
-
-.. _`MIPI alliance`: http://www.mipi.org/
-
-Transmitter drivers
--------------------
-
-CSI-2 transmitter, such as a sensor or a TV tuner, drivers need to
-provide the CSI-2 receiver with information on the CSI-2 bus
-configuration. These include the V4L2_CID_LINK_FREQ and
-V4L2_CID_PIXEL_RATE controls and
-(:c:type:`v4l2_subdev_video_ops`->s_stream() callback). These
-interface elements must be present on the sub-device represents the
-CSI-2 transmitter.
-
-The V4L2_CID_LINK_FREQ control is used to tell the receiver driver the
-frequency (and not the symbol rate) of the link. The
-V4L2_CID_PIXEL_RATE is may be used by the receiver to obtain the pixel
-rate the transmitter uses. The
-:c:type:`v4l2_subdev_video_ops`->s_stream() callback provides an
-ability to start and stop the stream.
-
-The value of the V4L2_CID_PIXEL_RATE is calculated as follows::
-
-	pixel_rate = link_freq * 2 * nr_of_lanes / bits_per_sample
-
-where
-
-.. list-table:: variables in pixel rate calculation
-   :header-rows: 1
-
-   * - variable or constant
-     - description
-   * - link_freq
-     - The value of the V4L2_CID_LINK_FREQ integer64 menu item.
-   * - nr_of_lanes
-     - Number of data lanes used on the CSI-2 link. This can
-       be obtained from the OF endpoint configuration.
-   * - 2
-     - Two bits are transferred per clock cycle per lane.
-   * - bits_per_sample
-     - Number of bits per sample.
-
-The transmitter drivers must, if possible, configure the CSI-2
-transmitter to *LP-11 mode* whenever the transmitter is powered on but
-not active, and maintain *LP-11 mode* until stream on. Only at stream
-on should the transmitter activate the clock on the clock lane and
-transition to *HS mode*.
-
-Some transmitters do this automatically but some have to be explicitly
-programmed to do so, and some are unable to do so altogether due to
-hardware constraints.
-
-Stopping the transmitter
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-A transmitter stops sending the stream of images as a result of
-calling the ``.s_stream()`` callback. Some transmitters may stop the
-stream at a frame boundary whereas others stop immediately,
-effectively leaving the current frame unfinished. The receiver driver
-should not make assumptions either way, but function properly in both
-cases.
-
-Receiver drivers
-----------------
-
-Before the receiver driver may enable the CSI-2 transmitter by using
-the :c:type:`v4l2_subdev_video_ops`->s_stream(), it must have powered
-the transmitter up by using the
-:c:type:`v4l2_subdev_core_ops`->s_power() callback. This may take
-place either indirectly by using :c:func:`v4l2_pipeline_pm_get` or
-directly.
-
-Formats
--------
-
-The media bus pixel codes document parallel formats. Should the pixel data be
-transported over a serial bus, the media bus pixel code that describes a
-parallel format that transfers a sample on a single clock cycle is used.

-V4L2 sub-devices
-----------------
-
-Many drivers need to communicate with sub-devices. These devices can do all
-sort of tasks, but most commonly they handle audio and/or video muxing,
-encoding or decoding. For webcams common sub-devices are sensors and camera
-controllers.
-
-Usually these are I2C devices, but not necessarily. In order to provide the
-driver with a consistent interface to these sub-devices the
-:c:type:`v4l2_subdev` struct (v4l2-subdev.h) was created.
-
-Each sub-device driver must have a :c:type:`v4l2_subdev` struct. This struct
-can be stand-alone for simple sub-devices or it might be embedded in a larger
-struct if more state information needs to be stored. Usually there is a
-low-level device struct (e.g. ``i2c_client``) that contains the device data as
-setup by the kernel. It is recommended to store that pointer in the private
-data of :c:type:`v4l2_subdev` using :c:func:`v4l2_set_subdevdata`. That makes
-it easy to go from a :c:type:`v4l2_subdev` to the actual low-level bus-specific
-device data.
-
-You also need a way to go from the low-level struct to :c:type:`v4l2_subdev`.
-For the common i2c_client struct the i2c_set_clientdata() call is used to store
-a :c:type:`v4l2_subdev` pointer, for other buses you may have to use other
-methods.
-
-Bridges might also need to store per-subdev private data, such as a pointer to
-bridge-specific per-subdev private data. The :c:type:`v4l2_subdev` structure
-provides host private data for that purpose that can be accessed with
-:c:func:`v4l2_get_subdev_hostdata` and :c:func:`v4l2_set_subdev_hostdata`.
-
-From the bridge driver perspective, you load the sub-device module and somehow
-obtain the :c:type:`v4l2_subdev` pointer. For i2c devices this is easy: you call
-``i2c_get_clientdata()``. For other buses something similar needs to be done.
-Helper functions exists for sub-devices on an I2C bus that do most of this
-tricky work for you.
-
-Each :c:type:`v4l2_subdev` contains function pointers that sub-device drivers
-can implement (or leave ``NULL`` if it is not applicable). Since sub-devices can
-do so many different things and you do not want to end up with a huge ops struct
-of which only a handful of ops are commonly implemented, the function pointers
-are sorted according to category and each category has its own ops struct.
-
-The top-level ops struct contains pointers to the category ops structs, which
-may be NULL if the subdev driver does not support anything from that category.
-
-It looks like this:
-
-.. code-block:: c
-
-	struct v4l2_subdev_core_ops {
-		int (*log_status)(struct v4l2_subdev *sd);
-		int (*init)(struct v4l2_subdev *sd, u32 val);
-		...
-	};
-
-	struct v4l2_subdev_tuner_ops {
-		...
-	};
-
-	struct v4l2_subdev_audio_ops {
-		...
-	};
-
-	struct v4l2_subdev_video_ops {
-		...
-	};
-
-	struct v4l2_subdev_pad_ops {
-		...
-	};
-
-	struct v4l2_subdev_ops {
-		const struct v4l2_subdev_core_ops  *core;
-		const struct v4l2_subdev_tuner_ops *tuner;
-		const struct v4l2_subdev_audio_ops *audio;
-		const struct v4l2_subdev_video_ops *video;
-		const struct v4l2_subdev_pad_ops *video;
-	};
-
-The core ops are common to all subdevs, the other categories are implemented
-depending on the sub-device. E.g. a video device is unlikely to support the
-audio ops and vice versa.
-
-This setup limits the number of function pointers while still making it easy
-to add new ops and categories.
-
-A sub-device driver initializes the :c:type:`v4l2_subdev` struct using:
-
-	:c:func:`v4l2_subdev_init <v4l2_subdev_init>`
-	(:c:type:`sd <v4l2_subdev>`, &\ :c:type:`ops <v4l2_subdev_ops>`).
-
-
-Afterwards you need to initialize :c:type:`sd <v4l2_subdev>`->name with a
-unique name and set the module owner. This is done for you if you use the
-i2c helper functions.
-
-If integration with the media framework is needed, you must initialize the
-:c:type:`media_entity` struct embedded in the :c:type:`v4l2_subdev` struct
-(entity field) by calling :c:func:`media_entity_pads_init`, if the entity has
-pads:
-
-.. code-block:: c
-
-	struct media_pad *pads = &my_sd->pads;
-	int err;
-
-	err = media_entity_pads_init(&sd->entity, npads, pads);
-
-The pads array must have been previously initialized. There is no need to
-manually set the struct :c:type:`media_entity` function and name fields, but the
-revision field must be initialized if needed.
-
-A reference to the entity will be automatically acquired/released when the
-subdev device node (if any) is opened/closed.
-
-Don't forget to cleanup the media entity before the sub-device is destroyed:
-
-.. code-block:: c
-
-	media_entity_cleanup(&sd->entity);
-
-If the subdev driver intends to process video and integrate with the media
-framework, it must implement format related functionality using
-:c:type:`v4l2_subdev_pad_ops` instead of :c:type:`v4l2_subdev_video_ops`.
-
-In that case, the subdev driver may set the link_validate field to provide
-its own link validation function. The link validation function is called for
-every link in the pipeline where both of the ends of the links are V4L2
-sub-devices. The driver is still responsible for validating the correctness
-of the format configuration between sub-devices and video nodes.
-
-If link_validate op is not set, the default function
-:c:func:`v4l2_subdev_link_validate_default` is used instead. This function
-ensures that width, height and the media bus pixel code are equal on both source
-and sink of the link. Subdev drivers are also free to use this function to
-perform the checks mentioned above in addition to their own checks.
-
-There are currently two ways to register subdevices with the V4L2 core. The
-first (traditional) possibility is to have subdevices registered by bridge
-drivers. This can be done when the bridge driver has the complete information
-about subdevices connected to it and knows exactly when to register them. This
-is typically the case for internal subdevices, like video data processing units
-within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected
-to SoCs, which pass information about them to bridge drivers, usually in their
-platform data.
-
-There are however also situations where subdevices have to be registered
-asynchronously to bridge devices. An example of such a configuration is a Device
-Tree based system where information about subdevices is made available to the
-system independently from the bridge devices, e.g. when subdevices are defined
-in DT as I2C device nodes. The API used in this second case is described further
-below.
-
-Using one or the other registration method only affects the probing process, the
-run-time bridge-subdevice interaction is in both cases the same.
-
-In the synchronous case a device (bridge) driver needs to register the
-:c:type:`v4l2_subdev` with the v4l2_device:
-
-	:c:func:`v4l2_device_register_subdev <v4l2_device_register_subdev>`
-	(:c:type:`v4l2_dev <v4l2_device>`, :c:type:`sd <v4l2_subdev>`).
-
-This can fail if the subdev module disappeared before it could be registered.
-After this function was called successfully the subdev->dev field points to
-the :c:type:`v4l2_device`.
-
-If the v4l2_device parent device has a non-NULL mdev field, the sub-device
-entity will be automatically registered with the media device.
-
-You can unregister a sub-device using:
-
-	:c:func:`v4l2_device_unregister_subdev <v4l2_device_unregister_subdev>`
-	(:c:type:`sd <v4l2_subdev>`).
-
-
-Afterwards the subdev module can be unloaded and
-:c:type:`sd <v4l2_subdev>`->dev == ``NULL``.
-
-You can call an ops function either directly:
-
-.. code-block:: c
-
-	err = sd->ops->core->g_std(sd, &norm);
-
-but it is better and easier to use this macro:
-
-.. code-block:: c
-
-	err = v4l2_subdev_call(sd, core, g_std, &norm);
-
-The macro will to the right ``NULL`` pointer checks and returns ``-ENODEV``
-if :c:type:`sd <v4l2_subdev>` is ``NULL``, ``-ENOIOCTLCMD`` if either
-:c:type:`sd <v4l2_subdev>`->core or :c:type:`sd <v4l2_subdev>`->core->g_std is ``NULL``, or the actual result of the
-:c:type:`sd <v4l2_subdev>`->ops->core->g_std ops.
-
-It is also possible to call all or a subset of the sub-devices:
-
-.. code-block:: c
-
-	v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
-
-Any subdev that does not support this ops is skipped and error results are
-ignored. If you want to check for errors use this:
-
-.. code-block:: c
-
-	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
-
-Any error except ``-ENOIOCTLCMD`` will exit the loop with that error. If no
-errors (except ``-ENOIOCTLCMD``) occurred, then 0 is returned.
-
-The second argument to both calls is a group ID. If 0, then all subdevs are
-called. If non-zero, then only those whose group ID match that value will
-be called. Before a bridge driver registers a subdev it can set
-:c:type:`sd <v4l2_subdev>`->grp_id to whatever value it wants (it's 0 by
-default). This value is owned by the bridge driver and the sub-device driver
-will never modify or use it.
-
-The group ID gives the bridge driver more control how callbacks are called.
-For example, there may be multiple audio chips on a board, each capable of
-changing the volume. But usually only one will actually be used when the
-user want to change the volume. You can set the group ID for that subdev to
-e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
-``v4l2_device_call_all()``. That ensures that it will only go to the subdev
-that needs it.
-
-If the sub-device needs to notify its v4l2_device parent of an event, then
-it can call ``v4l2_subdev_notify(sd, notification, arg)``. This macro checks
-whether there is a ``notify()`` callback defined and returns ``-ENODEV`` if not.
-Otherwise the result of the ``notify()`` call is returned.
-
-The advantage of using :c:type:`v4l2_subdev` is that it is a generic struct and
-does not contain any knowledge about the underlying hardware. So a driver might
-contain several subdevs that use an I2C bus, but also a subdev that is
-controlled through GPIO pins. This distinction is only relevant when setting
-up the device, but once the subdev is registered it is completely transparent.
-
-In the asynchronous case subdevice probing can be invoked independently of the
-bridge driver availability. The subdevice driver then has to verify whether all
-the requirements for a successful probing are satisfied. This can include a
-check for a master clock availability. If any of the conditions aren't satisfied
-the driver might decide to return ``-EPROBE_DEFER`` to request further reprobing
-attempts. Once all conditions are met the subdevice shall be registered using
-the :c:func:`v4l2_async_register_subdev` function. Unregistration is
-performed using the :c:func:`v4l2_async_unregister_subdev` call. Subdevices
-registered this way are stored in a global list of subdevices, ready to be
-picked up by bridge drivers.
-
-Bridge drivers in turn have to register a notifier object. This is
-performed using the :c:func:`v4l2_async_notifier_register` call. To
-unregister the notifier the driver has to call
-:c:func:`v4l2_async_notifier_unregister`. The former of the two functions
-takes two arguments: a pointer to struct :c:type:`v4l2_device` and a
-pointer to struct :c:type:`v4l2_async_notifier`.
-
-Before registering the notifier, bridge drivers must do two things:
-first, the notifier must be initialized using the
-:c:func:`v4l2_async_notifier_init`. Second, bridge drivers can then
-begin to form a list of subdevice descriptors that the bridge device
-needs for its operation. Subdevice descriptors are added to the notifier
-using the :c:func:`v4l2_async_notifier_add_subdev` call. This function
-takes two arguments: a pointer to struct :c:type:`v4l2_async_notifier`,
-and a pointer to the subdevice descripter, which is of type struct
-:c:type:`v4l2_async_subdev`.
-
-The V4L2 core will then use these descriptors to match asynchronously
-registered subdevices to them. If a match is detected the ``.bound()``
-notifier callback is called. After all subdevices have been located the
-.complete() callback is called. When a subdevice is removed from the
-system the .unbind() method is called. All three callbacks are optional.
-
-V4L2 sub-device userspace API
------------------------------
-
-Beside exposing a kernel API through the :c:type:`v4l2_subdev_ops` structure,
-V4L2 sub-devices can also be controlled directly by userspace applications.
-
-Device nodes named ``v4l-subdev``\ *X* can be created in ``/dev`` to access
-sub-devices directly. If a sub-device supports direct userspace configuration
-it must set the ``V4L2_SUBDEV_FL_HAS_DEVNODE`` flag before being registered.
-
-After registering sub-devices, the :c:type:`v4l2_device` driver can create
-device nodes for all registered sub-devices marked with
-``V4L2_SUBDEV_FL_HAS_DEVNODE`` by calling
-:c:func:`v4l2_device_register_subdev_nodes`. Those device nodes will be
-automatically removed when sub-devices are unregistered.
-
-The device node handles a subset of the V4L2 API.
-
-``VIDIOC_QUERYCTRL``,
-``VIDIOC_QUERYMENU``,
-``VIDIOC_G_CTRL``,
-``VIDIOC_S_CTRL``,
-``VIDIOC_G_EXT_CTRLS``,
-``VIDIOC_S_EXT_CTRLS`` and
-``VIDIOC_TRY_EXT_CTRLS``:
-
-	The controls ioctls are identical to the ones defined in V4L2. They
-	behave identically, with the only exception that they deal only with
-	controls implemented in the sub-device. Depending on the driver, those
-	controls can be also be accessed through one (or several) V4L2 device
-	nodes.
-
-``VIDIOC_DQEVENT``,
-``VIDIOC_SUBSCRIBE_EVENT`` and
-``VIDIOC_UNSUBSCRIBE_EVENT``
-
-	The events ioctls are identical to the ones defined in V4L2. They
-	behave identically, with the only exception that they deal only with
-	events generated by the sub-device. Depending on the driver, those
-	events can also be reported by one (or several) V4L2 device nodes.
-
-	Sub-device drivers that want to use events need to set the
-	``V4L2_SUBDEV_USES_EVENTS`` :c:type:`v4l2_subdev`.flags and initialize
-	:c:type:`v4l2_subdev`.nevents to events queue depth before registering
-	the sub-device. After registration events can be queued as usual on the
-	:c:type:`v4l2_subdev`.devnode device node.
-
-	To properly support events, the ``poll()`` file operation is also
-	implemented.
-
-Private ioctls
-
-	All ioctls not in the above list are passed directly to the sub-device
-	driver through the core::ioctl operation.
-
-
-I2C sub-device drivers
-----------------------
-
-Since these drivers are so common, special helper functions are available to
-ease the use of these drivers (``v4l2-common.h``).
-
-The recommended method of adding :c:type:`v4l2_subdev` support to an I2C driver
-is to embed the :c:type:`v4l2_subdev` struct into the state struct that is
-created for each I2C device instance. Very simple devices have no state
-struct and in that case you can just create a :c:type:`v4l2_subdev` directly.
-
-A typical state struct would look like this (where 'chipname' is replaced by
-the name of the chip):
-
-.. code-block:: c
-
-	struct chipname_state {
-		struct v4l2_subdev sd;
-		...  /* additional state fields */
-	};
-
-Initialize the :c:type:`v4l2_subdev` struct as follows:
-
-.. code-block:: c
-
-	v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
-
-This function will fill in all the fields of :c:type:`v4l2_subdev` ensure that
-the :c:type:`v4l2_subdev` and i2c_client both point to one another.
-
-You should also add a helper inline function to go from a :c:type:`v4l2_subdev`
-pointer to a chipname_state struct:
-
-.. code-block:: c
-
-	static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
-	{
-		return container_of(sd, struct chipname_state, sd);
-	}
-
-Use this to go from the :c:type:`v4l2_subdev` struct to the ``i2c_client``
-struct:
-
-.. code-block:: c
-
-	struct i2c_client *client = v4l2_get_subdevdata(sd);
-
-And this to go from an ``i2c_client`` to a :c:type:`v4l2_subdev` struct:
-
-.. code-block:: c
-
-	struct v4l2_subdev *sd = i2c_get_clientdata(client);
-
-Make sure to call
-:c:func:`v4l2_device_unregister_subdev`\ (:c:type:`sd <v4l2_subdev>`)
-when the ``remove()`` callback is called. This will unregister the sub-device
-from the bridge driver. It is safe to call this even if the sub-device was
-never registered.
-
-You need to do this because when the bridge driver destroys the i2c adapter
-the ``remove()`` callbacks are called of the i2c devices on that adapter.
-After that the corresponding v4l2_subdev structures are invalid, so they
-have to be unregistered first. Calling
-:c:func:`v4l2_device_unregister_subdev`\ (:c:type:`sd <v4l2_subdev>`)
-from the ``remove()`` callback ensures that this is always done correctly.
-
-
-The bridge driver also has some helper functions it can use:
-
-.. code-block:: c
-
-	struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter,
-					"module_foo", "chipid", 0x36, NULL);
-
-This loads the given module (can be ``NULL`` if no module needs to be loaded)
-and calls :c:func:`i2c_new_device` with the given ``i2c_adapter`` and
-chip/address arguments. If all goes well, then it registers the subdev with
-the v4l2_device.
-
-You can also use the last argument of :c:func:`v4l2_i2c_new_subdev` to pass
-an array of possible I2C addresses that it should probe. These probe addresses
-are only used if the previous argument is 0. A non-zero argument means that you
-know the exact i2c address so in that case no probing will take place.
-
-Both functions return ``NULL`` if something went wrong.
-
-Note that the chipid you pass to :c:func:`v4l2_i2c_new_subdev` is usually
-the same as the module name. It allows you to specify a chip variant, e.g.
-"saa7114" or "saa7115". In general though the i2c driver autodetects this.
-The use of chipid is something that needs to be looked at more closely at a
-later date. It differs between i2c drivers and as such can be confusing.
-To see which chip variants are supported you can look in the i2c driver code
-for the i2c_device_id table. This lists all the possibilities.
-
-There are one more helper function:
-
-:c:func:`v4l2_i2c_new_subdev_board` uses an :c:type:`i2c_board_info` struct
-which is passed to the i2c driver and replaces the irq, platform_data and addr
-arguments.
-
-If the subdev supports the s_config core ops, then that op is called with
-the irq and platform_data arguments after the subdev was setup.
-
-The :c:func:`v4l2_i2c_new_subdev` function will call
-:c:func:`v4l2_i2c_new_subdev_board`, internally filling a
-:c:type:`i2c_board_info` structure using the ``client_type`` and the
-``addr`` to fill it.

-Videobuf Framework
-==================
-
-Author: Jonathan Corbet <corbet@lwn.net>
-
-Current as of 2.6.33
-
-.. note::
-
-   The videobuf framework was deprecated in favor of videobuf2. Shouldn't
-   be used on new drivers.
-
-Introduction
-------------
-
-The videobuf layer functions as a sort of glue layer between a V4L2 driver
-and user space.  It handles the allocation and management of buffers for
-the storage of video frames.  There is a set of functions which can be used
-to implement many of the standard POSIX I/O system calls, including read(),
-poll(), and, happily, mmap().  Another set of functions can be used to
-implement the bulk of the V4L2 ioctl() calls related to streaming I/O,
-including buffer allocation, queueing and dequeueing, and streaming
-control.  Using videobuf imposes a few design decisions on the driver
-author, but the payback comes in the form of reduced code in the driver and
-a consistent implementation of the V4L2 user-space API.
-
-Buffer types
-------------
-
-Not all video devices use the same kind of buffers.  In fact, there are (at
-least) three common variations:
-
- - Buffers which are scattered in both the physical and (kernel) virtual
-   address spaces.  (Almost) all user-space buffers are like this, but it
-   makes great sense to allocate kernel-space buffers this way as well when
-   it is possible.  Unfortunately, it is not always possible; working with
-   this kind of buffer normally requires hardware which can do
-   scatter/gather DMA operations.
-
- - Buffers which are physically scattered, but which are virtually
-   contiguous; buffers allocated with vmalloc(), in other words.  These
-   buffers are just as hard to use for DMA operations, but they can be
-   useful in situations where DMA is not available but virtually-contiguous
-   buffers are convenient.
-
- - Buffers which are physically contiguous.  Allocation of this kind of
-   buffer can be unreliable on fragmented systems, but simpler DMA
-   controllers cannot deal with anything else.
-
-Videobuf can work with all three types of buffers, but the driver author
-must pick one at the outset and design the driver around that decision.
-
-[It's worth noting that there's a fourth kind of buffer: "overlay" buffers
-which are located within the system's video memory.  The overlay
-functionality is considered to be deprecated for most use, but it still
-shows up occasionally in system-on-chip drivers where the performance
-benefits merit the use of this technique.  Overlay buffers can be handled
-as a form of scattered buffer, but there are very few implementations in
-the kernel and a description of this technique is currently beyond the
-scope of this document.]
-
-Data structures, callbacks, and initialization
-----------------------------------------------
-
-Depending on which type of buffers are being used, the driver should
-include one of the following files:
-
-.. code-block:: none
-
-    <media/videobuf-dma-sg.h>		/* Physically scattered */
-    <media/videobuf-vmalloc.h>		/* vmalloc() buffers	*/
-    <media/videobuf-dma-contig.h>	/* Physically contiguous */
-
-The driver's data structure describing a V4L2 device should include a
-struct videobuf_queue instance for the management of the buffer queue,
-along with a list_head for the queue of available buffers.  There will also
-need to be an interrupt-safe spinlock which is used to protect (at least)
-the queue.
-
-The next step is to write four simple callbacks to help videobuf deal with
-the management of buffers:
-
-.. code-block:: none
-
-    struct videobuf_queue_ops {
-	int (*buf_setup)(struct videobuf_queue *q,
-			 unsigned int *count, unsigned int *size);
-	int (*buf_prepare)(struct videobuf_queue *q,
-			   struct videobuf_buffer *vb,
-			   enum v4l2_field field);
-	void (*buf_queue)(struct videobuf_queue *q,
-			  struct videobuf_buffer *vb);
-	void (*buf_release)(struct videobuf_queue *q,
-			    struct videobuf_buffer *vb);
-    };
-
-buf_setup() is called early in the I/O process, when streaming is being
-initiated; its purpose is to tell videobuf about the I/O stream.  The count
-parameter will be a suggested number of buffers to use; the driver should
-check it for rationality and adjust it if need be.  As a practical rule, a
-minimum of two buffers are needed for proper streaming, and there is
-usually a maximum (which cannot exceed 32) which makes sense for each
-device.  The size parameter should be set to the expected (maximum) size
-for each frame of data.
-
-Each buffer (in the form of a struct videobuf_buffer pointer) will be
-passed to buf_prepare(), which should set the buffer's size, width, height,
-and field fields properly.  If the buffer's state field is
-VIDEOBUF_NEEDS_INIT, the driver should pass it to:
-
-.. code-block:: none
-
-    int videobuf_iolock(struct videobuf_queue* q, struct videobuf_buffer *vb,
-			struct v4l2_framebuffer *fbuf);
-
-Among other things, this call will usually allocate memory for the buffer.
-Finally, the buf_prepare() function should set the buffer's state to
-VIDEOBUF_PREPARED.
-
-When a buffer is queued for I/O, it is passed to buf_queue(), which should
-put it onto the driver's list of available buffers and set its state to
-VIDEOBUF_QUEUED.  Note that this function is called with the queue spinlock
-held; if it tries to acquire it as well things will come to a screeching
-halt.  Yes, this is the voice of experience.  Note also that videobuf may
-wait on the first buffer in the queue; placing other buffers in front of it
-could again gum up the works.  So use list_add_tail() to enqueue buffers.
-
-Finally, buf_release() is called when a buffer is no longer intended to be
-used.  The driver should ensure that there is no I/O active on the buffer,
-then pass it to the appropriate free routine(s):
-
-.. code-block:: none
-
-    /* Scatter/gather drivers */
-    int videobuf_dma_unmap(struct videobuf_queue *q,
-			   struct videobuf_dmabuf *dma);
-    int videobuf_dma_free(struct videobuf_dmabuf *dma);
-
-    /* vmalloc drivers */
-    void videobuf_vmalloc_free (struct videobuf_buffer *buf);
-
-    /* Contiguous drivers */
-    void videobuf_dma_contig_free(struct videobuf_queue *q,
-				  struct videobuf_buffer *buf);
-
-One way to ensure that a buffer is no longer under I/O is to pass it to:
-
-.. code-block:: none
-
-    int videobuf_waiton(struct videobuf_buffer *vb, int non_blocking, int intr);
-
-Here, vb is the buffer, non_blocking indicates whether non-blocking I/O
-should be used (it should be zero in the buf_release() case), and intr
-controls whether an interruptible wait is used.
-
-File operations
----------------
-
-At this point, much of the work is done; much of the rest is slipping
-videobuf calls into the implementation of the other driver callbacks.  The
-first step is in the open() function, which must initialize the
-videobuf queue.  The function to use depends on the type of buffer used:
-
-.. code-block:: none
-
-    void videobuf_queue_sg_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_vmalloc_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_dma_contig_init(struct videobuf_queue *q,
-				       struct videobuf_queue_ops *ops,
-				       struct device *dev,
-				       spinlock_t *irqlock,
-				       enum v4l2_buf_type type,
-				       enum v4l2_field field,
-				       unsigned int msize,
-				       void *priv);
-
-In each case, the parameters are the same: q is the queue structure for the
-device, ops is the set of callbacks as described above, dev is the device
-structure for this video device, irqlock is an interrupt-safe spinlock to
-protect access to the data structures, type is the buffer type used by the
-device (cameras will use V4L2_BUF_TYPE_VIDEO_CAPTURE, for example), field
-describes which field is being captured (often V4L2_FIELD_NONE for
-progressive devices), msize is the size of any containing structure used
-around struct videobuf_buffer, and priv is a private data pointer which
-shows up in the priv_data field of struct videobuf_queue.  Note that these
-are void functions which, evidently, are immune to failure.
-
-V4L2 capture drivers can be written to support either of two APIs: the
-read() system call and the rather more complicated streaming mechanism.  As
-a general rule, it is necessary to support both to ensure that all
-applications have a chance of working with the device.  Videobuf makes it
-easy to do that with the same code.  To implement read(), the driver need
-only make a call to one of:
-
-.. code-block:: none
-
-    ssize_t videobuf_read_one(struct videobuf_queue *q,
-			      char __user *data, size_t count,
-			      loff_t *ppos, int nonblocking);
-
-    ssize_t videobuf_read_stream(struct videobuf_queue *q,
-				 char __user *data, size_t count,
-				 loff_t *ppos, int vbihack, int nonblocking);
-
-Either one of these functions will read frame data into data, returning the
-amount actually read; the difference is that videobuf_read_one() will only
-read a single frame, while videobuf_read_stream() will read multiple frames
-if they are needed to satisfy the count requested by the application.  A
-typical driver read() implementation will start the capture engine, call
-one of the above functions, then stop the engine before returning (though a
-smarter implementation might leave the engine running for a little while in
-anticipation of another read() call happening in the near future).
-
-The poll() function can usually be implemented with a direct call to:
-
-.. code-block:: none
-
-    unsigned int videobuf_poll_stream(struct file *file,
-				      struct videobuf_queue *q,
-				      poll_table *wait);
-
-Note that the actual wait queue eventually used will be the one associated
-with the first available buffer.
-
-When streaming I/O is done to kernel-space buffers, the driver must support
-the mmap() system call to enable user space to access the data.  In many
-V4L2 drivers, the often-complex mmap() implementation simplifies to a
-single call to:
-
-.. code-block:: none
-
-    int videobuf_mmap_mapper(struct videobuf_queue *q,
-			     struct vm_area_struct *vma);
-
-Everything else is handled by the videobuf code.
-
-The release() function requires two separate videobuf calls:
-
-.. code-block:: none
-
-    void videobuf_stop(struct videobuf_queue *q);
-    int videobuf_mmap_free(struct videobuf_queue *q);
-
-The call to videobuf_stop() terminates any I/O in progress - though it is
-still up to the driver to stop the capture engine.  The call to
-videobuf_mmap_free() will ensure that all buffers have been unmapped; if
-so, they will all be passed to the buf_release() callback.  If buffers
-remain mapped, videobuf_mmap_free() returns an error code instead.  The
-purpose is clearly to cause the closing of the file descriptor to fail if
-buffers are still mapped, but every driver in the 2.6.32 kernel cheerfully
-ignores its return value.
-
-ioctl() operations
-------------------
-
-The V4L2 API includes a very long list of driver callbacks to respond to
-the many ioctl() commands made available to user space.  A number of these
-- those associated with streaming I/O - turn almost directly into videobuf
-calls.  The relevant helper functions are:
-
-.. code-block:: none
-
-    int videobuf_reqbufs(struct videobuf_queue *q,
-			 struct v4l2_requestbuffers *req);
-    int videobuf_querybuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_qbuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_dqbuf(struct videobuf_queue *q, struct v4l2_buffer *b,
-		       int nonblocking);
-    int videobuf_streamon(struct videobuf_queue *q);
-    int videobuf_streamoff(struct videobuf_queue *q);
-
-So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's
-vidioc_reqbufs() callback which, in turn, usually only needs to locate the
-proper struct videobuf_queue pointer and pass it to videobuf_reqbufs().
-These support functions can replace a great deal of buffer management
-boilerplate in a lot of V4L2 drivers.
-
-The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
-complex, of course, since they will also need to deal with starting and
-stopping the capture engine.
-
-Buffer allocation
------------------
-
-Thus far, we have talked about buffers, but have not looked at how they are
-allocated.  The scatter/gather case is the most complex on this front.  For
-allocation, the driver can leave buffer allocation entirely up to the
-videobuf layer; in this case, buffers will be allocated as anonymous
-user-space pages and will be very scattered indeed.  If the application is
-using user-space buffers, no allocation is needed; the videobuf layer will
-take care of calling get_user_pages() and filling in the scatterlist array.
-
-If the driver needs to do its own memory allocation, it should be done in
-the vidioc_reqbufs() function, *after* calling videobuf_reqbufs().  The
-first step is a call to:
-
-.. code-block:: none
-
-    struct videobuf_dmabuf *videobuf_to_dma(struct videobuf_buffer *buf);
-
-The returned videobuf_dmabuf structure (defined in
-<media/videobuf-dma-sg.h>) includes a couple of relevant fields:
-
-.. code-block:: none
-
-    struct scatterlist  *sglist;
-    int                 sglen;
-
-The driver must allocate an appropriately-sized scatterlist array and
-populate it with pointers to the pieces of the allocated buffer; sglen
-should be set to the length of the array.
-
-Drivers using the vmalloc() method need not (and cannot) concern themselves
-with buffer allocation at all; videobuf will handle those details.  The
-same is normally true of contiguous-DMA drivers as well; videobuf will
-allocate the buffers (with dma_alloc_coherent()) when it sees fit.  That
-means that these drivers may be trying to do high-order allocations at any
-time, an operation which is not always guaranteed to work.  Some drivers
-play tricks by allocating DMA space at system boot time; videobuf does not
-currently play well with those drivers.
-
-As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer,
-as long as that buffer is physically contiguous.  Normal user-space
-allocations will not meet that criterion, but buffers obtained from other
-kernel drivers, or those contained within huge pages, will work with these
-drivers.
-
-Filling the buffers
--------------------
-
-The final part of a videobuf implementation has no direct callback - it's
-the portion of the code which actually puts frame data into the buffers,
-usually in response to interrupts from the device.  For all types of
-drivers, this process works approximately as follows:
-
- - Obtain the next available buffer and make sure that somebody is actually
-   waiting for it.
-
- - Get a pointer to the memory and put video data there.
-
- - Mark the buffer as done and wake up the process waiting for it.
-
-Step (1) above is done by looking at the driver-managed list_head structure
-- the one which is filled in the buf_queue() callback.  Because starting
-the engine and enqueueing buffers are done in separate steps, it's possible
-for the engine to be running without any buffers available - in the
-vmalloc() case especially.  So the driver should be prepared for the list
-to be empty.  It is equally possible that nobody is yet interested in the
-buffer; the driver should not remove it from the list or fill it until a
-process is waiting on it.  That test can be done by examining the buffer's
-done field (a wait_queue_head_t structure) with waitqueue_active().
-
-A buffer's state should be set to VIDEOBUF_ACTIVE before being mapped for
-DMA; that ensures that the videobuf layer will not try to do anything with
-it while the device is transferring data.
-
-For scatter/gather drivers, the needed memory pointers will be found in the
-scatterlist structure described above.  Drivers using the vmalloc() method
-can get a memory pointer with:
-
-.. code-block:: none
-
-    void *videobuf_to_vmalloc(struct videobuf_buffer *buf);
-
-For contiguous DMA drivers, the function to use is:
-
-.. code-block:: none
-
-    dma_addr_t videobuf_to_dma_contig(struct videobuf_buffer *buf);
-
-The contiguous DMA API goes out of its way to hide the kernel-space address
-of the DMA buffer from drivers.
-
-The final step is to set the size field of the relevant videobuf_buffer
-structure to the actual size of the captured image, set state to
-VIDEOBUF_DONE, then call wake_up() on the done queue.  At this point, the
-buffer is owned by the videobuf layer and the driver should not touch it
-again.
-
-Developers who are interested in more information can go into the relevant
-header files; there are a few low-level functions declared there which have
-not been talked about here.  Also worthwhile is the vivi driver
-(drivers/media/platform/vivi.c), which is maintained as an example of how V4L2
-drivers should be written.  Vivi only uses the vmalloc() API, but it's good
-enough to get started with.  Note also that all of these calls are exported
-GPL-only, so they will not be available to non-GPL kernel modules.

-
-Synopsis
-========
-
-.. code-block:: c
-
-    #include <sys/ioctl.h>
-
-
-.. c:function:: int ioctl( int fd, int request, void *argp )
-   :name: cec-ioctl
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``request``
-    CEC ioctl request code as defined in the cec.h header file, for
-    example :ref:`CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`.
-
-``argp``
-    Pointer to a request-specific structure.
-
-
-Description
-===========
-
-The :c:func:`ioctl() <cec-ioctl>` function manipulates cec device parameters. The
-argument ``fd`` must be an open file descriptor.
-
-The ioctl ``request`` code specifies the cec function to be called. It
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes.
-
-Macros and structures definitions specifying cec ioctl requests and
-their parameters are located in the cec.h header file. All cec ioctl
-requests, their respective function and parameters are specified in
-:ref:`cec-user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-Request-specific error codes are listed in the individual requests
-descriptions.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-
-
-.. c:function:: int open( const char *device_name, int flags )

-
-
-Arguments
-=========
-
-``device_name``
-    Device to be opened.
-
-``flags``
-    Open flags. Access mode must be ``O_RDWR``.
-
-    When the ``O_NONBLOCK`` flag is given, the
-    :ref:`CEC_RECEIVE <CEC_RECEIVE>` and :ref:`CEC_DQEVENT <CEC_DQEVENT>` ioctls
-    will return the ``EAGAIN`` error code when no message or event is available, and

-    :ref:`CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` and
-    :ref:`CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-    all return 0.
-
-    Other flags have no effect.
-
-
-Description
-===========
-
-To open a cec device applications call :c:func:`open() <cec-open>` with the
-desired device name. The function has no side effects; the device
-configuration remain unchanged.
-
-When the device is opened in read-only mode, attempts to modify its
-configuration will result in an error, and ``errno`` will be set to
-EBADF.
-
-
-Return Value
-============
-
-:c:func:`open() <cec-open>` returns the new file descriptor on success. On error,
--1 is returned, and ``errno`` is set appropriately. Possible error codes
-include:
-
-``EACCES``
-    The requested access to the file is not allowed.
-
-``EMFILE``
-    The process already has the maximum number of files open.
-
-``ENFILE``
-    The system limit on the total number of open files has been reached.
-
-``ENOMEM``
-    Insufficient kernel memory was available.
-
-``ENXIO``
-    No device corresponding to this device special file exists.

-With the :c:func:`poll() <cec-poll>` function applications can wait for CEC
-events.
-
-On success :c:func:`poll() <cec-poll>` returns the number of file descriptors
-that have been selected (that is, file descriptors for which the
-``revents`` field of the respective struct :c:type:`pollfd`
-is non-zero). CEC devices set the ``POLLIN`` and ``POLLRDNORM`` flags in
-the ``revents`` field if there are messages in the receive queue. If the
-transmit queue has room for new messages, the ``POLLOUT`` and
-``POLLWRNORM`` flags are set. If there are events in the event queue,
-then the ``POLLPRI`` flag is set. When the function times out it returns
-a value of zero, on failure it returns -1 and the ``errno`` variable is
-set appropriately.
-
-For more details see the :c:func:`poll() <cec-poll>` manual page.
-
-
-Return Value
-============
-
-On success, :c:func:`poll() <cec-poll>` returns the number structures which have
-non-zero ``revents`` fields, or zero if the call timed out. On error -1
-is returned, and the ``errno`` variable is set appropriately:
-
-``EBADF``
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-``EFAULT``
-    ``ufds`` references an inaccessible memory area.
-
-``EINTR``
-    The call was interrupted by a signal.
-
-``EINVAL``
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-Introduction
-============
-
-HDMI connectors provide a single pin for use by the Consumer Electronics
-Control protocol. This protocol allows different devices connected by an
-HDMI cable to communicate. The protocol for CEC version 1.4 is defined
-in supplements 1 (CEC) and 2 (HEAC or HDMI Ethernet and Audio Return
-Channel) of the HDMI 1.4a (:ref:`hdmi`) specification and the
-extensions added to CEC version 2.0 are defined in chapter 11 of the
-HDMI 2.0 (:ref:`hdmi2`) specification.
-
-The bitrate is very slow (effectively no more than 36 bytes per second)
-and is based on the ancient AV.link protocol used in old SCART
-connectors. The protocol closely resembles a crazy Rube Goldberg
-contraption and is an unholy mix of low and high level messages. Some
-messages, especially those part of the HEAC protocol layered on top of
-CEC, need to be handled by the kernel, others can be handled either by
-the kernel or by userspace.
-
-In addition, CEC can be implemented in HDMI receivers, transmitters and
-in USB devices that have an HDMI input and an HDMI output and that
-control just the CEC pin.
-
-Drivers that support CEC will create a CEC device node (/dev/cecX) to
-give userspace access to the CEC adapter. The
-:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.
-
-In order to check the support and test it, it is suggested to download
-the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
-provides three tools to handle CEC:
-
-- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
-  and monitor CEC messages.
-
-- cec-compliance: does a CEC compliance test of a remote CEC device to
-  determine how compliant the CEC implementation is.
-
-- cec-follower: emulates a CEC follower.

-Description
-===========
-
-All cec devices must support :ref:`ioctl CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`. To query
-device information, applications call the ioctl with a pointer to a
-struct :c:type:`cec_caps`. The driver fills the structure and
-returns the information to the application. The ioctl never fails.

-
-      - ``CEC_CAP_MONITOR_PIN``
-      - 0x00000080
-      - The CEC hardware can monitor CEC pin changes from low to high voltage
-        and vice versa. When in pin monitoring mode the application will
-	receive ``CEC_EVENT_PIN_CEC_LOW`` and ``CEC_EVENT_PIN_CEC_HIGH`` events.

-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``argp``
-    Pointer to struct :c:type:`cec_log_addrs`.
-
-Description
-===========
-
-To query the current CEC logical addresses, applications call
-:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
-struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
-
-To set new logical addresses, applications fill in
-struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
-returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
-the ``EBUSY`` error code will be returned.
-
-To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
-will be ignored in that case. The adapter will go to the unconfigured state and the
-``cec_version``, ``vendor_id`` and ``osd_name`` fields are all reset to their default
-values (CEC version 2.0, no vendor ID and an empty OSD name).
-
-If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),
-then this ioctl will block until all requested logical
-addresses have been claimed. If the file descriptor is in non-blocking mode then it will
-not wait for the logical addresses to be claimed, instead it just returns 0.
-
-A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the
-logical addresses are claimed or cleared.
-
-Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when
-logical address types are already defined will return with error ``EBUSY``.

-	``CEC_LOG_ADDR_INVALID``.
-    * - __u16
-      - ``log_addr_mask``
-      - The bitmask of all logical addresses this adapter has claimed. If
-	this adapter is Unregistered then ``log_addr_mask`` sets bit 15
-	and clears all other bits. If this adapter is not configured at
-	all, then ``log_addr_mask`` is set to 0. Set by the driver.
-    * - __u8
-      - ``cec_version``
-      - The CEC version that this adapter shall use. See
-	:ref:`cec-versions`. Used to implement the
-	``CEC_MSG_CEC_VERSION`` and ``CEC_MSG_REPORT_FEATURES`` messages.
-	Note that :ref:`CEC_OP_CEC_VERSION_1_3A <CEC-OP-CEC-VERSION-1-3A>` is not allowed by the CEC
-	framework.
-    * - __u8
-      - ``num_log_addrs``
-      - Number of logical addresses to set up. Must be ≤
-	``available_log_addrs`` as returned by
-	:ref:`CEC_ADAP_G_CAPS`. All arrays in
-	this structure are only filled up to index
-	``available_log_addrs``-1. The remaining array elements will be
-	ignored. Note that the CEC 2.0 standard allows for a maximum of 2
-	logical addresses, although some hardware has support for more.
-	``CEC_MAX_LOG_ADDRS`` is 4. The driver will return the actual
-	number of logical addresses it could claim, which may be less than
-	what was requested. If this field is set to 0, then the CEC
-	adapter shall clear all claimed logical addresses and all other
-	fields will be ignored.
-    * - __u32
-      - ``vendor_id``
-      - The vendor ID is a 24-bit number that identifies the specific
-	vendor or entity. Based on this ID vendor specific commands may be
-	defined. If you do not want a vendor ID then set it to
-	``CEC_VENDOR_ID_NONE``.
-    * - __u32
-      - ``flags``
-      - Flags. See :ref:`cec-log-addrs-flags` for a list of available flags.
-    * - char
-      - ``osd_name[15]``
-      - The On-Screen Display name as is returned by the
-	``CEC_MSG_SET_OSD_NAME`` message.
-    * - __u8
-      - ``primary_device_type[CEC_MAX_LOG_ADDRS]``
-      - Primary device type for each logical address. See
-	:ref:`cec-prim-dev-types` for possible types.
-    * - __u8
-      - ``log_addr_type[CEC_MAX_LOG_ADDRS]``
-      - Logical address types. See :ref:`cec-log-addr-types` for

-	to :ref:`CEC_LOG_ADDR_TYPE_UNREGISTERED <CEC-LOG-ADDR-TYPE-UNREGISTERED>`).
-    * - __u8
-      - ``all_device_types[CEC_MAX_LOG_ADDRS]``
-      - CEC 2.0 specific: the bit mask of all device types. See
-	:ref:`cec-all-dev-types-flags`. It is used in the CEC 2.0
-	``CEC_MSG_REPORT_FEATURES`` message. For CEC 1.4 you can either leave
-	this field to 0, or fill it in according to the CEC 2.0 guidelines to
-	give the CEC framework more information about the device type, even
-	though the framework won't use it directly in the CEC message.
-    * - __u8
-      - ``features[CEC_MAX_LOG_ADDRS][12]``
-      - Features for each logical address. It is used in the CEC 2.0
-	``CEC_MSG_REPORT_FEATURES`` message. The 12 bytes include both the
-	RC Profile and the Device Features. For CEC 1.4 you can either leave
-        this field to all 0, or fill it in according to the CEC 2.0 guidelines to
-        give the CEC framework more information about the device type, even
-        though the framework won't use it directly in the CEC message.

-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``argp``
-    Pointer to the CEC address.
-
-Description
-===========
-
-To query the current physical address applications call
-:ref:`ioctl CEC_ADAP_G_PHYS_ADDR <CEC_ADAP_G_PHYS_ADDR>` with a pointer to a __u16 where the
-driver stores the physical address.
-
-To set a new physical address applications store the physical address in
-a __u16 and call :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` with a pointer to
-this integer. The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` is only available if
-``CEC_CAP_PHYS_ADDR`` is set (the ``ENOTTY`` error code will be returned
-otherwise). The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can only be called
-by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
-the ``EBUSY`` error code will be returned.
-
-To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
-The adapter will go to the unconfigured state.
-
-If logical address types have been defined (see :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`),
-then this ioctl will block until all
-requested logical addresses have been claimed. If the file descriptor is in non-blocking mode
-then it will not wait for the logical addresses to be claimed, instead it just returns 0.
-
-A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the physical address
-changes.
-
-The physical address is a 16-bit number where each group of 4 bits
-represent a digit of the physical address a.b.c.d where the most
-significant 4 bits represent 'a'. The CEC root device (usually the TV)
-has address 0.0.0.0. Every device that is hooked up to an input of the
-TV has address a.0.0.0 (where 'a' is ≥ 1), devices hooked up to those in
-turn have addresses a.b.0.0, etc. So a topology of up to 5 devices deep
-is supported. The physical address a device shall use is stored in the
-EDID of the sink.
-
-For example, the EDID for each HDMI input of the TV will have a
-different physical address of the form a.0.0.0 that the sources will
-read out and use as their physical address.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can return the following

-
-ENOTTY
-    The ``CEC_CAP_PHYS_ADDR`` capability wasn't set, so this ioctl is not supported.
-
-EBUSY
-    Another filehandle is in exclusive follower or initiator mode, or the filehandle
-    is in mode ``CEC_MODE_NO_INITIATOR``.
-
-EINVAL
-    The physical address is malformed.

-Description
-===========
-
-CEC devices can send asynchronous events. These can be retrieved by

-set errno to the ``EAGAIN`` error code.
-
-The internal event queues are per-filehandle and per-event type. If
-there is no more room in a queue then the last event is overwritten with
-the new one. This means that intermediate results can be thrown away but
-that the latest event is always available. This also means that is it
-possible to read two successive events that have the same value (e.g.
-two :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` events with
-the same state). In that case the intermediate state changes were lost but
-it is guaranteed that the state did change in between the two events.

-    Pointer to CEC mode.
-
-Description
-===========
-
-By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
-applications from stepping on each others toes it must be possible to
-obtain exclusive access to the CEC adapter. This ioctl sets the
-filehandle to initiator and/or follower mode which can be exclusive
-depending on the chosen mode. The initiator is the filehandle that is
-used to initiate messages, i.e. it commands other CEC devices. The
-follower is the filehandle that receives messages sent to the CEC
-adapter and processes them. The same filehandle can be both initiator
-and follower, or this role can be taken by two different filehandles.
-
-When a CEC message is received, then the CEC framework will decide how
-it will be processed. If the message is a reply to an earlier
-transmitted message, then the reply is sent back to the filehandle that
-is waiting for it. In addition the CEC framework will process it.
-
-If the message is not a reply, then the CEC framework will process it
-first. If there is no follower, then the message is just discarded and a
-feature abort is sent back to the initiator if the framework couldn't
-process it. If there is a follower, then the message is passed on to the
-follower who will use :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` to dequeue
-the new message. The framework expects the follower to make the right
-decisions.
-
-The CEC framework will process core messages unless requested otherwise
-by the follower. The follower can enable the passthrough mode. In that
-case, the CEC framework will pass on most core messages without
-processing them and the follower will have to implement those messages.
-There are some messages that the core will always process, regardless of
-the passthrough mode. See :ref:`cec-core-processing` for details.
-
-If there is no initiator, then any CEC filehandle can use
-:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If there is an exclusive
-initiator then only that initiator can call
-:ref:`CEC_TRANSMIT`. The follower can of course
-always call :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.

-    :name: CEC_TRANSMIT
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``argp``
-    Pointer to struct cec_msg.
-
-Description
-===========
-
-To receive a CEC message the application has to fill in the
-``timeout`` field of struct :c:type:`cec_msg` and pass it to
-:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-If the file descriptor is in non-blocking mode and there are no received
-messages pending, then it will return -1 and set errno to the ``EAGAIN``
-error code. If the file descriptor is in blocking mode and ``timeout``
-is non-zero and no message arrived within ``timeout`` milliseconds, then
-it will return -1 and set errno to the ``ETIMEDOUT`` error code.
-
-A received message can be:
-
-1. a message received from another CEC device (the ``sequence`` field will
-   be 0).
-2. the result of an earlier non-blocking transmit (the ``sequence`` field will
-   be non-zero).
-
-To send a CEC message the application has to fill in the struct
-:c:type:`cec_msg` and pass it to :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.
-The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if
-``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit
-queue, then it will return -1 and set errno to the ``EBUSY`` error code.
-The transmit queue has enough room for 18 messages (about 1 second worth
-of 2-byte messages). Note that the CEC kernel framework will also reply
-to core messages (see :ref:`cec-core-processing`), so it is not a good
-idea to fully fill up the transmit queue.
-
-If the file descriptor is in non-blocking mode then the transmit will
-return 0 and the result of the transmit will be available via
-:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` once the transmit has finished
-(including waiting for a reply, if requested).
-
-The ``sequence`` field is filled in for every transmit and this can be
-checked against the received messages to find the corresponding transmit
-result.
-
-Normally calling :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` when the physical
-address is invalid (due to e.g. a disconnect) will return ``ENONET``.
-
-However, the CEC specification allows sending messages from 'Unregistered' to
-'TV' when the physical address is invalid since some TVs pull the hotplug detect
-pin of the HDMI connector low when they go into standby, or when switching to
-another input.
-
-When the hotplug detect pin goes low the EDID disappears, and thus the
-physical address, but the cable is still connected and CEC still works.
-In order to detect/wake up the device it is allowed to send poll and 'Image/Text
-View On' messages from initiator 0xf ('Unregistered') to destination 0 ('TV').

-
-    * - __u64
-      - ``tx_ts``
-      - Timestamp in ns of when the last byte of the message was transmitted.
-	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
-	the same clock from userspace use :c:func:`clock_gettime`.
-    * - __u64
-      - ``rx_ts``
-      - Timestamp in ns of when the last byte of the message was received.
-	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
-	the same clock from userspace use :c:func:`clock_gettime`.
-    * - __u32
-      - ``len``
-      - The length of the message. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in
-	by the application. The driver will fill this in for
-	:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be
-	filled in by the driver with the length of the reply message if ``reply`` was set.
-    * - __u32
-      - ``timeout``
-      - The timeout in milliseconds. This is the time the device will wait
-	for a message to be received before timing out. If it is set to 0,
-	then it will wait indefinitely when it is called by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	If it is 0 and it is called by :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`,
-	then it will be replaced by 1000 if the ``reply`` is non-zero or
-	ignored if ``reply`` is 0.
-    * - __u32
-      - ``sequence``
-      - A non-zero sequence number is automatically assigned by the CEC framework
-	for all transmitted messages. It is used by the CEC framework when it queues
-	the transmit result (when transmit was called in non-blocking mode). This
-	allows the application to associate the received message with the original
-	transmit.
-    * - __u32
-      - ``flags``
-      - Flags. See :ref:`cec-msg-flags` for a list of available flags.
-    * - __u8
-      - ``tx_status``
-      - The status bits of the transmitted message. See
-	:ref:`cec-tx-status` for the possible status values. It is 0 if
-	this message was received, not transmitted.
-    * - __u8
-      - ``msg[16]``
-      - The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
-	application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
-	the payload of the reply message if ``timeout`` was set.
-    * - __u8
-      - ``reply``
-      - Wait until this message is replied. If ``reply`` is 0 and the
-	``timeout`` is 0, then don't wait for a reply but return after
-	transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	The case where ``reply`` is 0 (this is the opcode for the Feature Abort
-	message) and ``timeout`` is non-zero is specifically allowed to make it
-	possible to send a message and wait up to ``timeout`` milliseconds for a
-	Feature Abort reply. In this case ``rx_status`` will either be set
-	to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
-	:ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
-
-	If the transmitter message is ``CEC_MSG_INITIATE_ARC`` then the ``reply``
-	values ``CEC_MSG_REPORT_ARC_INITIATED`` and ``CEC_MSG_REPORT_ARC_TERMINATED``
-	are processed differently: either value will match both possible replies.
-	The reason is that the ``CEC_MSG_INITIATE_ARC`` message is the only CEC
-	message that has two possible replies other than Feature Abort. The
-	``reply`` field will be updated with the actual reply so that it is
-	synchronized with the contents of the received message.
-    * - __u8
-      - ``rx_status``
-      - The status bits of the received message. See
-	:ref:`cec-rx-status` for the possible status values. It is 0 if
-	this message was transmitted, not received, unless this is the
-	reply to a transmitted message. In that case both ``rx_status``
-	and ``tx_status`` are set.
-    * - __u8
-      - ``tx_status``
-      - The status bits of the transmitted message. See
-	:ref:`cec-tx-status` for the possible status values. It is 0 if
-	this message was received, not transmitted.
-    * - __u8
-      - ``tx_arb_lost_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Arbitration Lost error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_ARB_LOST <CEC-TX-STATUS-ARB-LOST>` status bit is set.
-    * - __u8
-      - ``tx_nack_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Not Acknowledged error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_NACK <CEC-TX-STATUS-NACK>` status bit is set.
-    * - __u8
-      - ``tx_low_drive_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Arbitration Lost error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_LOW_DRIVE <CEC-TX-STATUS-LOW-DRIVE>` status bit is set.
-    * - __u8
-      - ``tx_error_cnt``
-      - A counter of the number of transmit errors other than Arbitration
-	Lost or Not Acknowledged. This is only set if the hardware
-	supports this, otherwise it is always 0. This counter is only
-	valid if the :ref:`CEC_TX_STATUS_ERROR <CEC-TX-STATUS-ERROR>` status bit is set.

-      - If a CEC transmit expects a reply, then by default that reply is only sent to
-	the filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If this
-	flag is set, then the reply is also sent to all followers, if any. If the
-	filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is also a

-	then no validation takes place and the message is transmitted as-is.
-	This is useful when debugging CEC issues.
-	This flag is only allowed if the process has the ``CAP_SYS_RAWIO``
-	capability. If that is not set, then the ``EPERM`` error code is
-	returned.

-	of a transmit is just OK or FAIL. In that case this status will be
-	returned when the transmit failed.
-    * .. _`CEC-TX-STATUS-LOW-DRIVE`:
-
-      - ``CEC_TX_STATUS_LOW_DRIVE``
-      - 0x08
-      - Low drive was detected on the CEC bus. This indicates that a

-	error condition.
-    * .. _`CEC-TX-STATUS-ERROR`:
-
-      - ``CEC_TX_STATUS_ERROR``
-      - 0x10
-      - Some error occurred. This is used for any errors that do not fit

-
-      - ``CEC_TX_STATUS_MAX_RETRIES``
-      - 0x20
-      - The transmit failed after one or more retries. This status bit is

-    * .. _`CEC-TX-STATUS-ABORTED`:
-
-      - ``CEC_TX_STATUS_ABORTED``
-      - 0x40
-      - The transmit was aborted due to an HDMI disconnect, or the adapter
-        was unconfigured, or a transmit was interrupted, or the driver
-	returned an error when attempting to start a transmit.
-    * .. _`CEC-TX-STATUS-TIMEOUT`:
-
-      - ``CEC_TX_STATUS_TIMEOUT``
-      - 0x80
-      - The transmit timed out. This should not normally happen and this

-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-The :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` can return the following
-error codes:
-
-EAGAIN
-    No messages are in the receive queue, and the filehandle is in non-blocking mode.
-
-ETIMEDOUT
-    The ``timeout`` was reached while waiting for a message.
-
-ERESTARTSYS
-    The wait for a message was interrupted (e.g. by Ctrl-C).
-
-The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` can return the following
-error codes:
-
-ENOTTY
-    The ``CEC_CAP_TRANSMIT`` capability wasn't set, so this ioctl is not supported.
-
-EPERM
-    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-    has never been called, or ``CEC_MSG_FL_RAW`` was used from a process that
-    did not have the ``CAP_SYS_RAWIO`` capability.
-
-ENONET
-    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-    was called, but the physical address is invalid so no logical address was claimed.
-    An exception is made in this case for transmits from initiator 0xf ('Unregistered')
-    to destination 0 ('TV'). In that case the transmit will proceed as usual.
-
-EBUSY
-    Another filehandle is in exclusive follower or initiator mode, or the filehandle
-    is in mode ``CEC_MODE_NO_INITIATOR``. This is also returned if the transmit

-CEC Pin Framework Error Injection
-=================================
-
-The CEC Pin Framework is a core CEC framework for CEC hardware that only
-has low-level support for the CEC bus. Most hardware today will have
-high-level CEC support where the hardware deals with driving the CEC bus,
-but some older devices aren't that fancy. However, this framework also
-allows you to connect the CEC pin to a GPIO on e.g. a Raspberry Pi and
-you have now made a CEC adapter.
-
-What makes doing this so interesting is that since we have full control
-over the bus it is easy to support error injection. This is ideal to
-test how well CEC adapters can handle error conditions.
-
-Currently only the cec-gpio driver (when the CEC line is directly
-connected to a pull-up GPIO line) and the AllWinner A10/A20 drm driver
-support this framework.
-
-If ``CONFIG_CEC_PIN_ERROR_INJ`` is enabled, then error injection is available
-through debugfs. Specifically, in ``/sys/kernel/debug/cec/cecX/`` there is
-now an ``error-inj`` file.
-
-.. note::
-
-    The error injection commands are not a stable ABI and may change in the
-    future.
-
-With ``cat error-inj`` you can see both the possible commands and the current
-error injection status::
-
-	$ cat /sys/kernel/debug/cec/cec0/error-inj
-	# Clear error injections:
-	#   clear          clear all rx and tx error injections
-	#   rx-clear       clear all rx error injections
-	#   tx-clear       clear all tx error injections
-	#   <op> clear     clear all rx and tx error injections for <op>
-	#   <op> rx-clear  clear all rx error injections for <op>
-	#   <op> tx-clear  clear all tx error injections for <op>
-	#
-	# RX error injection:
-	#   <op>[,<mode>] rx-nack              NACK the message instead of sending an ACK
-	#   <op>[,<mode>] rx-low-drive <bit>   force a low-drive condition at this bit position
-	#   <op>[,<mode>] rx-add-byte          add a spurious byte to the received CEC message
-	#   <op>[,<mode>] rx-remove-byte       remove the last byte from the received CEC message
-	#   <op>[,<mode>] rx-arb-lost <poll>   generate a POLL message to trigger an arbitration lost
-	#
-	# TX error injection settings:
-	#   tx-ignore-nack-until-eom           ignore early NACKs until EOM
-	#   tx-custom-low-usecs <usecs>        define the 'low' time for the custom pulse
-	#   tx-custom-high-usecs <usecs>       define the 'high' time for the custom pulse
-	#   tx-custom-pulse                    transmit the custom pulse once the bus is idle
-	#
-	# TX error injection:
-	#   <op>[,<mode>] tx-no-eom            don't set the EOM bit
-	#   <op>[,<mode>] tx-early-eom         set the EOM bit one byte too soon
-	#   <op>[,<mode>] tx-add-bytes <num>   append <num> (1-255) spurious bytes to the message
-	#   <op>[,<mode>] tx-remove-byte       drop the last byte from the message
-	#   <op>[,<mode>] tx-short-bit <bit>   make this bit shorter than allowed
-	#   <op>[,<mode>] tx-long-bit <bit>    make this bit longer than allowed
-	#   <op>[,<mode>] tx-custom-bit <bit>  send the custom pulse instead of this bit

-	#   <op>[,<mode>] tx-long-start        send a start pulse that's too long
-	#   <op>[,<mode>] tx-custom-start      send the custom pulse instead of the start pulse
-	#   <op>[,<mode>] tx-last-bit <bit>    stop sending after this bit
-	#   <op>[,<mode>] tx-low-drive <bit>   force a low-drive condition at this bit position
-	#

-	# <bit>      CEC message bit (0-159)
-	#            10 bits per 'byte': bits 0-7: data, bit 8: EOM, bit 9: ACK
-	# <poll>     CEC poll message used to test arbitration lost (0x00-0xff, default 0x0f)
-	# <usecs>    microseconds (0-10000000, default 1000)
-
-	clear
-
-You can write error injection commands to ``error-inj`` using
-``echo 'cmd' >error-inj`` or ``cat cmd.txt >error-inj``. The ``cat error-inj``
-output contains the current error commands. You can save the output to a file
-and use it as an input to ``error-inj`` later.
-
-Basic Syntax
-------------
-
-Leading spaces/tabs are ignored. If the next character is a ``#`` or the end
-of the line was reached, then the whole line is ignored. Otherwise a command
-is expected.
-
-The error injection commands fall in two main groups: those relating to
-receiving CEC messages and those relating to transmitting CEC messages. In
-addition, there are commands to clear existing error injection commands and
-to create custom pulses on the CEC bus.
-
-Most error injection commands can be executed for specific CEC opcodes or for
-all opcodes (``any``). Each command also has a 'mode' which can be ``off``
-(can be used to turn off an existing error injection command), ``once``
-(the default) which will trigger the error injection only once for the next
-received or transmitted message, ``always`` to always trigger the error
-injection and ``toggle`` to toggle the error injection on or off for every
-transmit or receive.
-
-So '``any rx-nack``' will NACK the next received CEC message,
-'``any,always rx-nack``' will NACK all received CEC messages and
-'``0x82,toggle rx-nack``' will only NACK if an Active Source message was
-received and do that only for every other received message.
-
-After an error was injected with mode ``once`` the error injection command
-is cleared automatically, so ``once`` is a one-time deal.
-
-All combinations of ``<op>`` and error injection commands can co-exist. So
-this is fine::
-
-	0x9e tx-add-bytes 1
-	0x9e tx-early-eom
-	0x9f tx-add-bytes 2
-	any rx-nack
-
-All four error injection commands will be active simultaneously.
-
-However, if the same ``<op>`` and command combination is specified,
-but with different arguments::
-
-	0x9e tx-add-bytes 1
-	0x9e tx-add-bytes 2
-
-Then the second will overwrite the first.
-
-Clear Error Injections
-----------------------
-
-``clear``
-    Clear all error injections.
-
-``rx-clear``
-    Clear all receive error injections
-
-``tx-clear``
-    Clear all transmit error injections
-
-``<op> clear``
-    Clear all error injections for the given opcode.
-
-``<op> rx-clear``
-    Clear all receive error injections for the given opcode.
-
-``<op> tx-clear``
-    Clear all transmit error injections for the given opcode.
-
-Receive Messages
-----------------
-
-``<op>[,<mode>] rx-nack``
-    NACK broadcast messages and messages directed to this CEC adapter.
-    Every byte of the message will be NACKed in case the transmitter
-    keeps transmitting after the first byte was NACKed.
-
-``<op>[,<mode>] rx-low-drive <bit>``
-    Force a Low Drive condition at this bit position. If <op> specifies
-    a specific CEC opcode then the bit position must be at least 18,
-    otherwise the opcode hasn't been received yet. This tests if the
-    transmitter can handle the Low Drive condition correctly and reports
-    the error correctly. Note that a Low Drive in the first 4 bits can also
-    be interpreted as an Arbitration Lost condition by the transmitter.
-    This is implementation dependent.
-
-``<op>[,<mode>] rx-add-byte``
-    Add a spurious 0x55 byte to the received CEC message, provided
-    the message was 15 bytes long or less. This is useful to test
-    the high-level protocol since spurious bytes should be ignored.
-
-``<op>[,<mode>] rx-remove-byte``
-    Remove the last byte from the received CEC message, provided it
-    was at least 2 bytes long. This is useful to test the high-level
-    protocol since messages that are too short should be ignored.
-
-``<op>[,<mode>] rx-arb-lost <poll>``
-    Generate a POLL message to trigger an Arbitration Lost condition.
-    This command is only allowed for ``<op>`` values of ``next`` or ``all``.
-    As soon as a start bit has been received the CEC adapter will switch
-    to transmit mode and it will transmit a POLL message. By default this is
-    0x0f, but it can also be specified explicitly via the ``<poll>`` argument.
-
-    This command can be used to test the Arbitration Lost condition in
-    the remote CEC transmitter. Arbitration happens when two CEC adapters
-    start sending a message at the same time. In that case the initiator
-    with the most leading zeroes wins and the other transmitter has to
-    stop transmitting ('Arbitration Lost'). This is very hard to test,
-    except by using this error injection command.
-
-    This does not work if the remote CEC transmitter has logical address
-    0 ('TV') since that will always win.
-
-Transmit Messages
------------------
-
-``tx-ignore-nack-until-eom``
-    This setting changes the behavior of transmitting CEC messages. Normally
-    as soon as the receiver NACKs a byte the transmit will stop, but the
-    specification also allows that the full message is transmitted and only
-    at the end will the transmitter look at the ACK bit. This is not
-    recommended behavior since there is no point in keeping the CEC bus busy
-    for longer than is strictly needed. Especially given how slow the bus is.
-
-    This setting can be used to test how well a receiver deals with
-    transmitters that ignore NACKs until the very end of the message.
-
-``<op>[,<mode>] tx-no-eom``
-    Don't set the EOM bit. Normally the last byte of the message has the EOM
-    (End-Of-Message) bit set. With this command the transmit will just stop
-    without ever sending an EOM. This can be used to test how a receiver
-    handles this case. Normally receivers have a time-out after which
-    they will go back to the Idle state.
-
-``<op>[,<mode>] tx-early-eom``
-    Set the EOM bit one byte too soon. This obviously only works for messages
-    of two bytes or more. The EOM bit will be set for the second-to-last byte
-    and not for the final byte. The receiver should ignore the last byte in
-    this case. Since the resulting message is likely to be too short for this
-    same reason the whole message is typically ignored. The receiver should be
-    in Idle state after the last byte was transmitted.
-
-``<op>[,<mode>] tx-add-bytes <num>``
-    Append ``<num>`` (1-255) spurious bytes to the message. The extra bytes
-    have the value of the byte position in the message. So if you transmit a
-    two byte message (e.g. a Get CEC Version message) and add 2 bytes, then
-    the full message received by the remote CEC adapter is
-    ``0x40 0x9f 0x02 0x03``.
-
-    This command can be used to test buffer overflows in the receiver. E.g.
-    what does it do when it receives more than the maximum message size of 16
-    bytes.
-
-``<op>[,<mode>] tx-remove-byte``
-    Drop the last byte from the message, provided the message is at least
-    two bytes long. The receiver should ignore messages that are too short.
-
-``<op>[,<mode>] tx-short-bit <bit>``
-    Make this bit period shorter than allowed. The bit position cannot be
-    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
-    must be at least 18, otherwise the opcode hasn't been received yet.
-    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
-    With this command the period of this bit is 1.8 milliseconds, this is
-    done by reducing the time the CEC bus is high. This bit period is less
-    than is allowed and the receiver should respond with a Low Drive
-    condition.
-
-    This command is ignored for 0 bits in bit positions 0 to 3. This is
-    because the receiver also looks for an Arbitration Lost condition in
-    those first four bits and it is undefined what will happen if it
-    sees a too-short 0 bit.
-
-``<op>[,<mode>] tx-long-bit <bit>``
-    Make this bit period longer than is valid. The bit position cannot be
-    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
-    must be at least 18, otherwise the opcode hasn't been received yet.
-    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
-    With this command the period of this bit is 2.9 milliseconds, this is
-    done by increasing the time the CEC bus is high.
-
-    Even though this bit period is longer than is valid it is undefined what
-    a receiver will do. It might just accept it, or it might time out and
-    return to Idle state. Unfortunately the CEC specification is silent about
-    this.
-
-    This command is ignored for 0 bits in bit positions 0 to 3. This is
-    because the receiver also looks for an Arbitration Lost condition in
-    those first four bits and it is undefined what will happen if it
-    sees a too-long 0 bit.
-
-``<op>[,<mode>] tx-short-start``
-    Make this start bit period shorter than allowed. Normally the period of
-    a start bit is between 4.3 and 4.7 milliseconds. With this command the
-    period of the start bit is 4.1 milliseconds, this is done by reducing
-    the time the CEC bus is high. This start bit period is less than is
-    allowed and the receiver should return to Idle state when this is detected.
-
-``<op>[,<mode>] tx-long-start``
-    Make this start bit period longer than is valid. Normally the period of
-    a start bit is between 4.3 and 4.7 milliseconds. With this command the
-    period of the start bit is 5 milliseconds, this is done by increasing
-    the time the CEC bus is high. This start bit period is more than is
-    valid and the receiver should return to Idle state when this is detected.
-
-    Even though this start bit period is longer than is valid it is undefined
-    what a receiver will do. It might just accept it, or it might time out and
-    return to Idle state. Unfortunately the CEC specification is silent about
-    this.
-
-``<op>[,<mode>] tx-last-bit <bit>``
-    Just stop transmitting after this bit.  If <op> specifies a specific CEC
-    opcode then the bit position must be at least 18, otherwise the opcode
-    hasn't been received yet. This command can be used to test how the receiver
-    reacts when a message just suddenly stops. It should time out and go back
-    to Idle state.
-
-``<op>[,<mode>] tx-low-drive <bit>``
-    Force a Low Drive condition at this bit position. If <op> specifies a
-    specific CEC opcode then the bit position must be at least 18, otherwise
-    the opcode hasn't been received yet. This can be used to test how the
-    receiver handles Low Drive conditions. Note that if this happens at bit
-    positions 0-3 the receiver can interpret this as an Arbitration Lost
-    condition. This is implementation dependent.
-
-Custom Pulses
--------------
-
-``tx-custom-low-usecs <usecs>``
-    This defines the duration in microseconds that the custom pulse pulls
-    the CEC line low. The default is 1000 microseconds.
-
-``tx-custom-high-usecs <usecs>``
-    This defines the duration in microseconds that the custom pulse keeps the
-    CEC line high (unless another CEC adapter pulls it low in that time).
-    The default is 1000 microseconds. The total period of the custom pulse is
-    ``tx-custom-low-usecs + tx-custom-high-usecs``.
-
-``<op>[,<mode>] tx-custom-bit <bit>``
-    Send the custom bit instead of a regular data bit. The bit position cannot
-    be an Ack bit.  If <op> specifies a specific CEC opcode then the bit
-    position must be at least 18, otherwise the opcode hasn't been received yet.
-
-``<op>[,<mode>] tx-custom-start``
-    Send the custom bit instead of a regular start bit.
-
-``tx-custom-pulse``
-    Transmit a single custom pulse as soon as the CEC bus is idle.

-Description
------------
-
-This system call opens a named audio device (e.g.
-/dev/dvb/adapter0/audio0) for subsequent use. When an open() call has
-succeeded, the device will be ready for use. The significance of
-blocking or non-blocking mode is described in the documentation for
-functions where there is a difference. It does not affect the semantics
-of the open() call itself. A device opened in blocking mode can later be
-put into non-blocking mode (and vice versa) using the F_SETFL command
-of the fcntl system call. This is a standard system call, documented in
-the Linux manual page for fcntl. Only one user can open the Audio Device
-in O_RDWR mode. All other attempts to open the device in this mode will
-fail, and an error code will be returned. If the Audio Device is opened
-in O_RDONLY mode, the only ioctl call that can be used is
-AUDIO_GET_STATUS. All other call will return with an error code.

-          FALSE: Bypass is enabled
-
-
-Description
------------
-
-This ioctl call asks the Audio Device to bypass the Audio decoder and
-forward the stream without decoding. This mode shall be used if streams
-that can’t be handled by the Digital TV system shall be decoded. Dolby
-DigitalTM streams are automatically forwarded by the Digital TV subsystem if
-the hardware can handle it.
-
-
-Return Value
-------------
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-The Digital TV audio device controls the MPEG2 audio decoder of the Digital
-TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
-types and and ioctl definitions can be accessed by including
-``linux/dvb/audio.h`` in your application.
-
-Please note that some Digital TV cards don’t have their own MPEG decoder, which
-results in the omission of the audio and video device.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-AUDIO_SOURCE_MEMORY is selected the stream comes from the application
-through the ``write()`` system call.
-
-
-.. c:type:: audio_play_state

-
-    -  - ``O_NONBLOCK``
-       - open in non-blocking mode
-         (blocking mode is the default)
-
-
-Description
------------
-
-This system call opens a named ca device (e.g. ``/dev/dvb/adapter?/ca?``)
-for subsequent use.
-
-When an ``open()`` call has succeeded, the device will be ready for use. The
-significance of blocking or non-blocking mode is described in the
-documentation for functions where there is a difference. It does not
-affect the semantics of the ``open()`` call itself. A device opened in
-blocking mode can later be put into non-blocking mode (and vice versa)
-using the ``F_SETFL`` command of the ``fcntl`` system call. This is a
-standard system call, documented in the Linux manual page for fcntl.
-Only one user can open the CA Device in ``O_RDWR`` mode. All other
-attempts to open the device in this mode will fail, and an error code
-will be returned.
-
-
-Return Value
-------------
-
-
-On success 0 is returned.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.
-
-Generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-DMX_EXPBUF - Export a buffer as a DMABUF file descriptor.
-
-.. warning:: this API is still experimental
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, DMX_EXPBUF, struct dmx_exportbuffer *argp )
-    :name: DMX_EXPBUF
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_exportbuffer`.
-
-
-Description
-===========
-
-This ioctl is an extension to the memory mapping I/O method.
-It can be used to export a buffer as a DMABUF file at any time after
-buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
-
-To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
-Applications must set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
-(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
-Additional flags may be posted in the ``flags`` field. Refer to a manual
-for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
-and O_RDWR are supported.
-All other fields must be set to zero. In the
-case of multi-planar API, every plane is exported separately using
-multiple :ref:`DMX_EXPBUF` calls.
-
-After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
-driver, on success. This is a DMABUF file descriptor. The application may
-pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
-file when it is no longer used to allow the associated memory to be reclaimed.
-
-
-Examples
-========
-
-
-.. code-block:: c
-
-    int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
-    {
-	struct dmx_exportbuffer expbuf;
-
-	memset(&expbuf, 0, sizeof(expbuf));
-	expbuf.type = bt;
-	expbuf.index = index;
-	if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
-	    perror("DMX_EXPBUF");
-	    return -1;
-	}
-
-	*dmafd = expbuf.fd;
-
-	return 0;
-    }
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    A queue is not in MMAP mode or DMABUF exporting is not supported or
-    ``flags`` or ``index`` fields are invalid.

-dmx-mmap - Map device memory into application address space
-
-.. warning:: this API is still experimental
-
-Synopsis
-========
-
-.. code-block:: c
-
-    #include <unistd.h>
-    #include <sys/mman.h>
-
-
-.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
-    :name: dmx-mmap
-
-Arguments
-=========
-
-``start``
-    Map the buffer to this address in the application's address space.
-    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
-    multiple of the pagesize and mmap will fail when the specified
-    address cannot be used. Use of this option is discouraged;
-    applications should just specify a ``NULL`` pointer here.
-
-``length``
-    Length of the memory area to map. This must be a multiple of the
-    DVB packet length (188, on most drivers).
-
-``prot``
-    The ``prot`` argument describes the desired memory protection.
-    Regardless of the device type and the direction of data exchange it
-    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
-    and write access to image buffers. Drivers should support at least
-    this combination of flags.
-
-``flags``
-    The ``flags`` parameter specifies the type of the mapped object,
-    mapping options and whether modifications made to the mapped copy of
-    the page are private to the process or are to be shared with other
-    references.
-
-    ``MAP_FIXED`` requests that the driver selects no other address than
-    the one specified. If the specified address cannot be used,
-    :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
-    ``start`` must be a multiple of the pagesize. Use of this option is
-    discouraged.
-
-    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
-    ``MAP_SHARED`` allows applications to share the mapped memory with
-    other (e. g. child-) processes.
-
-    .. note::
-
-       The Linux Digital TV applications should not set the
-       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
-       flags.
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``offset``
-    Offset of the buffer in device memory, as returned by
-    :ref:`DMX_QUERYBUF` ioctl.
-
-
-Description
-===========
-
-The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
-``offset`` in the memory of the device specified by ``fd`` into the
-application address space, preferably at address ``start``. This latter
-address is a hint only, and is usually specified as 0.
-
-Suitable length and offset parameters are queried with the
-:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
-:ref:`DMX_REQBUFS` ioctl before they can be queried.
-
-To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
-
-
-Return Value
-============
-
-On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
-error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
-appropriately. Possible error codes are:
-
-EBADF
-    ``fd`` is not a valid file descriptor.
-
-EACCES
-    ``fd`` is not open for reading and writing.
-
-EINVAL
-    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
-    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
-
-    The ``flags`` or ``prot`` value is not supported.
-
-    No buffers have been allocated with the
-    :ref:`DMX_REQBUFS` ioctl.
-
-ENOMEM
-    Not enough physical or virtual memory was available to complete the
-    request.

-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_buffer`.
-
-
-Description
-===========
-
-Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
-(capturing) or filled (output) buffer in the driver's incoming queue.
-The semantics depend on the selected I/O method.
-
-To enqueue a buffer applications set the ``index`` field. Valid index
-numbers range from zero to the number of buffers allocated with
-:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
-one. The contents of the struct :c:type:`dmx_buffer` returned
-by a :ref:`DMX_QUERYBUF` ioctl will do as well.
-
-When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
-memory pages of the buffer in physical memory, so they cannot be swapped
-out to disk. Buffers remain locked until dequeued, until the
-the device is closed.
-
-Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
-(capturing) buffer from the driver's outgoing queue.
-They just set the ``index`` field with the buffer ID to be queued.
-When ``DMX_DQBUF`` is called with a pointer to struct :c:type:`dmx_buffer`,
-the driver fills the remaining fields or returns an error code.
-
-By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
-queue. When the ``O_NONBLOCK`` flag was given to the
-:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
-immediately with an ``EAGAIN`` error code when no buffer is available.
-
-The struct :c:type:`dmx_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EAGAIN
-    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
-    buffer was in the outgoing queue.
-
-EINVAL
-    The ``index`` is out of bounds, or no buffers have been allocated yet.
-
-EIO
-    ``DMX_DQBUF`` failed due to an internal error. Can also indicate
-    temporary problems like signal loss or CRC errors.

-DMX_REQBUFS - Initiate Memory Mapping and/or DMA buffer I/O
-
-.. warning:: this API is still experimental
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, DMX_REQBUFS, struct dmx_requestbuffers *argp )
-    :name: DMX_REQBUFS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_requestbuffers`.
-
-Description
-===========
-
-This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
-
-Memory mapped buffers are located in device memory and must be allocated
-with this ioctl before they can be mapped into the application's address
-space. User buffers are allocated by applications themselves, and this
-ioctl is merely used to switch the driver into user pointer I/O mode and
-to setup some internal structures. Similarly, DMABUF buffers are
-allocated by applications through a device driver, and this ioctl only
-configures the driver into DMABUF I/O mode without performing any direct
-allocation.
-
-To allocate device buffers applications initialize all fields of the
-struct :c:type:`dmx_requestbuffers` structure. They set the  ``count`` field
-to the desired number of buffers,  and ``size`` to the size of each
-buffer.
-
-When the ioctl is called with a pointer to this structure, the driver will
-attempt to allocate the requested number of buffers and it stores the actual
-number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
-number is also possible when the driver requires more buffers to
-function correctly. The actual allocated buffer size can is returned
-at ``size``, and can be smaller than what's requested.
-
-When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
-error code.
-
-Applications can call :ref:`DMX_REQBUFS` again to change the number of
-buffers, however this cannot succeed when any buffers are still mapped.
-A ``count`` value of zero frees all buffers, after aborting or finishing
-any DMA in progress.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EOPNOTSUPP
-    The  the requested I/O method is not supported.

-
-This ioctl call sets up a filter according to the filter and mask

-be a ”one-shot” filter, i.e. if the filtering operation should be
-stopped after the first section is received, and whether the filtering

-
-*******************
-frontend parameters
-*******************
-
-The kind of parameters passed to the frontend device for tuning depend
-on the kind of hardware you are using.
-
-The struct ``dvb_frontend_parameters`` uses a union with specific
-per-system parameters. However, as newer delivery systems required more
-data, the structure size weren't enough to fit, and just extending its
-size would break the existing applications. So, those parameters were
-replaced by the usage of
-:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
-ioctl's. The new API is flexible enough to add new parameters to
-existing delivery systems, and to add newer delivery systems.
-
-So, newer applications should use
-:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
-instead, in order to be able to support the newer System Delivery like
-DVB-S2, DVB-T2, DVB-C2, ISDB, etc.
-
-All kinds of parameters are combined as a union in the
-``dvb_frontend_parameters`` structure:
-
-
-.. code-block:: c
-
-    struct dvb_frontend_parameters {
-	uint32_t frequency;     /* (absolute) frequency in Hz for QAM/OFDM */
-		    /* intermediate frequency in kHz for QPSK */
-	fe_spectral_inversion_t inversion;
-	union {
-	    struct dvb_qpsk_parameters qpsk;
-	    struct dvb_qam_parameters  qam;
-	    struct dvb_ofdm_parameters ofdm;
-	    struct dvb_vsb_parameters  vsb;
-	} u;
-    };
-
-In the case of QPSK frontends the ``frequency`` field specifies the
-intermediate frequency, i.e. the offset which is effectively added to
-the local oscillator frequency (LOF) of the LNB. The intermediate
-frequency has to be specified in units of kHz. For QAM and OFDM
-frontends the ``frequency`` specifies the absolute frequency and is
-given in Hz.
-
-
-.. c:type:: dvb_qpsk_parameters
-
-QPSK parameters
-===============
-
-For satellite QPSK frontends you have to use the ``dvb_qpsk_parameters``
-structure:
-
-
-.. code-block:: c
-
-     struct dvb_qpsk_parameters {
-	 uint32_t        symbol_rate;  /* symbol rate in Symbols per second */
-	 fe_code_rate_t  fec_inner;    /* forward error correction (see above) */
-     };
-
-
-.. c:type:: dvb_qam_parameters
-
-QAM parameters
-==============
-
-for cable QAM frontend you use the ``dvb_qam_parameters`` structure:
-
-
-.. code-block:: c
-
-     struct dvb_qam_parameters {
-	 uint32_t         symbol_rate; /* symbol rate in Symbols per second */
-	 fe_code_rate_t   fec_inner;   /* forward error correction (see above) */
-	 fe_modulation_t  modulation;  /* modulation type (see above) */
-     };
-
-
-.. c:type:: dvb_vsb_parameters
-
-VSB parameters
-==============
-
-ATSC frontends are supported by the ``dvb_vsb_parameters`` structure:

-Part II - Digital TV API
-########################
-
-.. note::
-
-   This API is also known as Linux **DVB API**.
-
-   It it was originally written to support the European digital TV
-   standard (DVB), and later extended to support all digital TV standards.
-
-   In order to avoid confusion, within this document, it was opted to refer to
-   it, and to associated hardware as **Digital TV**.
-
-   The word **DVB** is reserved to be used for:
-
-     - the Digital TV API version
-       (e. g. DVB API version 3 or DVB API version 5);
-     - digital TV data types (enums, structs, defines, etc);
-     - digital TV device nodes (``/dev/dvb/...``);
-     - the European DVB standard.

-
-Tuning into a Digital TV physical channel and starting decoding it
-requires changing a set of parameters, in order to control the tuner,
-the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
-antenna subsystem via Satellite Equipment Control - SEC (on satellite
-systems). The actual parameters are specific to each particular digital
-TV standards, and may change as the digital TV specs evolves.
-
-In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
-union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
-ATSC delivery systems grouped there. The problem is that, as the second
-generation standards appeared, the size of such union was not big
-enough to group the structs that would be required for those new
-standards. Also, extending it would break userspace.
-
-So, the legacy union/struct based approach was deprecated, in favor
-of a properties set approach. On such approach,
-:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
-to setup the frontend and read its status.
-
-The actual action is determined by a set of dtv_property cmd/data pairs.
-With one single ioctl, is possible to get/set up to 64 properties.
-
-This section describes the new and recommended way to set the frontend,
-with supports all digital TV delivery systems.
-
-.. note::
-
-   1. On Linux DVB API version 3, setting a frontend was done via
-      struct :c:type:`dvb_frontend_parameters`.
-
-   2. Don't use DVB API version 3 calls on hardware with supports
-      newer standards. Such API provides no support or a very limited
-      support to new standards and/or new hardware.
-
-   3. Nowadays, most frontends support multiple delivery systems.
-      Only with DVB API version 5 calls it is possible to switch between
-      the multiple delivery systems supported by a frontend.
-
-   4. DVB API version 5 is also called *S2API*, as the first
-      new standard added to it was DVB-S2.
-
-**Example**: in order to set the hardware to tune into a DVB-C channel
-at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
-Mbauds, those properties should be sent to
-:ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` ioctl:
-
-  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` = SYS_DVBC_ANNEX_A
-
-  :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` = 651000000
-
-  :ref:`DTV_MODULATION <DTV-MODULATION>` = QAM_256
-
-  :ref:`DTV_INVERSION <DTV-INVERSION>` = INVERSION_AUTO
-
-  :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>` = 5217000
-
-  :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` = FEC_3_4
-
-  :ref:`DTV_TUNE <DTV-TUNE>`
-
-The code that would that would do the above is show in
-:ref:`dtv-prop-example`.

-.. attention:: While it is possible to directly call the Kernel code like the
-   above example, it is strongly recommended to use
-   `libdvbv5 <https://linuxtv.org/docs/libdvbv5/index.html>`__, as it
-   provides abstraction to work with the supported digital TV standards and
-   provides methods for usual operations like program scanning and to
-   read/write channel descriptor files.

-
-   -  This call requires read/write access to the device.
-
-.. note::
-
-   At return, the values aren't updated to reflect the actual
-   parameters used. If the actual parameters are needed, an explicit
-   call to ``FE_GET_PROPERTY`` is needed.
-
--  ``FE_GET_PROPERTY:``
-
-   -  This ioctl is used to get properties and statistics from the
-      frontend.
-
-   -  No properties are changed, and statistics aren't reset.
-
-   -  This call only requires read-only access to the device.

-This ioctl is used to set the generation of the continuous 22kHz tone.
-This call requires read/write permissions.
-
-Usually, satellite antenna subsystems require that the digital TV device
-to send a 22kHz tone in order to select between high/low band on some

-this is done using the DiSEqC ioctls.
-
-.. attention:: If more than one device is connected to the same antenna,
-   setting a tone may interfere on other devices, as they may lose the
-   capability of selecting the band. So, it is recommended that applications
-   would change to SEC_TONE_OFF when the device is not used.

-
-Name
-====
-
-FE_SET_VOLTAGE - Allow setting the DC level sent to the antenna subsystem.
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, FE_SET_VOLTAGE, enum fe_sec_voltage voltage )
-    :name: FE_SET_VOLTAGE
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <frontend_f_open>`.
-
-``voltage``
-    an integer enumered value described at :c:type:`fe_sec_voltage`
-
-
-Description
-===========
-
-This ioctl allows to set the DC voltage level sent through the antenna
-cable to 13V, 18V or off.
-
-Usually, a satellite antenna subsystems require that the digital TV
-device to send a DC voltage to feed power to the LNBf. Depending on the
-LNBf type, the polarization or the intermediate frequency (IF) of the
-LNBf can controlled by the voltage level. Other devices (for example,
-the ones that implement DISEqC and multipoint LNBf's don't need to
-control the voltage level, provided that either 13V or 18V is sent to
-power up the LNBf.
-
-.. attention:: if more than one device is connected to the same antenna,
-   setting a voltage level may interfere on other devices, as they may lose
-   the capability of setting polarization or IF. So, on those cases, setting
-   the voltage to SEC_VOLTAGE_OFF while the device is not is used is
-   recommended.
-
-
-Return Value
-============
-
-On success 0 is returned.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.
-
-Generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Digital TV property parameters
-******************************
-
-There are several different Digital TV parameters that can be used by
-:ref:`FE_SET_PROPERTY and FE_GET_PROPERTY ioctls<FE_GET_PROPERTY>`.
-This section describes each of them. Please notice, however, that only
-a subset of them are needed to setup a frontend.
-
-
-.. _DTV-UNDEFINED:
-
-DTV_UNDEFINED
-=============
-
-Used internally. A GET/SET operation for it won't change or return
-anything.
-
-
-.. _DTV-TUNE:

-DTV_CLEAR
-=========
-

-
-
-.. _DTV-FREQUENCY:
-
-DTV_FREQUENCY
-=============
-
-Frequency of the digital TV transponder/channel.
-
-.. note::
-
-  #. For satellite delivery systems, the frequency is in kHz.
-
-  #. For cable and terrestrial delivery systems, the frequency is in
-     Hz.
-
-  #. On most delivery systems, the frequency is the center frequency
-     of the transponder/channel. The exception is for ISDB-T, where
-     the main carrier has a 1/7 offset from the center.
-
-  #. For ISDB-T, the channels are usually transmitted with an offset of
-     about 143kHz. E.g. a valid frequency could be 474,143 kHz. The
-     stepping is  bound to the bandwidth of the channel which is
-     typically 6MHz.
-
-  #. In ISDB-Tsb, the channel consists of only one or three segments the
-     frequency step is 429kHz, 3*429 respectively.
-
-
-.. _DTV-MODULATION:
-
-DTV_MODULATION
-==============
-
-Specifies the frontend modulation type for delivery systems that
-supports more multiple modulations.
-
-The modulation can be one of the types defined by enum :c:type:`fe_modulation`.
-
-Most of the digital TV standards offers more than one possible
-modulation type.
-
-The table below presents a summary of the types of modulation types
-supported by each delivery system, as currently defined by specs.
-
-======================= =======================================================
-Standard		Modulation types
-======================= =======================================================
-ATSC (version 1)	8-VSB and 16-VSB.
-DMTB			4-QAM, 16-QAM, 32-QAM, 64-QAM and 4-QAM-NR.
-DVB-C Annex A/C		16-QAM, 32-QAM, 64-QAM and 256-QAM.
-DVB-C Annex B		64-QAM.
-DVB-T			QPSK, 16-QAM and 64-QAM.
-DVB-T2			QPSK, 16-QAM, 64-QAM and 256-QAM.
-DVB-S			No need to set. It supports only QPSK.
-DVB-S2			QPSK, 8-PSK, 16-APSK and 32-APSK.
-ISDB-T			QPSK, DQPSK, 16-QAM and 64-QAM.
-ISDB-S			8-PSK, QPSK and BPSK.
-======================= =======================================================
-
-.. note::
-
-   Please notice that some of the above modulation types may not be
-   defined currently at the Kernel. The reason is simple: no driver
-   needed such definition yet.
-
-
-.. _DTV-BANDWIDTH-HZ:
-
-DTV_BANDWIDTH_HZ
-================
-
-Bandwidth for the channel, in HZ.
-
-Should be set only for terrestrial delivery systems.
-
-Possible values: ``1712000``, ``5000000``, ``6000000``, ``7000000``,
-``8000000``, ``10000000``.
-
-======================= =======================================================
-Terrestrial Standard	Possible values for bandwidth
-======================= =======================================================
-ATSC (version 1)	No need to set. It is always 6MHz.
-DMTB			No need to set. It is always 8MHz.
-DVB-T			6MHz, 7MHz and 8MHz.
-DVB-T2			1.172 MHz, 5MHz, 6MHz, 7MHz, 8MHz and 10MHz
-ISDB-T			5MHz, 6MHz, 7MHz and 8MHz, although most places
-			use 6MHz.
-======================= =======================================================
-
-
-.. note::
-
-
-  #. For ISDB-Tsb, the bandwidth can vary depending on the number of
-     connected segments.
-
-     It can be easily derived from other parameters
-     (DTV_ISDBT_SB_SEGMENT_IDX, DTV_ISDBT_SB_SEGMENT_COUNT).
-
-  #. On Satellite and Cable delivery systems, the bandwidth depends on
-     the symbol rate. So, the Kernel will silently ignore any setting
-     :ref:`DTV-BANDWIDTH-HZ`. I will however fill it back with a
-     bandwidth estimation.
-
-     Such bandwidth estimation takes into account the symbol rate set with
-     :ref:`DTV-SYMBOL-RATE`, and the rolloff factor, with is fixed for
-     DVB-C and DVB-S.
-
-     For DVB-S2, the rolloff should also be set via :ref:`DTV-ROLLOFF`.
-
-
-.. _DTV-INVERSION:

-Used on satellite delivery systems.
-
-The voltage is usually used with non-DiSEqC capable LNBs to switch the
-polarzation (horizontal/vertical). When using DiSEqC epuipment this
-voltage has to be switched consistently to the DiSEqC commands as
-described in the DiSEqC spec.

-.. _DTV-ISDBT-PARTIAL-RECEPTION:
-
-DTV_ISDBT_PARTIAL_RECEPTION
-===========================
-
-Used only on ISDB.
-
-If ``DTV_ISDBT_SOUND_BROADCASTING`` is '0' this bit-field represents
-whether the channel is in partial reception mode or not.
-
-If '1' ``DTV_ISDBT_LAYERA_*`` values are assigned to the center segment
-and ``DTV_ISDBT_LAYERA_SEGMENT_COUNT`` has to be '1'.
-
-If in addition ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'
-``DTV_ISDBT_PARTIAL_RECEPTION`` represents whether this ISDB-Tsb channel
-is consisting of one segment and layer or three segments and two layers.
-
-Possible values: 0, 1, -1 (AUTO)
-
-
-.. _DTV-ISDBT-SOUND-BROADCASTING:
-
-DTV_ISDBT_SOUND_BROADCASTING
-============================
-
-Used only on ISDB.
-
-This field represents whether the other DTV_ISDBT_*-parameters are
-referring to an ISDB-T and an ISDB-Tsb channel. (See also
-``DTV_ISDBT_PARTIAL_RECEPTION``).
-
-Possible values: 0, 1, -1 (AUTO)
-
-
-.. _DTV-ISDBT-SB-SUBCHANNEL-ID:
-
-DTV_ISDBT_SB_SUBCHANNEL_ID
-==========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-(Note of the author: This might not be the correct description of the
-``SUBCHANNEL-ID`` in all details, but it is my understanding of the
-technical background needed to program a device)
-
-An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
-set of connected ISDB-Tsb channels. In this set of channels every
-channel can be received independently. The number of connected ISDB-Tsb
-segment can vary, e.g. depending on the frequency spectrum bandwidth
-available.
-
-Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
-broadcaster has several possibilities to put those channels in the air:
-Assuming a normal 13-segment ISDB-T spectrum he can align the 8 segments
-from position 1-8 to 5-13 or anything in between.
-
-The underlying layer of segments are subchannels: each segment is
-consisting of several subchannels with a predefined IDs. A sub-channel
-is used to help the demodulator to synchronize on the channel.
-
-An ISDB-T channel is always centered over all sub-channels. As for the
-example above, in ISDB-Tsb it is no longer as simple as that.
-
-``The DTV_ISDBT_SB_SUBCHANNEL_ID`` parameter is used to give the
-sub-channel ID of the segment to be demodulated.
-
-Possible values: 0 .. 41, -1 (AUTO)
-
-
-.. _DTV-ISDBT-SB-SEGMENT-IDX:
-
-DTV_ISDBT_SB_SEGMENT_IDX
-========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-``DTV_ISDBT_SB_SEGMENT_IDX`` gives the index of the segment to be
-demodulated for an ISDB-Tsb channel where several of them are
-transmitted in the connected manner.
-
-Possible values: 0 .. ``DTV_ISDBT_SB_SEGMENT_COUNT`` - 1
-
-Note: This value cannot be determined by an automatic channel search.
-
-
-.. _DTV-ISDBT-SB-SEGMENT-COUNT:
-
-DTV_ISDBT_SB_SEGMENT_COUNT
-==========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-``DTV_ISDBT_SB_SEGMENT_COUNT`` gives the total count of connected
-ISDB-Tsb channels.
-
-Possible values: 1 .. 13
-
-Note: This value cannot be determined by an automatic channel search.
-
-
-.. _isdb-hierq-layers:
-
-DTV-ISDBT-LAYER[A-C] parameters
-===============================
-
-Used only on ISDB.
-
-ISDB-T channels can be coded hierarchically. As opposed to DVB-T in
-ISDB-T hierarchical layers can be decoded simultaneously. For that
-reason a ISDB-T demodulator has 3 Viterbi and 3 Reed-Solomon decoders.
-
-ISDB-T has 3 hierarchical layers which each can use a part of the
-available segments. The total number of segments over all layers has to
-13 in ISDB-T.
-
-There are 3 parameter sets, for Layers A, B and C.
-
-
-.. _DTV-ISDBT-LAYER-ENABLED:
-
-DTV_ISDBT_LAYER_ENABLED
------------------------
-
-Used only on ISDB.
-
-Hierarchical reception in ISDB-T is achieved by enabling or disabling
-layers in the decoding process. Setting all bits of
-``DTV_ISDBT_LAYER_ENABLED`` to '1' forces all layers (if applicable) to
-be demodulated. This is the default.
-
-If the channel is in the partial reception mode
-(``DTV_ISDBT_PARTIAL_RECEPTION`` = 1) the central segment can be decoded
-independently of the other 12 segments. In that mode layer A has to have
-a ``SEGMENT_COUNT`` of 1.
-
-In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb according
-to ``DTV_ISDBT_PARTIAL_RECEPTION``. ``SEGMENT_COUNT`` must be filled
-accordingly.
-
-Only the values of the first 3 bits are used. Other bits will be silently ignored:
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 0: layer A enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 1: layer B enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 2: layer C enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bits 3-31: unused
-
-
-.. _DTV-ISDBT-LAYER-FEC:
-
-DTV_ISDBT_LAYER[A-C]_FEC
-------------------------
-
-Used only on ISDB.
-
-The Forward Error Correction mechanism used by a given ISDB Layer, as
-defined by :c:type:`fe_code_rate`.
-
-
-Possible values are: ``FEC_AUTO``, ``FEC_1_2``, ``FEC_2_3``, ``FEC_3_4``,
-``FEC_5_6``, ``FEC_7_8``
-
-
-.. _DTV-ISDBT-LAYER-MODULATION:
-
-DTV_ISDBT_LAYER[A-C]_MODULATION
--------------------------------
-
-Used only on ISDB.
-
-The modulation used by a given ISDB Layer, as defined by
-:c:type:`fe_modulation`.
-
-Possible values are: ``QAM_AUTO``, ``QPSK``, ``QAM_16``, ``QAM_64``, ``DQPSK``
-
-.. note::
-
-   #. If layer C is ``DQPSK``, then layer B has to be ``DQPSK``.
-
-   #. If layer B is ``DQPSK`` and ``DTV_ISDBT_PARTIAL_RECEPTION``\ = 0,
-      then layer has to be ``DQPSK``.
-
-
-.. _DTV-ISDBT-LAYER-SEGMENT-COUNT:
-
-DTV_ISDBT_LAYER[A-C]_SEGMENT_COUNT
-----------------------------------
-
-Used only on ISDB.
-
-Possible values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, -1 (AUTO)

-=============
-
-Used on DVB-S2, DVB-T2 and ISDB-S.
-
-DVB-S2, DVB-T2 and ISDB-S support the transmission of several streams on
-a single transport stream. This property enables the digital TV driver to
-handle substream filtering, when supported by the hardware. By default,
-substream filtering is disabled.
-
-For DVB-S2 and DVB-T2, the valid substream id range is from 0 to 255.
-
-For ISDB, the valid substream id range is from 1 to 65535.
-
-To disable it, you should use the special macro NO_STREAM_ID_FILTER.

-Obsolete, replaced with DTV_STREAM_ID.
-
-
-.. _DTV-ENUM-DELSYS:
-
-DTV_ENUM_DELSYS
-===============
-
-A Multi standard frontend needs to advertise the delivery systems
-provided. Applications need to enumerate the provided delivery systems,
-before using any other operation with the frontend. Prior to it's
-introduction, FE_GET_INFO was used to determine a frontend type. A
-frontend which provides more than a single delivery system,
-FE_GET_INFO doesn't help much. Applications which intends to use a
-multistandard frontend must enumerate the delivery systems associated
-with it, rather than trying to use FE_GET_INFO. In the case of a
-legacy frontend, the result is just the same as with FE_GET_INFO, but
-in a more structured format
-
-The acceptable values are defined by :c:type:`fe_delivery_system`.
-
-
-.. _DTV-INTERLEAVING:
-

-that parameter. Usually LNA could be found only from terrestrial devices
-if at all.
-
-Possible values: 0, 1, LNA_AUTO
-
-0, LNA off
-
-1, LNA on
-
-use the special macro LNA_AUTO to set LNA auto
-
-
-.. _DTV-SCRAMBLING-SEQUENCE-INDEX:
-
-DTV_SCRAMBLING_SEQUENCE_INDEX
-=============================
-
-Used on DVB-S2.
-
-This 18 bit field, when present, carries the index of the DVB-S2 physical
-layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
-There is no explicit signalling method to convey scrambling sequence index
-to the receiver. If S2 satellite delivery system descriptor is available
-it can be used to read the scrambling sequence index (EN 300 468 table 41).
-
-By default, gold scrambling sequence index 0 is used.
-
-The valid scrambling sequence index range is from 0 to 262142.

-ISDB-T delivery system
-======================
-
-This ISDB-T/ISDB-Tsb API extension should reflect all information needed
-to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
-very sophisticated devices won't need certain parameters to tune.
-
-The information given here should help application writers to know how
-to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.
-
-The details given here about ISDB-T and ISDB-Tsb are just enough to
-basically show the dependencies between the needed parameter values, but
-surely some information is left out. For more detailed information see
-the following documents:
-
-ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
-Broadcasting" and
-
-ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
-Broadcasting".
-
-In order to understand the ISDB specific parameters, one has to have
-some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
-to be known to the reader that an ISDB-T channel consists of 13
-segments, that it can have up to 3 layer sharing those segments, and
-things like that.
-
-The following parameters are valid for ISDB-T:
-
--  :ref:`DTV_API_VERSION <DTV-API-VERSION>`

-
-******************************
-Frontend statistics indicators
-******************************
-
-The values are returned via ``dtv_property.stat``. If the property is
-supported, ``dtv_property.stat.len`` is bigger than zero.
-
-For most delivery systems, ``dtv_property.stat.len`` will be 1 if the
-stats is supported, and the properties will return a single value for
-each parameter.
-
-It should be noted, however, that new OFDM delivery systems like ISDB
-can use different modulation types for each group of carriers. On such
-standards, up to 3 groups of statistics can be provided, and
-``dtv_property.stat.len`` is updated to reflect the "global" metrics,
-plus one metric per each carrier group (called "layer" on ISDB).
-
-So, in order to be consistent with other delivery systems, the first
-value at :c:type:`dtv_property.stat.dtv_stats <dtv_stats>` array refers
-to the global metric. The other elements of the array represent each
-layer, starting from layer A(index 1), layer B (index 2) and so on.
-
-The number of filled elements are stored at ``dtv_property.stat.len``.
-
-Each element of the ``dtv_property.stat.dtv_stats`` array consists on
-two elements:
-
--  ``svalue`` or ``uvalue``, where ``svalue`` is for signed values of
-   the measure (dB measures) and ``uvalue`` is for unsigned values
-   (counters, relative scale)
-
--  ``scale`` - Scale for the value. It can be:
-
-   -  ``FE_SCALE_NOT_AVAILABLE`` - The parameter is supported by the
-      frontend, but it was not possible to collect it (could be a
-      transitory or permanent condition)
-
-   -  ``FE_SCALE_DECIBEL`` - parameter is a signed value, measured in
-      1/1000 dB
-
-   -  ``FE_SCALE_RELATIVE`` - parameter is a unsigned value, where 0
-      means 0% and 65535 means 100%.
-
-   -  ``FE_SCALE_COUNTER`` - parameter is a unsigned value that counts
-      the occurrence of an event, like bit error, block error, or lapsed
-      time.
-
-
-.. _DTV-STAT-SIGNAL-STRENGTH:
-
-DTV_STAT_SIGNAL_STRENGTH
-========================
-
-Indicates the signal strength level at the analog part of the tuner or
-of the demod.
-
-Possible scales for this metric are:
-
--  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
-   measurement was not complete yet.
-
--  ``FE_SCALE_DECIBEL`` - signal strength is in 0.001 dBm units, power
-   measured in miliwatts. This value is generally negative.
-
--  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
-   measurement for power (actually, 0 to 65535).
-
-
-.. _DTV-STAT-CNR:
-
-DTV_STAT_CNR
-============
-
-Indicates the Signal to Noise ratio for the main carrier.
-
-Possible scales for this metric are:
-
--  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
-   measurement was not complete yet.
-
--  ``FE_SCALE_DECIBEL`` - Signal/Noise ratio is in 0.001 dB units.
-
--  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
-   measurement for Signal/Noise (actually, 0 to 65535).
-
-
-.. _DTV-STAT-PRE-ERROR-BIT-COUNT:
-
-DTV_STAT_PRE_ERROR_BIT_COUNT
-============================
-
-Measures the number of bit errors before the forward error correction
-(FEC) on the inner coding block (before Viterbi, LDPC or other inner
-code).
-
-This measure is taken during the same interval as
-``DTV_STAT_PRE_TOTAL_BIT_COUNT``.
-
-In order to get the BER (Bit Error Rate) measurement, it should be
-divided by
-:ref:`DTV_STAT_PRE_TOTAL_BIT_COUNT <DTV-STAT-PRE-TOTAL-BIT-COUNT>`.
-
-This measurement is monotonically increased, as the frontend gets more
-bit count measurements. The frontend may reset it when a
-channel/transponder is tuned.
-
-Possible scales for this metric are:
-
--  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
-   measurement was not complete yet.
-
--  ``FE_SCALE_COUNTER`` - Number of error bits counted before the inner
-   coding.
-

-measurement interval.
-
-This measurement is monotonically increased, as the frontend gets more

-Digital TV Frontend API
-#######################
-
-The Digital TV frontend API was designed to support three groups of delivery
-systems: Terrestrial, cable and Satellite. Currently, the following
-delivery systems are supported:
-
--  Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
-   DTMB, CMMB
-
--  Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B)
-
--  Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
-
-The Digital TV frontend controls several sub-devices including:
-
--  Tuner
-
--  Digital TV demodulator
-
--  Low noise amplifier (LNA)
-
--  Satellite Equipment Control (SEC) [#f1]_.
-
-The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
-Data types and ioctl definitions can be accessed by including
-``linux/dvb/frontend.h`` in your application.
-
-.. note::
-
-   Transmission via the internet (DVB-IP) and MMT (MPEG Media Transport)
-   is not yet handled by this API but a future extension is possible.
-
-.. [#f1]
-
-   On Satellite systems, the API support for the Satellite Equipment
-   Control (SEC) allows to power control and to send/receive signals to
-   control the antenna subsystem, selecting the polarization and choosing
-   the Intermediate Frequency IF) of the Low Noise Block Converter Feed
-   Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
-   (digital SEC) specification is available at
-   `Eutelsat <http://www.eutelsat.com/satellites/4_5_5.html>`__.

-
-``flags``
-    Open flags. Access can either be ``O_RDWR`` or ``O_RDONLY``.
-
-    Multiple opens are allowed with ``O_RDONLY``. In this mode, only

-
-
-Description
-===========
-
-This system call opens a named frontend device
-(``/dev/dvb/adapter?/frontend?``) for subsequent use. Usually the first
-thing to do after a successful open is to find out the frontend type
-with :ref:`FE_GET_INFO`.
-
-The device can be opened in read-only mode, which only allows monitoring
-of device status and statistics, or read/write mode, which allows any
-kind of use (e.g. performing tuning operations.)
-
-In a system with multiple front-ends, it is usually the case that
-multiple devices cannot be open in read/write mode simultaneously. As
-long as a front-end device is opened in read/write mode, other open()
-calls in read/write mode will either fail or block, depending on whether
-non-blocking or blocking mode was specified. A front-end device opened
-in blocking mode can later be put into non-blocking mode (and vice
-versa) using the F_SETFL command of the fcntl system call. This is a
-standard system call, documented in the Linux manual page for fcntl.
-When an open() call has succeeded, the device will be ready for use in
-the specified mode. This implies that the corresponding hardware is
-powered up, and that other front-ends may have been powered down to make
-that possible.
-
-
-Return Value
-============
-
-On success :ref:`open() <frontend_f_open>` returns the new file descriptor.
-On error, -1 is returned, and the ``errno`` variable is set appropriately.
-
-Possible error codes are:
-
-
-On success 0 is returned, and :c:type:`ca_slot_info` is filled.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.

-
-What you need to know
-=====================
-
-The reader of this document is required to have some knowledge in the
-area of digital video broadcasting (Digital TV) and should be familiar with
-part I of the MPEG2 specification ISO/IEC 13818 (aka ITU-T H.222), i.e
-you should know what a program/transport stream (PS/TS) is and what is
-meant by a packetized elementary stream (PES) or an I-frame.
-
-Various Digital TV standards documents are available for download at:
-
-- European standards (DVB): http://www.dvb.org and/or http://www.etsi.org.
-- American standards (ATSC): https://www.atsc.org/standards/
-- Japanese standards (ISDB): http://www.dibeg.org/
-
-It is also necessary to know how to access Linux devices and how to
-use ioctl calls. This also includes the knowledge of C or C++.
-
-
-.. _history:
-
-History
-=======
-
-The first API for Digital TV cards we used at Convergence in late 1999 was an
-extension of the Video4Linux API which was primarily developed for frame
-grabber cards. As such it was not really well suited to be used for Digital
-TV cards and their new features like recording MPEG streams and filtering
-several section and PES data streams at the same time.
-
-In early 2000, Convergence was approached by Nokia with a proposal for a new
-standard Linux Digital TV API. As a commitment to the development of terminals
-based on open standards, Nokia and Convergence made it available to all
-Linux developers and published it on https://linuxtv.org in September
-2000. With the Linux driver for the Siemens/Hauppauge DVB PCI card,
-Convergence provided a first implementation of the Linux Digital TV API.
-Convergence was the maintainer of the Linux Digital TV API in the early
-days.
-
-Now, the API is maintained by the LinuxTV community (i.e. you, the reader
-of this document). The Linux  Digital TV API is constantly reviewed and
-improved together with the improvements at the subsystem's core at the
-Kernel.
-

-
-Overview
-========
-
-
-.. _stb_components:
-
-.. kernel-figure:: dvbstb.svg
-    :alt:   dvbstb.svg
-    :align: center
-
-    Components of a Digital TV card/STB
-
-A Digital TV card or set-top-box (STB) usually consists of the
-following main hardware components:
-
-Frontend consisting of tuner and digital TV demodulator
-   Here the raw signal reaches the digital TV hardware from a satellite dish or
-   antenna or directly from cable. The frontend down-converts and
-   demodulates this signal into an MPEG transport stream (TS). In case
-   of a satellite frontend, this includes a facility for satellite
-   equipment control (SEC), which allows control of LNB polarization,
-   multi feed switches or dish rotors.
-
-Conditional Access (CA) hardware like CI adapters and smartcard slots
-   The complete TS is passed through the CA hardware. Programs to which
-   the user has access (controlled by the smart card) are decoded in
-   real time and re-inserted into the TS.
-
-   .. note::
-
-      Not every digital TV hardware provides conditional access hardware.
-
-Demultiplexer which filters the incoming Digital TV MPEG-TS stream
-   The demultiplexer splits the TS into its components like audio and
-   video streams. Besides usually several of such audio and video
-   streams it also contains data streams with information about the
-   programs offered in this or other streams of the same provider.
-
-Audio and video decoder
-   The main targets of the demultiplexer are audio and video
-   decoders. After decoding, they pass on the uncompressed audio and
-   video to the computer screen or to a TV set.
-
-   .. note::
-
-      Modern hardware usually doesn't have a separate decoder hardware, as
-      such functionality can be provided by the main CPU, by the graphics
-      adapter of the system or by a signal processing hardware embedded on
-      a Systems on a Chip (SoC) integrated circuit.
-
-      It may also not be needed for certain usages (e.g. for data-only
-      uses like “internet over satellite”).
-
-:ref:`stb_components` shows a crude schematic of the control and data
-flow between those components.
-
-
-
-.. _dvb_devices:
-
-Linux Digital TV Devices
-========================
-
-The Linux Digital TV API lets you control these hardware components through
-currently six Unix-style character devices for video, audio, frontend,
-demux, CA and IP-over-DVB networking. The video and audio devices
-control the MPEG2 decoder hardware, the frontend device the tuner and
-the Digital TV demodulator. The demux device gives you control over the PES
-and section filters of the hardware. If the hardware does not support
-filtering these filters can be implemented in software. Finally, the CA
-device controls all the conditional access capabilities of the hardware.
-It can depend on the individual security requirements of the platform,
-if and how many of the CA functions are made available to the
-application through this device.
-
-All devices can be found in the ``/dev`` tree under ``/dev/dvb``. The
-individual devices are called:
-
--  ``/dev/dvb/adapterN/audioM``,
-
--  ``/dev/dvb/adapterN/videoM``,
-
--  ``/dev/dvb/adapterN/frontendM``,
-
--  ``/dev/dvb/adapterN/netM``,
-
--  ``/dev/dvb/adapterN/demuxM``,
-
--  ``/dev/dvb/adapterN/dvrM``,
-
--  ``/dev/dvb/adapterN/caM``,
-
-where ``N`` enumerates the Digital TV cards in a system starting from 0, and
-``M`` enumerates the devices of each type within each adapter, starting
-from 0, too. We will omit the “``/dev/dvb/adapterN/``\ ” in the further
-discussion of these devices.
-
-More details about the data structures and function calls of all the
-devices are described in the following chapters.
-
-
-.. _include_files:
-
-API include files
-=================
-
-For each of the Digital TV devices a corresponding include file exists. The
-Digital TV API include files should be included in application sources with a
-partial path like:
-
-
-.. code-block:: c
-
-	#include <linux/dvb/ca.h>
-
-	#include <linux/dvb/dmx.h>
-
-	#include <linux/dvb/frontend.h>
-
-	#include <linux/dvb/net.h>
-
-
-To enable applications to support different API version, an additional
-include file ``linux/dvb/version.h`` exists, which defines the constant
-``DVB_API_VERSION``. This document describes ``DVB_API_VERSION 5.10``.

-Digital TV Network API
-######################
-
-The Digital TV net device controls the mapping of data packages that are part
-of a transport stream to be mapped into a virtual network interface,
-visible through the standard Linux network protocol stack.
-
-Currently, two encapsulations are supported:
-
--  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
-
--  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
-
-In order to create the Linux virtual network interfaces, an application
-needs to tell to the Kernel what are the PIDs and the encapsulation
-types that are present on the transport stream. This is done through
-``/dev/dvb/adapter?/net?`` device node. The data will be available via
-virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
-the standard ip tools (like ip, route, netstat, ifconfig, etc).
-
-Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
-header.

-When an open() call has succeeded, the device will be ready for use. The
-significance of blocking or non-blocking mode is described in the

-affect the semantics of the open() call itself. A device opened in
-blocking mode can later be put into non-blocking mode (and vice versa)
-using the F_SETFL command of the fcntl system call. This is a standard
-system call, documented in the Linux manual page for fcntl. Only one
-user can open the Video Device in O_RDWR mode. All other attempts to
-open the device in this mode will fail, and an error-code will be
-returned. If the Video Device is opened in O_RDONLY mode, the only
-ioctl call that can be used is VIDEO_GET_STATUS. All other call will
-return an error code.

-
-This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
-use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
-
-This ioctl call returns an event of type video_event if available. If
-an event is not available, the behavior depends on whether the device is
-in blocking or non-blocking mode. In the latter case, the call fails
-immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
-blocks until an event becomes available. The standard Linux poll()
-and/or select() system calls can be used with the device file descriptor
-to watch for new events. For select(), the file descriptor should be
-included in the exceptfds argument, and for poll(), POLLPRI should be
-specified as the wake-up condition. Read-only permissions are sufficient
-for this ioctl call.

-#######################
-Digital TV Video Device
-#######################
-
-The Digital TV video device controls the MPEG2 video decoder of the Digital
-TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
-types and and ioctl definitions can be accessed by including
-**linux/dvb/video.h** in your application.
-
-Note that the Digital TV video device only controls decoding of the MPEG video
-stream, not its presentation on the TV or computer screen. On PCs this
-is typically handled by an associated video4linux device, e.g.
-**/dev/video**, which allows scaling and defining output windows.
-
-Some Digital TV cards don’t have their own MPEG decoder, which results in the
-omission of the audio and video device as well as the video4linux
-device.
-
-The ioctls that deal with SPUs (sub picture units) and navigation
-packets are only supported on some MPEG decoders made for DVD playback.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-****************
-Video Data Types
-****************
-
-
-.. _video-format-t:
-
-video_format_t
-==============
-
-The ``video_format_t`` data type defined by
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_FORMAT_4_3,     /* Select 4:3 format */
-	VIDEO_FORMAT_16_9,    /* Select 16:9 format. */
-	VIDEO_FORMAT_221_1    /* 2.21:1 */
-    } video_format_t;
-
-is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
-aspect ratio the output hardware (e.g. TV) has. It is also used in the
-data structures video_status (??) returned by VIDEO_GET_STATUS (??)
-and video_event (??) returned by VIDEO_GET_EVENT (??) which report
-about the display format of the current video stream.
-
-
-.. _video-displayformat-t:
-
-video_displayformat_t
-=====================
-
-In case the display format of the video stream and of the display
-hardware differ the application has to specify how to handle the
-cropping of the picture. This can be done using the
-VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_PAN_SCAN,       /* use pan and scan format */
-	VIDEO_LETTER_BOX,     /* use letterbox format */
-	VIDEO_CENTER_CUT_OUT  /* use center cut out format */
-    } video_displayformat_t;
-
-as argument.
-
-
-.. _video-stream-source-t:
-
-video_stream_source_t
-=====================
-
-The video stream source is set through the VIDEO_SELECT_SOURCE call
-and can take the following values, depending on whether we are replaying
-from an internal (demuxer) or external (user write) source.
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
-	VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
-		       comes from the user through the write
-		       system call */
-    } video_stream_source_t;
-
-VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-VIDEO_SOURCE_MEMORY is selected the stream comes from the application
-through the **write()** system call.
-
-
-.. _video-play-state-t:
-
-video_play_state_t
-==================
-
-The following values can be returned by the VIDEO_GET_STATUS call
-representing the state of video playback.
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_STOPPED, /* Video is stopped */
-	VIDEO_PLAYING, /* Video is currently playing */
-	VIDEO_FREEZED  /* Video is freezed */
-    } video_play_state_t;
-
-
-.. c:type:: video_command
-
-struct video_command
-====================
-
-The structure must be zeroed before use by the application This ensures
-it can be extended safely in the future.
-
-
-.. code-block:: c
-
-    struct video_command {
-	__u32 cmd;
-	__u32 flags;
-	union {
-	    struct {

-
-struct video_event
-==================
-
-The following is the structure of a video event as it is returned by the
-VIDEO_GET_EVENT call.
-
-
-.. code-block:: c
-
-    struct video_event {
-	__s32 type;
-    #define VIDEO_EVENT_SIZE_CHANGED    1
-    #define VIDEO_EVENT_FRAME_RATE_CHANGED  2
-    #define VIDEO_EVENT_DECODER_STOPPED     3
-    #define VIDEO_EVENT_VSYNC       4
-	long timestamp;
-	union {
-	    video_size_t size;
-	    unsigned int frame_rate;    /* in frames per 1000sec */
-	    unsigned char vsync_field;  /* unknown/odd/even/progressive */
-	} u;
-    };
-
-
-.. c:type:: video_status
-
-struct video_status
-===================
-
-The VIDEO_GET_STATUS call returns the following structure informing
-about various states of the playback operation.
-
-
-.. code-block:: c
-
-    struct video_status {
-	int                   video_blank;   /* blank video on freeze? */
-	video_play_state_t    play_state;    /* current state of playback */
-	video_stream_source_t stream_source; /* current source (demux/memory) */
-	video_format_t        video_format;  /* current aspect ratio of stream */
-	video_displayformat_t display_format;/* selected cropping mode */
-    };
-
-If video_blank is set video will be blanked out if the channel is
-changed or if playback is stopped. Otherwise, the last picture will be
-displayed. play_state indicates if the video is currently frozen,
-stopped, or being played back. The stream_source corresponds to the
-selected source for the video stream. It can come either from the
-demultiplexer or from memory. The video_format indicates the aspect
-ratio (one of 4:3 or 16:9) of the currently played video stream.
-Finally, display_format corresponds to the selected cropping mode in
-case the source video format is not the same as the format of the output
-device.
-
-
-.. c:type:: video_still_picture
-
-struct video_still_picture
-==========================
-
-An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
-within the following structure.
-
-
-.. code-block:: c
-
-    /* pointer to and size of a single iframe in memory */
-    struct video_still_picture {
-	char *iFrame;        /* pointer to a single iframe in memory */
-	int32_t size;
-    };
-
-
-.. _video_caps:
-
-video capabilities
-==================
-
-A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
-following bits set according to the hardwares capabilities.
-
-
-.. code-block:: c
-
-     /* bit definitions for capabilities: */
-     /* can the hardware decode MPEG1 and/or MPEG2? */
-     #define VIDEO_CAP_MPEG1   1
-     #define VIDEO_CAP_MPEG2   2

-Document's overall subject (or to related matters) and contains nothing
-that could fall directly within that overall subject. (For example, if
-the Document is in part a textbook of mathematics, a Secondary Section
-may not explain any mathematics.) The relationship could be a matter of
-historical connection with the subject or with related matters, or of
-legal, commercial, philosophical, ethical or political position
-regarding them.
-
-
-.. _fdl-invariant:
-
-The “Invariant Sections” are certain
-:ref:`Secondary Sections <fdl-secondary>` whose titles are designated,
-as being those of Invariant Sections, in the notice that says that the
-:ref:`Document <fdl-document>` is released under this License.
-
-
-.. _fdl-cover-texts:
-
-The “Cover Texts” are certain short passages of text that are listed, as
-Front-Cover Texts or Back-Cover Texts, in the notice that says that the
-:ref:`Document <fdl-document>` is released under this License.
-
-
-.. _fdl-transparent:
-
-A “Transparent” copy of the :ref:`Document <fdl-document>` means a
-machine-readable copy, represented in a format whose specification is
-available to the general public, whose contents can be viewed and edited
-directly and straightforwardly with generic text editors or (for images
-composed of pixels) generic paint programs or (for drawings) some widely
-available drawing editor, and that is suitable for input to text
-formatters or for automatic translation to a variety of formats suitable
-for input to text formatters. A copy made in an otherwise Transparent
-file format whose markup has been designed to thwart or discourage
-subsequent modification by readers is not Transparent. A copy that is
-not “Transparent” is called “Opaque”.
-
-Examples of suitable formats for Transparent copies include plain ASCII
-without markup, Texinfo input format, LaTeX input format, SGML or XML
-using a publicly available DTD, and standard-conforming simple HTML
-designed for human modification. Opaque formats include PostScript, PDF,
-proprietary formats that can be read and edited only by proprietary word
-processors, SGML or XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML produced by some
-word processors for output purposes only.
-
-
-.. _fdl-title-page:
-
-The “Title Page” means, for a printed book, the title page itself, plus
-such following pages as are needed to hold, legibly, the material this
-License requires to appear in the title page. For works in formats which
-do not have any title page as such, “Title Page” means the text near the
-most prominent appearance of the work's title, preceding the beginning
-of the body of the text.
-
-

-
-2. VERBATIM COPYING
-===================
-
-You may copy and distribute the :ref:`Document <fdl-document>` in any
-medium, either commercially or noncommercially, provided that this
-License, the copyright notices, and the license notice saying this
-License applies to the Document are reproduced in all copies, and that
-you add no other conditions whatsoever to those of this License. You may
-not use technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in
-:ref:`section 3 <fdl-section3>`.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-
-.. _fdl-section3:
-
-3. COPYING IN QUANTITY
-======================
-
-If you publish printed copies of the :ref:`Document <fdl-document>`
-numbering more than 100, and the Document's license notice requires
-:ref:`Cover Texts <fdl-cover-texts>`, you must enclose the copies in
-covers that carry, clearly and legibly, all these Cover Texts:
-Front-Cover Texts on the front cover, and Back-Cover Texts on the back
-cover. Both covers must also clearly and legibly identify you as the
-publisher of these copies. The front cover must present the full title
-with all words of the title equally prominent and visible. You may add
-other material on the covers in addition. Copying with changes limited
-to the covers, as long as they preserve the title of the
-:ref:`Document <fdl-document>` and satisfy these conditions, can be
-treated as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute :ref:`Opaque <fdl-transparent>` copies of
-the :ref:`Document <fdl-document>` numbering more than 100, you must
-either include a machine-readable :ref:`Transparent <fdl-transparent>`
-copy along with each Opaque copy, or state in or with each Opaque copy a
-publicly-accessible computer-network location containing a complete
-Transparent copy of the Document, free of added material, which the
-general network-using public has access to download anonymously at no
-charge using public-standard network protocols. If you use the latter
-option, you must take reasonably prudent steps, when you begin
-distribution of Opaque copies in quantity, to ensure that this
-Transparent copy will remain thus accessible at the stated location
-until at least one year after the last time you distribute an Opaque
-copy (directly or through your agents or retailers) of that edition to
-the public.
-
-It is requested, but not required, that you contact the authors of the
-:ref:`Document <fdl-document>` well before redistributing any large
-number of copies, to give them a chance to provide you with an updated
-version of the Document.
-
-
-.. _fdl-section4:
-
-4. MODIFICATIONS
-================
-
-You may copy and distribute a :ref:`Modified Version <fdl-modified>`
-of the :ref:`Document <fdl-document>` under the conditions of sections
-:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` above, provided
-that you release the Modified Version under precisely this License, with
-the Modified Version filling the role of the Document, thus licensing
-distribution and modification of the Modified Version to whoever
-possesses a copy of it. In addition, you must do these things in the
-Modified Version:
-
--  **A.**
-   Use in the :ref:`Title Page <fdl-title-page>` (and on the covers,
-   if any) a title distinct from that of the
-   :ref:`Document <fdl-document>`, and from those of previous versions
-   (which should, if there were any, be listed in the History section of
-   the Document). You may use the same title as a previous version if
-   the original publisher of that version gives permission.
-
--  **B.**
-   List on the :ref:`Title Page <fdl-title-page>`, as authors, one or
-   more persons or entities responsible for authorship of the
-   modifications in the :ref:`Modified Version <fdl-modified>`,
-   together with at least five of the principal authors of the
-   :ref:`Document <fdl-document>` (all of its principal authors, if it
-   has less than five).
-
--  **C.**
-   State on the :ref:`Title Page <fdl-title-page>` the name of the
-   publisher of the :ref:`Modified Version <fdl-modified>`, as the
-   publisher.
-
--  **D.**
-   Preserve all the copyright notices of the
-   :ref:`Document <fdl-document>`.
-
--  **E.**
-   Add an appropriate copyright notice for your modifications adjacent
-   to the other copyright notices.
-
--  **F.**
-   Include, immediately after the copyright notices, a license notice
-   giving the public permission to use the
-   :ref:`Modified Version <fdl-modified>` under the terms of this
-   License, in the form shown in the Addendum below.
-
--  **G.**
-   Preserve in that license notice the full lists of
-   :ref:`Invariant Sections <fdl-invariant>` and required
-   :ref:`Cover Texts <fdl-cover-texts>` given in the
-   :ref:`Document's <fdl-document>` license notice.
-
--  **H.**
-   Include an unaltered copy of this License.
-
--  **I.**
-   Preserve the section entitled “History”, and its title, and add to it
-   an item stating at least the title, year, new authors, and publisher
-   of the :ref:`Modified Version <fdl-modified>` as given on the
-   :ref:`Title Page <fdl-title-page>`. If there is no section entitled
-   “History” in the :ref:`Document <fdl-document>`, create one stating
-   the title, year, authors, and publisher of the Document as given on
-   its Title Page, then add an item describing the Modified Version as
-   stated in the previous sentence.
-
--  **J.**
-   Preserve the network location, if any, given in the
-   :ref:`Document <fdl-document>` for public access to a
-   :ref:`Transparent <fdl-transparent>` copy of the Document, and
-   likewise the network locations given in the Document for previous
-   versions it was based on. These may be placed in the “History”
-   section. You may omit a network location for a work that was
-   published at least four years before the Document itself, or if the
-   original publisher of the version it refers to gives permission.
-
--  **K.**
-   In any section entitled “Acknowledgements” or “Dedications”, preserve
-   the section's title, and preserve in the section all the substance
-   and tone of each of the contributor acknowledgements and/or
-   dedications given therein.
-
--  **L.**
-   Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the
-   :ref:`Document <fdl-document>`, unaltered in their text and in
-   their titles. Section numbers or the equivalent are not considered
-   part of the section titles.
-
--  **M.**
-   Delete any section entitled “Endorsements”. Such a section may not be
-   included in the :ref:`Modified Version <fdl-modified>`.
-
--  **N.**
-   Do not retitle any existing section as “Endorsements” or to conflict
-   in title with any :ref:`Invariant Section <fdl-invariant>`.
-
-If the :ref:`Modified Version <fdl-modified>` includes new
-front-matter sections or appendices that qualify as
-:ref:`Secondary Sections <fdl-secondary>` and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the list
-of :ref:`Invariant Sections <fdl-invariant>` in the Modified Version's
-license notice. These titles must be distinct from any other section
-titles.
-
-You may add a section entitled “Endorsements”, provided it contains
-nothing but endorsements of your
-:ref:`Modified Version <fdl-modified>` by various parties--for
-example, statements of peer review or that the text has been approved by
-an organization as the authoritative definition of a standard.
-
-You may add a passage of up to five words as a
-:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25
-words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the
-list of :ref:`Cover Texts <fdl-cover-texts>` in the
-:ref:`Modified Version <fdl-modified>`. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or through
-arrangements made by) any one entity. If the
-:ref:`Document <fdl-document>` already includes a cover text for the
-same cover, previously added by you or by arrangement made by the same
-entity you are acting on behalf of, you may not add another; but you may
-replace the old one, on explicit permission from the previous publisher
-that added the old one.
-
-The author(s) and publisher(s) of the :ref:`Document <fdl-document>`
-do not by this License give permission to use their names for publicity
-for or to assert or imply endorsement of any
-:ref:`Modified Version <fdl-modified>`.
-
-
-.. _fdl-section5:
-
-5. COMBINING DOCUMENTS
-======================
-
-You may combine the :ref:`Document <fdl-document>` with other
-documents released under this License, under the terms defined in
-:ref:`section 4 <fdl-section4>` above for modified versions, provided
-that you include in the combination all of the
-:ref:`Invariant Sections <fdl-invariant>` of all of the original
-documents, unmodified, and list them all as Invariant Sections of your
-combined work in its license notice.
-
-The combined work need only contain one copy of this License, and
-multiple identical :ref:`Invariant Sections <fdl-invariant>` may be
-replaced with a single copy. If there are multiple Invariant Sections
-with the same name but different contents, make the title of each such
-section unique by adding at the end of it, in parentheses, the name of
-the original author or publisher of that section if known, or else a
-unique number. Make the same adjustment to the section titles in the
-list of Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections entitled “History” in
-the various original documents, forming one section entitled “History”;
-likewise combine any sections entitled “Acknowledgements”, and any
-sections entitled “Dedications”. You must delete all sections entitled
-“Endorsements.”
-
-
-.. _fdl-section6:
-
-6. COLLECTIONS OF DOCUMENTS
-===========================
-
-You may make a collection consisting of the
-:ref:`Document <fdl-document>` and other documents released under this
-License, and replace the individual copies of this License in the
-various documents with a single copy that is included in the collection,
-provided that you follow the rules of this License for verbatim copying
-of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-
-.. _fdl-section7:
-
-7. AGGREGATION WITH INDEPENDENT WORKS
-=====================================
-
-A compilation of the :ref:`Document <fdl-document>` or its derivatives
-with other separate and independent documents or works, in or on a
-volume of a storage or distribution medium, does not as a whole count as
-a :ref:`Modified Version <fdl-modified>` of the Document, provided no
-compilation copyright is claimed for the compilation. Such a compilation
-is called an “aggregate”, and this License does not apply to the other
-self-contained works thus compiled with the Document , on account of
-their being thus compiled, if they are not themselves derivative works
-of the Document. If the :ref:`Cover Text <fdl-cover-texts>`
-requirement of :ref:`section 3 <fdl-section3>` is applicable to these
-copies of the Document, then if the Document is less than one quarter of
-the entire aggregate, the Document's Cover Texts may be placed on covers
-that surround only the Document within the aggregate. Otherwise they
-must appear on covers around the whole aggregate.
-
-
-.. _fdl-section8:
-
-8. TRANSLATION
-==============
-
-Translation is considered a kind of modification, so you may distribute
-translations of the :ref:`Document <fdl-document>` under the terms of
-:ref:`section 4 <fdl-section4>`. Replacing
-:ref:`Invariant Sections <fdl-invariant>` with translations requires
-special permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License provided that you also include the original
-English version of this License. In case of a disagreement between the
-translation and the original English version of this License, the
-original English version will prevail.
-
-
-.. _fdl-section9:
-
-9. TERMINATION
-==============
-
-You may not copy, modify, sublicense, or distribute the
-:ref:`Document <fdl-document>` except as expressly provided for under
-this License. Any other attempt to copy, modify, sublicense or
-distribute the Document is void, and will automatically terminate your
-rights under this License. However, parties who have received copies, or
-rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-
-.. _fdl-section10:
-
-10. FUTURE REVISIONS OF THIS LICENSE
-====================================
-
-The `Free Software Foundation <http://www.gnu.org/fsf/fsf.html>`__
-may publish new, revised versions of the GNU Free Documentation License
-from time to time. Such new versions will be similar in spirit to the
-present version, but may differ in detail to address new problems or
-concerns. See
-`http://www.gnu.org/copyleft/ <http://www.gnu.org/copyleft>`__.
-
-Each version of the License is given a distinguishing version number. If
-the :ref:`Document <fdl-document>` specifies that a particular
-numbered version of this License “or any later version” applies to it,
-you have the option of following the terms and conditions either of that
-specified version or of any later version that has been published (not
-as a draft) by the Free Software Foundation. If the Document does not
-specify a version number of this License, you may choose any version
-ever published (not as a draft) by the Free Software Foundation.

-    -  -  ``EAGAIN`` (aka ``EWOULDBLOCK``)
-
-       -  The ioctl can't be handled because the device is in state where it
-	  can't perform it. This could happen for example in case where
-	  device is sleeping and ioctl is performed to query statistics. It
-	  is also returned when the ioctl would need to wait for an event,
-	  but the device was opened in non-blocking mode.
-
-    -  -  ``EBADF``
-
-       -  The file descriptor is not a valid.
-
-    -  -  ``EBUSY``
-
-       -  The ioctl can't be handled because the device is busy. This is
-	  typically return while device is streaming, and an ioctl tried to
-	  change something that would affect the stream, or would require
-	  the usage of a hardware resource that was already allocated. The

-    -  -  ``EFAULT``
-
-       -  There was a failure while copying data from/to userspace, probably

-
-    -  -  ``EINVAL``
-
-       -  One or more of the ioctl parameters are invalid or out of the

-
-       -  There's not enough memory to handle the desired operation.
-
-    -  -  ``ENOTTY``
-
-       -  The ioctl is not supported by the driver, actually meaning that

-
-    -  -  ``ENOSPC``
-
-       -  On USB devices, the stream ioctl's can return this error, meaning

-Introduction
-============
-
-Media devices increasingly handle multiple related functions. Many USB
-cameras include microphones, video capture hardware can also output
-video, or SoC camera interfaces also perform memory-to-memory operations
-similar to video codecs.
-
-Independent functions, even when implemented in the same hardware, can
-be modelled as separate devices. A USB camera with a microphone will be
-presented to userspace applications as V4L2 and ALSA capture devices.
-The devices' relationships (when using a webcam, end-users shouldn't
-have to manually select the associated USB microphone), while not made
-available directly to applications by the drivers, can usually be
-retrieved from sysfs.
-
-With more and more advanced SoC devices being introduced, the current
-approach will not scale. Device topologies are getting increasingly
-complex and can't always be represented by a tree structure. Hardware
-blocks are shared between different functions, creating dependencies
-between seemingly unrelated devices.
-
-Kernel abstraction APIs such as V4L2 and ALSA provide means for
-applications to access hardware parameters. As newer hardware expose an
-increasingly high number of those parameters, drivers need to guess what
-applications really require based on limited information, thereby
-implementing policies that belong to userspace.
-
-The media controller API aims at solving those problems.

-Media device model
-==================
-
-Discovering a device internal topology, and configuring it at runtime,
-is one of the goals of the media controller API. To achieve this,
-hardware devices and Linux Kernel interfaces are modelled as graph
-objects on an oriented graph. The object types that constitute the graph
-are:
-
--  An **entity** is a basic media hardware or software building block.
-   It can correspond to a large variety of logical blocks such as
-   physical hardware devices (CMOS sensor for instance), logical
-   hardware devices (a building block in a System-on-Chip image
-   processing pipeline), DMA channels or physical connectors.
-
--  An **interface** is a graph representation of a Linux Kernel
-   userspace API interface, like a device node or a sysfs file that
-   controls one or more entities in the graph.
-
--  A **pad** is a data connection endpoint through which an entity can
-   interact with other entities. Data (not restricted to video) produced
-   by an entity flows from the entity's output to one or more entity
-   inputs. Pads should not be confused with physical pins at chip
-   boundaries.
-
--  A **data link** is a point-to-point oriented connection between two
-   pads, either on the same entity or on different entities. Data flows
-   from a source pad to a sink pad.
-
--  An **interface link** is a point-to-point bidirectional control
-   connection between a Linux Kernel interface and an entity.

-
-    #include <sys/ioctl.h>
-
-
-.. c:function:: int ioctl( int fd, int request, void *argp )
-    :name: mc-ioctl
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <mc-open>`.
-
-``request``
-    Media ioctl request code as defined in the media.h header file, for
-    example MEDIA_IOC_SETUP_LINK.
-
-``argp``
-    Pointer to a request-specific structure.
-
-
-Description
-===========
-
-The :ref:`ioctl() <media-func-ioctl>` function manipulates media device
-parameters. The argument ``fd`` must be an open file descriptor.
-
-The ioctl ``request`` code specifies the media function to be called. It
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes.
-
-Macros and structures definitions specifying media ioctl requests and
-their parameters are located in the media.h header file. All media ioctl
-requests, their respective function and parameters are specified in
-:ref:`media-user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-Request-specific error codes are listed in the individual requests
-descriptions.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-EACCES
-    The requested access to the file is not allowed.
-
-EMFILE
-    The process already has the maximum number of files open.
-
-ENFILE
-    The system limit on the total number of open files has been reached.
-
-ENOMEM
-    Insufficient kernel memory was available.
-

-
-
-Description
-===========
-
-All media devices must support the ``MEDIA_IOC_DEVICE_INFO`` ioctl. To
-query device information, applications call the ioctl with a pointer to
-a struct :c:type:`media_device_info`. The driver
-fills the structure and returns the information to the application. The
-ioctl never fails.

-    *  -  char
-       -  ``driver``\ [16]
-       -  Name of the driver implementing the media API as a NUL-terminated
-	  ASCII string. The driver version is stored in the
-	  ``driver_version`` field.
-
-	  Driver specific applications can use this information to verify
-	  the driver identity. It is also useful to work around known bugs,
-	  or to identify drivers in error reports.
-
-    *  -  char
-       -  ``model``\ [32]
-       -  Device model name as a NUL-terminated UTF-8 string. The device
-	  version is stored in the ``device_version`` field and is not be
-	  appended to the model name.
-
-    *  -  char
-       -  ``serial``\ [40]
-       -  Serial number as a NUL-terminated ASCII string.
-
-    *  -  char
-       -  ``bus_info``\ [32]
-       -  Location of the device in the system as a NUL-terminated ASCII
-	  string. This includes the bus type name (PCI, USB, ...) and a
-	  bus-specific identifier.
-
-    *  -  __u32
-       -  ``media_version``
-       -  Media API version, formatted with the ``KERNEL_VERSION()`` macro.

-       -  Hardware device revision in a driver-specific format.
-
-    *  -  __u32
-       -  ``driver_version``
-       -  Media device driver version, formatted with the
-	  ``KERNEL_VERSION()`` macro. Together with the ``driver`` field
-	  this identifies a particular driver.
-
-    *  -  __u32
-       -  ``reserved``\ [31]
-       -  Reserved for future extensions. Drivers and applications must set
-	  this array to zero.
-
-
-The ``serial`` and ``bus_info`` fields can be used to distinguish
-between multiple instances of otherwise identical hardware. The serial
-number takes precedence when provided and can be assumed to be unique.
-If the serial number is an empty string, the ``bus_info`` field can be
-used instead. The ``bus_info`` field is guaranteed to be unique, but can
-vary across reboots or device unplug/replug.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-===========
-
-To query the attributes of an entity, applications set the id field of a

-
-To enumerate pads and/or links for a given entity, applications set the

-MEDIA_IOC_ENUM_LINKS ioctl with a pointer to this structure.
-
-If the ``pads`` field is not NULL, the driver fills the ``pads`` array
-with information about the entity's pads. The array must have enough
-room to store all the entity's pads. The number of pads can be retrieved
-with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
-
-If the ``links`` field is not NULL, the driver fills the ``links`` array
-with information about the entity's outbound links. The array must have

-outbound links can be retrieved with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
-
-Only forward links that originate at one of the entity's source pads are
-returned during the enumeration process.

-
-Description
-===========
-
-The typical usage of this ioctl is to call it twice. On the first call,
-the structure defined at struct
-:c:type:`media_v2_topology` should be zeroed. At
-return, if no errors happen, this ioctl will return the
-``topology_version`` and the total number of entities, interfaces, pads
-and links.
-
-Before the second call, the userspace should allocate arrays to store
-the graph elements that are desired, putting the pointers to them at the
-ptr_entities, ptr_interfaces, ptr_links and/or ptr_pads, keeping the
-other values untouched.
-
-If the ``topology_version`` remains the same, the ioctl should fill the
-desired arrays with the media graph elements.

-
-``argp``
-    Pointer to an integer.
-
-
-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this ioctl can be used to allocate a request. If it is not supported, then
-``errno`` is set to ``ENOTTY``. A request is accessed through a file descriptor
-that is returned in ``*argp``.
-
-If the request was successfully allocated, then the request file descriptor
-can be passed to the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctls.
-
-In addition, the request can be queued by calling
-:ref:`MEDIA_REQUEST_IOC_QUEUE` and re-initialized by calling
-:ref:`MEDIA_REQUEST_IOC_REINIT`.
-
-Finally, the file descriptor can be :ref:`polled <request-func-poll>` to wait
-for the request to complete.
-
-The request will remain allocated until all the file descriptors associated
-with it are closed by :ref:`close() <request-func-close>` and the driver no
-longer uses the request internally. See also

-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-
-
-Description
-===========
-
-To change link properties applications fill a struct

-information (source and sink pad) and the new requested link flags. They
-then call the MEDIA_IOC_SETUP_LINK ioctl with a pointer to that

-
-The only configurable property is the ``ENABLED`` link flag to
-enable/disable a link. Links marked with the ``IMMUTABLE`` link flag can

-
-Link configuration has no side effect on other links. If an enabled link
-at the sink pad prevents the link from being enabled, the driver returns
-with an ``EBUSY`` error code.
-
-Only links marked with the ``DYNAMIC`` link flag can be enabled/disabled
-while streaming media data. Attempting to enable or disable a streaming
-non-dynamic link will return an ``EBUSY`` error code.

-    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
-
-
-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this request ioctl can be used to queue a previously allocated request.
-
-If the request was successfully queued, then the file descriptor can be
-:ref:`polled <request-func-poll>` to wait for the request to complete.
-
-If the request was already queued before, then ``EBUSY`` is returned.
-Other errors can be returned if the contents of the request contained
-invalid or inconsistent data, see the next section for a list of
-common error codes. On error both the request and driver state are unchanged.
-
-Once a request is queued, then the driver is required to gracefully handle
-errors that occur when the request is applied to the hardware. The
-exception is the ``EIO`` error which signals a fatal error that requires
-the application to stop streaming to reset the hardware state.
-
-It is not allowed to mix queuing requests with queuing buffers directly
-(without a request). ``EBUSY`` will be returned if the first buffer was
-queued directly and you next try to queue a request, or vice versa.
-
-A request must contain at least one buffer, otherwise this ioctl will
-return an ``ENOENT`` error.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EBUSY
-    The request was already queued or the application queued the first
-    buffer directly, but later attempted to use a request. It is not permitted
-    to mix the two APIs.
-ENOENT
-    The request did not contain any buffers. All requests are required
-    to have at least one buffer. This can also be returned if some required
-    configuration is missing in the request.
-ENOMEM
-    Out of memory when allocating internal data structures for this
-    request.
-EINVAL
-    The request has invalid data.
-EIO
-    The hardware is in a bad state. To recover, the application needs to

-MEDIA_REQUEST_IOC_REINIT - Re-initialize a request
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int request_fd, MEDIA_REQUEST_IOC_REINIT )
-    :name: MEDIA_REQUEST_IOC_REINIT
-
-
-Arguments
-=========
-
-``request_fd``
-    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
-
-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this request ioctl can be used to re-initialize a previously allocated
-request.
-
-Re-initializing a request will clear any existing data from the request.
-This avoids having to :ref:`close() <request-func-close>` a completed
-request and allocate a new request. Instead the completed request can just
-be re-initialized and it is ready to be used again.
-
-A request can only be re-initialized if it either has not been queued
-yet, or if it was queued and completed. Otherwise it will set ``errno``
-to ``EBUSY``. No other error codes can be returned.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately.
-
-EBUSY
-    The request is queued but not yet completed.

-Request API
-===========
-
-The Request API has been designed to allow V4L2 to deal with requirements of
-modern devices (stateless codecs, complex camera pipelines, ...) and APIs
-(Android Codec v2). One such requirement is the ability for devices belonging to
-the same pipeline to reconfigure and collaborate closely on a per-frame basis.
-Another is support of stateless codecs, which require controls to be applied
-to specific frames (aka 'per-frame controls') in order to be used efficiently.
-
-While the initial use-case was V4L2, it can be extended to other subsystems
-as well, as long as they use the media controller.
-
-Supporting these features without the Request API is not always possible and if
-it is, it is terribly inefficient: user-space would have to flush all activity
-on the media pipeline, reconfigure it for the next frame, queue the buffers to
-be processed with that configuration, and wait until they are all available for
-dequeuing before considering the next frame. This defeats the purpose of having
-buffer queues since in practice only one buffer would be queued at a time.
-
-The Request API allows a specific configuration of the pipeline (media
-controller topology + configuration for each media entity) to be associated with
-specific buffers. This allows user-space to schedule several tasks ("requests")
-with different configurations in advance, knowing that the configuration will be
-applied when needed to get the expected result. Configuration values at the time
-of request completion are also available for reading.
-
-General Usage
--------------
-
-The Request API extends the Media Controller API and cooperates with
-subsystem-specific APIs to support request usage. At the Media Controller
-level, requests are allocated from the supporting Media Controller device
-node. Their life cycle is then managed through the request file descriptors in
-an opaque way. Configuration data, buffer handles and processing results
-stored in requests are accessed through subsystem-specific APIs extended for
-request support, such as V4L2 APIs that take an explicit ``request_fd``
-parameter.
-
-Request Allocation
-------------------
-
-User-space allocates requests using :ref:`MEDIA_IOC_REQUEST_ALLOC`
-for the media device node. This returns a file descriptor representing the
-request. Typically, several such requests will be allocated.
-
-Request Preparation
--------------------
-
-Standard V4L2 ioctls can then receive a request file descriptor to express the
-fact that the ioctl is part of said request, and is not to be applied
-immediately. See :ref:`MEDIA_IOC_REQUEST_ALLOC` for a list of ioctls that
-support this. Configurations set with a ``request_fd`` parameter are stored
-instead of being immediately applied, and buffers queued to a request do not
-enter the regular buffer queue until the request itself is queued.
-
-Request Submission
-------------------
-
-Once the configuration and buffers of the request are specified, it can be
-queued by calling :ref:`MEDIA_REQUEST_IOC_QUEUE` on the request file descriptor.
-A request must contain at least one buffer, otherwise ``ENOENT`` is returned.
-A queued request cannot be modified anymore.
-
-.. caution::
-   For :ref:`memory-to-memory devices <mem2mem>` you can use requests only for
-   output buffers, not for capture buffers. Attempting to add a capture buffer
-   to a request will result in an ``EBADR`` error.
-
-If the request contains configurations for multiple entities, individual drivers
-may synchronize so the requested pipeline's topology is applied before the
-buffers are processed. Media controller drivers do a best effort implementation
-since perfect atomicity may not be possible due to hardware limitations.
-
-.. caution::
-
-   It is not allowed to mix queuing requests with directly queuing buffers:
-   whichever method is used first locks this in place until
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called or the device is
-   :ref:`closed <func-close>`. Attempts to directly queue a buffer when earlier
-   a buffer was queued via a request or vice versa will result in an ``EBUSY``
-   error.
-
-Controls can still be set without a request and are applied immediately,
-regardless of whether a request is in use or not.
-
-.. caution::
-
-   Setting the same control through a request and also directly can lead to
-   undefined behavior!
-
-User-space can :ref:`poll() <request-func-poll>` a request file descriptor in
-order to wait until the request completes. A request is considered complete
-once all its associated buffers are available for dequeuing and all the
-associated controls have been updated with the values at the time of completion.
-Note that user-space does not need to wait for the request to complete to
-dequeue its buffers: buffers that are available halfway through a request can
-be dequeued independently of the request's state.
-
-A completed request contains the state of the device after the request was
-executed. User-space can query that state by calling
-:ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` with the request file
-descriptor. Calling :ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
-request that has been queued but not yet completed will return ``EBUSY``
-since the control values might be changed at any time by the driver while the
-request is in flight.
-
-.. _media-request-life-time:
-
-Recycling and Destruction
--------------------------
-
-Finally, a completed request can either be discarded or be reused. Calling
-:ref:`close() <request-func-close>` on a request file descriptor will make
-that file descriptor unusable and the request will be freed once it is no
-longer in use by the kernel. That is, if the request is queued and then the
-file descriptor is closed, then it won't be freed until the driver completed
-the request.
-
-The :ref:`MEDIA_REQUEST_IOC_REINIT` will clear a request's state and make it
-available again. No state is retained by this operation: the request is as
-if it had just been allocated.
-
-Example for a Codec Device
---------------------------
-
-For use-cases such as :ref:`codecs <mem2mem>`, the request API can be used
-to associate specific controls to
-be applied by the driver for the OUTPUT buffer, allowing user-space
-to queue many such buffers in advance. It can also take advantage of requests'
-ability to capture the state of controls when the request completes to read back
-information that may be subject to change.
-
-Put into code, after obtaining a request, user-space can assign controls and one
-OUTPUT buffer to it:
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-	struct v4l2_ext_controls ctrls;
-	int req_fd;
-	...
-	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
-		return errno;
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
-		return errno;
-	...
-	buf.type = V4L2_BUF_TYPE_VIDEO_OUTPUT;
-	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
-	buf.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_QBUF, &buf))
-		return errno;
-
-Note that it is not allowed to use the Request API for CAPTURE buffers
-since there are no per-frame settings to report there.
-
-Once the request is fully prepared, it can be queued to the driver:
-
-.. code-block:: c
-
-	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
-		return errno;
-
-User-space can then either wait for the request to complete by calling poll() on
-its file descriptor, or start dequeuing CAPTURE buffers. Most likely, it will
-want to get CAPTURE buffers as soon as possible and this can be done using a
-regular :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`:
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-
-	memset(&buf, 0, sizeof(buf));
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-	if (ioctl(codec_fd, VIDIOC_DQBUF, &buf))
-		return errno;
-
-Note that this example assumes for simplicity that for every OUTPUT buffer
-there will be one CAPTURE buffer, but this does not have to be the case.
-
-We can then, after ensuring that the request is completed via polling the
-request file descriptor, query control values at the time of its completion via
-a call to :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.
-This is particularly useful for volatile controls for which we want to
-query values as soon as the capture buffer is produced.
-
-.. code-block:: c
-
-	struct pollfd pfd = { .events = POLLPRI, .fd = req_fd };
-	poll(&pfd, 1, -1);
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_G_EXT_CTRLS, &ctrls))
-		return errno;
-
-Once we don't need the request anymore, we can either recycle it for reuse with
-:ref:`MEDIA_REQUEST_IOC_REINIT`...
-
-.. code-block:: c
-
-	if (ioctl(req_fd, MEDIA_REQUEST_IOC_REINIT))
-		return errno;
-
-... or close its file descriptor to completely dispose of it.
-
-.. code-block:: c
-
-	close(req_fd);
-
-Example for a Simple Capture Device
------------------------------------
-
-With a simple capture device, requests can be used to specify controls to apply
-for a given CAPTURE buffer.
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-	struct v4l2_ext_controls ctrls;
-	int req_fd;
-	...
-	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
-		return errno;
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(camera_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
-		return errno;
-	...
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
-	buf.request_fd = req_fd;
-	if (ioctl(camera_fd, VIDIOC_QBUF, &buf))
-		return errno;
-
-Once the request is fully prepared, it can be queued to the driver:
-
-.. code-block:: c
-
-	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
-		return errno;
-
-User-space can then dequeue buffers, wait for the request completion, query
-controls and recycle the request as in the M2M example above.

-``timeout``
-   Timeout to wait for events
-
-
-Description
-===========
-
-With the :c:func:`poll() <request-func-poll>` function applications can wait
-for a request to complete.
-
-On success :c:func:`poll() <request-func-poll>` returns the number of file
-descriptors that have been selected (that is, file descriptors for which the
-``revents`` field of the respective struct :c:type:`pollfd`
-is non-zero). Request file descriptor set the ``POLLPRI`` flag in ``revents``
-when the request was completed.  When the function times out it returns
-a value of zero, on failure it returns -1 and the ``errno`` variable is
-set appropriately.
-
-Attempting to poll for a request that is not yet queued will
-set the ``POLLERR`` flag in ``revents``.
-
-
-Return Value
-============
-
-On success, :c:func:`poll() <request-func-poll>` returns the number of
-structures which have non-zero ``revents`` fields, or zero if the call
-timed out. On error -1 is returned, and the ``errno`` variable is set
-appropriately:
-
-``EBADF``
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-``EFAULT``
-    ``ufds`` references an inaccessible memory area.
-
-``EINTR``
-    The call was interrupted by a signal.
-
-``EINVAL``
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-Introduction
-************
-
-LIRC stands for Linux Infrared Remote Control. The LIRC device interface is
-a bi-directional interface for transporting raw IR and decoded scancodes
-data between userspace and kernelspace. Fundamentally, it is just a chardev
-(/dev/lircX, for X = 0, 1, 2, ...), with a number of standard struct
-file_operations defined on it. With respect to transporting raw IR and
-decoded scancodes to and fro, the essential fops are read, write and ioctl.
-
-It is also possible to attach a BPF program to a LIRC device for decoding
-raw IR into scancodes.
-
-Example dmesg output upon a driver registering w/LIRC:
-
-.. code-block:: none
-
-    $ dmesg |grep lirc_dev
-    rc rc0: lirc_dev: driver mceusb registered at minor = 0, raw IR receiver, raw IR transmitter
-
-What you should see for a chardev:
-
-.. code-block:: none
-
-    $ ls -l /dev/lirc*
-    crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0
-
-Note that the package `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_
-contains tools for working with LIRC devices:
-
- - ir-ctl: can receive raw IR and transmit IR, as well as query LIRC
-   device features.
-
- - ir-keytable: can load keymaps; allows you to set IR kernel protocols; load
-   BPF IR decoders and test IR decoding. Some BPF IR decoders are also
-   provided.
-
-.. _lirc_modes:
-
-**********
-LIRC modes
-**********
-
-LIRC supports some modes of receiving and sending IR codes, as shown
-on the following table.
-
-.. _lirc-mode-scancode:
-.. _lirc-scancode-flag-toggle:
-.. _lirc-scancode-flag-repeat:
-
-``LIRC_MODE_SCANCODE``
-
-    This mode is for both sending and receiving IR.
-
-    For transmitting (aka sending), create a ``struct lirc_scancode`` with
-    the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
-    set to the :ref:`IR protocol <Remote_controllers_Protocols>`, and all other
-    members set to 0. Write this struct to the lirc device.
-
-    For receiving, you read ``struct lirc_scancode`` from the LIRC device.
-    The ``scancode`` field is set to the received scancode and the
-    :ref:`IR protocol <Remote_controllers_Protocols>` is set in
-    :c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
-    in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
-
-    The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
-    bit is set in protocols that support it (e.g. rc-5 and rc-6), or
-    ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
-    that support it (e.g. nec).
-
-    In the Sanyo and NEC protocol, if you hold a button on remote, rather than
-    repeating the entire scancode, the remote sends a shorter message with
-    no scancode, which just means button is held, a "repeat". When this is
-    received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
-    keycode is repeated.
-
-    With nec, there is no way to distinguish "button hold" from "repeatedly
-    pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
-    When a button is released and pressed again, the toggle bit is inverted.
-    If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
-
-    The ``timestamp`` field is filled with the time nanoseconds
-    (in ``CLOCK_MONOTONIC``) when the scancode was decoded.
-
-.. _lirc-mode-mode2:
-
-``LIRC_MODE_MODE2``
-
-    The driver returns a sequence of pulse and space codes to userspace,
-    as a series of u32 values.
-
-    This mode is used only for IR receive.
-
-    The upper 8 bits determine the packet type, and the lower 24 bits
-    the payload. Use ``LIRC_VALUE()`` macro to get the payload, and
-    the macro ``LIRC_MODE2()`` will give you the type, which
-    is one of:
-
-    ``LIRC_MODE2_PULSE``
-
-        Signifies the presence of IR in microseconds.
-
-    ``LIRC_MODE2_SPACE``
-
-        Signifies absence of IR in microseconds.
-
-    ``LIRC_MODE2_FREQUENCY``
-
-        If measurement of the carrier frequency was enabled with
-        :ref:`lirc_set_measure_carrier_mode` then this packet gives you
-        the carrier frequency in Hertz.
-
-    ``LIRC_MODE2_TIMEOUT``
-
-        If timeout reports are enabled with
-        :ref:`lirc_set_rec_timeout_reports`, when the timeout set with
-        :ref:`lirc_set_rec_timeout` expires due to no IR being detected,
-        this packet will be sent, with the number of microseconds with
-        no IR.
-
-.. _lirc-mode-pulse:
-
-``LIRC_MODE_PULSE``
-
-    In pulse mode, a sequence of pulse/space integer values are written to the
-    lirc device using :ref:`lirc-write`.
-
-    The values are alternating pulse and space lengths, in microseconds. The
-    first and last entry must be a pulse, so there must be an odd number
-    of entries.
-
-    This mode is used only for IR send.
-
-********************
-BPF based IR decoder
-********************
-
-The kernel has support for decoding the most common
-:ref:`IR protocols <Remote_controllers_Protocols>`, but there
-are many protocols which are not supported. To support these, it is possible
-to load an BPF program which does the decoding. This can only be done on
-LIRC devices which support reading raw IR.
-
-First, using the `bpf(2)`_ syscall with the ``BPF_LOAD_PROG`` argument,
-program must be loaded of type ``BPF_PROG_TYPE_LIRC_MODE2``. Once attached
-to the LIRC device, this program will be called for each pulse, space or
-timeout event on the LIRC device. The context for the BPF program is a
-pointer to a unsigned int, which is a :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`
-value. When the program has decoded the scancode, it can be submitted using
-the BPF functions ``bpf_rc_keydown()`` or ``bpf_rc_repeat()``. Mouse or pointer
-movements can be reported using ``bpf_rc_pointer_rel()``.
-
-Once you have the file descriptor for the ``BPF_PROG_TYPE_LIRC_MODE2`` BPF
-program, it can be attached to the LIRC device using the `bpf(2)`_ syscall.
-The target must be the file descriptor for the LIRC device, and the
-attach type must be ``BPF_LIRC_MODE2``. No more than 64 BPF programs can be
-attached to a single LIRC device at a time.

-    File descriptor returned by open().
-
-``timeout``
-    Timeout, in microseconds.
-
-
-Description
-===========
-
-Some devices have internal timers that can be used to detect when
-there's no IR activity for a long time. This can help lircd in
-detecting that a IR signal is finished and can speed up the decoding
-process. Returns an integer value with the minimum/maximum timeout
-that can be set.
-
-.. note::
-
-   Some devices have a fixed timeout, in that case
-   both ioctls will return the same value even though the timeout
-   cannot be changed via :ref:`LIRC_SET_REC_TIMEOUT`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-
-lirc-read - Read from a LIRC device
-
-
-Synopsis
-========
-
-.. code-block:: c
-
-    #include <unistd.h>
-
-
-.. c:function:: ssize_t read( int fd, void *buf, size_t count )
-    :name: lirc-read
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by ``open()``.
-
-``buf``
-   Buffer to be filled
-
-``count``
-   Max number of bytes to read
-
-Description
-===========
-
-:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
-descriptor ``fd`` into the buffer starting at ``buf``.  If ``count`` is zero,
-:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
-is greater than ``SSIZE_MAX``, the result is unspecified.
-
-The exact format of the data depends on what :ref:`lirc_modes` a driver
-uses. Use :ref:`lirc_get_features` to get the supported mode, and use
-:ref:`lirc_set_rec_mode` set the current active mode.
-
-The mode :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` is for raw IR,
-in which packets containing an unsigned int value describing an IR signal are
-read from the chardev.
-
-Alternatively, :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` can be available,
-in this mode scancodes which are either decoded by software decoders, or
-by hardware decoders. The :c:type:`rc_proto` member is set to the
-:ref:`IR protocol <Remote_controllers_Protocols>`
-used for transmission, and ``scancode`` to the decoded scancode,
-and the ``keycode`` set to the keycode or ``KEY_RESERVED``.
-
-
-Return Value
-============
-
-On success, the number of bytes read is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame.  On error, -1 is returned, and the ``errno``
-variable is set appropriately.

-********************************
-
-Name

-
-LIRC_SET_WIDEBAND_RECEIVER - enable wide band receiver.
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, LIRC_SET_WIDEBAND_RECEIVER, __u32 *enable )
-    :name: LIRC_SET_WIDEBAND_RECEIVER
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by open().
-
-``enable``
-    enable = 1 means enable wideband receiver, enable = 0 means disable
-    wideband receiver.
-
-
-Description
-===========
-
-Some receivers are equipped with special wide band receiver which is
-intended to be used to learn output of existing remote. This ioctl
-allows enabling or disabling it.
-
-This might be useful of receivers that have otherwise narrow band receiver
-that prevents them to be used with some remotes. Wide band receiver might
-also be more precise. On the other hand its disadvantage it usually
-reduced range of reception.
-
-.. note::
-
-    Wide band receiver might be implictly enabled if you enable
-    carrier reports. In that case it will be disabled as soon as you disable
-    carrier reports. Trying to disable wide band receiver while carrier
-    reports are active will do nothing.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-lirc-write - Write to a LIRC device
-

-========
-

-
-    #include <unistd.h>
-
-
-.. c:function:: ssize_t write( int fd, void *buf, size_t count )
-    :name: lirc-write
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by ``open()``.
-
-``buf``
-    Buffer with data to be written
-
-``count``
-    Number of bytes at the buffer
-
-Description
-===========
-
-:ref:`write() <lirc-write>` writes up to ``count`` bytes to the device
-referenced by the file descriptor ``fd`` from the buffer starting at
-``buf``.
-
-The exact format of the data depends on what mode a driver is in, use
-:ref:`lirc_get_features` to get the supported modes and use
-:ref:`lirc_set_send_mode` set the mode.
-
-When in :ref:`LIRC_MODE_PULSE <lirc-mode-PULSE>` mode, the data written to
-the chardev is a pulse/space sequence of integer values. Pulses and spaces
-are only marked implicitly by their position. The data must start and end
-with a pulse, therefore, the data must always include an uneven number of
-samples. The write function blocks until the data has been transmitted
-by the hardware. If more data is provided than the hardware can send, the
-driver returns ``EINVAL``.
-
-When in :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` mode, one
-``struct lirc_scancode`` must be written to the chardev at a time, else
-``EINVAL`` is returned. Set the desired scancode in the ``scancode`` member,
-and the :ref:`IR protocol <Remote_controllers_Protocols>` in the
-:c:type:`rc_proto`: member. All other members must be
-set to 0, else ``EINVAL`` is returned. If there is no protocol encoder
-for the protocol or the scancode is not valid for the specified protocol,
-``EINVAL`` is returned. The write function blocks until the scancode
-is transmitted by the hardware.
-
-
-Return Value
-============
-
-On success, the number of bytes written is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame.  On error, -1 is returned, and the ``errno``
-variable is set appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Introduction
-************
-
-Currently, most analog and digital devices have a Infrared input for
-remote controllers. Each manufacturer has their own type of control. It
-is not rare for the same manufacturer to ship different types of
-controls, depending on the device.
-
-A Remote Controller interface is mapped as a normal evdev/input
-interface, just like a keyboard or a mouse. So, it uses all ioctls
-already defined for any other input devices.
-
-However, remove controllers are more flexible than a normal input
-device, as the IR receiver (and/or transmitter) can be used in
-conjunction with a wide variety of different IR remotes.
-
-In order to allow flexibility, the Remote Controller subsystem allows
-controlling the RC-specific attributes via
-:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.

-
-*******************************
-Remote Controller's sysfs nodes
-*******************************
-
-As defined at ``Documentation/ABI/testing/sysfs-class-rc``, those are
-the sysfs nodes that control the Remote Controllers:
-
-
-.. _sys_class_rc:
-
-/sys/class/rc/
-==============
-
-The ``/sys/class/rc/`` class sub-directory belongs to the Remote
-Controller core and provides a sysfs interface for configuring infrared
-remote controller receivers.
-
-
-.. _sys_class_rc_rcN:
-
-/sys/class/rc/rcN/
-==================
-
-A ``/sys/class/rc/rcN`` directory is created for each remote control
-receiver device where N is the number of the receiver.
-
-
-.. _sys_class_rc_rcN_protocols:
-
-/sys/class/rc/rcN/protocols
-===========================
-
-Reading this file returns a list of available protocols, something like::
-
-	rc5 [rc6] nec jvc [sony]
-
-Enabled protocols are shown in [] brackets.
-
-Writing "+proto" will add a protocol to the list of enabled protocols.
-
-Writing "-proto" will remove a protocol from the list of enabled
-protocols.
-
-Writing "proto" will enable only "proto".
-
-Writing "none" will disable all protocols.
-
-Write fails with ``EINVAL`` if an invalid protocol combination or unknown
-protocol name is used.
-
-
-.. _sys_class_rc_rcN_filter:
-
-/sys/class/rc/rcN/filter
-========================
-
-Sets the scancode filter expected value.
-
-Use in combination with ``/sys/class/rc/rcN/filter_mask`` to set the
-expected value of the bits set in the filter mask. If the hardware
-supports it then scancodes which do not match the filter will be
-ignored. Otherwise the write will fail with an error.
-
-This value may be reset to 0 if the current protocol is altered.
-
-
-.. _sys_class_rc_rcN_filter_mask:
-
-/sys/class/rc/rcN/filter_mask
-=============================
-
-Sets the scancode filter mask of bits to compare. Use in combination
-with ``/sys/class/rc/rcN/filter`` to set the bits of the scancode which
-should be compared against the expected value. A value of 0 disables the
-filter to allow all valid scancodes to be processed.
-
-If the hardware supports it then scancodes which do not match the filter
-will be ignored. Otherwise the write will fail with an error.
-
-This value may be reset to 0 if the current protocol is altered.
-
-
-.. _sys_class_rc_rcN_wakeup_protocols:
-
-/sys/class/rc/rcN/wakeup_protocols
-==================================
-
-Reading this file returns a list of available protocols to use for the
-wakeup filter, something like::
-
-	rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce
-
-Note that protocol variants are listed, so ``nec``, ``sony``, ``rc-5``, ``rc-6``
-have their different bit length encodings listed if available.
-
-Note that all protocol variants are listed.
-
-The enabled wakeup protocol is shown in [] brackets.
-
-Only one protocol can be selected at a time.
-
-Writing "proto" will use "proto" for wakeup events.
-
-Writing "none" will disable wakeup.
-
-Write fails with ``EINVAL`` if an invalid protocol combination or unknown
-protocol name is used, or if wakeup is not supported by the hardware.
-
-
-.. _sys_class_rc_rcN_wakeup_filter:
-
-/sys/class/rc/rcN/wakeup_filter
-===============================
-
-Sets the scancode wakeup filter expected value. Use in combination with
-``/sys/class/rc/rcN/wakeup_filter_mask`` to set the expected value of
-the bits set in the wakeup filter mask to trigger a system wake event.
-
-If the hardware supports it and wakeup_filter_mask is not 0 then
-scancodes which match the filter will wake the system from e.g. suspend
-to RAM or power off. Otherwise the write will fail with an error.
-
-This value may be reset to 0 if the wakeup protocol is altered.
-
-
-.. _sys_class_rc_rcN_wakeup_filter_mask:

-Remote controller tables
-************************
-
-Unfortunately, for several years, there was no effort to create uniform
-IR keycodes for different devices. This caused the same IR keyname to be
-mapped completely differently on different IR devices. This resulted
-that the same IR keyname to be mapped completely different on different
-IR's. Due to that, V4L2 API now specifies a standard for mapping Media
-keys on IR.
-
-This standard should be used by both V4L/DVB drivers and userspace
-applications
-
-The modules register the remote as keyboard within the linux input
-layer. This means that the IR key strokes will look like normal keyboard
-key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event
-devices (CONFIG_INPUT_EVDEV) it is possible for applications to access
-the remote via /dev/input/event devices.

-Application Priority
-********************
-
-When multiple applications share a device it may be desirable to assign
-them different priorities. Contrary to the traditional "rm -rf /" school
-of thought, a video recording application could for example block other
-applications from changing video controls or switching the current TV
-channel. Another objective is to permit low priority applications
-working in background, which can be preempted by user controlled
-applications and automatically regain control of the device at a later
-time.
-
-Since these features cannot be implemented entirely in user space V4L2
-defines the :ref:`VIDIOC_G_PRIORITY <VIDIOC_G_PRIORITY>` and
-:ref:`VIDIOC_S_PRIORITY <VIDIOC_G_PRIORITY>` ioctls to request and
-query the access priority associate with a file descriptor. Opening a
-device assigns a medium priority, compatible with earlier versions of
-V4L2 and drivers not supporting these ioctls. Applications requiring a
-different priority will usually call :ref:`VIDIOC_S_PRIORITY
-<VIDIOC_G_PRIORITY>` after verifying the device with the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-Ioctls changing driver properties, such as
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>`, return an ``EBUSY`` error code
-after another application obtained higher priority.

-************************
-Audio Inputs and Outputs
-************************
-
-Audio inputs and outputs are physical connectors of a device. Video
-capture devices have inputs, output devices have outputs, zero or more
-each. Radio devices have no audio inputs or outputs. They have exactly
-one tuner which in fact *is* an audio source, but this API associates
-tuners with video inputs or outputs only, and radio devices have none of
-these. [#f1]_ A connector on a TV card to loop back the received audio
-signal to a sound card is not considered an audio output.
-
-Audio and video inputs and outputs are associated. Selecting a video
-source also selects an audio source. This is most evident when the video
-and audio source is a tuner. Further audio connectors can combine with
-more than one video input or output. Assumed two composite video inputs
-and two audio inputs exist, there may be up to four valid combinations.
-The relation of video and audio connectors is defined in the
-``audioset`` field of the respective struct
-:c:type:`v4l2_input` or struct
-:c:type:`v4l2_output`, where each bit represents the index
-number, starting at zero, of one audio input or output.
-
-To learn about the number and attributes of the available inputs and
-outputs applications can enumerate them with the
-:ref:`VIDIOC_ENUMAUDIO` and
-:ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` ioctl, respectively.
-The struct :c:type:`v4l2_audio` returned by the
-:ref:`VIDIOC_ENUMAUDIO` ioctl also contains signal
-status information applicable when the current audio input is queried.
-
-The :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
-:ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` ioctls report the current
-audio input and output, respectively.
-
-.. note::
-
-   Note that, unlike :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-   :ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` these ioctls return a
-   structure as :ref:`VIDIOC_ENUMAUDIO` and
-   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` do, not just an index.
-
-To select an audio input and change its properties applications call the
-:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` ioctl. To select an audio
-output (which presently has no changeable properties) applications call
-the :ref:`VIDIOC_S_AUDOUT <VIDIOC_G_AUDOUT>` ioctl.
-
-Drivers must implement all audio input ioctls when the device has
-multiple selectable audio inputs, all audio output ioctls when the
-device has multiple selectable audio outputs. When the device has any
-audio inputs or outputs the driver must set the ``V4L2_CAP_AUDIO`` flag
-in the struct :c:type:`v4l2_capability` returned by
-the :ref:`VIDIOC_QUERYCAP` ioctl.
-
-
-Example: Information about the current audio input
-==================================================
-
-.. code-block:: c
-
-    struct v4l2_audio audio;
-
-    memset(&audio, 0, sizeof(audio));
-
-    if (-1 == ioctl(fd, VIDIOC_G_AUDIO, &audio)) {
-	perror("VIDIOC_G_AUDIO");
-	exit(EXIT_FAILURE);
-    }
-
-    printf("Current input: %s\\n", audio.name);
-
-
-Example: Switching to the first audio input
-===========================================
-
-.. code-block:: c
-
-    struct v4l2_audio audio;
-
-    memset(&audio, 0, sizeof(audio)); /* clear audio.mode, audio.reserved */
-
-    audio.index = 0;
-
-    if (-1 == ioctl(fd, VIDIOC_S_AUDIO, &audio)) {
-	perror("VIDIOC_S_AUDIO");
-	exit(EXIT_FAILURE);
-    }
-
-.. [#f1]
-   Actually struct :c:type:`v4l2_audio` ought to have a
-   ``tuner`` field like struct :c:type:`v4l2_input`, not
-   only making the API more consistent but also permitting radio devices
-   with multiple tuners.

-Buffers
-*******
-
-A buffer contains data exchanged by application and driver using one of
-the Streaming I/O methods. In the multi-planar API, the data is held in
-planes, while the buffer structure acts as a container for the planes.
-Only pointers to buffers (planes) are exchanged, the data itself is not
-copied. These pointers, together with meta-information like timestamps
-or field parity, are stored in a struct :c:type:`v4l2_buffer`,
-argument to the :ref:`VIDIOC_QUERYBUF`,
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` and
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. In the multi-planar API,
-some plane-specific members of struct :c:type:`v4l2_buffer`,
-such as pointers and sizes for each plane, are stored in struct
-struct :c:type:`v4l2_plane` instead. In that case, struct
-struct :c:type:`v4l2_buffer` contains an array of plane structures.
-
-Dequeued video buffers come with timestamps. The driver decides at which
-part of the frame and with which clock the timestamp is taken. Please
-see flags in the masks ``V4L2_BUF_FLAG_TIMESTAMP_MASK`` and
-``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` in :ref:`buffer-flags`. These flags
-are always valid and constant across all buffers during the whole video
-stream. Changes in these flags may take place as a side effect of
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` or
-:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` however. The
-``V4L2_BUF_FLAG_TIMESTAMP_COPY`` timestamp type which is used by e.g. on
-mem-to-mem devices is an exception to the rule: the timestamp source
-flags are copied from the OUTPUT video buffer to the CAPTURE video
-buffer.
-
-
-Interactions between formats, controls and buffers
-==================================================
-
-V4L2 exposes parameters that influence the buffer size, or the way data is
-laid out in the buffer. Those parameters are exposed through both formats and
-controls. One example of such a control is the ``V4L2_CID_ROTATE`` control
-that modifies the direction in which pixels are stored in the buffer, as well
-as the buffer size when the selected format includes padding at the end of
-lines.
-
-The set of information needed to interpret the content of a buffer (e.g. the
-pixel format, the line stride, the tiling orientation or the rotation) is
-collectively referred to in the rest of this section as the buffer layout.
-
-Controls that can modify the buffer layout shall set the
-``V4L2_CTRL_FLAG_MODIFY_LAYOUT`` flag.
-
-Modifying formats or controls that influence the buffer size or layout require
-the stream to be stopped. Any attempt at such a modification while the stream
-is active shall cause the ioctl setting the format or the control to return
-the ``EBUSY`` error code. In that case drivers shall also set the
-``V4L2_CTRL_FLAG_GRABBED`` flag when calling
-:c:func:`VIDIOC_QUERYCTRL` or :c:func:`VIDIOC_QUERY_EXT_CTRL` for such a
-control while the stream is active.
-
-.. note::
-
-   The :c:func:`VIDIOC_S_SELECTION` ioctl can, depending on the hardware (for
-   instance if the device doesn't include a scaler), modify the format in
-   addition to the selection rectangle. Similarly, the
-   :c:func:`VIDIOC_S_INPUT`, :c:func:`VIDIOC_S_OUTPUT`, :c:func:`VIDIOC_S_STD`
-   and :c:func:`VIDIOC_S_DV_TIMINGS` ioctls can also modify the format and
-   selection rectangles. When those ioctls result in a buffer size or layout
-   change, drivers shall handle that condition as they would handle it in the
-   :c:func:`VIDIOC_S_FMT` ioctl in all cases described in this section.
-
-Controls that only influence the buffer layout can be modified at any time
-when the stream is stopped. As they don't influence the buffer size, no
-special handling is needed to synchronize those controls with buffer
-allocation and the ``V4L2_CTRL_FLAG_GRABBED`` flag is cleared once the
-stream is stopped.
-
-Formats and controls that influence the buffer size interact with buffer
-allocation. The simplest way to handle this is for drivers to always require
-buffers to be reallocated in order to change those formats or controls. In
-that case, to perform such changes, userspace applications shall first stop
-the video stream with the :c:func:`VIDIOC_STREAMOFF` ioctl if it is running
-and free all buffers with the :c:func:`VIDIOC_REQBUFS` ioctl if they are
-allocated. After freeing all buffers the ``V4L2_CTRL_FLAG_GRABBED`` flag
-for controls is cleared. The format or controls can then be modified, and
-buffers shall then be reallocated and the stream restarted. A typical ioctl
-sequence is
-
- #. VIDIOC_STREAMOFF
- #. VIDIOC_REQBUFS(0)
- #. VIDIOC_S_EXT_CTRLS
- #. VIDIOC_S_FMT
- #. VIDIOC_REQBUFS(n)
- #. VIDIOC_QBUF
- #. VIDIOC_STREAMON
-
-The second :c:func:`VIDIOC_REQBUFS` call will take the new format and control
-value into account to compute the buffer size to allocate. Applications can
-also retrieve the size by calling the :c:func:`VIDIOC_G_FMT` ioctl if needed.
-
-.. note::
-
-   The API doesn't mandate the above order for control (3.) and format (4.)
-   changes. Format and controls can be set in a different order, or even
-   interleaved, depending on the device and use case. For instance some
-   controls might behave differently for different pixel formats, in which
-   case the format might need to be set first.
-
-When reallocation is required, any attempt to modify format or controls that
-influences the buffer size while buffers are allocated shall cause the format
-or control set ioctl to return the ``EBUSY`` error. Any attempt to queue a
-buffer too small for the current format or controls shall cause the
-:c:func:`VIDIOC_QBUF` ioctl to return a ``EINVAL`` error.
-
-Buffer reallocation is an expensive operation. To avoid that cost, drivers can
-(and are encouraged to) allow format or controls that influence the buffer
-size to be changed with buffers allocated. In that case, a typical ioctl
-sequence to modify format and controls is
-
- #. VIDIOC_STREAMOFF
- #. VIDIOC_S_EXT_CTRLS
- #. VIDIOC_S_FMT
- #. VIDIOC_QBUF
- #. VIDIOC_STREAMON
-
-For this sequence to operate correctly, queued buffers need to be large enough
-for the new format or controls. Drivers shall return a ``ENOSPC`` error in
-response to format change (:c:func:`VIDIOC_S_FMT`) or control changes
-(:c:func:`VIDIOC_S_CTRL` or :c:func:`VIDIOC_S_EXT_CTRLS`) if buffers too small
-for the new format are currently queued. As a simplification, drivers are
-allowed to return a ``EBUSY`` error from these ioctls if any buffer is
-currently queued, without checking the queued buffers sizes.
-
-Additionally, drivers shall return a ``EINVAL`` error from the
-:c:func:`VIDIOC_QBUF` ioctl if the buffer being queued is too small for the
-current format or controls. Together, these requirements ensure that queued
-buffers will always be large enough for the configured format and controls.
-
-Userspace applications can query the buffer size required for a given format
-and controls by first setting the desired control values and then trying the
-desired format. The :c:func:`VIDIOC_TRY_FMT` ioctl will return the required
-buffer size.
-

-The :c:func:`VIDIOC_CREATE_BUFS` ioctl can then be used to allocate buffers
-based on the queried sizes (for instance by allocating a set of buffers large
-enough for all the desired formats and controls, or by allocating separate set
-of appropriately sized buffers for each use case).

-    :widths:       1 2 10
-
-    * - __u32
-      - ``index``
-      - Number of the buffer, set by the application except when calling
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, then it is set by the
-	driver. This field can range from zero to the number of buffers
-	allocated with the :ref:`VIDIOC_REQBUFS` ioctl
-	(struct :c:type:`v4l2_requestbuffers`
-	``count``), plus any buffers allocated with
-	:ref:`VIDIOC_CREATE_BUFS` minus one.
-    * - __u32
-      - ``type``
-      - Type of the buffer, same as struct
-	:c:type:`v4l2_format` ``type`` or struct
-	:c:type:`v4l2_requestbuffers` ``type``, set
-	by the application. See :c:type:`v4l2_buf_type`
-    * - __u32
-      - ``bytesused``
-      - The number of bytes occupied by the data in the buffer. It depends
-	on the negotiated data format and may change with each buffer for
-	compressed variable size data like JPEG images. Drivers must set
-	this field when ``type`` refers to a capture stream, applications
-	when it refers to an output stream. If the application sets this
-	to 0 for an output stream, then ``bytesused`` will be set to the
-	size of the buffer (see the ``length`` field of this struct) by
-	the driver. For multiplanar formats this field is ignored and the
-	``planes`` pointer is used instead.
-    * - __u32
-      - ``flags``
-      - Flags set by the application or driver, see :ref:`buffer-flags`.
-    * - __u32
-      - ``field``
-      - Indicates the field order of the image in the buffer, see
-	:c:type:`v4l2_field`. This field is not used when the buffer
-	contains VBI data. Drivers must set it when ``type`` refers to a
-	capture stream, applications when it refers to an output stream.
-    * - struct timeval
-      - ``timestamp``
-      - For capture streams this is time when the first data byte was
-	captured, as returned by the :c:func:`clock_gettime()` function
-	for the relevant clock id; see ``V4L2_BUF_FLAG_TIMESTAMP_*`` in
-	:ref:`buffer-flags`. For output streams the driver stores the
-	time at which the last data byte was actually sent out in the
-	``timestamp`` field. This permits applications to monitor the
-	drift between the video and system clock. For output streams that
-	use ``V4L2_BUF_FLAG_TIMESTAMP_COPY`` the application has to fill
-	in the timestamp which will be copied by the driver to the capture
-	stream.
-    * - struct :c:type:`v4l2_timecode`
-      - ``timecode``
-      - When the ``V4L2_BUF_FLAG_TIMECODE`` flag is set in ``flags``, this
-	structure contains a frame timecode. In
-	:c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
-	bottom field contain the same timecode. Timecodes are intended to
-	help video editing and are typically recorded on video tapes, but
-	also embedded in compressed formats like MPEG. This field is
-	independent of the ``timestamp`` and ``sequence`` fields.
-    * - __u32
-      - ``sequence``
-      - Set by the driver, counting the frames (not fields!) in sequence.
-	This field is set for both input and output devices.
-    * - :cspan:`2`
-
-	In :c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
-	bottom field have the same sequence number. The count starts at
-	zero and includes dropped or repeated frames. A dropped frame was
-	received by an input device but could not be stored due to lack of
-	free buffer space. A repeated frame was displayed again by an
-	output device because the application did not pass new data in
-	time.
-
-	.. note::
-
-	   This may count the frames received e.g. over USB, without
-	   taking into account the frames dropped by the remote hardware due
-	   to limited compression throughput or bus bandwidth. These devices
-	   identify by not enumerating any video standards, see
-	   :ref:`standard`.
-
-    * - __u32
-      - ``memory``
-      - This field must be set by applications and/or drivers in

-	start of the device memory. The value is returned by the driver
-	and apart of serving as parameter to the
-	:ref:`mmap() <func-mmap>` function not useful for applications.
-	See :ref:`mmap` for details
-    * - unsigned long
-      - ``userptr``
-      - For the single-planar API and when ``memory`` is
-	``V4L2_MEMORY_USERPTR`` this is a pointer to the buffer (casted to
-	unsigned long type) in virtual memory, set by the application. See
-	:ref:`userp` for details.
-    * - struct v4l2_plane
-      - ``*planes``
-      - When using the multi-planar API, contains a userspace pointer to
-	an array of struct :c:type:`v4l2_plane`. The size of
-	the array should be put in the ``length`` field of this
-	struct :c:type:`v4l2_buffer` structure.
-    * - int
-      - ``fd``
-      - For the single-plane API and when ``memory`` is
-	``V4L2_MEMORY_DMABUF`` this is the file descriptor associated with
-	a DMABUF buffer.
-    * - }
-      -
-    * - __u32
-      - ``length``
-      - Size of the buffer (not the payload) in bytes for the
-	single-planar API. This is set by the driver based on the calls to
-	:ref:`VIDIOC_REQBUFS` and/or
-	:ref:`VIDIOC_CREATE_BUFS`. For the
-	multi-planar API the application sets this to the number of
-	elements in the ``planes`` array. The driver will fill in the
-	actual number of valid elements in that array.
-    * - __u32
-      - ``reserved2``
-      - A place holder for future extensions. Drivers and applications
-	must set this to 0.
-    * - __u32
-      - ``request_fd``
-      - The file descriptor of the request to queue the buffer to. If the flag
-        ``V4L2_BUF_FLAG_REQUEST_FD`` is set, then the buffer will be
-	queued to this request. If the flag is not set, then this field will
-	be ignored.
-
-	The ``V4L2_BUF_FLAG_REQUEST_FD`` flag and this field are only used by
-	:ref:`ioctl VIDIOC_QBUF <VIDIOC_QBUF>` and ignored by other ioctls that
-	take a :c:type:`v4l2_buffer` as argument.
-
-	Applications should not set ``V4L2_BUF_FLAG_REQUEST_FD`` for any ioctls
-	other than :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`.
-
-	If the device does not support requests, then ``EBADR`` will be returned.
-	If requests are supported but an invalid request file descriptor is
-	given, then ``EINVAL`` will be returned.

-
-      - ``V4L2_BUF_FLAG_MAPPED``
-      - 0x00000001
-      - The buffer resides in device memory and has been mapped into the
-	application's address space, see :ref:`mmap` for details.
-	Drivers set or clear this flag when the
-	:ref:`VIDIOC_QUERYBUF`,
-	:ref:`VIDIOC_QBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Set by the
-	driver.
-    * .. _`V4L2-BUF-FLAG-QUEUED`:
-
-      - ``V4L2_BUF_FLAG_QUEUED``
-      - 0x00000002
-      - Internally drivers maintain two buffer queues, an incoming and
-	outgoing queue. When this flag is set, the buffer is currently on
-	the incoming queue. It automatically moves to the outgoing queue
-	after the buffer has been filled (capture devices) or displayed
-	(output devices). Drivers set or clear this flag when the
-	``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
-	the ``VIDIOC_QBUF``\ ioctl it is always set and after
-	``VIDIOC_DQBUF`` always cleared.
-    * .. _`V4L2-BUF-FLAG-DONE`:
-
-      - ``V4L2_BUF_FLAG_DONE``
-      - 0x00000004
-      - When this flag is set, the buffer is currently on the outgoing
-	queue, ready to be dequeued from the driver. Drivers set or clear
-	this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
-	calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
-	cleared. Of course a buffer cannot be on both queues at the same
-	time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
-	are mutually exclusive. They can be both cleared however, then the
-	buffer is in "dequeued" state, in the application domain so to
-	say.
-    * .. _`V4L2-BUF-FLAG-ERROR`:
-
-      - ``V4L2_BUF_FLAG_ERROR``
-      - 0x00000040
-      - When this flag is set, the buffer has been dequeued successfully,
-	although the data might have been corrupted. This is recoverable,
-	streaming may continue as normal and the buffer may be reused
-	normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is
-	called.
-    * .. _`V4L2-BUF-FLAG-IN-REQUEST`:
-
-      - ``V4L2_BUF_FLAG_IN_REQUEST``
-      - 0x00000080
-      - This buffer is part of a request that hasn't been queued yet.
-    * .. _`V4L2-BUF-FLAG-KEYFRAME`:
-
-      - ``V4L2_BUF_FLAG_KEYFRAME``
-      - 0x00000008
-      - Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
-	ioctl. It may be set by video capture devices when the buffer
-	contains a compressed image which is a key frame (or field), i. e.
-	can be decompressed on its own. Also known as an I-frame.
-	Applications can set this bit when ``type`` refers to an output
-	stream.
-    * .. _`V4L2-BUF-FLAG-PFRAME`:
-
-      - ``V4L2_BUF_FLAG_PFRAME``
-      - 0x00000010
-      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames
-	or fields which contain only differences to a previous key frame.
-	Applications can set this bit when ``type`` refers to an output
-	stream.
-    * .. _`V4L2-BUF-FLAG-BFRAME`:
-
-      - ``V4L2_BUF_FLAG_BFRAME``
-      - 0x00000020
-      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
-	predicted frame or field which contains only the differences
-	between the current frame and both the preceding and following key
-	frames to specify its content. Applications can set this bit when
-	``type`` refers to an output stream.
-    * .. _`V4L2-BUF-FLAG-TIMECODE`:
-
-      - ``V4L2_BUF_FLAG_TIMECODE``
-      - 0x00000100
-      - The ``timecode`` field is valid. Drivers set or clear this flag
-	when the ``VIDIOC_DQBUF`` ioctl is called. Applications can set
-	this bit and the corresponding ``timecode`` structure when
-	``type`` refers to an output stream.
-    * .. _`V4L2-BUF-FLAG-PREPARED`:
-
-      - ``V4L2_BUF_FLAG_PREPARED``
-      - 0x00000400
-      - The buffer has been prepared for I/O and can be queued by the
-	application. Drivers set or clear this flag when the
-	:ref:`VIDIOC_QUERYBUF`,
-	:ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
-	:ref:`VIDIOC_QBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
-    * .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
-
-      - ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
-      - 0x00000800
-      - Caches do not have to be invalidated for this buffer. Typically
-	applications shall use this flag if the data captured in the
-	buffer is not going to be touched by the CPU, instead the buffer
-	will, probably, be passed on to a DMA-capable hardware unit for
-	further processing or output.
-    * .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
-
-      - ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
-      - 0x00001000
-      - Caches do not have to be cleaned for this buffer. Typically
-	applications shall use this flag for output buffers if the data in
-	this buffer has not been created by the CPU but by some
-	DMA-capable unit, in which case caches have not been used.
-    * .. _`V4L2-BUF-FLAG-M2M-HOLD-CAPTURE-BUF`:
-
-      - ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF``
-      - 0x00000200
-      - Only valid if ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` is
-	set. It is typically used with stateless decoders where multiple
-	output buffers each decode to a slice of the decoded frame.
-	Applications can set this flag when queueing the output buffer
-	to prevent the driver from dequeueing the capture buffer after
-	the output buffer has been decoded (i.e. the capture buffer is
-	'held'). If the timestamp of this output buffer differs from that
-	of the previous output buffer, then that indicates the start of a
-	new frame and the previously held capture buffer is dequeued.
-    * .. _`V4L2-BUF-FLAG-LAST`:
-
-      - ``V4L2_BUF_FLAG_LAST``
-      - 0x00100000
-      - Last buffer produced by the hardware. mem2mem codec drivers set
-	this flag on the capture queue for the last buffer when the
-	:ref:`VIDIOC_QUERYBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
-	hardware limitations, the last buffer may be empty. In this case
-	the driver will set the ``bytesused`` field to 0, regardless of
-	the format. Any Any subsequent call to the
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
-	but return an ``EPIPE`` error code.
-    * .. _`V4L2-BUF-FLAG-REQUEST-FD`:
-
-      - ``V4L2_BUF_FLAG_REQUEST_FD``
-      - 0x00800000
-      - The ``request_fd`` field contains a valid file descriptor.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
-      - 0x0000e000
-      - Mask for timestamp types below. To test the timestamp type, mask
-	out bits not belonging to timestamp type by performing a logical
-	and operation with buffer flags and timestamp mask.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
-      - 0x00000000
-      - Unknown timestamp type. This type is used by drivers before Linux
-	3.9 and may be either monotonic (see below) or realtime (wall
-	clock). Monotonic clock has been favoured in embedded systems
-	whereas most of the drivers use the realtime clock. Either kinds
-	of timestamps are available in user space via
-	:c:func:`clock_gettime` using clock IDs ``CLOCK_MONOTONIC``
-	and ``CLOCK_REALTIME``, respectively.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
-      - 0x00002000
-      - The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
-	clock. To access the same clock outside V4L2, use
-	:c:func:`clock_gettime`.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
-      - 0x00004000
-      - The CAPTURE buffer timestamp has been taken from the corresponding
-	OUTPUT buffer. This flag applies only to mem2mem devices.
-    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
-
-      - ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
-      - 0x00070000
-      - Mask for timestamp sources below. The timestamp source defines the
-	point of time the timestamp is taken in relation to the frame.
-	Logical 'and' operation between the ``flags`` field and
-	``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` produces the value of the
-	timestamp source. Applications must set the timestamp source when
-	``type`` refers to an output stream and
-	``V4L2_BUF_FLAG_TIMESTAMP_COPY`` is set.
-    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-EOF`:
-
-      - ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
-      - 0x00000000
-      - End Of Frame. The buffer timestamp has been taken when the last
-	pixel of the frame has been received or the last pixel of the
-	frame has been transmitted. In practice, software generated
-	timestamps will typically be read from the clock a small amount of

-****************************
-Defining Colorspaces in V4L2
-****************************
-
-In V4L2 colorspaces are defined by four values. The first is the
-colorspace identifier (enum :c:type:`v4l2_colorspace`)
-which defines the chromaticities, the default transfer function, the
-default Y'CbCr encoding and the default quantization method. The second
-is the transfer function identifier (enum
-:c:type:`v4l2_xfer_func`) to specify non-standard
-transfer functions. The third is the Y'CbCr encoding identifier (enum
-:c:type:`v4l2_ycbcr_encoding`) to specify
-non-standard Y'CbCr encodings and the fourth is the quantization
-identifier (enum :c:type:`v4l2_quantization`) to
-specify non-standard quantization methods. Most of the time only the
-colorspace field of struct :c:type:`v4l2_pix_format`
-or struct :c:type:`v4l2_pix_format_mplane`
-needs to be filled in.
-
-.. _hsv-colorspace:
-
-On :ref:`HSV formats <hsv-formats>` the *Hue* is defined as the angle on
-the cylindrical color representation. Usually this angle is measured in
-degrees, i.e. 0-360. When we map this angle value into 8 bits, there are
-two basic ways to do it: Divide the angular value by 2 (0-179), or use the
-whole range, 0-255, dividing the angular value by 1.41. The enum
-:c:type:`v4l2_hsv_encoding` specifies which encoding is used.
-
-.. note:: The default R'G'B' quantization is full range for all
-   colorspaces except for BT.2020 which uses limited range R'G'B'
-   quantization.

-Colorspace SMPTE 170M (V4L2_COLORSPACE_SMPTE170M)
-=================================================
-
-The :ref:`smpte170m` standard defines the colorspace used by NTSC and
-PAL and by SDTV in general. The default transfer function is
-``V4L2_XFER_FUNC_709``. The default Y'CbCr encoding is
-``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited
-range. The chromaticities of the primary colors and the white reference
-are:

-
-.. flat-table:: SMPTE 170M Chromaticities

-
-    * - Color
-      - x

-      - 0.070
-    * - White Reference (D65)
-      - 0.3127
-      - 0.3290
-
-
-The red, green and blue chromaticities are also often referred to as the
-SMPTE C set, so this colorspace is sometimes called SMPTE C as well.
-
-The transfer function defined for SMPTE 170M is the same as the one
-defined in Rec. 709.
-
-.. math::
-
-    L' = -1.099(-L)^{0.45} + 0.099 \text{, for } L \le-0.018
-
-    L' = 4.5L \text{, for } -0.018 < L < 0.018
-
-    L' = 1.099L^{0.45} - 0.099 \text{, for } L \ge 0.018
-
-Inverse Transfer function:
-
-.. math::
-
-    L = -\left( \frac{L' - 0.099}{-1.099} \right) ^{\frac{1}{0.45}} \text{, for } L' \le -0.081
-
-    L = \frac{L'}{4.5} \text{, for } -0.081 < L' < 0.081
-
-    L = \left(\frac{L' + 0.099}{1.099}\right)^{\frac{1}{0.45} } \text{, for } L' \ge 0.081
-
-The luminance (Y') and color difference (Cb and Cr) are obtained with
-the following ``V4L2_YCBCR_ENC_601`` encoding:
-
-.. math::
-
-    Y' = 0.2990R' + 0.5870G' + 0.1140B'
-
-    Cb = -0.1687R' - 0.3313G' + 0.5B'
-
-    Cr = 0.5R' - 0.4187G' - 0.0813B'
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5]. This conversion to Y'CbCr is identical to the one defined in
-the :ref:`itu601` standard and this colorspace is sometimes called
-BT.601 as well, even though BT.601 does not mention any color primaries.
-
-The default quantization is limited range, but full range is possible
-although rarely seen.
-
-
-.. _col-rec709:
-
-Colorspace Rec. 709 (V4L2_COLORSPACE_REC709)
-============================================
-
-The :ref:`itu709` standard defines the colorspace used by HDTV in
-general. The default transfer function is ``V4L2_XFER_FUNC_709``. The
-default Y'CbCr encoding is ``V4L2_YCBCR_ENC_709``. The default Y'CbCr
-quantization is limited range. The chromaticities of the primary colors
-and the white reference are:

-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range

-
-The default quantization is limited range, but full range is possible
-although rarely seen.
-
-The ``V4L2_YCBCR_ENC_709`` encoding described above is the default for
-this colorspace, but it can be overridden with ``V4L2_YCBCR_ENC_601``,
-in which case the BT.601 Y'CbCr encoding is used.
-
-Two additional extended gamut Y'CbCr encodings are also possible with
-this colorspace:
-
-The xvYCC 709 encoding (``V4L2_YCBCR_ENC_XV709``, :ref:`xvycc`) is
-similar to the Rec. 709 encoding, but it allows for R', G' and B' values
-that are outside the range [0…1]. The resulting Y', Cb and Cr values are
-scaled and offset according to the limited range formula:
-
-.. math::
-
-    Y' = \frac{219}{256} * (0.2126R' + 0.7152G' + 0.0722B') + \frac{16}{256}
-
-    Cb = \frac{224}{256} * (-0.1146R' - 0.3854G' + 0.5B')
-
-    Cr = \frac{224}{256} * (0.5R' - 0.4542G' - 0.0458B')
-
-The xvYCC 601 encoding (``V4L2_YCBCR_ENC_XV601``, :ref:`xvycc`) is
-similar to the BT.601 encoding, but it allows for R', G' and B' values
-that are outside the range [0…1]. The resulting Y', Cb and Cr values are
-scaled and offset according to the limited range formula:
-
-.. math::
-
-    Y' = \frac{219}{256} * (0.2990R' + 0.5870G' + 0.1140B') + \frac{16}{256}
-
-    Cb = \frac{224}{256} * (-0.1687R' - 0.3313G' + 0.5B')
-
-    Cr = \frac{224}{256} * (0.5R' - 0.4187G' - 0.0813B')
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5] and quantized without further scaling or offsets.
-The non-standard xvYCC 709 or xvYCC 601 encodings can be
-used by selecting ``V4L2_YCBCR_ENC_XV709`` or ``V4L2_YCBCR_ENC_XV601``.
-As seen by the xvYCC formulas these encodings always use limited range quantization,
-there is no full range variant. The whole point of these extended gamut encodings
-is that values outside the limited range are still valid, although they
-map to R', G' and B' values outside the [0…1] range and are therefore outside
-the Rec. 709 colorspace gamut.

-formats. The chromaticities of the primary colors and the white
-reference are identical to sRGB. The transfer function use is
-``V4L2_XFER_FUNC_SRGB``. The Y'CbCr encoding is ``V4L2_YCBCR_ENC_601``
-with full range quantization where Y' is scaled to [0…255] and Cb/Cr are
-scaled to [-128…128] and then clipped to [-128…127].
-
-.. note::
-
-   The JPEG standard does not actually store colorspace
-   information. So if something other than sRGB is used, then the driver
-   will have to set that information explicitly. Effectively
-   ``V4L2_COLORSPACE_JPEG`` can be considered to be an abbreviation for
-   ``V4L2_COLORSPACE_SRGB``, ``V4L2_YCBCR_ENC_601`` and
-   ``V4L2_QUANTIZATION_FULL_RANGE``.

-Transfer Function SMPTE 2084 (V4L2_XFER_FUNC_SMPTE2084)
-=======================================================
-
-The :ref:`smpte2084` standard defines the transfer function used by
-High Dynamic Range content.
-
-Constants:
-    m1 = (2610 / 4096) / 4
-
-    m2 = (2523 / 4096) * 128
-
-    c1 = 3424 / 4096
-
-    c2 = (2413 / 4096) * 32
-
-    c3 = (2392 / 4096) * 32
-
-Transfer function:
-    L' = ((c1 + c2 * L\ :sup:`m1`) / (1 + c3 * L\ :sup:`m1`))\ :sup:`m2`
-
-Inverse Transfer function:
-    L = (max(L':sup:`1/m2` - c1, 0) / (c2 - c3 *
-    L'\ :sup:`1/m2`))\ :sup:`1/m1`
-
-Take care when converting between this transfer function and non-HDR transfer
-functions: the linear RGB values [0…1] of HDR content map to a luminance range
-of 0 to 10000 cd/m\ :sup:`2` whereas the linear RGB values of non-HDR (aka
-Standard Dynamic Range or SDR) map to a luminance range of 0 to 100 cd/m\ :sup:`2`.
-
-To go from SDR to HDR you will have to divide L by 100 first. To go in the other
-direction you will have to multiply L by 100. Of course, this clamps all
-luminance values over 100 cd/m\ :sup:`2` to 100 cd/m\ :sup:`2`.
-
-There are better methods, see e.g. :ref:`colimg` for more in-depth information
-about this.

-***********
-Colorspaces
-***********
-
-'Color' is a very complex concept and depends on physics, chemistry and
-biology. Just because you have three numbers that describe the 'red',
-'green' and 'blue' components of the color of a pixel does not mean that
-you can accurately display that color. A colorspace defines what it
-actually *means* to have an RGB value of e.g. (255, 0, 0). That is,
-which color should be reproduced on the screen in a perfectly calibrated
-environment.
-
-In order to do that we first need to have a good definition of color,
-i.e. some way to uniquely and unambiguously define a color so that
-someone else can reproduce it. Human color vision is trichromatic since
-the human eye has color receptors that are sensitive to three different
-wavelengths of light. Hence the need to use three numbers to describe
-color. Be glad you are not a mantis shrimp as those are sensitive to 12
-different wavelengths, so instead of RGB we would be using the
-ABCDEFGHIJKL colorspace...
-
-Color exists only in the eye and brain and is the result of how strongly
-color receptors are stimulated. This is based on the Spectral Power
-Distribution (SPD) which is a graph showing the intensity (radiant
-power) of the light at wavelengths covering the visible spectrum as it
-enters the eye. The science of colorimetry is about the relationship
-between the SPD and color as perceived by the human brain.
-
-Since the human eye has only three color receptors it is perfectly
-possible that different SPDs will result in the same stimulation of
-those receptors and are perceived as the same color, even though the SPD
-of the light is different.
-
-In the 1920s experiments were devised to determine the relationship
-between SPDs and the perceived color and that resulted in the CIE 1931
-standard that defines spectral weighting functions that model the
-perception of color. Specifically that standard defines functions that
-can take an SPD and calculate the stimulus for each color receptor.
-After some further mathematical transforms these stimuli are known as
-the *CIE XYZ tristimulus* values and these X, Y and Z values describe a
-color as perceived by a human unambiguously. These X, Y and Z values are
-all in the range [0…1].
-
-The Y value in the CIE XYZ colorspace corresponds to luminance. Often
-the CIE XYZ colorspace is transformed to the normalized CIE xyY
-colorspace:
-
-	x = X / (X + Y + Z)
-
-	y = Y / (X + Y + Z)
-
-The x and y values are the chromaticity coordinates and can be used to
-define a color without the luminance component Y. It is very confusing
-to have such similar names for these colorspaces. Just be aware that if
-colors are specified with lower case 'x' and 'y', then the CIE xyY
-colorspace is used. Upper case 'X' and 'Y' refer to the CIE XYZ
-colorspace. Also, y has nothing to do with luminance. Together x and y
-specify a color, and Y the luminance. That is really all you need to
-remember from a practical point of view. At the end of this section you
-will find reading resources that go into much more detail if you are
-interested.
-
-A monitor or TV will reproduce colors by emitting light at three
-different wavelengths, the combination of which will stimulate the color
-receptors in the eye and thus cause the perception of color.
-Historically these wavelengths were defined by the red, green and blue
-phosphors used in the displays. These *color primaries* are part of what
-defines a colorspace.
-
-Different display devices will have different primaries and some
-primaries are more suitable for some display technologies than others.
-This has resulted in a variety of colorspaces that are used for
-different display technologies or uses. To define a colorspace you need
-to define the three color primaries (these are typically defined as x, y
-chromaticity coordinates from the CIE xyY colorspace) but also the white
-reference: that is the color obtained when all three primaries are at
-maximum power. This determines the relative power or energy of the
-primaries. This is usually chosen to be close to daylight which has been
-defined as the CIE D65 Illuminant.
-
-To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
-Other colorspaces are defined by three chromaticity coordinates defined
-in the CIE xyY colorspace. Based on those a 3x3 matrix can be
-constructed that transforms CIE XYZ colors to colors in the new
-colorspace.
-
-Both the CIE XYZ and the RGB colorspace that are derived from the
-specific chromaticity primaries are linear colorspaces. But neither the
-eye, nor display technology is linear. Doubling the values of all
-components in the linear colorspace will not be perceived as twice the
-intensity of the color. So each colorspace also defines a transfer
-function that takes a linear color component value and transforms it to
-the non-linear component value, which is a closer match to the
-non-linear performance of both the eye and displays. Linear component
-values are denoted RGB, non-linear are denoted as R'G'B'. In general
-colors used in graphics are all R'G'B', except in openGL which uses
-linear RGB. Special care should be taken when dealing with openGL to
-provide linear RGB colors or to use the built-in openGL support to apply
-the inverse transfer function.
-
-The final piece that defines a colorspace is a function that transforms
-non-linear R'G'B' to non-linear Y'CbCr. This function is determined by
-the so-called luma coefficients. There may be multiple possible Y'CbCr
-encodings allowed for the same colorspace. Many encodings of color
-prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the
-human eye is more sensitive to differences in luminance than in color
-this encoding allows one to reduce the amount of color information
-compared to the luma data. Note that the luma (Y') is unrelated to the Y
-in the CIE XYZ colorspace. Also note that Y'CbCr is often called YCbCr
-or YUV even though these are strictly speaking wrong.
-
-Sometimes people confuse Y'CbCr as being a colorspace. This is not
-correct, it is just an encoding of an R'G'B' color into luma and chroma
-values. The underlying colorspace that is associated with the R'G'B'
-color is also associated with the Y'CbCr color.
-
-The final step is how the RGB, R'G'B' or Y'CbCr values are quantized.
-The CIE XYZ colorspace where X, Y and Z are in the range [0…1] describes
-all colors that humans can perceive, but the transform to another
-colorspace will produce colors that are outside the [0…1] range. Once
-clamped to the [0…1] range those colors can no longer be reproduced in
-that colorspace. This clamping is what reduces the extent or gamut of
-the colorspace. How the range of [0…1] is translated to integer values
-in the range of [0…255] (or higher, depending on the color depth) is
-called the quantization. This is *not* part of the colorspace
-definition. In practice RGB or R'G'B' values are full range, i.e. they
-use the full [0…255] range. Y'CbCr values on the other hand are limited
-range with Y' using [16…235] and Cb and Cr using [16…240].
-
-Unfortunately, in some cases limited range RGB is also used where the
-components use the range [16…235]. And full range Y'CbCr also exists
-using the [0…255] range.
-
-In order to correctly interpret a color you need to know the
-quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr
-encoding and the colorspace. From that information you can calculate the
-corresponding CIE XYZ color and map that again to whatever colorspace
-your display device uses.
-
-The colorspace definition itself consists of the three chromaticity
-primaries, the white reference chromaticity, a transfer function and the
-luma coefficients needed to transform R'G'B' to Y'CbCr. While some
-colorspace standards correctly define all four, quite often the
-colorspace standard only defines some, and you have to rely on other
-standards for the missing pieces. The fact that colorspaces are often a
-mix of different standards also led to very confusing naming conventions
-where the name of a standard was used to name a colorspace when in fact
-that standard was part of various other colorspaces as well.
-
-If you want to read more about colors and colorspaces, then the
-following resources are useful: :ref:`poynton` is a good practical
-book for video engineers, :ref:`colimg` has a much broader scope and
-describes many more aspects of color (physics, chemistry, biology,
-etc.). The
-`http://www.brucelindbloom.com <http://www.brucelindbloom.com>`__
-website is an excellent resource, especially with respect to the
-mathematics behind colorspace conversions. The wikipedia
-`CIE 1931 colorspace <http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space>`__
-article is also very useful.

-*************
-User Controls
-*************
-
-Devices typically have a number of user-settable controls such as
-brightness, saturation and so on, which would be presented to the user
-on a graphical user interface. But, different devices will have
-different controls available, and furthermore, the range of possible
-values, and the default value will vary from device to device. The
-control ioctls provide the information and a mechanism to create a nice
-user interface for these controls that will work correctly with any
-device.
-
-All controls are accessed using an ID value. V4L2 defines several IDs
-for specific purposes. Drivers can also implement their own custom
-controls using ``V4L2_CID_PRIVATE_BASE``  [#f1]_ and higher values. The
-pre-defined control IDs have the prefix ``V4L2_CID_``, and are listed in
-:ref:`control-id`. The ID is used when querying the attributes of a
-control, and when getting or setting the current value.
-
-Generally applications should present controls to the user without
-assumptions about their purpose. Each control comes with a name string
-the user is supposed to understand. When the purpose is non-intuitive
-the driver writer should provide a user manual, a user interface plug-in
-or a driver specific panel application. Predefined IDs were introduced
-to change a few controls programmatically, for example to mute a device
-during a channel switch.
-
-Drivers may enumerate different controls after switching the current
-video input or output, tuner or modulator, or audio input or output.
-Different in the sense of other bounds, another default and current
-value, step size or other menu items. A control with a certain *custom*
-ID can also change name and type.
-
-If a control is not applicable to the current configuration of the
-device (for example, it doesn't apply to the current video input)
-drivers set the ``V4L2_CTRL_FLAG_INACTIVE`` flag.
-
-Control values are stored globally, they do not change when switching
-except to stay within the reported bounds. They also do not change e. g.
-when the device is opened or closed, when the tuner radio frequency is
-changed or generally never without application request.
-
-V4L2 specifies an event mechanism to notify applications when controls
-change value (see
-:ref:`VIDIOC_SUBSCRIBE_EVENT`, event
-``V4L2_EVENT_CTRL``), panel applications might want to make use of that
-in order to always reflect the correct control value.
-
-All controls use machine endianness.

-.. _control-id:
-
-Control IDs
-===========
-
-``V4L2_CID_BASE``
-    First predefined ID, equal to ``V4L2_CID_BRIGHTNESS``.
-
-``V4L2_CID_USER_BASE``
-    Synonym of ``V4L2_CID_BASE``.
-
-``V4L2_CID_BRIGHTNESS`` ``(integer)``
-    Picture brightness, or more precisely, the black level.
-
-``V4L2_CID_CONTRAST`` ``(integer)``
-    Picture contrast or luma gain.
-
-``V4L2_CID_SATURATION`` ``(integer)``
-    Picture color saturation or chroma gain.
-
-``V4L2_CID_HUE`` ``(integer)``
-    Hue or color balance.
-
-``V4L2_CID_AUDIO_VOLUME`` ``(integer)``
-    Overall audio volume. Note some drivers also provide an OSS or ALSA
-    mixer interface.
-
-``V4L2_CID_AUDIO_BALANCE`` ``(integer)``
-    Audio stereo balance. Minimum corresponds to all the way left,
-    maximum to right.
-
-``V4L2_CID_AUDIO_BASS`` ``(integer)``
-    Audio bass adjustment.
-
-``V4L2_CID_AUDIO_TREBLE`` ``(integer)``
-    Audio treble adjustment.
-
-``V4L2_CID_AUDIO_MUTE`` ``(boolean)``
-    Mute audio, i. e. set the volume to zero, however without affecting
-    ``V4L2_CID_AUDIO_VOLUME``. Like ALSA drivers, V4L2 drivers must mute
-    at load time to avoid excessive noise. Actually the entire device
-    should be reset to a low power consumption state.
-
-``V4L2_CID_AUDIO_LOUDNESS`` ``(boolean)``
-    Loudness mode (bass boost).
-
-``V4L2_CID_BLACK_LEVEL`` ``(integer)``
-    Another name for brightness (not a synonym of
-    ``V4L2_CID_BRIGHTNESS``). This control is deprecated and should not
-    be used in new drivers and applications.
-
-``V4L2_CID_AUTO_WHITE_BALANCE`` ``(boolean)``
-    Automatic white balance (cameras).
-
-``V4L2_CID_DO_WHITE_BALANCE`` ``(button)``
-    This is an action control. When set (the value is ignored), the
-    device will do a white balance and then hold the current setting.
-    Contrast this with the boolean ``V4L2_CID_AUTO_WHITE_BALANCE``,
-    which, when activated, keeps adjusting the white balance.
-
-``V4L2_CID_RED_BALANCE`` ``(integer)``
-    Red chroma balance.
-
-``V4L2_CID_BLUE_BALANCE`` ``(integer)``
-    Blue chroma balance.
-
-``V4L2_CID_GAMMA`` ``(integer)``
-    Gamma adjust.
-
-``V4L2_CID_WHITENESS`` ``(integer)``
-    Whiteness for grey-scale devices. This is a synonym for
-    ``V4L2_CID_GAMMA``. This control is deprecated and should not be
-    used in new drivers and applications.
-
-``V4L2_CID_EXPOSURE`` ``(integer)``
-    Exposure (cameras). [Unit?]
-
-``V4L2_CID_AUTOGAIN`` ``(boolean)``
-    Automatic gain/exposure control.
-
-``V4L2_CID_GAIN`` ``(integer)``
-    Gain control.
-
-    Primarily used to control gain on e.g. TV tuners but also on
-    webcams. Most devices control only digital gain with this control
-    but on some this could include analogue gain as well. Devices that
-    recognise the difference between digital and analogue gain use
-    controls ``V4L2_CID_DIGITAL_GAIN`` and ``V4L2_CID_ANALOGUE_GAIN``.
-
-``V4L2_CID_HFLIP`` ``(boolean)``
-    Mirror the picture horizontally.
-
-``V4L2_CID_VFLIP`` ``(boolean)``
-    Mirror the picture vertically.
-
-.. _v4l2-power-line-frequency:
-
-``V4L2_CID_POWER_LINE_FREQUENCY`` ``(enum)``
-    Enables a power line frequency filter to avoid flicker. Possible
-    values for ``enum v4l2_power_line_frequency`` are:
-    ``V4L2_CID_POWER_LINE_FREQUENCY_DISABLED`` (0),
-    ``V4L2_CID_POWER_LINE_FREQUENCY_50HZ`` (1),
-    ``V4L2_CID_POWER_LINE_FREQUENCY_60HZ`` (2) and
-    ``V4L2_CID_POWER_LINE_FREQUENCY_AUTO`` (3).
-
-``V4L2_CID_HUE_AUTO`` ``(boolean)``
-    Enables automatic hue control by the device. The effect of setting
-    ``V4L2_CID_HUE`` while automatic hue control is enabled is
-    undefined, drivers should ignore such request.
-
-``V4L2_CID_WHITE_BALANCE_TEMPERATURE`` ``(integer)``
-    This control specifies the white balance settings as a color
-    temperature in Kelvin. A driver should have a minimum of 2800
-    (incandescent) to 6500 (daylight). For more information about color
-    temperature see
-    `Wikipedia <http://en.wikipedia.org/wiki/Color_temperature>`__.
-
-``V4L2_CID_SHARPNESS`` ``(integer)``

-	values above or below a certain threshold are inverted.
-    * - ``V4L2_COLORFX_SILHOUETTE``
-      - Silhouette (outline).
-    * - ``V4L2_COLORFX_VIVID``

-
-
-
-``V4L2_CID_COLORFX_CBCR`` ``(integer)``
-    Determines the Cb and Cr coefficients for ``V4L2_COLORFX_SET_CBCR``
-    color effect. Bits [7:0] of the supplied 32 bit value are
-    interpreted as Cr component, bits [15:8] as Cb component and bits
-    [31:16] must be zero.

-
-``V4L2_CID_ROTATE`` ``(integer)``
-    Rotates the image by specified angle. Common angles are 90, 270 and
-    180. Rotating the image to 90 and 270 will reverse the height and
-    width of the display window. It is necessary to set the new height
-    and width of the picture using the
-    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl according to the
-    rotation angle selected.
-
-``V4L2_CID_BG_COLOR`` ``(integer)``
-    Sets the background color on the current output device. Background
-    color needs to be specified in the RGB24 format. The supplied 32 bit
-    value is interpreted as bits 0-7 Red color information, bits 8-15
-    Green color information, bits 16-23 Blue color information and bits
-    24-31 must be zero.
-
-``V4L2_CID_ILLUMINATORS_1 V4L2_CID_ILLUMINATORS_2`` ``(boolean)``
-    Switch on or off the illuminator 1 or 2 of the device (usually a
-    microscope).
-
-``V4L2_CID_MIN_BUFFERS_FOR_CAPTURE`` ``(integer)``
-    This is a read-only control that can be read by the application and
-    used as a hint to determine the number of CAPTURE buffers to pass to
-    REQBUFS. The value is the minimum number of CAPTURE buffers that is
-    necessary for hardware to work.
-
-``V4L2_CID_MIN_BUFFERS_FOR_OUTPUT`` ``(integer)``
-    This is a read-only control that can be read by the application and
-    used as a hint to determine the number of OUTPUT buffers to pass to
-    REQBUFS. The value is the minimum number of OUTPUT buffers that is
-    necessary for hardware to work.
-
-.. _v4l2-alpha-component:
-
-``V4L2_CID_ALPHA_COMPONENT`` ``(integer)``
-    Sets the alpha color component. When a capture device (or capture
-    queue of a mem-to-mem device) produces a frame format that includes
-    an alpha component (e.g.
-    :ref:`packed RGB image formats <pixfmt-rgb>`) and the alpha value
-    is not defined by the device or the mem-to-mem input data this
-    control lets you select the alpha component value of all pixels.
-    When an output device (or output queue of a mem-to-mem device)
-    consumes a frame format that doesn't include an alpha component and
-    the device supports alpha channel processing this control lets you
-    set the alpha component value of all pixels for further processing
-    in the device.
-
-``V4L2_CID_LASTP1``
-    End of the predefined control IDs (currently
-    ``V4L2_CID_ALPHA_COMPONENT`` + 1).
-
-``V4L2_CID_PRIVATE_BASE``
-    ID of the first custom (driver specific) control. Applications
-    depending on particular custom controls should check the driver name
-    and version, see :ref:`querycap`.
-
-Applications can enumerate the available controls with the
-:ref:`VIDIOC_QUERYCTRL` and
-:ref:`VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>` ioctls, get and set a
-control value with the :ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls. Drivers must implement
-``VIDIOC_QUERYCTRL``, ``VIDIOC_G_CTRL`` and ``VIDIOC_S_CTRL`` when the
-device has one or more controls, ``VIDIOC_QUERYMENU`` when it has one or
-more menu type controls.

-   The use of ``V4L2_CID_PRIVATE_BASE`` is problematic because different
-   drivers may use the same ``V4L2_CID_PRIVATE_BASE`` ID for different
-   controls. This makes it hard to programmatically set such controls
-   since the meaning of the control with that ID is driver dependent. In
-   order to resolve this drivers use unique IDs and the
-   ``V4L2_CID_PRIVATE_BASE`` IDs are mapped to those unique IDs by the
-   kernel. Consider these ``V4L2_CID_PRIVATE_BASE`` IDs as aliases to
-   the real IDs.
-
-   Many applications today still use the ``V4L2_CID_PRIVATE_BASE`` IDs
-   instead of using :ref:`VIDIOC_QUERYCTRL` with
-   the ``V4L2_CTRL_FLAG_NEXT_CTRL`` flag to enumerate all IDs, so
-   support for ``V4L2_CID_PRIVATE_BASE`` is still around.

-*****************************************************
-Image Cropping, Insertion and Scaling -- the CROP API
-*****************************************************
-
-.. note::
-
-   The CROP API is mostly superseded by the newer :ref:`SELECTION API
-   <selection-api>`. The new API should be preferred in most cases,
-   with the exception of pixel aspect ratio detection, which is
-   implemented by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` and has no
-   equivalent in the SELECTION API. See :ref:`selection-vs-crop` for a
-   comparison of the two APIs.
-
-Some video capture devices can sample a subsection of the picture and
-shrink or enlarge it to an image of arbitrary size. We call these
-abilities cropping and scaling. Some video output devices can scale an
-image up or down and insert it at an arbitrary scan line and horizontal
-offset into a video signal.
-
-Applications can use the following API to select an area in the video
-signal, query the default area and the hardware limits.
-
-.. note::
-
-   Despite their name, the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`,
-   :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP
-   <VIDIOC_G_CROP>` ioctls apply to input as well as output devices.
-
-Scaling requires a source and a target. On a video capture or overlay
-device the source is the video signal, and the cropping ioctls determine
-the area actually sampled. The target are images read by the application
-or overlaid onto the graphics screen. Their size (and position for an
-overlay) is negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls.
-
-On a video output device the source are the images passed in by the
-application, and their size is again negotiated with the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctls, or may be encoded in a compressed video stream. The target is
-the video signal, and the cropping ioctls determine the area where the
-images are inserted.
-
-Source and target rectangles are defined even if the device does not
-support scaling or the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctls. Their size (and position
-where applicable) will be fixed in this case.
-
-.. note::
-
-   All capture and output devices that support the CROP or SELECTION
-   API will also support the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`
-   ioctl.

-Cropping Structures

-
-    Image Cropping, Insertion and Scaling
-
-    The cropping, insertion and scaling process
-
-
-
-For capture devices the coordinates of the top left corner, width and
-height of the area which can be sampled is given by the ``bounds``
-substructure of the struct :c:type:`v4l2_cropcap` returned
-by the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl. To support a wide
-range of hardware this specification does not define an origin or units.
-However by convention drivers should horizontally count unscaled samples
-relative to 0H (the leading edge of the horizontal sync pulse, see
-:ref:`vbi-hsync`). Vertically ITU-R line numbers of the first field
-(see ITU R-525 line numbering for :ref:`525 lines <vbi-525>` and for
-:ref:`625 lines <vbi-625>`), multiplied by two if the driver
-can capture both fields.
-
-The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by struct
-:c:type:`v4l2_crop` using the same coordinate system as
-struct :c:type:`v4l2_cropcap`. Applications can use the
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>`
-ioctls to get and set this rectangle. It must lie completely within the
-capture boundaries and the driver may further adjust the requested size
-and/or position according to hardware limitations.
-
-Each capture device has a default source rectangle, given by the
-``defrect`` substructure of struct
-:c:type:`v4l2_cropcap`. The center of this rectangle
-shall align with the center of the active picture area of the video
-signal, and cover what the driver writer considers the complete picture.
-Drivers shall reset the source rectangle to the default when the driver
-is first loaded, but not later.
-
-For output devices these structures and ioctls are used accordingly,
-defining the *target* rectangle where the images will be inserted into
-the video signal.
-
-
-Scaling Adjustments
-===================
-
-Video hardware can have various cropping, insertion and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in horizontal and vertical
-direction. Also it may not support scaling at all. At the same time the
-struct :c:type:`v4l2_crop` rectangle may have to be aligned,
-and both the source and target rectangles may have arbitrary upper and
-lower size limits. In particular the maximum ``width`` and ``height`` in
-struct :c:type:`v4l2_crop` may be smaller than the struct
-:c:type:`v4l2_cropcap`. ``bounds`` area. Therefore, as
-usual, drivers are expected to adjust the requested parameters and
-return the actual values selected.
-
-Applications can change the source or the target rectangle first, as
-they may prefer a particular image size or a certain area in the video
-signal. If the driver has to adjust both to satisfy hardware
-limitations, the last requested rectangle shall take priority, and the
-driver should preferably adjust the opposite one. The
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl however shall not change
-the driver state and therefore only adjust the requested rectangle.
-
-Suppose scaling on a video capture device is restricted to a factor 1:1
-or 2:1 in either direction and the target image size must be a multiple
-of 16 × 16 pixels. The source cropping rectangle is set to defaults,
-which are also the upper limit in this example, of 640 × 400 pixels at
-offset 0, 0. An application requests an image size of 300 × 225 pixels,
-assuming video will be scaled down from the "full picture" accordingly.
-The driver sets the image size to the closest possible values 304 × 224,
-then chooses the cropping rectangle closest to the requested size, that
-is 608 × 224 (224 × 2:1 would exceed the limit 400). The offset 0, 0 is
-still valid, thus unmodified. Given the default cropping rectangle
-reported by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` the application can
-easily propose another offset to center the cropping rectangle.
-
-Now the application may insist on covering an area using a picture
-aspect ratio closer to the original request, so it asks for a cropping
-rectangle of 608 × 456 pixels. The present scaling factors limit
-cropping to 640 × 384, so the driver returns the cropping size 608 × 384
-and adjusts the image size to closest possible 304 × 192.
-
-
-Examples
-========
-
-Source and target rectangles shall remain unchanged across closing and
-reopening a device, such that piping data into or out of a device will
-work without special preparations. More advanced applications should
-ensure the parameters are suitable before starting I/O.
-
-.. note::
-
-   On the next two examples, a video capture device is assumed;
-   change ``V4L2_BUF_TYPE_VIDEO_CAPTURE`` for other types of device.

-
-***********************
-Video Capture Interface
-***********************
-
-Video capture devices sample an analog video signal and store the
-digitized images in memory. Today nearly all devices can capture at full
-25 or 30 frames/second. With this interface applications can control the
-capture process and move images from the driver into user space.
-
-Conventionally V4L2 video capture devices are accessed through character
-device special files named ``/dev/video`` and ``/dev/video0`` to
-``/dev/video63`` with major number 81 and minor numbers 0 to 63.
-``/dev/video`` is typically a symbolic link to the preferred video
-device.
-
-.. note:: The same device file names are used for video output devices.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the video capture interface set the
-``V4L2_CAP_VIDEO_CAPTURE`` or ``V4L2_CAP_VIDEO_CAPTURE_MPLANE`` flag in
-the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
-functions they may also support the :ref:`video overlay <overlay>`
-(``V4L2_CAP_VIDEO_OVERLAY``) and the :ref:`raw VBI capture <raw-vbi>`
-(``V4L2_CAP_VBI_CAPTURE``) interface. At least one of the read/write or
-streaming I/O methods must be supported. Tuners and audio inputs are
-optional.
-
-
-Supplemental Functions
-======================
-
-Video capture devices shall support :ref:`audio input <audio>`,
-:ref:`tuner`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video input <video>` ioctls must be supported by all video
-capture devices.
-
-
-Image Format Negotiation
-========================
-
-The result of a capture operation is determined by cropping and image
-format parameters. The former select an area of the video picture to
-capture, the latter how images are stored in memory, i. e. in RGB or YUV
-format, the number of bits per pixel or width and height. Together they
-also define how images are scaled in the process.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then reading
-from it as if it was a plain file. Well written V4L2 applications ensure
-they really get what they want, including cropping and scaling.
-
-Cropping initialization at minimum requires to reset the parameters to
-defaults. An example is given in :ref:`crop`.
-
-To query the current image format applications set the ``type`` field of
-a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
-``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
-structure. Drivers fill the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member of the ``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_pix_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers may adjust the
-parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-does.
-
-Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
-can be used to learn about hardware limitations without disabling I/O or
-possibly time consuming hardware preparations.
-
-The contents of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_pix_format_mplane` are
-discussed in :ref:`pixfmt`. See also the specification of the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
-details. Video capture devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
-requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
-
-
-Reading Images
-==============
-
-A video capture device may support the :ref:`read() function <func-read>`
-and/or streaming (:ref:`memory mapping <func-mmap>` or
-:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

-***************
-Event Interface
-***************
-
-The V4L2 event interface provides a means for a user to get immediately
-notified on certain conditions taking place on a device. This might
-include start of frame or loss of signal events, for example. Changes in
-the value or state of a V4L2 control can also be reported through
-events.
-
-To receive events, the events the user is interested in first must be
-subscribed using the
-:ref:`VIDIOC_SUBSCRIBE_EVENT` ioctl. Once
-an event is subscribed, the events of subscribed types are dequeueable
-using the :ref:`VIDIOC_DQEVENT` ioctl. Events may be
-unsubscribed using VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event
-type V4L2_EVENT_ALL may be used to unsubscribe all the events the
-driver supports.
-
-The event subscriptions and event queues are specific to file handles.
-Subscribing an event on one file handle does not affect other file
-handles.
-
-The information on dequeueable events is obtained by using select or
-poll system calls on video devices. The V4L2 events use POLLPRI events
-on poll system call and exceptions on select system call.
-
-Starting with kernel 3.1 certain guarantees can be given with regards to
-events:
-
-1. Each subscribed event has its own internal dedicated event queue.
-   This means that flooding of one event type will not interfere with
-   other event types.
-
-2. If the internal event queue for a particular subscribed event becomes
-   full, then the oldest event in that queue will be dropped.
-
-3. Where applicable, certain event types can ensure that the payload of
-   the oldest event that is about to be dropped will be merged with the
-   payload of the next oldest event. Thus ensuring that no information
-   is lost, but only an intermediate step leading up to that
-   information. See the documentation for the event you want to
-   subscribe to whether this is applicable for that event or not.

-********************************
-Video Memory-To-Memory Interface
-********************************
-
-A V4L2 memory-to-memory device can compress, decompress, transform, or
-otherwise convert video data from one format into another format, in memory.
-Such memory-to-memory devices set the ``V4L2_CAP_VIDEO_M2M`` or
-``V4L2_CAP_VIDEO_M2M_MPLANE`` capability. Examples of memory-to-memory
-devices are codecs, scalers, deinterlacers or format converters (i.e.
-converting from YUV to RGB).
-
-A memory-to-memory video node acts just like a normal video node, but it
-supports both output (sending frames from memory to the hardware)
-and capture (receiving the processed frames from the hardware into
-memory) stream I/O. An application will have to setup the stream I/O for
-both sides and finally call :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-for both capture and output to start the hardware.
-
-Memory-to-memory devices function as a shared resource: you can
-open the video node multiple times, each application setting up their
-own properties that are local to the file handle, and each can use
-it independently from the others. The driver will arbitrate access to
-the hardware and reprogram it whenever another file handler gets access.
-This is different from the usual video node behavior where the video
-properties are global to the device (i.e. changing something through one
-file handle is visible through another file handle).
-
-One of the most common memory-to-memory device is the codec. Codecs
-are more complicated than most and require additional setup for
-their codec parameters. This is done through codec controls.
-See :ref:`mpeg-controls`. More details on how to use codec memory-to-memory
-devices are given in the following sections.

-******************
-Metadata Interface
-******************
-
-Metadata refers to any non-image data that supplements video frames with
-additional information. This may include statistics computed over the image,
-frame capture parameters supplied by the image source or device specific
-parameters for specifying how the device processes images. This interface is
-intended for transfer of metadata between the userspace and the hardware and
-control of that operation.
-
-The metadata interface is implemented on video device nodes. The device can be
-dedicated to metadata or can support both video and metadata as specified in its
-reported capabilities.
-
-Querying Capabilities
-=====================
-
-Device nodes supporting the metadata capture interface set the
-``V4L2_CAP_META_CAPTURE`` flag in the ``device_caps`` field of the
-:c:type:`v4l2_capability` structure returned by the :c:func:`VIDIOC_QUERYCAP`
-ioctl. That flag means the device can capture metadata to memory. Similarly,
-device nodes supporting metadata output interface set the
-``V4L2_CAP_META_OUTPUT`` flag in the ``device_caps`` field of
-:c:type:`v4l2_capability` structure. That flag means the device can read
-metadata from memory.
-
-At least one of the read/write or streaming I/O methods must be supported.
-
-
-Data Format Negotiation
-=======================
-
-The metadata device uses the :ref:`format` ioctls to select the capture format.
-The metadata buffer content format is bound to that selected format. In addition
-to the basic :ref:`format` ioctls, the :c:func:`VIDIOC_ENUM_FMT` ioctl must be
-supported as well.
-
-To use the :ref:`format` ioctls applications set the ``type`` field of the
-:c:type:`v4l2_format` structure to ``V4L2_BUF_TYPE_META_CAPTURE`` or to
-``V4L2_BUF_TYPE_META_OUTPUT`` and use the :c:type:`v4l2_meta_format` ``meta``
-member of the ``fmt`` union as needed per the desired operation. Both drivers
-and applications must set the remainder of the :c:type:`v4l2_format` structure
-to 0.

-******************************
-Video Output Overlay Interface
-******************************
-
-**Also known as On-Screen Display (OSD)**
-
-Some video output devices can overlay a framebuffer image onto the
-outgoing video signal. Applications can set up such an overlay using
-this interface, which borrows structures and ioctls of the
-:ref:`Video Overlay <overlay>` interface.
-
-The OSD function is accessible through the same character special file
-as the :ref:`Video Output <capture>` function.
-
-.. note::
-
-   The default function of such a ``/dev/video`` device is video
-   capturing or output. The OSD function is only available after calling
-   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the *Video Output Overlay* interface set the
-``V4L2_CAP_VIDEO_OUTPUT_OVERLAY`` flag in the ``capabilities`` field of
-struct :c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-
-Framebuffer
-===========
-
-Contrary to the *Video Overlay* interface the framebuffer is normally
-implemented on the TV card and not the graphics card. On Linux it is
-accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
-applications can find the corresponding framebuffer device by calling
-the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` ioctl. It returns, amongst
-other information, the physical address of the framebuffer in the
-``base`` field of struct :c:type:`v4l2_framebuffer`.
-The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
-address in the ``smem_start`` field of struct
-struct :c:type:`fb_fix_screeninfo`. The ``FBIOGET_FSCREENINFO``
-ioctl and struct :c:type:`fb_fix_screeninfo` are defined in
-the ``linux/fb.h`` header file.
-
-The width and height of the framebuffer depends on the current video
-standard. A V4L2 driver may reject attempts to change the video standard
-(or any other ioctl which would imply a framebuffer size change) with an
-``EBUSY`` error code until all applications closed the framebuffer device.
-
-Example: Finding a framebuffer device for OSD
----------------------------------------------
-
-.. code-block:: c
-
-    #include <linux/fb.h>
-
-    struct v4l2_framebuffer fbuf;
-    unsigned int i;
-    int fb_fd;
-
-    if (-1 == ioctl(fd, VIDIOC_G_FBUF, &fbuf)) {
-	perror("VIDIOC_G_FBUF");
-	exit(EXIT_FAILURE);
-    }
-
-    for (i = 0; i < 30; i++) {
-	char dev_name[16];
-	struct fb_fix_screeninfo si;
-
-	snprintf(dev_name, sizeof(dev_name), "/dev/fb%u", i);
-
-	fb_fd = open(dev_name, O_RDWR);
-	if (-1 == fb_fd) {
-	    switch (errno) {
-	    case ENOENT: /* no such file */
-	    case ENXIO:  /* no driver */
-		continue;
-
-	    default:
-		perror("open");
-		exit(EXIT_FAILURE);
-	    }
-	}
-
-	if (0 == ioctl(fb_fd, FBIOGET_FSCREENINFO, &si)) {
-	    if (si.smem_start == (unsigned long)fbuf.base)
-		break;
-	} else {
-	    /* Apparently not a framebuffer device. */
-	}
-
-	close(fb_fd);
-	fb_fd = -1;
-    }
-
-    /* fb_fd is the file descriptor of the framebuffer device
-       for the video output overlay, or -1 if no device was found. */
-
-
-Overlay Window and Scaling
-==========================
-
-The overlay is controlled by source and target rectangles. The source
-rectangle selects a subsection of the framebuffer image to be overlaid,
-the target rectangle an area in the outgoing video signal where the
-image will appear. Drivers may or may not support scaling, and arbitrary
-sizes and positions of these rectangles. Further drivers may support any
-(or none) of the clipping/blending methods defined for the
-:ref:`Video Overlay <overlay>` interface.
-
-A struct :c:type:`v4l2_window` defines the size of the
-source rectangle, its position in the framebuffer and the
-clipping/blending method to be used for the overlay. To get the current
-parameters applications set the ``type`` field of a struct
-:c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
-struct :c:type:`v4l2_window` substructure named ``win``. It is not
-possible to retrieve a previously programmed clipping list or bitmap.
-
-To program the source rectangle applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY``, initialize the ``win``
-substructure and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-The driver adjusts the parameters against hardware limits and returns
-the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
-the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
-about driver capabilities without actually changing driver state. Unlike
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
-
-A struct :c:type:`v4l2_crop` defines the size and position
-of the target rectangle. The scaling factor of the overlay is implied by
-the width and height given in struct :c:type:`v4l2_window`
-and struct :c:type:`v4l2_crop`. The cropping API applies to
-*Video Output* and *Video Output Overlay* devices in the same way as to
-*Video Capture* and *Video Overlay* devices, merely reversing the
-direction of the data flow. For more information see :ref:`crop`.
-
-
-Enabling Overlay
-================
-
-There is no V4L2 ioctl to enable or disable the overlay, however the
-framebuffer interface of the driver may support the ``FBIOBLANK`` ioctl.

-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
-functions they may also support the :ref:`raw VBI output <raw-vbi>`
-(``V4L2_CAP_VBI_OUTPUT``) interface. At least one of the read/write or
-streaming I/O methods must be supported. Modulators and audio outputs
-are optional.
-
-
-Supplemental Functions
-======================
-
-Video output devices shall support :ref:`audio output <audio>`,
-:ref:`modulator <tuner>`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video output <video>` ioctls must be supported by all video
-output devices.
-
-
-Image Format Negotiation
-========================
-
-The output is determined by cropping and image format parameters. The
-former select an area of the video picture where the image will appear,
-the latter how images are stored in memory, i. e. in RGB or YUV format,
-the number of bits per pixel or width and height. Together they also
-define how images are scaled in the process.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then writing
-to it as if it was a plain file. Well written V4L2 applications ensure
-they really get what they want, including cropping and scaling.
-
-Cropping initialization at minimum requires to reset the parameters to
-defaults. An example is given in :ref:`crop`.
-
-To query the current image format applications set the ``type`` field of
-a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT`` or ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``
-and call the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer
-to this structure. Drivers fill the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member of the ``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_pix_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers may adjust the
-parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-does.
-
-Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
-can be used to learn about hardware limitations without disabling I/O or
-possibly time consuming hardware preparations.
-
-The contents of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_pix_format_mplane` are
-discussed in :ref:`pixfmt`. See also the specification of the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
-details. Video output devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
-requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
-
-
-Writing Images
-==============
-
-A video output device may support the :ref:`write() function <rw>`
-and/or streaming (:ref:`memory mapping <mmap>` or
-:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

-***********************
-Video Overlay Interface
-***********************
-
-**Also known as Framebuffer Overlay or Previewing.**
-
-Video overlay devices have the ability to genlock (TV-)video into the
-(VGA-)video signal of a graphics card, or to store captured images
-directly in video memory of a graphics card, typically with clipping.
-This can be considerable more efficient than capturing images and
-displaying them by other means. In the old days when only nuclear power
-plants needed cooling towers this used to be the only way to put live
-video into a window.
-
-Video overlay devices are accessed through the same character special
-files as :ref:`video capture <capture>` devices.
-
-.. note::
-
-   The default function of a ``/dev/video`` device is video
-   capturing. The overlay function is only available after calling
-   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-The driver may support simultaneous overlay and capturing using the
-read/write and streaming I/O methods. If so, operation at the nominal
-frame rate of the video standard is not guaranteed. Frames may be
-directed away from overlay to capture, or one field may be used for
-overlay and the other for capture if the capture parameters permit this.
-
-Applications should use different file descriptors for capturing and
-overlay. This must be supported by all drivers capable of simultaneous
-capturing and overlay. Optionally these drivers may also permit
-capturing and overlay with a single file descriptor for compatibility
-with V4L and earlier versions of V4L2. [#f1]_
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the video overlay interface set the
-``V4L2_CAP_VIDEO_OVERLAY`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. The overlay I/O
-method specified below must be supported. Tuners and audio inputs are
-optional.
-
-
-Supplemental Functions
-======================
-
-Video overlay devices shall support :ref:`audio input <audio>`,
-:ref:`tuner`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video input <video>` and :ref:`video standard <standard>`
-ioctls must be supported by all video overlay devices.
-
-
-Setup
-=====
-
-Before overlay can commence applications must program the driver with
-frame buffer parameters, namely the address and size of the frame buffer
-and the image format, for example RGB 5:6:5. The
-:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
-:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls are available to get and
-set these parameters, respectively. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is
-privileged because it allows to set up DMA into physical memory,
-bypassing the memory protection mechanisms of the kernel. Only the
-superuser can change the frame buffer address and size. Users are not
-supposed to run TV applications as root or with SUID bit set. A small
-helper application with suitable privileges should query the graphics
-system and program the V4L2 driver at the appropriate time.
-
-Some devices add the video overlay to the output signal of the graphics
-card. In this case the frame buffer is not modified by the video device,
-and the frame buffer address and pixel format are not needed by the
-driver. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is not privileged. An application
-can check for this type of device by calling the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-ioctl.
-
-A driver may support any (or none) of five clipping/blending methods:
-
-1. Chroma-keying displays the overlaid image only where pixels in the
-   primary graphics surface assume a certain color.
-
-2. A bitmap can be specified where each bit corresponds to a pixel in
-   the overlaid image. When the bit is set, the corresponding video
-   pixel is displayed, otherwise a pixel of the graphics surface.
-
-3. A list of clipping rectangles can be specified. In these regions *no*
-   video is displayed, so the graphics surface can be seen here.
-
-4. The framebuffer has an alpha channel that can be used to clip or
-   blend the framebuffer with the video.
-
-5. A global alpha value can be specified to blend the framebuffer
-   contents with video images.
-
-When simultaneous capturing and overlay is supported and the hardware
-prohibits different image and frame buffer formats, the format requested
-first takes precedence. The attempt to capture
-(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) or overlay
-(:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`) may fail with an ``EBUSY`` error
-code or return accordingly modified parameters..
-
-
-Overlay Window
-==============
-
-The overlaid image is determined by cropping and overlay window
-parameters. The former select an area of the video picture to capture,
-the latter how images are overlaid and clipped. Cropping initialization
-at minimum requires to reset the parameters to defaults. An example is
-given in :ref:`crop`.
-
-The overlay window is described by a struct
-:c:type:`v4l2_window`. It defines the size of the image,
-its position over the graphics surface and the clipping to be applied.
-To get the current parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OVERLAY`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
-struct :c:type:`v4l2_window` substructure named ``win``. It is not
-possible to retrieve a previously programmed clipping list or bitmap.
-
-To program the overlay window applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OVERLAY``, initialize the ``win`` substructure and
-call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. The driver
-adjusts the parameters against hardware limits and returns the actual
-parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
-about driver capabilities without actually changing driver state. Unlike
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
-
-The scaling factor of the overlaid image is implied by the width and
-height given in struct :c:type:`v4l2_window` and the size
-of the cropping rectangle. For more information see :ref:`crop`.
-
-When simultaneous capturing and overlay is supported and the hardware
-prohibits different image and window sizes, the size requested first
-takes precedence. The attempt to capture or overlay as well
-(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) may fail with an ``EBUSY`` error
-code or return accordingly modified parameters.
-
-
-.. c:type:: v4l2_window
-
-struct v4l2_window
-------------------
-
-``struct v4l2_rect w``
-    Size and position of the window relative to the top, left corner of
-    the frame buffer defined with
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The window can extend the
-    frame buffer width and height, the ``x`` and ``y`` coordinates can
-    be negative, and it can lie completely outside the frame buffer. The
-    driver clips the window accordingly, or if that is not possible,
-    modifies its size and/or position.
-
-``enum v4l2_field field``
-    Applications set this field to determine which video field shall be
-    overlaid, typically one of ``V4L2_FIELD_ANY`` (0),
-    ``V4L2_FIELD_TOP``, ``V4L2_FIELD_BOTTOM`` or
-    ``V4L2_FIELD_INTERLACED``. Drivers may have to choose a different
-    field order and return the actual setting here.
-
-``__u32 chromakey``
-    When chroma-keying has been negotiated with
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` applications set this field
-    to the desired pixel value for the chroma key. The format is the
-    same as the pixel format of the framebuffer (struct
-    :c:type:`v4l2_framebuffer` ``fmt.pixelformat``
-    field), with bytes in host order. E. g. for
-    :ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR32>` the value should
-    be 0xRRGGBB on a little endian, 0xBBGGRR on a big endian host.
-
-``struct v4l2_clip * clips``
-    When chroma-keying has *not* been negotiated and
-    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
-    applications can set this field to point to an array of clipping
-    rectangles.
-
-    Like the window coordinates w, clipping rectangles are defined
-    relative to the top, left corner of the frame buffer. However
-    clipping rectangles must not extend the frame buffer width and
-    height, and they must not overlap. If possible applications
-    should merge adjacent rectangles. Whether this must create
-    x-y or y-x bands, or the order of rectangles, is not defined. When
-    clip lists are not supported the driver ignores this field. Its
-    contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-    are undefined.
-
-``__u32 clipcount``
-    When the application set the ``clips`` field, this field must
-    contain the number of clipping rectangles in the list. When clip
-    lists are not supported the driver ignores this field, its contents
-    after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are undefined. When clip lists are
-    supported but no clipping is desired this field must be set to zero.
-
-``void * bitmap``
-    When chroma-keying has *not* been negotiated and
-    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
-    applications can set this field to point to a clipping bit mask.
-
-It must be of the same size as the window, ``w.width`` and ``w.height``.
-Each bit corresponds to a pixel in the overlaid image, which is
-displayed only when the bit is *set*. Pixel coordinates translate to
-bits like:
-
-
-.. code-block:: c
-
-    ((__u8 *) bitmap)[w.width * y + x / 8] & (1 << (x & 7))
-
-where ``0`` ≤ x < ``w.width`` and ``0`` ≤ y <``w.height``. [#f2]_
-
-When a clipping bit mask is not supported the driver ignores this field,
-its contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are
-undefined. When a bit mask is supported but no clipping is desired this
-field must be set to ``NULL``.
-
-Applications need not create a clip list or bit mask. When they pass
-both, or despite negotiating chroma-keying, the results are undefined.
-Regardless of the chosen method, the clipping abilities of the hardware
-may be limited in quantity or quality. The results when these limits are
-exceeded are undefined. [#f3]_
-
-``__u8 global_alpha``
-    The global alpha value used to blend the framebuffer with video
-    images, if global alpha blending has been negotiated
-    (``V4L2_FBUF_FLAG_GLOBAL_ALPHA``, see
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`,
-    :ref:`framebuffer-flags`).
-
-.. note::
-
-   This field was added in Linux 2.6.23, extending the
-   structure. However the :ref:`VIDIOC_[G|S|TRY]_FMT <VIDIOC_G_FMT>`
-   ioctls, which take a pointer to a :c:type:`v4l2_format`
-   parent structure with padding bytes at the end, are not affected.
-
-
-.. c:type:: v4l2_clip
-
-struct v4l2_clip [#f4]_
------------------------
-
-``struct v4l2_rect c``
-    Coordinates of the clipping rectangle, relative to the top, left
-    corner of the frame buffer. Only window pixels *outside* all
-    clipping rectangles are displayed.
-
-``struct v4l2_clip * next``
-    Pointer to the next clipping rectangle, ``NULL`` when this is the last
-    rectangle. Drivers ignore this field, it cannot be used to pass a
-    linked list of clipping rectangles.
-
-
-.. c:type:: v4l2_rect
-
-struct v4l2_rect
-----------------
-
-``__s32 left``
-    Horizontal offset of the top, left corner of the rectangle, in
-    pixels.
-
-``__s32 top``
-    Vertical offset of the top, left corner of the rectangle, in pixels.
-    Offsets increase to the right and down.
-
-``__u32 width``
-    Width of the rectangle, in pixels.
-
-``__u32 height``
-    Height of the rectangle, in pixels.
-
-
-Enabling Overlay
-================
-
-To start or stop the frame buffer overlay applications call the
-:ref:`VIDIOC_OVERLAY` ioctl.
-
-.. [#f1]
-   A common application of two file descriptors is the XFree86
-   :ref:`Xv/V4L <xvideo>` interface driver and a V4L2 application.
-   While the X server controls video overlay, the application can take
-   advantage of memory mapping and DMA.
-
-   In the opinion of the designers of this API, no driver writer taking
-   the efforts to support simultaneous capturing and overlay will
-   restrict this ability by requiring a single file descriptor, as in
-   V4L and earlier versions of V4L2. Making this optional means
-   applications depending on two file descriptors need backup routines
-   to be compatible with all drivers, which is considerable more work
-   than using two fds in applications which do not. Also two fd's fit
-   the general concept of one file descriptor for each logical stream.
-   Hence as a complexity trade-off drivers *must* support two file
-   descriptors and *may* support single fd operation.
-
-.. [#f2]
-   Should we require ``w.width`` to be a multiple of eight?
-
-.. [#f3]
-   When the image is written into frame buffer memory it will be
-   undesirable if the driver clips out less pixels than expected,
-   because the application and graphics system are not aware these
-   regions need to be refreshed. The driver should clip out more pixels
-   or not write the image at all.
-
-.. [#f4]
-   The X Window system defines "regions" which are vectors of ``struct
-   BoxRec { short x1, y1, x2, y2; }`` with ``width = x2 - x1`` and
-   ``height = y2 - y1``, so one cannot pass X11 clip lists directly.

-
-This interface is intended for AM and FM (analog) radio receivers and

-
-Conventionally V4L2 radio devices are accessed through character device
-special files named ``/dev/radio`` and ``/dev/radio0`` to
-``/dev/radio63`` with major number 81 and minor numbers 64 to 127.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the radio interface set the ``V4L2_CAP_RADIO`` and

-
-
-Supplemental Functions
-======================
-
-Radio devices can support :ref:`controls <control>`, and must support
-the :ref:`tuner or modulator <tuner>` ioctls.
-
-They do not support the video input or output, audio input or output,

-
-
-Programming
-===========
-
-Radio devices may have a couple audio controls (as discussed in

-
-**********************
-Raw VBI Data Interface
-**********************
-
-VBI is an abbreviation of Vertical Blanking Interval, a gap in the
-sequence of lines of an analog video signal. During VBI no picture
-information is transmitted, allowing some time while the electron beam
-of a cathode ray tube TV returns to the top of the screen. Using an
-oscilloscope you will find here the vertical synchronization pulses and
-short data packages ASK modulated [#f1]_ onto the video signal. These are
-transmissions of services such as Teletext or Closed Caption.
-
-Subject of this interface type is raw VBI data, as sampled off a video
-signal, or to be added to a signal for output. The data format is
-similar to uncompressed video images, a number of lines times a number
-of samples per line, we call this a VBI image.
-
-Conventionally V4L2 VBI devices are accessed through character device
-special files named ``/dev/vbi`` and ``/dev/vbi0`` to ``/dev/vbi31``
-with major number 81 and minor numbers 224 to 255. ``/dev/vbi`` is
-typically a symbolic link to the preferred VBI device. This convention
-applies to both input and output devices.
-
-To address the problems of finding related video and VBI devices VBI
-capturing and output is also available as device function under
-``/dev/video``. To capture or output raw VBI data with these devices
-applications must call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-Accessed as ``/dev/vbi``, raw VBI capturing or output is the default
-device function.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the raw VBI capturing or output API set the
-``V4L2_CAP_VBI_CAPTURE`` or ``V4L2_CAP_VBI_OUTPUT`` flags, respectively,
-in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
-read/write, streaming or asynchronous I/O methods must be supported. VBI
-devices may or may not have a tuner or modulator.
-
-
-Supplemental Functions
-======================
-
-VBI devices shall support :ref:`video input or output <video>`,
-:ref:`tuner or modulator <tuner>`, and :ref:`controls <control>`
-ioctls as needed. The :ref:`video standard <standard>` ioctls provide
-information vital to program a VBI device, therefore must be supported.
-
-
-Raw VBI Format Negotiation
-==========================
-
-Raw VBI sampling abilities can vary, in particular the sampling
-frequency. To properly interpret the data V4L2 specifies an ioctl to
-query the sampling parameters. Moreover, to allow for some flexibility
-applications can also suggest different parameters.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then reading
-from it as if it was a plain file. Well written V4L2 applications should
-always ensure they really get what they want, requesting reasonable
-parameters and then checking if the actual parameters are suitable.
-
-To query the current raw VBI capture parameters applications set the
-``type`` field of a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VBI_CAPTURE`` or ``V4L2_BUF_TYPE_VBI_OUTPUT``, and call
-the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
-structure. Drivers fill the struct
-:c:type:`v4l2_vbi_format` ``vbi`` member of the
-``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_vbi_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers return an ``EINVAL`` error
-code only when the given parameters are ambiguous, otherwise they modify
-the parameters according to the hardware capabilities and return the
-actual parameters. When the driver allocates resources at this point, it
-may return an ``EBUSY`` error code to indicate the returned parameters are
-valid but the required resources are currently not available. That may
-happen for instance when the video and VBI areas to capture would
-overlap, or when the driver supports multiple opens and another process

-
-	An application can set the first or second ``count`` value to zero
-	if no data is required from the respective field; ``count``\ [1]

-    * - ``V4L2_VBI_INTERLACED``
-      - 0x0002
-      - By default the two field images will be passed sequentially; all

-	(compare :ref:`field-order` ``V4L2_FIELD_SEQ_TB`` and

-	may be necessary when the hardware has been programmed to capture
-	or output interlaced video images and is unable to separate the
-	fields for VBI capturing at the same time. For simplicity setting
-	this flag implies that both ``count`` values are equal and

-Remember the VBI image format depends on the selected video standard,

-current standard first. Attempts to read or write data ahead of format
-negotiation, or after switching the video standard which may invalidate
-the negotiated VBI parameters, should be refused by the driver. A format
-change during active I/O is not permitted.
-
-
-Reading and writing VBI images
-==============================
-
-To assure synchronization with the field number and easier
-implementation, the smallest unit of data passed at a time is one frame,
-consisting of two fields of VBI images immediately following in memory.
-
-The total size of a frame computes as follows:
-
-
-.. code-block:: c
-
-    (count[0] + count[1]) * samples_per_line * sample size in bytes
-
-The sample size is most likely always one byte, applications must check
-the ``sample_format`` field though, to function properly with other
-drivers.
-
-A VBI device may support :ref:`read/write <rw>` and/or streaming
-(:ref:`memory mapping <mmap>` or :ref:`user pointer <userp>`) I/O.
-The latter bears the possibility of synchronizing video and VBI data by
-using buffer timestamps.
-
-Remember the :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` ioctl and the
-first :ref:`read() <func-read>`, :ref:`write() <func-write>` and
-:ref:`select() <func-select>` call can be resource allocation
-points returning an ``EBUSY`` error code if the required hardware resources
-are temporarily unavailable, for example the device is already in use by
-another process.
-
-.. [#f1]
-   ASK: Amplitude-Shift Keying. A high signal level represents a '1'
-   bit, a low level a '0' bit.
-
-.. [#f2]
-   A few devices may be unable to sample VBI data at all but can extend
-   the video capture window to the VBI region.
-
-.. [#f3]
-   Most VBI services transmit on both fields, but some have different
-   semantics depending on the field number. These cannot be reliable
-   decoded or encoded when ``V4L2_VBI_UNSYNC`` is set.

-RDS Interface
-*************
-
-The Radio Data System transmits supplementary information in binary
-format, for example the station name or travel information, on an
-inaudible audio subcarrier of a radio program. This interface is aimed
-at devices capable of receiving and/or transmitting RDS information.
-
-For more information see the core RDS standard :ref:`iec62106` and the
-RBDS standard :ref:`nrsc4`.
-
-.. note::
-
-   Note that the RBDS standard as is used in the USA is almost
-   identical to the RDS standard. Any RDS decoder/encoder can also handle
-   RBDS. Only some of the fields have slightly different meanings. See the
-   RBDS standard for more information.
-
-The RBDS standard also specifies support for MMBS (Modified Mobile
-Search). This is a proprietary format which seems to be discontinued.
-The RDS interface does not support this format. Should support for MMBS
-(or the so-called 'E blocks' in general) be needed, then please contact
-the linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the RDS capturing API set the
-``V4L2_CAP_RDS_CAPTURE`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. Any tuner that
-supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
-``capability`` field of struct :c:type:`v4l2_tuner`. If the
-driver only passes RDS blocks without interpreting the data the
-``V4L2_TUNER_CAP_RDS_BLOCK_IO`` flag has to be set, see
-:ref:`Reading RDS data <reading-rds-data>`. For future use the flag
-``V4L2_TUNER_CAP_RDS_CONTROLS`` has also been defined. However, a driver
-for a radio tuner with this capability does not yet exist, so if you are
-planning to write such a driver you should discuss this on the
-linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-Whether an RDS signal is present can be detected by looking at the
-``rxsubchans`` field of struct :c:type:`v4l2_tuner`: the
-``V4L2_TUNER_SUB_RDS`` will be set if RDS data was detected.
-
-Devices supporting the RDS output API set the ``V4L2_CAP_RDS_OUTPUT``
-flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. Any modulator that
-supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
-``capability`` field of struct
-:c:type:`v4l2_modulator`. In order to enable the RDS
-transmission one must set the ``V4L2_TUNER_SUB_RDS`` bit in the
-``txsubchans`` field of struct
-:c:type:`v4l2_modulator`. If the driver only passes RDS
-blocks without interpreting the data the ``V4L2_TUNER_CAP_RDS_BLOCK_IO``
-flag has to be set. If the tuner is capable of handling RDS entities
-like program identification codes and radio text, the flag
-``V4L2_TUNER_CAP_RDS_CONTROLS`` should be set, see
-:ref:`Writing RDS data <writing-rds-data>` and
-:ref:`FM Transmitter Control Reference <fm-tx-controls>`.

-**************************************
-Software Defined Radio Interface (SDR)
-**************************************
-
-SDR is an abbreviation of Software Defined Radio, the radio device which
-uses application software for modulation or demodulation. This interface
-is intended for controlling and data streaming of such devices.
-
-SDR devices are accessed through character device special files named
-``/dev/swradio0`` to ``/dev/swradio255`` with major number 81 and
-dynamically allocated minor numbers 0 to 255.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the SDR receiver interface set the
-``V4L2_CAP_SDR_CAPTURE`` and ``V4L2_CAP_TUNER`` flag in the
-``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
-device has an Analog to Digital Converter (ADC), which is a mandatory
-element for the SDR receiver.
-
-Devices supporting the SDR transmitter interface set the
-``V4L2_CAP_SDR_OUTPUT`` and ``V4L2_CAP_MODULATOR`` flag in the
-``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
-device has an Digital to Analog Converter (DAC), which is a mandatory
-element for the SDR transmitter.
-
-At least one of the read/write, streaming or asynchronous I/O methods
-must be supported.
-
-
-Supplemental Functions
-======================
-
-SDR devices can support :ref:`controls <control>`, and must support
-the :ref:`tuner` ioctls. Tuner ioctls are used for setting the
-ADC/DAC sampling rate (sampling frequency) and the possible radio
-frequency (RF).
-
-The ``V4L2_TUNER_SDR`` tuner type is used for setting SDR device ADC/DAC
-frequency, and the ``V4L2_TUNER_RF`` tuner type is used for setting
-radio frequency. The tuner index of the RF tuner (if any) must always
-follow the SDR tuner index. Normally the SDR tuner is #0 and the RF
-tuner is #1.
-
-The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl is
-not supported.
-
-
-Data Format Negotiation
-=======================
-
-The SDR device uses the :ref:`format` ioctls to select the
-capture and output format. Both the sampling resolution and the data
-streaming format are bound to that selectable format. In addition to the
-basic :ref:`format` ioctls, the
-:ref:`VIDIOC_ENUM_FMT` ioctl must be supported as
-well.
-
-To use the :ref:`format` ioctls applications set the ``type``
-field of a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_SDR_CAPTURE`` or ``V4L2_BUF_TYPE_SDR_OUTPUT`` and use
-the struct :c:type:`v4l2_sdr_format` ``sdr`` member
-of the ``fmt`` union as needed per the desired operation. Currently
-there is two fields, ``pixelformat`` and ``buffersize``, of struct
-struct :c:type:`v4l2_sdr_format` which are used.
-Content of the ``pixelformat`` is V4L2 FourCC code of the data format.
-The ``buffersize`` field is maximum buffer size in bytes required for
-data transfer, set by the driver in order to inform application.

-*************************
-Sliced VBI Data Interface
-*************************
-
-VBI stands for Vertical Blanking Interval, a gap in the sequence of
-lines of an analog video signal. During VBI no picture information is
-transmitted, allowing some time while the electron beam of a cathode ray
-tube TV returns to the top of the screen.
-
-Sliced VBI devices use hardware to demodulate data transmitted in the
-VBI. V4L2 drivers shall *not* do this by software, see also the
-:ref:`raw VBI interface <raw-vbi>`. The data is passed as short
-packets of fixed size, covering one scan line each. The number of
-packets per video frame is variable.
-
-Sliced VBI capture and output devices are accessed through the same
-character special files as raw VBI devices. When a driver supports both
-interfaces, the default function of a ``/dev/vbi`` device is *raw* VBI
-capturing or output, and the sliced VBI function is only available after
-calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl as defined
-below. Likewise a ``/dev/video`` device may support the sliced VBI API,
-however the default function here is video capturing or output.
-Different file descriptors must be used to pass raw and sliced VBI data
-simultaneously, if this is supported by the driver.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the sliced VBI capturing or output API set the
-``V4L2_CAP_SLICED_VBI_CAPTURE`` or ``V4L2_CAP_SLICED_VBI_OUTPUT`` flag

-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
-read/write, streaming or asynchronous :ref:`I/O methods <io>` must be
-supported. Sliced VBI devices may have a tuner or modulator.
-
-
-Supplemental Functions
-======================
-
-Sliced VBI devices shall support :ref:`video input or output <video>`
-and :ref:`tuner or modulator <tuner>` ioctls if they have these
-capabilities, and they may support :ref:`control` ioctls.

-lines the hardware can capture or output per frame, or the number of
-services it can identify on a given line are limited. For example on PAL
-line 16 the hardware may be able to look for a VPS or Teletext signal,
-but not both at the same time.
-
-To determine the currently selected services applications set the
-``type`` field of struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` or
-``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``, and the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl fills the ``fmt.sliced``
-member, a struct
-:c:type:`v4l2_sliced_vbi_format`.
-
-Applications can request different parameters by initializing or
-modifying the ``fmt.sliced`` member and calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with a pointer to the
-struct :c:type:`v4l2_format` structure.
-
-The sliced VBI API is more complicated than the raw VBI API because the
-hardware must be told which VBI service to expect on each scan line. Not
-all services may be supported by the hardware on all lines (this is
-especially true for VBI output where Teletext is often unsupported and
-other services can only be inserted in one specific line). In many
-cases, however, it is sufficient to just set the ``service_set`` field
-to the required services and let the driver fill the ``service_lines``
-array according to hardware capabilities. Only if more precise control
-is needed should the programmer set the ``service_lines`` array
-explicitly.
-
-The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl modifies the parameters
-according to hardware capabilities. When the driver allocates resources
-at this point, it may return an ``EBUSY`` error code if the required
-resources are temporarily unavailable. Other resource allocation points
-which may return ``EBUSY`` can be the
-:ref:`VIDIOC_STREAMON` ioctl and the first
-:ref:`read() <func-read>`, :ref:`write() <func-write>` and
-:ref:`select() <func-select>` call.

-Drivers may return an ``EINVAL`` error code when applications attempt to

-of struct :c:type:`v4l2_sliced_vbi_data` structures with one or
-more elements and a total size not exceeding ``io_size`` bytes. Likewise
-in streaming I/O mode one buffer of ``io_size`` bytes must contain data
-of one video frame. The ``id`` of unused
-struct :c:type:`v4l2_sliced_vbi_data` elements must be zero.

-
-
-Packets are always passed in ascending line number order, without
-duplicate line numbers. The :ref:`write() <func-write>` function and
-the :ref:`VIDIOC_QBUF` ioctl must return an ``EINVAL``
-error code when applications violate this rule. They must also return an
-EINVAL error code when applications pass an incorrect field or line

-been negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` or
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When the line numbers are
-unknown the driver must pass the packets in transmitted order. The
-driver can insert empty packets with ``id`` set to zero anywhere in the
-packet array.
-
-To assure synchronization and to distinguish from frame dropping, when a
-captured frame does not carry any of the requested data services drivers
-must pass one or more empty packets. When an application fails to pass
-VBI data in time for output, the driver must output the last VPS and WSS
-packet again, and disable the output of Closed Caption and Teletext
-data, or output data which is ignored by Closed Caption and Teletext
-decoders.
-
-A sliced VBI device may support :ref:`read/write <rw>` and/or
-streaming (:ref:`memory mapping <mmap>` and/or
-:ref:`user pointer <userp>`) I/O. The latter bears the possibility of
-synchronizing video and VBI data by using buffer timestamps.
-
-
-Sliced VBI Data in MPEG Streams
-===============================
-
-If a device can produce an MPEG output stream, it may be capable of
-providing
-:ref:`negotiated sliced VBI services <sliced-vbi-format-negotitation>`
-as data embedded in the MPEG stream. Users or applications control this
-sliced VBI data insertion with the
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control.
-
-If the driver does not provide the
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control, or only allows that control to be set to
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`,
-then the device cannot embed sliced VBI data in the MPEG stream.
-
-The
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control does not implicitly set the device driver to capture nor cease
-capturing sliced VBI data. The control only indicates to embed sliced
-VBI data in the MPEG stream, if an application has negotiated sliced VBI
-service be captured.
-
-It may also be the case that a device can embed sliced VBI data in only
-certain types of MPEG streams: for example in an MPEG-2 PS but not an
-MPEG-2 TS. In this situation, if sliced VBI data insertion is requested,
-the sliced VBI data will be embedded in MPEG stream types when
-supported, and silently omitted from MPEG stream types where sliced VBI
-data insertion is not supported by the device.
-
-The following subsections specify the format of the embedded sliced VBI
-data.
-
-
-MPEG Stream Embedded, Sliced VBI Data Format: NONE
---------------------------------------------------
-
-The
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`
-embedded sliced VBI format shall be interpreted by drivers as a control
-to cease embedding sliced VBI data in MPEG streams. Neither the device
-nor driver shall insert "empty" embedded sliced VBI data packets in the
-MPEG stream when this format is set. No MPEG stream data structures are
-specified for this format.
-
-
-MPEG Stream Embedded, Sliced VBI Data Format: IVTV
---------------------------------------------------
-
-The
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
-embedded sliced VBI format, when supported, indicates to the driver to
-embed up to 36 lines of sliced VBI data per frame in an MPEG-2 *Private
-Stream 1 PES* packet encapsulated in an MPEG-2 *Program Pack* in the
-MPEG stream.
-
-*Historical context*: This format specification originates from a
-custom, embedded, sliced VBI data format used by the ``ivtv`` driver.
-This format has already been informally specified in the kernel sources
-in the file ``Documentation/media/v4l-drivers/cx2341x.rst`` . The
-maximum size of the payload and other aspects of this format are driven
-by the CX23415 MPEG decoder's capabilities and limitations with respect
-to extracting, decoding, and displaying sliced VBI data embedded within
-an MPEG stream.
-
-This format's use is *not* exclusive to the ``ivtv`` driver *nor*
-exclusive to CX2341x devices, as the sliced VBI data packet insertion
-into the MPEG stream is implemented in driver software. At least the
-``cx18`` driver provides sliced VBI data insertion into an MPEG-2 PS in
-this format as well.
-
-The following definitions specify the payload of the MPEG-2 *Private
-Stream 1 PES* packets that contain sliced VBI data when
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
-is set. (The MPEG-2 *Private Stream 1 PES* packet header and
-encapsulating MPEG-2 *Program Pack* header are not detailed here. Please
-refer to the MPEG-2 specifications for details on those packet headers.)
-
-The payload of the MPEG-2 *Private Stream 1 PES* packets that contain
-sliced VBI data is specified by struct
-:c:type:`v4l2_mpeg_vbi_fmt_ivtv`. The
-payload is variable length, depending on the actual number of lines of
-sliced VBI data present in a video frame. The payload may be padded at
-the end with unspecified fill bytes to align the end of the payload to a
-4-byte boundary. The payload shall never exceed 1552 bytes (2 fields
-with 18 lines/field with 43 bytes of data/line and a 4 byte magic
-number).

-********************
-Sub-device Interface
-********************
-
-The complex nature of V4L2 devices, where hardware is often made of
-several integrated circuits that need to interact with each other in a
-controlled way, leads to complex V4L2 drivers. The drivers usually
-reflect the hardware model in software, and model the different hardware
-components as software blocks called sub-devices.
-
-V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
-implements the media device API, they will automatically inherit from
-media entities. Applications will be able to enumerate the sub-devices
-and discover the hardware topology using the media entities, pads and
-links enumeration API.
-
-In addition to make sub-devices discoverable, drivers can also choose to
-make them directly configurable by applications. When both the
-sub-device driver and the V4L2 device driver support this, sub-devices
-will feature a character device node on which ioctls can be called to
-
--  query, read and write sub-devices controls
-
--  subscribe and unsubscribe to events and retrieve them
-
--  negotiate image formats on individual pads
-
-Sub-device character device nodes, conventionally named
-``/dev/v4l-subdev*``, use major number 81.
-
-
-Controls
-========
-
-Most V4L2 controls are implemented by sub-device hardware. Drivers
-usually merge all controls and expose them through video device nodes.
-Applications can control all sub-devices through a single interface.
-
-Complex devices sometimes implement the same control in different pieces
-of hardware. This situation is common in embedded platforms, where both
-sensors and image processing hardware implement identical functions,
-such as contrast adjustment, white balance or faulty pixels correction.
-As the V4L2 controls API doesn't support several identical controls in a
-single device, all but one of the identical controls are hidden.
-
-Applications can access those hidden controls through the sub-device
-node with the V4L2 control API described in :ref:`control`. The ioctls
-behave identically as when issued on V4L2 device nodes, with the
-exception that they deal only with controls implemented in the
-sub-device.
-
-Depending on the driver, those controls might also be exposed through
-one (or several) V4L2 device nodes.
-
-
-Events
-======
-
-V4L2 sub-devices can notify applications of events as described in
-:ref:`event`. The API behaves identically as when used on V4L2 device
-nodes, with the exception that it only deals with events generated by
-the sub-device. Depending on the driver, those events might also be
-reported on one (or several) V4L2 device nodes.
-
-
-.. _pad-level-formats:
-
-Pad-level Formats
-=================
-
-.. warning::
-
-    Pad-level formats are only applicable to very complex devices that
-    need to expose low-level format configuration to user space. Generic
-    V4L2 applications do *not* need to use the API described in this
-    section.
-
-.. note::
-
-    For the purpose of this section, the term *format* means the
-    combination of media bus data format, frame width and frame height.
-
-Image formats are typically negotiated on video capture and output
-devices using the format and
-:ref:`selection <VIDIOC_SUBDEV_G_SELECTION>` ioctls. The driver is
-responsible for configuring every block in the video pipeline according
-to the requested format at the pipeline input and/or output.
-
-For complex devices, such as often found in embedded systems, identical
-image sizes at the output of a pipeline can be achieved using different
-hardware configurations. One such example is shown on
-:ref:`pipeline-scaling`, where image scaling can be performed on both
-the video sensor and the host image processing hardware.
-
-
-.. _pipeline-scaling:
-
-.. kernel-figure:: pipeline.dot
-    :alt:   pipeline.dot
-    :align: center
-
-    Image Format Negotiation on Pipelines
-
-    High quality and high speed pipeline configuration
-
-
-
-The sensor scaler is usually of less quality than the host scaler, but
-scaling on the sensor is required to achieve higher frame rates.
-Depending on the use case (quality vs. speed), the pipeline must be
-configured differently. Applications need to configure the formats at
-every point in the pipeline explicitly.
-
-Drivers that implement the :ref:`media API <media-controller-intro>`
-can expose pad-level image format configuration to applications. When
-they do, applications can use the
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls. to
-negotiate formats on a per-pad basis.
-
-Applications are responsible for configuring coherent parameters on the
-whole pipeline and making sure that connected pads have compatible
-formats. The pipeline is checked for formats mismatch at
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` time, and an ``EPIPE`` error
-code is then returned if the configuration is invalid.
-
-Pad-level image format configuration support can be tested by calling
-the :ref:`VIDIOC_SUBDEV_G_FMT` ioctl on pad
-0. If the driver returns an ``EINVAL`` error code pad-level format
-configuration is not supported by the sub-device.
-
-
-Format Negotiation
-------------------
-
-Acceptable formats on pads can (and usually do) depend on a number of
-external parameters, such as formats on other pads, active links, or
-even controls. Finding a combination of formats on all pads in a video
-pipeline, acceptable to both application and driver, can't rely on
-formats enumeration only. A format negotiation mechanism is required.
-
-Central to the format negotiation mechanism are the get/set format
-operations. When called with the ``which`` argument set to
-:ref:`V4L2_SUBDEV_FORMAT_TRY <VIDIOC_SUBDEV_G_FMT>`, the
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls operate on
-a set of formats parameters that are not connected to the hardware
-configuration. Modifying those 'try' formats leaves the device state
-untouched (this applies to both the software state stored in the driver
-and the hardware state stored in the device itself).
-
-While not kept as part of the device state, try formats are stored in
-the sub-device file handles. A
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` call will return
-the last try format set *on the same sub-device file handle*. Several
-applications querying the same sub-device at the same time will thus not
-interact with each other.
-
-To find out whether a particular format is supported by the device,
-applications use the
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl. Drivers
-verify and, if needed, change the requested ``format`` based on device
-requirements and return the possibly modified value. Applications can
-then choose to try a different format or accept the returned value and
-continue.
-
-Formats returned by the driver during a negotiation iteration are
-guaranteed to be supported by the device. In particular, drivers
-guarantee that a returned format will not be further changed if passed
-to an :ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` call as-is
-(as long as external parameters, such as formats on other pads or links'
-configuration are not changed).
-
-Drivers automatically propagate formats inside sub-devices. When a try
-or active format is set on a pad, corresponding formats on other pads of
-the same sub-device can be modified by the driver. Drivers are free to
-modify formats as required by the device. However, they should comply
-with the following rules when possible:
-
--  Formats should be propagated from sink pads to source pads. Modifying
-   a format on a source pad should not modify the format on any sink
-   pad.
-
--  Sub-devices that scale frames using variable scaling factors should
-   reset the scale factors to default values when sink pads formats are
-   modified. If the 1:1 scaling ratio is supported, this means that
-   source pads formats should be reset to the sink pads formats.
-
-Formats are not propagated across links, as that would involve
-propagating them from one sub-device file handle to another.
-Applications must then take care to configure both ends of every link
-explicitly with compatible formats. Identical formats on the two ends of
-a link are guaranteed to be compatible. Drivers are free to accept
-different formats matching device requirements as being compatible.

-
-1. Initial state. The sensor source pad format is set to its native 3MP
-   size and V4L2_MBUS_FMT_SGRBG8_1X8 media bus code. Formats on the
-   host frontend and scaler sink and source pads have the default
-   values, as well as the compose rectangle on the scaler's sink pad.
-
-2. The application configures the frontend sink pad format's size to
-   2048x1536 and its media bus code to V4L2_MBUS_FMT_SGRBG_1X8. The
-   driver propagates the format to the frontend source pad.
-
-3. The application configures the scaler sink pad format's size to
-   2046x1534 and the media bus code to V4L2_MBUS_FMT_SGRBG_1X8 to
-   match the frontend source size and media bus code. The media bus code
-   on the sink pad is set to V4L2_MBUS_FMT_SGRBG_1X8. The driver
-   propagates the size to the compose selection rectangle on the
-   scaler's sink pad, and the format to the scaler source pad.
-
-4. The application configures the size of the compose selection
-   rectangle of the scaler's sink pad 1280x960. The driver propagates
-   the size to the scaler's source pad format.
-
-When satisfied with the try results, applications can set the active
-formats by setting the ``which`` argument to
-``V4L2_SUBDEV_FORMAT_ACTIVE``. Active formats are changed exactly as try
-formats by drivers. To avoid modifying the hardware state during format
-negotiation, applications should negotiate try formats first and then
-modify the active settings using the try formats returned during the
-last negotiation iteration. This guarantees that the active format will
-be applied as-is by the driver without being modified.
-
-
-.. _v4l2-subdev-selections:
-
-Selections: cropping, scaling and composition
----------------------------------------------
-
-Many sub-devices support cropping frames on their input or output pads
-(or possible even on both). Cropping is used to select the area of
-interest in an image, typically on an image sensor or a video decoder.
-It can also be used as part of digital zoom implementations to select
-the area of the image that will be scaled up.
-
-Crop settings are defined by a crop rectangle and represented in a
-struct :c:type:`v4l2_rect` by the coordinates of the top
-left corner and the rectangle size. Both the coordinates and sizes are
-expressed in pixels.
-
-As for pad formats, drivers store try and active rectangles for the
-selection targets :ref:`v4l2-selections-common`.
-
-On sink pads, cropping is applied relative to the current pad format.
-The pad format represents the image size as received by the sub-device
-from the previous block in the pipeline, and the crop rectangle
-represents the sub-image that will be transmitted further inside the
-sub-device for processing.
-
-The scaling operation changes the size of the image by scaling it to new
-dimensions. The scaling ratio isn't specified explicitly, but is implied
-from the original and scaled image sizes. Both sizes are represented by
-struct :c:type:`v4l2_rect`.
-
-Scaling support is optional. When supported by a subdev, the crop
-rectangle on the subdev's sink pad is scaled to the size configured
-using the
-:ref:`VIDIOC_SUBDEV_S_SELECTION <VIDIOC_SUBDEV_G_SELECTION>` IOCTL
-using ``V4L2_SEL_TGT_COMPOSE`` selection target on the same pad. If the
-subdev supports scaling but not composing, the top and left values are
-not used and must always be set to zero.
-
-On source pads, cropping is similar to sink pads, with the exception
-that the source size from which the cropping is performed, is the
-COMPOSE rectangle on the sink pad. In both sink and source pads, the
-crop rectangle must be entirely contained inside the source image size
-for the crop operation.
-
-The drivers should always use the closest possible rectangle the user
-requests on all selection targets, unless specifically told otherwise.
-``V4L2_SEL_FLAG_GE`` and ``V4L2_SEL_FLAG_LE`` flags may be used to round
-the image size either up or down. :ref:`v4l2-selection-flags`
-
-
-Types of selection targets
---------------------------
-
-
-Actual targets
-^^^^^^^^^^^^^^
-
-Actual targets (without a postfix) reflect the actual hardware
-configuration at any point of time. There is a BOUNDS target
-corresponding to every actual target.
-
-
-BOUNDS targets
-^^^^^^^^^^^^^^
-
-BOUNDS targets is the smallest rectangle that contains all valid actual
-rectangles. It may not be possible to set the actual rectangle as large
-as the BOUNDS rectangle, however. This may be because e.g. a sensor's
-pixel array is not rectangular but cross-shaped or round. The maximum
-size may also be smaller than the BOUNDS rectangle.
-
-
-Order of configuration and format propagation
----------------------------------------------
-
-Inside subdevs, the order of image processing steps will always be from
-the sink pad towards the source pad. This is also reflected in the order
-in which the configuration must be performed by the user: the changes
-made will be propagated to any subsequent stages. If this behaviour is
-not desired, the user must set ``V4L2_SEL_FLAG_KEEP_CONFIG`` flag. This
-flag causes no propagation of the changes are allowed in any
-circumstances. This may also cause the accessed rectangle to be adjusted
-by the driver, depending on the properties of the underlying hardware.
-
-The coordinates to a step always refer to the actual size of the
-previous step. The exception to this rule is the sink compose
-rectangle, which refers to the sink compose bounds rectangle --- if it
-is supported by the hardware.
-
-1. Sink pad format. The user configures the sink pad format. This format
-   defines the parameters of the image the entity receives through the
-   pad for further processing.
-
-2. Sink pad actual crop selection. The sink pad crop defines the crop
-   performed to the sink pad format.
-
-3. Sink pad actual compose selection. The size of the sink pad compose
-   rectangle defines the scaling ratio compared to the size of the sink
-   pad crop rectangle. The location of the compose rectangle specifies
-   the location of the actual sink compose rectangle in the sink compose
-   bounds rectangle.
-
-4. Source pad actual crop selection. Crop on the source pad defines crop
-   performed to the image in the sink compose bounds rectangle.
-
-5. Source pad format. The source pad format defines the output pixel
-   format of the subdev, as well as the other parameters with the
-   exception of the image width and height. Width and height are defined
-   by the size of the source pad actual crop selection.
-
-Accessing any of the above rectangles not supported by the subdev will
-return ``EINVAL``. Any rectangle referring to a previous unsupported
-rectangle coordinates will instead refer to the previous supported
-rectangle. For example, if sink crop is not supported, the compose
-selection will refer to the sink pad format dimensions instead.

-
-    **Figure 4.5. Image processing in subdevs: simple crop example**
-
-In the above example, the subdev supports cropping on its sink pad. To
-configure it, the user sets the media bus format on the subdev's sink
-pad. Now the actual crop rectangle can be set on the sink pad --- the
-location and size of this rectangle reflect the location and size of a
-rectangle to be cropped from the sink format. The size of the sink crop
-rectangle will also be the size of the format of the subdev's source
-pad.

-In this example, the subdev is capable of first cropping, then scaling
-and finally cropping for two source pads individually from the resulting
-scaled image. The location of the scaled image in the cropped image is
-ignored in sink compose target. Both of the locations of the source crop
-rectangles refer to the sink scaling rectangle, independently cropping

-
-The subdev driver supports two sink pads and two source pads. The images
-from both of the sink pads are individually cropped, then scaled and
-further composed on the composition bounds rectangle. From that, two
-independent streams are cropped and sent out of the subdev from the
-source pads.

-Touch Devices
-*************
-
-Touch devices are accessed through character device special files named
-``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
-dynamically allocated minor numbers 0 to 255.
-
-Overview
-========
-
-Sensors may be Optical, or Projected Capacitive touch (PCT).
-
-Processing is required to analyse the raw data and produce input events. In
-some systems, this may be performed on the ASIC and the raw data is purely a
-side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
-analogue front end device which delivers touch data at high rate, and any touch
-processing must be done on the host.
-
-For capacitive touch sensing, the touchscreen is composed of an array of
-horizontal and vertical conductors (alternatively called rows/columns, X/Y
-lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
-conductors cross. Alternatively, Self Capacitance measures the signal from each
-column and row independently.
-
-A touch input may be determined by comparing the raw capacitance measurement to
-a no-touch reference (or "baseline") measurement:
-
-Delta = Raw - Reference
-
-The reference measurement takes account of variations in the capacitance across
-the touch sensor matrix, for example manufacturing irregularities,
-environmental or edge effects.
-
-Querying Capabilities
-=====================
-
-Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
-and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-At least one of the read/write or streaming I/O methods must be
-supported.
-
-The formats supported by touch devices are documented in
-:ref:`Touch Formats <tch-formats>`.
-
-Data Format Negotiation
-=======================
-
-A touch device may support any I/O method.

-Differences between V4L and V4L2
-********************************
-
-The Video For Linux API was first introduced in Linux 2.1 to unify and
-replace various TV and radio device related interfaces, developed
-independently by driver writers in prior years. Starting with Linux 2.5
-the much improved V4L2 API replaces the V4L API. The support for the old
-V4L calls were removed from Kernel, but the library :ref:`libv4l`
-supports the conversion of a V4L API system call into a V4L2 one.
-
-
-Opening and Closing Devices
-===========================
-
-For compatibility reasons the character device file names recommended
-for V4L2 video capture, overlay, radio and raw vbi capture devices did
-not change from those used by V4L. They are listed in :ref:`devices`
-and below in :ref:`v4l-dev`.
-
-The teletext devices (minor range 192-223) have been removed in V4L2 and
-no longer exist. There is no hardware available anymore for handling
-pure teletext. Instead raw or sliced VBI is used.
-
-The V4L ``videodev`` module automatically assigns minor numbers to
-drivers in load order, depending on the registered device type. We
-recommend that V4L2 drivers by default register devices with the same
-numbers, but the system administrator can assign arbitrary minor numbers
-using driver module options. The major device number remains 81.

-
-V4L prohibits (or used to prohibit) multiple opens of a device file.
-V4L2 drivers *may* support multiple opens, see :ref:`open` for details
-and consequences.
-
-V4L drivers respond to V4L2 ioctls with an ``EINVAL`` error code.
-
-
-Querying Capabilities
-=====================
-
-The V4L ``VIDIOCGCAP`` ioctl is equivalent to V4L2's
-:ref:`VIDIOC_QUERYCAP`.
-
-The ``name`` field in struct ``video_capability`` became
-``card`` in struct :c:type:`v4l2_capability`, ``type``
-was replaced by ``capabilities``. Note V4L2 does not distinguish between
-device types like this, better think of basic video input, video output
-and radio devices supporting a set of related functions like video
-capturing, video overlay and VBI capturing. See :ref:`open` for an
-introduction.

-    * - ``VID_TYPE_SCALES``
-      - ``-``
-      - This flag indicates if the hardware can scale images. The V4L2 API

-      - ``-``
-      - Applications can call the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>`

-    * - ``VID_TYPE_MPEG_DECODER``
-      - ``-``

-      - See above.
-
-
-The ``audios`` field was replaced by ``capabilities`` flag
-``V4L2_CAP_AUDIO``, indicating *if* the device has any audio inputs or
-outputs. To determine their number applications can enumerate audio
-inputs with the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl. The
-audio ioctls are described in :ref:`audio`.
-
-The ``maxwidth``, ``maxheight``, ``minwidth`` and ``minheight`` fields
-were removed. Calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl with the desired
-dimensions returns the closest size possible, taking into account the
-current video standard, cropping and scaling limitations.
-
-
-Video Sources
-=============
-
-V4L provides the ``VIDIOCGCHAN`` and ``VIDIOCSCHAN`` ioctl using struct
-``video_channel`` to enumerate the video inputs of a V4L
-device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_ENUMINPUT`,
-:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` using struct
-:c:type:`v4l2_input` as discussed in :ref:`video`.
-
-The ``channel`` field counting inputs was renamed to ``index``, the
-video input types were renamed as follows:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct ``video_channel`` ``type``
-      - struct :c:type:`v4l2_input` ``type``
-    * - ``VIDEO_TYPE_TV``
-      - ``V4L2_INPUT_TYPE_TUNER``
-    * - ``VIDEO_TYPE_CAMERA``
-      - ``V4L2_INPUT_TYPE_CAMERA``
-
-
-Unlike the ``tuners`` field expressing the number of tuners of this
-input, V4L2 assumes each video input is connected to at most one tuner.
-However a tuner can have more than one input, i. e. RF connectors, and a
-device can have multiple tuners. The index number of the tuner
-associated with the input, if any, is stored in field ``tuner`` of
-struct :c:type:`v4l2_input`. Enumeration of tuners is
-discussed in :ref:`tuner`.
-
-The redundant ``VIDEO_VC_TUNER`` flag was dropped. Video inputs
-associated with a tuner are of type ``V4L2_INPUT_TYPE_TUNER``. The
-``VIDEO_VC_AUDIO`` flag was replaced by the ``audioset`` field. V4L2
-considers devices with up to 32 audio inputs. Each set bit in the
-``audioset`` field represents one audio input this video input combines
-with. For information about audio inputs and how to switch between them
-see :ref:`audio`.
-
-The ``norm`` field describing the supported video standards was replaced
-by ``std``. The V4L specification mentions a flag ``VIDEO_VC_NORM``
-indicating whether the standard can be changed. This flag was a later
-addition together with the ``norm`` field and has been removed in the
-meantime. V4L2 has a similar, albeit more comprehensive approach to
-video standards, see :ref:`standard` for more information.
-
-
-Tuning
-======
-
-The V4L ``VIDIOCGTUNER`` and ``VIDIOCSTUNER`` ioctl and struct
-``video_tuner`` can be used to enumerate the tuners of a
-V4L TV or radio device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
-:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` using struct
-:c:type:`v4l2_tuner`. Tuners are covered in :ref:`tuner`.
-
-The ``tuner`` field counting tuners was renamed to ``index``. The fields
-``name``, ``rangelow`` and ``rangehigh`` remained unchanged.
-
-The ``VIDEO_TUNER_PAL``, ``VIDEO_TUNER_NTSC`` and ``VIDEO_TUNER_SECAM``
-flags indicating the supported video standards were dropped. This
-information is now contained in the associated struct
-:c:type:`v4l2_input`. No replacement exists for the
-``VIDEO_TUNER_NORM`` flag indicating whether the video standard can be
-switched. The ``mode`` field to select a different video standard was
-replaced by a whole new set of ioctls and structures described in
-:ref:`standard`. Due to its ubiquity it should be mentioned the BTTV
-driver supports several standards in addition to the regular
-``VIDEO_MODE_PAL`` (0), ``VIDEO_MODE_NTSC``, ``VIDEO_MODE_SECAM`` and
-``VIDEO_MODE_AUTO`` (3). Namely N/PAL Argentina, M/PAL, N/PAL, and NTSC
-Japan with numbers 3-6 (sic).
-
-The ``VIDEO_TUNER_STEREO_ON`` flag indicating stereo reception became
-``V4L2_TUNER_SUB_STEREO`` in field ``rxsubchans``. This field also
-permits the detection of monaural and bilingual audio, see the
-definition of struct :c:type:`v4l2_tuner` for details.
-Presently no replacement exists for the ``VIDEO_TUNER_RDS_ON`` and
-``VIDEO_TUNER_MBS_ON`` flags.
-
-The ``VIDEO_TUNER_LOW`` flag was renamed to ``V4L2_TUNER_CAP_LOW`` in
-the struct :c:type:`v4l2_tuner` ``capability`` field.
-
-The ``VIDIOCGFREQ`` and ``VIDIOCSFREQ`` ioctl to change the tuner
-frequency where renamed to
-:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`. They take a pointer
-to a struct :c:type:`v4l2_frequency` instead of an
-unsigned long integer.

-Image Properties
-================
-
-V4L2 has no equivalent of the ``VIDIOCGPICT`` and ``VIDIOCSPICT`` ioctl
-and struct ``video_picture``. The following fields where
-replaced by V4L2 controls accessible with the
-:ref:`VIDIOC_QUERYCTRL`,
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct ``video_picture``
-      - V4L2 Control ID
-    * - ``brightness``
-      - ``V4L2_CID_BRIGHTNESS``
-    * - ``hue``
-      - ``V4L2_CID_HUE``
-    * - ``colour``
-      - ``V4L2_CID_SATURATION``
-    * - ``contrast``
-      - ``V4L2_CID_CONTRAST``
-    * - ``whiteness``
-      - ``V4L2_CID_WHITENESS``
-
-
-The V4L picture controls are assumed to range from 0 to 65535 with no
-particular reset value. The V4L2 API permits arbitrary limits and
-defaults which can be queried with the
-:ref:`VIDIOC_QUERYCTRL` ioctl. For general
-information about controls see :ref:`control`.
-
-The ``depth`` (average number of bits per pixel) of a video image is
-implied by the selected image format. V4L2 does not explicitly provide
-such information assuming applications recognizing the format are aware
-of the image depth and others need not know. The ``palette`` field moved
-into the struct :c:type:`v4l2_pix_format`:
-
-
-

-    * - ``VIDEO_PALETTE_YUV410P``
-      - :ref:`V4L2_PIX_FMT_YVU410 <V4L2-PIX-FMT-YVU410>`
-
-
-V4L2 image formats are defined in :ref:`pixfmt`. The image format can
-be selected with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Audio
-=====
-
-The ``VIDIOCGAUDIO`` and ``VIDIOCSAUDIO`` ioctl and struct
-``video_audio`` are used to enumerate the audio inputs
-of a V4L device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
-:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` using struct
-:c:type:`v4l2_audio` as discussed in :ref:`audio`.
-
-The ``audio`` "channel number" field counting audio inputs was renamed
-to ``index``.
-
-On ``VIDIOCSAUDIO`` the ``mode`` field selects *one* of the
-``VIDEO_SOUND_MONO``, ``VIDEO_SOUND_STEREO``, ``VIDEO_SOUND_LANG1`` or
-``VIDEO_SOUND_LANG2`` audio demodulation modes. When the current audio
-standard is BTSC ``VIDEO_SOUND_LANG2`` refers to SAP and
-``VIDEO_SOUND_LANG1`` is meaningless. Also undocumented in the V4L
-specification, there is no way to query the selected mode. On
-``VIDIOCGAUDIO`` the driver returns the *actually received* audio
-programmes in this field. In the V4L2 API this information is stored in
-the struct :c:type:`v4l2_tuner` ``rxsubchans`` and
-``audmode`` fields, respectively. See :ref:`tuner` for more
-information on tuners. Related to audio modes struct
-:c:type:`v4l2_audio` also reports if this is a mono or
-stereo input, regardless if the source is a tuner.
-
-The following fields where replaced by V4L2 controls accessible with the
-:ref:`VIDIOC_QUERYCTRL`,
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct ``video_audio``
-      - V4L2 Control ID
-    * - ``volume``
-      - ``V4L2_CID_AUDIO_VOLUME``
-    * - ``bass``
-      - ``V4L2_CID_AUDIO_BASS``
-    * - ``treble``
-      - ``V4L2_CID_AUDIO_TREBLE``
-    * - ``balance``
-      - ``V4L2_CID_AUDIO_BALANCE``
-
-
-To determine which of these controls are supported by a driver V4L
-provides the ``flags`` ``VIDEO_AUDIO_VOLUME``, ``VIDEO_AUDIO_BASS``,
-``VIDEO_AUDIO_TREBLE`` and ``VIDEO_AUDIO_BALANCE``. In the V4L2 API the
-:ref:`VIDIOC_QUERYCTRL` ioctl reports if the
-respective control is supported. Accordingly the ``VIDEO_AUDIO_MUTABLE``
-and ``VIDEO_AUDIO_MUTE`` flags where replaced by the boolean
-``V4L2_CID_AUDIO_MUTE`` control.
-
-All V4L2 controls have a ``step`` attribute replacing the struct
-``video_audio`` ``step`` field. The V4L audio controls
-are assumed to range from 0 to 65535 with no particular reset value. The
-V4L2 API permits arbitrary limits and defaults which can be queried with
-the :ref:`VIDIOC_QUERYCTRL` ioctl. For general
-information about controls see :ref:`control`.
-
-
-Frame Buffer Overlay
-====================
-
-The V4L2 ioctls equivalent to ``VIDIOCGFBUF`` and ``VIDIOCSFBUF`` are
-:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
-:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The ``base`` field of struct
-``video_buffer`` remained unchanged, except V4L2 defines
-a flag to indicate non-destructive overlays instead of a ``NULL``
-pointer. All other fields moved into the struct
-:c:type:`v4l2_pix_format` ``fmt`` substructure of
-struct :c:type:`v4l2_framebuffer`. The ``depth``
-field was replaced by ``pixelformat``. See :ref:`pixfmt-rgb` for a
-list of RGB formats and their respective color depths.
-
-Instead of the special ioctls ``VIDIOCGWIN`` and ``VIDIOCSWIN`` V4L2
-uses the general-purpose data format negotiation ioctls
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
-:c:type:`v4l2_format` as argument. Here the ``win`` member
-of the ``fmt`` union is used, a struct
-:c:type:`v4l2_window`.
-
-The ``x``, ``y``, ``width`` and ``height`` fields of struct
-``video_window`` moved into struct
-:c:type:`v4l2_rect` substructure ``w`` of struct
-:c:type:`v4l2_window`. The ``chromakey``, ``clips``, and
-``clipcount`` fields remained unchanged. Struct
-``video_clip`` was renamed to struct
-:c:type:`v4l2_clip`, also containing a struct
-:c:type:`v4l2_rect`, but the semantics are still the same.
-
-The ``VIDEO_WINDOW_INTERLACE`` flag was dropped. Instead applications
-must set the ``field`` field to ``V4L2_FIELD_ANY`` or
-``V4L2_FIELD_INTERLACED``. The ``VIDEO_WINDOW_CHROMAKEY`` flag moved
-into struct :c:type:`v4l2_framebuffer`, under the new
-name ``V4L2_FBUF_FLAG_CHROMAKEY``.
-
-In V4L, storing a bitmap pointer in ``clips`` and setting ``clipcount``
-to ``VIDEO_CLIP_BITMAP`` (-1) requests bitmap clipping, using a fixed
-size bitmap of 1024 × 625 bits. Struct :c:type:`v4l2_window`
-has a separate ``bitmap`` pointer field for this purpose and the bitmap
-size is determined by ``w.width`` and ``w.height``.
-
-The ``VIDIOCCAPTURE`` ioctl to enable or disable overlay was renamed to
-:ref:`VIDIOC_OVERLAY`.
-
-
-Cropping
-========
-
-To capture only a subsection of the full picture V4L defines the
-``VIDIOCGCAPTURE`` and ``VIDIOCSCAPTURE`` ioctls using struct
-``video_capture``. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` using struct
-:c:type:`v4l2_crop`, and the related
-:ref:`VIDIOC_CROPCAP` ioctl. This is a rather
-complex matter, see :ref:`crop` for details.
-
-The ``x``, ``y``, ``width`` and ``height`` fields moved into struct
-:c:type:`v4l2_rect` substructure ``c`` of struct
-:c:type:`v4l2_crop`. The ``decimation`` field was dropped. In
-the V4L2 API the scaling factor is implied by the size of the cropping
-rectangle and the size of the captured or overlaid image.
-
-The ``VIDEO_CAPTURE_ODD`` and ``VIDEO_CAPTURE_EVEN`` flags to capture
-only the odd or even field, respectively, were replaced by
-``V4L2_FIELD_TOP`` and ``V4L2_FIELD_BOTTOM`` in the field named
-``field`` of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_window`. These structures are used to
-select a capture or overlay format with the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Reading Images, Memory Mapping
-==============================
-
-
-Capturing using the read method
--------------------------------
-
-There is no essential difference between reading images from a V4L or
-V4L2 device using the :ref:`read() <func-read>` function, however V4L2
-drivers are not required to support this I/O method. Applications can
-determine if the function is available with the
-:ref:`VIDIOC_QUERYCAP` ioctl. All V4L2 devices
-exchanging data with applications must support the
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions.
-
-To select an image format and size, V4L provides the ``VIDIOCSPICT`` and
-``VIDIOCSWIN`` ioctls. V4L2 uses the general-purpose data format
-negotiation ioctls :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
-:c:type:`v4l2_format` as argument, here the struct
-:c:type:`v4l2_pix_format` named ``pix`` of its

-
-Capturing using memory mapping
-------------------------------
-
-Applications can read from V4L devices by mapping buffers in device
-memory, or more often just buffers allocated in DMA-able system memory,
-into their address space. This avoids the data copying overhead of the
-read method. V4L2 supports memory mapping as well, with a few
-differences.
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - V4L
-      - V4L2
-    * -
-      - The image format must be selected before buffers are allocated,
-	with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When no
-	format is selected the driver may use the last, possibly by
-	another application requested format.
-    * - Applications cannot change the number of buffers. The it is built
-	into the driver, unless it has a module option to change the
-	number when the driver module is loaded.
-      - The :ref:`VIDIOC_REQBUFS` ioctl allocates the
-	desired number of buffers, this is a required step in the
-	initialization sequence.
-    * - Drivers map all buffers as one contiguous range of memory. The
-	``VIDIOCGMBUF`` ioctl is available to query the number of buffers,
-	the offset of each buffer from the start of the virtual file, and
-	the overall amount of memory used, which can be used as arguments
-	for the :ref:`mmap() <func-mmap>` function.
-      - Buffers are individually mapped. The offset and size of each
-	buffer can be determined with the
-	:ref:`VIDIOC_QUERYBUF` ioctl.
-    * - The ``VIDIOCMCAPTURE`` ioctl prepares a buffer for capturing. It
-	also determines the image format for this buffer. The ioctl
-	returns immediately, eventually with an ``EAGAIN`` error code if no
-	video signal had been detected. When the driver supports more than
-	one buffer applications can call the ioctl multiple times and thus
-	have multiple outstanding capture requests.
-
-	The ``VIDIOCSYNC`` ioctl suspends execution until a particular
-	buffer has been filled.
-      - Drivers maintain an incoming and outgoing queue.
-	:ref:`VIDIOC_QBUF` enqueues any empty buffer into
-	the incoming queue. Filled buffers are dequeued from the outgoing
-	queue with the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. To wait
-	until filled buffers become available this function,
-	:ref:`select() <func-select>` or :ref:`poll() <func-poll>` can
-	be used. The :ref:`VIDIOC_STREAMON` ioctl
-	must be called once after enqueuing one or more buffers to start
-	capturing. Its counterpart
-	:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` stops capturing and
-	dequeues all buffers from both queues. Applications can query the
-	signal status, if known, with the
-	:ref:`VIDIOC_ENUMINPUT` ioctl.
-

-:ref:`mmap`.

-Reading Raw VBI Data
-====================
-
-Originally the V4L API did not specify a raw VBI capture interface, only
-the device file ``/dev/vbi`` was reserved for this purpose. The only
-driver supporting this interface was the BTTV driver, de-facto defining
-the V4L VBI interface. Reading from the device yields a raw VBI image
-with the following parameters:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct :c:type:`v4l2_vbi_format`
-      - V4L, BTTV driver
-    * - sampling_rate
-      - 28636363 Hz NTSC (or any other 525-line standard); 35468950 Hz PAL
-	and SECAM (625-line standards)
-    * - offset
-      - ?
-    * - samples_per_line
-      - 2048
-    * - sample_format
-      - V4L2_PIX_FMT_GREY. The last four bytes (a machine endianness
-	integer) contain a frame counter.
-    * - start[]
-      - 10, 273 NTSC; 22, 335 PAL and SECAM
-    * - count[]
-      - 16, 16 [#f9]_
-    * - flags
-      - 0
-
-
-Undocumented in the V4L specification, in Linux 2.3 the
-``VIDIOCGVBIFMT`` and ``VIDIOCSVBIFMT`` ioctls using struct
-``vbi_format`` were added to determine the VBI image
-parameters. These ioctls are only partially compatible with the V4L2 VBI
-interface specified in :ref:`raw-vbi`.
-
-An ``offset`` field does not exist, ``sample_format`` is supposed to be
-``VIDEO_PALETTE_RAW``, equivalent to ``V4L2_PIX_FMT_GREY``. The
-remaining fields are probably equivalent to struct
-:c:type:`v4l2_vbi_format`.
-
-Apparently only the Zoran (ZR 36120) driver implements these ioctls. The
-semantics differ from those specified for V4L2 in two ways. The
-parameters are reset on :ref:`open() <func-open>` and
-``VIDIOCSVBIFMT`` always returns an ``EINVAL`` error code if the parameters
-are invalid.
-
-
-Miscellaneous
-=============
-
-V4L2 has no equivalent of the ``VIDIOCGUNIT`` ioctl. Applications can
-find the VBI device associated with a video capture device (or vice
-versa) by reopening the device and requesting VBI data. For details see
-:ref:`open`.
-
-No replacement exists for ``VIDIOCKEY``, and the V4L functions for
-microcode programming. A new interface for MPEG compression and playback
-devices is documented in :ref:`extended-controls`.
-
-.. [#f1]
-   According to Documentation/admin-guide/devices.rst these should be symbolic links
-   to ``/dev/video0``. Note the original bttv interface is not
-   compatible with V4L or V4L2.
-
-.. [#f2]
-   According to ``Documentation/admin-guide/devices.rst`` a symbolic link to
-   ``/dev/radio0``.
-
-.. [#f3]
-   This is a custom format used by the BTTV driver, not one of the V4L2
-   standard formats.
-
-.. [#f4]
-   Presumably all V4L RGB formats are little-endian, although some
-   drivers might interpret them according to machine endianness. V4L2
-   defines little-endian, big-endian and red/blue swapped variants. For
-   details see :ref:`pixfmt-rgb`.
-
-.. [#f5]
-   ``VIDEO_PALETTE_YUV422`` and ``VIDEO_PALETTE_YUYV`` are the same
-   formats. Some V4L drivers respond to one, some to the other.
-
-.. [#f6]
-   Not to be confused with ``V4L2_PIX_FMT_YUV411P``, which is a planar
-   format.
-
-.. [#f7]
-   V4L explains this as: "RAW capture (BT848)"
-
-.. [#f8]
-   Not to be confused with ``V4L2_PIX_FMT_Y41P``, which is a packed
-   format.
-
-.. [#f9]
-   Old driver versions used different values, eventually the custom
-   ``BTTV_VBISIZE`` ioctl was added to query the correct values.

-************************************
-Streaming I/O (DMA buffer importing)
-************************************
-
-The DMABUF framework provides a generic method for sharing buffers
-between multiple devices. Device drivers that support DMABUF can export
-a DMA buffer to userspace as a file descriptor (known as the exporter
-role), import a DMA buffer from userspace using a file descriptor
-previously exported for a different or the same device (known as the
-importer role), or both. This section describes the DMABUF importer role
-API in V4L2.
-
-Refer to :ref:`DMABUF exporting <VIDIOC_EXPBUF>` for details about
-exporting V4L2 buffers as DMABUF file descriptors.
-
-Input and output devices support the streaming I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>` ioctl is set. Whether
-importing DMA buffers through DMABUF file descriptors is supported is
-determined by calling the :ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
-ioctl with the memory type set to ``V4L2_MEMORY_DMABUF``.
-
-This I/O method is dedicated to sharing DMA buffers between different
-devices, which may be V4L devices or other video-related devices (e.g.
-DRM). Buffers (planes) are allocated by a driver on behalf of an
-application. Next, these buffers are exported to the application as file
-descriptors using an API which is specific for an allocator driver. Only
-such file descriptor are exchanged. The descriptors and meta-information
-are passed in struct :c:type:`v4l2_buffer` (or in struct
-:c:type:`v4l2_plane` in the multi-planar API case). The
-driver must be switched into DMABUF I/O mode by calling the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>` with the desired buffer type.
-
-
-Example: Initiating streaming I/O with DMABUF file descriptors
-==============================================================
-
-.. code-block:: c
-
-    struct v4l2_requestbuffers reqbuf;
-
-    memset(&reqbuf, 0, sizeof (reqbuf));
-    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-    reqbuf.memory = V4L2_MEMORY_DMABUF;
-    reqbuf.count = 1;
-
-    if (ioctl(fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
-	if (errno == EINVAL)
-	    printf("Video capturing or DMABUF streaming is not supported\\n");
-	else
-	    perror("VIDIOC_REQBUFS");
-
-	exit(EXIT_FAILURE);
-    }
-
-The buffer (plane) file descriptor is passed on the fly with the
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. In case of multiplanar
-buffers, every plane can be associated with a different DMABUF
-descriptor. Although buffers are commonly cycled, applications can pass
-a different DMABUF descriptor at each :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call.
-
-Example: Queueing DMABUF using single plane API
-===============================================
-
-.. code-block:: c
-
-    int buffer_queue(int v4lfd, int index, int dmafd)
-    {
-	struct v4l2_buffer buf;
-
-	memset(&buf, 0, sizeof buf);
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-	buf.memory = V4L2_MEMORY_DMABUF;
-	buf.index = index;
-	buf.m.fd = dmafd;
-
-	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
-	    perror("VIDIOC_QBUF");
-	    return -1;
-	}
-
-	return 0;
-    }
-
-Example 3.6. Queueing DMABUF using multi plane API
-==================================================
-
-.. code-block:: c
-
-    int buffer_queue_mp(int v4lfd, int index, int dmafd[], int n_planes)
-    {
-	struct v4l2_buffer buf;
-	struct v4l2_plane planes[VIDEO_MAX_PLANES];
-	int i;
-
-	memset(&buf, 0, sizeof buf);
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
-	buf.memory = V4L2_MEMORY_DMABUF;
-	buf.index = index;
-	buf.m.planes = planes;
-	buf.length = n_planes;
-
-	memset(&planes, 0, sizeof planes);
-
-	for (i = 0; i < n_planes; ++i)
-	    buf.m.planes[i].m.fd = dmafd[i];
-
-	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
-	    perror("VIDIOC_QBUF");
-	    return -1;
-	}
-
-	return 0;
-    }
-
-Captured or displayed buffers are dequeued with the
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
-buffer at any time between the completion of the DMA and this ioctl. The
-memory is also unlocked when
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, or when the device is closed.
-
-For capturing applications it is customary to enqueue a number of empty
-buffers, to start capturing and enter the read loop. Here the
-application waits until a filled buffer can be dequeued, and re-enqueues
-the buffer when the data is no longer needed. Output applications fill
-and enqueue buffers, when enough buffers are stacked up output is
-started. In the write loop, when the application runs out of free
-buffers it must wait until an empty buffer can be dequeued and reused.
-Two methods exist to suspend execution of the application until one or
-more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
-``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions are always available.
-
-To start and stop capturing or displaying applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls.
-
-.. note::
-
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
-   both queues and unlocks all buffers as a side effect. Since there is no
-   notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
-   outputted buffers.
-
-Drivers implementing DMABUF importing I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON
-<VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls,
-and the :ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions.

-Digital Video (DV) Timings
-**************************
-
-The video standards discussed so far have been dealing with Analog TV
-and the corresponding video timings. Today there are many more different
-hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
-DVI connectors etc., that carry video signals and there is a need to
-extend the API to select the video timings for these interfaces. Since
-it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
-due to the limited bits available, a new set of ioctls was added to
-set/get video timings at the input and output.
-
-These ioctls deal with the detailed digital video timings that define
-each video format. This includes parameters such as the active video
-width and height, signal polarities, frontporches, backporches, sync
-widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
-the timings of the formats in the :ref:`cea861` and :ref:`vesadmt`
-standards.
-
-To enumerate and query the attributes of the DV timings supported by a
-device applications use the
-:ref:`VIDIOC_ENUM_DV_TIMINGS` and
-:ref:`VIDIOC_DV_TIMINGS_CAP` ioctls. To set
-DV timings for the device applications use the
-:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get
-current DV timings they use the
-:ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. To detect
-the DV timings as seen by the video receiver applications use the
-:ref:`VIDIOC_QUERY_DV_TIMINGS` ioctl.
-
-Applications can make use of the :ref:`input-capabilities` and
-:ref:`output-capabilities` flags to determine whether the digital
-video ioctls can be used with the given input or output.

-
-
-
-``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
-    Determines the exposure time of the camera sensor. The exposure time
-    is limited by the frame interval. Drivers should interpret the
-    values as 100 µs units, where the value 1 stands for 1/10000th of a
-    second, 10000 for 1 second and 100000 for 10 seconds.
-
-``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
-    When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or

-    where the value 1000 stands for +1 EV.
-
-    Increasing the exposure compensation value is equivalent to

-    Enables or disables image stabilization.
-
-``V4L2_CID_ISO_SENSITIVITY (integer menu)``
-    Determines ISO equivalent of an image sensor indicating the sensor's
-    sensitivity to light. The numbers are expressed in arithmetic scale,
-    as per :ref:`iso12232` standard, where doubling the sensor
-    sensitivity is represented by doubling the numerical ISO value.
-    Applications should interpret the values as standard ISO values
-    multiplied by 1000, e.g. control value 800 stands for ISO 0.8.
-    Drivers will usually support only a subset of standard ISO values.
-    The effect of setting this control while the
-    ``V4L2_CID_ISO_SENSITIVITY_AUTO`` control is set to a value other
-    than ``V4L2_CID_ISO_SENSITIVITY_MANUAL`` is undefined, drivers

-
-.. _v4l2-scene-mode:
-
-``V4L2_CID_SCENE_MODE``
-    (enum)
-
-enum v4l2_scene_mode -
-    This control allows to select scene programs as the camera automatic
-    modes optimized for common shooting scenes. Within these modes the
-    camera determines best exposure, aperture, focusing, light metering,
-    white balance and equivalent sensitivity. The controls of those
-    parameters are influenced by the scene mode control. An exact
-    behavior in each mode is subject to the camera specification.
-
-    When the scene mode feature is not used, this control should be set
-    to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related
-    controls are accessible. The following scene programs are defined:

-
-    * - ``V4L2_SCENE_MODE_NONE``
-      - The scene mode feature is disabled.
-    * - ``V4L2_SCENE_MODE_BACKLIGHT``
-      - Backlight. Compensates for dark shadows when light is coming from
-	behind a subject, also by automatically turning on the flash.
-    * - ``V4L2_SCENE_MODE_BEACH_SNOW``
-      - Beach and snow. This mode compensates for all-white or bright
-	scenes, which tend to look gray and low contrast, when camera's
-	automatic exposure is based on an average scene brightness. To
-	compensate, this mode automatically slightly overexposes the
-	frames. The white balance may also be adjusted to compensate for
-	the fact that reflected snow looks bluish rather than white.
-    * - ``V4L2_SCENE_MODE_CANDLELIGHT``
-      - Candle light. The camera generally raises the ISO sensitivity and
-	lowers the shutter speed. This mode compensates for relatively
-	close subject in the scene. The flash is disabled in order to
-	preserve the ambiance of the light.
-    * - ``V4L2_SCENE_MODE_DAWN_DUSK``
-      - Dawn and dusk. Preserves the colors seen in low natural light
-	before dusk and after down. The camera may turn off the flash, and
-	automatically focus at infinity. It will usually boost saturation
-	and lower the shutter speed.
-    * - ``V4L2_SCENE_MODE_FALL_COLORS``
-      - Fall colors. Increases saturation and adjusts white balance for
-	color enhancement. Pictures of autumn leaves get saturated reds
-	and yellows.
-    * - ``V4L2_SCENE_MODE_FIREWORKS``
-      - Fireworks. Long exposure times are used to capture the expanding
-	burst of light from a firework. The camera may invoke image
-	stabilization.
-    * - ``V4L2_SCENE_MODE_LANDSCAPE``
-      - Landscape. The camera may choose a small aperture to provide deep
-	depth of field and long exposure duration to help capture detail
-	in dim light conditions. The focus is fixed at infinity. Suitable
-	for distant and wide scenery.
-    * - ``V4L2_SCENE_MODE_NIGHT``
-      - Night, also known as Night Landscape. Designed for low light
-	conditions, it preserves detail in the dark areas without blowing
-	out bright objects. The camera generally sets itself to a
-	medium-to-high ISO sensitivity, with a relatively long exposure
-	time, and turns flash off. As such, there will be increased image
-	noise and the possibility of blurred image.
-    * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
-      - Party and indoor. Designed to capture indoor scenes that are lit
-	by indoor background lighting as well as the flash. The camera
-	usually increases ISO sensitivity, and adjusts exposure for the
-	low light conditions.
-    * - ``V4L2_SCENE_MODE_PORTRAIT``
-      - Portrait. The camera adjusts the aperture so that the depth of
-	field is reduced, which helps to isolate the subject against a
-	smooth background. Most cameras recognize the presence of faces in
-	the scene and focus on them. The color hue is adjusted to enhance
-	skin tones. The intensity of the flash is often reduced.
-    * - ``V4L2_SCENE_MODE_SPORTS``
-      - Sports. Significantly increases ISO and uses a fast shutter speed
-	to freeze motion of rapidly-moving subjects. Increased image noise
-	may be seen in this mode.
-    * - ``V4L2_SCENE_MODE_SUNSET``
-      - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
-	up the saturation.
-    * - ``V4L2_SCENE_MODE_TEXT``
-      - Text. It applies extra contrast and sharpness, it is typically a
-	black-and-white mode optimized for readability. Automatic focus
-	may be switched to close-up mode and this setting may also involve
-	some lens-distortion correction.

-``V4L2_CID_3A_LOCK (bitmask)``
-    This control locks or unlocks the automatic focus, exposure and
-    white balance. The automatic adjustments can be paused independently
-    by setting the corresponding lock bit to 1. The camera then retains
-    the settings until the lock bit is cleared. The following lock bits
-    are defined:
-
-    When a given algorithm is not enabled, drivers should ignore
-    requests to lock it and should return no error. An example might be
-    an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
-    ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
-    value of this control may be changed by exposure, white balance or
-    focus controls.

-    * - ``V4L2_LOCK_FOCUS``
-      - Automatic focus lock.
-
-
-
-``V4L2_CID_PAN_SPEED (integer)``
-    This control turns the camera horizontally at the specific speed.
-    The unit is undefined. A positive value moves the camera to the
-    right (clockwise when viewed from above), a negative value to the
-    left. A value of zero stops the motion if one is in progress and has
-    no effect otherwise.
-
-``V4L2_CID_TILT_SPEED (integer)``
-    This control turns the camera vertically at the specified speed. The
-    unit is undefined. A positive value moves the camera up, a negative
-    value down. A value of zero stops the motion if one is in progress
-    and has no effect otherwise.
-
-.. [#f1]
-   This control may be changed to a menu control in the future, if more
-   options are required.

-
-MFC 5.1 Control IDs
--------------------
-
-``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE (boolean)``
-    If the display delay is enabled then the decoder is forced to return
-    a CAPTURE buffer (decoded frame) after processing a certain number
-    of OUTPUT buffers. The delay can be set through
-    ``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY``. This
-    feature can be used for example for generating thumbnails of videos.
-    Applicable to the H264 decoder.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY (integer)``
-    Display delay value for H264 decoder. The decoder is forced to
-    return a decoded frame after the set 'display delay' number of
-    frames. If this number is low it may result in frames returned out
-    of display order, in addition the hardware may still be using the
-    returned buffer as a reference picture for subsequent frames.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_NUM_REF_PIC_FOR_P (integer)``
-    The number of reference pictures used for encoding a P picture.
-    Applicable to the H264 encoder.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_PADDING (boolean)``
-    Padding enable in the encoder - use a color instead of repeating
-    border pixels. Applicable to encoders.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_PADDING_YUV (integer)``
-    Padding color in the encoder. Applicable to encoders. The supplied
-    32-bit integer is interpreted as follows (bit 0 = least significant
-    bit):
-
-
-

-    Reaction coefficient for MFC rate control. Applicable to encoders.
-
-    .. note::
-
-       #. Valid only when the frame level RC is enabled.
-
-       #. For tight CBR, this field must be small (ex. 2 ~ 10). For
-	  VBR, this field must be large (ex. 100 ~ 1000).
-
-       #. It is not recommended to use the greater number than
-	  FRAME_RATE * (10^9 / BIT_RATE).
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_DARK (boolean)``
-    Adaptive rate control for dark region. Valid only when H.264 and
-    macroblock level RC is enabled
-    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
-    encoder.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_SMOOTH (boolean)``
-    Adaptive rate control for smooth region. Valid only when H.264 and
-    macroblock level RC is enabled
-    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
-    encoder.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_STATIC (boolean)``
-    Adaptive rate control for static region. Valid only when H.264 and
-    macroblock level RC is enabled
-    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
-    encoder.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_ACTIVITY (boolean)``

-    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
-    encoder.
-
-.. _v4l2-mpeg-mfc51-video-frame-skip-mode:
-
-``V4L2_CID_MPEG_MFC51_VIDEO_FRAME_SKIP_MODE``
-    (enum)
-
-enum v4l2_mpeg_mfc51_video_frame_skip_mode -
-    Indicates in what conditions the encoder should skip frames. If
-    encoding a frame would cause the encoded stream to be larger then a
-    chosen data limit then the frame will be skipped. Possible values
-    are:
-
-
-.. tabularcolumns:: |p{9.2cm}|p{8.3cm}|
-

-
-``V4L2_CID_MPEG_MFC51_VIDEO_RC_FIXED_TARGET_BIT (integer)``
-    Enable rate-control with fixed target bit. If this setting is
-    enabled, then the rate control logic of the encoder will calculate
-    the average bitrate for a GOP and keep it below or equal the set
-    bitrate target. Otherwise the rate control logic calculates the
-    overall average bitrate for the stream and keeps it below or equal
-    to the set bitrate. In the first case the average bitrate for the
-    whole stream will be smaller then the set bitrate. This is caused
-    because the average is calculated for smaller number of frames, on
-    the other hand enabling this setting will ensure that the stream
-    will meet tight bandwidth constraints. Applicable to encoders.

-*******************************
-Digital Video Control Reference
-*******************************
-
-The Digital Video control class is intended to control receivers and
-transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
-`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
-(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
-(:ref:`dp`). These controls are generally expected to be private to
-the receiver or transmitter subdevice that implements them, so they are
-only exposed on the ``/dev/v4l-subdev*`` device node.
-
-.. note::
-
-   Note that these devices can have multiple input or output pads which are
-   hooked up to e.g. HDMI connectors. Even though the subdevice will
-   receive or transmit video from/to only one of those pads, the other pads
-   can still be active when it comes to EDID (Extended Display
-   Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
-   Content Protection System, :ref:`hdcp`) processing, allowing the
-   device to do the fairly slow EDID/HDCP handling in advance. This allows
-   for quick switching between connectors.
-
-These pads appear in several of the controls in this section as
-bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
-1, etc. The maximum value of the control is the set of valid pads.
-
-
-.. _dv-control-id:
-
-Digital Video Control IDs
-=========================
-
-``V4L2_CID_DV_CLASS (class)``
-    The Digital Video class descriptor.
-
-``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
-    Many connectors have a hotplug pin which is high if EDID information
-    is available from the source. This control shows the state of the
-    hotplug pin as seen by the transmitter. Each bit corresponds to an
-    output pad on the transmitter. If an output pad does not have an
-    associated hotplug pin, then the bit for that pad will be 0. This
-    read-only control is applicable to DVI-D, HDMI and DisplayPort
-    connectors.
-
-``V4L2_CID_DV_TX_RXSENSE (bitmask)``
-    Rx Sense is the detection of pull-ups on the TMDS clock lines. This
-    normally means that the sink has left/entered standby (i.e. the
-    transmitter can sense that the receiver is ready to receive video).
-    Each bit corresponds to an output pad on the transmitter. If an
-    output pad does not have an associated Rx Sense, then the bit for
-    that pad will be 0. This read-only control is applicable to DVI-D
-    and HDMI devices.
-
-``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
-    When the transmitter sees the hotplug signal from the receiver it
-    will attempt to read the EDID. If set, then the transmitter has read
-    at least the first block (= 128 bytes). Each bit corresponds to an
-    output pad on the transmitter. If an output pad does not support
-    EDIDs, then the bit for that pad will be 0. This read-only control
-    is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_MODE``
-    (enum)
-
-enum v4l2_dv_tx_mode -
-    HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
-    mode (video + audio + auxiliary data). This control selects which
-    mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
-    This control is applicable to HDMI connectors.
-
-``V4L2_CID_DV_TX_RGB_RANGE``
-    (enum)
-
-enum v4l2_dv_rgb_range -
-    Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
-    follows the RGB quantization range specified in the standard for the
-    video interface (ie. :ref:`cea861` for HDMI).
-    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
-    standard to be compatible with sinks that have not implemented the
-    standard correctly (unfortunately quite common for HDMI and DVI-D).
-    Full range allows all possible values to be used whereas limited
-    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
-    the number of bits per component. This control is applicable to VGA,
-    DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
-    (enum)
-
-enum v4l2_dv_it_content_type -
-    Configures the IT Content Type of the transmitted video. This
-    information is sent over HDMI and DisplayPort connectors as part of
-    the AVI InfoFrame. The term 'IT Content' is used for content that
-    originates from a computer as opposed to content from a TV broadcast
-    or an analog source. The enum v4l2_dv_it_content_type defines
-    the possible content types:
-
-.. tabularcolumns:: |p{7.3cm}|p{10.4cm}|
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_DV_IT_CONTENT_TYPE_GRAPHICS``
-      - Graphics content. Pixel data should be passed unfiltered and
-	without analog reconstruction.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_PHOTO``
-      - Photo content. The content is derived from digital still pictures.
-	The content should be passed through with minimal scaling and
-	picture enhancements.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_CINEMA``
-      - Cinema content.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_GAME``
-      - Game content. Audio and video latency should be minimized.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
-      - No IT Content information is available and the ITC bit in the AVI
-	InfoFrame is set to 0.
-
-
-
-``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
-    Detects whether the receiver receives power from the source (e.g.
-    HDMI carries 5V on one of the pins). This is often used to power an
-    eeprom which contains EDID information, such that the source can
-    read the EDID even if the sink is in standby/power off. Each bit
-    corresponds to an input pad on the receiver. If an input pad
-    cannot detect whether power is present, then the bit for that pad
-    will be 0. This read-only control is applicable to DVI-D, HDMI and
-    DisplayPort connectors.
-
-``V4L2_CID_DV_RX_RGB_RANGE``
-    (enum)
-
-enum v4l2_dv_rgb_range -
-    Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO

-Flash Control Reference
-***********************
-
-The V4L2 flash controls are intended to provide generic access to flash
-controller devices. Flash controller devices are typically used in
-digital cameras.
-
-The interface can support both LED and xenon flash devices. As of
-writing this, there is no xenon flash driver using this interface.
-
-
-.. _flash-controls-use-cases:
-
-Supported use cases
-===================
-
-
-Unsynchronised LED flash (software strobe)
-------------------------------------------
-
-Unsynchronised LED flash is controlled directly by the host as the
-sensor. The flash must be enabled by the host before the exposure of the
-image starts and disabled once it ends. The host is fully responsible
-for the timing of the flash.
-
-Example of such device: Nokia N900.
-
-
-Synchronised LED flash (hardware strobe)
-----------------------------------------
-
-The synchronised LED flash is pre-programmed by the host (power and
-timeout) but controlled by the sensor through a strobe signal from the
-sensor to the flash.
-
-The sensor controls the flash duration and timing. This information
-typically must be made available to the sensor.
-
-
-LED flash as torch
-------------------
-
-LED flash may be used as torch in conjunction with another use case
-involving camera or individually.

-=========================
-
-``V4L2_CID_IMAGE_PROC_CLASS (class)``
-    The IMAGE_PROC class descriptor.
-
-``V4L2_CID_LINK_FREQ (integer menu)``
-    Data bus frequency. Together with the media bus pixel code, bus type
-    (clock cycles per sample), the data bus frequency defines the pixel
-    rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
-    elsewhere, if the device is not an image sensor). The frame rate can
-    be calculated from the pixel clock, image width and height and
-    horizontal and vertical blanking. While the pixel rate control may
-    be defined elsewhere than in the subdev containing the pixel array,
-    the frame rate cannot be obtained from that information. This is
-    because only on the pixel array it can be assumed that the vertical
-    and horizontal blanking information is exact: no other blanking is
-    allowed in the pixel array. The selection of frame rate is performed
-    by selecting the desired horizontal and vertical blanking. The unit
-    of this control is Hz.
-
-``V4L2_CID_PIXEL_RATE (64-bit integer)``
-    Pixel rate in the source pads of the subdev. This control is
-    read-only and its unit is pixels / second.
-
-``V4L2_CID_TEST_PATTERN (menu)``
-    Some capture/display/sensor devices have the capability to generate
-    test pattern images. These hardware specific test patterns can be
-    used to test if a device is working properly.
-
-``V4L2_CID_DEINTERLACING_MODE (menu)``
-    The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
-    driver specific and are documented in :ref:`v4l-drivers`.
-
-``V4L2_CID_DIGITAL_GAIN (integer)``
-    Digital gain is the value by which all colour components
-    are multiplied by. Typically the digital gain applied is the
-    control value divided by e.g. 0x100, meaning that to get no
-    digital gain the control value needs to be 0x100. The no-gain
-    configuration is also typically the default.

-
-``V4L2_CID_JPEG_CLASS (class)``
-    The JPEG class descriptor. Calling
-    :ref:`VIDIOC_QUERYCTRL` for this control will
-    return a description of this control class.
-
-``V4L2_CID_JPEG_CHROMA_SUBSAMPLING (menu)``
-    The chroma subsampling factors describe how each component of an
-    input image is sampled, in respect to maximum sample rate in each
-    spatial dimension. See :ref:`itu-t81`, clause A.1.1. for more
-    details. The ``V4L2_CID_JPEG_CHROMA_SUBSAMPLING`` control determines
-    how Cb and Cr components are downsampled after converting an input
-    image from RGB to Y'CbCr color space.

-
-    * - ``V4L2_JPEG_CHROMA_SUBSAMPLING_444``
-      - No chroma subsampling, each pixel has Y, Cr and Cb values.
-    * - ``V4L2_JPEG_CHROMA_SUBSAMPLING_422``
-      - Horizontally subsample Cr, Cb components by a factor of 2.

-      - Subsample Cr, Cb components horizontally and vertically by 2.
-    * - ``V4L2_JPEG_CHROMA_SUBSAMPLING_411``
-      - Horizontally subsample Cr, Cb components by a factor of 4.
-    * - ``V4L2_JPEG_CHROMA_SUBSAMPLING_410``
-      - Subsample Cr, Cb components horizontally by 4 and vertically by 2.
-    * - ``V4L2_JPEG_CHROMA_SUBSAMPLING_GRAY``
-      - Use only luminance component.
-
-
-
-``V4L2_CID_JPEG_RESTART_INTERVAL (integer)``
-    The restart interval determines an interval of inserting RSTm
-    markers (m = 0..7). The purpose of these markers is to additionally
-    reinitialize the encoder process, in order to process blocks of an
-    image independently. For the lossy compression processes the restart
-    interval unit is MCU (Minimum Coded Unit) and its value is contained
-    in DRI (Define Restart Interval) marker. If
-    ``V4L2_CID_JPEG_RESTART_INTERVAL`` control is set to 0, DRI and RSTm
-    markers will not be inserted.
-
-.. _jpeg-quality-control:
-
-``V4L2_CID_JPEG_COMPRESSION_QUALITY (integer)``
-    ``V4L2_CID_JPEG_COMPRESSION_QUALITY`` control determines trade-off
-    between image quality and size. It provides simpler method for
-    applications to control image quality, without a need for direct
-    reconfiguration of luminance and chrominance quantization tables. In
-    cases where a driver uses quantization tables configured directly by
-    an application, using interfaces defined elsewhere,
-    ``V4L2_CID_JPEG_COMPRESSION_QUALITY`` control should be set by
-    driver to 0.
-
-    The value range of this control is driver-specific. Only positive,
-    non-zero values are meaningful. The recommended range is 1 - 100,
-    where larger values correspond to better image quality.
-
-.. _jpeg-active-marker-control:
-
-``V4L2_CID_JPEG_ACTIVE_MARKER (bitmask)``
-    Specify which JPEG markers are included in compressed stream. This
-    control is valid only for encoders.

-RF Tuner Control Reference
-**************************
-
-The RF Tuner (RF_TUNER) class includes controls for common features of
-devices having RF tuner.
-
-In this context, RF tuner is radio receiver circuit between antenna and
-demodulator. It receives radio frequency (RF) from the antenna and
-converts that received signal to lower intermediate frequency (IF) or
-baseband frequency (BB). Tuners that could do baseband output are often
-called Zero-IF tuners. Older tuners were typically simple PLL tuners
-inside a metal box, while newer ones are highly integrated chips
-without a metal box "silicon tuners". These controls are mostly
-applicable for new feature rich silicon tuners, just because older
-tuners does not have much adjustable features.
-
-For more information about RF tuners see
-`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__
-and `RF front end <http://en.wikipedia.org/wiki/RF_front_end>`__

-
-``V4L2_CID_RF_TUNER_BANDWIDTH (integer)``
-    Filter(s) on tuner signal path are used to filter signal according
-    to receiving party needs. Driver configures filters to fulfill
-    desired bandwidth requirement. Used when
-    V4L2_CID_RF_TUNER_BANDWIDTH_AUTO is not set. Unit is in Hz. The

-    Enables/disables IF automatic gain control (AGC)
-
-``V4L2_CID_RF_TUNER_RF_GAIN (integer)``
-    The RF amplifier is the very first amplifier on the receiver signal
-    path, just right after the antenna input. The difference between the
-    LNA gain and the RF gain in this document is that the LNA gain is
-    integrated in the tuner chip while the RF gain is a separate chip.
-    There may be both RF and LNA gain controls in the same device. The
-    range and step are driver-specific.
-
-``V4L2_CID_RF_TUNER_LNA_GAIN (integer)``
-    LNA (low noise amplifier) gain is first gain stage on the RF tuner
-    signal path. It is located very close to tuner antenna input. Used
-    when ``V4L2_CID_RF_TUNER_LNA_GAIN_AUTO`` is not set. See
-    ``V4L2_CID_RF_TUNER_RF_GAIN`` to understand how RF gain and LNA gain
-    differs from the each others. The range and step are
-    driver-specific.
-
-``V4L2_CID_RF_TUNER_MIXER_GAIN (integer)``
-    Mixer gain is second gain stage on the RF tuner signal path. It is
-    located inside mixer block, where RF signal is down-converted by the
-    mixer. Used when ``V4L2_CID_RF_TUNER_MIXER_GAIN_AUTO`` is not set.
-    The range and step are driver-specific.
-
-``V4L2_CID_RF_TUNER_IF_GAIN (integer)``
-    IF gain is last gain stage on the RF tuner signal path. It is

-    are driver-specific.
-
-``V4L2_CID_RF_TUNER_PLL_LOCK (boolean)``
-    Is synthesizer PLL locked? RF tuner is receiving given frequency
-    when that control is set. This is a read-only control.

-Extended Controls API
-*********************
-
-
-Introduction
-============
-
-The control mechanism as originally designed was meant to be used for
-user settings (brightness, saturation, etc). However, it turned out to
-be a very useful model for implementing more complicated driver APIs
-where each driver implements only a subset of a larger API.
-
-The MPEG encoding API was the driving force behind designing and
-implementing this extended control mechanism: the MPEG standard is quite
-large and the currently supported hardware MPEG encoders each only
-implement a subset of this standard. Further more, many parameters
-relating to how the video is encoded into an MPEG stream are specific to
-the MPEG encoding chip since the MPEG standard only defines the format
-of the resulting MPEG stream, not how the video is actually encoded into
-that format.
-
-Unfortunately, the original control API lacked some features needed for
-these new uses and so it was extended into the (not terribly originally
-named) extended control API.
-
-Even though the MPEG encoding API was the first effort to use the
-Extended Control API, nowadays there are also other classes of Extended
-Controls, such as Camera Controls and FM Transmitter Controls. The
-Extended Controls API as well as all Extended Controls classes are
-described in the following text.
-
-
-The Extended Control API
-========================
-
-Three new ioctls are available:
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`. These ioctls act
-on arrays of controls (as opposed to the
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls that act on a single
-control). This is needed since it is often required to atomically change
-several controls at once.
-
-Each of the new ioctls expects a pointer to a struct
-:c:type:`v4l2_ext_controls`. This structure
-contains a pointer to the control array, a count of the number of
-controls in that array and a control class. Control classes are used to
-group similar controls into a single class. For example, control class
-``V4L2_CTRL_CLASS_USER`` contains all user controls (i. e. all controls
-that can also be set using the old :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
-ioctl). Control class ``V4L2_CTRL_CLASS_MPEG`` contains all controls
-relating to MPEG encoding, etc.
-
-All controls in the control array must belong to the specified control
-class. An error is returned if this is not the case.
-
-It is also possible to use an empty control array (``count`` == 0) to check
-whether the specified control class is supported.
-
-The control array is a struct
-:c:type:`v4l2_ext_control` array. The
-struct :c:type:`v4l2_ext_control` is very similar to
-struct :c:type:`v4l2_control`, except for the fact that
-it also allows for 64-bit values and pointers to be passed.
-
-Since the struct :c:type:`v4l2_ext_control` supports
-pointers it is now also possible to have controls with compound types
-such as N-dimensional arrays and/or structures. You need to specify the
-``V4L2_CTRL_FLAG_NEXT_COMPOUND`` when enumerating controls to actually
-be able to see such compound controls. In other words, these controls
-with compound types should only be used programmatically.
-
-Since such compound controls need to expose more information about
-themselves than is possible with :ref:`VIDIOC_QUERYCTRL <VIDIOC_QUERYCTRL>`
-the :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
-particular, this ioctl gives the dimensions of the N-dimensional array if
-this control consists of more than one element.
-
-.. note::
-
-   #. It is important to realize that due to the flexibility of controls it is
-      necessary to check whether the control you want to set actually is
-      supported in the driver and what the valid range of values is. So use
-      :ref:`VIDIOC_QUERYCTRL` to check this.
-
-   #. It is possible that some of the menu indices in a control of
-      type ``V4L2_CTRL_TYPE_MENU`` may not be supported (``VIDIOC_QUERYMENU``
-      will return an error). A good example is the list of supported MPEG
-      audio bitrates. Some drivers only support one or two bitrates, others
-      support a wider range.
-
-All controls use machine endianness.
-
-
-Enumerating Extended Controls
-=============================
-
-The recommended way to enumerate over the extended controls is by using
-:ref:`VIDIOC_QUERYCTRL` in combination with the
-``V4L2_CTRL_FLAG_NEXT_CTRL`` flag:
-
-
-.. code-block:: c
-
-    struct v4l2_queryctrl qctrl;
-
-    qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
-    while (0 == ioctl (fd, VIDIOC_QUERYCTRL, &qctrl)) {
-	/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-    }
-
-The initial control ID is set to 0 ORed with the
-``V4L2_CTRL_FLAG_NEXT_CTRL`` flag. The ``VIDIOC_QUERYCTRL`` ioctl will
-return the first control with a higher ID than the specified one. When
-no such controls are found an error is returned.
-
-If you want to get all controls within a specific control class, then
-you can set the initial ``qctrl.id`` value to the control class and add
-an extra check to break out of the loop when a control of another
-control class is found:
-
-
-.. code-block:: c
-
-    qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
-    while (0 == ioctl(fd, VIDIOC_QUERYCTRL, &qctrl)) {
-	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
-	    break;
-	/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-    }
-
-The 32-bit ``qctrl.id`` value is subdivided into three bit ranges: the
-top 4 bits are reserved for flags (e. g. ``V4L2_CTRL_FLAG_NEXT_CTRL``)
-and are not actually part of the ID. The remaining 28 bits form the
-control ID, of which the most significant 12 bits define the control
-class and the least significant 16 bits identify the control within the
-control class. It is guaranteed that these last 16 bits are always
-non-zero for controls. The range of 0x1000 and up are reserved for
-driver-specific controls. The macro ``V4L2_CTRL_ID2CLASS(id)`` returns
-the control class ID based on a control ID.
-
-If the driver does not support extended controls, then
-``VIDIOC_QUERYCTRL`` will fail when used in combination with
-``V4L2_CTRL_FLAG_NEXT_CTRL``. In that case the old method of enumerating
-control should be used (see :ref:`enum_all_controls`). But if it is
-supported, then it is guaranteed to enumerate over all controls,
-including driver-private controls.
-
-
-Creating Control Panels
-=======================
-
-It is possible to create control panels for a graphical user interface
-where the user can select the various controls. Basically you will have
-to iterate over all controls using the method described above. Each
-control class starts with a control of type
-``V4L2_CTRL_TYPE_CTRL_CLASS``. ``VIDIOC_QUERYCTRL`` will return the name
-of this control class which can be used as the title of a tab page
-within a control panel.
-
-The flags field of struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` also
-contains hints on the behavior of the control. See the
-:ref:`VIDIOC_QUERYCTRL` documentation for more
-details.

-
-***********
-Field Order
-***********
-
-We have to distinguish between progressive and interlaced video.
-Progressive video transmits all lines of a video image sequentially.
-Interlaced video divides an image into two fields, containing only the
-odd and even lines of the image, respectively. Alternating the so called
-odd and even field are transmitted, and due to a small delay between
-fields a cathode ray TV displays the lines interleaved, yielding the
-original frame. This curious technique was invented because at refresh
-rates similar to film the image would fade out too quickly. Transmitting
-fields reduces the flicker without the necessity of doubling the frame
-rate and with it the bandwidth required for each channel.
-
-It is important to understand a video camera does not expose one frame
-at a time, merely transmitting the frames separated into fields. The
-fields are in fact captured at two different instances in time. An
-object on screen may well move between one field and the next. For
-applications analysing motion it is of paramount importance to recognize
-which field of a frame is older, the *temporal order*.
-
-When the driver provides or accepts images field by field rather than
-interleaved, it is also important applications understand how the fields
-combine to frames. We distinguish between top (aka odd) and bottom (aka
-even) fields, the *spatial order*: The first line of the top field is
-the first line of an interlaced frame, the first line of the bottom
-field is the second line of that frame.
-
-However because fields were captured one after the other, arguing
-whether a frame commences with the top or bottom field is pointless. Any
-two successive top and bottom, or bottom and top fields yield a valid
-frame. Only when the source was progressive to begin with, e. g. when
-transferring film to video, two fields may come from the same frame,
-creating a natural order.
-
-Counter to intuition the top field is not necessarily the older field.
-Whether the older field contains the top or bottom lines is a convention
-determined by the video standard. Hence the distinction between temporal
-and spatial order of fields. The diagrams below should make this
-clearer.
-
-In V4L it is assumed that all video cameras transmit fields on the media
-bus in the same order they were captured, so if the top field was
-captured first (is the older field), the top field is also transmitted
-first on the bus.
-
-All video capture and output devices must report the current field
-order. Some drivers may permit the selection of a different order, to
-this end applications initialize the ``field`` field of struct
-:c:type:`v4l2_pix_format` before calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. If this is not desired it
-should have the value ``V4L2_FIELD_ANY`` (0).

-      - 0
-      - Applications request this field order when any field format
-	is acceptable. Drivers choose depending on hardware capabilities or
-	e.g. the requested image size, and return the actual field order.
-	Drivers must never return ``V4L2_FIELD_ANY``.
-	If multiple field orders are possible the
-	driver must choose one of the possible field orders during
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
-	:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`. struct

-    * - ``V4L2_FIELD_NONE``
-      - 1
-      - Images are in progressive (frame-based) format, not interlaced
-        (field-based).
-    * - ``V4L2_FIELD_TOP``
-      - 2
-      - Images consist of the top (aka odd) field only.
-    * - ``V4L2_FIELD_BOTTOM``
-      - 3
-      - Images consist of the bottom (aka even) field only. Applications
-	may wish to prevent a device from capturing interlaced images
-	because they will have "comb" or "feathering" artefacts around
-	moving objects.
-    * - ``V4L2_FIELD_INTERLACED``
-      - 4
-      - Images contain both fields, interleaved line by line. The temporal
-	order of the fields (whether the top or bottom field is older)
-	depends on the current video standard. In M/NTSC the bottom
-	field is the older field. In all other standards the top field
-	is the older field.
-    * - ``V4L2_FIELD_SEQ_TB``
-      - 5
-      - Images contain both fields, the top field lines are stored first
-	in memory, immediately followed by the bottom field lines. Fields
-	are always stored in temporal order, the older one first in
-	memory. Image sizes refer to the frame, not fields.
-    * - ``V4L2_FIELD_SEQ_BT``
-      - 6
-      - Images contain both fields, the bottom field lines are stored
-	first in memory, immediately followed by the top field lines.
-	Fields are always stored in temporal order, the older one first in
-	memory. Image sizes refer to the frame, not fields.
-    * - ``V4L2_FIELD_ALTERNATE``
-      - 7
-      - The two fields of a frame are passed in separate buffers, in
-	temporal order, i. e. the older one first. To indicate the field
-	parity (whether the current field is a top or bottom field) the
-	driver or application, depending on data direction, must set
-	struct :c:type:`v4l2_buffer` ``field`` to
-	``V4L2_FIELD_TOP`` or ``V4L2_FIELD_BOTTOM``. Any two successive
-	fields pair to build a frame. If fields are successive, without
-	any dropped fields between them (fields can drop individually),
-	can be determined from the struct
-	:c:type:`v4l2_buffer` ``sequence`` field. This
-	format cannot be selected when using the read/write I/O method
-	since there is no way to communicate if a field was a top or
-	bottom field.
-    * - ``V4L2_FIELD_INTERLACED_TB``
-      - 8
-      - Images contain both fields, interleaved line by line, top field
-	first. The top field is the older field.

-Data Formats
-************
-
-
-Data Format Negotiation
-=======================
-
-Different devices exchange different kinds of data with applications,
-for example video images, raw or sliced VBI data, RDS datagrams. Even
-within one kind many different formats are possible, in particular there is an
-abundance of image formats. Although drivers must provide a default and
-the selection persists across closing and reopening a device,
-applications should always negotiate a data format before engaging in
-data exchange. Negotiation means the application asks for a particular
-format and the driver selects and reports the best the hardware can do
-to satisfy the request. Of course applications can also just query the
-current selection.
-
-A single mechanism exists to negotiate all data formats using the
-aggregate struct :c:type:`v4l2_format` and the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls. Additionally the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to examine
-what the hardware *could* do, without actually selecting a new data
-format. The data formats supported by the V4L2 API are covered in the
-respective device section in :ref:`devices`. For a closer look at
-image formats see :ref:`pixfmt`.
-
-The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl is a major turning-point in the
-initialization sequence. Prior to this point multiple panel applications
-can access the same device concurrently to select the current input,
-change controls or modify other properties. The first :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-assigns a logical stream (video data, VBI data etc.) exclusively to one
-file descriptor.
-
-Exclusive means no other application, more precisely no other file
-descriptor, can grab this stream or change device properties
-inconsistent with the negotiated parameters. A video standard change for
-example, when the new standard uses a different number of scan lines,
-can invalidate the selected image format. Therefore only the file
-descriptor owning the stream can make invalidating changes. Accordingly
-multiple file descriptors which grabbed different logical streams
-prevent each other from interfering with their settings. When for
-example video overlay is about to start or already in progress,
-simultaneous video capturing may be restricted to the same cropping and
-image size.
-
-When applications omit the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl its locking side
-effects are implied by the next step, the selection of an I/O method
-with the :ref:`VIDIOC_REQBUFS` ioctl or implicit
-with the first :ref:`read() <func-read>` or
-:ref:`write() <func-write>` call.
-
-Generally only one logical stream can be assigned to a file descriptor,
-the exception being drivers permitting simultaneous video capturing and
-overlay using the same file descriptor for compatibility with V4L and
-earlier versions of V4L2. Switching the logical stream or returning into
-"panel mode" is possible by closing and reopening the device. Drivers
-*may* support a switch using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
-
-All drivers exchanging data with applications must support the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. Implementation of the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is highly recommended but optional.
-
-
-Image Format Enumeration
-========================
-
-Apart of the generic format negotiation functions a special ioctl to
-enumerate all image formats supported by video capture, overlay or
-output devices is available. [#f1]_
-
-The :ref:`VIDIOC_ENUM_FMT` ioctl must be supported
-by all drivers exchanging image data with applications.
-
-.. important::
-
-    Drivers are not supposed to convert image formats in kernel space.
-    They must enumerate only formats directly supported by the hardware.
-    If necessary driver writers should publish an example conversion
-    routine or library for integration into applications.
-
-.. [#f1]
-   Enumerating formats an application has no a-priori knowledge of
-   (otherwise it could explicitly ask for them and need not enumerate)
-   seems useless, but there are applications serving as proxy between
-   drivers and the actual video applications for which this is useful.

-
-Description
-===========
-
-The :ref:`ioctl() <func-ioctl>` function is used to program V4L2 devices. The
-argument ``fd`` must be an open file descriptor. An ioctl ``request``
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes. Macros and
-defines specifying V4L2 ioctl requests are located in the
-``videodev2.h`` header file. Applications should use their own copy, not
-include the version in the kernel sources on the system they compile on.
-All V4L2 ioctl requests, their respective function and parameters are
-specified in :ref:`user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-    #include <sys/mman.h>
-
-
-.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
-    :name: v4l2-mmap
-
-Arguments
-=========
-
-``start``
-    Map the buffer to this address in the application's address space.
-    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
-    multiple of the pagesize and mmap will fail when the specified
-    address cannot be used. Use of this option is discouraged;
-    applications should just specify a ``NULL`` pointer here.
-
-``length``
-    Length of the memory area to map. This must be the same value as
-    returned by the driver in the struct
-    :c:type:`v4l2_buffer` ``length`` field for the
-    single-planar API, and the same value as returned by the driver in
-    the struct :c:type:`v4l2_plane` ``length`` field for
-    the multi-planar API.
-
-``prot``
-    The ``prot`` argument describes the desired memory protection.
-    Regardless of the device type and the direction of data exchange it
-    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
-    and write access to image buffers. Drivers should support at least
-    this combination of flags.
-
-    .. note::
-
-      #. The Linux ``videobuf`` kernel module, which is used by some
-	 drivers supports only ``PROT_READ`` | ``PROT_WRITE``. When the
-	 driver does not support the desired protection, the
-	 :ref:`mmap() <func-mmap>` function fails.
-
-      #. Device memory accesses (e. g. the memory on a graphics card
-	 with video capturing hardware) may incur a performance penalty
-	 compared to main memory accesses, or reads may be significantly
-	 slower than writes or vice versa. Other I/O methods may be more
-	 efficient in such case.
-
-``flags``
-    The ``flags`` parameter specifies the type of the mapped object,
-    mapping options and whether modifications made to the mapped copy of
-    the page are private to the process or are to be shared with other
-    references.
-
-    ``MAP_FIXED`` requests that the driver selects no other address than
-    the one specified. If the specified address cannot be used,
-    :ref:`mmap() <func-mmap>` will fail. If ``MAP_FIXED`` is specified,
-    ``start`` must be a multiple of the pagesize. Use of this option is
-    discouraged.
-
-    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
-    ``MAP_SHARED`` allows applications to share the mapped memory with
-    other (e. g. child-) processes.
-
-    .. note::
-
-       The Linux ``videobuf`` module  which is used by some
-       drivers supports only ``MAP_SHARED``. ``MAP_PRIVATE`` requests
-       copy-on-write semantics. V4L2 applications should not set the
-       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
-       flags.
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``offset``
-    Offset of the buffer in device memory. This must be the same value
-    as returned by the driver in the struct
-    :c:type:`v4l2_buffer` ``m`` union ``offset`` field for
-    the single-planar API, and the same value as returned by the driver
-    in the struct :c:type:`v4l2_plane` ``m`` union
-    ``mem_offset`` field for the multi-planar API.
-
-
-Description
-===========
-
-The :ref:`mmap() <func-mmap>` function asks to map ``length`` bytes starting at
-``offset`` in the memory of the device specified by ``fd`` into the
-application address space, preferably at address ``start``. This latter
-address is a hint only, and is usually specified as 0.
-
-Suitable length and offset parameters are queried with the
-:ref:`VIDIOC_QUERYBUF` ioctl. Buffers must be
-allocated with the :ref:`VIDIOC_REQBUFS` ioctl
-before they can be queried.
-
-To unmap buffers the :ref:`munmap() <func-munmap>` function is used.
-
-
-Return Value
-============
-
-On success :ref:`mmap() <func-mmap>` returns a pointer to the mapped buffer. On
-error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
-appropriately. Possible error codes are:
-
-EBADF
-    ``fd`` is not a valid file descriptor.
-
-EACCES
-    ``fd`` is not open for reading and writing.
-
-EINVAL
-    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
-    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
-
-    The ``flags`` or ``prot`` value is not supported.
-
-    No buffers have been allocated with the
-    :ref:`VIDIOC_REQBUFS` ioctl.
-
-ENOMEM
-    Not enough physical or virtual memory was available to complete the
-    request.

-
-``device_name``
-    Device to be opened.
-

-===========
-
-To open a V4L2 device applications call :ref:`open() <func-open>` with the

-
-On success :ref:`open() <func-open>` returns the new file descriptor. On error
--1 is returned, and the ``errno`` variable is set appropriately.
-Possible error codes are:
-
-EACCES
-    The caller has no permission to access the device.

-
-
-.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
-    :name: v4l2-poll
-
-Arguments
-=========
-
-
-
-Description
-===========
-
-With the :ref:`poll() <func-poll>` function applications can suspend execution
-until the driver has captured data or is ready to accept data for
-output.
-
-When streaming I/O has been negotiated this function waits until a
-buffer has been filled by the capture device and can be dequeued with
-the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. For output devices this
-function waits until the device is ready to accept a new buffer to be
-queued up with the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl for
-display. When buffers are already in the outgoing queue of the driver
-(capture) or the incoming queue isn't full (display) the function
-returns immediately.
-
-On success :ref:`poll() <func-poll>` returns the number of file descriptors
-that have been selected (that is, file descriptors for which the
-``revents`` field of the respective :c:func:`struct pollfd` structure
-is non-zero). Capture devices set the ``POLLIN`` and ``POLLRDNORM``
-flags in the ``revents`` field, output devices the ``POLLOUT`` and
-``POLLWRNORM`` flags. When the function timed out it returns a value of
-zero, on failure it returns -1 and the ``errno`` variable is set
-appropriately. When the application did not call
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` the :ref:`poll() <func-poll>`
-function succeeds, but sets the ``POLLERR`` flag in the ``revents``
-field. When the application has called
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` for a capture device but
-hasn't yet called :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, the
-:ref:`poll() <func-poll>` function succeeds and sets the ``POLLERR`` flag in
-the ``revents`` field. For output devices this same situation will cause
-:ref:`poll() <func-poll>` to succeed as well, but it sets the ``POLLOUT`` and
-``POLLWRNORM`` flags in the ``revents`` field.
-
-If an event occurred (see :ref:`VIDIOC_DQEVENT`)
-then ``POLLPRI`` will be set in the ``revents`` field and
-:ref:`poll() <func-poll>` will return.
-
-When use of the :ref:`read() <func-read>` function has been negotiated and the
-driver does not capture yet, the :ref:`poll() <func-poll>` function starts
-capturing. When that fails it returns a ``POLLERR`` as above. Otherwise
-it waits until data has been captured and can be read. When the driver
-captures continuously (as opposed to, for example, still images) the
-function may return immediately.
-
-When use of the :ref:`write() <func-write>` function has been negotiated and the
-driver does not stream yet, the :ref:`poll() <func-poll>` function starts
-streaming. When that fails it returns a ``POLLERR`` as above. Otherwise
-it waits until the driver is ready for a non-blocking
-:ref:`write() <func-write>` call.
-
-If the caller is only interested in events (just ``POLLPRI`` is set in
-the ``events`` field), then :ref:`poll() <func-poll>` will *not* start
-streaming if the driver does not stream yet. This makes it possible to
-just poll for events and not for buffers.
-
-All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
-function or streaming I/O must also support the :ref:`poll() <func-poll>`
-function.
-
-For more details see the :ref:`poll() <func-poll>` manual page.
-
-
-Return Value
-============
-
-On success, :ref:`poll() <func-poll>` returns the number structures which have
-non-zero ``revents`` fields, or zero if the call timed out. On error -1
-is returned, and the ``errno`` variable is set appropriately:
-
-EBADF
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-EBUSY
-    The driver does not support multiple read or write streams and the
-    device is already in use.
-
-EFAULT
-    ``ufds`` references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal.
-
-EINVAL
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-
-
-.. c:function:: ssize_t read( int fd, void *buf, size_t count )
-    :name: v4l2-read
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``buf``
-   Buffer to be filled
-
-``count``
-  Max number of bytes to read
-
-Description
-===========
-
-:ref:`read() <func-read>` attempts to read up to ``count`` bytes from file
-descriptor ``fd`` into the buffer starting at ``buf``. The layout of the
-data in the buffer is discussed in the respective device interface
-section, see ##. If ``count`` is zero, :ref:`read() <func-read>` returns zero
-and has no other results. If ``count`` is greater than ``SSIZE_MAX``,
-the result is unspecified. Regardless of the ``count`` value each
-:ref:`read() <func-read>` call will provide at most one frame (two fields)
-worth of data.
-
-By default :ref:`read() <func-read>` blocks until data becomes available. When
-the ``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>`
-function it returns immediately with an ``EAGAIN`` error code when no data
-is available. The :ref:`select() <func-select>` or
-:ref:`poll() <func-poll>` functions can always be used to suspend
-execution until data becomes available. All drivers supporting the
-:ref:`read() <func-read>` function must also support :ref:`select() <func-select>` and
-:ref:`poll() <func-poll>`.
-
-Drivers can implement read functionality in different ways, using a
-single or multiple buffers and discarding the oldest or newest frames
-once the internal buffers are filled.
-
-:ref:`read() <func-read>` never returns a "snapshot" of a buffer being filled.
-Using a single buffer the driver will stop capturing when the
-application starts reading the buffer until the read is finished. Thus
-only the period of the vertical blanking interval is available for
-reading, or the capture rate must fall below the nominal frame rate of
-the video standard.
-
-The behavior of :ref:`read() <func-read>` when called during the active picture
-period or the vertical blanking separating the top and bottom field
-depends on the discarding policy. A driver discarding the oldest frames
-keeps capturing into an internal buffer, continuously overwriting the
-previously, not read frame, and returns the frame being received at the
-time of the :ref:`read() <func-read>` call as soon as it is complete.
-
-A driver discarding the newest frames stops capturing until the next
-:ref:`read() <func-read>` call. The frame being received at :ref:`read() <func-read>`
-time is discarded, returning the following frame instead. Again this
-implies a reduction of the capture rate to one half or less of the
-nominal frame rate. An example of this model is the video read mode of
-the bttv driver, initiating a DMA to user memory when :ref:`read() <func-read>`
-is called and returning when the DMA finished.
-
-In the multiple buffer model drivers maintain a ring of internal
-buffers, automatically advancing to the next free buffer. This allows
-continuous capturing when the application can empty the buffers fast
-enough. Again, the behavior when the driver runs out of free buffers
-depends on the discarding policy.
-
-Applications can get and set the number of buffers used internally by
-the driver with the :ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
-:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctls. They are optional,
-however. The discarding policy is not reported and cannot be changed.
-For minimum requirements see :ref:`devices`.
-
-
-Return Value
-============
-
-On success, the number of bytes read is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame. This may happen for example because
-:ref:`read() <func-read>` was interrupted by a signal. On error, -1 is
-returned, and the ``errno`` variable is set appropriately. In this case
-the next read will start at the beginning of a new frame. Possible error
-codes are:
-
-EAGAIN
-    Non-blocking I/O has been selected using O_NONBLOCK and no data was
-    immediately available for reading.
-
-EBADF
-    ``fd`` is not a valid file descriptor or is not open for reading, or
-    the process already has the maximum number of files open.
-
-EBUSY
-    The driver does not support multiple read streams and the device is
-    already in use.
-
-EFAULT
-    ``buf`` references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal before any data was read.
-
-EIO
-    I/O error. This indicates some hardware problem or a failure to
-    communicate with a remote device (USB camera etc.).
-
-EINVAL
-    The :ref:`read() <func-read>` function is not supported by this driver, not
-    on this device, or generally not on this type of device.

-Changes of the V4L2 API
-***********************
-
-Soon after the V4L API was added to the kernel it was criticised as too
-inflexible. In August 1998 Bill Dirks proposed a number of improvements
-and began to work on documentation, example drivers and applications.
-With the help of other volunteers this eventually became the V4L2 API,
-not just an extension but a replacement for the V4L API. However it took
-another four years and two stable kernel releases until the new API was
-finally accepted for inclusion into the kernel in its present form.
-
-
-Early Versions
-==============
-
-1998-08-20: First version.
-
-1998-08-27: The :ref:`select() <func-select>` function was introduced.
-
-1998-09-10: New video standard interface.
-
-1998-09-18: The ``VIDIOC_NONCAP`` ioctl was replaced by the otherwise
-meaningless ``O_TRUNC`` :ref:`open() <func-open>` flag, and the
-aliases ``O_NONCAP`` and ``O_NOIO`` were defined. Applications can set
-this flag if they intend to access controls only, as opposed to capture
-applications which need exclusive access. The ``VIDEO_STD_XXX``
-identifiers are now ordinals instead of flags, and the
-``video_std_construct()`` helper function takes id and
-transmission arguments.
-
-1998-09-28: Revamped video standard. Made video controls individually
-enumerable.
-
-1998-10-02: The ``id`` field was removed from struct
-struct ``video_standard`` and the color subcarrier fields were
-renamed. The :ref:`VIDIOC_QUERYSTD` ioctl was
-renamed to :ref:`VIDIOC_ENUMSTD`,
-:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` to
-:ref:`VIDIOC_ENUMINPUT`. A first draft of the
-Codec API was released.
-
-1998-11-08: Many minor changes. Most symbols have been renamed. Some
-material changes to struct :c:type:`v4l2_capability`.
-
-1998-11-12: The read/write directon of some ioctls was misdefined.
-
-1998-11-14: ``V4L2_PIX_FMT_RGB24`` changed to ``V4L2_PIX_FMT_BGR24``,
-and ``V4L2_PIX_FMT_RGB32`` changed to ``V4L2_PIX_FMT_BGR32``. Audio
-controls are now accessible with the
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls under names starting
-with ``V4L2_CID_AUDIO``. The ``V4L2_MAJOR`` define was removed from
-``videodev.h`` since it was only used once in the ``videodev`` kernel
-module. The ``YUV422`` and ``YUV411`` planar image formats were added.
-
-1998-11-28: A few ioctl symbols changed. Interfaces for codecs and video
-output devices were added.
-
-1999-01-14: A raw VBI capture interface was added.
-
-1999-01-19: The ``VIDIOC_NEXTBUF`` ioctl was removed.
-
-
-V4L2 Version 0.16 1999-01-31
-============================
-
-1999-01-27: There is now one QBUF ioctl, VIDIOC_QWBUF and VIDIOC_QRBUF
-are gone. VIDIOC_QBUF takes a v4l2_buffer as a parameter. Added
-digital zoom (cropping) controls.
-
-
-V4L2 Version 0.18 1999-03-16
-============================
-
-Added a v4l to V4L2 ioctl compatibility layer to videodev.c. Driver
-writers, this changes how you implement your ioctl handler. See the
-Driver Writer's Guide. Added some more control id codes.
-
-
-V4L2 Version 0.19 1999-06-05
-============================
-
-1999-03-18: Fill in the category and catname fields of v4l2_queryctrl
-objects before passing them to the driver. Required a minor change to
-the VIDIOC_QUERYCTRL handlers in the sample drivers.
-
-1999-03-31: Better compatibility for v4l memory capture ioctls. Requires
-changes to drivers to fully support new compatibility features, see
-Driver Writer's Guide and v4l2cap.c. Added new control IDs:
-V4L2_CID_HFLIP, _VFLIP. Changed V4L2_PIX_FMT_YUV422P to _YUV422P,
-and _YUV411P to _YUV411P.
-
-1999-04-04: Added a few more control IDs.
-
-1999-04-07: Added the button control type.
-
-1999-05-02: Fixed a typo in videodev.h, and added the
-V4L2_CTRL_FLAG_GRAYED (later V4L2_CTRL_FLAG_GRABBED) flag.
-
-1999-05-20: Definition of VIDIOC_G_CTRL was wrong causing a
-malfunction of this ioctl.
-
-1999-06-05: Changed the value of V4L2_CID_WHITENESS.
-
-
-V4L2 Version 0.20 (1999-09-10)
-==============================
-
-Version 0.20 introduced a number of changes which were *not backward
-compatible* with 0.19 and earlier versions. Purpose of these changes was
-to simplify the API, while making it more extensible and following
-common Linux driver API conventions.
-
-1. Some typos in ``V4L2_FMT_FLAG`` symbols were fixed. struct
-   :c:type:`v4l2_clip` was changed for compatibility with
-   v4l. (1999-08-30)
-
-2. ``V4L2_TUNER_SUB_LANG1`` was added. (1999-09-05)
-
-3. All ioctl() commands that used an integer argument now take a pointer
-   to an integer. Where it makes sense, ioctls will return the actual
-   new value in the integer pointed to by the argument, a common
-   convention in the V4L2 API. The affected ioctls are: VIDIOC_PREVIEW,
-   VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_S_FREQ,
-   VIDIOC_S_INPUT, VIDIOC_S_OUTPUT, VIDIOC_S_EFFECT. For example
-
-
-   .. code-block:: c
-
-       err = ioctl (fd, VIDIOC_XXX, V4L2_XXX);
-
-   becomes
-
-
-   .. code-block:: c
-
-       int a = V4L2_XXX; err = ioctl(fd, VIDIOC_XXX, &a);
-
-4. All the different get- and set-format commands were swept into one
-   :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-   :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl taking a union and a
-   type field selecting the union member as parameter. Purpose is to
-   simplify the API by eliminating several ioctls and to allow new and
-   driver private data streams without adding new ioctls.
-
-   This change obsoletes the following ioctls: ``VIDIOC_S_INFMT``,
-   ``VIDIOC_G_INFMT``, ``VIDIOC_S_OUTFMT``, ``VIDIOC_G_OUTFMT``,
-   ``VIDIOC_S_VBIFMT`` and ``VIDIOC_G_VBIFMT``. The image format
-   structure struct :c:type:`v4l2_format` was renamed to struct
-   :c:type:`v4l2_pix_format`, while struct
-   :c:type:`v4l2_format` is now the envelopping structure
-   for all format negotiations.
-
-5. Similar to the changes above, the ``VIDIOC_G_PARM`` and
-   ``VIDIOC_S_PARM`` ioctls were merged with ``VIDIOC_G_OUTPARM`` and
-   ``VIDIOC_S_OUTPARM``. A ``type`` field in the new struct
-   :c:type:`v4l2_streamparm` selects the respective
-   union member.
-
-   This change obsoletes the ``VIDIOC_G_OUTPARM`` and
-   ``VIDIOC_S_OUTPARM`` ioctls.
-
-6. Control enumeration was simplified, and two new control flags were
-   introduced and one dropped. The ``catname`` field was replaced by a
-   ``group`` field.
-
-   Drivers can now flag unsupported and temporarily unavailable controls
-   with ``V4L2_CTRL_FLAG_DISABLED`` and ``V4L2_CTRL_FLAG_GRABBED``
-   respectively. The ``group`` name indicates a possibly narrower
-   classification than the ``category``. In other words, there may be
-   multiple groups within a category. Controls within a group would
-   typically be drawn within a group box. Controls in different
-   categories might have a greater separation, or may even appear in
-   separate windows.
-
-7. The struct :c:type:`v4l2_buffer` ``timestamp`` was
-   changed to a 64 bit integer, containing the sampling or output time
-   of the frame in nanoseconds. Additionally timestamps will be in
-   absolute system time, not starting from zero at the beginning of a
-   stream. The data type name for timestamps is stamp_t, defined as a
-   signed 64-bit integer. Output devices should not send a buffer out
-   until the time in the timestamp field has arrived. I would like to
-   follow SGI's lead, and adopt a multimedia timestamping system like
-   their UST (Unadjusted System Time). See
-   http://web.archive.org/web/\*/http://reality.sgi.com
-   /cpirazzi_engr/lg/time/intro.html. UST uses timestamps that are
-   64-bit signed integers (not struct timeval's) and given in nanosecond
-   units. The UST clock starts at zero when the system is booted and
-   runs continuously and uniformly. It takes a little over 292 years for
-   UST to overflow. There is no way to set the UST clock. The regular
-   Linux time-of-day clock can be changed periodically, which would
-   cause errors if it were being used for timestamping a multimedia
-   stream. A real UST style clock will require some support in the
-   kernel that is not there yet. But in anticipation, I will change the
-   timestamp field to a 64-bit integer, and I will change the
-   v4l2_masterclock_gettime() function (used only by drivers) to
-   return a 64-bit integer.
-
-8. A ``sequence`` field was added to struct
-   :c:type:`v4l2_buffer`. The ``sequence`` field counts
-   captured frames, it is ignored by output devices. When a capture
-   driver drops a frame, the sequence number of that frame is skipped.
-
-
-V4L2 Version 0.20 incremental changes
-=====================================
-
-1999-12-23: In struct :c:type:`v4l2_vbi_format` the
-``reserved1`` field became ``offset``. Previously drivers were required
-to clear the ``reserved1`` field.
-
-2000-01-13: The ``V4L2_FMT_FLAG_NOT_INTERLACED`` flag was added.
-
-2000-07-31: The ``linux/poll.h`` header is now included by
-``videodev.h`` for compatibility with the original ``videodev.h`` file.
-
-2000-11-20: ``V4L2_TYPE_VBI_OUTPUT`` and ``V4L2_PIX_FMT_Y41P`` were
-added.
-
-2000-11-25: ``V4L2_TYPE_VBI_INPUT`` was added.
-
-2000-12-04: A couple typos in symbol names were fixed.
-
-2001-01-18: To avoid namespace conflicts the ``fourcc`` macro defined in
-the ``videodev.h`` header file was renamed to ``v4l2_fourcc``.
-
-2001-01-25: A possible driver-level compatibility problem between the
-``videodev.h`` file in Linux 2.4.0 and the ``videodev.h`` file included
-in the ``videodevX`` patch was fixed. Users of an earlier version of
-``videodevX`` on Linux 2.4.0 should recompile their V4L and V4L2
-drivers.
-
-2001-01-26: A possible kernel-level incompatibility between the
-``videodev.h`` file in the ``videodevX`` patch and the ``videodev.h``
-file in Linux 2.2.x with devfs patches applied was fixed.
-
-2001-03-02: Certain V4L ioctls which pass data in both direction
-although they are defined with read-only parameter, did not work
-correctly through the backward compatibility layer. [Solution?]
-
-2001-04-13: Big endian 16-bit RGB formats were added.
-
-2001-09-17: New YUV formats and the
-:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctls were added.
-(The old ``VIDIOC_G_FREQ`` and ``VIDIOC_S_FREQ`` ioctls did not take
-multiple tuners into account.)
-
-2000-09-18: ``V4L2_BUF_TYPE_VBI`` was added. This may *break
-compatibility* as the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls may fail now if the struct
-struct ``v4l2_fmt`` ``type`` field does not contain
-``V4L2_BUF_TYPE_VBI``. In the documentation of the struct
-:c:type:`v4l2_vbi_format` ``offset`` field the
-ambiguous phrase "rising edge" was changed to "leading edge".
-
-
-V4L2 Version 0.20 2000-11-23
-============================
-
-A number of changes were made to the raw VBI interface.
-
-1. Figures clarifying the line numbering scheme were added to the V4L2
-   API specification. The ``start``\ [0] and ``start``\ [1] fields no
-   longer count line numbers beginning at zero. Rationale: a) The
-   previous definition was unclear. b) The ``start``\ [] values are
-   ordinal numbers. c) There is no point in inventing a new line
-   numbering scheme. We now use line number as defined by ITU-R, period.
-   Compatibility: Add one to the start values. Applications depending on
-   the previous semantics may not function correctly.
-
-2. The restriction "count[0] > 0 and count[1] > 0" has been relaxed to
-   "(count[0] + count[1]) > 0". Rationale: Drivers may allocate
-   resources at scan line granularity and some data services are
-   transmitted only on the first field. The comment that both ``count``
-   values will usually be equal is misleading and pointless and has been
-   removed. This change *breaks compatibility* with earlier versions:
-   Drivers may return ``EINVAL``, applications may not function correctly.
-
-3. Drivers are again permitted to return negative (unknown) start values
-   as proposed earlier. Why this feature was dropped is unclear. This
-   change may *break compatibility* with applications depending on the
-   start values being positive. The use of ``EBUSY`` and ``EINVAL``
-   error codes with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl was
-   clarified. The ``EBUSY`` error code was finally documented, and the
-   ``reserved2`` field which was previously mentioned only in the
-   ``videodev.h`` header file.
-
-4. New buffer types ``V4L2_TYPE_VBI_INPUT`` and ``V4L2_TYPE_VBI_OUTPUT``
-   were added. The former is an alias for the old ``V4L2_TYPE_VBI``, the
-   latter was missing in the ``videodev.h`` file.
-
-
-V4L2 Version 0.20 2002-07-25
-============================
-
-Added sliced VBI interface proposal.
-
-
-V4L2 in Linux 2.5.46, 2002-10
-=============================
-
-Around October-November 2002, prior to an announced feature freeze of
-Linux 2.5, the API was revised, drawing from experience with V4L2 0.20.
-This unnamed version was finally merged into Linux 2.5.46.
-
-1.  As specified in :ref:`related`, drivers must make related device
-    functions available under all minor device numbers.
-
-2.  The :ref:`open() <func-open>` function requires access mode
-    ``O_RDWR`` regardless of the device type. All V4L2 drivers
-    exchanging data with applications must support the ``O_NONBLOCK``
-    flag. The ``O_NOIO`` flag, a V4L2 symbol which aliased the
-    meaningless ``O_TRUNC`` to indicate accesses without data exchange
-    (panel applications) was dropped. Drivers must stay in "panel mode"
-    until the application attempts to initiate a data exchange, see
-    :ref:`open`.
-
-3.  The struct :c:type:`v4l2_capability` changed
-    dramatically. Note that also the size of the structure changed,
-    which is encoded in the ioctl request code, thus older V4L2 devices
-    will respond with an ``EINVAL`` error code to the new
-    :ref:`VIDIOC_QUERYCAP` ioctl.
-
-    There are new fields to identify the driver, a new RDS device
-    function ``V4L2_CAP_RDS_CAPTURE``, the ``V4L2_CAP_AUDIO`` flag
-    indicates if the device has any audio connectors, another I/O
-    capability ``V4L2_CAP_ASYNCIO`` can be flagged. In response to these
-    changes the ``type`` field became a bit set and was merged into the
-    ``flags`` field. ``V4L2_FLAG_TUNER`` was renamed to
-    ``V4L2_CAP_TUNER``, ``V4L2_CAP_VIDEO_OVERLAY`` replaced
-    ``V4L2_FLAG_PREVIEW`` and ``V4L2_CAP_VBI_CAPTURE`` and
-    ``V4L2_CAP_VBI_OUTPUT`` replaced ``V4L2_FLAG_DATA_SERVICE``.
-    ``V4L2_FLAG_READ`` and ``V4L2_FLAG_WRITE`` were merged into
-    ``V4L2_CAP_READWRITE``.
-
-    The redundant fields ``inputs``, ``outputs`` and ``audios`` were
-    removed. These properties can be determined as described in
-    :ref:`video` and :ref:`audio`.
-
-    The somewhat volatile and therefore barely useful fields
-    ``maxwidth``, ``maxheight``, ``minwidth``, ``minheight``,
-    ``maxframerate`` were removed. This information is available as
-    described in :ref:`format` and :ref:`standard`.
-
-    ``V4L2_FLAG_SELECT`` was removed. We believe the select() function
-    is important enough to require support of it in all V4L2 drivers
-    exchanging data with applications. The redundant
-    ``V4L2_FLAG_MONOCHROME`` flag was removed, this information is
-    available as described in :ref:`format`.
-
-4.  In struct :c:type:`v4l2_input` the ``assoc_audio``
-    field and the ``capability`` field and its only flag
-    ``V4L2_INPUT_CAP_AUDIO`` was replaced by the new ``audioset`` field.
-    Instead of linking one video input to one audio input this field
-    reports all audio inputs this video input combines with.
-
-    New fields are ``tuner`` (reversing the former link from tuners to
-    video inputs), ``std`` and ``status``.
-
-    Accordingly struct :c:type:`v4l2_output` lost its
-    ``capability`` and ``assoc_audio`` fields. ``audioset``,
-    ``modulator`` and ``std`` where added instead.
-
-5.  The struct :c:type:`v4l2_audio` field ``audio`` was
-    renamed to ``index``, for consistency with other structures. A new
-    capability flag ``V4L2_AUDCAP_STEREO`` was added to indicated if the
-    audio input in question supports stereo sound.
-    ``V4L2_AUDCAP_EFFECTS`` and the corresponding ``V4L2_AUDMODE`` flags
-    where removed. This can be easily implemented using controls.
-    (However the same applies to AVL which is still there.)
-
-    Again for consistency the struct
-    :c:type:`v4l2_audioout` field ``audio`` was renamed
-    to ``index``.
-
-6.  The struct :c:type:`v4l2_tuner` ``input`` field was
-    replaced by an ``index`` field, permitting devices with multiple
-    tuners. The link between video inputs and tuners is now reversed,
-    inputs point to their tuner. The ``std`` substructure became a
-    simple set (more about this below) and moved into struct
-    :c:type:`v4l2_input`. A ``type`` field was added.
-
-    Accordingly in struct :c:type:`v4l2_modulator` the
-    ``output`` was replaced by an ``index`` field.
-
-    In struct :c:type:`v4l2_frequency` the ``port``
-    field was replaced by a ``tuner`` field containing the respective
-    tuner or modulator index number. A tuner ``type`` field was added
-    and the ``reserved`` field became larger for future extensions
-    (satellite tuners in particular).
-
-7.  The idea of completely transparent video standards was dropped.
-    Experience showed that applications must be able to work with video
-    standards beyond presenting the user a menu. Instead of enumerating
-    supported standards with an ioctl applications can now refer to
-    standards by :ref:`v4l2_std_id <v4l2-std-id>` and symbols
-    defined in the ``videodev2.h`` header file. For details see
-    :ref:`standard`. The :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
-    :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` now take a pointer to this
-    type as argument. :ref:`VIDIOC_QUERYSTD` was
-    added to autodetect the received standard, if the hardware has this
-    capability. In struct :c:type:`v4l2_standard` an
-    ``index`` field was added for
-    :ref:`VIDIOC_ENUMSTD`. A
-    :ref:`v4l2_std_id <v4l2-std-id>` field named ``id`` was added as
-    machine readable identifier, also replacing the ``transmission``
-    field. The misleading ``framerate`` field was renamed to
-    ``frameperiod``. The now obsolete ``colorstandard`` information,
-    originally needed to distguish between variations of standards, were
-    removed.
-
-    Struct ``v4l2_enumstd`` ceased to be.
-    :ref:`VIDIOC_ENUMSTD` now takes a pointer to a
-    struct :c:type:`v4l2_standard` directly. The
-    information which standards are supported by a particular video
-    input or output moved into struct :c:type:`v4l2_input`
-    and struct :c:type:`v4l2_output` fields named ``std``,
-    respectively.
-
-8.  The struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` fields
-    ``category`` and ``group`` did not catch on and/or were not
-    implemented as expected and therefore removed.
-
-9.  The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl was added to
-    negotiate data formats as with
-    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, but without the overhead of
-    programming the hardware and regardless of I/O in progress.
-
-    In struct :c:type:`v4l2_format` the ``fmt`` union was
-    extended to contain struct :c:type:`v4l2_window`. All
-    image format negotiations are now possible with ``VIDIOC_G_FMT``,
-    ``VIDIOC_S_FMT`` and ``VIDIOC_TRY_FMT``; ioctl. The ``VIDIOC_G_WIN``
-    and ``VIDIOC_S_WIN`` ioctls to prepare for a video overlay were
-    removed. The ``type`` field changed to type enum
-    :c:type:`v4l2_buf_type` and the buffer type names
-    changed as follows.
-
-
-
-    .. flat-table::
-	:header-rows:  1
-	:stub-columns: 0
-
-	* - Old defines
-	  - enum :c:type:`v4l2_buf_type`
-	* - ``V4L2_BUF_TYPE_CAPTURE``
-	  - ``V4L2_BUF_TYPE_VIDEO_CAPTURE``
-	* - ``V4L2_BUF_TYPE_CODECIN``
-	  - Omitted for now
-	* - ``V4L2_BUF_TYPE_CODECOUT``
-	  - Omitted for now
-	* - ``V4L2_BUF_TYPE_EFFECTSIN``
-	  - Omitted for now
-	* - ``V4L2_BUF_TYPE_EFFECTSIN2``
-	  - Omitted for now
-	* - ``V4L2_BUF_TYPE_EFFECTSOUT``
-	  - Omitted for now
-	* - ``V4L2_BUF_TYPE_VIDEOOUT``
-	  - ``V4L2_BUF_TYPE_VIDEO_OUTPUT``
-	* - ``-``
-	  - ``V4L2_BUF_TYPE_VIDEO_OVERLAY``
-	* - ``-``
-	  - ``V4L2_BUF_TYPE_VBI_CAPTURE``
-	* - ``-``
-	  - ``V4L2_BUF_TYPE_VBI_OUTPUT``
-	* - ``-``
-	  - ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE``
-	* - ``-``
-	  - ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``
-	* - ``V4L2_BUF_TYPE_PRIVATE_BASE``
-	  - ``V4L2_BUF_TYPE_PRIVATE`` (but this is deprecated)
-
-
-10. In struct :c:type:`v4l2_fmtdesc` a enum
-    :c:type:`v4l2_buf_type` field named ``type`` was
-    added as in struct :c:type:`v4l2_format`. The
-    ``VIDIOC_ENUM_FBUFFMT`` ioctl is no longer needed and was removed.
-    These calls can be replaced by
-    :ref:`VIDIOC_ENUM_FMT` with type
-    ``V4L2_BUF_TYPE_VIDEO_OVERLAY``.
-
-11. In struct :c:type:`v4l2_pix_format` the ``depth``
-    field was removed, assuming applications which recognize the format
-    by its four-character-code already know the color depth, and others
-    do not care about it. The same rationale lead to the removal of the
-    ``V4L2_FMT_FLAG_COMPRESSED`` flag. The
-    ``V4L2_FMT_FLAG_SWCONVECOMPRESSED`` flag was removed because drivers
-    are not supposed to convert images in kernel space. A user library
-    of conversion functions should be provided instead. The
-    ``V4L2_FMT_FLAG_BYTESPERLINE`` flag was redundant. Applications can
-    set the ``bytesperline`` field to zero to get a reasonable default.
-    Since the remaining flags were replaced as well, the ``flags`` field
-    itself was removed.
-
-    The interlace flags were replaced by a enum
-    :c:type:`v4l2_field` value in a newly added ``field``
-    field.
-
-
-
-    .. flat-table::
-	:header-rows:  1
-	:stub-columns: 0
-
-	* - Old flag
-	  - enum :c:type:`v4l2_field`
-	* - ``V4L2_FMT_FLAG_NOT_INTERLACED``
-	  - ?
-	* - ``V4L2_FMT_FLAG_INTERLACED`` = ``V4L2_FMT_FLAG_COMBINED``
-	  - ``V4L2_FIELD_INTERLACED``
-	* - ``V4L2_FMT_FLAG_TOPFIELD`` = ``V4L2_FMT_FLAG_ODDFIELD``

-	* - ``-``
-	  - ``V4L2_FIELD_SEQ_BT``
-	* - ``-``
-	  - ``V4L2_FIELD_ALTERNATE``
-
-
-    The color space flags were replaced by a enum
-    :c:type:`v4l2_colorspace` value in a newly added
-    ``colorspace`` field, where one of ``V4L2_COLORSPACE_SMPTE170M``,
-    ``V4L2_COLORSPACE_BT878``, ``V4L2_COLORSPACE_470_SYSTEM_M`` or
-    ``V4L2_COLORSPACE_470_SYSTEM_BG`` replaces ``V4L2_FMT_CS_601YUV``.
-
-12. In struct :c:type:`v4l2_requestbuffers` the
-    ``type`` field was properly defined as enum
-    :c:type:`v4l2_buf_type`. Buffer types changed as
-    mentioned above. A new ``memory`` field of type enum
-    :c:type:`v4l2_memory` was added to distinguish between
-    I/O methods using buffers allocated by the driver or the
-    application. See :ref:`io` for details.
-
-13. In struct :c:type:`v4l2_buffer` the ``type`` field was
-    properly defined as enum :c:type:`v4l2_buf_type`.
-    Buffer types changed as mentioned above. A ``field`` field of type
-    enum :c:type:`v4l2_field` was added to indicate if a
-    buffer contains a top or bottom field. The old field flags were
-    removed. Since no unadjusted system time clock was added to the
-    kernel as planned, the ``timestamp`` field changed back from type
-    stamp_t, an unsigned 64 bit integer expressing the sample time in
-    nanoseconds, to struct :c:type:`timeval`. With the addition
-    of a second memory mapping method the ``offset`` field moved into
-    union ``m``, and a new ``memory`` field of type enum
-    :c:type:`v4l2_memory` was added to distinguish between
-    I/O methods. See :ref:`io` for details.
-
-    The ``V4L2_BUF_REQ_CONTIG`` flag was used by the V4L compatibility
-    layer, after changes to this code it was no longer needed. The
-    ``V4L2_BUF_ATTR_DEVICEMEM`` flag would indicate if the buffer was
-    indeed allocated in device memory rather than DMA-able system
-    memory. It was barely useful and so was removed.
-
-14. In struct :c:type:`v4l2_framebuffer` the
-    ``base[3]`` array anticipating double- and triple-buffering in
-    off-screen video memory, however without defining a synchronization
-    mechanism, was replaced by a single pointer. The
-    ``V4L2_FBUF_CAP_SCALEUP`` and ``V4L2_FBUF_CAP_SCALEDOWN`` flags were
-    removed. Applications can determine this capability more accurately
-    using the new cropping and scaling interface. The
-    ``V4L2_FBUF_CAP_CLIPPING`` flag was replaced by
-    ``V4L2_FBUF_CAP_LIST_CLIPPING`` and
-    ``V4L2_FBUF_CAP_BITMAP_CLIPPING``.
-
-15. In struct :c:type:`v4l2_clip` the ``x``, ``y``,
-    ``width`` and ``height`` field moved into a ``c`` substructure of
-    type struct :c:type:`v4l2_rect`. The ``x`` and ``y``
-    fields were renamed to ``left`` and ``top``, i. e. offsets to a
-    context dependent origin.
-
-16. In struct :c:type:`v4l2_window` the ``x``, ``y``,
-    ``width`` and ``height`` field moved into a ``w`` substructure as
-    above. A ``field`` field of type :c:type:`v4l2_field` was added to
-    distinguish between field and frame (interlaced) overlay.
-
-17. The digital zoom interface, including struct
-    struct ``v4l2_zoomcap``, struct
-    struct ``v4l2_zoom``, ``V4L2_ZOOM_NONCAP`` and
-    ``V4L2_ZOOM_WHILESTREAMING`` was replaced by a new cropping and
-    scaling interface. The previously unused struct
-    struct :c:type:`v4l2_cropcap` and struct :c:type:`v4l2_crop`
-    where redefined for this purpose. See :ref:`crop` for details.
-
-18. In struct :c:type:`v4l2_vbi_format` the
-    ``SAMPLE_FORMAT`` field now contains a four-character-code as used
-    to identify video image formats and ``V4L2_PIX_FMT_GREY`` replaces
-    the ``V4L2_VBI_SF_UBYTE`` define. The ``reserved`` field was
-    extended.
-
-19. In struct :c:type:`v4l2_captureparm` the type of
-    the ``timeperframe`` field changed from unsigned long to struct
-    :c:type:`v4l2_fract`. This allows the accurate
-    expression of multiples of the NTSC-M frame rate 30000 / 1001. A new
-    field ``readbuffers`` was added to control the driver behaviour in
-    read I/O mode.
-
-    Similar changes were made to struct
-    :c:type:`v4l2_outputparm`.
-
-20. The struct ``v4l2_performance`` and
-    ``VIDIOC_G_PERF`` ioctl were dropped. Except when using the
-    :ref:`read/write I/O method <rw>`, which is limited anyway, this
-    information is already available to applications.
-
-21. The example transformation from RGB to YCbCr color space in the old
-    V4L2 documentation was inaccurate, this has been corrected in
-    :ref:`pixfmt`.
-
-
-V4L2 2003-06-19
-===============
-
-1. A new capability flag ``V4L2_CAP_RADIO`` was added for radio devices.
-   Prior to this change radio devices would identify solely by having
-   exactly one tuner whose type field reads ``V4L2_TUNER_RADIO``.
-
-2. An optional driver access priority mechanism was added, see
-   :ref:`app-pri` for details.
-
-3. The audio input and output interface was found to be incomplete.
-
-   Previously the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl would
-   enumerate the available audio inputs. An ioctl to determine the
-   current audio input, if more than one combines with the current video
-   input, did not exist. So ``VIDIOC_G_AUDIO`` was renamed to
-   ``VIDIOC_G_AUDIO_OLD``, this ioctl was removed on Kernel 2.6.39. The
-   :ref:`VIDIOC_ENUMAUDIO` ioctl was added to
-   enumerate audio inputs, while
-   :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` now reports the current
-   audio input.
-
-   The same changes were made to
-   :ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` and
-   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>`.
-
-   Until further the "videodev" module will automatically translate
-   between the old and new ioctls, but drivers and applications must be
-   updated to successfully compile again.
-
-4. The :ref:`VIDIOC_OVERLAY` ioctl was incorrectly
-   defined with write-read parameter. It was changed to write-only,
-   while the write-read version was renamed to ``VIDIOC_OVERLAY_OLD``.
-   The old ioctl was removed on Kernel 2.6.39. Until further the
-   "videodev" kernel module will automatically translate to the new
-   version, so drivers must be recompiled, but not applications.
-
-5. :ref:`overlay` incorrectly stated that clipping rectangles define
-   regions where the video can be seen. Correct is that clipping
-   rectangles define regions where *no* video shall be displayed and so
-   the graphics surface can be seen.
-
-6. The :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` and
-   :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls were defined with
-   write-only parameter, inconsistent with other ioctls modifying their
-   argument. They were changed to write-read, while a ``_OLD`` suffix
-   was added to the write-only versions. The old ioctls were removed on
-   Kernel 2.6.39. Drivers and applications assuming a constant parameter
-   need an update.
-
-
-V4L2 2003-11-05
-===============
-
-1. In :ref:`pixfmt-rgb` the following pixel formats were incorrectly
-   transferred from Bill Dirks' V4L2 specification. Descriptions below
-   refer to bytes in memory, in ascending address order.
-
-
-
-   .. flat-table::

-   The ``V4L2_PIX_FMT_BGR24`` example was always correct.
-
-   In :ref:`v4l-image-properties` the mapping of the V4L
-   ``VIDEO_PALETTE_RGB24`` and ``VIDEO_PALETTE_RGB32`` formats to V4L2
-   pixel formats was accordingly corrected.
-
-2. Unrelated to the fixes above, drivers may still interpret some V4L2
-   RGB pixel formats differently. These issues have yet to be addressed,
-   for details see :ref:`pixfmt-rgb`.
-
-
-V4L2 in Linux 2.6.6, 2004-05-09
-===============================
-
-1. The :ref:`VIDIOC_CROPCAP` ioctl was incorrectly
-   defined with read-only parameter. It is now defined as write-read
-   ioctl, while the read-only version was renamed to
-   ``VIDIOC_CROPCAP_OLD``. The old ioctl was removed on Kernel 2.6.39.
-
-
-V4L2 in Linux 2.6.8
-===================
-
-1. A new field ``input`` (former ``reserved[0]``) was added to the
-   struct :c:type:`v4l2_buffer` structure. Purpose of this
-   field is to alternate between video inputs (e. g. cameras) in step
-   with the video capturing process. This function must be enabled with
-   the new ``V4L2_BUF_FLAG_INPUT`` flag. The ``flags`` field is no
-   longer read-only.
-
-
-V4L2 spec erratum 2004-08-01
-============================
-
-1. The return value of the :ref:`func-open` function was incorrectly
-   documented.
-
-2. Audio output ioctls end in -AUDOUT, not -AUDIOOUT.
-
-3. In the Current Audio Input example the ``VIDIOC_G_AUDIO`` ioctl took
-   the wrong argument.
-
-4. The documentation of the :ref:`VIDIOC_QBUF` and
-   :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctls did not mention the
-   struct :c:type:`v4l2_buffer` ``memory`` field. It was
-   also missing from examples. Also on the ``VIDIOC_DQBUF`` page the ``EIO``
-   error code was not documented.
-
-
-V4L2 in Linux 2.6.14
-====================
-
-1. A new sliced VBI interface was added. It is documented in
-   :ref:`sliced` and replaces the interface first proposed in V4L2
-   specification 0.8.
-
-
-V4L2 in Linux 2.6.15
-====================
-
-1. The :ref:`VIDIOC_LOG_STATUS` ioctl was added.
-
-2. New video standards ``V4L2_STD_NTSC_443``, ``V4L2_STD_SECAM_LC``,
-   ``V4L2_STD_SECAM_DK`` (a set of SECAM D, K and K1), and
-   ``V4L2_STD_ATSC`` (a set of ``V4L2_STD_ATSC_8_VSB`` and
-   ``V4L2_STD_ATSC_16_VSB``) were defined. Note the ``V4L2_STD_525_60``
-   set now includes ``V4L2_STD_NTSC_443``. See also
-   :ref:`v4l2-std-id`.
-
-3. The ``VIDIOC_G_COMP`` and ``VIDIOC_S_COMP`` ioctl were renamed to
-   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` respectively. Their
-   argument was replaced by a struct
-   ``v4l2_mpeg_compression`` pointer. (The
-   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls where removed
-   in Linux 2.6.25.)
-
-
-V4L2 spec erratum 2005-11-27
-============================
-
-The capture example in :ref:`capture-example` called the
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl without checking if
-cropping is supported. In the video standard selection example in
-:ref:`standard` the :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` call used
-the wrong argument type.
-
-
-V4L2 spec erratum 2006-01-10
-============================
-
-1. The ``V4L2_IN_ST_COLOR_KILL`` flag in struct
-   :c:type:`v4l2_input` not only indicates if the color
-   killer is enabled, but also if it is active. (The color killer
-   disables color decoding when it detects no color in the video signal
-   to improve the image quality.)
-
-2. :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` is a write-read ioctl, not
-   write-only as stated on its reference page. The ioctl changed in 2003
-   as noted above.
-
-
-V4L2 spec erratum 2006-02-03
-============================
-
-1. In struct :c:type:`v4l2_captureparm` and struct
-   :c:type:`v4l2_outputparm` the ``timeperframe``
-   field gives the time in seconds, not microseconds.
-
-
-V4L2 spec erratum 2006-02-04
-============================
-
-1. The ``clips`` field in struct :c:type:`v4l2_window`
-   must point to an array of struct :c:type:`v4l2_clip`, not
-   a linked list, because drivers ignore the struct
-   struct :c:type:`v4l2_clip`. ``next`` pointer.
-
-
-V4L2 in Linux 2.6.17
-====================
-
-1. New video standard macros were added: ``V4L2_STD_NTSC_M_KR`` (NTSC M
-   South Korea), and the sets ``V4L2_STD_MN``, ``V4L2_STD_B``,
-   ``V4L2_STD_GH`` and ``V4L2_STD_DK``. The ``V4L2_STD_NTSC`` and
-   ``V4L2_STD_SECAM`` sets now include ``V4L2_STD_NTSC_M_KR`` and
-   ``V4L2_STD_SECAM_LC`` respectively.
-
-2. A new ``V4L2_TUNER_MODE_LANG1_LANG2`` was defined to record both
-   languages of a bilingual program. The use of
-   ``V4L2_TUNER_MODE_STEREO`` for this purpose is deprecated now. See
-   the :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` section for details.
-
-
-V4L2 spec erratum 2006-09-23 (Draft 0.15)
-=========================================
-
-1. In various places ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` and
-   ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT`` of the sliced VBI interface were
-   not mentioned along with other buffer types.
-
-2. In :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` it was clarified that the struct
-   :c:type:`v4l2_audio` ``mode`` field is a flags field.
-
-3. :ref:`VIDIOC_QUERYCAP` did not mention the sliced VBI and radio
-   capability flags.
-
-4. In :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` it was clarified that applications
-   must initialize the tuner ``type`` field of struct
-   :c:type:`v4l2_frequency` before calling
-   :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`.
-
-5. The ``reserved`` array in struct
-   :c:type:`v4l2_requestbuffers` has 2 elements,
-   not 32.
-
-6. In :ref:`output` and :ref:`raw-vbi` the device file names
-   ``/dev/vout`` which never caught on were replaced by ``/dev/video``.
-
-7. With Linux 2.6.15 the possible range for VBI device minor numbers was
-   extended from 224-239 to 224-255. Accordingly device file names
-   ``/dev/vbi0`` to ``/dev/vbi31`` are possible now.
-
-
-V4L2 in Linux 2.6.18
-====================
-
-1. New ioctls :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-   :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-   :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` were added, a
-   flag to skip unsupported controls with
-   :ref:`VIDIOC_QUERYCTRL`, new control types
-   ``V4L2_CTRL_TYPE_INTEGER64`` and ``V4L2_CTRL_TYPE_CTRL_CLASS``
-   (:c:type:`v4l2_ctrl_type`), and new control flags
-   ``V4L2_CTRL_FLAG_READ_ONLY``, ``V4L2_CTRL_FLAG_UPDATE``,
-   ``V4L2_CTRL_FLAG_INACTIVE`` and ``V4L2_CTRL_FLAG_SLIDER``
-   (:ref:`control-flags`). See :ref:`extended-controls` for details.
-
-
-V4L2 in Linux 2.6.19
-====================
-
-1. In struct :c:type:`v4l2_sliced_vbi_cap` a
-   buffer type field was added replacing a reserved field. Note on
-   architectures where the size of enum types differs from int types the
-   size of the structure changed. The
-   :ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl
-   was redefined from being read-only to write-read. Applications must
-   initialize the type field and clear the reserved fields now. These
-   changes may *break the compatibility* with older drivers and
-   applications.
-
-2. The ioctls :ref:`VIDIOC_ENUM_FRAMESIZES`
-   and
-   :ref:`VIDIOC_ENUM_FRAMEINTERVALS`
-   were added.
-
-3. A new pixel format ``V4L2_PIX_FMT_RGB444`` (:ref:`pixfmt-rgb`) was
-   added.
-
-
-V4L2 spec erratum 2006-10-12 (Draft 0.17)
-=========================================
-
-1. ``V4L2_PIX_FMT_HM12`` (:ref:`reserved-formats`) is a YUV 4:2:0, not
-   4:2:2 format.
-
-
-V4L2 in Linux 2.6.21
-====================
-
-1. The ``videodev2.h`` header file is now dual licensed under GNU
-   General Public License version two or later, and under a 3-clause
-   BSD-style license.
-
-
-V4L2 in Linux 2.6.22
-====================
-
-1. Two new field orders ``V4L2_FIELD_INTERLACED_TB`` and
-   ``V4L2_FIELD_INTERLACED_BT`` were added. See :c:type:`v4l2_field` for
-   details.
-
-2. Three new clipping/blending methods with a global or straight or
-   inverted local alpha value were added to the video overlay interface.
-   See the description of the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-   and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls for details.
-
-   A new ``global_alpha`` field was added to
-   :c:type:`v4l2_window`, extending the structure. This
-   may *break compatibility* with applications using a struct
-   struct :c:type:`v4l2_window` directly. However the
-   :ref:`VIDIOC_G/S/TRY_FMT <VIDIOC_G_FMT>` ioctls, which take a
-   pointer to a :c:type:`v4l2_format` parent structure
-   with padding bytes at the end, are not affected.
-
-3. The format of the ``chromakey`` field in struct
-   :c:type:`v4l2_window` changed from "host order RGB32"
-   to a pixel value in the same format as the framebuffer. This may
-   *break compatibility* with existing applications. Drivers supporting
-   the "host order RGB32" format are not known.
-
-
-V4L2 in Linux 2.6.24
-====================
-
-1. The pixel formats ``V4L2_PIX_FMT_PAL8``, ``V4L2_PIX_FMT_YUV444``,
-   ``V4L2_PIX_FMT_YUV555``, ``V4L2_PIX_FMT_YUV565`` and
-   ``V4L2_PIX_FMT_YUV32`` were added.
-
-
-V4L2 in Linux 2.6.25
-====================
-
-1. The pixel formats :ref:`V4L2_PIX_FMT_Y16 <V4L2-PIX-FMT-Y16>` and
-   :ref:`V4L2_PIX_FMT_SBGGR16 <V4L2-PIX-FMT-SBGGR16>` were added.
-
-2. New :ref:`controls <control>` ``V4L2_CID_POWER_LINE_FREQUENCY``,
-   ``V4L2_CID_HUE_AUTO``, ``V4L2_CID_WHITE_BALANCE_TEMPERATURE``,
-   ``V4L2_CID_SHARPNESS`` and ``V4L2_CID_BACKLIGHT_COMPENSATION`` were
-   added. The controls ``V4L2_CID_BLACK_LEVEL``, ``V4L2_CID_WHITENESS``,
-   ``V4L2_CID_HCENTER`` and ``V4L2_CID_VCENTER`` were deprecated.
-
-3. A :ref:`Camera controls class <camera-controls>` was added, with
-   the new controls ``V4L2_CID_EXPOSURE_AUTO``,
-   ``V4L2_CID_EXPOSURE_ABSOLUTE``, ``V4L2_CID_EXPOSURE_AUTO_PRIORITY``,
-   ``V4L2_CID_PAN_RELATIVE``, ``V4L2_CID_TILT_RELATIVE``,
-   ``V4L2_CID_PAN_RESET``, ``V4L2_CID_TILT_RESET``,
-   ``V4L2_CID_PAN_ABSOLUTE``, ``V4L2_CID_TILT_ABSOLUTE``,
-   ``V4L2_CID_FOCUS_ABSOLUTE``, ``V4L2_CID_FOCUS_RELATIVE`` and
-   ``V4L2_CID_FOCUS_AUTO``.
-
-4. The ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls, which
-   were superseded by the :ref:`extended controls <extended-controls>`
-   interface in Linux 2.6.18, where finally removed from the
-   ``videodev2.h`` header file.
-
-
-V4L2 in Linux 2.6.26
-====================
-
-1. The pixel formats ``V4L2_PIX_FMT_Y16`` and ``V4L2_PIX_FMT_SBGGR16``
-   were added.
-
-2. Added user controls ``V4L2_CID_CHROMA_AGC`` and
-   ``V4L2_CID_COLOR_KILLER``.
-
-
-V4L2 in Linux 2.6.27
-====================
-
-1. The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl
-   and the ``V4L2_CAP_HW_FREQ_SEEK`` capability were added.
-
-2. The pixel formats ``V4L2_PIX_FMT_YVYU``, ``V4L2_PIX_FMT_PCA501``,
-   ``V4L2_PIX_FMT_PCA505``, ``V4L2_PIX_FMT_PCA508``,
-   ``V4L2_PIX_FMT_PCA561``, ``V4L2_PIX_FMT_SGBRG8``,
-   ``V4L2_PIX_FMT_PAC207`` and ``V4L2_PIX_FMT_PJPG`` were added.
-
-
-V4L2 in Linux 2.6.28

-
-.. _other:
-
-Relation of V4L2 to other Linux multimedia APIs
-===============================================
-
-
-.. _xvideo:
-
-X Video Extension
------------------
-
-The X Video Extension (abbreviated XVideo or just Xv) is an extension of
-the X Window system, implemented for example by the XFree86 project. Its
-scope is similar to V4L2, an API to video capture and output devices for
-X clients. Xv allows applications to display live video in a window,
-send window contents to a TV output, and capture or output still images
-in XPixmaps [#f1]_. With their implementation XFree86 makes the extension
-available across many operating systems and architectures.
-
-Because the driver is embedded into the X server Xv has a number of
-advantages over the V4L2 :ref:`video overlay interface <overlay>`. The
-driver can easily determine the overlay target, i. e. visible graphics
-memory or off-screen buffers for a destructive overlay. It can program
-the RAMDAC for a non-destructive overlay, scaling or color-keying, or
-the clipping functions of the video capture hardware, always in sync
-with drawing operations or windows moving or changing their stacking
-order.
-
-To combine the advantages of Xv and V4L a special Xv driver exists in
-XFree86 and XOrg, just programming any overlay capable Video4Linux
-device it finds. To enable it ``/etc/X11/XF86Config`` must contain these
-lines:
-
-::
-
-    Section "Module"
-	Load "v4l"
-    EndSection
-
-As of XFree86 4.2 this driver still supports only V4L ioctls, however it
-should work just fine with all V4L2 devices through the V4L2
-backward-compatibility layer. Since V4L2 permits multiple opens it is
-possible (if supported by the V4L2 driver) to capture video while an X
-client requested video overlay. Restrictions of simultaneous capturing
-and overlay are discussed in :ref:`overlay` apply.
-
-Only marginally related to V4L2, XFree86 extended Xv to support hardware
-YUV to RGB conversion and scaling for faster video playback, and added
-an interface to MPEG-2 decoding hardware. This API is useful to display
-images captured with V4L2 devices.
-
-
-Digital Video
--------------
-
-V4L2 does not support digital terrestrial, cable or satellite broadcast.
-A separate project aiming at digital receivers exists. You can find its
-homepage at `https://linuxtv.org <https://linuxtv.org>`__. The Linux
-DVB API has no connection to the V4L2 API except that drivers for hybrid
-hardware may support both.

-############
-Input/Output
-############
-The V4L2 API defines several different methods to read from or write to
-a device. All drivers exchanging data with applications must support at
-least one of them.
-
-The classic I/O method using the :ref:`read() <func-read>` and
-:ref:`write() <func-write>` function is automatically selected after opening a
-V4L2 device. When the driver does not support this method attempts to
-read or write will fail at any time.
-
-Other methods must be negotiated. To select the streaming I/O method
-with memory mapped or user buffers applications call the
-:ref:`VIDIOC_REQBUFS` ioctl. The asynchronous I/O
-method is not defined yet.
-
-Video overlay can be considered another I/O method, although the
-application does not directly receive the image data. It is selected by
-initiating video overlay with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl. For more information see :ref:`overlay`.
-
-Generally exactly one I/O method, including overlay, is associated with
-each file descriptor. The only exceptions are applications not
-exchanging data with a driver ("panel applications", see :ref:`open`)
-and drivers permitting simultaneous video capturing and overlay using
-the same file descriptor, for compatibility with V4L and earlier
-versions of V4L2.
-
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_REQBUFS` would permit this to some
-degree, but for simplicity drivers need not support switching the I/O

-Introduction
-************
-
-libv4l is a collection of libraries which adds a thin abstraction layer
-on top of video4linux2 devices. The purpose of this (thin) layer is to
-make it easy for application writers to support a wide variety of
-devices without having to write separate code for different devices in
-the same class.
-
-An example of using libv4l is provided by
-:ref:`v4l2grab <v4l2grab-example>`.
-
-libv4l consists of 3 different libraries:
-
-
-libv4lconvert
-=============
-
-libv4lconvert is a library that converts several different pixelformats
-found in V4L2 drivers into a few common RGB and YUY formats.
-
-It currently accepts the following V4L2 driver formats:
-:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
-:ref:`V4L2_PIX_FMT_HM12 <V4L2-PIX-FMT-HM12>`,
-:ref:`V4L2_PIX_FMT_JPEG <V4L2-PIX-FMT-JPEG>`,
-:ref:`V4L2_PIX_FMT_MJPEG <V4L2-PIX-FMT-MJPEG>`,
-:ref:`V4L2_PIX_FMT_MR97310A <V4L2-PIX-FMT-MR97310A>`,
-:ref:`V4L2_PIX_FMT_OV511 <V4L2-PIX-FMT-OV511>`,
-:ref:`V4L2_PIX_FMT_OV518 <V4L2-PIX-FMT-OV518>`,
-:ref:`V4L2_PIX_FMT_PAC207 <V4L2-PIX-FMT-PAC207>`,
-:ref:`V4L2_PIX_FMT_PJPG <V4L2-PIX-FMT-PJPG>`,
-:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
-:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`,
-:ref:`V4L2_PIX_FMT_SGBRG8 <V4L2-PIX-FMT-SGBRG8>`,
-:ref:`V4L2_PIX_FMT_SGRBG8 <V4L2-PIX-FMT-SGRBG8>`,
-:ref:`V4L2_PIX_FMT_SN9C10X <V4L2-PIX-FMT-SN9C10X>`,
-:ref:`V4L2_PIX_FMT_SN9C20X_I420 <V4L2-PIX-FMT-SN9C20X-I420>`,
-:ref:`V4L2_PIX_FMT_SPCA501 <V4L2-PIX-FMT-SPCA501>`,
-:ref:`V4L2_PIX_FMT_SPCA505 <V4L2-PIX-FMT-SPCA505>`,
-:ref:`V4L2_PIX_FMT_SPCA508 <V4L2-PIX-FMT-SPCA508>`,
-:ref:`V4L2_PIX_FMT_SPCA561 <V4L2-PIX-FMT-SPCA561>`,
-:ref:`V4L2_PIX_FMT_SQ905C <V4L2-PIX-FMT-SQ905C>`,
-:ref:`V4L2_PIX_FMT_SRGGB8 <V4L2-PIX-FMT-SRGGB8>`,
-:ref:`V4L2_PIX_FMT_UYVY <V4L2-PIX-FMT-UYVY>`,
-:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`,
-:ref:`V4L2_PIX_FMT_YUYV <V4L2-PIX-FMT-YUYV>`,
-:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, and
-:ref:`V4L2_PIX_FMT_YVYU <V4L2-PIX-FMT-YVYU>`.
-
-Later on libv4lconvert was expanded to also be able to do various video
-processing functions to improve webcam video quality. The video
-processing is split in to 2 parts: libv4lconvert/control and
-libv4lconvert/processing.
-
-The control part is used to offer video controls which can be used to
-control the video processing functions made available by
-libv4lconvert/processing. These controls are stored application wide
-(until reboot) by using a persistent shared memory object.
-
-libv4lconvert/processing offers the actual video processing
-functionality.
-
-
-libv4l1
-=======
-
-This library offers functions that can be used to quickly make v4l1
-applications work with v4l2 devices. These functions work exactly like
-the normal open/close/etc, except that libv4l1 does full emulation of
-the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it will
-just pass calls through.
-
-Since those functions are emulations of the old V4L1 API, it shouldn't
-be used for new applications.
-
-
-libv4l2
-=======
-
-This library should be used for all modern V4L2 applications.
-
-It provides handles to call V4L2 open/ioctl/close/poll methods. Instead
-of just providing the raw output of the device, it enhances the calls in
-the sense that it will use libv4lconvert to provide more video formats
-and to enhance the image quality.
-
-In most cases, libv4l2 just passes the calls directly through to the
-v4l2 driver, intercepting the calls to
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_ENUM_FRAMESIZES <VIDIOC_ENUM_FRAMESIZES>` and
-:ref:`VIDIOC_ENUM_FRAMEINTERVALS <VIDIOC_ENUM_FRAMEINTERVALS>` in
-order to emulate the formats
-:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
-:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
-:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`, and
-:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, if they aren't
-available in the driver. :ref:`VIDIOC_ENUM_FMT <VIDIOC_ENUM_FMT>`
-keeps enumerating the hardware supported formats, plus the emulated
-formats offered by libv4l at the end.
-
-
-.. _libv4l-ops:
-
-Libv4l device control functions
--------------------------------
-
-The common file operation methods are provided by libv4l.
-
-Those functions operate just like the gcc function ``dup()`` and
-V4L2 functions
-:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
-:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`read() <v4l2-read>`,
-:c:func:`mmap() <v4l2-mmap>` and :c:func:`munmap() <v4l2-munmap>`:
-
-.. c:function:: int v4l2_open(const char *file, int oflag, ...)
-
-   operates like the :c:func:`open() <v4l2-open>` function.
-
-.. c:function:: int v4l2_close(int fd)
-
-   operates like the :c:func:`close() <v4l2-close>` function.
-
-.. c:function:: int v4l2_dup(int fd)
-
-   operates like the libc ``dup()`` function, duplicating a file handler.
-
-.. c:function:: int v4l2_ioctl (int fd, unsigned long int request, ...)
-
-   operates like the :c:func:`ioctl() <v4l2-ioctl>` function.
-
-.. c:function:: int v4l2_read (int fd, void* buffer, size_t n)
-
-   operates like the :c:func:`read() <v4l2-read>` function.
-
-.. c:function:: void v4l2_mmap(void *start, size_t length, int prot, int flags, int fd, int64_t offset);
-
-   operates like the :c:func:`munmap() <v4l2-munmap>` function.
-

-
-Those functions provide additional control:
-
-.. c:function:: int v4l2_fd_open(int fd, int v4l2_flags)
-
-   opens an already opened fd for further use through v4l2lib and possibly
-   modify libv4l2's default behavior through the ``v4l2_flags`` argument.
-   Currently, ``v4l2_flags`` can be ``V4L2_DISABLE_CONVERSION``, to disable
-   format conversion.
-
-.. c:function:: int v4l2_set_control(int fd, int cid, int value)
-
-   This function takes a value of 0 - 65535, and then scales that range to the
-   actual range of the given v4l control id, and then if the cid exists and is
-   not locked sets the cid to the scaled value.
-
-.. c:function:: int v4l2_get_control(int fd, int cid)
-
-   This function returns a value of 0 - 65535, scaled to from the actual range
-   of the given v4l control id. when the cid does not exist, could not be
-   accessed for some reason, or some error occurred 0 is returned.

-v4l1compat.so wrapper library
-=============================
-
-This library intercepts calls to
-:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
-:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`mmap() <v4l2-mmap>` and
-:c:func:`munmap() <v4l2-munmap>`
-operations and redirects them to the libv4l counterparts, by using
-``LD_PRELOAD=/usr/lib/v4l1compat.so``. It also emulates V4L1 calls via V4L2
-API.
-
-It allows usage of binary legacy applications that still don't use
-libv4l.

-******************************
-Streaming I/O (Memory Mapping)
-******************************
-
-Input and output devices support this I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set. There are two
-streaming methods, to determine if the memory mapping flavor is
-supported applications must call the :ref:`VIDIOC_REQBUFS` ioctl
-with the memory type set to ``V4L2_MEMORY_MMAP``.
-
-Streaming is an I/O method where only pointers to buffers are exchanged
-between application and driver, the data itself is not copied. Memory
-mapping is primarily intended to map buffers in device memory into the
-application's address space. Device memory can be for example the video
-memory on a graphics card with a video capture add-on. However, being
-the most efficient I/O method available for a long time, many other
-drivers support streaming as well, allocating buffers in DMA-able main
-memory.
-
-A driver can support many sets of buffers. Each set is identified by a
-unique buffer type value. The sets are independent and each set can hold
-a different type of data. To access different sets at the same time
-different file descriptors must be used. [#f1]_
-
-To allocate device buffers applications call the
-:ref:`VIDIOC_REQBUFS` ioctl with the desired number
-of buffers and buffer type, for example ``V4L2_BUF_TYPE_VIDEO_CAPTURE``.
-This ioctl can also be used to change the number of buffers or to free
-the allocated memory, provided none of the buffers are still mapped.
-
-Before applications can access the buffers they must map them into their
-address space with the :ref:`mmap() <func-mmap>` function. The
-location of the buffers in device memory can be determined with the
-:ref:`VIDIOC_QUERYBUF` ioctl. In the single-planar
-API case, the ``m.offset`` and ``length`` returned in a struct
-:c:type:`v4l2_buffer` are passed as sixth and second
-parameter to the :ref:`mmap() <func-mmap>` function. When using the
-multi-planar API, struct :c:type:`v4l2_buffer` contains an
-array of struct :c:type:`v4l2_plane` structures, each
-containing its own ``m.offset`` and ``length``. When using the
-multi-planar API, every plane of every buffer has to be mapped
-separately, so the number of calls to :ref:`mmap() <func-mmap>` should
-be equal to number of buffers times number of planes in each buffer. The
-offset and length values must not be modified. Remember, the buffers are
-allocated in physical memory, as opposed to virtual memory, which can be
-swapped out to disk. Applications should free the buffers as soon as
-possible with the :ref:`munmap() <func-munmap>` function.

-Conceptually streaming drivers maintain two buffer queues, an incoming
-and an outgoing queue. They separate the synchronous capture or output
-operation locked to a video clock from the application which is subject
-to random disk or network delays and preemption by other processes,
-thereby reducing the probability of data loss. The queues are organized
-as FIFOs, buffers will be output in the order enqueued in the incoming
-FIFO, and were captured in the order dequeued from the outgoing FIFO.
-
-The driver may require a minimum number of buffers enqueued at all times
-to function, apart of this no limit exists on the number of buffers
-applications can enqueue in advance, or dequeue and process. They can
-also enqueue in a different order than buffers have been dequeued, and
-the driver can *fill* enqueued *empty* buffers in any order.  [#f2]_ The
-index number of a buffer (struct :c:type:`v4l2_buffer`
-``index``) plays no role here, it only identifies the buffer.
-
-Initially all mapped buffers are in dequeued state, inaccessible by the
-driver. For capturing applications it is customary to first enqueue all
-mapped buffers, then to start capturing and enter the read loop. Here
-the application waits until a filled buffer can be dequeued, and
-re-enqueues the buffer when the data is no longer needed. Output
-applications fill and enqueue buffers, when enough buffers are stacked
-up the output is started with :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`.
-In the write loop, when the application runs out of free buffers, it
-must wait until an empty buffer can be dequeued and reused.
-
-To enqueue and dequeue a buffer applications use the
-:ref:`VIVIOC_QBUF <VIDIOC_QBUF>` and :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
-ioctl. The status of a buffer being mapped, enqueued, full or empty can
-be determined at any time using the :ref:`VIDIOC_QUERYBUF` ioctl. Two
-methods exist to suspend execution of the application until one or more
-buffers can be dequeued.  By default :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
-blocks when no buffer is in the outgoing queue. When the ``O_NONBLOCK``
-flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The :ref:`select() <func-select>`
-or :ref:`poll() <func-poll>` functions are always available.
-
-To start and stop capturing or output applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF
-<VIDIOC_STREAMON>` ioctl.
-
-.. note:::ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-   removes all buffers from both queues as a side effect. Since there is
-   no notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct ::c:type:`v4l2_buffer` ``timestamp`` of captured
-   or outputted buffers.
-
-Drivers implementing memory mapping I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QUERYBUF
-<VIDIOC_QUERYBUF>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the :ref:`mmap()
-<func-mmap>`, :ref:`munmap() <func-munmap>`, :ref:`select()
-<func-select>` and :ref:`poll() <func-poll>` function. [#f3]_
-
-[capture example]
-
-.. [#f1]
-   One could use one file descriptor and set the buffer type field
-   accordingly when calling :ref:`VIDIOC_QBUF` etc.,
-   but it makes the :ref:`select() <func-select>` function ambiguous. We also
-   like the clean approach of one file descriptor per logical stream.
-   Video overlay for example is also a logical stream, although the CPU
-   is not needed for continuous operation.
-
-.. [#f2]
-   Random enqueue order permits applications processing images out of
-   order (such as video codecs) to return buffers earlier, reducing the
-   probability of data loss. Random fill order allows drivers to reuse
-   buffers on a LIFO-basis, taking advantage of caches holding
-   scatter-gather lists and the like.
-
-.. [#f3]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.
-   The rest should be evident.

-***************************
-Opening and Closing Devices
-***************************
-
-
-Device Naming
-=============
-
-V4L2 drivers are implemented as kernel modules, loaded manually by the
-system administrator or automatically when a device is first discovered.
-The driver modules plug into the "videodev" kernel module. It provides
-helper functions and a common application interface specified in this
-document.
-
-Each driver thus loaded registers one or more device nodes with major
-number 81 and a minor number between 0 and 255. Minor numbers are
-allocated dynamically unless the kernel is compiled with the kernel
-option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
-are allocated in ranges depending on the device node type (video, radio,
-etc.).
-
-Many drivers support "video_nr", "radio_nr" or "vbi_nr" module
-options to select specific video/radio/vbi node numbers. This allows the
-user to request that the device node is named e.g. /dev/video5 instead
-of leaving it to chance. When the driver supports multiple devices of
-the same type more than one device node number can be assigned,
-separated by commas:
-
-.. code-block:: none
-
-   # modprobe mydriver video_nr=0,1 radio_nr=0,1
-
-In ``/etc/modules.conf`` this may be written as:
-
-::
-
-    options mydriver video_nr=0,1 radio_nr=0,1
-
-When no device node number is given as module option the driver supplies
-a default.
-
-Normally udev will create the device nodes in /dev automatically for
-you. If udev is not installed, then you need to enable the
-CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to
-correctly relate a minor number to a device node number. I.e., you need
-to be certain that minor number 5 maps to device node name video5. With
-this kernel option different device types have different minor number
-ranges. These ranges are listed in :ref:`devices`.
-
-The creation of character special files (with mknod) is a privileged
-operation and devices cannot be opened by major and minor number. That
-means applications cannot *reliably* scan for loaded or installed
-drivers. The user must enter a device name, or the application can try
-the conventional device names.
-
-
-.. _related:
-
-Related Devices
-===============
-
-Devices can support several functions. For example video capturing, VBI
-capturing and radio support.
-
-The V4L2 API creates different nodes for each of these functions.
-
-The V4L2 API was designed with the idea that one device node could
-support all functions. However, in practice this never worked: this
-'feature' was never used by applications and many drivers did not
-support it and if they did it was certainly never tested. In addition,
-switching a device node between different functions only works when
-using the streaming I/O API, not with the
-:ref:`read() <func-read>`/\ :ref:`write() <func-write>` API.
-
-Today each device node supports just one function.
-
-Besides video input or output the hardware may also support audio
-sampling or playback. If so, these functions are implemented as ALSA PCM
-devices with optional ALSA audio mixer devices.
-
-One problem with all these devices is that the V4L2 API makes no
-provisions to find these related devices. Some really complex devices
-use the Media Controller (see :ref:`media_controller`) which can be
-used for this purpose. But most drivers do not use it, and while some
-code exists that uses sysfs to discover related devices (see
-libmedia_dev in the
-`v4l-utils <http://git.linuxtv.org/cgit.cgi/v4l-utils.git/>`__ git
-repository), there is no library yet that can provide a single API
-towards both Media Controller-based devices and devices that do not use
-the Media Controller. If you want to work on this please write to the
-linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-
-Multiple Opens
-==============
-
-V4L2 devices can be opened more than once. [#f1]_ When this is supported
-by the driver, users can for example start a "panel" application to
-change controls like brightness or audio volume, while another
-application captures video and audio. In other words, panel applications
-are comparable to an ALSA audio mixer application. Just opening a V4L2
-device should not change the state of the device. [#f2]_
-
-Once an application has allocated the memory buffers needed for
-streaming data (by calling the :ref:`VIDIOC_REQBUFS`
-or :ref:`VIDIOC_CREATE_BUFS` ioctls, or
-implicitly by calling the :ref:`read() <func-read>` or
-:ref:`write() <func-write>` functions) that application (filehandle)
-becomes the owner of the device. It is no longer allowed to make changes
-that would affect the buffer sizes (e.g. by calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl) and other applications are
-no longer allowed to allocate buffers or start or stop streaming. The
-EBUSY error code will be returned instead.
-
-Merely opening a V4L2 device does not grant exclusive access. [#f3]_
-Initiating data exchange however assigns the right to read or write the
-requested type of data, and to change related properties, to this file
-descriptor. Applications can request additional access privileges using
-the priority mechanism described in :ref:`app-pri`.
-
-
-Shared Data Streams
-===================
-
-V4L2 drivers should not support multiple applications reading or writing
-the same data stream on a device by copying buffers, time multiplexing
-or similar means. This is better handled by a proxy application in user
-space.
-
-
-Functions
-=========
-
-To open and close V4L2 devices applications use the
-:ref:`open() <func-open>` and :ref:`close() <func-close>` function,
-respectively. Devices are programmed using the
-:ref:`ioctl() <func-ioctl>` function as explained in the following
-sections.
-
-.. [#f1]
-   There are still some old and obscure drivers that have not been
-   updated to allow for multiple opens. This implies that for such
-   drivers :ref:`open() <func-open>` can return an ``EBUSY`` error code
-   when the device is already in use.
-
-.. [#f2]
-   Unfortunately, opening a radio device often switches the state of the
-   device to radio mode in many drivers. This behavior should be fixed
-   eventually as it violates the V4L2 specification.
-
-.. [#f3]
-   Drivers could recognize the ``O_EXCL`` open flag. Presently this is
-   not required, so applications cannot know if it really works.

-**********************
-Standard Image Formats
-**********************
-
-In order to exchange images between drivers and applications, it is
-necessary to have standard image data formats which both sides will
-interpret the same way. V4L2 includes several such formats, and this
-section is intended to be an unambiguous specification of the standard
-image data formats in V4L2.
-
-V4L2 drivers are not limited to these formats, however. Driver-specific
-formats are possible. In that case the application may depend on a codec
-to convert images to one of the standard formats when needed. But the
-data can still be stored and retrieved in the proprietary format. For
-example, a device may support a proprietary compressed format.
-Applications can still capture and save the data in the compressed
-format, saving much disk space, and later use a codec to convert the
-images to the X Windows screen format when the video is to be displayed.
-
-Even so, ultimately, some standard formats are needed, so the V4L2
-specification would not be complete without well-defined standard
-formats.
-
-The V4L2 standard formats are mainly uncompressed formats. The pixels
-are always arranged in memory from left to right, and from top to
-bottom. The first byte of data in the image buffer is always for the
-leftmost pixel of the topmost row. Following that is the pixel
-immediately to its right, and so on until the end of the top row of
-pixels. Following the rightmost pixel of the row there may be zero or
-more bytes of padding to guarantee that each row of pixel data has a
-certain alignment. Following the pad bytes, if any, is data for the
-leftmost pixel of the second row from the top, and so on. The last row
-has just as many pad bytes after it as the other rows.
-
-In V4L2 each format has an identifier which looks like ``PIX_FMT_XXX``,
-defined in the :ref:`videodev2.h <videodev>` header file. These
-identifiers represent
-:ref:`four character (FourCC) codes <v4l2-fourcc>` which are also
-listed below, however they are not the same as those used in the Windows
-world.
-
-For some formats, data is stored in separate, discontiguous memory
-buffers. Those formats are identified by a separate set of FourCC codes
-and are referred to as "multi-planar formats". For example, a
-:ref:`YUV422 <V4L2-PIX-FMT-YUV422M>` frame is normally stored in one
-memory buffer, but it can also be placed in two or three separate
-buffers, with Y component in one buffer and CbCr components in another
-in the 2-planar version or with each component in its own buffer in the
-3-planar case. Those sub-buffers are referred to as "*planes*".

-Infrared 10-bit linked with Depth 16-bit images
-
-
-Description
-===========
-
-Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
-Infrared image followed by Depth data. The pixel definition is 32-bpp,
-with the Depth and Infrared Data split into separate continuous planes of
-identical dimensions.
-
-
-
-The first plane - Infrared data - is stored according to
-:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
-Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
-with values in range 0 to 1023.
-The six remaining MSBs are padded with zeros.
-
-
-The second plane provides 16-bit per-pixel Depth data arranged in
-:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
-
-
-**Frame Structure.**
-Each cell is a 16-bit word with more significant data stored at higher
-memory address (byte order is little-endian).

-
-
-Description
-===========
-
-M420 is a YUV format with ½ horizontal and vertical chroma subsampling
-(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
-Two lines of luma data are followed by one line of chroma data.
-
-The luma plane has one byte per pixel. The chroma plane contains
-interleaved CbCr pixels subsampled by ½ in the horizontal and vertical
-directions. Each CbCr pair belongs to four pixels. For example,
-Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
-Y'\ :sub:`10`, Y'\ :sub:`11`.
-
-All line lengths are identical: if the Y lines include pad bytes so do
-the CbCr lines.
-
-**Byte Order.**

-Intel D4xx UVC Cameras Metadata
-
-
-Description
-===========
-
-Intel D4xx (D435 and other) cameras include per-frame metadata in their UVC
-payload headers, following the Microsoft(R) UVC extension proposal [1_]. That
-means, that the private D4XX metadata, following the standard UVC header, is
-organised in blocks. D4XX cameras implement several standard block types,
-proposed by Microsoft, and several proprietary ones. Supported standard metadata
-types are MetadataId_CaptureStats (ID 3), MetadataId_CameraExtrinsics (ID 4),
-and MetadataId_CameraIntrinsics (ID 5). For their description see [1_]. This
-document describes proprietary metadata types, used by D4xx cameras.
-
-V4L2_META_FMT_D4XX buffers follow the metadata buffer layout of
-V4L2_META_FMT_UVC with the only difference, that it also includes proprietary
-payload header data. D4xx cameras use bulk transfers and only send one payload
-per frame, therefore their headers cannot be larger than 255 bytes.
-
-Below are proprietary Microsoft style metadata types, used by D4xx cameras,
-where all fields are in little endian order:

-3A statistics
-=============
-
-The IPU3 ImgU 3A statistics accelerators collect different statistics over
-an input Bayer frame. Those statistics are obtained from the "ipu3-imgu [01] 3a
-stat" metadata capture video nodes, using the :c:type:`v4l2_meta_format`
-interface. They are formatted as described by the :c:type:`ipu3_uapi_stats_3a`
-structure.
-
-The statistics collected are AWB (Auto-white balance) RGBS (Red, Green, Blue and
-Saturation measure) cells, AWB filter response, AF (Auto-focus) filter response,
-and AE (Auto-exposure) histogram.
-
-The struct :c:type:`ipu3_uapi_4a_config` saves all configurable parameters.

-Pipeline parameters
-===================
-
-The pipeline parameters are passed to the "ipu3-imgu [01] parameters" metadata
-output video nodes, using the :c:type:`v4l2_meta_format` interface. They are
-formatted as described by the :c:type:`ipu3_uapi_params` structure.
-
-Both 3A statistics and pipeline parameters described here are closely tied to
-the underlying camera sub-system (CSS) APIs. They are usually consumed and
-produced by dedicated user space libraries that comprise the important tuning
-tools, thus freeing the developers from being bothered with the low level
-hardware and algorithm details.

-UVC Payload Header Data
-
-
-Description
-===========
-
-This format describes standard UVC metadata, extracted from UVC packet headers
-and provided by the UVC driver through metadata video nodes. That data includes
-exact copies of the standard part of UVC Payload Header contents and auxiliary
-timing information, required for precise interpretation of timestamps, contained
-in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
-the "UVC 1.5 Class specification" for details.
-
-Each UVC payload header can be between 2 and 12 bytes large. Buffers can
-contain multiple headers, if multiple such headers have been transmitted by the
-camera for the respective frame. However, the driver may drop headers when the
-buffer is full, when they contain no useful information (e.g. those without the
-SCR field or with that field identical to the previous header), or generally to
-perform rate limiting when the device sends a large number of headers.
-
-Each individual block contains the following fields:
-
-.. flat-table:: UVC Metadata Block
-    :widths: 1 4
-    :header-rows:  1
-    :stub-columns: 0

-    * - __u16 sof;
-      - USB Frame Number in host byte order, also obtained by the driver as
-        close as possible to the above timestamp to enable correlation between
-        them
-    * - :cspan:`1` *The rest is an exact copy of the UVC payload header:*

-
-
-Description
-===========
-
-This format describes histogram data generated by the Renesas R-Car VSP1 1-D
-Histogram (HGO) engine.
-
-The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
-or HSV data. It operates on a possibly cropped and subsampled input image and
-computes the minimum, maximum and sum of all pixels as well as per-channel
-histograms.
-
-The HGO can compute histograms independently per channel, on the maximum of the
-three channels (RGB data only) or on the Y channel only (YCbCr only). It can
-additionally output the histogram with 64 or 256 bins, resulting in four
-possible modes of operation.
-
-- In *64 bins normal mode*, the HGO operates on the three channels independently
-  to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
-  supported.
-- In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
-  channels to compute a single 64-bins histogram. Only the RGB image format is
-  supported.
-- In *256 bins normal mode*, the HGO operates on the Y channel to compute a
-  single 256-bins histogram. Only the YCbCr image format is supported.
-- In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
-  channels to compute a single 256-bins histogram. Only the RGB image format is
-  supported.
-
-**Byte Order.**
-All data is stored in memory in little endian format. Each cell in the tables
-contains one byte.

-Renesas R-Car VSP1 2-D Histogram Data
-
-
-Description
-===========
-
-This format describes histogram data generated by the Renesas R-Car VSP1
-2-D Histogram (HGT) engine.
-
-The VSP1 HGT is a histogram computation engine that operates on HSV
-data. It operates on a possibly cropped and subsampled input image and
-computes the sum, maximum and minimum of the S component as well as a
-weighted frequency histogram based on the H and S components.
-
-The histogram is a matrix of 6 Hue and 32 Saturation buckets, 192 in
-total. Each HSV value is added to one or more buckets with a weight
-between 1 and 16 depending on the Hue areas configuration. Finding the
-corresponding buckets is done by inspecting the H and S value independently.
-
-The Saturation position **n** (0 - 31) of the bucket in the matrix is
-found by the expression:
-
-    n = S / 8
-
-The Hue position **m** (0 - 5) of the bucket in the matrix depends on
-how the HGT Hue areas are configured. There are 6 user configurable Hue
-Areas which can be configured to cover overlapping Hue values:

-
-When two consecutive areas don't overlap (n+1L is equal to nU) the boundary
-value is considered as part of the lower area.
-
-Pixels with a hue value included in the centre of an area (between nL and nU
-included) are attributed to that single area and given a weight of 16. Pixels
-with a hue value included in the overlapping region between two areas (between
-n+1L and nU excluded) are attributed to both areas and given a weight for each
-of these areas proportional to their position along the diagonal lines
-(rounded down).
-
-The Hue area setup must match one of the following constrains:
-
-::
-
-    0L <= 0U <= 1L <= 1U <= 2L <= 2U <= 3L <= 3U <= 4L <= 4U <= 5L <= 5U

-V4L2_PIX_FMT_NV21
-Formats with ½ horizontal and vertical chroma resolution, also known as
-YUV 4:2:0. One luminance and one chrominance plane with alternating
-chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
-
-
-Description
-===========
-
-These are two-plane versions of the YUV 4:2:0 format. The three
-components are separated into two sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
-combined CbCr plane immediately follows the Y plane in memory. The CbCr
-plane is the same width, in bytes, as the Y plane (and of the image),
-but is half as tall in pixels. Each CbCr pair belongs to four pixels.
-For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
-Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`. ``V4L2_PIX_FMT_NV21`` is
-the same except the Cb and Cr bytes are swapped, the CrCb plane starts
-with a Cr byte.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.
-
-**Byte Order.**
-Each cell is one byte.

-
-
-Description
-===========
-
-This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
-three components are separated into two sub-images or planes.
-``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
-two planes are non-contiguous in memory, i.e. the chroma plane do not
-necessarily immediately follows the luma plane. The luminance data
-occupies the first plane. The Y plane has one byte per pixel. In the
-second plane there is a chrominance data with alternating chroma
-samples. The CbCr plane is the same width, in bytes, as the Y plane (and
-of the image), but is half as tall in pixels. Each CbCr pair belongs to
-four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
-Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
-``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
-``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
-arranged in 16x16 2D tiles and tiles are arranged in linear order in
-memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
-except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
-byte.
-
-``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
-applications that support the multi-planar API, described in
-:ref:`planar-apis`.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.

-
-Formats with ½ horizontal and vertical chroma resolution. This format
-has two planes - one for luminance and one for chrominance. Chroma
-samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
-memory layout. Pixels are grouped in macroblocks of 64x32 size. The
-order of macroblocks in memory is also not standard.
-
-
-Description
-===========
-
-This is the two-plane versions of the YUV 4:2:0 format where data is
-grouped into 64x32 macroblocks. The three components are separated into
-two sub-images or planes. The Y plane has one byte per pixel and pixels
-are grouped into 64x32 macroblocks. The CbCr plane has the same width,
-in bytes, as the Y plane (and the image), but is half as tall in pixels.
-The chroma plane is also grouped into 64x32 macroblocks.
-
-Width of the buffer has to be aligned to the multiple of 128, and height
-alignment is 32. Every four adjacent buffers - two horizontally and two
-vertically are grouped together and are located in memory in Z or
-flipped Z order.
-
-Layout of macroblocks in memory is presented in the following figure.

-
-    V4L2_PIX_FMT_NV12MT macroblock Z shape memory layout
-
-The requirement that width is multiple of 128 is implemented because,
-the Z shape cannot be cut in half horizontally. In case the vertical
-resolution of macroblocks is odd then the last row of macroblocks is
-arranged in a linear order.
-
-In case of chroma the layout is identical. Cb and Cr samples are
-interleaved. Height of the buffer is aligned to 32.

-V4L2_PIX_FMT_NV42
-Formats with full horizontal and vertical chroma resolutions, also known
-as YUV 4:4:4. One luminance and one chrominance plane with alternating
-chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
-
-
-Description
-===========
-
-These are two-plane versions of the YUV 4:4:4 format. The three
-components are separated into two sub-images or planes. The Y plane is
-first, with each Y sample stored in one byte per pixel. For
-``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y
-plane in memory. The CbCr plane has the same width and height, in
-pixels, as the Y plane (and the image). Each line contains one CbCr pair
-per pixel, with each Cb and Cr sample stored in one byte.
-``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are
-swapped, the CrCb plane starts with a Cr sample.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has
-twice as many pad bytes after its rows.
-
-**Byte Order.**
-Each cell is one byte.

-
-The *hue* (h) is measured in degrees, the equivalence between degrees and LSBs
-depends on the hsv-encoding used, see :ref:`colorspaces`.
-The *saturation* (s) and the *value* (v) are measured in percentage of the

-
-      - ``V4L2_PIX_FMT_S5C_UYVY_JPG``
-      - 'S5CI'
-      - Two-planar format used by Samsung S5C73MX cameras. The first plane
-	contains interleaved JPEG and UYVY image data, followed by meta
-	data in form of an array of offsets to the UYVY data blocks. The
-	actual pointer array follows immediately the interleaved JPEG/UYVY
-	data, the number of entries in this array equals the height of the
-	UYVY image. Each entry is a 4-byte unsigned integer in big endian
-	order and it's an offset to a single pixel line of the UYVY image.
-	The first plane can start either with JPEG or UYVY data chunk. The
-	size of a single UYVY block equals the UYVY image's width
-	multiplied by 2. The size of a JPEG chunk depends on the image and
-	can vary with each line.
-
-	The second plane, at an offset of 4084 bytes, contains a 4-byte
-	offset to the pointer array in the first plane. This offset is
-	followed by a 4-byte value indicating size of the pointer array.
-	All numbers in the second plane are also in big endian order.
-	Remaining data in the second plane is undefined. The information
-	in the second plane allows to easily find location of the pointer
-	array, which can be different for each frame. The size of the
-	pointer array is constant for given UYVY image height.
-
-	In order to extract UYVY and JPEG frames an application can
-	initially set a data pointer to the start of first plane and then
-	add an offset from the first entry of the pointers table. Such a
-	pointer indicates start of an UYVY image pixel line. Whole UYVY
-	line can be copied to a separate buffer. These steps should be
-	repeated for each line, i.e. the number of entries in the pointer
-	array. Anything what's in between the UYVY lines is JPEG data and
-	should be concatenated to form the JPEG stream.

-	The compression is lossless.
-	It is an opaque intermediate format and the MDP hardware must be
-	used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,

-      - Two-planar NV12-based format used by the video engine found on Allwinner
-	(codenamed sunxi) platforms, with 32x32 tiles for the luminance plane
-	and 32x64 tiles for the chrominance plane. The data in each tile is
-	stored in linear order, within the tile bounds. Each tile follows the
-	previous one linearly in memory (from left to right, top to bottom).
-
-	The associated buffer dimensions are aligned to match an integer number
-	of tiles, resulting in 32-aligned resolutions for the luminance plane
-	and 16-aligned resolutions for the chrominance plane (with 2x2
-	subsampling).

-Description
-===========
-
-These formats are designed to match the pixel formats of typical PC
-graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
-These are all packed-pixel formats, meaning all the data for a pixel lie
-next to each other in memory.

-.. note:: Bit 7 is the most significant bit.
-
-The usage and value of the alpha bits (a) in the ARGB and ABGR formats
-(collectively referred to as alpha formats) depend on the device type
-and hardware operation. :ref:`Capture <capture>` devices (including
-capture queues of mem-to-mem devices) fill the alpha component in
-memory. When the device outputs an alpha channel the alpha component
-will have a meaningful value. Otherwise, when the device doesn't output
-an alpha channel but can set the alpha bit to a user-configurable value,
-the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
-is used to specify that alpha value, and the alpha component of all
-pixels will be set to the value specified by that control. Otherwise a
-corresponding format without an alpha component (XRGB or XBGR) must be
-used instead of an alpha format.
-
-:ref:`Output <output>` devices (including output queues of mem-to-mem
-devices and :ref:`video output overlay <osd>` devices) read the alpha
-component from memory. When the device processes the alpha channel the
-alpha component must be filled with meaningful values by applications.
-Otherwise a corresponding format without an alpha component (XRGB or
-XBGR) must be used instead of an alpha format.
-
-The XRGB and XBGR formats contain undefined bits (-). Applications,
-devices and drivers must ignore those bits, for both
-:ref:`capture` and :ref:`output` devices.

-**Byte Order.**

-10-bit Bayer formats
-
-Description
-===========
-
-These four pixel formats are used by Intel IPU3 driver, they are raw
-sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
-to 32 bytes leaving 6 most significant bits padding in the last byte.
-The format is little endian.
-
-In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
-Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
-
-**Byte Order.**
-Each cell is one byte.

-10-bit Bayer formats expanded to 16 bits
-
-
-Description
-===========
-
-These four pixel formats are raw sRGB / Bayer formats with 10 bits per
-sample. Each sample is stored in a 16-bit word, with 6 unused
-high bits filled with zeros. Each n-pixel row contains n/2 green samples and
-n/2 blue or red samples, with alternating red and blue rows. Bytes are
-stored in memory in little endian order. They are conventionally described
-as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of
-these formats:
-
-**Byte Order.**
-Each cell is one byte, the 6 most significant bits in the high bytes
-are 0.

-10-bit Bayer formats compressed to 8 bits
-
-
-Description
-===========
-
-These four pixel formats are raw sRGB / Bayer formats with 10 bits per
-color compressed to 8 bits each, using the A-LAW algorithm. Each color
-component consumes 8 bits of memory. In other respects this format is
-similar to :ref:`V4L2-PIX-FMT-SRGGB8`.

-10-bit Bayer formats compressed to 8 bits
-
-
-Description
-===========
-
-These four pixel formats are raw sRGB / Bayer formats with 10 bits per
-colour compressed to 8 bits each, using DPCM compression. DPCM,
-differential pulse-code modulation, is lossy. Each colour component
-consumes 8 bits of memory. In other respects this format is similar to
-:ref:`V4L2-PIX-FMT-SRGGB10`.

-16-bit Bayer formats
-
-
-Description
-===========
-
-These four pixel formats are raw sRGB / Bayer formats with 16 bits per
-sample. Each sample is stored in a 16-bit word. Each n-pixel row contains
-n/2 green samples and n/2 blue or red samples, with alternating red and blue
-rows. Bytes are stored in memory in little endian order. They are
-conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is
-an example of a small V4L2_PIX_FMT_SBGGR16 image:

-      - Image height in pixels. If ``field`` is one of ``V4L2_FIELD_TOP``,
-	``V4L2_FIELD_BOTTOM`` or ``V4L2_FIELD_ALTERNATE`` then height
-	refers to the number of lines in the field, otherwise it refers to
-	the number of lines in the frame (which is twice the field height
-	for interlaced formats).
-    * - :cspan:`2` Applications set these fields to request an image
-	size, drivers return the closest possible values. In case of
-	planar formats the ``width`` and ``height`` applies to the largest
-	plane. To avoid ambiguities drivers must return values rounded up
-	to a multiple of the scale factor of any smaller planes. For
-	example when the image format is YUV 4:2:0, ``width`` and
-	``height`` must be multiples of two.
-
-	For compressed formats that contain the resolution information encoded
-	inside the stream, when fed to a stateful mem2mem decoder, the fields
-	may be zero to rely on the decoder to detect the right values. For more
-	details see :ref:`decoder` and format descriptions.
-    * - __u32
-      - ``pixelformat``
-      - The pixel format or type of compression, set by the application.
-	This is a little endian
-	:ref:`four character code <v4l2-fourcc>`. V4L2 defines standard
-	RGB formats in :ref:`pixfmt-rgb`, YUV formats in
-	:ref:`yuv-formats`, and reserved codes in
-	:ref:`reserved-formats`
-    * - __u32
-      - ``field``
-      - Field order, from enum :c:type:`v4l2_field`.
-        Video images are typically interlaced. Applications can request to
-	capture or output only the top or bottom field, or both fields
-	interlaced or sequentially stored in one buffer or alternating in
-	separate buffers. Drivers return the actual field order selected.
-	For more details on fields see :ref:`field-order`.
-    * - __u32
-      - ``bytesperline``
-      - Distance in bytes between the leftmost pixels in two adjacent
-	lines.
-    * - :cspan:`2`
-
-	Both applications and drivers can set this field to request
-	padding bytes at the end of each line. Drivers however may ignore
-	the value requested by the application, returning ``width`` times
-	bytes per pixel or a larger value required by the hardware. That
-	implies applications can just set this field to zero to get a
-	reasonable default.
-
-	Video hardware may access padding bytes, therefore they must
-	reside in accessible memory. Consider cases where padding bytes
-	after the last line of an image cross a system page boundary.
-	Input devices may write padding bytes, the value is undefined.
-	Output devices ignore the contents of padding bytes.
-
-	When the image format is planar the ``bytesperline`` value applies
-	to the first plane and is divided by the same factor as the
-	``width`` field for the other planes. For example the Cb and Cr
-	planes of a YUV 4:2:0 image have half as many padding bytes
-	following each line as the Y plane. To avoid ambiguities drivers
-	must return a ``bytesperline`` value rounded up to a multiple of
-	the scale factor.
-
-	For compressed formats the ``bytesperline`` value makes no sense.
-	Applications and drivers must set this to 0 in that case.
-    * - __u32
-      - ``sizeimage``
-      - Size in bytes of the buffer to hold a complete image, set by the
-	driver. Usually this is ``bytesperline`` times ``height``. When
-	the image consists of variable length compressed data this is the
-	number of bytes required by the codec to support the worst-case
-	compression scenario.
-
-	The driver will set the value for uncompressed images.
-
-	Clients are allowed to set the sizeimage field for variable length
-	compressed data flagged with ``V4L2_FMT_FLAG_COMPRESSED`` at
-	:ref:`VIDIOC_ENUM_FMT`, but the driver may ignore it and set the
-	value itself, or it may modify the provided value based on
-	alignment requirements or minimum/maximum size requirements.
-	If the client wants to leave this to the driver, then it should
-	set sizeimage to 0.
-    * - __u32
-      - ``colorspace``
-      - Image colorspace, from enum :c:type:`v4l2_colorspace`.
-        This information supplements the ``pixelformat`` and must be set
-	by the driver for capture streams and by the application for
-	output streams, see :ref:`colorspaces`.
-    * - __u32
-      - ``priv``
-      - This field indicates whether the remaining fields of the
-	struct :c:type:`v4l2_pix_format`, also called the
-	extended fields, are valid. When set to
-	``V4L2_PIX_FMT_PRIV_MAGIC``, it indicates that the extended fields
-	have been correctly initialized. When set to any other value it
-	indicates that the extended fields contain undefined values.
-
-	Applications that wish to use the pixel format extended fields
-	must first ensure that the feature is supported by querying the
-	device for the :ref:`V4L2_CAP_EXT_PIX_FORMAT <querycap>`
-	capability. If the capability isn't set the pixel format extended
-	fields are not supported and using the extended fields will lead
-	to undefined results.
-
-	To use the extended fields, applications must set the ``priv``
-	field to ``V4L2_PIX_FMT_PRIV_MAGIC``, initialize all the extended
-	fields and zero the unused bytes of the
-	struct :c:type:`v4l2_format` ``raw_data`` field.
-
-	When the ``priv`` field isn't set to ``V4L2_PIX_FMT_PRIV_MAGIC``
-	drivers must act as if all the extended fields were set to zero.
-	On return drivers must set the ``priv`` field to
-	``V4L2_PIX_FMT_PRIV_MAGIC`` and all the extended fields to

-Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1
-
-
-Description
-===========
-
-In this format each 12 bytes is eight pixels. In the twelve bytes are
-two CbCr pairs and eight Y's. The first CbCr pair goes with the first
-four Y's, and the second CbCr pair goes with the other four Y's. The Cb
-and Cr components have one fourth the horizontal resolution of the Y
-component.
-
-Do not confuse this format with
-:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
-from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1

-V4L2_PIX_FMT_YUV410
-Planar formats with ¼ horizontal and vertical chroma resolution, also
-known as YUV 4:1:0
-
-
-Description
-===========
-
-These are planar formats, as opposed to a packed format. The three
-components are separated into three sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
-the Cr plane immediately follows the Y plane in memory. The Cr plane is
-¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
-belongs to 16 pixels, a four-by-four square of the image. Following the
-Cr plane is the Cb plane, just like the Cr plane.
-``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
-then the Cr plane.
-
-If the Y plane has pad bytes after each row, then the Cr and Cb planes
-have ¼ as many pad bytes after their rows. In other words, four Cx rows
-(including padding) are exactly as long as one Y row (including
-padding).
-
-**Byte Order.**
-Each cell is one byte.

-Description
-===========
-
-This format is not commonly used. This is a planar format similar to the
-4:2:2 planar format except with half as many chroma. The three
-components are separated into three sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. The Cb plane immediately
-follows the Y plane in memory. The Cb plane is ¼ the width of the Y
-plane (and of the image). Each Cb belongs to 4 pixels all on the same
-row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
-Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane,
-just like the Cb plane.
-
-If the Y plane has pad bytes after each row, then the Cr and Cb planes
-have ¼ as many pad bytes after their rows. In other words, four C x rows
-(including padding) is exactly as long as one Y row (including padding).

-
-
-Description
-===========
-
-This is a multi-planar format, as opposed to a packed format. The three
-components are separated into three sub-images or planes.
-
-The Y plane is first. The Y plane has one byte per pixel. For
-``V4L2_PIX_FMT_YUV420M`` the Cb data constitutes the second plane which
-is half the width and half the height of the Y plane (and of the image).
-Each Cb belongs to four pixels, a two-by-two square of the image. For
-example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
-Y'\ :sub:`10`, and Y'\ :sub:`11`. The Cr data, just like the Cb plane,
-is in the third plane.
-
-``V4L2_PIX_FMT_YVU420M`` is the same except the Cr data is stored in the
-second plane and the Cb data in the third plane.
-
-If the Y plane has pad bytes after each row, then the Cb and Cr planes
-have half as many pad bytes after their rows. In other words, two Cx
-rows (including padding) is exactly as long as one Y row (including
-padding).
-
-``V4L2_PIX_FMT_YUV420M`` and ``V4L2_PIX_FMT_YVU420M`` are intended to be
-used only in drivers and applications that support the multi-planar API,
-described in :ref:`planar-apis`.

-V4L2_PIX_FMT_YVU422M
-Planar formats with ½ horizontal resolution, also known as YUV and YVU
-4:2:2
-
-
-Description
-===========
-
-This is a multi-planar format, as opposed to a packed format. The three
-components are separated into three sub-images or planes.
-
-The Y plane is first. The Y plane has one byte per pixel. For
-``V4L2_PIX_FMT_YUV422M`` the Cb data constitutes the second plane which
-is half the width of the Y plane (and of the image). Each Cb belongs to
-two pixels. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`,
-Y'\ :sub:`01`. The Cr data, just like the Cb plane, is in the third
-plane.
-
-``V4L2_PIX_FMT_YVU422M`` is the same except the Cr data is stored in the
-second plane and the Cb data in the third plane.
-
-If the Y plane has pad bytes after each row, then the Cb and Cr planes
-have half as many pad bytes after their rows. In other words, two Cx
-rows (including padding) is exactly as long as one Y row (including
-padding).
-
-``V4L2_PIX_FMT_YUV422M`` and ``V4L2_PIX_FMT_YVU422M`` are intended to be
-used only in drivers and applications that support the multi-planar API,
-described in :ref:`planar-apis`.
-
-**Byte Order.**
-Each cell is one byte.

-The V4L2 API was primarily designed for devices exchanging image data

-*****************************
-Single- and multi-planar APIs
-*****************************
-
-Some devices require data for each input or output video frame to be
-placed in discontiguous memory buffers. In such cases, one video frame
-has to be addressed using more than one memory address, i.e. one pointer
-per "plane". A plane is a sub-buffer of the current frame. For examples
-of such formats see :ref:`pixfmt`.
-
-Initially, V4L2 API did not support multi-planar buffers and a set of
-extensions has been introduced to handle them. Those extensions
-constitute what is being referred to as the "multi-planar API".
-
-Some of the V4L2 API calls and structures are interpreted differently,
-depending on whether single- or multi-planar API is being used. An
-application can choose whether to use one or the other by passing a
-corresponding buffer type to its ioctl calls. Multi-planar versions of
-buffer types are suffixed with an ``_MPLANE`` string. For a list of
-available multi-planar buffer types see enum
-:c:type:`v4l2_buf_type`.
-
-
-Multi-planar formats
-====================
-
-Multi-planar API introduces new multi-planar formats. Those formats use
-a separate set of FourCC codes. It is important to distinguish between
-the multi-planar API and a multi-planar format. Multi-planar API calls
-can handle all single-planar formats as well (as long as they are passed
-in multi-planar API structures), while the single-planar API cannot
-handle multi-planar formats.
-
-
-Calls that distinguish between single and multi-planar APIs
-===========================================================
-
-:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>`
-    Two additional multi-planar capabilities are added. They can be set
-    together with non-multi-planar ones for devices that handle both
-    single- and multi-planar formats.
-
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`
-    New structures for describing multi-planar formats are added: struct
-    :c:type:`v4l2_pix_format_mplane` and
-    struct :c:type:`v4l2_plane_pix_format`.
-    Drivers may define new multi-planar formats, which have distinct
-    FourCC codes from the existing single-planar ones.
-
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>`
-    A new struct :c:type:`v4l2_plane` structure for
-    describing planes is added. Arrays of this structure are passed in
-    the new ``m.planes`` field of struct
-    :c:type:`v4l2_buffer`.
-
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
-    Will allocate multi-planar buffers as requested.

-*********************
-Querying Capabilities
-*********************
-
-Because V4L2 covers a wide variety of devices not all aspects of the API
-are equally applicable to all types of devices. Furthermore devices of
-the same type have different capabilities and this specification permits
-the omission of a few complicated and less important parts of the API.
-
-The :ref:`VIDIOC_QUERYCAP` ioctl is available to
-check if the kernel device is compatible with this specification, and to
-query the :ref:`functions <devices>` and :ref:`I/O methods <io>`
-supported by the device.
-
-Starting with kernel version 3.1, :ref:`VIDIOC_QUERYCAP`
-will return the V4L2 API version used by the driver, with generally
-matches the Kernel version. There's no need of using
-:ref:`VIDIOC_QUERYCAP` to check if a specific ioctl
-is supported, the V4L2 core now returns ``ENOTTY`` if a driver doesn't
-provide support for an ioctl.
-
-Other features can be queried by calling the respective ioctl, for
-example :ref:`VIDIOC_ENUMINPUT` to learn about the
-number, types and names of video connectors on the device. Although
-abstraction is a major objective of this API, the
-:ref:`VIDIOC_QUERYCAP` ioctl also allows driver
-specific applications to reliably identify the driver.
-
-All V4L2 drivers must support :ref:`VIDIOC_QUERYCAP`.
-Applications should always call this ioctl after opening the device.

-Read/Write
-**********
-
-Input and output devices support the :ref:`read() <func-read>` and
-:ref:`write() <func-write>` function, respectively, when the
-``V4L2_CAP_READWRITE`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set.
-
-Drivers may need the CPU to copy the data, but they may also support DMA
-to or from user memory, so this I/O method is not necessarily less
-efficient than other methods merely exchanging buffer pointers. It is
-considered inferior though because no meta-information like frame
-counters or timestamps are passed. This information is necessary to
-recognize frame dropping and to synchronize with other data streams.
-However this is also the simplest I/O method, requiring little or no
-setup to exchange data. It permits command line stunts like this (the
-vidctrl tool is fictitious):
-
-
-.. code-block:: none
-
-    $ vidctrl /dev/video --input=0 --format=YUYV --size=352x288
-    $ dd if=/dev/video of=myimage.422 bs=202752 count=1
-
-To read from the device applications use the :ref:`read() <func-read>`
-function, to write the :ref:`write() <func-write>` function. Drivers
-must implement one I/O method if they exchange data with applications,
-but it need not be this. [#f1]_ When reading or writing is supported, the
-driver must also support the :ref:`select() <func-select>` and
-:ref:`poll() <func-poll>` function. [#f2]_
-
-.. [#f1]
-   It would be desirable if applications could depend on drivers
-   supporting all I/O interfaces, but as much as the complex memory
-   mapping I/O can be inadequate for some devices we have no reason to
-   require this interface, which is most useful for simple applications
-   capturing still images.
-
-.. [#f2]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.

-*************
-Configuration
-*************
-
-Applications can use the :ref:`selection API <VIDIOC_G_SELECTION>` to
-select an area in a video signal or a buffer, and to query for default
-settings and hardware limits.
-
-Video hardware can have various cropping, composing and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in the horizontal and
-vertical directions. Also it may not support scaling at all. At the same
-time the cropping/composing rectangles may have to be aligned, and both
-the source and the sink may have arbitrary upper and lower size limits.
-Therefore, as usual, drivers are expected to adjust the requested
-parameters and return the actual values selected. An application can
-control the rounding behaviour using
-:ref:`constraint flags <v4l2-selection-flags>`.
-
-
-Configuration of video capture
-==============================
-
-See figure :ref:`sel-targets-capture` for examples of the selection
-targets available for a video capture device. It is recommended to
-configure the cropping targets before to the composing targets.
-
-The range of coordinates of the top left corner, width and height of
-areas that can be sampled is given by the ``V4L2_SEL_TGT_CROP_BOUNDS``
-target. It is recommended for the driver developers to put the top/left
-corner at position ``(0,0)``. The rectangle's coordinates are expressed
-in pixels.
-
-The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by the ``V4L2_SEL_TGT_CROP`` target.
-It uses the same coordinate system as ``V4L2_SEL_TGT_CROP_BOUNDS``. The
-active cropping area must lie completely inside the capture boundaries.
-The driver may further adjust the requested size and/or position
-according to hardware limitations.
-
-Each capture device has a default source rectangle, given by the
-``V4L2_SEL_TGT_CROP_DEFAULT`` target. This rectangle shall cover what the
-driver writer considers the complete picture. Drivers shall set the
-active crop rectangle to the default when the driver is first loaded,
-but not later.
-
-The composing targets refer to a memory buffer. The limits of composing
-coordinates are obtained using ``V4L2_SEL_TGT_COMPOSE_BOUNDS``. All
-coordinates are expressed in pixels. The rectangle's top/left corner
-must be located at position ``(0,0)``. The width and height are equal to
-the image size set by :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
-
-The part of a buffer into which the image is inserted by the hardware is
-controlled by the ``V4L2_SEL_TGT_COMPOSE`` target. The rectangle's
-coordinates are also expressed in the same coordinate system as the
-bounds rectangle. The composing rectangle must lie completely inside
-bounds rectangle. The driver must adjust the composing rectangle to fit
-to the bounding limits. Moreover, the driver can perform other
-adjustments according to hardware limitations. The application can
-control rounding behaviour using
-:ref:`constraint flags <v4l2-selection-flags>`.
-
-For capture devices the default composing rectangle is queried using
-``V4L2_SEL_TGT_COMPOSE_DEFAULT``. It is usually equal to the bounding
-rectangle.
-
-The part of a buffer that is modified by the hardware is given by
-``V4L2_SEL_TGT_COMPOSE_PADDED``. It contains all pixels defined using
-``V4L2_SEL_TGT_COMPOSE`` plus all padding data modified by hardware
-during insertion process. All pixels outside this rectangle *must not*
-be changed by the hardware. The content of pixels that lie inside the
-padded area but outside active area is undefined. The application can
-use the padded and active rectangles to detect where the rubbish pixels
-are located and remove them if needed.
-
-
-Configuration of video output
-=============================
-
-For output devices targets and ioctls are used similarly to the video
-capture case. The *composing* rectangle refers to the insertion of an
-image into a video signal. The cropping rectangles refer to a memory
-buffer. It is recommended to configure the composing targets before to
-the cropping targets.
-
-The cropping targets refer to the memory buffer that contains an image
-to be inserted into a video signal or graphical screen. The limits of
-cropping coordinates are obtained using ``V4L2_SEL_TGT_CROP_BOUNDS``.
-All coordinates are expressed in pixels. The top/left corner is always
-point ``(0,0)``. The width and height is equal to the image size
-specified using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-The top left corner, width and height of the source rectangle, that is
-the area from which image date are processed by the hardware, is given
-by the ``V4L2_SEL_TGT_CROP``. Its coordinates are expressed in in the
-same coordinate system as the bounds rectangle. The active cropping area
-must lie completely inside the crop boundaries and the driver may
-further adjust the requested size and/or position according to hardware
-limitations.
-
-For output devices the default cropping rectangle is queried using
-``V4L2_SEL_TGT_CROP_DEFAULT``. It is usually equal to the bounding
-rectangle.
-
-The part of a video signal or graphics display where the image is
-inserted by the hardware is controlled by ``V4L2_SEL_TGT_COMPOSE``
-target. The rectangle's coordinates are expressed in pixels. The
-composing rectangle must lie completely inside the bounds rectangle. The
-driver must adjust the area to fit to the bounding limits. Moreover, the
-driver can perform other adjustments according to hardware limitations.
-
-The device has a default composing rectangle, given by the
-``V4L2_SEL_TGT_COMPOSE_DEFAULT`` target. This rectangle shall cover what
-the driver writer considers the complete picture. It is recommended for
-the driver developers to put the top/left corner at position ``(0,0)``.
-Drivers shall set the active composing rectangle to the default one when
-the driver is first loaded.
-
-The devices may introduce additional content to video signal other than
-an image from memory buffers. It includes borders around an image.
-However, such a padded area is driver-dependent feature not covered by
-this document. Driver developers are encouraged to keep padded rectangle
-equal to active one. The padded target is accessed by the
-``V4L2_SEL_TGT_COMPOSE_PADDED`` identifier. It must contain all pixels
-from the ``V4L2_SEL_TGT_COMPOSE`` target.
-
-
-Scaling control
-===============
-
-An application can detect if scaling is performed by comparing the width
-and the height of rectangles obtained using ``V4L2_SEL_TGT_CROP`` and
-``V4L2_SEL_TGT_COMPOSE`` targets. If these are not equal then the
-scaling is applied. The application can compute the scaling ratios using
-these values.

-Introduction
-************
-
-Some video capture devices can sample a subsection of a picture and
-shrink or enlarge it to an image of arbitrary size. Next, the devices
-can insert the image into larger one. Some video output devices can crop
-part of an input image, scale it up or down and insert it at an
-arbitrary scan line and horizontal offset into a video signal. We call
-these abilities cropping, scaling and composing.
-
-On a video *capture* device the source is a video signal, and the
-cropping target determine the area actually sampled. The sink is an
-image stored in a memory buffer. The composing area specifies which part
-of the buffer is actually written to by the hardware.
-
-On a video *output* device the source is an image in a memory buffer,
-and the cropping target is a part of an image to be shown on a display.
-The sink is the display or the graphics screen. The application may
-select the part of display where the image should be displayed. The size
-and position of such a window is controlled by the compose target.
-
-Rectangles for all cropping and composing targets are defined even if
-the device does supports neither cropping nor composing. Their size and
-position will be fixed in such a case. If the device does not support
-scaling then the cropping and composing rectangles have the same size.

-********************************
-Comparison with old cropping API
-********************************
-
-The selection API was introduced to cope with deficiencies of the
-older :ref:`CROP API <crop>`, that was designed to control simple
-capture devices. Later the cropping API was adopted by video output
-drivers. The ioctls are used to select a part of the display were the
-video signal is inserted. It should be considered as an API abuse
-because the described operation is actually the composing. The
-selection API makes a clear distinction between composing and cropping
-operations by setting the appropriate targets.
-
-The CROP API lacks any support for composing to and cropping from an
-image inside a memory buffer. The application could configure a
-capture device to fill only a part of an image by abusing V4L2
-API. Cropping a smaller image from a larger one is achieved by setting
-the field ``bytesperline`` at struct :c:type:`v4l2_pix_format`.
-Introducing an image offsets could be done by modifying field
-``m_userptr`` at struct :c:type:`v4l2_buffer` before calling
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`. Those operations should be avoided
-because they are not portable (endianness), and do not work for
-macroblock and Bayer formats and mmap buffers.
-
-The selection API deals with configuration of buffer
-cropping/composing in a clear, intuitive and portable way. Next, with
-the selection API the concepts of the padded target and constraints
-flags are introduced. Finally, struct :c:type:`v4l2_crop` and struct
-:c:type:`v4l2_cropcap` have no reserved fields. Therefore there is no
-way to extend their functionality. The new struct
-:c:type:`v4l2_selection` provides a lot of place for future
-extensions.
-
-Driver developers are encouraged to implement only selection API. The
-former cropping API would be simulated using the new one.

-Video Standards
-***************
-
-Video devices typically support one or more different video standards or
-variations of standards. Each video input and output may support another
-set of standards. This set is reported by the ``std`` field of struct
-:c:type:`v4l2_input` and struct
-:c:type:`v4l2_output` returned by the
-:ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` ioctls, respectively.
-
-V4L2 defines one bit for each analog video standard currently in use
-worldwide, and sets aside bits for driver defined standards, e. g.
-hybrid standards to watch NTSC video tapes on PAL TVs and vice versa.
-Applications can use the predefined bits to select a particular
-standard, although presenting the user a menu of supported standards is
-preferred. To enumerate and query the attributes of the supported
-standards applications use the :ref:`VIDIOC_ENUMSTD`
-ioctl.
-
-Many of the defined standards are actually just variations of a few
-major standards. The hardware may in fact not distinguish between them,
-or do so internal and switch automatically. Therefore enumerated
-standards also contain sets of one or more standard bits.
-
-Assume a hypothetic tuner capable of demodulating B/PAL, G/PAL and I/PAL
-signals. The first enumerated standard is a set of B and G/PAL, switched
-automatically depending on the selected radio frequency in UHF or VHF
-band. Enumeration gives a "PAL-B/G" or "PAL-I" choice. Similar a
-Composite input may collapse standards, enumerating "PAL-B/G/H/I",
-"NTSC-M" and "SECAM-D/K". [#f1]_
-
-To query and select the standard used by the current video input or
-output applications call the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
-:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctl, respectively. The
-*received* standard can be sensed with the
-:ref:`VIDIOC_QUERYSTD` ioctl.
-
-.. note::
-
-   The parameter of all these ioctls is a pointer to a
-   :ref:`v4l2_std_id <v4l2-std-id>` type (a standard set), *not* an
-   index into the standard enumeration. Drivers must implement all video
-   standard ioctls when the device has one or more video inputs or outputs.
-
-Special rules apply to devices such as USB cameras where the notion of
-video standards makes little sense. More generally for any capture or
-output device which is:
-
--  incapable of capturing fields or frames at the nominal rate of the
-   video standard, or
-
--  that does not support the video standard formats at all.
-
-Here the driver shall set the ``std`` field of struct
-:c:type:`v4l2_input` and struct
-:c:type:`v4l2_output` to zero and the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`,
-:ref:`VIDIOC_S_STD <VIDIOC_G_STD>`, :ref:`VIDIOC_QUERYSTD` and :ref:`VIDIOC_ENUMSTD` ioctls
-shall return the ``ENOTTY`` error code or the ``EINVAL`` error code.
-
-Applications can make use of the :ref:`input-capabilities` and
-:ref:`output-capabilities` flags to determine whether the video
-standard ioctls can be used with the given input or output.

-Streaming Parameters
-********************
-
-Streaming parameters are intended to optimize the video capture process
-as well as I/O. Presently applications can request a high quality
-capture mode with the :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl.
-
-The current video standard determines a nominal number of frames per
-second. If less than this number of frames is to be captured or output,
-applications can request frame skipping or duplicating on the driver
-side. This is especially useful when using the
-:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are
-not augmented by timestamps or sequence counters, and to avoid
-unnecessary data copying.
-
-Finally these ioctls can be used to determine the number of buffers used
-internally by a driver in read/write mode. For implications see the
-section discussing the :ref:`read() <func-read>` function.
-
-To get and set the streaming parameters applications call the
-:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
-:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take
-a pointer to a struct :c:type:`v4l2_streamparm`, which
-contains a union holding separate parameters for input and output
-devices.
-
-These ioctls are optional, drivers need not implement them. If so, they
-return the ``EINVAL`` error code.

-Media Bus Pixel Codes
----------------------
-
-The media bus pixel codes describe image formats as flowing over
-physical buses (both between separate physical components and inside
-SoC devices). This should not be confused with the V4L2 pixel formats
-that describe, using four character codes, image formats as stored in
-memory.
-
-While there is a relationship between image formats on buses and image
-formats in memory (a raw Bayer image won't be magically converted to
-JPEG just by storing it to memory), there is no one-to-one
-correspondence between them.
-
-The media bus pixel codes document parallel formats. Should the pixel data be
-transported over a serial bus, the media bus pixel code that describes a
-parallel format that transfers a sample on a single clock cycle is used. For
-instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used
-on parallel busses for transferring an 8 bits per sample BGR data, whereas on
-serial busses the data in this format is only referred to using
-MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single
-way to transport that format on the serial busses.
-
-Packed RGB Formats
-^^^^^^^^^^^^^^^^^^
-
-Those formats transfer pixel data as red, green and blue components. The
-format code is made of the following information.
-
--  The red, green and blue components order code, as encoded in a pixel
-   sample. Possible values are RGB and BGR.
-
--  The number of bits per component, for each component. The values can
-   be different for all components. Common values are 555 and 565.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   1 and 2.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO). A "C" prefix is used for
-   component-wise padding in the most high order bits (CPADHI) or low
-   order bits (CPADLO) of each separate component.
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).
-
-For instance, a format where pixels are encoded as 5-bits red, 5-bits
-green and 5-bit blue values padded on the high bit, transferred as 2
-8-bit samples per pixel with the most significant bits (padding, red and
-half of the green value) transferred first will be named
-``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``.
-
-The following tables list existing packed RGB formats.
-
-.. HACK: ideally, we would be using adjustbox here. However, Sphinx
-.. is a very bad behaviored guy: if the table has more than 30 cols,
-.. it switches to long table, and there's no way to override it.

-On LVDS buses, usually each sample is transferred serialized in seven
-time slots per pixel clock, on three (18-bit) or four (24-bit)
-differential data pairs at the same time. The remaining bits are used
-for control signals as defined by SPWG/PSWG/VESA or JEIDA standards. The
-24-bit RGB format serialized in seven time slots on four lanes using
-JEIDA defined bit mapping will be named
-``MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA``, for example.

-Bayer Formats
-^^^^^^^^^^^^^
-
-Those formats transfer pixel data as red, green and blue components. The
-format code is made of the following information.
-
--  The red, green and blue components order code, as encoded in a pixel
-   sample. The possible values are shown in :ref:`bayer-patterns`.
-
--  The number of bits per pixel component. All components are
-   transferred on the same number of bits. Common values are 8, 10 and
-   12.
-
--  The compression (optional). If the pixel components are ALAW- or
-   DPCM-compressed, a mention of the compression scheme and the number
-   of bits per compressed pixel component.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   1 and 2.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO).
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).
-
-For instance, a format with uncompressed 10-bit Bayer components
-arranged in a red, green, green, blue pattern transferred as 2 8-bit
-samples per pixel with the least significant bits transferred first will
-be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``.

-Packed YUV Formats
-^^^^^^^^^^^^^^^^^^
-
-Those data formats transfer pixel data as (possibly downsampled) Y, U
-and V components. Some formats include dummy bits in some of their
-samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma)
-formats. One cannot rely on the values of these dummy bits as those are
-undefined.
-
-The format code is made of the following information.
-
--  The Y, U and V components order code, as transferred on the bus.
-   Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
-   dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC
-   formats.
-
--  The number of bits per pixel component. All components are
-   transferred on the same number of bits. Common values are 8, 10 and
-   12.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   0.5 (encoded as 0_5; in this case two pixels are transferred per bus
-   sample), 1, 1.5 (encoded as 1_5) and 2.
-
--  The bus width. When the bus width is larger than the number of bits
-   per pixel component, several components are packed in a single bus
-   sample. The components are ordered as specified by the order code,
-   with components on the left of the code transferred in the high order
-   bits. Common values are 8 and 16.
-
-For instance, a format where pixels are encoded as 8-bit YUV values
-downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in
-the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``.
-
-:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and
-describes the organization of each pixel data in each sample. When a
-format pattern is split across multiple samples each of the samples in
-the pattern is described.
-
-The role of each bit transferred over the bus is identified by one of
-the following codes.
-
--  y\ :sub:`x` for luma component bit number x
-
--  u\ :sub:`x` for blue chroma component bit number x
-
--  v\ :sub:`x` for red chroma component bit number x
-
--  a\ :sub:`x` for alpha component bit number x
-
-- for non-available bits (for positions higher than the bus width)
-
--  d for dummy bits

-HSV/HSL Formats
-^^^^^^^^^^^^^^^
-
-Those formats transfer pixel data as RGB values in a
-cylindrical-coordinate system using Hue-Saturation-Value or
-Hue-Saturation-Lightness components. The format code is made of the
-following information.
-
--  The hue, saturation, value or lightness and optional alpha components
-   order code, as encoded in a pixel sample. The only currently
-   supported value is AHSV.
-
--  The number of bits per component, for each component. The values can
-   be different for all components. The only currently supported value
-   is 8888.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. The only currently
-   supported value is 1.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO).
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).

-JPEG Compressed Formats
-^^^^^^^^^^^^^^^^^^^^^^^
-
-Those data formats consist of an ordered sequence of 8-bit bytes
-obtained from JPEG compression process. Additionally to the ``_JPEG``
-postfix the format code is made of the following information.
-
--  The number of bus samples per entropy encoded byte.
-
--  The bus width.
-
-For instance, for a JPEG baseline process and an 8-bit bus width the
-format will be named ``MEDIA_BUS_FMT_JPEG_1X8``.
-
-The following table lists existing JPEG compressed formats.

-*********************
-Tuners and Modulators
-*********************
-
-
-Tuners
-======
-
-Video input devices can have one or more tuners demodulating a RF
-signal. Each tuner is associated with one or more video inputs,
-depending on the number of RF connectors on the tuner. The ``type``
-field of the respective struct :c:type:`v4l2_input`
-returned by the :ref:`VIDIOC_ENUMINPUT` ioctl is
-set to ``V4L2_INPUT_TYPE_TUNER`` and its ``tuner`` field contains the
-index number of the tuner.
-
-Radio input devices have exactly one tuner with index zero, no video
-inputs.
-
-To query and change tuner properties applications use the
-:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
-:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` ioctls, respectively. The
-struct :c:type:`v4l2_tuner` returned by :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>`
-also contains signal status information applicable when the tuner of the
-current video or radio input is queried.
-
-.. note::
-
-   :ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` does not switch the
-   current tuner, when there is more than one. The tuner is solely
-   determined by the current video input. Drivers must support both ioctls
-   and set the ``V4L2_CAP_TUNER`` flag in the struct :c:type:`v4l2_capability`
-   returned by the :ref:`VIDIOC_QUERYCAP` ioctl when the
-   device has one or more tuners.
-
-
-Modulators
-==========
-
-Video output devices can have one or more modulators, that modulate a
-video signal for radiation or connection to the antenna input of a TV
-set or video recorder. Each modulator is associated with one or more
-video outputs, depending on the number of RF connectors on the
-modulator. The ``type`` field of the respective struct
-:c:type:`v4l2_output` returned by the
-:ref:`VIDIOC_ENUMOUTPUT` ioctl is set to
-``V4L2_OUTPUT_TYPE_MODULATOR`` and its ``modulator`` field contains the
-index number of the modulator.
-
-Radio output devices have exactly one modulator with index zero, no
-video outputs.
-
-A video or radio device cannot support both a tuner and a modulator. Two
-separate device nodes will have to be used for such hardware, one that
-supports the tuner functionality and one that supports the modulator
-functionality. The reason is a limitation with the
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl where you
-cannot specify whether the frequency is for a tuner or a modulator.
-
-To query and change modulator properties applications use the
-:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` and
-:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Note that
-:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` does not switch the current modulator, when there
-is more than one at all. The modulator is solely determined by the
-current video output. Drivers must support both ioctls and set the
-``V4L2_CAP_MODULATOR`` flag in the struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl when the device has
-one or more modulators.
-
-
-Radio Frequency
-===============
-
-To get and set the tuner or modulator radio frequency applications use
-the :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl which both take
-a pointer to a struct :c:type:`v4l2_frequency`. These
-ioctls are used for TV and radio devices alike. Drivers must support
-both ioctls when the tuner or modulator ioctls are supported, or when
-the device is a radio device.

-*****************************
-Streaming I/O (User Pointers)
-*****************************
-
-Input and output devices support this I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set. If the
-particular user pointer method (not only memory mapping) is supported
-must be determined by calling the :ref:`VIDIOC_REQBUFS` ioctl
-with the memory type set to ``V4L2_MEMORY_USERPTR``.
-
-This I/O method combines advantages of the read/write and memory mapping
-methods. Buffers (planes) are allocated by the application itself, and
-can reside for example in virtual or shared memory. Only pointers to
-data are exchanged, these pointers and meta-information are passed in
-struct :c:type:`v4l2_buffer` (or in struct
-:c:type:`v4l2_plane` in the multi-planar API case). The
-driver must be switched into user pointer I/O mode by calling the
-:ref:`VIDIOC_REQBUFS` with the desired buffer type.
-No buffers (planes) are allocated beforehand, consequently they are not
-indexed and cannot be queried like mapped buffers with the
-:ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>` ioctl.
-
-Example: Initiating streaming I/O with user pointers
-====================================================
-
-.. code-block:: c
-
-    struct v4l2_requestbuffers reqbuf;
-
-    memset (&reqbuf, 0, sizeof (reqbuf));
-    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-    reqbuf.memory = V4L2_MEMORY_USERPTR;
-
-    if (ioctl (fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
-	if (errno == EINVAL)
-	    printf ("Video capturing or user pointer streaming is not supported\\n");
-	else
-	    perror ("VIDIOC_REQBUFS");
-
-	exit (EXIT_FAILURE);
-    }
-
-Buffer (plane) addresses and sizes are passed on the fly with the
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. Although buffers are commonly
-cycled, applications can pass different addresses and sizes at each
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call. If required by the hardware the
-driver swaps memory pages within physical memory to create a continuous
-area of memory. This happens transparently to the application in the
-virtual memory subsystem of the kernel. When buffer pages have been
-swapped out to disk they are brought back and finally locked in physical
-memory for DMA. [#f1]_
-
-Filled or displayed buffers are dequeued with the
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
-memory pages at any time between the completion of the DMA and this
-ioctl. The memory is also unlocked when
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
-:ref:`VIDIOC_REQBUFS`, or when the device is closed.
-Applications must take care not to free buffers without dequeuing.
-Firstly, the buffers remain locked for longer, wasting physical memory.
-Secondly the driver will not be notified when the memory is returned to
-the application's free list and subsequently reused for other purposes,
-possibly completing the requested DMA and overwriting valuable data.
-
-For capturing applications it is customary to enqueue a number of empty
-buffers, to start capturing and enter the read loop. Here the
-application waits until a filled buffer can be dequeued, and re-enqueues
-the buffer when the data is no longer needed. Output applications fill
-and enqueue buffers, when enough buffers are stacked up output is
-started. In the write loop, when the application runs out of free
-buffers it must wait until an empty buffer can be dequeued and reused.
-Two methods exist to suspend execution of the application until one or
-more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
-``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The :ref:`select()
-<func-select>` or :ref:`poll() <func-poll>` function are always
-available.
-
-To start and stop capturing or output applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctl.
-
-.. note::
-
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
-   both queues and unlocks all buffers as a side effect. Since there is no
-   notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
-   outputted buffers.
-
-Drivers implementing user pointer I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>` function. [#f2]_
-
-.. [#f1]
-   We expect that frequently used buffers are typically not swapped out.
-   Anyway, the process of swapping, locking or generating scatter-gather
-   lists may be time consuming. The delay can be masked by the depth of
-   the incoming buffer queue, and perhaps by maintaining caches assuming
-   a buffer will be soon enqueued again. On the other hand, to optimize
-   memory usage drivers can limit the number of buffers locked in
-   advance and recycle the most recently used buffers first. Of course,
-   the pages of empty buffers in the incoming queue need not be saved to
-   disk. Output buffers must be saved on the incoming and outgoing queue
-   because an application may share them with other processes.
-
-.. [#f2]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.
-   The rest should be evident.

-Video Inputs and Outputs
-************************
-
-Video inputs and outputs are physical connectors of a device. These can
-be for example: RF connectors (antenna/cable), CVBS a.k.a. Composite
-Video, S-Video and RGB connectors. Camera sensors are also considered to
-be a video input. Video and VBI capture devices have inputs. Video and
-VBI output devices have outputs, at least one each. Radio devices have
-no video inputs or outputs.
-
-To learn about the number and attributes of the available inputs and
-outputs applications can enumerate them with the
-:ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` ioctl, respectively. The
-struct :c:type:`v4l2_input` returned by the
-:ref:`VIDIOC_ENUMINPUT` ioctl also contains signal
-status information applicable when the current video input is queried.
-
-The :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` ioctls return the index of
-the current video input or output. To select a different input or output
-applications call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` ioctls. Drivers must
-implement all the input ioctls when the device has one or more inputs,
-all the output ioctls when the device has one or more outputs.
-
-Example: Information about the current video input
-==================================================
-
-.. code-block:: c
-
-    struct v4l2_input input;
-    int index;
-
-    if (-1 == ioctl(fd, VIDIOC_G_INPUT, &index)) {
-	perror("VIDIOC_G_INPUT");
-	exit(EXIT_FAILURE);
-    }
-
-    memset(&input, 0, sizeof(input));
-    input.index = index;
-
-    if (-1 == ioctl(fd, VIDIOC_ENUMINPUT, &input)) {
-	perror("VIDIOC_ENUMINPUT");
-	exit(EXIT_FAILURE);
-    }
-
-    printf("Current input: %s\\n", input.name);

-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_CREATE_BUFS, struct v4l2_create_buffers *argp )
-    :name: VIDIOC_CREATE_BUFS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_create_buffers`.
-
-
-Description
-===========
-
-This ioctl is used to create buffers for :ref:`memory mapped <mmap>`
-or :ref:`user pointer <userp>` or :ref:`DMA buffer <dmabuf>` I/O. It
-can be used as an alternative or in addition to the
-:ref:`VIDIOC_REQBUFS` ioctl, when a tighter control
-over buffers is required. This ioctl can be called multiple times to
-create buffers of different sizes.
-
-To allocate the device buffers applications must initialize the relevant
-fields of the struct :c:type:`v4l2_create_buffers` structure. The
-``count`` field must be set to the number of requested buffers, the
-``memory`` field specifies the requested I/O method and the ``reserved``
-array must be zeroed.
-
-The ``format`` field specifies the image format that the buffers must be
-able to handle. The application has to fill in this struct
-:c:type:`v4l2_format`. Usually this will be done using the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` or
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctls to ensure that the
-requested format is supported by the driver. Based on the format's
-``type`` field the requested buffer size (for single-planar) or plane
-sizes (for multi-planar formats) will be used for the allocated buffers.
-The driver may return an error if the size(s) are not supported by the
-hardware (usually because they are too small).
-
-The buffers created by this ioctl will have as minimum size the size
-defined by the ``format.pix.sizeimage`` field (or the corresponding
-fields for other format types). Usually if the ``format.pix.sizeimage``
-field is less than the minimum required for the given format, then an
-error will be returned since drivers will typically not allow this. If
-it is larger, then the value will be used as-is. In other words, the
-driver may reject the requested size, but if it is accepted the driver
-will use it unchanged.
-
-When the ioctl is called with a pointer to this structure the driver
-will attempt to allocate up to the requested number of buffers and store
-the actual number allocated and the starting index in the ``count`` and
-the ``index`` fields respectively. On return ``count`` can be smaller
-than the number requested.

-	guaranteed to support ``V4L2_MEMORY_MMAP`` and *might* support
-	other :c:type:`v4l2_memory` types. It will not support any others
-	capabilities. See :ref:`here <v4l2-buf-capabilities>` for a list of the
-	capabilities.
-
-	If you want to just query the capabilities without making any

-
-
-Description
-===========
-
-Applications use this function to query the cropping limits, the pixel
-aspect of images and to calculate scale factors. They set the ``type``
-field of a v4l2_cropcap structure to the respective buffer (stream)
-type and call the :ref:`VIDIOC_CROPCAP` ioctl with a pointer to this
-structure. Drivers fill the rest of the structure. The results are
-constant except when switching the video standard. Remember this switch
-can occur implicit when switching the video input or output.
-
-This ioctl must be implemented for video capture or output devices that
-support cropping and/or scaling and/or have non-square pixels, and for
-overlay devices.

-      - ``type``
-      - Type of the data stream, set by the application. Only these types

-	``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE`` and

-      - ``bounds``
-      - Defines the window within capturing or output is possible, this
-	may exclude for example the horizontal and vertical blanking
-	areas. The cropping rectangle cannot exceed these limits. Width
-	and height are defined in pixels, the driver writer is free to
-	choose origin and units of the coordinate system in the analog
-	domain.
-    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
-      - ``defrect``
-      - Default cropping rectangle, it shall cover the "whole picture".
-	Assuming pixel aspect 1/1 this could be for example a 640 × 480
-	rectangle for NTSC, a 768 × 576 rectangle for PAL and SECAM
-	centered over the active picture area. The same co-ordinate system
-	as for ``bounds`` is used.
-    * - struct :c:type:`v4l2_fract`
-      - ``pixelaspect``
-      - This is the pixel aspect (y / x) when no scaling is applied, the
-	ratio of the actual sampling frequency and the frequency required
-	to get square pixels.
-
-	When cropping coordinates refer to square pixels, the driver sets
-	``pixelaspect`` to 1/1. Other common values are 54/59 for PAL and
-	SECAM, 11/10 for NTSC sampled according to [:ref:`itu601`].
-
-.. note::
-   Unfortunately in the case of multiplanar buffer types
-   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
-   this API was messed up with regards to how the :c:type:`v4l2_cropcap` ``type`` field
-   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
-   other drivers only accepted a non-multiplanar buffer type (i.e. without the
-   ``_MPLANE`` at the end).
-
-   Starting with kernel 4.13 both variations are allowed.

-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_dbg_chip_info`.
-
-
-Description
-===========
-
-.. note::
-
-    This is an :ref:`experimental` interface and may
-    change in the future.
-
-For driver debugging purposes this ioctl allows test applications to
-query the driver about the chips present on the TV card. Regular
-applications must not use it. When you found a chip specific bug, please
-contact the linux-media mailing list
-(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
-so it can be fixed.
-
-Additionally the Linux kernel must be compiled with the
-``CONFIG_VIDEO_ADV_DEBUG`` option to enable this ioctl.
-
-To query the driver applications must initialize the ``match.type`` and
-``match.addr`` or ``match.name`` fields of a struct
-:c:type:`v4l2_dbg_chip_info` and call
-:ref:`VIDIOC_DBG_G_CHIP_INFO` with a pointer to this structure. On success
-the driver stores information about the selected chip in the ``name``
-and ``flags`` fields.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
-selects the nth bridge 'chip' on the TV card. You can enumerate all
-chips by starting at zero and incrementing ``match.addr`` by one until
-:ref:`VIDIOC_DBG_G_CHIP_INFO` fails with an ``EINVAL`` error code. The number
-zero always selects the bridge chip itself, e. g. the chip connected to
-the PCI or USB bus. Non-zero numbers identify specific parts of the
-bridge chip such as an AC97 register block.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
-selects the nth sub-device. This allows you to enumerate over all
-sub-devices.
-
-On success, the ``name`` field will contain a chip name and the
-``flags`` field will contain ``V4L2_CHIP_FL_READABLE`` if the driver
-supports reading registers from the device or ``V4L2_CHIP_FL_WRITABLE``
-if the driver supports writing registers to the device.
-
-We recommended the v4l2-dbg utility over calling this ioctl directly. It
-is available from the LinuxTV v4l-dvb repository; see
-`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access

-
-    This is an :ref:`experimental` interface and may

-
-For driver debugging purposes these ioctls allow test applications to

-
-Since writing or even reading registers can jeopardize the system
-security, its stability and damage the hardware, both ioctls require
-superuser privileges. Additionally the Linux kernel must be compiled
-with the ``CONFIG_VIDEO_ADV_DEBUG`` option to enable these ioctls.
-
-To write a register applications must initialize all fields of a struct
-:c:type:`v4l2_dbg_register` except for ``size`` and
-call ``VIDIOC_DBG_S_REGISTER`` with a pointer to this structure. The
-``match.type`` and ``match.addr`` or ``match.name`` fields select a chip
-on the TV card, the ``reg`` field specifies a register number and the
-``val`` field the value to be written into the register.
-
-To read a register applications must initialize the ``match.type``,
-``match.addr`` or ``match.name`` and ``reg`` fields, and call
-``VIDIOC_DBG_G_REGISTER`` with a pointer to this structure. On success
-the driver stores the register value in the ``val`` field and the size
-(in bytes) of the value in ``size``.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
-selects the nth non-sub-device chip on the TV card. The number zero
-always selects the host chip, e. g. the chip connected to the PCI or USB
-bus. You can find out which chips are present with the
-:ref:`VIDIOC_DBG_G_CHIP_INFO` ioctl.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
-selects the nth sub-device.
-
-These ioctls are optional, not all drivers may support them. However
-when a driver supports these ioctls it must also support
-:ref:`VIDIOC_DBG_G_CHIP_INFO`. Conversely
-it may support ``VIDIOC_DBG_G_CHIP_INFO`` but not these ioctls.
-
-``VIDIOC_DBG_G_REGISTER`` and ``VIDIOC_DBG_S_REGISTER`` were introduced

-
-Description
-===========
-
-These ioctls control an audio/video (usually MPEG-) decoder.
-``VIDIOC_DECODER_CMD`` sends a command to the decoder,
-``VIDIOC_TRY_DECODER_CMD`` can be used to try a command without actually
-executing it. To send a command applications must initialize all fields
-of a struct :c:type:`v4l2_decoder_cmd` and call
-``VIDIOC_DECODER_CMD`` or ``VIDIOC_TRY_DECODER_CMD`` with a pointer to
-this structure.
-
-The ``cmd`` field must contain the command code. Some commands use the
-``flags`` field for additional information.
-
-A :ref:`write() <func-write>` or :ref:`VIDIOC_STREAMON`
-call sends an implicit START command to the decoder if it has not been
-started yet. Applies to both queues of mem2mem decoders.
-
-A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-call of a streaming file descriptor sends an implicit immediate STOP
-command to the decoder, and all buffered data is discarded. Applies to both
-queues of mem2mem decoders.
-
-In principle, these ioctls are optional, not all drivers may support them. They were
-introduced in Linux 3.3. They are, however, mandatory for stateful mem2mem decoders
-(as further documented in :ref:`decoder`).

-    * -
-      - __s32
-      - ``speed``
-      - Playback speed and direction. The playback speed is defined as
-	``speed``/1000 of the normal speed. So 1000 is normal playback.
-	Negative numbers denote reverse playback, so -1000 does reverse
-	playback at normal speed. Speeds -1, 0 and 1 have special
-	meanings: speed 0 is shorthand for 1000 (normal playback). A speed
-	of 1 steps just one frame forward, a speed of -1 steps just one
-	frame back.
-    * -
-      - __u32
-      - ``format``
-      - Format restrictions. This field is set by the driver, not the
-	application. Possible values are ``V4L2_DEC_START_FMT_NONE`` if
-	there are no format restrictions or ``V4L2_DEC_START_FMT_GOP`` if
-	the decoder operates on full GOPs (*Group Of Pictures*). This is
-	usually the case for reverse playback: the decoder needs full
-	GOPs, which it can then play in reverse order. So to implement
-	reverse playback the application must feed the decoder the last
-	GOP in the video file, then the GOP before that, etc. etc.

-      - ``pts``
-      - Stop playback at this ``pts`` or immediately if the playback is

-
-    * - ``V4L2_DEC_CMD_START``
-      - 0
-      - Start the decoder. When the decoder is already running or paused,
-	this command will just change the playback speed. That means that
-	calling ``V4L2_DEC_CMD_START`` when the decoder was paused will
-	*not* resume the decoder. You have to explicitly call
-	``V4L2_DEC_CMD_RESUME`` for that. This command has one flag:
-	``V4L2_DEC_CMD_START_MUTE_AUDIO``. If set, then audio will be
-	muted when playing back at a non-standard speed.
-
-	For a device implementing the :ref:`decoder`, once the drain sequence
-	is initiated with the ``V4L2_DEC_CMD_STOP`` command, it must be driven
-	to completion before this command can be invoked.  Any attempt to
-	invoke the command while the drain sequence is in progress will trigger
-	an ``EBUSY`` error code.  The command may be also used to restart the
-	decoder in case of an implicit stop initiated by the decoder itself,
-	without the ``V4L2_DEC_CMD_STOP`` being called explicitly. See
-	:ref:`decoder` for more details.
-    * - ``V4L2_DEC_CMD_STOP``
-      - 1
-      - Stop the decoder. When the decoder is already stopped, this
-	command does nothing. This command has two flags: if
-	``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set
-	the picture to black after it stopped decoding. Otherwise the last
-	image will repeat. If
-	``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops
-	immediately (ignoring the ``pts`` value), otherwise it will keep
-	decoding until timestamp >= pts or until the last of the pending
-	data from its internal buffers was decoded.
-
-	For a device implementing the :ref:`decoder`, the command will initiate
-	the drain sequence as documented in :ref:`decoder`.  No flags or other
-	arguments are accepted in this case. Any attempt to invoke the command
-	again before the sequence completes will trigger an ``EBUSY`` error
-	code.
-    * - ``V4L2_DEC_CMD_PAUSE``
-      - 2
-      - Pause the decoder. When the decoder has not been started yet, the
-	driver will return an ``EPERM`` error code. When the decoder is
-	already paused, this command does nothing. This command has one
-	flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the
-	decoder output to black when paused.
-    * - ``V4L2_DEC_CMD_RESUME``
-      - 3
-      - Resume decoding after a PAUSE command. When the decoder has not
-	been started yet, the driver will return an ``EPERM`` error code. When
-	the decoder is already running, this command does nothing. No
-	flags are defined for this command.
-    * - ``V4L2_DEC_CMD_FLUSH``
-      - 4
-      - Flush any held capture buffers. Only valid for stateless decoders.
-	This command is typically used when the application reached the
-	end of the stream and the last output buffer had the
-	``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag set. This would prevent
-	dequeueing the capture buffer containing the last decoded frame.
-	So this command can be used to explicitly flush that final decoded
-	frame. This command does nothing if there are no held capture buffers.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EBUSY
-    A drain sequence of a device implementing the :ref:`decoder` is still in
-    progress. It is not allowed to issue another decoder command until it
-    completes.
-
-EINVAL
-    The ``cmd`` field is invalid.
-
-EPERM
-    The application sent a PAUSE or RESUME command when the decoder was
-    not running.

-      - All events. V4L2_EVENT_ALL is valid only for
-	VIDIOC_UNSUBSCRIBE_EVENT for unsubscribing all events at once.
-    * - ``V4L2_EVENT_VSYNC``
-      - 1
-      - This event is triggered on the vertical sync. This event has a
-	struct :c:type:`v4l2_event_vsync` associated
-	with it.
-    * - ``V4L2_EVENT_EOS``
-      - 2
-      - This event is triggered when the end of a stream is reached. This
-	is typically used with MPEG decoders to report to the application
-	when the last of the MPEG stream has been decoded.
-    * - ``V4L2_EVENT_CTRL``
-      - 3
-      - This event requires that the ``id`` matches the control ID from
-	which you want to receive events. This event is triggered if the
-	control's value changes, if a button control is pressed or if the
-	control's flags change. This event has a struct
-	:c:type:`v4l2_event_ctrl` associated with it.
-	This struct contains much of the same information as struct
-	:ref:`v4l2_queryctrl <v4l2-queryctrl>` and struct
-	:c:type:`v4l2_control`.
-
-	If the event is generated due to a call to
-	:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` or
-	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then the
-	event will *not* be sent to the file handle that called the ioctl
-	function. This prevents nasty feedback loops. If you *do* want to
-	get the event, then set the ``V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK``
-	flag.
-
-	This event type will ensure that no information is lost when more
-	events are raised than there is room internally. In that case the
-	struct :c:type:`v4l2_event_ctrl` of the
-	second-oldest event is kept, but the ``changes`` field of the
-	second-oldest event is ORed with the ``changes`` field of the
-	oldest event.
-    * - ``V4L2_EVENT_FRAME_SYNC``
-      - 4
-      - Triggered immediately when the reception of a frame has begun.
-	This event has a struct
-	:c:type:`v4l2_event_frame_sync`
-	associated with it.
-
-	If the hardware needs to be stopped in the case of a buffer
-	underrun it might not be able to generate this event. In such
-	cases the ``frame_sequence`` field in struct
-	:c:type:`v4l2_event_frame_sync` will not
-	be incremented. This causes two consecutive frame sequence numbers
-	to have n times frame interval in between them.
-    * - ``V4L2_EVENT_SOURCE_CHANGE``
-      - 5
-      - This event is triggered when a source parameter change is detected
-	during runtime by the video device. It can be a runtime resolution
-	change triggered by a video decoder or the format change happening
-	on an input connector. This event requires that the ``id`` matches
-	the input index (when used with a video device node) or the pad
-	index (when used with a subdevice node) from which you want to
-	receive events.
-
-	This event has a struct
-	:c:type:`v4l2_event_src_change`
-	associated with it. The ``changes`` bitfield denotes what has
-	changed for the subscribed pad. If multiple events occurred before
-	application could dequeue them, then the changes will have the
-	ORed value of all the events generated.
-    * - ``V4L2_EVENT_MOTION_DET``
-      - 6
-      - Triggered whenever the motion detection state for one or more of
-	the regions changes. This event has a struct
-	:c:type:`v4l2_event_motion_det`
-	associated with it.
-    * - ``V4L2_EVENT_PRIVATE_START``

-
-Description
-===========
-
-To query the capabilities of the DV receiver/transmitter applications
-initialize the ``pad`` field to 0, zero the reserved array of struct
-:c:type:`v4l2_dv_timings_cap` and call the
-``VIDIOC_DV_TIMINGS_CAP`` ioctl on a video node and the driver will fill
-in the structure.
-
-.. note::
-
-   Drivers may return different values after
-   switching the video input or output.
-
-When implemented by the driver DV capabilities of subdevices can be
-queried by calling the ``VIDIOC_SUBDEV_DV_TIMINGS_CAP`` ioctl directly
-on a subdevice node. The capabilities are specific to inputs (for DV
-receivers) or outputs (for DV transmitters), applications must specify
-the desired pad number in the struct
-:c:type:`v4l2_dv_timings_cap` ``pad`` field and
-zero the ``reserved`` array. Attempts to query capabilities on a pad
-that doesn't support them will return an ``EINVAL`` error code.

-
-Description
-===========
-
-These ioctls control an audio/video (usually MPEG-) encoder.
-``VIDIOC_ENCODER_CMD`` sends a command to the encoder,
-``VIDIOC_TRY_ENCODER_CMD`` can be used to try a command without actually
-executing it.
-
-To send a command applications must initialize all fields of a struct
-:c:type:`v4l2_encoder_cmd` and call
-``VIDIOC_ENCODER_CMD`` or ``VIDIOC_TRY_ENCODER_CMD`` with a pointer to
-this structure.
-
-The ``cmd`` field must contain the command code. The ``flags`` field is
-currently only used by the STOP command and contains one bit: If the
-``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag is set, encoding will continue
-until the end of the current *Group Of Pictures*, otherwise it will stop
-immediately.
-
-A :ref:`read() <func-read>` or :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-call sends an implicit START command to the encoder if it has not been
-started yet. After a STOP command, :ref:`read() <func-read>` calls will read
-the remaining data buffered by the driver. When the buffer is empty,
-:ref:`read() <func-read>` will return zero and the next :ref:`read() <func-read>`
-call will restart the encoder.
-
-A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-call of a streaming file descriptor sends an implicit immediate STOP to
-the encoder, and all buffered data is discarded.
-
-These ioctls are optional, not all drivers may support them. They were
-introduced in Linux 2.6.21.

-Description
-===========
-
-While some DV receivers or transmitters support a wide range of timings,
-others support only a limited number of timings. With this ioctl
-applications can enumerate a list of known supported timings. Call
-:ref:`VIDIOC_DV_TIMINGS_CAP` to check if it
-also supports other standards or even custom timings that are not in
-this list.
-
-To query the available timings, applications initialize the ``index``
-field, set the ``pad`` field to 0, zero the reserved array of struct
-:c:type:`v4l2_enum_dv_timings` and call the
-``VIDIOC_ENUM_DV_TIMINGS`` ioctl on a video node with a pointer to this
-structure. Drivers fill the rest of the structure or return an ``EINVAL``
-error code when the index is out of bounds. To enumerate all supported
-DV timings, applications shall begin at index zero, incrementing by one
-until the driver returns ``EINVAL``.
-
-.. note::
-
-   Drivers may enumerate a different set of DV timings after
-   switching the video input or output.
-
-When implemented by the driver DV timings of subdevices can be queried
-by calling the ``VIDIOC_SUBDEV_ENUM_DV_TIMINGS`` ioctl directly on a
-subdevice node. The DV timings are specific to inputs (for DV receivers)
-or outputs (for DV transmitters), applications must specify the desired
-pad number in the struct
-:c:type:`v4l2_enum_dv_timings` ``pad`` field.
-Attempts to enumerate timings on a pad that doesn't support them will

-VIDIOC_ENUM_FRAMEINTERVALS - Enumerate frame intervals

-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_ENUM_FRAMEINTERVALS, struct v4l2_frmivalenum *argp )
-    :name: VIDIOC_ENUM_FRAMEINTERVALS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_frmivalenum`
-    that contains a pixel format and size and receives a frame interval.
-
-
-Description
-===========
-
-This ioctl allows applications to enumerate all frame intervals that the
-device supports for the given pixel format and frame size.
-
-The supported pixel formats and frame sizes can be obtained by using the
-:ref:`VIDIOC_ENUM_FMT` and
-:ref:`VIDIOC_ENUM_FRAMESIZES` functions.
-
-The return value and the content of the ``v4l2_frmivalenum.type`` field
-depend on the type of frame intervals the device supports. Here are the
-semantics of the function for the different cases:
-
--  **Discrete:** The function returns success if the given index value
-   (zero-based) is valid. The application should increase the index by
-   one for each call until ``EINVAL`` is returned. The
-   `v4l2_frmivalenum.type` field is set to
-   `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the union only
-   the `discrete` member is valid.
-
--  **Step-wise:** The function returns success if the given index value
-   is zero and ``EINVAL`` for any other index value. The
-   ``v4l2_frmivalenum.type`` field is set to
-   ``V4L2_FRMIVAL_TYPE_STEPWISE`` by the driver. Of the union only the
-   ``stepwise`` member is valid.
-
--  **Continuous:** This is a special case of the step-wise type above.
-   The function returns success if the given index value is zero and
-   ``EINVAL`` for any other index value. The ``v4l2_frmivalenum.type``
-   field is set to ``V4L2_FRMIVAL_TYPE_CONTINUOUS`` by the driver. Of
-   the union only the ``stepwise`` member is valid and the ``step``
-   value is set to 1.
-
-When the application calls the function with index zero, it must check
-the ``type`` field to determine the type of frame interval enumeration
-the device supports. Only for the ``V4L2_FRMIVAL_TYPE_DISCRETE`` type
-does it make sense to increase the index value to receive more frame
-intervals.
-
-.. note::
-
-   The order in which the frame intervals are returned has no
-   special meaning. In particular does it not say anything about potential
-   default frame intervals.
-
-Applications can assume that the enumeration data does not change
-without any interaction from the application itself. This means that the
-enumeration data is consistent if the application does not perform any
-other ioctl calls while it runs the frame interval enumeration.
-
-.. note::
-
-   **Frame intervals and frame rates:** The V4L2 API uses frame
-   intervals instead of frame rates. Given the frame interval the frame
-   rate can be computed as follows:
-
-   ::
-
-       frame_rate = 1 / frame_interval

-Description
-===========
-
-To query the attributes of a video standard, especially a custom (driver
-defined) one, applications initialize the ``index`` field of struct
-:c:type:`v4l2_standard` and call the :ref:`VIDIOC_ENUMSTD`
-ioctl with a pointer to this structure. Drivers fill the rest of the
-structure or return an ``EINVAL`` error code when the index is out of
-bounds. To enumerate all standards applications shall begin at index
-zero, incrementing by one until the driver returns ``EINVAL``. Drivers may
-enumerate a different set of standards after switching the video input
-or output. [#f1]_

-    * - __u32
-      - ``index``
-      - Number of the video standard, set by the application.
-    * - :ref:`v4l2_std_id <v4l2-std-id>`
-      - ``id``
-      - The bits in this field identify the standard as one of the common
-	standards listed in :ref:`v4l2-std-id`, or if bits 32 to 63 are
-	set as custom standards. Multiple bits can be set if the hardware
-	does not distinguish between these standards, however separate
-	indices do not indicate the opposite. The ``id`` must be unique.
-	No other enumerated struct :c:type:`v4l2_standard` structure,
-	for this input or output anyway, can contain the same set of bits.
-    * - __u8
-      - ``name``\ [24]
-      - Name of the standard, a NUL-terminated ASCII string, for example:
-	"PAL-B/G", "NTSC Japan". This information is intended for the
-	user.
-    * - struct :c:type:`v4l2_fract`
-      - ``frameperiod``
-      - The frame period (not field period) is numerator / denominator.
-	For example M/NTSC has a frame period of 1001 / 30000 seconds.
-    * - __u32

-VIDIOC_EXPBUF - Export a buffer as a DMABUF file descriptor.
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_EXPBUF, struct v4l2_exportbuffer *argp )
-    :name: VIDIOC_EXPBUF
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_exportbuffer`.
-
-
-Description
-===========
-
-This ioctl is an extension to the :ref:`memory mapping <mmap>` I/O
-method, therefore it is available only for ``V4L2_MEMORY_MMAP`` buffers.
-It can be used to export a buffer as a DMABUF file at any time after
-buffers have been allocated with the
-:ref:`VIDIOC_REQBUFS` ioctl.
-
-To export a buffer, applications fill struct
-:c:type:`v4l2_exportbuffer`. The ``type`` field is
-set to the same buffer type as was previously used with struct
-:c:type:`v4l2_requestbuffers` ``type``.
-Applications must also set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. For the multi-planar API, applications set the ``plane`` field to
-the index of the plane to be exported. Valid planes range from zero to
-the maximal number of valid planes for the currently active format. For
-the single-planar API, applications must set ``plane`` to zero.
-Additional flags may be posted in the ``flags`` field. Refer to a manual
-for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
-and O_RDWR are supported. All other fields must be set to zero. In the
-case of multi-planar API, every plane is exported separately using
-multiple :ref:`VIDIOC_EXPBUF` calls.
-
-After calling :ref:`VIDIOC_EXPBUF` the ``fd`` field will be set by a
-driver. This is a DMABUF file descriptor. The application may pass it to
-other DMABUF-aware devices. Refer to :ref:`DMABUF importing <dmabuf>`
-for details about importing DMABUF files into V4L2 nodes. It is
-recommended to close a DMABUF file when it is no longer used to allow
-the associated memory to be reclaimed.

-
-``argp``
-    Pointer to struct :c:type:`v4l2_crop`.
-
-
-Description
-===========
-
-To query the cropping rectangle size and position applications set the
-``type`` field of a struct :c:type:`v4l2_crop` structure to the
-respective buffer (stream) type and call the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` ioctl
-with a pointer to this structure. The driver fills the rest of the
-structure or returns the ``EINVAL`` error code if cropping is not supported.
-
-To change the cropping rectangle applications initialize the ``type``
-and struct :c:type:`v4l2_rect` substructure named ``c`` of a
-v4l2_crop structure and call the :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl with a pointer
-to this structure.
-
-The driver first adjusts the requested dimensions against hardware
-limits, i. e. the bounds given by the capture/output window, and it
-rounds to the closest possible values of horizontal and vertical offset,
-width and height. In particular the driver must round the vertical
-offset of the cropping rectangle to frame lines modulo two, such that
-the field order cannot be confused.
-
-Second the driver adjusts the image size (the opposite rectangle of the
-scaling process, source or target depending on the data direction) to
-the closest size possible while maintaining the current horizontal and
-vertical scaling factor.
-
-Finally the driver programs the hardware with the actual cropping and
-image parameters. :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` is a write-only ioctl, it does not
-return the actual parameters. To query them applications must call
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_G_FMT`. When the
-parameters are unsuitable the application may modify the cropping or
-image parameters and repeat the cycle until satisfactory parameters have
-been negotiated.
-
-When cropping is not supported then no parameters are changed and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` returns the ``EINVAL`` error code.

-   Unfortunately in the case of multiplanar buffer types
-   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
-   this API was messed up with regards to how the :c:type:`v4l2_crop` ``type`` field
-   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
-   other drivers only accepted a non-multiplanar buffer type (i.e. without the
-   ``_MPLANE`` at the end).
-
-   Starting with kernel 4.13 both variations are allowed.

-Description
-===========
-
-To set DV timings for the input or output, applications use the
-:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get the current timings,
-applications use the :ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. The detailed timing
-information is filled in using the structure struct
-:c:type:`v4l2_dv_timings`. These ioctls take a
-pointer to the struct :c:type:`v4l2_dv_timings`
-structure as argument. If the ioctl is not supported or the timing
-values are not correct, the driver returns ``EINVAL`` error code.
-
-The ``linux/v4l2-dv-timings.h`` header can be used to get the timings of
-the formats in the :ref:`cea861` and :ref:`vesadmt` standards. If
-the current input or output does not support DV timings (e.g. if
-:ref:`VIDIOC_ENUMINPUT` does not set the
-``V4L2_IN_CAP_DV_TIMINGS`` flag), then ``ENODATA`` error code is returned.
-
-
-Return Value

-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-
-    * - Flag
-      - Description
-    * - ``V4L2_DV_FL_REDUCED_BLANKING``
-      - CVT/GTF specific: the timings use reduced blanking (CVT) or the
-	'Secondary GTF' curve (GTF). In both cases the horizontal and/or
-	vertical blanking intervals are reduced, allowing a higher
-	resolution over the same bandwidth. This is a read-only flag,
-	applications must not set this.
-    * - ``V4L2_DV_FL_CAN_REDUCE_FPS``
-      - CEA-861 specific: set for CEA-861 formats with a framerate that is
-	a multiple of six. These formats can be optionally played at 1 /
-	1.001 speed to be compatible with 60 Hz based standards such as
-	NTSC and PAL-M that use a framerate of 29.97 frames per second. If
-	the transmitter can't generate such frequencies, then the flag
-	will also be cleared. This is a read-only flag, applications must
-	not set this.
-    * - ``V4L2_DV_FL_REDUCED_FPS``
-      - CEA-861 specific: only valid for video transmitters or video
-        receivers that have the ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
-	set. This flag is cleared otherwise. It is also only valid for
-	formats with the ``V4L2_DV_FL_CAN_REDUCE_FPS`` flag set, for other
-	formats the flag will be cleared by the driver.
-
-	If the application sets this flag for a transmitter, then the
-	pixelclock used to set up the transmitter is divided by 1.001 to
-	make it compatible with NTSC framerates. If the transmitter can't
-	generate such frequencies, then the flag will be cleared.
-
-	If a video receiver detects that the format uses a reduced framerate,
-	then it will set this flag to signal this to the application.
-    * - ``V4L2_DV_FL_HALF_LINE``
-      - Specific to interlaced formats: if set, then the vertical
-	frontporch of field 1 (aka the odd field) is really one half-line
-	longer and the vertical backporch of field 2 (aka the even field)
-	is really one half-line shorter, so each field has exactly the
-	same number of half-lines. Whether half-lines can be detected or
-	used depends on the hardware.
-    * - ``V4L2_DV_FL_IS_CE_VIDEO``
-      - If set, then this is a Consumer Electronics (CE) video format.
-	Such formats differ from other formats (commonly called IT
-	formats) in that if R'G'B' encoding is used then by default the
-	R'G'B' values use limited range (i.e. 16-235) as opposed to full
-	range (i.e. 0-255). All formats defined in CEA-861 except for the
-	640x480p59.94 format are CE formats.
-    * - ``V4L2_DV_FL_FIRST_FIELD_EXTRA_LINE``
-      - Some formats like SMPTE-125M have an interlaced signal with a odd
-	total height. For these formats, if this flag is set, the first
-	field has the extra line. Else, it is the second field.
-    * - ``V4L2_DV_FL_HAS_PICTURE_ASPECT``
-      - If set, then the picture_aspect field is valid. Otherwise assume that
-        the pixels are square, so the picture aspect ratio is the same as the
-	width to height ratio.
-    * - ``V4L2_DV_FL_HAS_CEA861_VIC``
-      - If set, then the cea861_vic field is valid and contains the Video
-        Identification Code as per the CEA-861 standard.
-    * - ``V4L2_DV_FL_HAS_HDMI_VIC``
-      - If set, then the hdmi_vic field is valid and contains the Video
-        Identification Code as per the HDMI standard (HDMI Vendor Specific
-	InfoFrame).
-    * - ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
-      - CEA-861 specific: only valid for video receivers, the flag is
-        cleared by transmitters.
-        If set, then the hardware can detect the difference between
-	regular framerates and framerates reduced by 1000/1001. E.g.:
-	60 vs 59.94 Hz, 30 vs 29.97 Hz or 24 vs 23.976 Hz.

-=========
-

-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-   Pointer to struct :c:type:`v4l2_edid`.
-
-
-Description
-===========
-
-These ioctls can be used to get or set an EDID associated with an input
-from a receiver or an output of a transmitter device. They can be used
-with subdevice nodes (/dev/v4l-subdevX) or with video nodes
-(/dev/videoX).
-
-When used with video nodes the ``pad`` field represents the input (for
-video capture devices) or output (for video output devices) index as is
-returned by :ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` respectively. When used
-with subdevice nodes the ``pad`` field represents the input or output
-pad of the subdevice. If there is no EDID support for the given ``pad``
-value, then the ``EINVAL`` error code will be returned.
-
-To get the EDID data the application has to fill in the ``pad``,
-``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
-array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
-``start_block`` and of size ``blocks`` will be placed in the memory
-``edid`` points to. The ``edid`` pointer must point to memory at least
-``blocks`` * 128 bytes large (the size of one block is 128 bytes).
-
-If there are fewer blocks than specified, then the driver will set
-``blocks`` to the actual number of blocks. If there are no EDID blocks
-available at all, then the error code ``ENODATA`` is set.
-
-If blocks have to be retrieved from the sink, then this call will block
-until they have been read.
-
-If ``start_block`` and ``blocks`` are both set to 0 when
-:ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
-total number of available EDID blocks and it will return 0 without
-copying any data. This is an easy way to discover how many EDID blocks
-there are.
-
-.. note::
-
-   If there are no EDID blocks available at all, then
-   the driver will set ``blocks`` to 0 and it returns 0.
-
-To set the EDID blocks of a receiver the application has to fill in the
-``pad``, ``blocks`` and ``edid`` fields, set ``start_block`` to 0 and
-zero the ``reserved`` array. It is not possible to set part of an EDID,
-it is always all or nothing. Setting the EDID data is only valid for
-receivers as it makes no sense for a transmitter.
-
-The driver assumes that the full EDID is passed in. If there are more
-EDID blocks than the hardware can handle then the EDID is not written,
-but instead the error code ``E2BIG`` is set and ``blocks`` is set to the
-maximum that the hardware supports. If ``start_block`` is any value
-other than 0 then the error code ``EINVAL`` is set.
-
-To disable an EDID you set ``blocks`` to 0. Depending on the hardware
-this will drive the hotplug pin low and/or block the source from reading
-the EDID data in some way. In any case, the end result is the same: the
-EDID is no longer available.

-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``

-
-
-Description
-===========
-
-The :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` ioctl provides meta data about a compressed
-video stream the same or another application currently reads from the
-driver, which is useful for random access into the stream without
-decoding it.
-
-To read the data applications must call :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` with a
-pointer to a struct :c:type:`v4l2_enc_idx`. On success
-the driver fills the ``entry`` array, stores the number of elements
-written in the ``entries`` field, and initializes the ``entries_cap``
-field.
-
-Each element of the ``entry`` array contains meta data about one
-picture. A :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` call reads up to
-``V4L2_ENC_IDX_ENTRIES`` entries from a driver buffer, which can hold up
-to ``entries_cap`` entries. This number can be lower or higher than
-``V4L2_ENC_IDX_ENTRIES``, but not zero. When the application fails to
-read the meta data in time the oldest entries will be lost. When the
-buffer is empty or no capturing/encoding is in progress, ``entries``
-will be zero.
-
-Currently this ioctl is only defined for MPEG-2 program streams and
-video elementary streams.

-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_ext_controls`.
-
-
-Description
-===========
-
-These ioctls allow the caller to get or set multiple controls
-atomically. Control IDs are grouped into control classes (see
-:ref:`ctrl-class`) and all controls in the control array must belong
-to the same control class.
-
-Applications must always fill in the ``count``, ``which``, ``controls``
-and ``reserved`` fields of struct
-:c:type:`v4l2_ext_controls`, and initialize the
-struct :c:type:`v4l2_ext_control` array pointed to
-by the ``controls`` fields.
-
-To get the current value of a set of controls applications initialize
-the ``id``, ``size`` and ``reserved2`` fields of each struct
-:c:type:`v4l2_ext_control` and call the
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. String controls controls must also set the
-``string`` field. Controls of compound types
-(``V4L2_CTRL_FLAG_HAS_PAYLOAD`` is set) must set the ``ptr`` field.
-
-If the ``size`` is too small to receive the control result (only
-relevant for pointer-type controls like strings), then the driver will
-set ``size`` to a valid value and return an ``ENOSPC`` error code. You
-should re-allocate the memory to this new size and try again. For the
-string type it is possible that the same issue occurs again if the
-string has grown in the meantime. It is recommended to call
-:ref:`VIDIOC_QUERYCTRL` first and use
-``maximum``\ +1 as the new ``size`` value. It is guaranteed that that is
-sufficient memory.
-
-N-dimensional arrays are set and retrieved row-by-row. You cannot set a
-partial array, all elements have to be set or retrieved. The total size
-is calculated as ``elems`` * ``elem_size``. These values can be obtained
-by calling :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>`.
-
-To change the value of a set of controls applications initialize the
-``id``, ``size``, ``reserved2`` and ``value/value64/string/ptr`` fields
-of each struct :c:type:`v4l2_ext_control` and call
-the :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. The controls will only be set if *all*
-control values are valid.
-
-To check if a set of controls have correct values applications
-initialize the ``id``, ``size``, ``reserved2`` and
-``value/value64/string/ptr`` fields of each struct
-:c:type:`v4l2_ext_control` and call the
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. It is up to the driver whether wrong
-values are automatically adjusted to a valid value or if an error is
-returned.
-
-When the ``id`` or ``which`` is invalid drivers return an ``EINVAL`` error
-code. When the value is out of bounds drivers can choose to take the
-closest valid value or return an ``ERANGE`` error code, whatever seems more
-appropriate. In the first case the new value is set in struct
-:c:type:`v4l2_ext_control`. If the new control value
-is inappropriate (e.g. the given menu index is not supported by the menu
-control), then this will also result in an ``EINVAL`` error code error.
-
-If ``request_fd`` is set to a not-yet-queued :ref:`request <media-request-api>`
-file descriptor and ``which`` is set to ``V4L2_CTRL_WHICH_REQUEST_VAL``,
-then the controls are not applied immediately when calling
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, but instead are applied by
-the driver for the buffer associated with the same request.
-If the device does not support requests, then ``EACCES`` will be returned.
-If requests are supported but an invalid request file descriptor is given,
-then ``EINVAL`` will be returned.
-
-An attempt to call :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
-request that has already been queued will result in an ``EBUSY`` error.
-
-If ``request_fd`` is specified and ``which`` is set to
-``V4L2_CTRL_WHICH_REQUEST_VAL`` during a call to
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then it will return the
-values of the controls at the time of request completion.
-If the request is not yet completed, then this will result in an
-``EACCES`` error.
-
-The driver will only set/get these controls if all control values are
-correct. This prevents the situation where only some of the controls
-were set/get. Only low-level errors (e. g. a failed i2c command) can
-still cause this situation.

-      - ``ctrl_class``
-      - The control class to which all controls belong, see

-	handling controls will also accept a value of 0 here, meaning that
-	the controls can belong to any control class. Whether drivers
-	support this can be tested by setting ``ctrl_class`` to 0 and

-	does not support requests, then ``EACCES`` will be returned.
-
-	.. note::
-
-	   When using ``V4L2_CTRL_WHICH_DEF_VAL`` be aware that you can only
-	   get the default value of the control, you cannot set or try it.
-
-	For backwards compatibility you can also use a control class here
-	(see :ref:`ctrl-class`). In that case all controls have to
-	belong to that control class. This usage is deprecated, instead
-	just use ``V4L2_CTRL_WHICH_CUR_VAL``. There are some very old
-	drivers that do not yet support ``V4L2_CTRL_WHICH_CUR_VAL`` and
-	that require a control class here. You can test for such drivers
-	by setting ctrl_class to ``V4L2_CTRL_WHICH_CUR_VAL`` and calling
-	VIDIOC_TRY_EXT_CTRLS with a count of 0. If that fails, then the
-	driver does not support ``V4L2_CTRL_WHICH_CUR_VAL``.
-    * - }
-      -
-    * - __u32
-      - ``count``
-      - The number of controls in the controls array. May also be zero.
-    * - __u32
-      - ``error_idx``
-      - Set by the driver in case of an error. If the error is associated
-	with a particular control, then ``error_idx`` is set to the index
-	of that control. If the error is not related to a specific
-	control, or the validation step failed (see below), then
-	``error_idx`` is set to ``count``. The value is undefined if the
-	ioctl returned 0 (success).
-
-	Before controls are read from/written to hardware a validation
-	step takes place: this checks if all controls in the list are
-	valid controls, if no attempt is made to write to a read-only
-	control or read from a write-only control, and any other up-front
-	checks that can be done without accessing the hardware. The exact
-	validations done during this step are driver dependent since some
-	checks might require hardware access for some devices, thus making
-	it impossible to do those checks up-front. However, drivers should
-	make a best-effort to do as many up-front checks as possible.
-
-	This check is done to avoid leaving the hardware in an
-	inconsistent state due to easy-to-avoid problems. But it leads to
-	another problem: the application needs to know whether an error
-	came from the validation step (meaning that the hardware was not
-	touched) or from an error during the actual reading from/writing
-	to hardware.
-
-	The, in hindsight quite poor, solution for that is to set
-	``error_idx`` to ``count`` if the validation failed. This has the
-	unfortunate side-effect that it is not possible to see which
-	control failed the validation. If the validation was successful
-	and the error happened while accessing the hardware, then
-	``error_idx`` is less than ``count`` and only the controls up to
-	``error_idx-1`` were read or written correctly, and the state of
-	the remaining controls is undefined.
-
-	Since :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` does not access hardware there is
-	also no need to handle the validation step in this special way, so
-	``error_idx`` will just be set to the control that failed the
-	validation step instead of to ``count``. This means that if
-	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` fails with ``error_idx`` set to ``count``,
-	then you can call :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` to try to discover the
-	actual control that failed the validation step. Unfortunately,
-	there is no ``TRY`` equivalent for :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.
-    * - __s32
-      - ``request_fd``
-      - File descriptor of the request to be used by this operation. Only
-	valid if ``which`` is set to ``V4L2_CTRL_WHICH_REQUEST_VAL``.
-	If the device does not support requests, then ``EACCES`` will be returned.
-	If requests are supported but an invalid request file descriptor is
-	given, then ``EINVAL`` will be returned.

-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    The struct :c:type:`v4l2_ext_control` ``id`` is
-    invalid, or the struct :c:type:`v4l2_ext_controls`
-    ``which`` is invalid, or the struct
-    :c:type:`v4l2_ext_control` ``value`` was
-    inappropriate (e.g. the given menu index is not supported by the
-    driver), or the ``which`` field was set to ``V4L2_CTRL_WHICH_REQUEST_VAL``
-    but the given ``request_fd`` was invalid or ``V4L2_CTRL_WHICH_REQUEST_VAL``
-    is not supported by the kernel.
-    This error code is also returned by the
-    :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctls if two or
-    more control values are in conflict.
-
-ERANGE
-    The struct :c:type:`v4l2_ext_control` ``value``
-    is out of bounds.
-
-EBUSY
-    The control is temporarily not changeable, possibly because another
-    applications took over control of the device function this control
-    belongs to, or (if the ``which`` field was set to
-    ``V4L2_CTRL_WHICH_REQUEST_VAL``) the request was queued but not yet
-    completed.
-
-ENOSPC
-    The space reserved for the control's payload is insufficient. The
-    field ``size`` is set to a value that is enough to store the payload
-    and this error code is returned.
-
-EACCES
-    Attempt to try or set a read-only control, or to get a write-only
-    control, or to get a control from a request that has not yet been
-    completed.
-
-    Or the ``which`` field was set to ``V4L2_CTRL_WHICH_REQUEST_VAL`` but the
-    device does not support requests.

-Description
-===========
-
-Applications can use the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl
-to get and set the framebuffer parameters for a
-:ref:`Video Overlay <overlay>` or :ref:`Video Output Overlay <osd>`
-(OSD). The type of overlay is implied by the device type (capture or
-output device) and can be determined with the
-:ref:`VIDIOC_QUERYCAP` ioctl. One ``/dev/videoN``
-device must not support both kinds of overlay.
-
-The V4L2 API distinguishes destructive and non-destructive overlays. A
-destructive overlay copies captured video images into the video memory
-of a graphics card. A non-destructive overlay blends video images into a
-VGA signal or graphics into a video signal. *Video Output Overlays* are
-always non-destructive.
-
-To get the current parameters applications call the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-ioctl with a pointer to a struct :c:type:`v4l2_framebuffer`
-structure. The driver fills all fields of the structure or returns an
-EINVAL error code when overlays are not supported.
-
-To set the parameters for a *Video Output Overlay*, applications must
-initialize the ``flags`` field of a struct
-:c:type:`v4l2_framebuffer`. Since the framebuffer is
-implemented on the TV card all other parameters are determined by the
-driver. When an application calls :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` with a pointer to
-this structure, the driver prepares for the overlay and returns the
-framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` does, or it returns an error
-code.
-
-To set the parameters for a *non-destructive Video Overlay*,
-applications must initialize the ``flags`` field, the ``fmt``
-substructure, and call :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. Again the driver prepares for
-the overlay and returns the framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-does, or it returns an error code.
-
-For a *destructive Video Overlay* applications must additionally provide
-a ``base`` address. Setting up a DMA to a random memory location can
-jeopardize the system security, its stability or even damage the
-hardware, therefore only the superuser can set the parameters for a
-destructive video overlay.

-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_format`.
-
-
-Description
-===========
-
-These ioctls are used to negotiate the format of data (typically image
-format) exchanged between driver and application.
-
-To query the current parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to the respective buffer (stream)
-type. For example video capture devices use
-``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
-``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. When the application calls the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this structure the driver fills
-the respective member of the ``fmt`` union. In case of video capture
-devices that is either the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member. When the requested buffer type is not supported drivers return
-an ``EINVAL`` error code.
-
-To change the current format parameters applications initialize the
-``type`` field and all fields of the respective ``fmt`` union member.
-For details see the documentation of the various devices types in
-:ref:`devices`. Good practice is to query the current parameters
-first, and to modify only those parameters not suitable for the
-application. When the application calls the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with
-a pointer to a struct :c:type:`v4l2_format` structure the driver
-checks and adjusts the parameters against hardware abilities. Drivers
-should not return an error code unless the ``type`` field is invalid,
-this is a mechanism to fathom device capabilities and to approach
-parameters acceptable for both the application and driver. On success
-the driver may program the hardware, allocate resources and generally
-prepare for data exchange. Finally the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl returns
-the current format parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Very simple,
-inflexible devices may even ignore all input and always return the
-default parameters. However all V4L2 devices exchanging data with the
-application must implement the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl. When the requested buffer type is not supported drivers return an
-EINVAL error code on a :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` attempt. When I/O is already in
-progress or the resource is not available for other reasons drivers
-return the ``EBUSY`` error code.
-
-The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl is equivalent to :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` with one
-exception: it does not change driver state. It can also be called at any
-time, never returning ``EBUSY``. This function is provided to negotiate
-parameters, to learn about hardware limitations, without disabling I/O
-or possibly time consuming hardware preparations. Although strongly
-recommended drivers are not required to implement this ioctl.
-
-The format as returned by :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` must be identical to what
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` returns for the same input or output.

-
-To get the current tuner or modulator radio frequency applications set

-
-To change the current tuner or modulator radio frequency applications
-initialize the ``tuner``, ``type`` and ``frequency`` fields, and the
-``reserved`` array of a struct :c:type:`v4l2_frequency`
-and call the :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this
-structure. When the requested frequency is not possible the driver
-assumes the closest possible value. However :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` is a
-write-only ioctl, it does not return the actual new frequency.

-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer an integer with input index.
-
-
-Description
-===========
-
-To query the current video input applications call the
-:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` ioctl with a pointer to an integer where the driver
-stores the number of the input, as in the struct
-:c:type:`v4l2_input` ``index`` field. This ioctl will fail
-only when there are no video inputs, returning ``EINVAL``.
-
-To select a video input applications store the number of the desired
-input in an integer and call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` ioctl with a pointer
-to this integer. Side effects are possible. For example inputs may
-support different video standards, so the driver may implicitly switch
-the current standard. Because of these possible side effects
-applications must select an input before querying or negotiating any
-other parameters.
-
-Information about video inputs is available using the
-:ref:`VIDIOC_ENUMINPUT` ioctl.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    The number of the video input is out of bounds.

-[to do]
-
-Ronald Bultje elaborates:
-
-APP is some application-specific information. The application can set it
-itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
-information for in an AVI or so). COM is the same, but it's comments,
-like 'encoded by me' or so.
-
-jpeg_markers describes whether the huffman tables, quantization tables
-and the restart interval information (all JPEG-specific stuff) should be
-stored in the JPEG-encoded fields. These define how the JPEG field is
-encoded. If you omit them, applications assume you've used standard
-encoding. You usually do want to add them.

-
-
-Description
-===========
-
-To query the attributes of a modulator applications initialize the
-``index`` field and zero out the ``reserved`` array of a struct
-:c:type:`v4l2_modulator` and call the
-:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl with a pointer to this structure. Drivers
-fill the rest of the structure or return an ``EINVAL`` error code when the
-index is out of bounds. To enumerate all modulators applications shall
-begin at index zero, incrementing by one until the driver returns
-EINVAL.
-
-Modulators have two writable properties, an audio modulation set and the
-radio frequency. To change the modulated audio subprograms, applications
-initialize the ``index`` and ``txsubchans`` fields and the ``reserved``
-array and call the :ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Drivers may choose a
-different audio modulation if the request cannot be satisfied. However
-this is a write-only ioctl, it does not return the actual audio
-modulation selected.
-
-:ref:`SDR <sdr>` specific modulator types are ``V4L2_TUNER_SDR`` and
-``V4L2_TUNER_RF``. For SDR devices ``txsubchans`` field must be
-initialized to zero. The term 'modulator' means SDR transmitter in this
-context.
-
-To change the radio frequency the
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

-Description
-===========
-
-The current video standard determines a nominal number of frames per
-second. If less than this number of frames is to be captured or output,
-applications can request frame skipping or duplicating on the driver
-side. This is especially useful when using the :ref:`read() <func-read>` or
-:ref:`write() <func-write>`, which are not augmented by timestamps or sequence
-counters, and to avoid unnecessary data copying.
-
-Changing the frame interval shall never change the format. Changing the
-format, on the other hand, may change the frame interval.
-
-Further these ioctls can be used to determine the number of buffers used
-internally by a driver in read/write mode. For implications see the
-section discussing the :ref:`read() <func-read>` function.
-
-To get and set the streaming parameters applications call the
-:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take a
-pointer to a struct :c:type:`v4l2_streamparm` which contains a

-
-	-  The driver may support fewer pixel formats than motion capture
-	   (eg; true color).
-
-	-  The driver may capture and arithmetically combine multiple
-	   successive fields or frames to remove color edge artifacts and
-	   reduce the noise in the video data.
-
-	-  The driver may capture images in slices like a scanner in order
-	   to handle larger format images than would otherwise be
-	   possible.
-
-	-  An image capture operation may be significantly slower than
-	   motion capture.
-
-	-  Moving objects in the image might have excessive motion blur.
-
-	-  Capture might only work through the :ref:`read() <func-read>` call.

-
-Description
-===========
-
-The ioctls are used to query and configure selection rectangles.
-
-To query the cropping (composing) rectangle set struct
-:c:type:`v4l2_selection` ``type`` field to the
-respective buffer type. The next step is setting the
-value of struct :c:type:`v4l2_selection` ``target``
-field to ``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer
-to table :ref:`v4l2-selections-common` or :ref:`selection-api` for
-additional targets. The ``flags`` and ``reserved`` fields of struct
-:c:type:`v4l2_selection` are ignored and they must be
-filled with zeros. The driver fills the rest of the structure or returns
-EINVAL error code if incorrect buffer type or target was used. If
-cropping (composing) is not supported then the active rectangle is not
-mutable and it is always equal to the bounds rectangle. Finally, the
-struct :c:type:`v4l2_rect` ``r`` rectangle is filled with
-the current cropping (composing) coordinates. The coordinates are
-expressed in driver-dependent units. The only exception are rectangles
-for images in raw formats, whose coordinates are always expressed in
-pixels.
-
-To change the cropping (composing) rectangle set the struct
-:c:type:`v4l2_selection` ``type`` field to the
-respective buffer type. The next step is setting the
-value of struct :c:type:`v4l2_selection` ``target`` to
-``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer to table
-:ref:`v4l2-selections-common` or :ref:`selection-api` for additional
-targets. The struct :c:type:`v4l2_rect` ``r`` rectangle need
-to be set to the desired active area. Field struct
-:c:type:`v4l2_selection` ``reserved`` is ignored and
-must be filled with zeros. The driver may adjust coordinates of the
-requested rectangle. An application may introduce constraints to control
-rounding behaviour. The struct :c:type:`v4l2_selection`
-``flags`` field must be set to one of the following:
-
--  ``0`` - The driver can adjust the rectangle size freely and shall
-   choose a crop/compose rectangle as close as possible to the requested
-   one.
-
--  ``V4L2_SEL_FLAG_GE`` - The driver is not allowed to shrink the
-   rectangle. The original rectangle must lay inside the adjusted one.
-
--  ``V4L2_SEL_FLAG_LE`` - The driver is not allowed to enlarge the
-   rectangle. The adjusted rectangle must lay inside the original one.
-
--  ``V4L2_SEL_FLAG_GE | V4L2_SEL_FLAG_LE`` - The driver must choose the
-   size exactly the same as in the requested rectangle.
-
-Please refer to :ref:`sel-const-adjust`.
-
-The driver may have to adjusts the requested dimensions against hardware
-limits and other parts as the pipeline, i.e. the bounds given by the
-capture/output window or TV display. The closest possible values of
-horizontal and vertical offset and sizes are chosen according to
-following priority:
-
-1. Satisfy constraints from struct
-   :c:type:`v4l2_selection` ``flags``.
-
-2. Adjust width, height, left, and top to hardware limits and
-   alignments.
-
-3. Keep center of adjusted rectangle as close as possible to the
-   original one.
-
-4. Keep width and height as close as possible to original ones.
-
-5. Keep horizontal and vertical offset as close as possible to original
-   ones.
-
-On success the struct :c:type:`v4l2_rect` ``r`` field
-contains the adjusted rectangle. When the parameters are unsuitable the
-application may modify the cropping (composing) or image parameters and
-repeat the cycle until satisfactory parameters have been negotiated. If
-constraints flags have to be violated at then ``ERANGE`` is returned. The
-error indicates that *there exist no rectangle* that satisfies the
-constraints.

-
-:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` accepts one or more flags, being a write-only ioctl it

-    Pointer to struct :c:type:`v4l2_tuner`.
-
-
-Description
-===========
-
-To query the attributes of a tuner applications initialize the ``index``
-field and zero out the ``reserved`` array of a struct
-:c:type:`v4l2_tuner` and call the ``VIDIOC_G_TUNER`` ioctl
-with a pointer to this structure. Drivers fill the rest of the structure
-or return an ``EINVAL`` error code when the index is out of bounds. To
-enumerate all tuners applications shall begin at index zero,
-incrementing by one until the driver returns ``EINVAL``.
-
-Tuners have two writable properties, the audio mode and the radio
-frequency. To change the audio mode, applications initialize the
-``index``, ``audmode`` and ``reserved`` fields and call the
-``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
-which is determined by the current video input. Drivers may choose a
-different audio mode if the requested mode is invalid or unsupported.
-Since this is a write-only ioctl, it does not return the actually
-selected audio mode.
-
-:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
-``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
-to zero. The term 'tuner' means SDR receiver in this context.
-
-To change the radio frequency the
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

-
-	Tuner capability flags, see :ref:`tuner-capability`. Audio flags
-	indicate the ability to decode audio subprograms. They will *not*
-	change, for example with the current video standard.
-
-	When the structure refers to a radio tuner the
-	``V4L2_TUNER_CAP_LANG1``, ``V4L2_TUNER_CAP_LANG2`` and
-	``V4L2_TUNER_CAP_NORM`` flags can't be used.
-
-	If multiple frequency bands are supported, then ``capability`` is
-	the union of all ``capability`` fields of each struct
-	:c:type:`v4l2_frequency_band`.
-    * - __u32
-      - ``rangelow``
-      - :cspan:`1` The lowest tunable frequency in units of 62.5 kHz, or
-	if the ``capability`` flag ``V4L2_TUNER_CAP_LOW`` is set, in units
-	of 62.5 Hz, or if the ``capability`` flag ``V4L2_TUNER_CAP_1HZ``
-	is set, in units of 1 Hz. If multiple frequency bands are
-	supported, then ``rangelow`` is the lowest frequency of all the
-	frequency bands.
-    * - __u32
-      - ``rangehigh``
-      - :cspan:`1` The highest tunable frequency in units of 62.5 kHz,

-	frequency of all the frequency bands.
-    * - __u32
-      - ``rxsubchans``
-      - :cspan:`1`
-
-	Some tuners or audio decoders can determine the received audio
-	subprograms by analyzing audio carriers, pilot tones or other
-	indicators. To pass this information drivers set flags defined in
-	:ref:`tuner-rxsubchans` in this field. For example:
-    * -
-      -
-      - ``V4L2_TUNER_SUB_MONO``
-      - receiving mono audio
-    * -
-      -
-      - ``STEREO | SAP``
-      - receiving stereo audio and a secondary audio program
-    * -
-      -
-      - ``MONO | STEREO``
-      - receiving mono or stereo audio, the hardware cannot distinguish
-    * -
-      -
-      - ``LANG1 | LANG2``
-      - receiving bilingual audio
-    * -
-      -
-      - ``MONO | STEREO | LANG1 | LANG2``
-      - receiving mono, stereo or bilingual audio
-    * -
-      -
-      - :cspan:`1`
-
-	When the ``V4L2_TUNER_CAP_STEREO``, ``_LANG1``, ``_LANG2`` or
-	``_SAP`` flag is cleared in the ``capability`` field, the
-	corresponding ``V4L2_TUNER_SUB_`` flag must not be set here.
-
-	This field is valid only if this is the tuner of the current video
-	input, or when the structure refers to a radio tuner.
-    * - __u32
-      - ``audmode``
-      - :cspan:`1`
-
-	The selected audio mode, see :ref:`tuner-audmode` for valid
-	values. The audio mode does not affect audio subprogram detection,
-	and like a :ref:`control` it does not automatically
-	change unless the requested mode is invalid or unsupported. See
-	:ref:`tuner-matrix` for possible results when the selected and
-	received audio programs do not match.
-
-	Currently this is the only field of struct
-	struct :c:type:`v4l2_tuner` applications can change.
-    * - __u32
-      - ``signal``
-      - :cspan:`1` The signal strength if known.
-
-	Ranging from 0 to 65535. Higher values indicate a better signal.
-    * - __s32
-      - ``afc``

-
-	When the ``afc`` value is negative, the frequency is too
-	low, when positive too high.
-    * - __u32
-      - ``reserved``\ [4]
-      - :cspan:`1` Reserved for future extensions.

-
-Description
-===========
-
-As the video/audio devices become more complicated it becomes harder to
-debug problems. When this ioctl is called the driver will output the
-current device status to the kernel log. This is particular useful when
-dealing with problems like no sound, no video and incorrectly tuned
-channels. Also many modern devices autodetect video and audio standards
-and this ioctl will report what the device thinks what the standard is.
-Mismatches may give an indication where the problem is.
-
-This ioctl is optional and not all drivers support it. It was introduced
-in Linux 2.6.15.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the

-

-    Pointer to struct :c:type:`v4l2_buffer`.
-
-
-Description
-===========
-
-Applications call the ``VIDIOC_QBUF`` ioctl to enqueue an empty
-(capturing) or filled (output) buffer in the driver's incoming queue.
-The semantics depend on the selected I/O method.
-
-To enqueue a buffer applications set the ``type`` field of a struct
-:c:type:`v4l2_buffer` to the same buffer type as was
-previously used with struct :c:type:`v4l2_format` ``type``
-and struct :c:type:`v4l2_requestbuffers` ``type``.
-Applications must also set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. The contents of the struct :c:type:`v4l2_buffer` returned
-by a :ref:`VIDIOC_QUERYBUF` ioctl will do as well.
-When the buffer is intended for output (``type`` is
-``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``,
-or ``V4L2_BUF_TYPE_VBI_OUTPUT``) applications must also initialize the
-``bytesused``, ``field`` and ``timestamp`` fields, see :ref:`buffer`
-for details. Applications must also set ``flags`` to 0. The
-``reserved2`` and ``reserved`` fields must be set to 0. When using the
-:ref:`multi-planar API <planar-apis>`, the ``m.planes`` field must
-contain a userspace pointer to a filled-in array of struct
-:c:type:`v4l2_plane` and the ``length`` field must be set
-to the number of elements in that array.
-
-To enqueue a :ref:`memory mapped <mmap>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_MMAP``. When ``VIDIOC_QBUF`` is called
-with a pointer to this structure the driver sets the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_QUEUED`` flags and clears
-the ``V4L2_BUF_FLAG_DONE`` flag in the ``flags`` field, or it returns an
-``EINVAL`` error code.
-
-To enqueue a :ref:`user pointer <userp>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_USERPTR``, the ``m.userptr`` field to
-the address of the buffer and ``length`` to its size. When the
-multi-planar API is used, ``m.userptr`` and ``length`` members of the
-passed array of struct :c:type:`v4l2_plane` have to be used
-instead. When ``VIDIOC_QBUF`` is called with a pointer to this structure
-the driver sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
-``flags`` field, or it returns an error code. This ioctl locks the
-memory pages of the buffer in physical memory, they cannot be swapped
-out to disk. Buffers remain locked until dequeued, until the
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
-:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
-device is closed.
-
-To enqueue a :ref:`DMABUF <dmabuf>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_DMABUF`` and the ``m.fd`` field to a
-file descriptor associated with a DMABUF buffer. When the multi-planar
-API is used the ``m.fd`` fields of the passed array of struct
-:c:type:`v4l2_plane` have to be used instead. When
-``VIDIOC_QBUF`` is called with a pointer to this structure the driver
-sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
-``flags`` field, or it returns an error code. This ioctl locks the
-buffer. Locking a buffer means passing it to a driver for a hardware
-access (usually DMA). If an application accesses (reads/writes) a locked
-buffer then the result is undefined. Buffers remain locked until
-dequeued, until the :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
-:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
-device is closed.
-
-The ``request_fd`` field can be used with the ``VIDIOC_QBUF`` ioctl to specify
-the file descriptor of a :ref:`request <media-request-api>`, if requests are
-in use. Setting it means that the buffer will not be passed to the driver
-until the request itself is queued. Also, the driver will apply any
-settings associated with the request for this buffer. This field will
-be ignored unless the ``V4L2_BUF_FLAG_REQUEST_FD`` flag is set.
-If the device does not support requests, then ``EBADR`` will be returned.
-If requests are supported but an invalid request file descriptor is given,
-then ``EINVAL`` will be returned.
-
-.. caution::
-   It is not allowed to mix queuing requests with queuing buffers directly.
-   ``EBUSY`` will be returned if the first buffer was queued directly and
-   then the application tries to queue a request, or vice versa. After
-   closing the file descriptor, calling
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or calling :ref:`VIDIOC_REQBUFS`
-   the check for this will be reset.
-
-   For :ref:`memory-to-memory devices <mem2mem>` you can specify the
-   ``request_fd`` only for output buffers, not for capture buffers. Attempting
-   to specify this for a capture buffer will result in an ``EBADR`` error.
-
-Applications call the ``VIDIOC_DQBUF`` ioctl to dequeue a filled
-(capturing) or displayed (output) buffer from the driver's outgoing
-queue. They just set the ``type``, ``memory`` and ``reserved`` fields of
-a struct :c:type:`v4l2_buffer` as above, when
-``VIDIOC_DQBUF`` is called with a pointer to this structure the driver
-fills the remaining fields or returns an error code. The driver may also
-set ``V4L2_BUF_FLAG_ERROR`` in the ``flags`` field. It indicates a
-non-critical (recoverable) streaming error. In such case the application
-may continue as normal, but should be aware that data in the dequeued
-buffer might be corrupted. When using the multi-planar API, the planes
-array must be passed in as well.
-
-If the application sets the ``memory`` field to ``V4L2_MEMORY_DMABUF`` to
-dequeue a :ref:`DMABUF <dmabuf>` buffer, the driver fills the ``m.fd`` field
-with a file descriptor numerically the same as the one given to ``VIDIOC_QBUF``
-when the buffer was enqueued. No new file descriptor is created at dequeue time
-and the value is only for the application convenience. When the multi-planar
-API is used the ``m.fd`` fields of the passed array of struct
-:c:type:`v4l2_plane` are filled instead.
-
-By default ``VIDIOC_DQBUF`` blocks when no buffer is in the outgoing
-queue. When the ``O_NONBLOCK`` flag was given to the
-:ref:`open() <func-open>` function, ``VIDIOC_DQBUF`` returns
-immediately with an ``EAGAIN`` error code when no buffer is available.
-
-The struct :c:type:`v4l2_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EAGAIN
-    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
-    buffer was in the outgoing queue.
-
-EINVAL
-    The buffer ``type`` is not supported, or the ``index`` is out of
-    bounds, or no buffers have been allocated yet, or the ``userptr`` or
-    ``length`` are invalid, or the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was
-    set but the the given ``request_fd`` was invalid, or ``m.fd`` was
-    an invalid DMABUF file descriptor.
-
-EIO
-    ``VIDIOC_DQBUF`` failed due to an internal error. Can also indicate
-    temporary problems like signal loss.
-
-    .. note::
-
-       The driver might dequeue an (empty) buffer despite returning
-       an error, or even stop capturing. Reusing such buffer may be unsafe
-       though and its details (e.g. ``index``) may not be returned either.
-       It is recommended that drivers indicate recoverable errors by setting
-       the ``V4L2_BUF_FLAG_ERROR`` and returning 0 instead. In that case the
-       application should be able to safely reuse the buffer and continue
-       streaming.
-
-EPIPE
-    ``VIDIOC_DQBUF`` returns this on an empty capture queue for mem2mem
-    codecs if a buffer with the ``V4L2_BUF_FLAG_LAST`` was already
-    dequeued and no new buffers are expected to become available.
-
-EBADR
-    The ``V4L2_BUF_FLAG_REQUEST_FD`` flag was set but the device does not
-    support requests for the given buffer type, or
-    the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was not set but the device requires
-    that the buffer is part of a request.
-
-EBUSY
-    The first buffer was queued via a request, but the application now tries
-    to queue it directly, or vice versa (it is not permitted to mix the two
-    APIs).

-
-Description
-===========
-
-The hardware may be able to detect the current DV timings automatically,
-similar to sensing the video standard. To do so, applications call
-:ref:`VIDIOC_QUERY_DV_TIMINGS` with a pointer to a struct
-:c:type:`v4l2_dv_timings`. Once the hardware detects
-the timings, it will fill in the timings structure.
-
-.. note::
-
-   Drivers shall *not* switch timings automatically if new
-   timings are detected. Instead, drivers should send the
-   ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support this) and expect
-   that userspace will take action by calling :ref:`VIDIOC_QUERY_DV_TIMINGS`.
-   The reason is that new timings usually mean different buffer sizes as
-   well, and you cannot change buffer sizes on the fly. In general,
-   applications that receive the Source Change event will have to call
-   :ref:`VIDIOC_QUERY_DV_TIMINGS`, and if the detected timings are valid they
-   will have to stop streaming, set the new timings, allocate new buffers
-   and start streaming again.
-
-If the timings could not be detected because there was no signal, then
-ENOLINK is returned. If a signal was detected, but it was unstable and
-the receiver could not lock to the signal, then ``ENOLCK`` is returned. If
-the receiver could lock to the signal, but the format is unsupported
-(e.g. because the pixelclock is out of range of the hardware
-capabilities), then the driver fills in whatever timings it could find
-and returns ``ERANGE``. In that case the application can call
-:ref:`VIDIOC_DV_TIMINGS_CAP` to compare the
-found timings with the hardware's capabilities in order to give more
-precise feedback to the user.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-ENODATA
-    Digital video timings are not supported for this input or output.
-
-ENOLINK
-    No timings could be detected because no signal was found.
-
-ENOLCK
-    The signal was unstable and the hardware could not lock on to it.
-
-ERANGE
-    Timings were found, but they are out of range of the hardware
-    capabilities.

-Description
-===========
-
-This ioctl is part of the :ref:`streaming <mmap>` I/O method. It can
-be used to query the status of a buffer at any time after buffers have
-been allocated with the :ref:`VIDIOC_REQBUFS` ioctl.
-
-Applications set the ``type`` field of a struct
-:c:type:`v4l2_buffer` to the same buffer type as was
-previously used with struct :c:type:`v4l2_format` ``type``
-and struct :c:type:`v4l2_requestbuffers` ``type``,
-and the ``index`` field. Valid index numbers range from zero to the
-number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. The ``reserved`` and ``reserved2`` fields must be set to 0. When
-using the :ref:`multi-planar API <planar-apis>`, the ``m.planes``
-field must contain a userspace pointer to an array of struct
-:c:type:`v4l2_plane` and the ``length`` field has to be set
-to the number of elements in that array. After calling
-:ref:`VIDIOC_QUERYBUF` with a pointer to this structure drivers return an
-error code or fill the rest of the structure.
-
-In the ``flags`` field the ``V4L2_BUF_FLAG_MAPPED``,
-``V4L2_BUF_FLAG_PREPARED``, ``V4L2_BUF_FLAG_QUEUED`` and
-``V4L2_BUF_FLAG_DONE`` flags will be valid. The ``memory`` field will be
-set to the current I/O method. For the single-planar API, the
-``m.offset`` contains the offset of the buffer from the start of the
-device memory, the ``length`` field its size. For the multi-planar API,
-fields ``m.mem_offset`` and ``length`` in the ``m.planes`` array
-elements will be used instead and the ``length`` field of struct
-:c:type:`v4l2_buffer` is set to the number of filled-in
-array elements. The driver may or may not set the remaining fields and
-flags, they are meaningless in this context.
-
-The struct :c:type:`v4l2_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value

-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-Description
-===========
-
-All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to
-identify kernel devices compatible with this specification and to obtain
-information about driver and hardware capabilities. The ioctl takes a
-pointer to a struct :c:type:`v4l2_capability` which is
-filled by the driver. When the driver is not compatible with this
-specification the ioctl returns an ``EINVAL`` error code.

-
-    * - __u8
-      - ``driver``\ [16]
-      - Name of the driver, a unique NUL-terminated ASCII string. For
-	example: "bttv". Driver specific applications can use this
-	information to verify the driver identity. It is also useful to
-	work around known bugs, or to identify drivers in error reports.
-
-	Storing strings in fixed sized arrays is bad practice but
-	unavoidable here. Drivers and applications should take precautions
-	to never read or write beyond the end of the array and to make
-	sure the strings are properly NUL-terminated.
-    * - __u8
-      - ``card``\ [32]
-      - Name of the device, a NUL-terminated UTF-8 string. For example:
-	"Yoyodyne TV/FM". One driver may support different brands or
-	models of video hardware. This information is intended for users,
-	for example in a menu of available devices. Since multiple TV
-	cards of the same brand may be installed which are supported by
-	the same driver, this name should be combined with the character
-	device file name (e. g. ``/dev/video2``) or the ``bus_info``
-	string to avoid ambiguities.
-    * - __u8
-      - ``bus_info``\ [32]
-      - Location of the device in the system, a NUL-terminated ASCII
-	string. For example: "PCI:0000:05:06.0". This information is
-	intended for users, to distinguish multiple identical devices. If
-	no such information is available the field must simply count the
-	devices controlled by the driver ("platform:vivi-000"). The
-	bus_info must start with "PCI:" for PCI boards, "PCIe:" for PCI
-	Express boards, "usb-" for USB devices, "I2C:" for i2c devices,
-	"ISA:" for ISA devices, "parport" for parallel port devices and
-	"platform:" for platform devices.
-    * - __u32
-      - ``version``
-      - Version number of the driver.
-
-	Starting with kernel 3.1, the version reported is provided by the
-	V4L2 subsystem following the kernel numbering scheme. However, it
-	may not always return the same version as the kernel if, for
-	example, a stable or distribution-modified kernel uses the V4L2
-	stack from a newer kernel.
-
-	The version number is formatted using the ``KERNEL_VERSION()``
-	macro. For example if the media stack corresponds to the V4L2
-	version shipped with Kernel 4.14, it would be equivalent to:
-    * - :cspan:`2`
-
-	``#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))``
-
-	``__u32 version = KERNEL_VERSION(4, 14, 0);``
-
-	``printf ("Version: %u.%u.%u\\n",``
-
-	``(version >> 16) & 0xFF, (version >> 8) & 0xFF, version & 0xFF);``
-    * - __u32
-      - ``capabilities``
-      - Available capabilities of the physical device as a whole, see
-	:ref:`device-capabilities`. The same physical device can export
-	multiple devices in /dev (e.g. /dev/videoX, /dev/vbiY and
-	/dev/radioZ). The ``capabilities`` field should contain a union of
-	all capabilities available around the several V4L2 devices
-	exported to userspace. For all those devices the ``capabilities``
-	field returns the same set of capabilities. This allows
-	applications to open just one of the devices (typically the video
-	device) and discover whether video, vbi and/or radio are also
-	supported.
-    * - __u32
-      - ``device_caps``
-      - Device capabilities of the opened device, see
-	:ref:`device-capabilities`. Should contain the available
-	capabilities of that specific device node. So, for example,
-	``device_caps`` of a radio device will only contain radio related
-	capabilities and no video or vbi capabilities. This field is only
-	set if the ``capabilities`` field contains the
-	``V4L2_CAP_DEVICE_CAPS`` capability. Only the ``capabilities``
-	field can have the ``V4L2_CAP_DEVICE_CAPS`` capability,
-	``device_caps`` will never set ``V4L2_CAP_DEVICE_CAPS``.
-    * - __u32
-      - ``reserved``\ [3]
-      - Reserved for future extensions. Drivers must set this array to
-	zero.

-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-.. [#f1]
-   The struct :c:type:`v4l2_framebuffer` lacks an
-   enum :c:type:`v4l2_buf_type` field, therefore the
-   type of overlay is implied by the driver capabilities.

-Description
-===========
-
-To query the attributes of a control applications set the ``id`` field
-of a struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` and call the
-``VIDIOC_QUERYCTRL`` ioctl with a pointer to this structure. The driver
-fills the rest of the structure or returns an ``EINVAL`` error code when the
-``id`` is invalid.
-
-It is possible to enumerate controls by calling ``VIDIOC_QUERYCTRL``
-with successive ``id`` values starting from ``V4L2_CID_BASE`` up to and
-exclusive ``V4L2_CID_LASTP1``. Drivers may return ``EINVAL`` if a control in
-this range is not supported. Further applications can enumerate private
-controls, which are not defined in this specification, by starting at
-``V4L2_CID_PRIVATE_BASE`` and incrementing ``id`` until the driver
-returns ``EINVAL``.
-
-In both cases, when the driver sets the ``V4L2_CTRL_FLAG_DISABLED`` flag
-in the ``flags`` field this control is permanently disabled and should
-be ignored by the application. [#f1]_
-
-When the application ORs ``id`` with ``V4L2_CTRL_FLAG_NEXT_CTRL`` the
-driver returns the next supported non-compound control, or ``EINVAL`` if
-there is none. In addition, the ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` flag
-can be specified to enumerate all compound controls (i.e. controls with
-type ≥ ``V4L2_CTRL_COMPOUND_TYPES`` and/or array control, in other words
-controls that contain more than one value). Specify both
-``V4L2_CTRL_FLAG_NEXT_CTRL`` and ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` in
-order to enumerate all controls, compound or not. Drivers which do not
-support these flags yet always return ``EINVAL``.
-
-The ``VIDIOC_QUERY_EXT_CTRL`` ioctl was introduced in order to better
-support controls that can use compound types, and to expose additional
-control information that cannot be returned in struct
-:ref:`v4l2_queryctrl <v4l2-queryctrl>` since that structure is full.
-
-``VIDIOC_QUERY_EXT_CTRL`` is used in the same way as
-``VIDIOC_QUERYCTRL``, except that the ``reserved`` array must be zeroed
-as well.
-
-Additional information is required for menu controls: the names of the
-menu items. To query them applications set the ``id`` and ``index``
-fields of struct :ref:`v4l2_querymenu <v4l2-querymenu>` and call the
-``VIDIOC_QUERYMENU`` ioctl with a pointer to this structure. The driver
-fills the rest of the structure or returns an ``EINVAL`` error code when the
-``id`` or ``index`` is invalid. Menu items are enumerated by calling
-``VIDIOC_QUERYMENU`` with successive ``index`` values from struct
-:ref:`v4l2_queryctrl <v4l2-queryctrl>` ``minimum`` to ``maximum``,
-inclusive.
-
-.. note::
-
-   It is possible for ``VIDIOC_QUERYMENU`` to return
-   an ``EINVAL`` error code for some indices between ``minimum`` and
-   ``maximum``. In that case that particular menu item is not supported by
-   this driver. Also note that the ``minimum`` value is not necessarily 0.
-
-See also the examples in :ref:`control`.

-	current gain value if the device is in auto-gain mode. In such a
-	case the hardware calculates the gain value based on the lighting
-	conditions which can change over time.
-
-	.. note::
-

-      - 0x0200
-      - The value provided to the control will be propagated to the driver
-	even if it remains constant. This is required when the control

-
-	A typical example would be the ``V4L2_CID_ROTATE`` control.
-

-    An attempt was made to read a write-only control.
-
-.. [#f1]
-   ``V4L2_CTRL_FLAG_DISABLED`` was intended for two purposes: Drivers
-   can skip predefined controls not supported by the hardware (although
-   returning ``EINVAL`` would do as well), or disable predefined and private
-   controls after hardware detection without the trouble of reordering
-   control arrays and indices (``EINVAL`` cannot be used to skip private

-
-Description
-===========
-
-The hardware may be able to detect the current video standard
-automatically. To do so, applications call :ref:`VIDIOC_QUERYSTD` with a
-pointer to a :ref:`v4l2_std_id <v4l2-std-id>` type. The driver
-stores here a set of candidates, this can be a single flag or a set of
-supported standards if for example the hardware can only distinguish
-between 50 and 60 Hz systems. If no signal was detected, then the driver
-will return V4L2_STD_UNKNOWN. When detection is not possible or fails,
-the set must contain all standards supported by the current video input
-or output.
-
-.. note::
-
-   Drivers shall *not* switch the video standard
-   automatically if a new video standard is detected. Instead, drivers
-   should send the ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support
-   this) and expect that userspace will take action by calling
-   :ref:`VIDIOC_QUERYSTD`. The reason is that a new video standard can mean
-   different buffer sizes as well, and you cannot change buffer sizes on
-   the fly. In general, applications that receive the Source Change event
-   will have to call :ref:`VIDIOC_QUERYSTD`, and if the detected video
-   standard is valid they will have to stop streaming, set the new
-   standard, allocate new buffers and start streaming again.
-
-
-Return Value

-
-VIDIOC_REQBUFS - Initiate Memory Mapping, User Pointer I/O or DMA buffer I/O
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_REQBUFS, struct v4l2_requestbuffers *argp )
-    :name: VIDIOC_REQBUFS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_requestbuffers`.
-
-Description
-===========
-
-This ioctl is used to initiate :ref:`memory mapped <mmap>`,
-:ref:`user pointer <userp>` or :ref:`DMABUF <dmabuf>` based I/O.
-Memory mapped buffers are located in device memory and must be allocated
-with this ioctl before they can be mapped into the application's address
-space. User buffers are allocated by applications themselves, and this
-ioctl is merely used to switch the driver into user pointer I/O mode and
-to setup some internal structures. Similarly, DMABUF buffers are
-allocated by applications through a device driver, and this ioctl only
-configures the driver into DMABUF I/O mode without performing any direct
-allocation.
-
-To allocate device buffers applications initialize all fields of the
-struct :c:type:`v4l2_requestbuffers` structure. They set the ``type``
-field to the respective stream or buffer type, the ``count`` field to
-the desired number of buffers, ``memory`` must be set to the requested
-I/O method and the ``reserved`` array must be zeroed. When the ioctl is
-called with a pointer to this structure the driver will attempt to
-allocate the requested number of buffers and it stores the actual number
-allocated in the ``count`` field. It can be smaller than the number
-requested, even zero, when the driver runs out of free memory. A larger
-number is also possible when the driver requires more buffers to
-function correctly. For example video output requires at least two
-buffers, one displayed and one filled by the application.
-
-When the I/O method is not supported the ioctl returns an ``EINVAL`` error
-code.
-
-Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of
-buffers. Note that if any buffers are still mapped or exported via DMABUF,
-then :ref:`VIDIOC_REQBUFS` can only succeed if the
-``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` capability is set. Otherwise
-:ref:`VIDIOC_REQBUFS` will return the ``EBUSY`` error code.
-If ``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` is set, then these buffers are
-orphaned and will be freed when they are unmapped or when the exported DMABUF
-fds are closed. A ``count`` value of zero frees or orphans all buffers, after
-aborting or finishing any DMA in progress, an implicit
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`.

-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_hw_freq_seek`.

-
-Description
-===========
-
-Start a hardware frequency seek from the current frequency. To do this
-applications initialize the ``tuner``, ``type``, ``seek_upward``,
-``wrap_around``, ``spacing``, ``rangelow`` and ``rangehigh`` fields, and
-zero out the ``reserved`` array of a struct
-:c:type:`v4l2_hw_freq_seek` and call the
-``VIDIOC_S_HW_FREQ_SEEK`` ioctl with a pointer to this structure.
-
-The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
-to tell the driver to search a specific band. If the struct
-:c:type:`v4l2_tuner` ``capability`` field has the
-``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag set, these values must fall
-within one of the bands returned by
-:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
-``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag is not set, then these values
-must exactly match those of one of the bands returned by
-:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
-current frequency of the tuner does not fall within the selected band it
-will be clamped to fit in the band before the seek is started.
-
-If an error is returned, then the original frequency will be restored.
-
-This ioctl is supported if the ``V4L2_CAP_HW_FREQ_SEEK`` capability is
-set.
-
-If this ioctl is called from a non-blocking filehandle, then ``EAGAIN``
-error code is returned and no seek takes place.

-    :name: VIDIOC_STREAMON
-
-.. c:function:: int ioctl( int fd, VIDIOC_STREAMOFF, const int *argp )
-    :name: VIDIOC_STREAMOFF
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to an integer.
-
-Description
-===========
-
-The ``VIDIOC_STREAMON`` and ``VIDIOC_STREAMOFF`` ioctl start and stop
-the capture or output process during streaming
-(:ref:`memory mapping <mmap>`, :ref:`user pointer <userp>` or
-:ref:`DMABUF <dmabuf>`) I/O.
-
-Capture hardware is disabled and no input buffers are filled (if there
-are any empty buffers in the incoming queue) until ``VIDIOC_STREAMON``
-has been called. Output hardware is disabled and no video signal is
-produced until ``VIDIOC_STREAMON`` has been called. The ioctl will
-succeed when at least one output buffer is in the incoming queue.
-
-Memory-to-memory devices will not start until ``VIDIOC_STREAMON`` has
-been called for both the capture and output stream types.
-
-If ``VIDIOC_STREAMON`` fails then any already queued buffers will remain
-queued.
-
-The ``VIDIOC_STREAMOFF`` ioctl, apart of aborting or finishing any DMA
-in progress, unlocks any user pointer buffers locked in physical memory,
-and it removes all buffers from the incoming and outgoing queues. That
-means all images captured but not dequeued yet will be lost, likewise
-all images enqueued for output but not transmitted yet. I/O returns to
-the same state as after calling
-:ref:`VIDIOC_REQBUFS` and can be restarted
-accordingly.
-
-If buffers have been queued with :ref:`VIDIOC_QBUF` and
-``VIDIOC_STREAMOFF`` is called without ever having called
-``VIDIOC_STREAMON``, then those queued buffers will also be removed from
-the incoming queue and all are returned to the same state as after
-calling :ref:`VIDIOC_REQBUFS` and can be restarted
-accordingly.
-
-Both ioctls take a pointer to an integer, the desired buffer or stream
-type. This is the same as struct
-:c:type:`v4l2_requestbuffers` ``type``.
-
-If ``VIDIOC_STREAMON`` is called when streaming is already in progress,
-or if ``VIDIOC_STREAMOFF`` is called when streaming is already stopped,
-then 0 is returned. Nothing happens in the case of ``VIDIOC_STREAMON``,
-but ``VIDIOC_STREAMOFF`` will return queued buffers to their starting
-state as mentioned above.
-
-.. note::
-
-   Applications can be preempted for unknown periods right before
-   or after the ``VIDIOC_STREAMON`` or ``VIDIOC_STREAMOFF`` calls, there is
-   no notion of starting or stopping "now". Buffer timestamps can be used
-   to synchronize with other events.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    The buffer ``type`` is not supported, or no buffers have been
-    allocated (memory mapping) or enqueued (output) yet.
-
-EPIPE
-    The driver implements
-    :ref:`pad-level format configuration <pad-level-formats>` and the
-    pipeline configuration is invalid.

-
-
-Description
-===========
-
-This ioctl lets applications enumerate available frame intervals on a
-given sub-device pad. Frame intervals only makes sense for sub-devices
-that can control the frame period on their own. This includes, for
-instance, image sensors and TV tuners.
-
-For the common use case of image sensors, the frame intervals available
-on the sub-device output pad depend on the frame format and size on the
-same pad. Applications must thus specify the desired format and size
-when enumerating frame intervals.
-
-To enumerate frame intervals applications initialize the ``index``,
-``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
-:c:type:`v4l2_subdev_frame_interval_enum`
-and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
-to this structure. Drivers fill the rest of the structure or return an
-EINVAL error code if one of the input fields is invalid. All frame
-intervals are enumerable by beginning at index zero and incrementing by
-one until ``EINVAL`` is returned.
-
-Available frame intervals may depend on the current 'try' formats at
-other pads of the sub-device, as well as on the current active links.
-See :ref:`VIDIOC_SUBDEV_G_FMT` for more
-information about the try formats.
-
-Sub-devices that support the frame interval enumeration ioctl should
-implemented it on a single pad only. Its behaviour when supported on
-multiple pads of the same sub-device is not defined.

-
-
-Description
-===========
-
-This ioctl allows applications to enumerate all frame sizes supported by
-a sub-device on the given pad for the given media bus format. Supported
-formats can be retrieved with the
-:ref:`VIDIOC_SUBDEV_ENUM_MBUS_CODE`
-ioctl.
-
-To enumerate frame sizes applications initialize the ``pad``, ``which``
-, ``code`` and ``index`` fields of the struct
-:c:type:`v4l2_subdev_mbus_code_enum` and
-call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_SIZE` ioctl with a pointer to the
-structure. Drivers fill the minimum and maximum frame sizes or return an
-EINVAL error code if one of the input parameters is invalid.
-
-Sub-devices that only support discrete frame sizes (such as most
-sensors) will return one or more frame sizes with identical minimum and
-maximum values.
-
-Not all possible sizes in given [minimum, maximum] ranges need to be
-supported. For instance, a scaler that uses a fixed-point scaling ratio
-might not be able to produce every frame size between the minimum and
-maximum values. Applications must use the
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl to try the
-sub-device for an exact supported frame size.
-
-Available frame sizes may depend on the current 'try' formats at other

-
-To enumerate media bus formats available at a given sub-device pad
-applications initialize the ``pad``, ``which`` and ``index`` fields of

-error code if either the ``pad`` or ``index`` are invalid. All media bus
-formats are enumerable by beginning at index zero and incrementing by
-one until ``EINVAL`` is returned.

-===========
-
-.. note::
-
-    This is an :ref:`obsolete` interface and may be removed
-    in the future. It is superseded by
-    :ref:`the selection API <VIDIOC_SUBDEV_G_SELECTION>`.
-
-To retrieve the current crop rectangle applications set the ``pad``
-field of a struct :c:type:`v4l2_subdev_crop` to the

-driver fills the members of the ``rect`` field or returns ``EINVAL`` error
-code if the input arguments are invalid, or if cropping is not supported
-on the given pad.
-
-To change the current crop rectangle applications set both the ``pad``
-and ``which`` fields and all members of the ``rect`` field. They then
-call the ``VIDIOC_SUBDEV_S_CROP`` ioctl with a pointer to this
-structure. The driver verifies the requested crop rectangle, adjusts it

-return the struct :c:type:`v4l2_subdev_crop`

-
-Applications can query the device capabilities by setting the ``which``
-to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' crop rectangles are not
-applied to the device by the driver, but are mangled exactly as active
-crop rectangles and stored in the sub-device file handle. Two
-applications querying the same sub-device would thus not interact with
-each other.
-
-Drivers must not return an error solely because the requested crop
-rectangle doesn't match the device capabilities. They must instead
-modify the rectangle to match what the hardware can provide. The

-
-
-Description
-===========
-
-These ioctls are used to negotiate the frame format at specific subdev
-pads in the image pipeline.
-
-To retrieve the current format applications set the ``pad`` field of a
-struct :c:type:`v4l2_subdev_format` to the desired
-pad number as reported by the media API and the ``which`` field to
-``V4L2_SUBDEV_FORMAT_ACTIVE``. When they call the
-``VIDIOC_SUBDEV_G_FMT`` ioctl with a pointer to this structure the
-driver fills the members of the ``format`` field.
-
-To change the current format applications set both the ``pad`` and
-``which`` fields and all members of the ``format`` field. When they call
-the ``VIDIOC_SUBDEV_S_FMT`` ioctl with a pointer to this structure the
-driver verifies the requested format, adjusts it based on the hardware
-capabilities and configures the device. Upon return the struct
-:c:type:`v4l2_subdev_format` contains the current
-format as would be returned by a ``VIDIOC_SUBDEV_G_FMT`` call.
-
-Applications can query the device capabilities by setting the ``which``
-to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' formats are not applied
-to the device by the driver, but are changed exactly as active formats
-and stored in the sub-device file handle. Two applications querying the
-same sub-device would thus not interact with each other.
-
-For instance, to try a format at the output pad of a sub-device,
-applications would first set the try format at the sub-device input with
-the ``VIDIOC_SUBDEV_S_FMT`` ioctl. They would then either retrieve the
-default format at the output pad with the ``VIDIOC_SUBDEV_G_FMT`` ioctl,
-or set the desired output pad format with the ``VIDIOC_SUBDEV_S_FMT``
-ioctl and check the returned value.
-
-Try formats do not depend on active formats, but can depend on the
-current links configuration or sub-device controls value. For instance,
-a low-pass noise filter might crop pixels at the frame boundaries,
-modifying its output frame size.
-
-Drivers must not return an error solely because the requested format
-doesn't match the device capabilities. They must instead modify the
-format to match what the hardware can provide. The modified format
-should be as close as possible to the original request.

-
-Description
-===========
-
-The selections are used to configure various image processing
-functionality performed by the subdevs which affect the image size. This
-currently includes cropping, scaling and composition.
-
-The selection API replaces
-:ref:`the old subdev crop API <VIDIOC_SUBDEV_G_CROP>`. All the
-function of the crop API, and more, are supported by the selections API.
-
-See :ref:`subdev` for more information on how each selection target
-affects the image processing pipeline inside the subdevice.
-
-
-Types of selection targets
---------------------------
-
-There are two types of selection targets: actual and bounds. The actual
-targets are the targets which configure the hardware. The BOUNDS target
-will return a rectangle that contain all possible actual rectangles.
-
-
-Discovering supported features
-------------------------------
-
-To discover which targets are supported, the user can perform
-``VIDIOC_SUBDEV_G_SELECTION`` on them. Any unsupported target will
-return ``EINVAL``.
-
-Selection targets and flags are documented in

-
-EBUSY
-    The selection rectangle can't be changed because the pad is
-    currently busy. This can be caused, for instance, by an active video
-    stream on the pad. The ioctl must not be retried without performing
-    another action to fix the problem first. Only returned by
-    ``VIDIOC_SUBDEV_S_SELECTION``
-
-EINVAL
-    The struct :c:type:`v4l2_subdev_selection`
-    ``pad`` references a non-existing pad, the ``which`` field
-    references a non-existing format, or the selection target is not
-    supported on the given subdev pad.

-Description
-===========
-
-Subscribe or unsubscribe V4L2 event. Subscribed events are dequeued by
-using the :ref:`VIDIOC_DQEVENT` ioctl.

-    * - __u32
-      - ``id``
-      - ID of the event source. If there is no ID associated with the
-	event source, then set this to 0. Whether or not an event needs an
-	ID depends on the event type.
-    * - __u32

-
-    * - ``V4L2_EVENT_SUB_FL_SEND_INITIAL``
-      - 0x0001
-      - When this event is subscribed an initial event will be sent
-	containing the current status. This only makes sense for events
-	that are triggered by a status change such as ``V4L2_EVENT_CTRL``.
-	Other events will ignore this flag.
-    * - ``V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK``
-      - 0x0002
-      - If set, then events directly caused by an ioctl will also be sent
-	to the filehandle that called that ioctl. For example, changing a
-	control using :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` will cause
-	a V4L2_EVENT_CTRL to be sent back to that same filehandle.
-	Normally such events are suppressed to prevent feedback loops
-	where an application changes a control to a one value and then
-	another, and then receives an event telling it that that control
-	has changed to the first value.
-
-	Since it can't tell whether that event was caused by another
-	application or by the :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
-	call it is hard to decide whether to set the control to the value
-	in the event, or ignore it.
-
-	Think carefully when you set this flag so you won't get into
-	situations like that.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-YUV Formats
-***********
-
-YUV is the format native to TV broadcast and composite video signals. It
-separates the brightness information (Y) from the color information (U
-and V or Cb and Cr). The color information consists of red and blue
-*color difference* signals, this way the green component can be
-reconstructed by subtracting from the brightness component. See
-:ref:`colorspaces` for conversion examples. YUV was chosen because
-early television would only transmit brightness information. To add
-color in a way compatible with existing receivers a new signal carrier
-was added to transmit the color difference signals. Secondary in the YUV
-format the U and V components usually have lower resolution than the Y
-component. This is an analog video compression technique taking
-advantage of a property of the human visual system, being more sensitive
-to brightness information.

-The bttv driver
-===============
-
-Release notes for bttv
-----------------------
-
-You'll need at least these config options for bttv:
-
-.. code-block:: none
-
-	CONFIG_I2C=m
-	CONFIG_I2C_ALGOBIT=m
-	CONFIG_VIDEO_DEV=m
-
-The latest bttv version is available from http://bytesex.org/bttv/
-
-
-Make bttv work with your card
------------------------------
-
-Just try "modprobe bttv" and see if that works.
-
-If it doesn't bttv likely could not autodetect your card and needs some
-insmod options.  The most important insmod option for bttv is "card=n"
-to select the correct card type.  If you get video but no sound you've
-very likely specified the wrong (or no) card type.  A list of supported
-cards is in CARDLIST.bttv
-
-If bttv takes very long to load (happens sometimes with the cheap
-cards which have no tuner), try adding this to your modules.conf:
-
-.. code-block:: none
-
-	options i2c-algo-bit bit_test=1
-
-For the WinTV/PVR you need one firmware file from the driver CD:
-hcwamc.rbf.  The file is in the pvr45xxx.exe archive (self-extracting
-zip file, unzip can unpack it).  Put it into the /etc/pvr directory or
-use the firm_altera=<path> insmod option to point the driver to the
-location of the file.
-
-If your card isn't listed in CARDLIST.bttv or if you have trouble making
-audio work, you should read the Sound-FAQ.
-
-
-Autodetecting cards
--------------------
-
-bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
-the Subsystem ID in the second line, looks like this:
-
-.. code-block:: none
-
-	00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
-		Subsystem: Hauppauge computer works Inc. WinTV/GO
-		Flags: bus master, medium devsel, latency 32, IRQ 5
-		Memory at e2000000 (32-bit, prefetchable) [size=4K]
-
-only bt878-based cards can have a subsystem ID (which does not mean
-that every card really has one).  bt848 cards can't have a Subsystem
-ID and therefore can't be autodetected.  There is a list with the ID's
-in bttv-cards.c (in case you are intrested or want to mail patches
-with updates).
-
-
-Still doesn't work?
--------------------
-
-I do NOT have a lab with 30+ different grabber boards and a
-PAL/NTSC/SECAM test signal generator at home, so I often can't
-reproduce your problems.  This makes debugging very difficult for me.
-If you have some knowledge and spare time, please try to fix this
-yourself (patches very welcome of course...)  You know: The linux
-slogan is "Do it yourself".
-
-There is a mailing list at
-http://vger.kernel.org/vger-lists.html#linux-media
-
-If you have trouble with some specific TV card, try to ask there
-instead of mailing me directly.  The chance that someone with the
-same card listens there is much higher...
-
-For problems with sound:  There are a lot of different systems used
-for TV sound all over the world.  And there are also different chips
-which decode the audio signal.  Reports about sound problems ("stereo
-doesn't work") are pretty useless unless you include some details
-about your hardware and the TV sound scheme used in your country (or
-at least the country you are living in).
-
-Modprobe options
-----------------
-
-Note: "modinfo <module>" prints various information about a kernel
-module, among them a complete and up-to-date list of insmod options.
-This list tends to be outdated because it is updated manually ...

-bttv.o
-
-.. code-block:: none
-
-	the bt848/878 (grabber chip) driver
-
-	insmod args:
-		card=n		card type, see CARDLIST for a list.
-		tuner=n		tuner type, see CARDLIST for a list.
-		radio=0/1	card supports radio
-		pll=0/1/2	pll settings
-			0: don't use PLL
-			1: 28 MHz crystal installed
-			2: 35 MHz crystal installed
-
-		triton1=0/1     for Triton1 (+others) compatibility
-		vsfx=0/1	yet another chipset bug compatibility bit
-				see README.quirks for details on these two.
-
-		bigendian=n	Set the endianness of the gfx framebuffer.
-				Default is native endian.
-		fieldnr=0/1	Count fields.  Some TV descrambling software
-				needs this, for others it only generates
-				50 useless IRQs/sec.  default is 0 (off).
-		autoload=0/1	autoload helper modules (tuner, audio).
-				default is 1 (on).
-		bttv_verbose=0/1/2  verbose level (at insmod time, while
-				looking at the hardware).  default is 1.
-		bttv_debug=0/1	debug messages (for capture).
-				default is 0 (off).
-		irq_debug=0/1	irq handler debug messages.
-				default is 0 (off).
-		gbuffers=2-32	number of capture buffers for mmap'ed capture.
-				default is 4.
-		gbufsize=	size of capture buffers. default and
-				maximum value is 0x208000 (~2MB)
-		no_overlay=0	Enable overlay on broken hardware.  There
-				are some chipsets (SIS for example) which
-				are known to have problems with the PCI DMA
-				push used by bttv.  bttv will disable overlay
-				by default on this hardware to avoid crashes.
-				With this insmod option you can override this.
-		no_overlay=1	Disable overlay. It should be used by broken
-				hardware that doesn't support PCI2PCI direct
-				transfers.
-		automute=0/1	Automatically mutes the sound if there is
-				no TV signal, on by default.  You might try
-				to disable this if you have bad input signal
-				quality which leading to unwanted sound
-				dropouts.
-		chroma_agc=0/1	AGC of chroma signal, off by default.
-		adc_crush=0/1	Luminance ADC crush, on by default.
-		i2c_udelay=     Allow reduce I2C speed. Default is 5 usecs
-				(meaning 66,67 Kbps). The default is the
-				maximum supported speed by kernel bitbang
-				algorithm. You may use lower numbers, if I2C
-				messages are lost (16 is known to work on
-				all supported cards).
-
-		bttv_gpio=0/1
-		gpiomask=
-		audioall=
-		audiomux=
-				See Sound-FAQ for a detailed description.
-
-	remap, card, radio and pll accept up to four comma-separated arguments
-	(for multiple boards).
-
-tuner.o
-
-.. code-block:: none
-
-	The tuner driver.  You need this unless you want to use only
-	with a camera or external tuner ...
-
-	insmod args:
-		debug=1		print some debug info to the syslog
-		type=n		type of the tuner chip. n as follows:
-				see CARDLIST for a complete list.
-		pal=[bdgil]	select PAL variant (used for some tuners
-				only, important for the audio carrier).
-
-tvaudio.o
-
-.. code-block:: none
-
-	new, experimental module which is supported to provide a single
-	driver for all simple i2c audio control chips (tda/tea*).
-
-	insmod args:
-		tda8425  = 1	enable/disable the support for the
-		tda9840  = 1	various chips.
-		tda9850  = 1	The tea6300 can't be autodetected and is
-		tda9855  = 1	therefore off by default, if you have
-		tda9873  = 1	this one on your card (STB uses these)
-		tda9874a = 1	you have to enable it explicitly.
-		tea6300  = 0	The two tda985x chips use the same i2c
-		tea6420  = 1	address and can't be disturgished from
-		pic16c54 = 1	each other, you might have to disable
-				the wrong one.
-		debug = 1	print debug messages
-
-	insmod args for tda9874a:
-		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
-					(default is pin 1)
-		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
-					Please read note 3 below!
-		tda9874a_STD=n		select TV sound standard (0..8):
-					0 - A2, B/G
-					1 - A2, M (Korea)
-					2 - A2, D/K (1)
-					3 - A2, D/K (2)
-					4 - A2, D/K (3)
-					5 - NICAM, I
-					6 - NICAM, B/G
-					7 - NICAM, D/K (default)
-					8 - NICAM, L
-
-	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
-	Note 2: tda9874h/a and tda9875 (which is supported separately by
-	tda9875.o) use the same i2c address so both modules should not be
-	used at the same time.
-	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
-		AMSEL=0: auto-mute will switch between NICAM sound
-			 and the sound on 1st carrier (i.e. FM mono or AM).
-		AMSEL=1: auto-mute will switch between NICAM sound
-			 and the analog mono input (MONOIN pin).
-	If tda9874a decoder on your card has MONOIN pin not connected, then
-	use only tda9874_AMSEL=0 or don't specify this option at all.
-	For example:
-	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
-	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
-
-msp3400.o
-
-.. code-block:: none
-
-	The driver for the msp34xx sound processor chips. If you have a
-	stereo card, you probably want to insmod this one.
-
-	insmod args:
-		debug=1/2	print some debug info to the syslog,
-				2 is more verbose.
-		simple=1	Use the "short programming" method.  Newer
-				msp34xx versions support this.  You need this
-				for dbx stereo.  Default is on if supported by
-				the chip.
-		once=1		Don't check the TV-stations Audio mode
-				every few seconds, but only once after
-				channel switches.
-		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
-				should improve things for french people, the
-				carrier autoscan seems to work with FM only...
-
-tea6300.o - OBSOLETE (use tvaudio instead)
-
-.. code-block:: none
-
-	The driver for the tea6300 fader chip.  If you have a stereo
-	card and the msp3400.o doesn't work, you might want to try this
-	one.  This chip is seen on most STB TV/FM cards (usually from
-	Gateway OEM sold surplus on auction sites).
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda8425.o - OBSOLETE (use tvaudio instead)
-
-.. code-block:: none
-
-	The driver for the tda8425 fader chip.  This driver used to be
-	part of bttv.c, so if your sound used to work but does not
-	anymore, try loading this module.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda985x.o - OBSOLETE (use tvaudio instead)
-
-.. code-block:: none
-
-	The driver for the tda9850/55 audio chips.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-		chip=9850/9855	set the chip type.

-
-If the box freezes hard with bttv
----------------------------------
-
-It might be a bttv driver bug.  It also might be bad hardware.  It also
-might be something else ...
-
-Just mailing me "bttv freezes" isn't going to help much.  This README
-has a few hints how you can help to pin down the problem.
-
-
-bttv bugs
-~~~~~~~~~
-
-If some version works and another doesn't it is likely to be a driver
-bug.  It is very helpful if you can tell where exactly it broke
-(i.e. the last working and the first broken version).
-
-With a hard freeze you probably doesn't find anything in the logfiles.
-The only way to capture any kernel messages is to hook up a serial
-console and let some terminal application log the messages.  /me uses
-screen.  See Documentation/admin-guide/serial-console.rst for details on setting
-up a serial console.
-
-Read Documentation/admin-guide/bug-hunting.rst to learn how to get any useful
-information out of a register+stack dump printed by the kernel on
-protection faults (so-called "kernel oops").
-
-If you run into some kind of deadlock, you can try to dump a call trace
-for each process using sysrq-t (see Documentation/admin-guide/sysrq.rst).
-This way it is possible to figure where *exactly* some process in "D"
-state is stuck.
-
-I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
-for some people.  Thus probably a small buglet left somewhere in bttv
-0.7.x.  I have no idea where exactly, it works stable for me and a lot of
-other people.  But in case you have problems with the 0.7.x versions you
-can give 0.8.x a try ...
-
-
-hardware bugs
-~~~~~~~~~~~~~
-
-Some hardware can't deal with PCI-PCI transfers (i.e. grabber => vga).
-Sometimes problems show up with bttv just because of the high load on
-the PCI bus. The bt848/878 chips have a few workarounds for known
-incompatibilities, see README.quirks.
-
-Some folks report that increasing the pci latency helps too,
-althrought I'm not sure whenever this really fixes the problems or
-only makes it less likely to happen.  Both bttv and btaudio have a
-insmod option to set the PCI latency of the device.
-
-Some mainboard have problems to deal correctly with multiple devices
-doing DMA at the same time.  bttv + ide seems to cause this sometimes,
-if this is the case you likely see freezes only with video and hard disk
-access at the same time.  Updating the IDE driver to get the latest and
-greatest workarounds for hardware bugs might fix these problems.
-
-
-other
-~~~~~
-
-If you use some binary-only yunk (like nvidia module) try to reproduce
-the problem without.
-
-IRQ sharing is known to cause problems in some cases.  It works just
-fine in theory and many configurations.  Neverless it might be worth a
-try to shuffle around the PCI cards to give bttv another IRQ or make
-it share the IRQ with some other piece of hardware.  IRQ sharing with
-VGA cards seems to cause trouble sometimes.  I've also seen funny
-effects with bttv sharing the IRQ with the ACPI bridge (and
-apci-enabled kernel).
-
-Bttv quirks
------------
-
-Below is what the bt878 data book says about the PCI bug compatibility
-modes of the bt878 chip.
-
-The triton1 insmod option sets the EN_TBFX bit in the control register.
-The vsfx insmod option does the same for EN_VSFX bit.  If you have
-stability problems you can try if one of these options makes your box
-work solid.
-
-drivers/pci/quirks.c knows about these issues, this way these bits are
-enabled automagically for known-buggy chipsets (look at the kernel
-messages, bttv tells you).
-
-Normal PCI Mode
-~~~~~~~~~~~~~~~
-
-The PCI REQ signal is the logical-or of the incoming function requests.
-The inter-nal GNT[0:1] signals are gated asynchronously with GNT and
-demultiplexed by the audio request signal. Thus the arbiter defaults to
-the video function at power-up and parks there during no requests for
-bus access. This is desirable since the video will request the bus more
-often. However, the audio will have highest bus access priority. Thus
-the audio will have first access to the bus even when issuing a request
-after the video request but before the PCI external arbiter has granted
-access to the Bt879. Neither function can preempt the other once on the
-bus. The duration to empty the entire video PCI FIFO onto the PCI bus is
-very short compared to the bus access latency the audio PCI FIFO can
-tolerate.
-
-
-430FX Compatibility Mode
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-When using the 430FX PCI, the following rules will ensure
-compatibility:
-
- (1) Deassert REQ at the same time as asserting FRAME.
- (2) Do not reassert REQ to request another bus transaction until after
-     finish-ing the previous transaction.
-
-Since the individual bus masters do not have direct control of REQ, a
-simple logical-or of video and audio requests would violate the rules.
-Thus, both the arbiter and the initiator contain 430FX compatibility
-mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in
-Device Control Register on page 104.
-
-When EN_TBFX is enabled, the arbiter ensures that the two compatibility
-rules are satisfied. Before GNT is asserted by the PCI arbiter, this
-internal arbiter may still logical-or the two requests. However, once
-the GNT is issued, this arbiter must lock in its decision and now route
-only the granted request to the REQ pin. The arbiter decision lock
-happens regardless of the state of FRAME because it does not know when
-FRAME will be asserted (typically - each initiator will assert FRAME on
-the cycle following GNT). When FRAME is asserted, it is the initiator s
-responsibility to remove its request at the same time. It is the
-arbiters responsibility to allow this request to flow through to REQ and
-not allow the other request to hold REQ asserted. The decision lock may
-be removed at the end of the transaction: for example, when the bus is
-idle (FRAME and IRDY). The arbiter decision may then continue
-asynchronously until GNT is again asserted.
-
-
-Interfacing with Non-PCI 2.1 Compliant Core Logic
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-A small percentage of core logic devices may start a bus transaction
-during the same cycle that GNT is de-asserted. This is non PCI 2.1
-compliant. To ensure compatibility when using PCs with these PCI
-controllers, the EN_VSFX bit must be enabled (refer to Device Control
-Register on page 104). When in this mode, the arbiter does not pass GNT
-to the internal functions unless REQ is asserted. This prevents a bus
-transaction from starting the same cycle as GNT is de-asserted. This
-also has the side effect of not being able to take advantage of bus
-parking, thus lowering arbitration performance. The Bt879 drivers must
-query for these non-compliant devices, and set the EN_VSFX bit only if
-required.
-
-bttv and sound mini howto
--------------------------
-
-There are a lot of different bt848/849/878/879 based boards available.
-Making video work often is not a big deal, because this is handled
-completely by the bt8xx chip, which is common on all boards.  But
-sound is handled in slightly different ways on each board.
-
-To handle the grabber boards correctly, there is a array tvcards[] in
-bttv-cards.c, which holds the information required for each board.
-Sound will work only, if the correct entry is used (for video it often
-makes no difference).  The bttv driver prints a line to the kernel
-log, telling which card type is used.  Like this one:
-
-.. code-block:: none
-
-	bttv0: model: BT848(Hauppauge old) [autodetected]
-
-You should verify this is correct.  If it isn't, you have to pass the
-correct board type as insmod argument, "insmod bttv card=2" for
-example.  The file CARDLIST has a list of valid arguments for card.
-If your card isn't listed there, you might check the source code for
-new entries which are not listed yet.  If there isn't one for your
-card, you can check if one of the existing entries does work for you
-(just trial and error...).
-
-Some boards have an extra processor for sound to do stereo decoding
-and other nice features.  The msp34xx chips are used by Hauppauge for
-example.  If your board has one, you might have to load a helper
-module like msp3400.o to make sound work.  If there isn't one for the
-chip used on your board:  Bad luck.  Start writing a new one.  Well,
-you might want to check the video4linux mailing list archive first...
-
-Of course you need a correctly installed soundcard unless you have the
-speakers connected directly to the grabber board.  Hint: check the
-mixer settings too.  ALSA for example has everything muted by default.
-
-
-How sound works in detail
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Still doesn't work?  Looks like some driver hacking is required.
-Below is a do-it-yourself description for you.
-
-The bt8xx chips have 32 general purpose pins, and registers to control
-these pins.  One register is the output enable register
-(BT848_GPIO_OUT_EN), it says which pins are actively driven by the
-bt848 chip.  Another one is the data register (BT848_GPIO_DATA), where
-you can get/set the status if these pins.  They can be used for input
-and output.
-
-Most grabber board vendors use these pins to control an external chip
-which does the sound routing.  But every board is a little different.
-These pins are also used by some companies to drive remote control
-receiver chips.  Some boards use the i2c bus instead of the gpio pins
-to connect the mux chip.
-
-As mentioned above, there is a array which holds the required
-information for each known board.  You basically have to create a new
-line for your board.  The important fields are these two:
-
-.. code-block:: c
-
-	struct tvcard
-	{
-		[ ... ]
-		u32 gpiomask;
-		u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
-	};
-
-gpiomask specifies which pins are used to control the audio mux chip.
-The corresponding bits in the output enable register
-(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the
-bt848 chip.
-
-The audiomux\[\] array holds the data values for the different inputs
-(i.e. which pins must be high/low for tuner/mute/...).  This will be
-written to the data register (BT848_GPIO_DATA) to switch the audio
-mux.
-
-
-What you have to do is figure out the correct values for gpiomask and
-the audiomux array.  If you have Windows and the drivers four your
-card installed, you might to check out if you can read these registers
-values used by the windows driver.  A tool to do this is available
-from ftp://telepresence.dmem.strath.ac.uk/pub/bt848/winutil, but it
-doesn't work with bt878 boards according to some reports I received.
-Another one with bt878 support is available from
-http://btwincap.sourceforge.net/Files/btspy2.00.zip
-
-You might also dig around in the \*.ini files of the Windows applications.
-You can have a look at the board to see which of the gpio pins are
-connected at all and then start trial-and-error ...
-
-
-Starting with release 0.7.41 bttv has a number of insmod options to
-make the gpio debugging easier:
-
-.. code-block:: none
-
-	bttv_gpio=0/1		enable/disable gpio debug messages
-	gpiomask=n		set the gpiomask value
-	audiomux=i,j,...	set the values of the audiomux array
-	audioall=a		set the values of the audiomux array (one
-				value for all array elements, useful to check
-				out which effect the particular value has).
-
-The messages printed with bttv_gpio=1 look like this:
-
-.. code-block:: none
-
-	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
-
-	en  =	output _en_able register (BT848_GPIO_OUT_EN)
-	out =	_out_put bits of the data register (BT848_GPIO_DATA),
-		i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
-	in  = 	_in_put bits of the data register,
-		i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN
-
-
-
-Other elements of the tvcards array
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you are trying to make a new card work you might find it useful to
-know what the other elements in the tvcards array are good for:
-
-.. code-block:: none
-
-	video_inputs    - # of video inputs the card has
-	audio_inputs    - historical cruft, not used any more.
-	tuner           - which input is the tuner
-	svhs            - which input is svhs (all others are labeled composite)
-	muxsel          - video mux, input->registervalue mapping
-	pll             - same as pll= insmod option
-	tuner_type      - same as tuner= insmod option
-	*_modulename    - hint whenever some card needs this or that audio
-			module loaded to work properly.
-	has_radio	- whenever this TV card has a radio tuner.
-	no_msp34xx	- "1" disables loading of msp3400.o module
-	no_tda9875	- "1" disables loading of tda9875.o module
-	needs_tvaudio	- set to "1" to load tvaudio.o module
-
-If some config item is specified both from the tvcards array and as
-insmod option, the insmod option takes precedence.

-This card is basically the same as all the rest (Bt484A, Philips tuner),
-the main difference is that they have attached a programmable attenuator to 3
-GPIO lines in order to give some volume control. They have also stuck an
-infra-red remote control decoded on the board, I will add support for this
-when I get time (it simple generates an interrupt for each key press, with
-the key code is placed in the GPIO port).
-
-I don't yet have any application to test the radio support. The tuner
-frequency setting should work but it is possible that the audio multiplexer
-is wrong. If it doesn't work, send me email.
-
-
-- No Thanks to Leadtek they refused to answer any questions about their
-  hardware. The driver was written by visual inspection of the card. If you
-  use this driver, send an email insult to them, and tell them you won't
-  continue buying their hardware unless they support Linux.
-
-- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw)
-  who make the audio attenuator. Their publicly available data-sheet available
-  on their web site doesn't include the chip programming information! Hidden
-  on their server are the full data-sheets, but don't ask how I found it.
-
-To use the driver I use the following options, the tuner and pll settings might
-be different in your country
-
-insmod videodev
-insmod i2c scan=1 i2c_debug=0 verbose=0
-insmod tuner type=1 debug=0

-The cpia2 driver
-================
-
-Authors: Peter Pregler <Peter_Pregler@email.com>,
-Scott J. Bertin <scottbertin@yahoo.com>, and
-Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
-this one was modelled from.
-
-Introduction
-------------
-
-This is a driver for STMicroelectronics's CPiA2 (second generation
-Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG
-stream at up to vga size. It implements the Video4Linux interface as much as
-possible.  Since the V4L interface does not support compressed formats, only
-an mjpeg enabled application can be used with the camera. We have modified the
-gqcam application to view this stream.
-
-The driver is implemented as two kernel modules. The cpia2 module
-contains the camera functions and the V4L interface.  The cpia2_usb module
-contains usb specific functions.  The main reason for this was the size of the
-module was getting out of hand, so I separated them.  It is not likely that
-there will be a parallel port version.
-
-Features
---------
-
-- Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos
-  sensors. I only have the vga sensor, so can't test the other.
-- Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between.
-  VGA and QVGA are the native image sizes for the VGA camera. CIF is done
-  in the coprocessor by scaling QVGA.  All other sizes are done by clipping.
-- Palette: YCrCb, compressed with MJPEG.
-- Some compression parameters are settable.
-- Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA).
-- Adjust brightness, color, contrast while streaming.
-- Flicker control settable for 50 or 60 Hz mains frequency.
-
-Making and installing the stv672 driver modules
------------------------------------------------
-
-Requirements
-~~~~~~~~~~~~
-
-Video4Linux must be either compiled into the kernel or
-available as a module.  Video4Linux2 is automatically detected and made
-available at compile time.
-
-Setup
-~~~~~
-
-Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
-may be done automatically by your distribution.
-
-Driver options
-~~~~~~~~~~~~~~
-
-.. tabularcolumns:: |p{13ex}|L|
-
-
-==============  ========================================================
-Option		Description
-==============  ========================================================
-video_nr	video device to register (0=/dev/video0, etc)
-		range -1 to 64.  default is -1 (first available)
-		If you have more than 1 camera, this MUST be -1.
-buffer_size	Size for each frame buffer in bytes (default 68k)
-num_buffers	Number of frame buffers (1-32, default 3)
-alternate	USB Alternate (2-7, default 7)
-flicker_freq	Frequency for flicker reduction(50 or 60, default 60)
-flicker_mode	0 to disable, or 1 to enable flicker reduction.
-		(default 0). This is only effective if the camera
-		uses a stv0672 coprocessor.
-==============  ========================================================
-
-Setting the options
-~~~~~~~~~~~~~~~~~~~
-
-If you are using modules, edit /etc/modules.conf and add an options
-line like this:
-
-.. code-block:: none
-
-	options cpia2 num_buffers=3 buffer_size=65535
-
-If the driver is compiled into the kernel, at boot time specify them
-like this:
-
-.. code-block:: none
-
-	cpia2.num_buffers=3 cpia2.buffer_size=65535
-
-What buffer size should I use?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The maximum image size depends on the alternate you choose, and the
-frame rate achieved by the camera.  If the compression engine is able to
-keep up with the frame rate, the maximum image size is given by the table
-below.
-
-The compression engine starts out at maximum compression, and will
-increase image quality until it is close to the size in the table.  As long
-as the compression engine can keep up with the frame rate, after a short time
-the images will all be about the size in the table, regardless of resolution.
-
-At low alternate settings, the compression engine may not be able to
-compress the image enough and will reduce the frame rate by producing larger
-images.
-
-The default of 68k should be good for most users.  This will handle
-any alternate at frame rates down to 15fps.  For lower frame rates, it may
-be necessary to increase the buffer size to avoid having frames dropped due
-to insufficient space.
-

-Table: Image size(bytes)
-
-
-How many buffers should I use?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For normal streaming, 3 should give the best results.  With only 2,
-it is possible for the camera to finish sending one image just after a
-program has started reading the other.  If this happens, the driver must drop
-a frame.  The exception to this is if you have a heavily loaded machine.  In
-this case use 2 buffers.  You are probably not reading at the full frame rate.
-If the camera can send multiple images before a read finishes, it could
-overwrite the third buffer before the read finishes, leading to a corrupt
-image.  Single and double buffering have extra checks to avoid overwriting.
-
-Using the camera
-~~~~~~~~~~~~~~~~
-
-We are providing a modified gqcam application to view the output. In
-order to avoid confusion, here it is called mview.  There is also the qx5view
-program which can also control the lights on the qx5 microscope. MJPEG Tools
-(http://mjpeg.sourceforge.net) can also be used to record from the camera.
-
-Notes to developers
-~~~~~~~~~~~~~~~~~~~
-
-   - This is a driver version stripped of the 2.4 back compatibility
-     and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
-
-Programmer's overview of cpia2 driver
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a
-division of ST Microelectronics).  There are two versions.  The first is the
-STV0672, which is capable of up to 30 frames per second (fps) in frame sizes
-up to CIF, and 15 fps for VGA frames.  The STV0676 is an improved version,
-which can handle up to 30 fps VGA.  Both coprocessors can be attached to two
-CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor.  These will
-be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors.
-
-The two chipsets operate almost identically.  The core is an 8051 processor,
-running two different versions of firmware.  The 672 runs the VP4 video
-processor code, the 676 runs VP5.  There are a few differences in register
-mappings for the two chips.  In these cases, the symbols defined in the
-header files are marked with VP4 or VP5 as part of the symbol name.
-
-The cameras appear externally as three sets of registers. Setting register
-values is the only way to control the camera.  Some settings are
-interdependant, such as the sequence required to power up the camera. I will
-try to make note of all of these cases.
-
-The register sets are called blocks.  Block 0 is the system block.  This
-section is always powered on when the camera is plugged in.  It contains
-registers that control housekeeping functions such as powering up the video
-processor.  The video processor is the VP block.  These registers control
-how the video from the sensor is processed.  Examples are timing registers,
-user mode (vga, qvga), scaling, cropping, framerates, and so on.  The last
-block is the video compressor (VC).  The video stream sent from the camera is
-compressed as Motion JPEG (JPEGA).  The VC controls all of the compression
-parameters.  Looking at the file cpia2_registers.h, you can get a full view
-of these registers and the possible values for most of them.
-
-One or more registers can be set or read by sending a usb control message to
-the camera.  There are three modes for this.  Block mode requests a number
-of contiguous registers.  Random mode reads or writes random registers with
-a tuple structure containing address/value pairs.  The repeat mode is only
-used by VP4 to load a firmware patch.  It contains a starting address and
-a sequence of bytes to be written into a gpio port.

-Memory at cx2341x chips
------------------------
-
-This section describes the cx2341x memory map and documents some of the

-
-.. note:: the memory long words are little-endian ('intel format').
-
-.. warning::
-
-	This information was figured out from searching through the memory
-	and registers, this information may not be correct and is certainly
-	not complete, and was not derived from anything more than searching
-	through the memory space with commands like:
-
-	.. code-block:: none
-
-		ivtvctl -O min=0x02000000,max=0x020000ff
-
-	So take this as is, I'm always searching for more stuff, it's a large
-	register space :-).
-

-This document describes how to upload the cx2341x firmware to the card.
-
-How to find
-~~~~~~~~~~~
-
-See the web pages of the various projects that uses this chip for information
-on how to obtain the firmware.
-
-The firmware stored in a Windows driver can be detected as follows:
-
-- Each firmware image is 256k bytes.
-- The 1st 32-bit word of the Encoder image is 0x0000da7
-- The 1st 32-bit word of the Decoder image is 0x00003a7
-- The 2nd 32-bit word of both images is 0xaa55bb66
-
-How to load
-~~~~~~~~~~~
-
-- Issue the FWapi command to stop the encoder if it is running. Wait for the

-How to call the firmware API
-----------------------------
-
-The preferred calling convention is known as the firmware mailbox. The
-mailboxes are basically a fixed length array that serves as the call-stack.
-
-Firmware mailboxes can be located by searching the encoder and decoder memory
-for a 16 byte signature. That signature will be located on a 256-byte boundary.
-
-Signature:
-
-.. code-block:: none
-
-	0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
-	0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
-
-The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
-reserved for API calls. The second 10 are used by the firmware for event
-notification.
-
-  ====== =================
-  Index  Name
-  ====== =================
-  0      Flags
-  1      Command
-  2      Return value
-  3      Timeout
-  4-19   Parameter/Result
-  ====== =================
-
-
-The flags are defined in the following table. The direction is from the
-perspective of the firmware.
-
-  ==== ========== ============================================
-  Bit  Direction  Purpose
-  ==== ========== ============================================
-  2    O          Firmware has processed the command.
-  1    I          Driver has finished setting the parameters.
-  0    I          Driver is using this mailbox.
-  ==== ========== ============================================
-
-The command is a 32-bit enumerator. The API specifics may be found in this
-chapter.
-
-The return value is a 32-bit enumerator. Only two values are currently defined:
-
-- 0=success
-- -1=command undefined.
-
-There are 16 parameters/results 32-bit fields. The driver populates these fields
-with values for all the parameters required by the call. The driver overwrites
-these fields with result values returned by the call.
-
-The timeout value protects the card from a hung driver thread. If the driver
-doesn't handle the completed call within the timeout specified, the firmware
-will reset that mailbox.
-
-To make an API call, the driver iterates over each mailbox looking for the
-first one available (bit 0 has been cleared). The driver sets that bit, fills
-in the command enumerator, the timeout value and any required parameters. The
-driver then sets the parameter ready bit (bit 1). The firmware scans the
-mailboxes for pending commands, processes them, sets the result code, populates
-the result value array with that call's return values and sets the call
-complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
-and clear all the flags. If the driver does not perform this task within the
-time set in the timeout register, the firmware will reset that mailbox.
-
-Event notifications are sent from the firmware to the host. The host tells the
-firmware which events it is interested in via an API call. That call tells the
-firmware which notification mailbox to use. The firmware signals the host via
-an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
-value and Timeout words are not used.

-This list has been worked out through trial and error. There will be mistakes
-and omissions. Some registers have no obvious effect so it's hard to say what
-they do, while others interact with each other, or require a certain load
-sequence. Horizontal filter setup is one example, with six registers working
-in unison and requiring a certain load sequence to correctly configure. The
-indexed colour palette is much easier to set at just two registers, but again
-it requires a certain load sequence.
-
-Some registers are fussy about what they are set to. Load in a bad value & the
-decoder will fail. A firmware reload will often recover, but sometimes a reset
-is required. For registers containing size information, setting them to 0 is
-generally a bad idea. For other control registers i.e. 2878, you'll only find
-out what values are bad when it hangs.

-	five.
-
-	To correctly program set the filter, this whole procedure must be done 16
-	times. The actual register contents are copied from a lookup-table in the
-	firmware which contains 4 different filter settings.

-
-	To enlarge:
-		Reg 2854 = (source_width * 0x00200000) / destination_width
-		Reg 2874 = No divide
-
-	To reduce from full size down to half size:
-		Reg 2854 = (source_width/2 * 0x00200000) / destination width
-		Reg 2874 = Divide by 2
-
-	To reduce from half size down to quarter size:
-		Reg 2854 = (source_width/4 * 0x00200000) / destination width
-		Reg 2874 = Divide by 4
-
-	The result is always rounded up.

-
-	In normal usage, the first plane is Y & the second plane is UV. Though the

-	Operation is similar to the horizontal Y filter (2804). The only real
-	difference is that there are only two registers to set before accessing

-
-	When the bits-per-pixel is set to 8, the colour mode is ignored and
-	assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
-	is honoured, and when using a colour depth that requires fewer bytes than
-	allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
-	index colour, there are 3 padding bytes per pixel. It's also possible to
-	select 16bpp with a 32 bit colour mode. This results in the pixel width
-	being doubled, but the color key will not work as expected in this mode.
-
-	Colour key is as it suggests. You designate a colour which will become
-	completely transparent. When using 565, 555 or 444 colour modes, the
-	colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
-
-	Local alpha works differently depending on the colour mode. For 32bpp & 8
-	bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
-	transparent and 255 being solid. For the 16bpp modes 555 & 444, the unused
-	bit(s) act as a simple transparency switch, with 0 being solid & 1 being
-	fully transparent. There is no local alpha support for 16bit 565.
-
-	Global alpha is a 256 step transparency that applies to the entire osd,
-	with 0 being transparent & 255 being solid.
-
-	It's possible to combine colour key, local alpha & global alpha.

-The cx231xx DMA engine
-----------------------
-
-
-This page describes the structures and procedures used by the cx2341x DMA
-engine.
-
-Introduction
-~~~~~~~~~~~~
-
-The cx2341x PCI interface is busmaster capable. This means it has a DMA
-engine to efficiently transfer large volumes of data between the card and main
-memory without requiring help from a CPU. Like most hardware, it must operate
-on contiguous physical memory. This is difficult to come by in large quantities
-on virtual memory machines.
-
-Therefore, it also supports a technique called "scatter-gather". The card can
-transfer multiple buffers in one operation. Instead of allocating one large
-contiguous buffer, the driver can allocate several smaller buffers.
-
-In practice, I've seen the average transfer to be roughly 80K, but transfers
-above 128K were not uncommon, particularly at startup. The 128K figure is
-important, because that is the largest block that the kernel can normally
-allocate. Even still, 128K blocks are hard to come by, so the driver writer is
-urged to choose a smaller block size and learn the scatter-gather technique.
-
-Mailbox #10 is reserved for DMA transfer information.
-
-Note: the hardware expects little-endian data ('intel format').
-
-Flow
-~~~~
-
-This section describes, in general, the order of events when handling DMA
-transfers. Detailed information follows this section.
-
-- The card raises the Encoder interrupt.
-- The driver reads the transfer type, offset and size from Mailbox #10.
-- The driver constructs the scatter-gather array from enough free dma buffers
-  to cover the size.
-- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
-- The card raises the DMA Complete interrupt.
-- The driver checks the DMA status register for any errors.
-- The driver post-processes the newly transferred buffers.
-
-NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
-simultaneously. (End of the last, start of the next, etc.)
-
-Mailbox #10
-~~~~~~~~~~~
-
-The Flags, Command, Return Value and Timeout fields are ignored.
-
-- Name:       Mailbox #10
-- Results[0]: Type: 0: MPEG.
-- Results[1]: Offset: The position relative to the card's memory space.
-- Results[2]: Size: The exact number of bytes to transfer.
-
-My speculation is that since the StartCapture API has a capture type of "RAW"
-available, that the type field will have other values that correspond to YUV
-and PCM data.
-
-Scatter-Gather Array
-~~~~~~~~~~~~~~~~~~~~
-
-The scatter-gather array is a contiguously allocated block of memory that
-tells the card the source and destination of each data-block to transfer.
-Card "addresses" are derived from the offset supplied by Mailbox #10. Host
-addresses are the physical memory location of the target DMA buffer.
-
-Each S-G array element is a struct of three 32-bit words. The first word is
-the source address, the second is the destination address. Both take up the
-entire 32 bits. The lowest 18 bits of the third word is the transfer byte
-count. The high-bit of the third word is the "last" flag. The last-flag tells
-the card to raise the DMA_DONE interrupt. From hard personal experience, if
-you forget to set this bit, the card will still "work" but the stream will
-most likely get corrupted.
-
-The transfer count must be a multiple of 256. Therefore, the driver will need
-to track how much data in the target buffer is valid and deal with it
-accordingly.
-
-Array Element:
-
-- 32-bit Source Address
-- 32-bit Destination Address
-- 14-bit reserved (high bit is the last flag)
-- 18-bit byte count
-
-DMA Transfer Status
-~~~~~~~~~~~~~~~~~~~
-
-Register 0x0004 holds the DMA Transfer Status:
-
-- bit 0:   read completed
-- bit 1:   write completed
-- bit 2:   DMA read error
-- bit 3:   DMA write error
-- bit 4:   Scatter-Gather array error
-
-Non-compressed file format
---------------------------
-
-The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
-format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
-for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
-be more accurate.
-
-The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
-four pixels.
-
-The data is encoded as two macroblock planes, the first containing the Y
-values, the second containing UV macroblocks.
-
-The Y plane is divided into blocks of 16x16 pixels from left to right
-and from top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block, the
-second 16 bytes are the second line of the top-left block, etc. After
-transmitting this block the first line of the block on the right to the
-first block is transmitted, etc.
-
-The UV plane is divided into blocks of 16x8 UV values going from left
-to right, top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block and
-contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
-second line of 8 UV pairs of the top-left block, etc. After transmitting
-this block the first line of the block on the right to the first block is
-transmitted, etc.
-
-The code below is given as an example on how to convert HM12 to separate
-Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
-
-The width of a frame is always 720 pixels, regardless of the actual specified
-width.
-
-If the height is not a multiple of 32 lines, then the captured video is
-missing macroblocks at the end and is unusable. So the height must be a
-multiple of 32.

-Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
----------------------------------------------------------
-
-Author: Hans Verkuil <hverkuil@xs4all.nl>
-
-
-This section describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
-embedded in an MPEG-2 program stream. This format is in part dictated by some
-hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
-chips), in particular a maximum size for the VBI data. Anything longer is cut
-off when the MPEG stream is played back through the cx23415.
-
-The advantage of this format is it is very compact and that all VBI data for
-all lines can be stored while still fitting within the maximum allowed size.
-
-The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
-4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
-header and a 42 bytes payload each. Anything beyond this limit is cut off by
-the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
-for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
-signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
-If all lines are used, then there is no longer room for the bitmask. To solve this
-two different magic numbers were introduced:
-
-'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
-unsigned long denote which lines of the first field are captured. Bits 18-31 of
-the first unsigned long and bits 0-3 of the second unsigned long are used for the
-second field.
-
-'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
-implies that the bitmasks are 0xffffffff and 0xf.
-
-After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
-captured VBI lines start:
-
-For each line the least significant 4 bits of the first byte contain the data type.
-Possible values are shown in the table below. The payload is in the following 42
-bytes.
-
-Here is the list of possible data types:
-
-.. code-block:: c
-
-	#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
-	#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
-	#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
-	#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

-The cx88 driver
-===============
-
-Author:  Gerd Hoffmann
-
-This is a v4l2 device driver for the cx2388x chip.
-
-
-Current status
---------------
-
-video
-	- Works.
-	- Overlay isn't supported.
-
-audio
-	- Works. The TV standard detection is made by the driver, as the
-	  hardware has bugs to auto-detect.
-	- audio data dma (i.e. recording without loopback cable to the
-	  sound card) is supported via cx88-alsa.
-
-vbi
-	- Works.
-
-
-How to add support for new cards
---------------------------------
-
-The driver needs some config info for the TV cards.  This stuff is in
-cx88-cards.c.  If the driver doesn't work well you likely need a new
-entry for your card in that file.  Check the kernel log (using dmesg)
-to see whenever the driver knows your card or not.  There is a line
-like this one:
-
-.. code-block:: none
-
-	cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
-		34xxx models [card=1,autodetected]
-
-If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
-the driver.  What to do then?
-
-1) Try upgrading to the latest snapshot, maybe it has been added
-   meanwhile.
-2) You can try to create a new entry yourself, have a look at
-   cx88-cards.c.  If that worked, mail me your changes as unified
-   diff ("diff -u").
-3) Or you can mail me the config information.  We need at least the
-   following information to add the card:
-
-     - the PCI Subsystem ID ("0070:3400" from the line above,
-       "lspci -v" output is fine too).
-     - the tuner type used by the card.  You can try to find one by
-       trial-and-error using the tuner=<n> insmod option.  If you
-       know which one the card has you can also have a look at the
-       list in CARDLIST.tuner
-

-0x47 is the sync byte for MPEG-2 transport stream packets.
-Datasheet incorrectly states to use 47 decimal. 188 is the length.
-All DVB compliant frontends output packets with this start code.

-Hauppauge WinTV cx88 IR information
------------------------------------
-
-The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
-
-====== ======== =================================================
-GPIO0  GPIO1
-====== ======== =================================================
-  0        0    TV Audio
-  1        0    FM radio
-  0        1    Line-In
-  1        1    Mono tuner bypass or CD passthru (tuner specific)
-====== ======== =================================================
-
-GPIO 16(I believe) is tied to the IR port (if present).
-
-
-From the data sheet:
-
-- Register 24'h20004  PCI Interrupt Status
-
- - bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
- - gpio[16] pin into GP_SAMPLE register.
-
-What's missing from the data sheet:
-
-- Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
-  compat remote)
-- set register 0x35C050 to  0xa80a80
-- enable sampling
-- set register 0x35C054 to 0x5
-- enable the IRQ bit 18 in the interrupt mask register (and
-  provide for a handler)
-
-GP_SAMPLE register is at 0x35C058
-
-Bits are then right shifted into the GP_SAMPLE register at the specified
-rate; you get an interrupt when a full DWORD is received.
-You need to recover the actual RC5 bits out of the (oversampled) IR sensor
-bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
-actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
-
-I'm pretty sure when no IR signal is present the receiver is always in a
-marking state(1); but stray light, etc can cause intermittent noise values
-as well.  Remember, this is a free running sample of the IR receiver state
-over time, so don't assume any sample starts at any particular place.

-The VPBE V4L2 driver design

-
-Functional partitioning
------------------------
-
-Consists of the following (in the same order as the list under file
-partitioning):
-
- 1. V4L2 display driver
-    Implements creation of video2 and video3 device nodes and
-    provides v4l2 device interface to manage VID0 and VID1 layers.
-
- 2. Display controller
-    Loads up VENC, OSD and external encoders such as ths8200. It provides
-    a set of API calls to V4L2 drivers to set the output/standards
-    in the VENC or external sub devices. It also provides
-    a device object to access the services from OSD subdevice
-    using sub device ops. The connection of external encoders to VENC LCD
-    controller port is done at init time based on default output and standard
-    selection or at run time when application change the output through
-    V4L2 IOCTLs.
-
-    When connected to an external encoder, vpbe controller is also responsible
-    for setting up the interface between VENC and external encoders based on
-    board specific settings (specified in board-xxx-evm.c). This allows
-    interfacing external encoders such as ths8200. The setup_if_config()
-    is implemented for this as well as configure_venc() (part of the next patch)
-    API to set timings in VENC for a specific display resolution. As of this
-    patch series, the interconnection and enabling and setting of the external
-    encoders is not present, and would be a part of the next patch series.
-
- 3. VENC subdevice module
-    Responsible for setting outputs provided through internal DACs and also
-    setting timings at LCD controller port when external encoders are connected
-    at the port or LCD panel timings required. When external encoder/LCD panel
-    is connected, the timings for a specific standard/preset is retrieved from
-    the board specific table and the values are used to set the timings in
-    venc using non-standard timing mode.
-
-    Support LCD Panel displays using the VENC. For example to support a Logic
-    PD display, it requires setting up the LCD controller port with a set of
-    timings for the resolution supported and setting the dot clock. So we could
-    add the available outputs as a board specific entry (i.e add the "LogicPD"
-    output name to board-xxx-evm.c). A table of timings for various LCDs
-    supported can be maintained in the board specific setup file to support
-    various LCD displays.As of this patch a basic driver is present, and this
-    support for external encoders and displays forms a part of the next
-    patch series.
-
- 4. OSD module
-    OSD module implements all OSD layer management and hardware specific
-    features. The VPBE module interacts with the OSD for enabling and
-    disabling appropriate features of the OSD.
-
-Current status
---------------
-
-A fully functional working version of the V4L2 driver is available. This
-driver has been tested with NTSC and PAL standards and buffer streaming.
-
-To be done
-----------
-
-vpbe display controller
-    - Add support for external encoders.
-    - add support for selecting external encoder as default at probe time.
-
-vpbe venc sub device
-    - add timings for supporting ths8200
-    - add support for LogicPD LCD.
-
-FB drivers
-    - Add support for fbdev drivers.- Ready and part of subsequent patches.

-The Samsung S5P/EXYNOS4 FIMC driver
-===================================
-
-Copyright |copy| 2012 - 2013 Samsung Electronics Co., Ltd.
-
-The FIMC (Fully Interactive Mobile Camera) device available in Samsung
-SoC Application Processors is an integrated camera host interface, color
-space converter, image resizer and rotator.  It's also capable of capturing
-data from LCD controller (FIMD) through the SoC internal writeback data
-path.  There are multiple FIMC instances in the SoCs (up to 4), having
-slightly different capabilities, like pixel alignment constraints, rotator
-availability, LCD writeback support, etc. The driver is located at
-drivers/media/platform/exynos4-is directory.
-
-Supported SoCs
---------------

-
-User space interfaces
----------------------
-
-Media device interface
-~~~~~~~~~~~~~~~~~~~~~~
-
-The driver supports Media Controller API as defined at :ref:`media_controller`.
-The media device driver name is "SAMSUNG S5P FIMC".
-
-The purpose of this interface is to allow changing assignment of FIMC instances
-to the SoC peripheral camera input at runtime and optionally to control internal
-connections of the MIPI-CSIS device(s) to the FIMC entities.
-
-The media device interface allows to configure the SoC for capturing image
-data from the sensor through more than one FIMC instance (e.g. for simultaneous
-viewfinder and still capture setup).
-Reconfiguration is done by enabling/disabling media links created by the driver
-during initialization. The internal device topology can be easily discovered
-through media entity and links enumeration.
-
-Memory-to-memory video node
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-V4L2 memory-to-memory interface at /dev/video? device node.  This is standalone
-video device, it has no media pads. However please note the mem-to-mem and
-capture video node operation on same FIMC instance is not allowed.  The driver
-detects such cases but the applications should prevent them to avoid an
-undefined behaviour.
-
-Capture video node
-~~~~~~~~~~~~~~~~~~
-
-The driver supports V4L2 Video Capture Interface as defined at
-:ref:`devices`.
-
-At the capture and mem-to-mem video nodes only the multi-planar API is
-supported. For more details see: :ref:`planar-apis`.
-
-Camera capture subdevs
-~~~~~~~~~~~~~~~~~~~~~~
-
-Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
-node is also created per each available and enabled at the platform level
-MIPI-CSI receiver device (currently up to two).
-
-sysfs
-~~~~~
-
-In order to enable more precise camera pipeline control through the sub-device
-API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
-device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
-
-In typical use case there could be a following capture pipeline configuration:
-sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
-
-When we configure these devices through sub-device API at user space, the
-configuration flow must be from left to right, and the video node is
-configured as last one.
-When we don't use sub-device user space API the whole configuration of all
-devices belonging to the pipeline is done at the video node driver.
-The sysfs entry allows to instruct the capture node driver not to configure
-the sub-devices (format, crop), to avoid resetting the subdevs' configuration
-when the last configuration steps at the video node is performed.
-
-For full sub-device control support (subdevs configured at user space before
-starting streaming):
-
-.. code-block:: none
-
-	# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
-
-For V4L2 video node control only (subdevs configured internally by the host
-driver):
-
-.. code-block:: none
-
-	# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
-
-This is a default option.
-
-5. Device mapping to video and subdev device nodes
---------------------------------------------------
-
-There are associated two video device nodes with each device instance in
-hardware - video capture and mem-to-mem and additionally a subdev node for
-more precise FIMC capture subsystem control. In addition a separate v4l2
-sub-device node is created per each MIPI-CSIS device.
-
-How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which
-device?
-
-You can either grep through the kernel log to find relevant information, i.e.
-
-.. code-block:: none
-
-	# dmesg | grep -i fimc
-
-(note that udev, if present, might still have rearranged the video nodes),
-
-or retrieve the information from /dev/media? with help of the media-ctl tool:
-
-.. code-block:: none
-
-	# media-ctl -p
-
-7. Build
---------
-
-If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
-two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
-optional s5p-csis.ko (MIPI-CSI receiver subdev).

-i.MX Video Capture Driver
-=========================
-
-Introduction
-------------
-
-The Freescale i.MX5/6 contains an Image Processing Unit (IPU), which
-handles the flow of image frames to and from capture devices and
-display devices.
-
-For image capture, the IPU contains the following internal subunits:
-
-- Image DMA Controller (IDMAC)
-- Camera Serial Interface (CSI)
-- Image Converter (IC)
-- Sensor Multi-FIFO Controller (SMFC)
-- Image Rotator (IRT)
-- Video De-Interlacing or Combining Block (VDIC)
-
-The IDMAC is the DMA controller for transfer of image frames to and from
-memory. Various dedicated DMA channels exist for both video capture and
-display paths. During transfer, the IDMAC is also capable of vertical
-image flip, 8x8 block transfer (see IRT description), pixel component
-re-ordering (for example UYVY to YUYV) within the same colorspace, and
-packed <--> planar conversion. The IDMAC can also perform a simple
-de-interlacing by interweaving even and odd lines during transfer
-(without motion compensation which requires the VDIC).
-
-The CSI is the backend capture unit that interfaces directly with
-camera sensors over Parallel, BT.656/1120, and MIPI CSI-2 buses.
-
-The IC handles color-space conversion, resizing (downscaling and
-upscaling), horizontal flip, and 90/270 degree rotation operations.
-
-There are three independent "tasks" within the IC that can carry out
-conversions concurrently: pre-process encoding, pre-process viewfinder,
-and post-processing. Within each task, conversions are split into three
-sections: downsizing section, main section (upsizing, flip, colorspace
-conversion, and graphics plane combining), and rotation section.
-
-The IPU time-shares the IC task operations. The time-slice granularity
-is one burst of eight pixels in the downsizing section, one image line
-in the main processing section, one image frame in the rotation section.
-
-The SMFC is composed of four independent FIFOs that each can transfer
-captured frames from sensors directly to memory concurrently via four
-IDMAC channels.
-
-The IRT carries out 90 and 270 degree image rotation operations. The
-rotation operation is carried out on 8x8 pixel blocks at a time. This
-operation is supported by the IDMAC which handles the 8x8 block transfer
-along with block reordering, in coordination with vertical flip.
-
-The VDIC handles the conversion of interlaced video to progressive, with
-support for different motion compensation modes (low, medium, and high
-motion). The deinterlaced output frames from the VDIC can be sent to the
-IC pre-process viewfinder task for further conversions. The VDIC also
-contains a Combiner that combines two image planes, with alpha blending
-and color keying.
-
-In addition to the IPU internal subunits, there are also two units
-outside the IPU that are also involved in video capture on i.MX:
-
-- MIPI CSI-2 Receiver for camera sensors with the MIPI CSI-2 bus
-  interface. This is a Synopsys DesignWare core.
-- Two video multiplexers for selecting among multiple sensor inputs
-  to send to a CSI.
-
-For more info, refer to the latest versions of the i.MX5/6 reference
-manuals [#f1]_ and [#f2]_.
-
-
-Features
---------
-
-Some of the features of this driver include:
-
-- Many different pipelines can be configured via media controller API,
-  that correspond to the hardware video capture pipelines supported in
-  the i.MX.
-
-- Supports parallel, BT.565, and MIPI CSI-2 interfaces.
-
-- Concurrent independent streams, by configuring pipelines to multiple
-  video capture interfaces using independent entities.
-
-- Scaling, color-space conversion, horizontal and vertical flip, and
-  image rotation via IC task subdevs.
-
-- Many pixel formats supported (RGB, packed and planar YUV, partial
-  planar YUV).
-
-- The VDIC subdev supports motion compensated de-interlacing, with three
-  motion compensation modes: low, medium, and high motion. Pipelines are
-  defined that allow sending frames to the VDIC subdev directly from the
-  CSI. There is also support in the future for sending frames to the
-  VDIC from memory buffers via a output/mem2mem devices.
-
-- Includes a Frame Interval Monitor (FIM) that can correct vertical sync
-  problems with the ADV718x video decoders.
-
-
-Entities
---------
-
-imx6-mipi-csi2
---------------
-
-This is the MIPI CSI-2 receiver entity. It has one sink pad to receive
-the MIPI CSI-2 stream (usually from a MIPI CSI-2 camera sensor). It has
-four source pads, corresponding to the four MIPI CSI-2 demuxed virtual
-channel outputs. Multiple source pads can be enabled to independently
-stream from multiple virtual channels.
-
-This entity actually consists of two sub-blocks. One is the MIPI CSI-2
-core. This is a Synopsys Designware MIPI CSI-2 core. The other sub-block
-is a "CSI-2 to IPU gasket". The gasket acts as a demultiplexer of the
-four virtual channels streams, providing four separate parallel buses
-containing each virtual channel that are routed to CSIs or video
-multiplexers as described below.
-
-On i.MX6 solo/dual-lite, all four virtual channel buses are routed to
-two video multiplexers. Both CSI0 and CSI1 can receive any virtual
-channel, as selected by the video multiplexers.
-
-On i.MX6 Quad, virtual channel 0 is routed to IPU1-CSI0 (after selected
-by a video mux), virtual channels 1 and 2 are hard-wired to IPU1-CSI1
-and IPU2-CSI0, respectively, and virtual channel 3 is routed to
-IPU2-CSI1 (again selected by a video mux).
-
-ipuX_csiY_mux
--------------
-
-These are the video multiplexers. They have two or more sink pads to
-select from either camera sensors with a parallel interface, or from
-MIPI CSI-2 virtual channels from imx6-mipi-csi2 entity. They have a
-single source pad that routes to a CSI (ipuX_csiY entities).
-
-On i.MX6 solo/dual-lite, there are two video mux entities. One sits
-in front of IPU1-CSI0 to select between a parallel sensor and any of
-the four MIPI CSI-2 virtual channels (a total of five sink pads). The
-other mux sits in front of IPU1-CSI1, and again has five sink pads to
-select between a parallel sensor and any of the four MIPI CSI-2 virtual
-channels.
-
-On i.MX6 Quad, there are two video mux entities. One sits in front of
-IPU1-CSI0 to select between a parallel sensor and MIPI CSI-2 virtual
-channel 0 (two sink pads). The other mux sits in front of IPU2-CSI1 to
-select between a parallel sensor and MIPI CSI-2 virtual channel 3 (two
-sink pads).
-
-ipuX_csiY
----------
-
-These are the CSI entities. They have a single sink pad receiving from
-either a video mux or from a MIPI CSI-2 virtual channel as described
-above.
-
-This entity has two source pads. The first source pad can link directly
-to the ipuX_vdic entity or the ipuX_ic_prp entity, using hardware links
-that require no IDMAC memory buffer transfer.
-
-When the direct source pad is routed to the ipuX_ic_prp entity, frames
-from the CSI can be processed by one or both of the IC pre-processing
-tasks.
-
-When the direct source pad is routed to the ipuX_vdic entity, the VDIC
-will carry out motion-compensated de-interlace using "high motion" mode
-(see description of ipuX_vdic entity).
-
-The second source pad sends video frames directly to memory buffers
-via the SMFC and an IDMAC channel, bypassing IC pre-processing. This
-source pad is routed to a capture device node, with a node name of the
-format "ipuX_csiY capture".
-
-Note that since the IDMAC source pad makes use of an IDMAC channel,
-pixel reordering within the same colorspace can be carried out by the
-IDMAC channel. For example, if the CSI sink pad is receiving in UYVY
-order, the capture device linked to the IDMAC source pad can capture
-in YUYV order. Also, if the CSI sink pad is receiving a packed YUV
-format, the capture device can capture a planar YUV format such as
-YUV420.
-
-The IDMAC channel at the IDMAC source pad also supports simple
-interweave without motion compensation, which is activated if the source
-pad's field type is sequential top-bottom or bottom-top, and the
-requested capture interface field type is set to interlaced (t-b, b-t,
-or unqualified interlaced). The capture interface will enforce the same
-field order as the source pad field order (interlaced-bt if source pad
-is seq-bt, interlaced-tb if source pad is seq-tb).
-
-This subdev can generate the following event when enabling the second
-IDMAC source pad:
-
-- V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR
-
-The user application can subscribe to this event from the ipuX_csiY
-subdev node. This event is generated by the Frame Interval Monitor
-(see below for more on the FIM).
-
-Cropping in ipuX_csiY
----------------------
-
-The CSI supports cropping the incoming raw sensor frames. This is
-implemented in the ipuX_csiY entities at the sink pad, using the
-crop selection subdev API.
-
-The CSI also supports fixed divide-by-two downscaling independently in
-width and height. This is implemented in the ipuX_csiY entities at
-the sink pad, using the compose selection subdev API.
-
-The output rectangle at the ipuX_csiY source pad is the same as
-the compose rectangle at the sink pad. So the source pad rectangle
-cannot be negotiated, it must be set using the compose selection
-API at sink pad (if /2 downscale is desired, otherwise source pad
-rectangle is equal to incoming rectangle).
-
-To give an example of crop and /2 downscale, this will crop a
-1280x960 input frame to 640x480, and then /2 downscale in both
-dimensions to 320x240 (assumes ipu1_csi0 is linked to ipu1_csi0_mux):
-
-.. code-block:: none
-
-   media-ctl -V "'ipu1_csi0_mux':2[fmt:UYVY2X8/1280x960]"
-   media-ctl -V "'ipu1_csi0':0[crop:(0,0)/640x480]"
-   media-ctl -V "'ipu1_csi0':0[compose:(0,0)/320x240]"
-
-Frame Skipping in ipuX_csiY
----------------------------
-
-The CSI supports frame rate decimation, via frame skipping. Frame
-rate decimation is specified by setting the frame intervals at
-sink and source pads. The ipuX_csiY entity then applies the best
-frame skip setting to the CSI to achieve the desired frame rate
-at the source pad.
-
-The following example reduces an assumed incoming 60 Hz frame
-rate by half at the IDMAC output source pad:
-
-.. code-block:: none
-
-   media-ctl -V "'ipu1_csi0':0[fmt:UYVY2X8/640x480@1/60]"
-   media-ctl -V "'ipu1_csi0':2[fmt:UYVY2X8/640x480@1/30]"
-
-Frame Interval Monitor in ipuX_csiY
------------------------------------
-
-The adv718x decoders can occasionally send corrupt fields during
-NTSC/PAL signal re-sync (too little or too many video lines). When
-this happens, the IPU triggers a mechanism to re-establish vertical
-sync by adding 1 dummy line every frame, which causes a rolling effect
-from image to image, and can last a long time before a stable image is
-recovered. Or sometimes the mechanism doesn't work at all, causing a
-permanent split image (one frame contains lines from two consecutive
-captured images).
-
-From experiment it was found that during image rolling, the frame
-intervals (elapsed time between two EOF's) drop below the nominal
-value for the current standard, by about one frame time (60 usec),
-and remain at that value until rolling stops.
-
-While the reason for this observation isn't known (the IPU dummy
-line mechanism should show an increase in the intervals by 1 line
-time every frame, not a fixed value), we can use it to detect the
-corrupt fields using a frame interval monitor. If the FIM detects a
-bad frame interval, the ipuX_csiY subdev will send the event
-V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR. Userland can register with
-the FIM event notification on the ipuX_csiY subdev device node.
-Userland can issue a streaming restart when this event is received
-to correct the rolling/split image.
-
-The ipuX_csiY subdev includes custom controls to tweak some dials for
-FIM. If one of these controls is changed during streaming, the FIM will
-be reset and will continue at the new settings.
-
-- V4L2_CID_IMX_FIM_ENABLE
-
-Enable/disable the FIM.
-
-- V4L2_CID_IMX_FIM_NUM
-
-How many frame interval measurements to average before comparing against
-the nominal frame interval reported by the sensor. This can reduce noise
-caused by interrupt latency.
-
-- V4L2_CID_IMX_FIM_TOLERANCE_MIN
-
-If the averaged intervals fall outside nominal by this amount, in
-microseconds, the V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR event is sent.
-
-- V4L2_CID_IMX_FIM_TOLERANCE_MAX
-
-If any intervals are higher than this value, those samples are
-discarded and do not enter into the average. This can be used to
-discard really high interval errors that might be due to interrupt
-latency from high system load.
-
-- V4L2_CID_IMX_FIM_NUM_SKIP
-
-How many frames to skip after a FIM reset or stream restart before
-FIM begins to average intervals.
-
-- V4L2_CID_IMX_FIM_ICAP_CHANNEL
-- V4L2_CID_IMX_FIM_ICAP_EDGE
-
-These controls will configure an input capture channel as the method
-for measuring frame intervals. This is superior to the default method
-of measuring frame intervals via EOF interrupt, since it is not subject
-to uncertainty errors introduced by interrupt latency.
-
-Input capture requires hardware support. A VSYNC signal must be routed
-to one of the i.MX6 input capture channel pads.
-
-V4L2_CID_IMX_FIM_ICAP_CHANNEL configures which i.MX6 input capture
-channel to use. This must be 0 or 1.
-
-V4L2_CID_IMX_FIM_ICAP_EDGE configures which signal edge will trigger
-input capture events. By default the input capture method is disabled
-with a value of IRQ_TYPE_NONE. Set this control to IRQ_TYPE_EDGE_RISING,
-IRQ_TYPE_EDGE_FALLING, or IRQ_TYPE_EDGE_BOTH to enable input capture,
-triggered on the given signal edge(s).
-
-When input capture is disabled, frame intervals will be measured via
-EOF interrupt.
-
-
-ipuX_vdic
----------
-
-The VDIC carries out motion compensated de-interlacing, with three
-motion compensation modes: low, medium, and high motion. The mode is
-specified with the menu control V4L2_CID_DEINTERLACING_MODE. The VDIC
-has two sink pads and a single source pad.
-
-The direct sink pad receives from an ipuX_csiY direct pad. With this
-link the VDIC can only operate in high motion mode.
-
-When the IDMAC sink pad is activated, it receives from an output
-or mem2mem device node. With this pipeline, the VDIC can also operate
-in low and medium modes, because these modes require receiving
-frames from memory buffers. Note that an output or mem2mem device
-is not implemented yet, so this sink pad currently has no links.
-
-The source pad routes to the IC pre-processing entity ipuX_ic_prp.
-
-ipuX_ic_prp
------------
-
-This is the IC pre-processing entity. It acts as a router, routing
-data from its sink pad to one or both of its source pads.
-
-This entity has a single sink pad. The sink pad can receive from the
-ipuX_csiY direct pad, or from ipuX_vdic.
-
-This entity has two source pads. One source pad routes to the
-pre-process encode task entity (ipuX_ic_prpenc), the other to the
-pre-process viewfinder task entity (ipuX_ic_prpvf). Both source pads
-can be activated at the same time if the sink pad is receiving from
-ipuX_csiY. Only the source pad to the pre-process viewfinder task entity
-can be activated if the sink pad is receiving from ipuX_vdic (frames
-from the VDIC can only be processed by the pre-process viewfinder task).
-
-ipuX_ic_prpenc
---------------
-
-This is the IC pre-processing encode entity. It has a single sink
-pad from ipuX_ic_prp, and a single source pad. The source pad is
-routed to a capture device node, with a node name of the format
-"ipuX_ic_prpenc capture".
-
-This entity performs the IC pre-process encode task operations:
-color-space conversion, resizing (downscaling and upscaling),
-horizontal and vertical flip, and 90/270 degree rotation. Flip
-and rotation are provided via standard V4L2 controls.
-
-Like the ipuX_csiY IDMAC source, this entity also supports simple
-de-interlace without motion compensation, and pixel reordering.
-
-ipuX_ic_prpvf
--------------
-
-This is the IC pre-processing viewfinder entity. It has a single sink
-pad from ipuX_ic_prp, and a single source pad. The source pad is routed
-to a capture device node, with a node name of the format
-"ipuX_ic_prpvf capture".
-
-This entity is identical in operation to ipuX_ic_prpenc, with the same
-resizing and CSC operations and flip/rotation controls. It will receive
-and process de-interlaced frames from the ipuX_vdic if ipuX_ic_prp is
-receiving from ipuX_vdic.
-
-Like the ipuX_csiY IDMAC source, this entity supports simple
-interweaving without motion compensation. However, note that if the
-ipuX_vdic is included in the pipeline (ipuX_ic_prp is receiving from
-ipuX_vdic), it's not possible to use interweave in ipuX_ic_prpvf,
-since the ipuX_vdic has already carried out de-interlacing (with
-motion compensation) and therefore the field type output from
-ipuX_vdic can only be none (progressive).
-
-Capture Pipelines
------------------
-
-The following describe the various use-cases supported by the pipelines.
-
-The links shown do not include the backend sensor, video mux, or mipi
-csi-2 receiver links. This depends on the type of sensor interface
-(parallel or mipi csi-2). So these pipelines begin with:
-
-sensor -> ipuX_csiY_mux -> ...
-
-for parallel sensors, or:
-
-sensor -> imx6-mipi-csi2 -> (ipuX_csiY_mux) -> ...
-
-for mipi csi-2 sensors. The imx6-mipi-csi2 receiver may need to route
-to the video mux (ipuX_csiY_mux) before sending to the CSI, depending
-on the mipi csi-2 virtual channel, hence ipuX_csiY_mux is shown in
-parenthesis.
-
-Unprocessed Video Capture:
---------------------------
-
-Send frames directly from sensor to camera device interface node, with
-no conversions, via ipuX_csiY IDMAC source pad:
-
--> ipuX_csiY:2 -> ipuX_csiY capture
-
-IC Direct Conversions:
-----------------------
-
-This pipeline uses the preprocess encode entity to route frames directly
-from the CSI to the IC, to carry out scaling up to 1024x1024 resolution,
-CSC, flipping, and image rotation:
-
--> ipuX_csiY:1 -> 0:ipuX_ic_prp:1 -> 0:ipuX_ic_prpenc:1 -> ipuX_ic_prpenc capture
-
-Motion Compensated De-interlace:
---------------------------------
-
-This pipeline routes frames from the CSI direct pad to the VDIC entity to
-support motion-compensated de-interlacing (high motion mode only),
-scaling up to 1024x1024, CSC, flip, and rotation:
-
--> ipuX_csiY:1 -> 0:ipuX_vdic:2 -> 0:ipuX_ic_prp:2 -> 0:ipuX_ic_prpvf:1 -> ipuX_ic_prpvf capture
-
-
-Usage Notes
------------
-
-To aid in configuration and for backward compatibility with V4L2
-applications that access controls only from video device nodes, the
-capture device interfaces inherit controls from the active entities
-in the current pipeline, so controls can be accessed either directly
-from the subdev or from the active capture device interface. For
-example, the FIM controls are available either from the ipuX_csiY
-subdevs or from the active capture device.
-
-The following are specific usage notes for the Sabre* reference
-boards:
-
-
-SabreLite with OV5642 and OV5640
---------------------------------
-
-This platform requires the OmniVision OV5642 module with a parallel
-camera interface, and the OV5640 module with a MIPI CSI-2
-interface. Both modules are available from Boundary Devices:
-
-- https://boundarydevices.com/product/nit6x_5mp
-- https://boundarydevices.com/product/nit6x_5mp_mipi
-
-Note that if only one camera module is available, the other sensor
-node can be disabled in the device tree.
-
-The OV5642 module is connected to the parallel bus input on the i.MX
-internal video mux to IPU1 CSI0. It's i2c bus connects to i2c bus 2.
-
-The MIPI CSI-2 OV5640 module is connected to the i.MX internal MIPI CSI-2
-receiver, and the four virtual channel outputs from the receiver are
-routed as follows: vc0 to the IPU1 CSI0 mux, vc1 directly to IPU1 CSI1,
-vc2 directly to IPU2 CSI0, and vc3 to the IPU2 CSI1 mux. The OV5640 is
-also connected to i2c bus 2 on the SabreLite, therefore the OV5642 and
-OV5640 must not share the same i2c slave address.
-
-The following basic example configures unprocessed video capture
-pipelines for both sensors. The OV5642 is routed to ipu1_csi0, and
-the OV5640, transmitting on MIPI CSI-2 virtual channel 1 (which is
-imx6-mipi-csi2 pad 2), is routed to ipu1_csi1. Both sensors are
-configured to output 640x480, and the OV5642 outputs YUYV2X8, the
-OV5640 UYVY2X8:
-
-.. code-block:: none
-
-   # Setup links for OV5642
-   media-ctl -l "'ov5642 1-0042':0 -> 'ipu1_csi0_mux':1[1]"
-   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
-   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
-   # Setup links for OV5640
-   media-ctl -l "'ov5640 1-0040':0 -> 'imx6-mipi-csi2':0[1]"
-   media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
-   media-ctl -l "'ipu1_csi1':2 -> 'ipu1_csi1 capture':0[1]"
-   # Configure pads for OV5642 pipeline
-   media-ctl -V "'ov5642 1-0042':0 [fmt:YUYV2X8/640x480 field:none]"
-   media-ctl -V "'ipu1_csi0_mux':2 [fmt:YUYV2X8/640x480 field:none]"
-   media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/640x480 field:none]"
-   # Configure pads for OV5640 pipeline
-   media-ctl -V "'ov5640 1-0040':0 [fmt:UYVY2X8/640x480 field:none]"
-   media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/640x480 field:none]"
-   media-ctl -V "'ipu1_csi1':2 [fmt:AYUV32/640x480 field:none]"
-
-Streaming can then begin independently on the capture device nodes
-"ipu1_csi0 capture" and "ipu1_csi1 capture". The v4l2-ctl tool can
-be used to select any supported YUV pixelformat on the capture device
-nodes, including planar.

-i.MX6Q SabreAuto with ADV7180 decoder
--------------------------------------
-
-On the i.MX6Q SabreAuto, an on-board ADV7180 SD decoder is connected to the
-parallel bus input on the internal video mux to IPU1 CSI0.
-
-The following example configures a pipeline to capture from the ADV7180
-video decoder, assuming NTSC 720x480 input signals, using simple
-interweave (unconverted and without motion compensation). The adv7180
-must output sequential or alternating fields (field type 'seq-bt' for
-NTSC, or 'alternate'):
-
-.. code-block:: none
-
-   # Setup links
-   media-ctl -l "'adv7180 3-0021':0 -> 'ipu1_csi0_mux':1[1]"
-   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
-   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
-   # Configure pads
-   media-ctl -V "'adv7180 3-0021':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
-   media-ctl -V "'ipu1_csi0_mux':2 [fmt:UYVY2X8/720x480]"
-   media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/720x480]"
-   # Configure "ipu1_csi0 capture" interface (assumed at /dev/video4)
-   v4l2-ctl -d4 --set-fmt-video=field=interlaced_bt
-
-Streaming can then begin on /dev/video4. The v4l2-ctl tool can also be
-used to select any supported YUV pixelformat on /dev/video4.
-
-This example configures a pipeline to capture from the ADV7180
-video decoder, assuming PAL 720x576 input signals, with Motion
-Compensated de-interlacing. The adv7180 must output sequential or
-alternating fields (field type 'seq-tb' for PAL, or 'alternate').
-

-   media-ctl -V "'ipu1_csi0':1 [fmt:AYUV32/720x576]"
-   media-ctl -V "'ipu1_vdic':2 [fmt:AYUV32/720x576 field:none]"

-   media-ctl -V "'ipu1_ic_prpvf':1 [fmt:AYUV32/720x576 field:none]"
-   # Configure "ipu1_ic_prpvf capture" interface (assumed at /dev/video2)
-   v4l2-ctl -d2 --set-fmt-video=field=none
-
-Streaming can then begin on /dev/video2. The v4l2-ctl tool can also be
-used to select any supported YUV pixelformat on /dev/video2.
-
-This platform accepts Composite Video analog inputs to the ADV7180 on
-Ain1 (connector J42).

-
-SabreSD with MIPI CSI-2 OV5640
-------------------------------
-
-Similarly to SabreLite, the SabreSD supports a parallel interface
-OV5642 module on IPU1 CSI0, and a MIPI CSI-2 OV5640 module. The OV5642
-connects to i2c bus 1 and the OV5640 to i2c bus 2.
-
-The device tree for SabreSD includes OF graphs for both the parallel
-OV5642 and the MIPI CSI-2 OV5640, but as of this writing only the MIPI
-CSI-2 OV5640 has been tested, so the OV5642 node is currently disabled.
-The OV5640 module connects to MIPI connector J5 (sorry I don't have the
-compatible module part number or URL).
-
-The following example configures a direct conversion pipeline to capture
-from the OV5640, transmitting on MIPI CSI-2 virtual channel 1. $sensorfmt
-can be any format supported by the OV5640. $sensordim is the frame
-dimension part of $sensorfmt (minus the mbus pixel code). $outputfmt can
-be any format supported by the ipu1_ic_prpenc entity at its output pad:
-
-.. code-block:: none
-
-   # Setup links
-   media-ctl -l "'ov5640 1-003c':0 -> 'imx6-mipi-csi2':0[1]"
-   media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
-   media-ctl -l "'ipu1_csi1':1 -> 'ipu1_ic_prp':0[1]"
-   media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
-   media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"
-   # Configure pads
-   media-ctl -V "'ov5640 1-003c':0 [fmt:$sensorfmt field:none]"
-   media-ctl -V "'imx6-mipi-csi2':2 [fmt:$sensorfmt field:none]"
-   media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/$sensordim field:none]"
-   media-ctl -V "'ipu1_ic_prp':1 [fmt:AYUV32/$sensordim field:none]"
-   media-ctl -V "'ipu1_ic_prpenc':1 [fmt:$outputfmt field:none]"
-
-Streaming can then begin on "ipu1_ic_prpenc capture" node. The v4l2-ctl
-tool can be used to select any supported YUV or RGB pixelformat on the
-capture device node.
-
-
-Known Issues
-------------
-
-1. When using 90 or 270 degree rotation control at capture resolutions
-   near the IC resizer limit of 1024x1024, and combined with planar
-   pixel formats (YUV420, YUV422p), frame capture will often fail with
-   no end-of-frame interrupts from the IDMAC channel. To work around
-   this, use lower resolution and/or packed formats (YUYV, RGB3, etc.)
-   when 90 or 270 rotations are needed.

-Intel Image Processing Unit 3 (IPU3) Imaging Unit (ImgU) driver
-===============================================================

-
-Introduction
-============
-
-This file documents the Intel IPU3 (3rd generation Image Processing Unit)
-Imaging Unit drivers located under drivers/media/pci/intel/ipu3 (CIO2) as well
-as under drivers/staging/media/ipu3 (ImgU).
-
-The Intel IPU3 found in certain Kaby Lake (as well as certain Sky Lake)
-platforms (U/Y processor lines) is made up of two parts namely the Imaging Unit
-(ImgU) and the CIO2 device (MIPI CSI2 receiver).
-
-The CIO2 device receives the raw Bayer data from the sensors and outputs the
-frames in a format that is specific to the IPU3 (for consumption by the IPU3
-ImgU). The CIO2 driver is available as drivers/media/pci/intel/ipu3/ipu3-cio2*
-and is enabled through the CONFIG_VIDEO_IPU3_CIO2 config option.
-
-The Imaging Unit (ImgU) is responsible for processing images captured
-by the IPU3 CIO2 device. The ImgU driver sources can be found under
-drivers/staging/media/ipu3 directory. The driver is enabled through the
-CONFIG_VIDEO_IPU3_IMGU config option.
-
-The two driver modules are named ipu3_csi2 and ipu3_imgu, respectively.
-
-The drivers has been tested on Kaby Lake platforms (U/Y processor lines).
-
-Both of the drivers implement V4L2, Media Controller and V4L2 sub-device
-interfaces. The IPU3 CIO2 driver supports camera sensors connected to the CIO2
-MIPI CSI-2 interfaces through V4L2 sub-device sensor drivers.
-
-CIO2
-====
-
-The CIO2 is represented as a single V4L2 subdev, which provides a V4L2 subdev
-interface to the user space. There is a video node for each CSI-2 receiver,
-with a single media controller interface for the entire device.
-
-The CIO2 contains four independent capture channel, each with its own MIPI CSI-2
-receiver and DMA engine. Each channel is modelled as a V4L2 sub-device exposed
-to userspace as a V4L2 sub-device node and has two pads:
-
-.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
-
-.. flat-table::
-
-    * - pad
-      - direction
-      - purpose
-
-    * - 0
-      - sink
-      - MIPI CSI-2 input, connected to the sensor subdev
-
-    * - 1
-      - source
-      - Raw video capture, connected to the V4L2 video interface
-
-The V4L2 video interfaces model the DMA engines. They are exposed to userspace
-as V4L2 video device nodes.
-
-Capturing frames in raw Bayer format
-------------------------------------
-
-CIO2 MIPI CSI2 receiver is used to capture frames (in packed raw Bayer format)
-from the raw sensors connected to the CSI2 ports. The captured frames are used
-as input to the ImgU driver.
-
-Image processing using IPU3 ImgU requires tools such as raw2pnm [#f1]_, and
-yavta [#f2]_ due to the following unique requirements and / or features specific
-to IPU3.
-
--- The IPU3 CSI2 receiver outputs the captured frames from the sensor in packed
-raw Bayer format that is specific to IPU3.
-
--- Multiple video nodes have to be operated simultaneously.
-
-Let us take the example of ov5670 sensor connected to CSI2 port 0, for a
-2592x1944 image capture.
-
-Using the media contorller APIs, the ov5670 sensor is configured to send
-frames in packed raw Bayer format to IPU3 CSI2 receiver.
-
-# This example assumes /dev/media0 as the CIO2 media device
-
-export MDEV=/dev/media0
-
-# and that ov5670 sensor is connected to i2c bus 10 with address 0x36
-
-export SDEV=$(media-ctl -d $MDEV -e "ov5670 10-0036")
-
-# Establish the link for the media devices using media-ctl [#f3]_
-media-ctl -d $MDEV -l "ov5670:0 -> ipu3-csi2 0:0[1]"
-
-# Set the format for the media devices
-media-ctl -d $MDEV -V "ov5670:0 [fmt:SGRBG10/2592x1944]"
-
-media-ctl -d $MDEV -V "ipu3-csi2 0:0 [fmt:SGRBG10/2592x1944]"
-
-media-ctl -d $MDEV -V "ipu3-csi2 0:1 [fmt:SGRBG10/2592x1944]"
-
-Once the media pipeline is configured, desired sensor specific settings
-(such as exposure and gain settings) can be set, using the yavta tool.
-
-e.g
-
-yavta -w 0x009e0903 444 $SDEV
-
-yavta -w 0x009e0913 1024 $SDEV
-
-yavta -w 0x009e0911 2046 $SDEV
-
-Once the desired sensor settings are set, frame captures can be done as below.
-
-e.g
-
-yavta --data-prefix -u -c10 -n5 -I -s2592x1944 --file=/tmp/frame-#.bin \
-      -f IPU3_SGRBG10 $(media-ctl -d $MDEV -e "ipu3-cio2 0")
-
-With the above command, 10 frames are captured at 2592x1944 resolution, with
-sGRBG10 format and output as IPU3_SGRBG10 format.
-
-The captured frames are available as /tmp/frame-#.bin files.
-
-ImgU
-====
-
-The ImgU is represented as two V4L2 subdevs, each of which provides a V4L2
-subdev interface to the user space.
-
-Each V4L2 subdev represents a pipe, which can support a maximum of 2 streams.
-This helps to support advanced camera features like Continuous View Finder (CVF)
-and Snapshot During Video(SDV).
-
-The ImgU contains two independent pipes, each modelled as a V4L2 sub-device
-exposed to userspace as a V4L2 sub-device node.
-
-Each pipe has two sink pads and three source pads for the following purpose:
-
-.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
-
-.. flat-table::
-
-    * - pad
-      - direction
-      - purpose
-
-    * - 0
-      - sink

-Each pad is connected to a corresponding V4L2 video interface, exposed to 
-userspace as a V4L2 video device node.
-
-Device operation
-----------------
-
-With ImgU, once the input video node ("ipu3-imgu 0/1":0, in
-<entity>:<pad-number> format) is queued with buffer (in packed raw Bayer
-format), ImgU starts processing the buffer and produces the video output in YUV
-format and statistics output on respective output nodes. The driver is expected
-to have buffers ready for all of parameter, output and statistics nodes, when
-input video node is queued with buffer.
-
-At a minimum, all of input, main output, 3A statistics and viewfinder
-video nodes should be enabled for IPU3 to start image processing.
-
-Each ImgU V4L2 subdev has the following set of video nodes.
-
-input, output and viewfinder video nodes
-----------------------------------------
-
-The frames (in packed raw Bayer format specific to the IPU3) received by the
-input video node is processed by the IPU3 Imaging Unit and are output to 2 video
-nodes, with each targeting a different purpose (main output and viewfinder
-output).
-
-Details onand the Bayer format specific to the IPU3 can be found in
-:ref:`v4l2-pix-fmt-ipu3-sbggr10`.
-
-The driver supports V4L2 Video Capture Interface as defined at :ref:`devices`.
-
-Only the multi-planar API is supported. More details can be found at
-:ref:`planar-apis`.
-
-Parameters video node
----------------------
-
-The parameters video node receives the ImgU algorithm parameters that are used
-to configure how the ImgU algorithms process the image.
-
-Details on processing parameters specific to the IPU3 can be found in
-:ref:`v4l2-meta-fmt-params`.
-
-3A statistics video node
-------------------------
-
-3A statistics video node is used by the ImgU driver to output the 3A (auto
-focus, auto exposure and auto white balance) statistics for the frames that are
-being processed by the ImgU to user space applications. User space applications
-can use this statistics data to compute the desired algorithm parameters for
-the ImgU.
-
-Configuring the Intel IPU3
-==========================
-
-The IPU3 ImgU pipelines can be configured using the Media Controller, defined at
-:ref:`media_controller`.
-
-Firmware binary selection
--------------------------
-
-The firmware binary is selected using the V4L2_CID_INTEL_IPU3_MODE, currently
-defined in drivers/staging/media/ipu3/include/intel-ipu3.h . "VIDEO" and "STILL"
-modes are available.
-
-Processing the image in raw Bayer format
-----------------------------------------
-
-Configuring ImgU V4L2 subdev for image processing
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ImgU V4L2 subdevs have to be configured with media controller APIs to have
-all the video nodes setup correctly.
-
-Let us take "ipu3-imgu 0" subdev as an example.
-
-media-ctl -d $MDEV -r
-
-media-ctl -d $MDEV -l "ipu3-imgu 0 input":0 -> "ipu3-imgu 0":0[1]
-
-media-ctl -d $MDEV -l "ipu3-imgu 0":2 -> "ipu3-imgu 0 output":0[1]
-
-media-ctl -d $MDEV -l "ipu3-imgu 0":3 -> "ipu3-imgu 0 viewfinder":0[1]
-
-media-ctl -d $MDEV -l "ipu3-imgu 0":4 -> "ipu3-imgu 0 3a stat":0[1]
-
-Also the pipe mode of the corresponding V4L2 subdev should be set as desired
-(e.g 0 for video mode or 1 for still mode) through the control id 0x009819a1 as
-below.
-
-yavta -w "0x009819A1 1" /dev/v4l-subdev7
-
-Certain hardware blocks in ImgU pipeline can change the frame resolution by
-cropping or scaling, these hardware blocks include Input Feeder(IF), Bayer Down
-Scaler (BDS) and Geometric Distortion Correction (GDC).
-There is also a block which can change the frame resolution - YUV Scaler, it is
-only applicable to the secondary output.
-
-RAW Bayer frames go through these ImgU pipeline hardware blocks and the final
-processed image output to the DDR memory.
-
-.. kernel-figure::  ipu3_rcb.svg
-   :alt: ipu3 resolution blocks image
-
-   IPU3 resolution change hardware blocks
-
-**Input Feeder**
-
-Input Feeder gets the Bayer frame data from the sensor, it can enable cropping
-of lines and columns from the frame and then store pixels into device's internal
-pixel buffer which are ready to readout by following blocks.
-
-**Bayer Down Scaler**
-
-Bayer Down Scaler is capable of performing image scaling in Bayer domain, the
-downscale factor can be configured from 1X to 1/4X in each axis with
-configuration steps of 0.03125 (1/32).
-
-**Geometric Distortion Correction**
-
-Geometric Distortion Correction is used to performe correction of distortions
-and image filtering. It needs some extra filter and envelop padding pixels to
-work, so the input resolution of GDC should be larger than the output
-resolution.
-
-**YUV Scaler**
-
-YUV Scaler which similar with BDS, but it is mainly do image down scaling in
-YUV domain, it can support up to 1/12X down scaling, but it can not be applied
-to the main output.
-
-The ImgU V4L2 subdev has to be configured with the supported resolutions in all
-the above hardware blocks, for a given input resolution.
-For a given supported resolution for an input frame, the Input Feeder, Bayer
-Down Scaler and GDC blocks should be configured with the supported resolutions
-as each hardware block has its own alignment requirement.
-
-You must configure the output resolution of the hardware blocks smartly to meet
-the hardware requirement along with keeping the maximum field of view. The
-intermediate resolutions can be generated by specific tool -
-
-https://github.com/intel/intel-ipu3-pipecfg
-
-This tool can be used to generate intermediate resolutions. More information can
-be obtained by looking at the following IPU3 ImgU configuration table.
-
-https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master
-
-Under baseboard-poppy/media-libs/cros-camera-hal-configs-poppy/files/gcss
-directory, graph_settings_ov5670.xml can be used as an example.
-
-The following steps prepare the ImgU pipeline for the image processing.
-
-1. The ImgU V4L2 subdev data format should be set by using the
-VIDIOC_SUBDEV_S_FMT on pad 0, using the GDC width and height obtained above.
-
-2. The ImgU V4L2 subdev cropping should be set by using the
-VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_CROP as the target,
-using the input feeder height and width.
-
-3. The ImgU V4L2 subdev composing should be set by using the
-VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_COMPOSE as the target,
-using the BDS height and width.
-
-For the ov5670 example, for an input frame with a resolution of 2592x1944
-(which is input to the ImgU subdev pad 0), the corresponding resolutions
-for input feeder, BDS and GDC are 2592x1944, 2592x1944 and 2560x1920
-respectively.
-
-Once this is done, the received raw Bayer frames can be input to the ImgU
-V4L2 subdev as below, using the open source application v4l2n [#f1]_.
-
-For an image captured with 2592x1944 [#f4]_ resolution, with desired output
-resolution as 2560x1920 and viewfinder resolution as 2560x1920, the following
-v4l2n command can be used. This helps process the raw Bayer frames and produces
-the desired results for the main output image and the viewfinder output, in NV12
-format.
-
-v4l2n --pipe=4 --load=/tmp/frame-#.bin --open=/dev/video4
---fmt=type:VIDEO_OUTPUT_MPLANE,width=2592,height=1944,pixelformat=0X47337069
---reqbufs=type:VIDEO_OUTPUT_MPLANE,count:1 --pipe=1 --output=/tmp/frames.out
---open=/dev/video5
---fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
---reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=2 --output=/tmp/frames.vf
---open=/dev/video6
---fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
---reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=3 --open=/dev/video7
---output=/tmp/frames.3A --fmt=type:META_CAPTURE,?
---reqbufs=count:1,type:META_CAPTURE --pipe=1,2,3,4 --stream=5
-
-where /dev/video4, /dev/video5, /dev/video6 and /dev/video7 devices point to
-input, output, viewfinder and 3A statistics video nodes respectively.
-
-Converting the raw Bayer image into YUV domain
-----------------------------------------------
-
-The processed images after the above step, can be converted to YUV domain
-as below.
-
-Main output frames
-~~~~~~~~~~~~~~~~~~
-
-raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.out /tmp/frames.out.ppm
-
-where 2560x1920 is output resolution, NV12 is the video format, followed
-by input frame and output PNM file.
-
-Viewfinder output frames
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.vf /tmp/frames.vf.ppm
-
-where 2560x1920 is output resolution, NV12 is the video format, followed
-by input frame and output PNM file.

-Vaio Picturebook Motion Eye Camera Driver
-=========================================

-
-This driver enable the use of video4linux compatible applications with the
-Motion Eye camera. This driver requires the "Sony Laptop Extras" driver (which
-can be found in the "Misc devices" section of the kernel configuration utility)
-to be compiled and installed (using its "camera=1" parameter).
-
-It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480.
-
-Grabbing is supported in packed YUV colorspace only.
-
-MJPEG hardware grabbing is supported via a private API (see below).
-
-Hardware supported
-------------------
-
-This driver supports the 'second' version of the MotionEye camera :)
-
-The first version was connected directly on the video bus of the Neomagic
-video card and is unsupported.
-
-The second one, made by Kawasaki Steel is fully supported by this
-driver (PCI vendor/device is 0x136b/0xff01)
-
-The third one, present in recent (more or less last year) Picturebooks
-(C1M* models), is not supported. The manufacturer has given the specs
-to the developers under a NDA (which allows the development of a GPL
-driver however), but things are not moving very fast (see
-http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
-
-There is a forth model connected on the USB bus in TR1* Vaio laptops.
-This camera is not supported at all by the current driver, in fact
-little information if any is available for this camera
-(USB vendor/device is 0x054c/0x0107).
-
-Driver options
---------------
-
-Several options can be passed to the meye driver using the standard
-module argument syntax (<param>=<value> when passing the option to the
-module or meye.<param>=<value> on the kernel boot line when meye is
-statically linked into the kernel). Those options are:
-
-.. code-block:: none
-
-	gbuffers:	number of capture buffers, default is 2 (32 max)
-
-	gbufsize:	size of each capture buffer, default is 614400
-
-	video_nr:	video device to register (0 = /dev/video0, etc)
-
-Module use
-----------
-
-In order to automatically load the meye module on use, you can put those lines
-in your /etc/modprobe.d/meye.conf file:
-
-.. code-block:: none
-
-	alias char-major-81 videodev
-	alias char-major-81-0 meye
-	options meye gbuffers=32
-
-Usage:
-------
-
-.. code-block:: none
-
-	xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
-		for display and uncompressed video capture:
-
-			xawtv -c /dev/video0 -geometry 640x480
-				or
-			xawtv -c /dev/video0 -geometry 320x240
-
-	motioneye (<http://popies.net/meye/>)
-		for getting ppm or jpg snapshots, mjpeg video
-
-Private API
------------
-
-The driver supports frame grabbing with the video4linux API,
-so all video4linux tools (like xawtv) should work with this driver.
-
-Besides the video4linux interface, the driver has a private interface
-for accessing the Motion Eye extended parameters (camera sharpness,
-agc, video framerate), the snapshot and the MJPEG capture facilities.
-
-This interface consists of several ioctls (prototypes and structures
-can be found in include/linux/meye.h):
-
-MEYEIOC_G_PARAMS and MEYEIOC_S_PARAMS
-	Get and set the extended parameters of the motion eye camera.
-	The user should always query the current parameters with
-	MEYEIOC_G_PARAMS, change what he likes and then issue the
-	MEYEIOC_S_PARAMS call (checking for -EINVAL). The extended
-	parameters are described by the meye_params structure.
-
-
-MEYEIOC_QBUF_CAPT
-	Queue a buffer for capture (the buffers must have been
-	obtained with a VIDIOCGMBUF call and mmap'ed by the
-	application). The argument to MEYEIOC_QBUF_CAPT is the
-	buffer number to queue (or -1 to end capture). The first
-	call to MEYEIOC_QBUF_CAPT starts the streaming capture.
-
-MEYEIOC_SYNC
-	Takes as an argument the buffer number you want to sync.
-	This ioctl blocks until the buffer is filled and ready
-	for the application to use. It returns the buffer size.
-
-MEYEIOC_STILLCAPT and MEYEIOC_STILLJCAPT
-	Takes a snapshot in an uncompressed or compressed jpeg format.
-	This ioctl blocks until the snapshot is done and returns (for
-	jpeg snapshot) the size of the image. The image data is
-	available from the first mmap'ed buffer.
-
-Look at the 'motioneye' application code for an actual example.
-
-Bugs / Todo
------------
-
-- 'motioneye' still uses the meye private v4l1 API extensions.

-OMAP 3 Image Signal Processor (ISP) driver
-==========================================

-
-Introduction
-------------
-
-This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
-driver located under drivers/media/platform/omap3isp. The original driver was
-written by Texas Instruments but since that it has been rewritten (twice) at
-Nokia.
-
-The driver has been successfully used on the following versions of OMAP 3:
-
-- 3430
-- 3530
-- 3630
-
-The driver implements V4L2, Media controller and v4l2_subdev interfaces.
-Sensor, lens and flash drivers using the v4l2_subdev interface in the kernel
-are supported.
-
-
-Split to subdevs
-----------------
-
-The OMAP 3 ISP is split into V4L2 subdevs, each of the blocks inside the ISP
-having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
-interface to userspace.
-
-- OMAP3 ISP CCP2
-- OMAP3 ISP CSI2a
-- OMAP3 ISP CCDC
-- OMAP3 ISP preview
-- OMAP3 ISP resizer
-- OMAP3 ISP AEWB
-- OMAP3 ISP AF
-- OMAP3 ISP histogram
-
-Each possible link in the ISP is modelled by a link in the Media controller
-interface. For an example program see [#f2]_.
-
-
-Controlling the OMAP 3 ISP
---------------------------
-
-In general, the settings given to the OMAP 3 ISP take effect at the beginning
-of the following frame. This is done when the module becomes idle during the
-vertical blanking period on the sensor. In memory-to-memory operation the pipe
-is run one frame at a time. Applying the settings is done between the frames.
-
-All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver,
-insist on receiving complete frames. Sensors must thus never send the ISP
-partial frames.
-
-Autoidle does have issues with some ISP blocks on the 3430, at least.
-Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle
-is non-zero.
-
-
-Events
-------
-
-The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and
-statistics (AEWB, AF and histogram) subdevs.
-
-The CCDC subdev produces V4L2_EVENT_FRAME_SYNC type event on HS_VS
-interrupt which is used to signal frame start. Earlier version of this
-driver used V4L2_EVENT_OMAP3ISP_HS_VS for this purpose. The event is
-triggered exactly when the reception of the first line of the frame starts
-in the CCDC module. The event can be subscribed on the CCDC subdev.
-
-(When using parallel interface one must pay account to correct configuration
-of the VS signal polarity. This is automatically correct when using the serial
-receivers.)
-
-Each of the statistics subdevs is able to produce events. An event is
-generated whenever a statistics buffer can be dequeued by a user space
-application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available
-are:
-
-- V4L2_EVENT_OMAP3ISP_AEWB
-- V4L2_EVENT_OMAP3ISP_AF
-- V4L2_EVENT_OMAP3ISP_HIST
-
-The type of the event data is struct omap3isp_stat_event_status for these
-ioctls. If there is an error calculating the statistics, there will be an
-event as usual, but no related statistics buffer. In this case
-omap3isp_stat_event_status.buf_err is set to non-zero.
-
-
-Private IOCTLs
---------------
-
-The OMAP 3 ISP driver supports standard V4L2 IOCTLs and controls where
-possible and practical. Much of the functions provided by the ISP, however,
-does not fall under the standard IOCTLs --- gamma tables and configuration of
-statistics collection are examples of such.
-
-In general, there is a private ioctl for configuring each of the blocks
-containing hardware-dependent functions.
-
-The following private IOCTLs are supported:
-
-- VIDIOC_OMAP3ISP_CCDC_CFG
-- VIDIOC_OMAP3ISP_PRV_CFG
-- VIDIOC_OMAP3ISP_AEWB_CFG
-- VIDIOC_OMAP3ISP_HIST_CFG
-- VIDIOC_OMAP3ISP_AF_CFG
-- VIDIOC_OMAP3ISP_STAT_REQ
-- VIDIOC_OMAP3ISP_STAT_EN
-
-The parameter structures used by these ioctls are described in
-include/linux/omap3isp.h. The detailed functions of the ISP itself related to
-a given ISP block is described in the Technical Reference Manuals (TRMs) ---
-see the end of the document for those.
-
-While it is possible to use the ISP driver without any use of these private
-IOCTLs it is not possible to obtain optimal image quality this way. The AEWB,
-AF and histogram modules cannot be used without configuring them using the
-appropriate private IOCTLs.
-
-
-CCDC and preview block IOCTLs
------------------------------
-
-The VIDIOC_OMAP3ISP_CCDC_CFG and VIDIOC_OMAP3ISP_PRV_CFG IOCTLs are used to
-configure, enable and disable functions in the CCDC and preview blocks,
-respectively. Both IOCTLs control several functions in the blocks they
-control. VIDIOC_OMAP3ISP_CCDC_CFG IOCTL accepts a pointer to struct
-omap3isp_ccdc_update_config as its argument. Similarly VIDIOC_OMAP3ISP_PRV_CFG
-accepts a pointer to struct omap3isp_prev_update_config. The definition of
-both structures is available in [#f1]_.
-
-The update field in the structures tells whether to update the configuration
-for the specific function and the flag tells whether to enable or disable the
-function.
-
-The update and flag bit masks accept the following values. Each separate
-functions in the CCDC and preview blocks is associated with a flag (either
-disable or enable; part of the flag field in the structure) and a pointer to
-configuration data for the function.
-
-Valid values for the update and flag fields are listed here for
-VIDIOC_OMAP3ISP_CCDC_CFG. Values may be or'ed to configure more than one
-function in the same IOCTL call.
-
-- OMAP3ISP_CCDC_ALAW
-- OMAP3ISP_CCDC_LPF
-- OMAP3ISP_CCDC_BLCLAMP
-- OMAP3ISP_CCDC_BCOMP
-- OMAP3ISP_CCDC_FPC
-- OMAP3ISP_CCDC_CULL
-- OMAP3ISP_CCDC_CONFIG_LSC
-- OMAP3ISP_CCDC_TBL_LSC
-
-The corresponding values for the VIDIOC_OMAP3ISP_PRV_CFG are here:
-
-- OMAP3ISP_PREV_LUMAENH
-- OMAP3ISP_PREV_INVALAW
-- OMAP3ISP_PREV_HRZ_MED
-- OMAP3ISP_PREV_CFA
-- OMAP3ISP_PREV_CHROMA_SUPP
-- OMAP3ISP_PREV_WB
-- OMAP3ISP_PREV_BLKADJ
-- OMAP3ISP_PREV_RGB2RGB
-- OMAP3ISP_PREV_COLOR_CONV
-- OMAP3ISP_PREV_YC_LIMIT
-- OMAP3ISP_PREV_DEFECT_COR
-- OMAP3ISP_PREV_GAMMABYPASS
-- OMAP3ISP_PREV_DRK_FRM_CAPTURE
-- OMAP3ISP_PREV_DRK_FRM_SUBTRACT
-- OMAP3ISP_PREV_LENS_SHADING
-- OMAP3ISP_PREV_NF
-- OMAP3ISP_PREV_GAMMA
-
-The associated configuration pointer for the function may not be NULL when
-enabling the function. When disabling a function the configuration pointer is
-ignored.
-
-
-Statistic blocks IOCTLs
------------------------
-
-The statistics subdevs do offer more dynamic configuration options than the
-other subdevs. They can be enabled, disable and reconfigured when the pipeline
-is in streaming state.
-
-The statistics blocks always get the input image data from the CCDC (as the
-histogram memory read isn't implemented). The statistics are dequeueable by
-the user from the statistics subdev nodes using private IOCTLs.
-
-The private IOCTLs offered by the AEWB, AF and histogram subdevs are heavily
-reflected by the register level interface offered by the ISP hardware. There
-are aspects that are purely related to the driver implementation and these are
-discussed next.
-
-VIDIOC_OMAP3ISP_STAT_EN
------------------------
-
-This private IOCTL enables/disables a statistic module. If this request is
-done before streaming, it will take effect as soon as the pipeline starts to
-stream.  If the pipeline is already streaming, it will take effect as soon as
-the CCDC becomes idle.
-
-VIDIOC_OMAP3ISP_AEWB_CFG, VIDIOC_OMAP3ISP_HIST_CFG and VIDIOC_OMAP3ISP_AF_CFG
------------------------------------------------------------------------------
-
-Those IOCTLs are used to configure the modules. They require user applications
-to have an in-depth knowledge of the hardware. Most of the fields explanation
-can be found on OMAP's TRMs. The two following fields common to all the above
-configure private IOCTLs require explanation for better understanding as they
-are not part of the TRM.
-
-omap3isp_[h3a_af/h3a_aewb/hist]\_config.buf_size:
-
-The modules handle their buffers internally. The necessary buffer size for the
-module's data output depends on the requested configuration. Although the
-driver supports reconfiguration while streaming, it does not support a
-reconfiguration which requires bigger buffer size than what is already
-internally allocated if the module is enabled. It will return -EBUSY on this
-case. In order to avoid such condition, either disable/reconfigure/enable the
-module or request the necessary buffer size during the first configuration
-while the module is disabled.
-
-The internal buffer size allocation considers the requested configuration's
-minimum buffer size and the value set on buf_size field. If buf_size field is
-out of [minimum, maximum] buffer size range, it's clamped to fit in there.
-The driver then selects the biggest value. The corrected buf_size value is
-written back to user application.
-
-omap3isp_[h3a_af/h3a_aewb/hist]\_config.config_counter:
-
-As the configuration doesn't take effect synchronously to the request, the
-driver must provide a way to track this information to provide more accurate
-data. After a configuration is requested, the config_counter returned to user
-space application will be an unique value associated to that request. When
-user application receives an event for buffer availability or when a new
-buffer is requested, this config_counter is used to match a buffer data and a
-configuration.
-
-VIDIOC_OMAP3ISP_STAT_REQ
-------------------------
-
-Send to user space the oldest data available in the internal buffer queue and
-discards such buffer afterwards. The field omap3isp_stat_data.frame_number
-matches with the video buffer's field_count.
-

-The saa7134 driver
-==================
-
-Author Gerd Hoffmann
-
-
-This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
-boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
-description.
-
-
-Status
-------
-
-Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
-
-As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
-list of known TV cards and saa7134-cards.c for the drivers card
-configuration info.
-
-
-Build
------
-
-Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
-Configure, build, install + boot the new kernel.  You'll need at least
-these config options:
-
-.. code-block:: none
-
-	CONFIG_I2C=m
-	CONFIG_VIDEO_DEV=m
-
-Type "make" to build the driver now.  "make install" installs the
-driver.  "modprobe saa7134" should load it.  Depending on the card you
-might have to pass card=<nr> as insmod option, check CARDLIST for
-valid choices.
-
-
-Changes / Fixes
----------------
-
-Please mail me unified diffs ("diff -u") with your changes, and don't
-forget to tell me what it changes / which problem it fixes / whatever
-it is good for ...
-
-
-Known Problems
---------------
-
-* The tuner for the flyvideos isn't detected automatically and the
-  default might not work for you depending on which version you have.
-  There is a tuner= insmod option to override the driver's default.
-
-Card Variations:
-----------------
-
-Cards can use either of these two crystals (xtal):

-- 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
-
-Some details about 30/34/35:
-
-- saa7130 - low-price chip, doesn't have mute, that is why all those
-  cards should have .mute field defined in their tuner structure.
-
-- saa7134 - usual chip
-
-- saa7133/35 - saa7135 is probably a marketing decision, since all those
-  chips identifies itself as 33 on pci.

-Infrared remote control support in video4linux drivers
-======================================================
-
-Authors: Gerd Hoffmann, Mauro Carvalho Chehab
-
-Basics
-------
-
-Most analog and digital TV boards support remote controllers. Several of
-them have a microprocessor that receives the IR carriers, convert into
-pulse/space sequences and then to scan codes, returning such codes to
-userspace ("scancode mode"). Other boards return just the pulse/space
-sequences ("raw mode").
-
-The support for remote controller in scancode mode is provided by the
-standard Linux input layer. The support for raw mode is provided via LIRC.
-
-In order to check the support and test it, it is suggested to download
-the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_. It provides
-two tools to handle remote controllers:
-
-- ir-keytable: provides a way to query the remote controller, list the
-  protocols it supports, enable in-kernel support for IR decoder or
-  switch the protocol and to test the reception of scan codes;
-
-- ir-ctl: provide tools to handle remote controllers that support raw mode
-  via LIRC interface.
-
-Usually, the remote controller module is auto-loaded when the TV card is
-detected. However, for a few devices, you need to manually load the
-ir-kbd-i2c module.
-
-How it works
-------------
-
-The modules register the remote as keyboard within the linux input
-layer, i.e. you'll see the keys of the remote as normal key strokes
-(if CONFIG_INPUT_KEYBOARD is enabled).
-
-Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
-applications to access the remote via /dev/input/event<n> devices.
-The udev/systemd will automatically create the devices. If you install
-the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_, it may also
-automatically load a different keytable than the default one. Please see
-`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ ir-keytable.1
-man page for details.
-
-The ir-keytable tool is nice for trouble shooting, i.e. to check
-whenever the input device is really present, which of the devices it
-is, check whenever pressing keys on the remote actually generates
-events and the like.  You can also use any other input utility that changes
-the keymaps, like the input kbd utility.
-
-
-Using with lircd
-================
-
-The latest versions of the lircd daemon supports reading events from the
-linux input layer (via event device). It also supports receiving IR codes
-in lirc mode.
-
-
-Using without lircd
-===================
-
-Xorg recognizes several IR keycodes that have its numerical value lower
-than 247. With the advent of Wayland, the input driver got updated too,
-and should now accept all keycodes. Yet, you may want to just reasign
-the keycodes to something that your favorite media application likes.
-
-This can be done by setting
-`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ to load your own
-keytable in runtime. Please read  ir-keytable.1 man page for details.

-The Virtual Media Controller Driver (vimc)
-==========================================
-
-The vimc driver emulates complex video hardware using the V4L2 API and the Media
-API. It has a capture device and three subdevices: sensor, debayer and scaler.
-
-Topology
---------
-
-The topology is hardcoded, although you could modify it in vimc-core and
-recompile the driver to achieve your own topology. This is the default topology:
-
-.. _vimc_topology_graph:
-
-.. kernel-figure:: vimc.dot
-    :alt:   Diagram of the default media pipeline topology
-    :align: center
-
-    Media pipeline graph on vimc
-
-Configuring the topology
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Each subdevice will come with its default configuration (pixelformat, height,
-width, ...). One needs to configure the topology in order to match the
-configuration on each linked subdevice to stream frames through the pipeline.
-If the configuration doesn't match, the stream will fail. The ``v4l-utils``
-package is a bundle of user-space applications, that comes with ``media-ctl`` and
-``v4l2-ctl`` that can be used to configure the vimc configuration. This sequence
-of commands fits for the default topology:
-
-.. code-block:: bash
-
-        media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
-        media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'
-        media-ctl -d platform:vimc -V '"Sensor B":0[fmt:SBGGR8_1X8/640x480]'
-        media-ctl -d platform:vimc -V '"Debayer B":0[fmt:SBGGR8_1X8/640x480]'
-        v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=1920,height=1440
-        v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81
-        v4l2-ctl -z platform:vimc -d "Raw Capture 1" -v pixelformat=BA81
-
-Subdevices
-----------
-
-Subdevices define the behavior of an entity in the topology. Depending on the
-subdevice, the entity can have multiple pads of type source or sink.
-
-vimc-sensor:
-	Generates images in several formats using video test pattern generator.
-	Exposes:
-
-	* 1 Pad source
-
-vimc-debayer:
-	Transforms images in bayer format into a non-bayer format.
-	Exposes:
-
-	* 1 Pad sink
-	* 1 Pad source
-
-vimc-scaler:
-	Scale up the image by a factor of 3. E.g.: a 640x480 image becomes a
-        1920x1440 image. (this value can be configured, see at
-        `Module options`_).
-	Exposes:
-
-	* 1 Pad sink
-	* 1 Pad source
-
-vimc-capture:
-	Exposes node /dev/videoX to allow userspace to capture the stream.
-	Exposes:
-
-	* 1 Pad sink
-	* 1 Pad source
-
-
-Module options
---------------
-
-Vimc has a module parameter to configure the driver.
-
-* ``sca_mult=<unsigned int>``
-
-        Image size multiplier factor to be used to multiply both width and
-        height, so the image size will be ``sca_mult^2`` bigger than the
-        original one. Currently, only supports scaling up (the default value
-        is 3).

-Zoran 364xx based USB webcam module
-===================================
-
-site: http://royale.zerezo.com/zr364xx/
-
-mail: royale@zerezo.com
-
-.. note::
-
-   This documentation is outdated
-
-Introduction
-------------
-
-
-This brings support under Linux for the Aiptek PocketDV 3300 in webcam
-mode. If you just want to get on your PC the pictures and movies on the
-camera, you should use the usb-storage module instead.
-
-The driver works with several other cameras in webcam mode (see the list
-below).
-
-Maybe this code can work for other JPEG/USB cams based on the Coach
-chips from Zoran?
-
-Possible chipsets are : ZR36430 (ZR36430BGC) and
-maybe ZR36431, ZR36440, ZR36442...
-
-You can try the experience changing the vendor/product ID values (look
-at the source code).
-
-You can get these values by looking at /var/log/messages when you plug
-your camera, or by typing : cat /sys/kernel/debug/usb/devices.
-
-If you manage to use your cam with this code, you can send me a mail
-(royale@zerezo.com) with the name of your cam and a patch if needed.
-
-This is a beta release of the driver. Since version 0.70, this driver is
-only compatible with V4L2 API and 2.6.x kernels. If you need V4L1 or
-2.4x kernels support, please use an older version, but the code is not
-maintained anymore. Good luck!
-
-Install
--------
-
-In order to use this driver, you must compile it with your kernel.
-
-Location: Device Drivers -> Multimedia devices -> Video For Linux -> Video Capture Adapters -> V4L USB devices
-
-Usage
------
-
-modprobe zr364xx debug=X mode=Y
-
-- debug      : set to 1 to enable verbose debug messages
-- mode       : 0 = 320x240, 1 = 160x120, 2 = 640x480
-
-You can then use the camera with V4L2 compatible applications, for
-example Ekiga.
-
-To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1M
-count=1

+
+    #include <sys/ioctl.h>
+
+
+.. c:function:: int ioctl( int fd, int request, void *argp )
+   :name: cec-ioctl
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``request``
+    CEC ioctl request code as defined in the cec.h header file, for
+    example :ref:`CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`.
+
+``argp``
+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :c:func:`ioctl() <cec-ioctl>` function manipulates cec device parameters. The
+argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the cec function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying cec ioctl requests and
+their parameters are located in the cec.h header file. All cec ioctl
+requests, their respective function and parameters are specified in
+:ref:`cec-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+
+.. c:function:: int open( const char *device_name, int flags )
+   :name: cec-open
+
+
+Arguments
+=========
+
+``device_name``
+    Device to be opened.
+
+``flags``
+    Open flags. Access mode must be ``O_RDWR``.
+
+    When the ``O_NONBLOCK`` flag is given, the
+    :ref:`CEC_RECEIVE <CEC_RECEIVE>` and :ref:`CEC_DQEVENT <CEC_DQEVENT>` ioctls
+    will return the ``EAGAIN`` error code when no message or event is available, and

+    all return 0.
+
+    Other flags have no effect.
+
+
+Description
+===========
+
+To open a cec device applications call :c:func:`open() <cec-open>` with the
+desired device name. The function has no side effects; the device
+configuration remain unchanged.
+
+When the device is opened in read-only mode, attempts to modify its
+configuration will result in an error, and ``errno`` will be set to
+EBADF.
+
+
+Return Value
+============
+
+:c:func:`open() <cec-open>` returns the new file descriptor on success. On error,
+-1 is returned, and ``errno`` is set appropriately. Possible error codes
+include:
+
+``EACCES``
+    The requested access to the file is not allowed.
+
+``EMFILE``
+    The process already has the maximum number of files open.
+
+``ENFILE``
+    The system limit on the total number of open files has been reached.
+
+``ENOMEM``
+    Insufficient kernel memory was available.
+
+``ENXIO``
+    No device corresponding to this device special file exists.

+cec-poll - Wait for some event on a file descriptor
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
+   :name: cec-poll
+
+Arguments
+=========
+
+``ufds``
+   List of FD events to be watched
+
+``nfds``
+   Number of FD events at the \*ufds array
+
+``timeout``
+   Timeout to wait for events
+
+
+Description
+===========
+
+With the :c:func:`poll() <cec-poll>` function applications can wait for CEC
+events.
+
+On success :c:func:`poll() <cec-poll>` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective struct :c:type:`pollfd`
+is non-zero). CEC devices set the ``POLLIN`` and ``POLLRDNORM`` flags in
+the ``revents`` field if there are messages in the receive queue. If the
+transmit queue has room for new messages, the ``POLLOUT`` and
+``POLLWRNORM`` flags are set. If there are events in the event queue,
+then the ``POLLPRI`` flag is set. When the function times out it returns
+a value of zero, on failure it returns -1 and the ``errno`` variable is
+set appropriately.
+
+For more details see the :c:func:`poll() <cec-poll>` manual page.
+
+
+Return Value
+============
+
+On success, :c:func:`poll() <cec-poll>` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+``EBADF``
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+``EFAULT``
+    ``ufds`` references an inaccessible memory area.
+
+``EINTR``
+    The call was interrupted by a signal.
+
+``EINVAL``
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+Introduction
+============
+
+HDMI connectors provide a single pin for use by the Consumer Electronics
+Control protocol. This protocol allows different devices connected by an
+HDMI cable to communicate. The protocol for CEC version 1.4 is defined
+in supplements 1 (CEC) and 2 (HEAC or HDMI Ethernet and Audio Return
+Channel) of the HDMI 1.4a (:ref:`hdmi`) specification and the
+extensions added to CEC version 2.0 are defined in chapter 11 of the
+HDMI 2.0 (:ref:`hdmi2`) specification.
+
+The bitrate is very slow (effectively no more than 36 bytes per second)
+and is based on the ancient AV.link protocol used in old SCART
+connectors. The protocol closely resembles a crazy Rube Goldberg
+contraption and is an unholy mix of low and high level messages. Some
+messages, especially those part of the HEAC protocol layered on top of
+CEC, need to be handled by the kernel, others can be handled either by
+the kernel or by userspace.
+
+In addition, CEC can be implemented in HDMI receivers, transmitters and
+in USB devices that have an HDMI input and an HDMI output and that
+control just the CEC pin.
+
+Drivers that support CEC will create a CEC device node (/dev/cecX) to
+give userspace access to the CEC adapter. The
+:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
+provides three tools to handle CEC:
+
+- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
+  and monitor CEC messages.
+
+- cec-compliance: does a CEC compliance test of a remote CEC device to
+  determine how compliant the CEC implementation is.
+
+- cec-follower: emulates a CEC follower.

+
+
+Description
+===========
+
+All cec devices must support :ref:`ioctl CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`. To query
+device information, applications call the ioctl with a pointer to a
+struct :c:type:`cec_caps`. The driver fills the structure and
+returns the information to the application. The ioctl never fails.

+      - Userspace can transmit CEC messages by calling
+	:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. This implies that
+	userspace can be a follower as well, since being able to transmit

+
+      - ``CEC_CAP_PASSTHROUGH``
+      - 0x00000008
+      - Userspace can use the passthrough mode by calling

+      - The CEC hardware can monitor CEC pin changes from low to high voltage
+        and vice versa. When in pin monitoring mode the application will
+	receive ``CEC_EVENT_PIN_CEC_LOW`` and ``CEC_EVENT_PIN_CEC_HIGH`` events.
+    * .. _`CEC-CAP-CONNECTOR-INFO`:
+
+      - ``CEC_CAP_CONNECTOR_INFO``
+      - 0x00000100

+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to struct :c:type:`cec_log_addrs`.
+
+Description
+===========
+
+To query the current CEC logical addresses, applications call
+:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
+struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
+
+To set new logical addresses, applications fill in
+struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
+returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
+will be ignored in that case. The adapter will go to the unconfigured state and the
+``cec_version``, ``vendor_id`` and ``osd_name`` fields are all reset to their default
+values (CEC version 2.0, no vendor ID and an empty OSD name).
+
+If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),
+then this ioctl will block until all requested logical
+addresses have been claimed. If the file descriptor is in non-blocking mode then it will
+not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the
+logical addresses are claimed or cleared.
+
+Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when
+logical address types are already defined will return with error ``EBUSY``.

+	``CEC_LOG_ADDR_INVALID``. If this adapter is Unregistered, then
+	``log_addr[0]`` is set to 0xf and all others to
+	``CEC_LOG_ADDR_INVALID``.
+    * - __u16
+      - ``log_addr_mask``
+      - The bitmask of all logical addresses this adapter has claimed. If
+	this adapter is Unregistered then ``log_addr_mask`` sets bit 15
+	and clears all other bits. If this adapter is not configured at
+	all, then ``log_addr_mask`` is set to 0. Set by the driver.
+    * - __u8
+      - ``cec_version``
+      - The CEC version that this adapter shall use. See
+	:ref:`cec-versions`. Used to implement the
+	``CEC_MSG_CEC_VERSION`` and ``CEC_MSG_REPORT_FEATURES`` messages.
+	Note that :ref:`CEC_OP_CEC_VERSION_1_3A <CEC-OP-CEC-VERSION-1-3A>` is not allowed by the CEC
+	framework.
+    * - __u8
+      - ``num_log_addrs``
+      - Number of logical addresses to set up. Must be ≤
+	``available_log_addrs`` as returned by
+	:ref:`CEC_ADAP_G_CAPS`. All arrays in
+	this structure are only filled up to index
+	``available_log_addrs``-1. The remaining array elements will be
+	ignored. Note that the CEC 2.0 standard allows for a maximum of 2
+	logical addresses, although some hardware has support for more.
+	``CEC_MAX_LOG_ADDRS`` is 4. The driver will return the actual
+	number of logical addresses it could claim, which may be less than
+	what was requested. If this field is set to 0, then the CEC
+	adapter shall clear all claimed logical addresses and all other
+	fields will be ignored.
+    * - __u32
+      - ``vendor_id``
+      - The vendor ID is a 24-bit number that identifies the specific
+	vendor or entity. Based on this ID vendor specific commands may be
+	defined. If you do not want a vendor ID then set it to
+	``CEC_VENDOR_ID_NONE``.
+    * - __u32
+      - ``flags``
+      - Flags. See :ref:`cec-log-addrs-flags` for a list of available flags.
+    * - char
+      - ``osd_name[15]``
+      - The On-Screen Display name as is returned by the
+	``CEC_MSG_SET_OSD_NAME`` message.
+    * - __u8
+      - ``primary_device_type[CEC_MAX_LOG_ADDRS]``
+      - Primary device type for each logical address. See
+	:ref:`cec-prim-dev-types` for possible types.
+    * - __u8
+      - ``log_addr_type[CEC_MAX_LOG_ADDRS]``
+      - Logical address types. See :ref:`cec-log-addr-types` for
+	possible types. The driver will update this with the actual
+	logical address type that it claimed (e.g. it may have to fallback
+	to :ref:`CEC_LOG_ADDR_TYPE_UNREGISTERED <CEC-LOG-ADDR-TYPE-UNREGISTERED>`).
+    * - __u8
+      - ``all_device_types[CEC_MAX_LOG_ADDRS]``
+      - CEC 2.0 specific: the bit mask of all device types. See
+	:ref:`cec-all-dev-types-flags`. It is used in the CEC 2.0
+	``CEC_MSG_REPORT_FEATURES`` message. For CEC 1.4 you can either leave
+	this field to 0, or fill it in according to the CEC 2.0 guidelines to
+	give the CEC framework more information about the device type, even
+	though the framework won't use it directly in the CEC message.
+    * - __u8
+      - ``features[CEC_MAX_LOG_ADDRS][12]``
+      - Features for each logical address. It is used in the CEC 2.0
+	``CEC_MSG_REPORT_FEATURES`` message. The 12 bytes include both the
+	RC Profile and the Device Features. For CEC 1.4 you can either leave
+        this field to all 0, or fill it in according to the CEC 2.0 guidelines to
+        give the CEC framework more information about the device type, even
+        though the framework won't use it directly in the CEC message.

+    :name: CEC_ADAP_G_PHYS_ADDR
+
+.. c:function:: int ioctl( int fd, CEC_ADAP_S_PHYS_ADDR, __u16 *argp )
+    :name: CEC_ADAP_S_PHYS_ADDR
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to the CEC address.
+
+Description
+===========
+
+To query the current physical address applications call
+:ref:`ioctl CEC_ADAP_G_PHYS_ADDR <CEC_ADAP_G_PHYS_ADDR>` with a pointer to a __u16 where the
+driver stores the physical address.
+
+To set a new physical address applications store the physical address in
+a __u16 and call :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` with a pointer to
+this integer. The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` is only available if
+``CEC_CAP_PHYS_ADDR`` is set (the ``ENOTTY`` error code will be returned
+otherwise). The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can only be called
+by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
+The adapter will go to the unconfigured state.
+
+If logical address types have been defined (see :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`),
+then this ioctl will block until all
+requested logical addresses have been claimed. If the file descriptor is in non-blocking mode
+then it will not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the physical address
+changes.
+
+The physical address is a 16-bit number where each group of 4 bits
+represent a digit of the physical address a.b.c.d where the most
+significant 4 bits represent 'a'. The CEC root device (usually the TV)
+has address 0.0.0.0. Every device that is hooked up to an input of the
+TV has address a.0.0.0 (where 'a' is ≥ 1), devices hooked up to those in
+turn have addresses a.b.0.0, etc. So a topology of up to 5 devices deep
+is supported. The physical address a device shall use is stored in the
+EDID of the sink.
+
+For example, the EDID for each HDMI input of the TV will have a
+different physical address of the form a.0.0.0 that the sources will
+read out and use as their physical address.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can return the following
+error codes:
+
+ENOTTY
+    The ``CEC_CAP_PHYS_ADDR`` capability wasn't set, so this ioctl is not supported.
+
+EBUSY
+    Another filehandle is in exclusive follower or initiator mode, or the filehandle
+    is in mode ``CEC_MODE_NO_INITIATOR``.
+
+EINVAL
+    The physical address is malformed.

+Synopsis

+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+
+
+Description
+===========
+
+CEC devices can send asynchronous events. These can be retrieved by
+calling :c:func:`CEC_DQEVENT`. If the file descriptor is in
+non-blocking mode and no event is pending, then it will return -1 and
+set errno to the ``EAGAIN`` error code.
+
+The internal event queues are per-filehandle and per-event type. If
+there is no more room in a queue then the last event is overwritten with
+the new one. This means that intermediate results can be thrown away but
+that the latest event is always available. This also means that is it
+possible to read two successive events that have the same value (e.g.
+two :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` events with
+the same state). In that case the intermediate state changes were lost but
+it is guaranteed that the state did change in between the two events.

+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to CEC mode.
+
+Description
+===========
+
+By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
+applications from stepping on each others toes it must be possible to
+obtain exclusive access to the CEC adapter. This ioctl sets the
+filehandle to initiator and/or follower mode which can be exclusive
+depending on the chosen mode. The initiator is the filehandle that is
+used to initiate messages, i.e. it commands other CEC devices. The
+follower is the filehandle that receives messages sent to the CEC
+adapter and processes them. The same filehandle can be both initiator
+and follower, or this role can be taken by two different filehandles.
+
+When a CEC message is received, then the CEC framework will decide how
+it will be processed. If the message is a reply to an earlier
+transmitted message, then the reply is sent back to the filehandle that
+is waiting for it. In addition the CEC framework will process it.
+
+If the message is not a reply, then the CEC framework will process it
+first. If there is no follower, then the message is just discarded and a
+feature abort is sent back to the initiator if the framework couldn't
+process it. If there is a follower, then the message is passed on to the
+follower who will use :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` to dequeue
+the new message. The framework expects the follower to make the right
+decisions.
+
+The CEC framework will process core messages unless requested otherwise
+by the follower. The follower can enable the passthrough mode. In that
+case, the CEC framework will pass on most core messages without
+processing them and the follower will have to implement those messages.
+There are some messages that the core will always process, regardless of
+the passthrough mode. See :ref:`cec-core-processing` for details.
+
+If there is no initiator, then any CEC filehandle can use
+:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If there is an exclusive
+initiator then only that initiator can call
+:ref:`CEC_TRANSMIT`. The follower can of course
+always call :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.

+    :name: CEC_TRANSMIT
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to struct cec_msg.
+
+Description
+===========
+
+To receive a CEC message the application has to fill in the
+``timeout`` field of struct :c:type:`cec_msg` and pass it to
+:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+If the file descriptor is in non-blocking mode and there are no received
+messages pending, then it will return -1 and set errno to the ``EAGAIN``
+error code. If the file descriptor is in blocking mode and ``timeout``
+is non-zero and no message arrived within ``timeout`` milliseconds, then
+it will return -1 and set errno to the ``ETIMEDOUT`` error code.
+
+A received message can be:
+
+1. a message received from another CEC device (the ``sequence`` field will
+   be 0).
+2. the result of an earlier non-blocking transmit (the ``sequence`` field will
+   be non-zero).
+
+To send a CEC message the application has to fill in the struct
+:c:type:`cec_msg` and pass it to :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.
+The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if
+``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit
+queue, then it will return -1 and set errno to the ``EBUSY`` error code.
+The transmit queue has enough room for 18 messages (about 1 second worth
+of 2-byte messages). Note that the CEC kernel framework will also reply
+to core messages (see :ref:`cec-core-processing`), so it is not a good
+idea to fully fill up the transmit queue.
+
+If the file descriptor is in non-blocking mode then the transmit will
+return 0 and the result of the transmit will be available via
+:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` once the transmit has finished
+(including waiting for a reply, if requested).
+
+The ``sequence`` field is filled in for every transmit and this can be
+checked against the received messages to find the corresponding transmit
+result.
+
+Normally calling :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` when the physical
+address is invalid (due to e.g. a disconnect) will return ``ENONET``.
+
+However, the CEC specification allows sending messages from 'Unregistered' to
+'TV' when the physical address is invalid since some TVs pull the hotplug detect
+pin of the HDMI connector low when they go into standby, or when switching to
+another input.
+
+When the hotplug detect pin goes low the EDID disappears, and thus the
+physical address, but the cable is still connected and CEC still works.
+In order to detect/wake up the device it is allowed to send poll and 'Image/Text
+View On' messages from initiator 0xf ('Unregistered') to destination 0 ('TV').

+
+    * - __u64
+      - ``tx_ts``
+      - Timestamp in ns of when the last byte of the message was transmitted.
+	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
+	the same clock from userspace use :c:func:`clock_gettime`.
+    * - __u64
+      - ``rx_ts``
+      - Timestamp in ns of when the last byte of the message was received.
+	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
+	the same clock from userspace use :c:func:`clock_gettime`.
+    * - __u32
+      - ``len``
+      - The length of the message. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in
+	by the application. The driver will fill this in for
+	:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be
+	filled in by the driver with the length of the reply message if ``reply`` was set.
+    * - __u32
+      - ``timeout``
+      - The timeout in milliseconds. This is the time the device will wait
+	for a message to be received before timing out. If it is set to 0,
+	then it will wait indefinitely when it is called by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	If it is 0 and it is called by :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`,
+	then it will be replaced by 1000 if the ``reply`` is non-zero or
+	ignored if ``reply`` is 0.
+    * - __u32
+      - ``sequence``
+      - A non-zero sequence number is automatically assigned by the CEC framework
+	for all transmitted messages. It is used by the CEC framework when it queues
+	the transmit result (when transmit was called in non-blocking mode). This
+	allows the application to associate the received message with the original
+	transmit.
+    * - __u32
+      - ``flags``
+      - Flags. See :ref:`cec-msg-flags` for a list of available flags.
+    * - __u8
+      - ``tx_status``
+      - The status bits of the transmitted message. See
+	:ref:`cec-tx-status` for the possible status values. It is 0 if
+	this message was received, not transmitted.
+    * - __u8
+      - ``msg[16]``
+      - The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
+	application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
+	the payload of the reply message if ``timeout`` was set.
+    * - __u8
+      - ``reply``
+      - Wait until this message is replied. If ``reply`` is 0 and the
+	``timeout`` is 0, then don't wait for a reply but return after
+	transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	The case where ``reply`` is 0 (this is the opcode for the Feature Abort
+	message) and ``timeout`` is non-zero is specifically allowed to make it
+	possible to send a message and wait up to ``timeout`` milliseconds for a
+	Feature Abort reply. In this case ``rx_status`` will either be set
+	to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
+	:ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
+
+	If the transmitter message is ``CEC_MSG_INITIATE_ARC`` then the ``reply``
+	values ``CEC_MSG_REPORT_ARC_INITIATED`` and ``CEC_MSG_REPORT_ARC_TERMINATED``
+	are processed differently: either value will match both possible replies.
+	The reason is that the ``CEC_MSG_INITIATE_ARC`` message is the only CEC
+	message that has two possible replies other than Feature Abort. The
+	``reply`` field will be updated with the actual reply so that it is
+	synchronized with the contents of the received message.
+    * - __u8
+      - ``rx_status``
+      - The status bits of the received message. See
+	:ref:`cec-rx-status` for the possible status values. It is 0 if
+	this message was transmitted, not received, unless this is the
+	reply to a transmitted message. In that case both ``rx_status``
+	and ``tx_status`` are set.
+    * - __u8
+      - ``tx_status``
+      - The status bits of the transmitted message. See
+	:ref:`cec-tx-status` for the possible status values. It is 0 if
+	this message was received, not transmitted.
+    * - __u8
+      - ``tx_arb_lost_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Arbitration Lost error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_ARB_LOST <CEC-TX-STATUS-ARB-LOST>` status bit is set.
+    * - __u8
+      - ``tx_nack_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Not Acknowledged error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_NACK <CEC-TX-STATUS-NACK>` status bit is set.
+    * - __u8
+      - ``tx_low_drive_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Arbitration Lost error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_LOW_DRIVE <CEC-TX-STATUS-LOW-DRIVE>` status bit is set.
+    * - __u8
+      - ``tx_error_cnt``
+      - A counter of the number of transmit errors other than Arbitration
+	Lost or Not Acknowledged. This is only set if the hardware
+	supports this, otherwise it is always 0. This counter is only
+	valid if the :ref:`CEC_TX_STATUS_ERROR <CEC-TX-STATUS-ERROR>` status bit is set.

+	the filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If this
+	flag is set, then the reply is also sent to all followers, if any. If the
+	filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is also a
+	follower, then that filehandle will receive the reply twice: once as the
+	result of the :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`, and once via

+	then no validation takes place and the message is transmitted as-is.
+	This is useful when debugging CEC issues.
+	This flag is only allowed if the process has the ``CAP_SYS_RAWIO``
+	capability. If that is not set, then the ``EPERM`` error code is
+	returned.

+CEC Pin Framework Error Injection
+=================================
+
+The CEC Pin Framework is a core CEC framework for CEC hardware that only
+has low-level support for the CEC bus. Most hardware today will have
+high-level CEC support where the hardware deals with driving the CEC bus,
+but some older devices aren't that fancy. However, this framework also
+allows you to connect the CEC pin to a GPIO on e.g. a Raspberry Pi and
+you have now made a CEC adapter.
+
+What makes doing this so interesting is that since we have full control
+over the bus it is easy to support error injection. This is ideal to
+test how well CEC adapters can handle error conditions.
+
+Currently only the cec-gpio driver (when the CEC line is directly
+connected to a pull-up GPIO line) and the AllWinner A10/A20 drm driver
+support this framework.
+
+If ``CONFIG_CEC_PIN_ERROR_INJ`` is enabled, then error injection is available
+through debugfs. Specifically, in ``/sys/kernel/debug/cec/cecX/`` there is
+now an ``error-inj`` file.
+
+.. note::
+
+    The error injection commands are not a stable ABI and may change in the
+    future.
+
+With ``cat error-inj`` you can see both the possible commands and the current
+error injection status::
+
+	$ cat /sys/kernel/debug/cec/cec0/error-inj
+	# Clear error injections:
+	#   clear          clear all rx and tx error injections
+	#   rx-clear       clear all rx error injections

+	#   tx-custom-pulse                    transmit the custom pulse once the bus is idle
+	#

+	# <usecs>    microseconds (0-10000000, default 1000)
+
+	clear
+
+You can write error injection commands to ``error-inj`` using
+``echo 'cmd' >error-inj`` or ``cat cmd.txt >error-inj``. The ``cat error-inj``
+output contains the current error commands. You can save the output to a file
+and use it as an input to ``error-inj`` later.
+
+Basic Syntax
+------------
+
+Leading spaces/tabs are ignored. If the next character is a ``#`` or the end
+of the line was reached, then the whole line is ignored. Otherwise a command
+is expected.
+
+The error injection commands fall in two main groups: those relating to
+receiving CEC messages and those relating to transmitting CEC messages. In
+addition, there are commands to clear existing error injection commands and
+to create custom pulses on the CEC bus.
+
+Most error injection commands can be executed for specific CEC opcodes or for
+all opcodes (``any``). Each command also has a 'mode' which can be ``off``
+(can be used to turn off an existing error injection command), ``once``
+(the default) which will trigger the error injection only once for the next
+received or transmitted message, ``always`` to always trigger the error
+injection and ``toggle`` to toggle the error injection on or off for every
+transmit or receive.
+
+So '``any rx-nack``' will NACK the next received CEC message,
+'``any,always rx-nack``' will NACK all received CEC messages and
+'``0x82,toggle rx-nack``' will only NACK if an Active Source message was
+received and do that only for every other received message.
+
+After an error was injected with mode ``once`` the error injection command
+is cleared automatically, so ``once`` is a one-time deal.
+
+All combinations of ``<op>`` and error injection commands can co-exist. So
+this is fine::
+
+	0x9e tx-add-bytes 1
+	0x9e tx-early-eom
+	0x9f tx-add-bytes 2
+	any rx-nack
+
+All four error injection commands will be active simultaneously.
+
+However, if the same ``<op>`` and command combination is specified,
+but with different arguments::
+
+	0x9e tx-add-bytes 1
+	0x9e tx-add-bytes 2
+
+Then the second will overwrite the first.
+
+Clear Error Injections
+----------------------
+
+``clear``
+    Clear all error injections.
+
+``rx-clear``
+    Clear all receive error injections
+
+``tx-clear``
+    Clear all transmit error injections
+
+``<op> clear``
+    Clear all error injections for the given opcode.
+
+``<op> rx-clear``
+    Clear all receive error injections for the given opcode.
+
+``<op> tx-clear``
+    Clear all transmit error injections for the given opcode.
+
+Receive Messages
+----------------
+
+``<op>[,<mode>] rx-nack``
+    NACK broadcast messages and messages directed to this CEC adapter.
+    Every byte of the message will be NACKed in case the transmitter
+    keeps transmitting after the first byte was NACKed.
+
+``<op>[,<mode>] rx-low-drive <bit>``
+    Force a Low Drive condition at this bit position. If <op> specifies
+    a specific CEC opcode then the bit position must be at least 18,
+    otherwise the opcode hasn't been received yet. This tests if the
+    transmitter can handle the Low Drive condition correctly and reports
+    the error correctly. Note that a Low Drive in the first 4 bits can also
+    be interpreted as an Arbitration Lost condition by the transmitter.
+    This is implementation dependent.
+
+``<op>[,<mode>] rx-add-byte``
+    Add a spurious 0x55 byte to the received CEC message, provided
+    the message was 15 bytes long or less. This is useful to test
+    the high-level protocol since spurious bytes should be ignored.
+
+``<op>[,<mode>] rx-remove-byte``
+    Remove the last byte from the received CEC message, provided it
+    was at least 2 bytes long. This is useful to test the high-level
+    protocol since messages that are too short should be ignored.
+
+``<op>[,<mode>] rx-arb-lost <poll>``
+    Generate a POLL message to trigger an Arbitration Lost condition.
+    This command is only allowed for ``<op>`` values of ``next`` or ``all``.
+    As soon as a start bit has been received the CEC adapter will switch
+    to transmit mode and it will transmit a POLL message. By default this is
+    0x0f, but it can also be specified explicitly via the ``<poll>`` argument.
+
+    This command can be used to test the Arbitration Lost condition in
+    the remote CEC transmitter. Arbitration happens when two CEC adapters
+    start sending a message at the same time. In that case the initiator
+    with the most leading zeroes wins and the other transmitter has to
+    stop transmitting ('Arbitration Lost'). This is very hard to test,
+    except by using this error injection command.
+
+    This does not work if the remote CEC transmitter has logical address
+    0 ('TV') since that will always win.
+
+Transmit Messages
+-----------------
+
+``tx-ignore-nack-until-eom``
+    This setting changes the behavior of transmitting CEC messages. Normally
+    as soon as the receiver NACKs a byte the transmit will stop, but the
+    specification also allows that the full message is transmitted and only
+    at the end will the transmitter look at the ACK bit. This is not
+    recommended behavior since there is no point in keeping the CEC bus busy
+    for longer than is strictly needed. Especially given how slow the bus is.
+
+    This setting can be used to test how well a receiver deals with
+    transmitters that ignore NACKs until the very end of the message.
+
+``<op>[,<mode>] tx-no-eom``
+    Don't set the EOM bit. Normally the last byte of the message has the EOM
+    (End-Of-Message) bit set. With this command the transmit will just stop
+    without ever sending an EOM. This can be used to test how a receiver
+    handles this case. Normally receivers have a time-out after which
+    they will go back to the Idle state.
+
+``<op>[,<mode>] tx-early-eom``
+    Set the EOM bit one byte too soon. This obviously only works for messages
+    of two bytes or more. The EOM bit will be set for the second-to-last byte
+    and not for the final byte. The receiver should ignore the last byte in
+    this case. Since the resulting message is likely to be too short for this
+    same reason the whole message is typically ignored. The receiver should be
+    in Idle state after the last byte was transmitted.
+
+``<op>[,<mode>] tx-add-bytes <num>``
+    Append ``<num>`` (1-255) spurious bytes to the message. The extra bytes
+    have the value of the byte position in the message. So if you transmit a
+    two byte message (e.g. a Get CEC Version message) and add 2 bytes, then
+    the full message received by the remote CEC adapter is
+    ``0x40 0x9f 0x02 0x03``.
+
+    This command can be used to test buffer overflows in the receiver. E.g.
+    what does it do when it receives more than the maximum message size of 16
+    bytes.
+
+``<op>[,<mode>] tx-remove-byte``
+    Drop the last byte from the message, provided the message is at least
+    two bytes long. The receiver should ignore messages that are too short.
+
+``<op>[,<mode>] tx-short-bit <bit>``
+    Make this bit period shorter than allowed. The bit position cannot be
+    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
+    must be at least 18, otherwise the opcode hasn't been received yet.
+    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
+    With this command the period of this bit is 1.8 milliseconds, this is
+    done by reducing the time the CEC bus is high. This bit period is less
+    than is allowed and the receiver should respond with a Low Drive
+    condition.
+
+    This command is ignored for 0 bits in bit positions 0 to 3. This is
+    because the receiver also looks for an Arbitration Lost condition in
+    those first four bits and it is undefined what will happen if it
+    sees a too-short 0 bit.
+
+``<op>[,<mode>] tx-long-bit <bit>``
+    Make this bit period longer than is valid. The bit position cannot be
+    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
+    must be at least 18, otherwise the opcode hasn't been received yet.
+    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
+    With this command the period of this bit is 2.9 milliseconds, this is
+    done by increasing the time the CEC bus is high.
+
+    Even though this bit period is longer than is valid it is undefined what
+    a receiver will do. It might just accept it, or it might time out and
+    return to Idle state. Unfortunately the CEC specification is silent about
+    this.
+
+    This command is ignored for 0 bits in bit positions 0 to 3. This is
+    because the receiver also looks for an Arbitration Lost condition in
+    those first four bits and it is undefined what will happen if it
+    sees a too-long 0 bit.
+
+``<op>[,<mode>] tx-short-start``
+    Make this start bit period shorter than allowed. Normally the period of
+    a start bit is between 4.3 and 4.7 milliseconds. With this command the
+    period of the start bit is 4.1 milliseconds, this is done by reducing
+    the time the CEC bus is high. This start bit period is less than is
+    allowed and the receiver should return to Idle state when this is detected.
+
+``<op>[,<mode>] tx-long-start``
+    Make this start bit period longer than is valid. Normally the period of
+    a start bit is between 4.3 and 4.7 milliseconds. With this command the
+    period of the start bit is 5 milliseconds, this is done by increasing
+    the time the CEC bus is high. This start bit period is more than is
+    valid and the receiver should return to Idle state when this is detected.
+
+    Even though this start bit period is longer than is valid it is undefined
+    what a receiver will do. It might just accept it, or it might time out and
+    return to Idle state. Unfortunately the CEC specification is silent about
+    this.
+
+``<op>[,<mode>] tx-last-bit <bit>``
+    Just stop transmitting after this bit.  If <op> specifies a specific CEC
+    opcode then the bit position must be at least 18, otherwise the opcode
+    hasn't been received yet. This command can be used to test how the receiver
+    reacts when a message just suddenly stops. It should time out and go back
+    to Idle state.
+
+``<op>[,<mode>] tx-low-drive <bit>``
+    Force a Low Drive condition at this bit position. If <op> specifies a
+    specific CEC opcode then the bit position must be at least 18, otherwise
+    the opcode hasn't been received yet. This can be used to test how the
+    receiver handles Low Drive conditions. Note that if this happens at bit
+    positions 0-3 the receiver can interpret this as an Arbitration Lost
+    condition. This is implementation dependent.
+
+Custom Pulses
+-------------
+
+``tx-custom-low-usecs <usecs>``
+    This defines the duration in microseconds that the custom pulse pulls
+    the CEC line low. The default is 1000 microseconds.
+
+``tx-custom-high-usecs <usecs>``
+    This defines the duration in microseconds that the custom pulse keeps the
+    CEC line high (unless another CEC adapter pulls it low in that time).
+    The default is 1000 microseconds. The total period of the custom pulse is
+    ``tx-custom-low-usecs + tx-custom-high-usecs``.
+
+``<op>[,<mode>] tx-custom-bit <bit>``
+    Send the custom bit instead of a regular data bit. The bit position cannot
+    be an Ack bit.  If <op> specifies a specific CEC opcode then the bit
+    position must be at least 18, otherwise the opcode hasn't been received yet.
+
+``<op>[,<mode>] tx-custom-start``
+    Send the custom bit instead of a regular start bit.
+
+``tx-custom-pulse``
+    Transmit a single custom pulse as soon as the CEC bus is idle.

+The cx2341x driver
+==================
+
+Non-compressed file format
+--------------------------
+
+The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
+format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
+for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
+be more accurate.
+
+The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
+four pixels.
+
+The data is encoded as two macroblock planes, the first containing the Y
+values, the second containing UV macroblocks.
+
+The Y plane is divided into blocks of 16x16 pixels from left to right
+and from top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block, the
+second 16 bytes are the second line of the top-left block, etc. After
+transmitting this block the first line of the block on the right to the
+first block is transmitted, etc.
+
+The UV plane is divided into blocks of 16x8 UV values going from left
+to right, top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block and
+contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
+second line of 8 UV pairs of the top-left block, etc. After transmitting
+this block the first line of the block on the right to the first block is
+transmitted, etc.
+
+The code below is given as an example on how to convert HM12 to separate
+Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
+
+The width of a frame is always 720 pixels, regardless of the actual specified
+width.
+
+If the height is not a multiple of 32 lines, then the captured video is
+missing macroblocks at the end and is unusable. So the height must be a
+multiple of 32.

+Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
+---------------------------------------------------------
+
+Author: Hans Verkuil <hverkuil@xs4all.nl>
+
+
+This section describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
+embedded in an MPEG-2 program stream. This format is in part dictated by some
+hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
+chips), in particular a maximum size for the VBI data. Anything longer is cut
+off when the MPEG stream is played back through the cx23415.
+
+The advantage of this format is it is very compact and that all VBI data for
+all lines can be stored while still fitting within the maximum allowed size.
+
+The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
+4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
+header and a 42 bytes payload each. Anything beyond this limit is cut off by
+the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
+for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
+signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
+If all lines are used, then there is no longer room for the bitmask. To solve this
+two different magic numbers were introduced:
+
+'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
+unsigned long denote which lines of the first field are captured. Bits 18-31 of
+the first unsigned long and bits 0-3 of the second unsigned long are used for the
+second field.
+
+'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
+implies that the bitmasks are 0xffffffff and 0xf.
+
+After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
+captured VBI lines start:
+
+For each line the least significant 4 bits of the first byte contain the data type.
+Possible values are shown in the table below. The payload is in the following 42
+bytes.
+
+Here is the list of possible data types:
+
+.. code-block:: c
+
+	#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
+	#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
+	#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
+	#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

+=========================
+i.MX Video Capture Driver
+=========================
+
+Events
+======
+
+.. _imx_api_ipuX_csiY:
+
+ipuX_csiY
+---------
+
+This subdev can generate the following event when enabling the second
+IDMAC source pad:
+
+- V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR
+
+The user application can subscribe to this event from the ipuX_csiY
+subdev node. This event is generated by the Frame Interval Monitor
+(see below for more on the FIM).
+
+Controls
+========
+
+.. _imx_api_FIM:
+
+Frame Interval Monitor in ipuX_csiY
+-----------------------------------
+
+The adv718x decoders can occasionally send corrupt fields during
+NTSC/PAL signal re-sync (too little or too many video lines). When
+this happens, the IPU triggers a mechanism to re-establish vertical
+sync by adding 1 dummy line every frame, which causes a rolling effect
+from image to image, and can last a long time before a stable image is
+recovered. Or sometimes the mechanism doesn't work at all, causing a
+permanent split image (one frame contains lines from two consecutive
+captured images).
+
+From experiment it was found that during image rolling, the frame
+intervals (elapsed time between two EOF's) drop below the nominal
+value for the current standard, by about one frame time (60 usec),
+and remain at that value until rolling stops.
+
+While the reason for this observation isn't known (the IPU dummy
+line mechanism should show an increase in the intervals by 1 line
+time every frame, not a fixed value), we can use it to detect the
+corrupt fields using a frame interval monitor. If the FIM detects a
+bad frame interval, the ipuX_csiY subdev will send the event
+V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR. Userland can register with
+the FIM event notification on the ipuX_csiY subdev device node.
+Userland can issue a streaming restart when this event is received
+to correct the rolling/split image.
+
+The ipuX_csiY subdev includes custom controls to tweak some dials for
+FIM. If one of these controls is changed during streaming, the FIM will
+be reset and will continue at the new settings.
+
+- V4L2_CID_IMX_FIM_ENABLE
+
+Enable/disable the FIM.
+
+- V4L2_CID_IMX_FIM_NUM
+
+How many frame interval measurements to average before comparing against
+the nominal frame interval reported by the sensor. This can reduce noise
+caused by interrupt latency.
+
+- V4L2_CID_IMX_FIM_TOLERANCE_MIN
+
+If the averaged intervals fall outside nominal by this amount, in
+microseconds, the V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR event is sent.
+
+- V4L2_CID_IMX_FIM_TOLERANCE_MAX
+
+If any intervals are higher than this value, those samples are
+discarded and do not enter into the average. This can be used to
+discard really high interval errors that might be due to interrupt
+latency from high system load.
+
+- V4L2_CID_IMX_FIM_NUM_SKIP
+
+How many frames to skip after a FIM reset or stream restart before
+FIM begins to average intervals.
+
+- V4L2_CID_IMX_FIM_ICAP_CHANNEL / V4L2_CID_IMX_FIM_ICAP_EDGE
+
+These controls will configure an input capture channel as the method
+for measuring frame intervals. This is superior to the default method
+of measuring frame intervals via EOF interrupt, since it is not subject
+to uncertainty errors introduced by interrupt latency.
+
+Input capture requires hardware support. A VSYNC signal must be routed
+to one of the i.MX6 input capture channel pads.
+
+V4L2_CID_IMX_FIM_ICAP_CHANNEL configures which i.MX6 input capture
+channel to use. This must be 0 or 1.
+
+V4L2_CID_IMX_FIM_ICAP_EDGE configures which signal edge will trigger
+input capture events. By default the input capture method is disabled
+with a value of IRQ_TYPE_NONE. Set this control to IRQ_TYPE_EDGE_RISING,
+IRQ_TYPE_EDGE_FALLING, or IRQ_TYPE_EDGE_BOTH to enable input capture,
+triggered on the given signal edge(s).
+
+When input capture is disabled, frame intervals will be measured via
+EOF interrupt.

+
+Private API
+-----------
+
+The driver supports frame grabbing with the video4linux API,
+so all video4linux tools (like xawtv) should work with this driver.
+
+Besides the video4linux interface, the driver has a private interface
+for accessing the Motion Eye extended parameters (camera sharpness,
+agc, video framerate), the snapshot and the MJPEG capture facilities.
+
+This interface consists of several ioctls (prototypes and structures
+can be found in include/linux/meye.h):
+
+MEYEIOC_G_PARAMS and MEYEIOC_S_PARAMS
+	Get and set the extended parameters of the motion eye camera.
+	The user should always query the current parameters with
+	MEYEIOC_G_PARAMS, change what he likes and then issue the
+	MEYEIOC_S_PARAMS call (checking for -EINVAL). The extended
+	parameters are described by the meye_params structure.
+
+
+MEYEIOC_QBUF_CAPT
+	Queue a buffer for capture (the buffers must have been
+	obtained with a VIDIOCGMBUF call and mmap'ed by the
+	application). The argument to MEYEIOC_QBUF_CAPT is the
+	buffer number to queue (or -1 to end capture). The first
+	call to MEYEIOC_QBUF_CAPT starts the streaming capture.
+
+MEYEIOC_SYNC
+	Takes as an argument the buffer number you want to sync.
+	This ioctl blocks until the buffer is filled and ready
+	for the application to use. It returns the buffer size.
+
+MEYEIOC_STILLCAPT and MEYEIOC_STILLJCAPT
+	Takes a snapshot in an uncompressed or compressed jpeg format.
+	This ioctl blocks until the snapshot is done and returns (for
+	jpeg snapshot) the size of the image. The image data is
+	available from the first mmap'ed buffer.
+
+Look at the 'motioneye' application code for an actual example.

+OMAP 3 Image Signal Processor (ISP) driver

+
+
+Events
+------
+
+The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and
+statistics (AEWB, AF and histogram) subdevs.
+
+The CCDC subdev produces V4L2_EVENT_FRAME_SYNC type event on HS_VS
+interrupt which is used to signal frame start. Earlier version of this
+driver used V4L2_EVENT_OMAP3ISP_HS_VS for this purpose. The event is
+triggered exactly when the reception of the first line of the frame starts
+in the CCDC module. The event can be subscribed on the CCDC subdev.
+
+(When using parallel interface one must pay account to correct configuration
+of the VS signal polarity. This is automatically correct when using the serial
+receivers.)
+
+Each of the statistics subdevs is able to produce events. An event is
+generated whenever a statistics buffer can be dequeued by a user space
+application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available
+are:
+
+- V4L2_EVENT_OMAP3ISP_AEWB
+- V4L2_EVENT_OMAP3ISP_AF
+- V4L2_EVENT_OMAP3ISP_HIST
+
+The type of the event data is struct omap3isp_stat_event_status for these
+ioctls. If there is an error calculating the statistics, there will be an
+event as usual, but no related statistics buffer. In this case
+omap3isp_stat_event_status.buf_err is set to non-zero.
+
+
+Private IOCTLs
+--------------
+
+The OMAP 3 ISP driver supports standard V4L2 IOCTLs and controls where
+possible and practical. Much of the functions provided by the ISP, however,
+does not fall under the standard IOCTLs --- gamma tables and configuration of
+statistics collection are examples of such.
+
+In general, there is a private ioctl for configuring each of the blocks
+containing hardware-dependent functions.
+
+The following private IOCTLs are supported:
+
+- VIDIOC_OMAP3ISP_CCDC_CFG
+- VIDIOC_OMAP3ISP_PRV_CFG
+- VIDIOC_OMAP3ISP_AEWB_CFG
+- VIDIOC_OMAP3ISP_HIST_CFG
+- VIDIOC_OMAP3ISP_AF_CFG
+- VIDIOC_OMAP3ISP_STAT_REQ
+- VIDIOC_OMAP3ISP_STAT_EN
+
+The parameter structures used by these ioctls are described in
+include/linux/omap3isp.h. The detailed functions of the ISP itself related to
+a given ISP block is described in the Technical Reference Manuals (TRMs) ---
+see the end of the document for those.
+
+While it is possible to use the ISP driver without any use of these private
+IOCTLs it is not possible to obtain optimal image quality this way. The AEWB,
+AF and histogram modules cannot be used without configuring them using the
+appropriate private IOCTLs.
+
+
+CCDC and preview block IOCTLs
+-----------------------------
+
+The VIDIOC_OMAP3ISP_CCDC_CFG and VIDIOC_OMAP3ISP_PRV_CFG IOCTLs are used to
+configure, enable and disable functions in the CCDC and preview blocks,
+respectively. Both IOCTLs control several functions in the blocks they
+control. VIDIOC_OMAP3ISP_CCDC_CFG IOCTL accepts a pointer to struct
+omap3isp_ccdc_update_config as its argument. Similarly VIDIOC_OMAP3ISP_PRV_CFG
+accepts a pointer to struct omap3isp_prev_update_config. The definition of
+both structures is available in [#]_.
+
+The update field in the structures tells whether to update the configuration
+for the specific function and the flag tells whether to enable or disable the
+function.
+
+The update and flag bit masks accept the following values. Each separate
+functions in the CCDC and preview blocks is associated with a flag (either
+disable or enable; part of the flag field in the structure) and a pointer to
+configuration data for the function.
+
+Valid values for the update and flag fields are listed here for
+VIDIOC_OMAP3ISP_CCDC_CFG. Values may be or'ed to configure more than one
+function in the same IOCTL call.
+
+- OMAP3ISP_CCDC_ALAW
+- OMAP3ISP_CCDC_LPF
+- OMAP3ISP_CCDC_BLCLAMP
+- OMAP3ISP_CCDC_BCOMP
+- OMAP3ISP_CCDC_FPC
+- OMAP3ISP_CCDC_CULL
+- OMAP3ISP_CCDC_CONFIG_LSC
+- OMAP3ISP_CCDC_TBL_LSC
+
+The corresponding values for the VIDIOC_OMAP3ISP_PRV_CFG are here:
+
+- OMAP3ISP_PREV_LUMAENH
+- OMAP3ISP_PREV_INVALAW
+- OMAP3ISP_PREV_HRZ_MED
+- OMAP3ISP_PREV_CFA
+- OMAP3ISP_PREV_CHROMA_SUPP
+- OMAP3ISP_PREV_WB
+- OMAP3ISP_PREV_BLKADJ
+- OMAP3ISP_PREV_RGB2RGB
+- OMAP3ISP_PREV_COLOR_CONV
+- OMAP3ISP_PREV_YC_LIMIT
+- OMAP3ISP_PREV_DEFECT_COR
+- OMAP3ISP_PREV_GAMMABYPASS
+- OMAP3ISP_PREV_DRK_FRM_CAPTURE
+- OMAP3ISP_PREV_DRK_FRM_SUBTRACT
+- OMAP3ISP_PREV_LENS_SHADING
+- OMAP3ISP_PREV_NF
+- OMAP3ISP_PREV_GAMMA
+
+The associated configuration pointer for the function may not be NULL when
+enabling the function. When disabling a function the configuration pointer is
+ignored.
+
+
+Statistic blocks IOCTLs
+-----------------------
+
+The statistics subdevs do offer more dynamic configuration options than the
+other subdevs. They can be enabled, disable and reconfigured when the pipeline
+is in streaming state.
+
+The statistics blocks always get the input image data from the CCDC (as the
+histogram memory read isn't implemented). The statistics are dequeueable by
+the user from the statistics subdev nodes using private IOCTLs.
+
+The private IOCTLs offered by the AEWB, AF and histogram subdevs are heavily
+reflected by the register level interface offered by the ISP hardware. There
+are aspects that are purely related to the driver implementation and these are
+discussed next.
+
+VIDIOC_OMAP3ISP_STAT_EN
+-----------------------
+
+This private IOCTL enables/disables a statistic module. If this request is
+done before streaming, it will take effect as soon as the pipeline starts to
+stream.  If the pipeline is already streaming, it will take effect as soon as
+the CCDC becomes idle.
+
+VIDIOC_OMAP3ISP_AEWB_CFG, VIDIOC_OMAP3ISP_HIST_CFG and VIDIOC_OMAP3ISP_AF_CFG
+-----------------------------------------------------------------------------
+
+Those IOCTLs are used to configure the modules. They require user applications
+to have an in-depth knowledge of the hardware. Most of the fields explanation
+can be found on OMAP's TRMs. The two following fields common to all the above
+configure private IOCTLs require explanation for better understanding as they
+are not part of the TRM.
+
+omap3isp_[h3a_af/h3a_aewb/hist]\_config.buf_size:
+
+The modules handle their buffers internally. The necessary buffer size for the
+module's data output depends on the requested configuration. Although the
+driver supports reconfiguration while streaming, it does not support a
+reconfiguration which requires bigger buffer size than what is already
+internally allocated if the module is enabled. It will return -EBUSY on this
+case. In order to avoid such condition, either disable/reconfigure/enable the
+module or request the necessary buffer size during the first configuration
+while the module is disabled.
+
+The internal buffer size allocation considers the requested configuration's
+minimum buffer size and the value set on buf_size field. If buf_size field is
+out of [minimum, maximum] buffer size range, it's clamped to fit in there.
+The driver then selects the biggest value. The corrected buf_size value is
+written back to user application.
+
+omap3isp_[h3a_af/h3a_aewb/hist]\_config.config_counter:
+
+As the configuration doesn't take effect synchronously to the request, the
+driver must provide a way to track this information to provide more accurate
+data. After a configuration is requested, the config_counter returned to user
+space application will be an unique value associated to that request. When
+user application receives an event for buffer availability or when a new
+buffer is requested, this config_counter is used to match a buffer data and a
+configuration.
+
+VIDIOC_OMAP3ISP_STAT_REQ
+------------------------
+
+Send to user space the oldest data available in the internal buffer queue and
+discards such buffer afterwards. The field omap3isp_stat_data.frame_number
+matches with the video buffer's field_count.

+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+Description
+-----------
+
+This system call opens a named audio device (e.g.
+/dev/dvb/adapter0/audio0) for subsequent use. When an open() call has
+succeeded, the device will be ready for use. The significance of
+blocking or non-blocking mode is described in the documentation for
+functions where there is a difference. It does not affect the semantics
+of the open() call itself. A device opened in blocking mode can later be
+put into non-blocking mode (and vice versa) using the F_SETFL command
+of the fcntl system call. This is a standard system call, documented in
+the Linux manual page for fcntl. Only one user can open the Audio Device
+in O_RDWR mode. All other attempts to open the device in this mode will
+fail, and an error code will be returned. If the Audio Device is opened
+in O_RDONLY mode, the only ioctl call that can be used is
+AUDIO_GET_STATUS. All other call will return with an error code.

+Digital TV Audio Device
+#######################
+
+The Digital TV audio device controls the MPEG2 audio decoder of the Digital
+TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
+types and and ioctl definitions can be accessed by including
+``linux/dvb/audio.h`` in your application.
+
+Please note that some Digital TV cards don’t have their own MPEG decoder, which
+results in the omission of the audio and video device.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+Audio Data Types
+****************
+
+This section describes the structures, data types and defines used when
+talking to the audio device.
+
+.. c:type:: audio_stream_source
+
+The audio stream source is set through the AUDIO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demux) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_SOURCE_DEMUX,
+	AUDIO_SOURCE_MEMORY
+    } audio_stream_source_t;
+
+AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+AUDIO_SOURCE_MEMORY is selected the stream comes from the application
+through the ``write()`` system call.
+
+
+.. c:type:: audio_play_state
+
+The following values can be returned by the AUDIO_GET_STATUS call
+representing the state of audio playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STOPPED,
+	AUDIO_PLAYING,
+	AUDIO_PAUSED
+    } audio_play_state_t;
+
+
+.. c:type:: audio_channel_select
+
+The audio channel selected via AUDIO_CHANNEL_SELECT is determined by
+the following values.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STEREO,
+	AUDIO_MONO_LEFT,
+	AUDIO_MONO_RIGHT,
+	AUDIO_MONO,
+	AUDIO_STEREO_SWAPPED
+    } audio_channel_select_t;
+
+
+.. c:type:: audio_status
+
+The AUDIO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+    typedef struct audio_status {
+	boolean AV_sync_state;
+	boolean mute_state;
+	audio_play_state_t play_state;
+	audio_stream_source_t stream_source;
+	audio_channel_select_t channel_select;
+	boolean bypass_mode;
+	audio_mixer_t mixer_state;
+    } audio_status_t;
+
+
+.. c:type:: audio_mixer
+
+The following structure is used by the AUDIO_SET_MIXER call to set the
+audio volume.
+
+
+.. code-block:: c
+
+    typedef struct audio_mixer {
+	unsigned int volume_left;
+	unsigned int volume_right;
+    } audio_mixer_t;

+
+
+Synopsis
+--------
+
+.. c:function:: int open(const char *name, int flags)
+    :name: dvb-ca-open
+
+
+Arguments
+---------
+
+``name``
+  Name of specific Digital TV CA device.
+
+``flags``
+  A bit-wise OR of the following flags:
+
+.. tabularcolumns:: |p{2.5cm}|p{15.0cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+    :widths: 1 16
+
+    -  - ``O_RDONLY``
+       - read-only access
+
+    -  - ``O_RDWR``
+       - read/write access
+
+    -  - ``O_NONBLOCK``
+       - open in non-blocking mode
+         (blocking mode is the default)
+
+
+Description
+-----------
+
+This system call opens a named ca device (e.g. ``/dev/dvb/adapter?/ca?``)
+for subsequent use.
+
+When an ``open()`` call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the ``open()`` call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the ``F_SETFL`` command of the ``fcntl`` system call. This is a
+standard system call, documented in the Linux manual page for fcntl.
+Only one user can open the CA Device in ``O_RDWR`` mode. All other
+attempts to open the device in this mode will fail, and an error code
+will be returned.
+
+
+Return Value
+------------
+
+
+On success 0 is returned.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.
+
+Generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+The High level CI API
+=====================
+
+.. note::
+
+   This documentation is outdated.
+
+This document describes the high level CI API as in accordance to the
+Linux DVB API.
+
+
+With the High Level CI approach any new card with almost any random
+architecture can be implemented with this style, the definitions
+inside the switch statement can be easily adapted for any card, thereby
+eliminating the need for any additional ioctls.
+
+The disadvantage is that the driver/hardware has to manage the rest. For
+the application programmer it would be as simple as sending/receiving an
+array to/from the CI ioctls as defined in the Linux DVB API. No changes
+have been made in the API to accommodate this feature.
+
+
+Why the need for another CI interface?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is one of the most commonly asked question. Well a nice question.
+Strictly speaking this is not a new interface.
+
+The CI interface is defined in the DVB API in ca.h as:
+
+.. code-block:: c
+
+	typedef struct ca_slot_info {
+		int num;               /* slot number */
+
+		int type;              /* CA interface this slot supports */
+	#define CA_CI            1     /* CI high level interface */
+	#define CA_CI_LINK       2     /* CI link layer level interface */
+	#define CA_CI_PHYS       4     /* CI physical layer level interface */
+	#define CA_DESCR         8     /* built-in descrambler */
+	#define CA_SC          128     /* simple smart card interface */
+
+		unsigned int flags;
+	#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
+	#define CA_CI_MODULE_READY   2
+	} ca_slot_info_t;
+
+This CI interface follows the CI high level interface, which is not
+implemented by most applications. Hence this area is revisited.
+
+This CI interface is quite different in the case that it tries to
+accommodate all other CI based devices, that fall into the other categories.
+
+This means that this CI interface handles the EN50221 style tags in the
+Application layer only and no session management is taken care of by the
+application. The driver/hardware will take care of all that.
+
+This interface is purely an EN50221 interface exchanging APDU's. This
+means that no session management, link layer or a transport layer do
+exist in this case in the application to driver communication. It is
+as simple as that. The driver/hardware has to take care of that.
+
+With this High Level CI interface, the interface can be defined with the
+regular ioctls.
+
+All these ioctls are also valid for the High level CI interface
+
+#define CA_RESET          _IO('o', 128)
+#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
+#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)
+#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
+#define CA_GET_MSG        _IOR('o', 132, ca_msg_t)
+#define CA_SEND_MSG       _IOW('o', 133, ca_msg_t)
+#define CA_SET_DESCR      _IOW('o', 134, ca_descr_t)
+
+
+On querying the device, the device yields information thus:
+
+.. code-block:: none
+
+	CA_GET_SLOT_INFO
+	----------------------------
+	Command = [info]
+	APP: Number=[1]
+	APP: Type=[1]

+	----------------------------
+	Descriptors(Program Level)=[ 09 06 06 04 05 50 ff f1]
+	Found CA descriptor @ program level
+
+	(20) ES type=[2] ES pid=[201]  ES length =[0 (0x0)]
+	(25) ES type=[4] ES pid=[301]  ES length =[0 (0x0)]
+	ca_message length is 25 (0x19) bytes
+	EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
+
+
+Not all ioctl's are implemented in the driver from the API, the other
+features of the hardware that cannot be implemented by the API are achieved
+using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
+used to exchange the data to maintain compatibility with other hardware.
+
+.. code-block:: c
+
+	/* a message to/from a CI-CAM */
+	typedef struct ca_msg {
+		unsigned int index;
+		unsigned int type;
+		unsigned int length;
+		unsigned char msg[256];
+	} ca_msg_t;
+
+
+The flow of data can be described thus,
+
+.. code-block:: none

+DMX_EXPBUF - Export a buffer as a DMABUF file descriptor.
+
+.. warning:: this API is still experimental
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, DMX_EXPBUF, struct dmx_exportbuffer *argp )
+    :name: DMX_EXPBUF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the memory mapping I/O method.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
+Applications must set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
+(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported.
+All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`DMX_EXPBUF` calls.
+
+After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
+driver, on success. This is a DMABUF file descriptor. The application may
+pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
+file when it is no longer used to allow the associated memory to be reclaimed.
+
+
+Examples
+========
+
+
+.. code-block:: c
+
+    int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
+    {
+	struct dmx_exportbuffer expbuf;
+
+	memset(&expbuf, 0, sizeof(expbuf));
+	expbuf.type = bt;
+	expbuf.index = index;
+	if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
+	    perror("DMX_EXPBUF");
+	    return -1;
+	}
+
+	*dmafd = expbuf.fd;
+
+	return 0;
+    }
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    A queue is not in MMAP mode or DMABUF exporting is not supported or
+    ``flags`` or ``index`` fields are invalid.

+
+
+Description
+-----------
+
+This system call, used with a device name of ``/dev/dvb/adapter?/demux?``,
+allocates a new filter and returns a handle which can be used for
+subsequent control of that filter. This call has to be made for each
+filter to be used, i.e. every returned file descriptor is a reference to
+a single filter. ``/dev/dvb/adapter?/dvr?`` is a logical device to be used
+for retrieving Transport Streams for digital video recording. When
+reading from this device a transport stream containing the packets from
+all PES filters set in the corresponding demux device
+(``/dev/dvb/adapter?/demux?``) having the output set to ``DMX_OUT_TS_TAP``.
+A recorded Transport Stream is replayed by writing to this device.
+
+The significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the ``open()`` call itself. A device opened
+in blocking mode can later be put into non-blocking mode (and vice versa)
+using the ``F_SETFL`` command of the fcntl system call.
+
+
+Return Value
+------------
+
+On success 0 is returned.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.

+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+    :name: dmx-mmap
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be a multiple of the
+    DVB packet length (188, on most drivers).
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note::
+
+       The Linux Digital TV applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``offset``
+    Offset of the buffer in device memory, as returned by
+    :ref:`DMX_QUERYBUF` ioctl.
+
+
+Description
+===========
+
+The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
+:ref:`DMX_REQBUFS` ioctl before they can be queried.
+
+To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.
+
+EACCES
+    ``fd`` is not open for reading and writing.
+
+EINVAL
+    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+    The ``flags`` or ``prot`` value is not supported.
+
+    No buffers have been allocated with the
+    :ref:`DMX_REQBUFS` ioctl.
+
+ENOMEM
+    Not enough physical or virtual memory was available to complete the
+    request.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_buffer`.
+
+
+Description
+===========
+
+Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``index`` field. Valid index
+numbers range from zero to the number of buffers allocated with
+:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`dmx_buffer` returned
+by a :ref:`DMX_QUERYBUF` ioctl will do as well.
+
+When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
+memory pages of the buffer in physical memory, so they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+the device is closed.
+
+Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
+(capturing) buffer from the driver's outgoing queue.
+They just set the ``index`` field with the buffer ID to be queued.
+When ``DMX_DQBUF`` is called with a pointer to struct :c:type:`dmx_buffer`,
+the driver fills the remaining fields or returns an error code.
+
+By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`dmx_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EAGAIN
+    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+    buffer was in the outgoing queue.
+
+EINVAL
+    The ``index`` is out of bounds, or no buffers have been allocated yet.
+
+EIO
+    ``DMX_DQBUF`` failed due to an internal error. Can also indicate
+    temporary problems like signal loss or CRC errors.

+
+``argp``
+    Pointer to struct :c:type:`dmx_requestbuffers`.
+
+Description
+===========
+
+This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
+
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`dmx_requestbuffers` structure. They set the  ``count`` field
+to the desired number of buffers,  and ``size`` to the size of each
+buffer.
+
+When the ioctl is called with a pointer to this structure, the driver will
+attempt to allocate the requested number of buffers and it stores the actual
+number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. The actual allocated buffer size can is returned
+at ``size``, and can be smaller than what's requested.
+
+When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
+error code.
+
+Applications can call :ref:`DMX_REQBUFS` again to change the number of
+buffers, however this cannot succeed when any buffers are still mapped.
+A ``count`` value of zero frees all buffers, after aborting or finishing
+any DMA in progress.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EOPNOTSUPP
+    The  the requested I/O method is not supported.

+
+*******************
+frontend parameters
+*******************
+
+The kind of parameters passed to the frontend device for tuning depend
+on the kind of hardware you are using.
+
+The struct ``dvb_frontend_parameters`` uses a union with specific
+per-system parameters. However, as newer delivery systems required more
+data, the structure size weren't enough to fit, and just extending its
+size would break the existing applications. So, those parameters were
+replaced by the usage of
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+ioctl's. The new API is flexible enough to add new parameters to
+existing delivery systems, and to add newer delivery systems.
+
+So, newer applications should use
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+instead, in order to be able to support the newer System Delivery like
+DVB-S2, DVB-T2, DVB-C2, ISDB, etc.
+
+All kinds of parameters are combined as a union in the
+``dvb_frontend_parameters`` structure:
+
+
+.. code-block:: c
+
+    struct dvb_frontend_parameters {
+	uint32_t frequency;     /* (absolute) frequency in Hz for QAM/OFDM */
+		    /* intermediate frequency in kHz for QPSK */
+	fe_spectral_inversion_t inversion;
+	union {
+	    struct dvb_qpsk_parameters qpsk;
+	    struct dvb_qam_parameters  qam;
+	    struct dvb_ofdm_parameters ofdm;
+	    struct dvb_vsb_parameters  vsb;
+	} u;
+    };
+
+In the case of QPSK frontends the ``frequency`` field specifies the
+intermediate frequency, i.e. the offset which is effectively added to
+the local oscillator frequency (LOF) of the LNB. The intermediate
+frequency has to be specified in units of kHz. For QAM and OFDM
+frontends the ``frequency`` specifies the absolute frequency and is
+given in Hz.
+
+
+.. c:type:: dvb_qpsk_parameters
+
+QPSK parameters
+===============
+
+For satellite QPSK frontends you have to use the ``dvb_qpsk_parameters``
+structure:
+
+
+.. code-block:: c
+
+     struct dvb_qpsk_parameters {
+	 uint32_t        symbol_rate;  /* symbol rate in Symbols per second */
+	 fe_code_rate_t  fec_inner;    /* forward error correction (see above) */
+     };
+
+
+.. c:type:: dvb_qam_parameters
+
+QAM parameters
+==============
+
+for cable QAM frontend you use the ``dvb_qam_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_qam_parameters {
+	 uint32_t         symbol_rate; /* symbol rate in Symbols per second */
+	 fe_code_rate_t   fec_inner;   /* forward error correction (see above) */
+	 fe_modulation_t  modulation;  /* modulation type (see above) */
+     };
+
+
+.. c:type:: dvb_vsb_parameters
+
+VSB parameters
+==============
+
+ATSC frontends are supported by the ``dvb_vsb_parameters`` structure:
+
+
+.. code-block:: c
+
+    struct dvb_vsb_parameters {
+	fe_modulation_t modulation; /* modulation type (see above) */
+    };
+
+
+.. c:type:: dvb_ofdm_parameters
+
+OFDM parameters
+===============
+
+DVB-T frontends are supported by the ``dvb_ofdm_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_ofdm_parameters {
+	 fe_bandwidth_t      bandwidth;
+	 fe_code_rate_t      code_rate_HP;  /* high priority stream code rate */
+	 fe_code_rate_t      code_rate_LP;  /* low priority stream code rate */
+	 fe_modulation_t     constellation; /* modulation type (see above) */
+	 fe_transmit_mode_t  transmission_mode;
+	 fe_guard_interval_t guard_interval;
+	 fe_hierarchy_t      hierarchy_information;
+     };

+
+Tuning into a Digital TV physical channel and starting decoding it
+requires changing a set of parameters, in order to control the tuner,
+the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
+antenna subsystem via Satellite Equipment Control - SEC (on satellite
+systems). The actual parameters are specific to each particular digital
+TV standards, and may change as the digital TV specs evolves.
+
+In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
+union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
+ATSC delivery systems grouped there. The problem is that, as the second
+generation standards appeared, the size of such union was not big
+enough to group the structs that would be required for those new
+standards. Also, extending it would break userspace.
+
+So, the legacy union/struct based approach was deprecated, in favor
+of a properties set approach. On such approach,
+:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
+to setup the frontend and read its status.
+
+The actual action is determined by a set of dtv_property cmd/data pairs.
+With one single ioctl, is possible to get/set up to 64 properties.
+
+This section describes the new and recommended way to set the frontend,
+with supports all digital TV delivery systems.
+
+.. note::
+
+   1. On Linux DVB API version 3, setting a frontend was done via
+      struct :c:type:`dvb_frontend_parameters`.
+
+   2. Don't use DVB API version 3 calls on hardware with supports
+      newer standards. Such API provides no support or a very limited
+      support to new standards and/or new hardware.
+
+   3. Nowadays, most frontends support multiple delivery systems.
+      Only with DVB API version 5 calls it is possible to switch between
+      the multiple delivery systems supported by a frontend.
+
+   4. DVB API version 5 is also called *S2API*, as the first
+      new standard added to it was DVB-S2.
+
+**Example**: in order to set the hardware to tune into a DVB-C channel
+at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
+Mbauds, those properties should be sent to
+:ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` ioctl:
+
+  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` = SYS_DVBC_ANNEX_A
+
+  :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` = 651000000
+
+  :ref:`DTV_MODULATION <DTV-MODULATION>` = QAM_256
+
+  :ref:`DTV_INVERSION <DTV-INVERSION>` = INVERSION_AUTO
+
+  :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>` = 5217000
+
+  :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` = FEC_3_4
+
+  :ref:`DTV_TUNE <DTV-TUNE>`
+
+The code that would that would do the above is show in
+:ref:`dtv-prop-example`.

+This section describes each of them. Please notice, however, that only
+a subset of them are needed to setup a frontend.
+
+
+.. _DTV-UNDEFINED:
+
+DTV_UNDEFINED
+=============
+

+
+
+.. _DTV-FREQUENCY:
+
+DTV_FREQUENCY
+=============
+
+Frequency of the digital TV transponder/channel.
+
+.. note::
+
+  #. For satellite delivery systems, the frequency is in kHz.
+
+  #. For cable and terrestrial delivery systems, the frequency is in
+     Hz.
+
+  #. On most delivery systems, the frequency is the center frequency
+     of the transponder/channel. The exception is for ISDB-T, where
+     the main carrier has a 1/7 offset from the center.
+
+  #. For ISDB-T, the channels are usually transmitted with an offset of
+     about 143kHz. E.g. a valid frequency could be 474,143 kHz. The
+     stepping is  bound to the bandwidth of the channel which is
+     typically 6MHz.
+
+  #. In ISDB-Tsb, the channel consists of only one or three segments the
+     frequency step is 429kHz, 3*429 respectively.
+
+
+.. _DTV-MODULATION:
+
+DTV_MODULATION
+==============
+
+Specifies the frontend modulation type for delivery systems that
+supports more multiple modulations.
+
+The modulation can be one of the types defined by enum :c:type:`fe_modulation`.
+
+Most of the digital TV standards offers more than one possible
+modulation type.
+
+The table below presents a summary of the types of modulation types
+supported by each delivery system, as currently defined by specs.
+
+======================= =======================================================
+Standard		Modulation types
+======================= =======================================================
+ATSC (version 1)	8-VSB and 16-VSB.
+DMTB			4-QAM, 16-QAM, 32-QAM, 64-QAM and 4-QAM-NR.
+DVB-C Annex A/C		16-QAM, 32-QAM, 64-QAM and 256-QAM.
+DVB-C Annex B		64-QAM.
+DVB-T			QPSK, 16-QAM and 64-QAM.
+DVB-T2			QPSK, 16-QAM, 64-QAM and 256-QAM.
+DVB-S			No need to set. It supports only QPSK.
+DVB-S2			QPSK, 8-PSK, 16-APSK and 32-APSK.
+ISDB-T			QPSK, DQPSK, 16-QAM and 64-QAM.
+ISDB-S			8-PSK, QPSK and BPSK.
+======================= =======================================================
+
+.. note::
+
+   Please notice that some of the above modulation types may not be
+   defined currently at the Kernel. The reason is simple: no driver
+   needed such definition yet.
+
+
+.. _DTV-BANDWIDTH-HZ:
+
+DTV_BANDWIDTH_HZ
+================
+
+Bandwidth for the channel, in HZ.
+
+Should be set only for terrestrial delivery systems.
+
+Possible values: ``1712000``, ``5000000``, ``6000000``, ``7000000``,
+``8000000``, ``10000000``.
+
+======================= =======================================================
+Terrestrial Standard	Possible values for bandwidth
+======================= =======================================================
+ATSC (version 1)	No need to set. It is always 6MHz.
+DMTB			No need to set. It is always 8MHz.
+DVB-T			6MHz, 7MHz and 8MHz.
+DVB-T2			1.172 MHz, 5MHz, 6MHz, 7MHz, 8MHz and 10MHz
+ISDB-T			5MHz, 6MHz, 7MHz and 8MHz, although most places
+			use 6MHz.
+======================= =======================================================
+
+
+.. note::
+
+
+  #. For ISDB-Tsb, the bandwidth can vary depending on the number of
+     connected segments.
+
+     It can be easily derived from other parameters
+     (DTV_ISDBT_SB_SEGMENT_IDX, DTV_ISDBT_SB_SEGMENT_COUNT).
+
+  #. On Satellite and Cable delivery systems, the bandwidth depends on
+     the symbol rate. So, the Kernel will silently ignore any setting
+     :ref:`DTV-BANDWIDTH-HZ`. I will however fill it back with a
+     bandwidth estimation.
+
+     Such bandwidth estimation takes into account the symbol rate set with
+     :ref:`DTV-SYMBOL-RATE`, and the rolloff factor, with is fixed for
+     DVB-C and DVB-S.
+
+     For DVB-S2, the rolloff should also be set via :ref:`DTV-ROLLOFF`.
+
+
+.. _DTV-INVERSION:
+
+DTV_INVERSION
+=============
+
+Specifies if the frontend should do spectral inversion or not.
+
+The acceptable values are defined by :c:type:`fe_spectral_inversion`.
+

+Used on cable and satellite delivery systems.
+
+The acceptable values are defined by :c:type:`fe_code_rate`.
+
+
+.. _DTV-VOLTAGE:
+
+DTV_VOLTAGE
+===========
+
+Used on satellite delivery systems.
+
+The voltage is usually used with non-DiSEqC capable LNBs to switch the
+polarzation (horizontal/vertical). When using DiSEqC epuipment this
+voltage has to be switched consistently to the DiSEqC commands as
+described in the DiSEqC spec.
+
+The acceptable values are defined by :c:type:`fe_sec_voltage`.

+============================
+
+Used only on ISDB.
+
+This field represents whether the other DTV_ISDBT_*-parameters are
+referring to an ISDB-T and an ISDB-Tsb channel. (See also
+``DTV_ISDBT_PARTIAL_RECEPTION``).
+
+Possible values: 0, 1, -1 (AUTO)
+
+
+.. _DTV-ISDBT-SB-SUBCHANNEL-ID:
+
+DTV_ISDBT_SB_SUBCHANNEL_ID
+==========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+(Note of the author: This might not be the correct description of the
+``SUBCHANNEL-ID`` in all details, but it is my understanding of the
+technical background needed to program a device)
+
+An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
+set of connected ISDB-Tsb channels. In this set of channels every
+channel can be received independently. The number of connected ISDB-Tsb
+segment can vary, e.g. depending on the frequency spectrum bandwidth
+available.
+
+Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
+broadcaster has several possibilities to put those channels in the air:
+Assuming a normal 13-segment ISDB-T spectrum he can align the 8 segments
+from position 1-8 to 5-13 or anything in between.
+
+The underlying layer of segments are subchannels: each segment is
+consisting of several subchannels with a predefined IDs. A sub-channel
+is used to help the demodulator to synchronize on the channel.
+
+An ISDB-T channel is always centered over all sub-channels. As for the
+example above, in ISDB-Tsb it is no longer as simple as that.
+
+``The DTV_ISDBT_SB_SUBCHANNEL_ID`` parameter is used to give the
+sub-channel ID of the segment to be demodulated.
+
+Possible values: 0 .. 41, -1 (AUTO)
+
+
+.. _DTV-ISDBT-SB-SEGMENT-IDX:
+
+DTV_ISDBT_SB_SEGMENT_IDX
+========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_IDX`` gives the index of the segment to be
+demodulated for an ISDB-Tsb channel where several of them are
+transmitted in the connected manner.
+
+Possible values: 0 .. ``DTV_ISDBT_SB_SEGMENT_COUNT`` - 1
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _DTV-ISDBT-SB-SEGMENT-COUNT:
+
+DTV_ISDBT_SB_SEGMENT_COUNT
+==========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_COUNT`` gives the total count of connected
+ISDB-Tsb channels.
+
+Possible values: 1 .. 13
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _isdb-hierq-layers:
+
+DTV-ISDBT-LAYER[A-C] parameters
+===============================
+
+Used only on ISDB.
+
+ISDB-T channels can be coded hierarchically. As opposed to DVB-T in
+ISDB-T hierarchical layers can be decoded simultaneously. For that
+reason a ISDB-T demodulator has 3 Viterbi and 3 Reed-Solomon decoders.
+
+ISDB-T has 3 hierarchical layers which each can use a part of the
+available segments. The total number of segments over all layers has to
+13 in ISDB-T.
+
+There are 3 parameter sets, for Layers A, B and C.
+
+
+.. _DTV-ISDBT-LAYER-ENABLED:
+
+DTV_ISDBT_LAYER_ENABLED
+-----------------------
+
+Used only on ISDB.
+
+Hierarchical reception in ISDB-T is achieved by enabling or disabling
+layers in the decoding process. Setting all bits of
+``DTV_ISDBT_LAYER_ENABLED`` to '1' forces all layers (if applicable) to
+be demodulated. This is the default.
+
+If the channel is in the partial reception mode
+(``DTV_ISDBT_PARTIAL_RECEPTION`` = 1) the central segment can be decoded
+independently of the other 12 segments. In that mode layer A has to have
+a ``SEGMENT_COUNT`` of 1.
+
+In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb according
+to ``DTV_ISDBT_PARTIAL_RECEPTION``. ``SEGMENT_COUNT`` must be filled
+accordingly.
+
+Only the values of the first 3 bits are used. Other bits will be silently ignored:
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 0: layer A enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 1: layer B enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 2: layer C enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bits 3-31: unused
+

+
+.. note::
+

+
+   #. If layer B is ``DQPSK`` and ``DTV_ISDBT_PARTIAL_RECEPTION``\ = 0,
+      then layer has to be ``DQPSK``.

+=============
+
+Used on DVB-S2, DVB-T2 and ISDB-S.
+
+DVB-S2, DVB-T2 and ISDB-S support the transmission of several streams on
+a single transport stream. This property enables the digital TV driver to
+handle substream filtering, when supported by the hardware. By default,
+substream filtering is disabled.
+
+For DVB-S2 and DVB-T2, the valid substream id range is from 0 to 255.
+
+For ISDB, the valid substream id range is from 1 to 65535.
+
+To disable it, you should use the special macro NO_STREAM_ID_FILTER.

+.. _DTV-ENUM-DELSYS:
+
+DTV_ENUM_DELSYS
+===============
+
+A Multi standard frontend needs to advertise the delivery systems
+provided. Applications need to enumerate the provided delivery systems,
+before using any other operation with the frontend. Prior to it's
+introduction, FE_GET_INFO was used to determine a frontend type. A
+frontend which provides more than a single delivery system,
+FE_GET_INFO doesn't help much. Applications which intends to use a
+multistandard frontend must enumerate the delivery systems associated
+with it, rather than trying to use FE_GET_INFO. In the case of a
+legacy frontend, the result is just the same as with FE_GET_INFO, but
+in a more structured format
+
+The acceptable values are defined by :c:type:`fe_delivery_system`.

+
+
+.. _DTV-SCRAMBLING-SEQUENCE-INDEX:
+
+DTV_SCRAMBLING_SEQUENCE_INDEX
+=============================
+
+Used on DVB-S2.
+
+This 18 bit field, when present, carries the index of the DVB-S2 physical
+layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
+There is no explicit signalling method to convey scrambling sequence index
+to the receiver. If S2 satellite delivery system descriptor is available
+it can be used to read the scrambling sequence index (EN 300 468 table 41).
+
+By default, gold scrambling sequence index 0 is used.
+
+The valid scrambling sequence index range is from 0 to 262142.

+
+ISDB-T delivery system
+======================
+
+This ISDB-T/ISDB-Tsb API extension should reflect all information needed
+to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
+very sophisticated devices won't need certain parameters to tune.
+
+The information given here should help application writers to know how
+to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.
+
+The details given here about ISDB-T and ISDB-Tsb are just enough to
+basically show the dependencies between the needed parameter values, but
+surely some information is left out. For more detailed information see
+the following documents:
+
+ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
+Broadcasting" and
+
+ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
+Broadcasting".
+
+In order to understand the ISDB specific parameters, one has to have
+some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
+to be known to the reader that an ISDB-T channel consists of 13
+segments, that it can have up to 3 layer sharing those segments, and
+things like that.

+
+******************************
+Frontend statistics indicators
+******************************
+
+The values are returned via ``dtv_property.stat``. If the property is
+supported, ``dtv_property.stat.len`` is bigger than zero.
+
+For most delivery systems, ``dtv_property.stat.len`` will be 1 if the
+stats is supported, and the properties will return a single value for
+each parameter.
+
+It should be noted, however, that new OFDM delivery systems like ISDB
+can use different modulation types for each group of carriers. On such
+standards, up to 3 groups of statistics can be provided, and
+``dtv_property.stat.len`` is updated to reflect the "global" metrics,
+plus one metric per each carrier group (called "layer" on ISDB).
+
+So, in order to be consistent with other delivery systems, the first
+value at :c:type:`dtv_property.stat.dtv_stats <dtv_stats>` array refers
+to the global metric. The other elements of the array represent each
+layer, starting from layer A(index 1), layer B (index 2) and so on.
+
+The number of filled elements are stored at ``dtv_property.stat.len``.
+
+Each element of the ``dtv_property.stat.dtv_stats`` array consists on
+two elements:
+
+-  ``svalue`` or ``uvalue``, where ``svalue`` is for signed values of
+   the measure (dB measures) and ``uvalue`` is for unsigned values
+   (counters, relative scale)
+
+-  ``scale`` - Scale for the value. It can be:
+
+   -  ``FE_SCALE_NOT_AVAILABLE`` - The parameter is supported by the
+      frontend, but it was not possible to collect it (could be a
+      transitory or permanent condition)
+
+   -  ``FE_SCALE_DECIBEL`` - parameter is a signed value, measured in
+      1/1000 dB
+
+   -  ``FE_SCALE_RELATIVE`` - parameter is a unsigned value, where 0
+      means 0% and 65535 means 100%.
+
+   -  ``FE_SCALE_COUNTER`` - parameter is a unsigned value that counts
+      the occurrence of an event, like bit error, block error, or lapsed
+      time.
+
+
+.. _DTV-STAT-SIGNAL-STRENGTH:
+
+DTV_STAT_SIGNAL_STRENGTH
+========================
+
+Indicates the signal strength level at the analog part of the tuner or
+of the demod.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - signal strength is in 0.001 dBm units, power
+   measured in miliwatts. This value is generally negative.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for power (actually, 0 to 65535).
+
+
+.. _DTV-STAT-CNR:
+
+DTV_STAT_CNR
+============
+
+Indicates the Signal to Noise ratio for the main carrier.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - Signal/Noise ratio is in 0.001 dB units.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for Signal/Noise (actually, 0 to 65535).
+
+
+.. _DTV-STAT-PRE-ERROR-BIT-COUNT:
+
+DTV_STAT_PRE_ERROR_BIT_COUNT
+============================
+
+Measures the number of bit errors before the forward error correction
+(FEC) on the inner coding block (before Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_PRE_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be
+divided by
+:ref:`DTV_STAT_PRE_TOTAL_BIT_COUNT <DTV-STAT-PRE-TOTAL-BIT-COUNT>`.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_COUNTER`` - Number of error bits counted before the inner
+   coding.
+
+
+.. _DTV-STAT-PRE-TOTAL-BIT-COUNT:
+
+DTV_STAT_PRE_TOTAL_BIT_COUNT
+============================
+
+Measures the amount of bits received before the inner code block, during
+the same period as
+:ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`
+measurement was taken.
+
+It should be noted that this measurement can be smaller than the total
+amount of bits on the transport stream, as the frontend may need to
+manually restart the measurement, losing some data between each
+measurement interval.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_COUNTER`` - Number of bits counted while measuring
+   :ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`.
+
+
+.. _DTV-STAT-POST-ERROR-BIT-COUNT:
+
+DTV_STAT_POST_ERROR_BIT_COUNT
+=============================
+
+Measures the number of bit errors after the forward error correction
+(FEC) done by inner code block (after Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_POST_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be
+divided by
+:ref:`DTV_STAT_POST_TOTAL_BIT_COUNT <DTV-STAT-POST-TOTAL-BIT-COUNT>`.

+
+DTV_STAT_ERROR_BLOCK_COUNT
+==========================
+
+Measures the number of block errors after the outer forward error
+correction coding (after Reed-Solomon or other outer code).
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+

+Digital TV Frontend API
+#######################
+
+The Digital TV frontend API was designed to support three groups of delivery
+systems: Terrestrial, cable and Satellite. Currently, the following
+delivery systems are supported:
+
+-  Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
+   DTMB, CMMB
+
+-  Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B)
+
+-  Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
+
+The Digital TV frontend controls several sub-devices including:
+
+-  Tuner
+
+-  Digital TV demodulator
+
+-  Low noise amplifier (LNA)
+
+-  Satellite Equipment Control (SEC) [#f1]_.
+
+The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
+Data types and ioctl definitions can be accessed by including
+``linux/dvb/frontend.h`` in your application.
+
+.. note::
+
+   Transmission via the internet (DVB-IP) and MMT (MPEG Media Transport)
+   is not yet handled by this API but a future extension is possible.
+
+.. [#f1]
+
+   On Satellite systems, the API support for the Satellite Equipment
+   Control (SEC) allows to power control and to send/receive signals to
+   control the antenna subsystem, selecting the polarization and choosing
+   the Intermediate Frequency IF) of the Low Noise Block Converter Feed
+   Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
+   (digital SEC) specification is available at
+   `Eutelsat <http://www.eutelsat.com/satellites/4_5_5.html>`__.

+
+
+Description
+===========
+
+This system call opens a named frontend device
+(``/dev/dvb/adapter?/frontend?``) for subsequent use. Usually the first
+thing to do after a successful open is to find out the frontend type
+with :ref:`FE_GET_INFO`.
+
+The device can be opened in read-only mode, which only allows monitoring
+of device status and statistics, or read/write mode, which allows any
+kind of use (e.g. performing tuning operations.)
+
+In a system with multiple front-ends, it is usually the case that
+multiple devices cannot be open in read/write mode simultaneously. As
+long as a front-end device is opened in read/write mode, other open()
+calls in read/write mode will either fail or block, depending on whether
+non-blocking or blocking mode was specified. A front-end device opened
+in blocking mode can later be put into non-blocking mode (and vice
+versa) using the F_SETFL command of the fcntl system call. This is a
+standard system call, documented in the Linux manual page for fcntl.
+When an open() call has succeeded, the device will be ready for use in
+the specified mode. This implies that the corresponding hardware is
+powered up, and that other front-ends may have been powered down to make
+that possible.
+
+
+Return Value
+============
+
+On success :ref:`open() <frontend_f_open>` returns the new file descriptor.
+On error, -1 is returned, and the ``errno`` variable is set appropriately.
+
+Possible error codes are:
+
+
+On success 0 is returned, and :c:type:`ca_slot_info` is filled.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.

+
+
+.. _requisites:
+
+What you need to know
+=====================
+
+The reader of this document is required to have some knowledge in the
+area of digital video broadcasting (Digital TV) and should be familiar with
+part I of the MPEG2 specification ISO/IEC 13818 (aka ITU-T H.222), i.e
+you should know what a program/transport stream (PS/TS) is and what is
+meant by a packetized elementary stream (PES) or an I-frame.
+
+Various Digital TV standards documents are available for download at:
+
+- European standards (DVB): http://www.dvb.org and/or http://www.etsi.org.
+- American standards (ATSC): https://www.atsc.org/standards/
+- Japanese standards (ISDB): http://www.dibeg.org/
+
+It is also necessary to know how to access Linux devices and how to
+use ioctl calls. This also includes the knowledge of C or C++.
+
+
+.. _history:
+
+History
+=======
+
+The first API for Digital TV cards we used at Convergence in late 1999 was an
+extension of the Video4Linux API which was primarily developed for frame
+grabber cards. As such it was not really well suited to be used for Digital
+TV cards and their new features like recording MPEG streams and filtering
+several section and PES data streams at the same time.
+
+In early 2000, Convergence was approached by Nokia with a proposal for a new
+standard Linux Digital TV API. As a commitment to the development of terminals
+based on open standards, Nokia and Convergence made it available to all
+Linux developers and published it on https://linuxtv.org in September
+2000. With the Linux driver for the Siemens/Hauppauge DVB PCI card,
+Convergence provided a first implementation of the Linux Digital TV API.
+Convergence was the maintainer of the Linux Digital TV API in the early
+days.
+
+Now, the API is maintained by the LinuxTV community (i.e. you, the reader
+of this document). The Linux  Digital TV API is constantly reviewed and
+improved together with the improvements at the subsystem's core at the
+Kernel.
+
+
+.. _overview:
+
+Overview
+========
+
+
+.. _stb_components:
+
+.. kernel-figure:: dvbstb.svg
+    :alt:   dvbstb.svg
+    :align: center
+
+    Components of a Digital TV card/STB
+
+A Digital TV card or set-top-box (STB) usually consists of the
+following main hardware components:
+
+Frontend consisting of tuner and digital TV demodulator
+   Here the raw signal reaches the digital TV hardware from a satellite dish or
+   antenna or directly from cable. The frontend down-converts and
+   demodulates this signal into an MPEG transport stream (TS). In case
+   of a satellite frontend, this includes a facility for satellite
+   equipment control (SEC), which allows control of LNB polarization,
+   multi feed switches or dish rotors.
+
+Conditional Access (CA) hardware like CI adapters and smartcard slots
+   The complete TS is passed through the CA hardware. Programs to which
+   the user has access (controlled by the smart card) are decoded in
+   real time and re-inserted into the TS.
+
+   .. note::
+
+      Not every digital TV hardware provides conditional access hardware.
+
+Demultiplexer which filters the incoming Digital TV MPEG-TS stream
+   The demultiplexer splits the TS into its components like audio and
+   video streams. Besides usually several of such audio and video
+   streams it also contains data streams with information about the
+   programs offered in this or other streams of the same provider.
+
+Audio and video decoder
+   The main targets of the demultiplexer are audio and video
+   decoders. After decoding, they pass on the uncompressed audio and
+   video to the computer screen or to a TV set.
+
+   .. note::
+
+      Modern hardware usually doesn't have a separate decoder hardware, as
+      such functionality can be provided by the main CPU, by the graphics
+      adapter of the system or by a signal processing hardware embedded on
+      a Systems on a Chip (SoC) integrated circuit.
+
+      It may also not be needed for certain usages (e.g. for data-only
+      uses like “internet over satellite”).
+
+:ref:`stb_components` shows a crude schematic of the control and data
+flow between those components.
+
+
+
+.. _dvb_devices:
+
+Linux Digital TV Devices
+========================
+
+The Linux Digital TV API lets you control these hardware components through
+currently six Unix-style character devices for video, audio, frontend,
+demux, CA and IP-over-DVB networking. The video and audio devices
+control the MPEG2 decoder hardware, the frontend device the tuner and
+the Digital TV demodulator. The demux device gives you control over the PES
+and section filters of the hardware. If the hardware does not support
+filtering these filters can be implemented in software. Finally, the CA
+device controls all the conditional access capabilities of the hardware.
+It can depend on the individual security requirements of the platform,
+if and how many of the CA functions are made available to the
+application through this device.
+
+All devices can be found in the ``/dev`` tree under ``/dev/dvb``. The
+individual devices are called:
+
+-  ``/dev/dvb/adapterN/audioM``,
+
+-  ``/dev/dvb/adapterN/videoM``,
+
+-  ``/dev/dvb/adapterN/frontendM``,
+
+-  ``/dev/dvb/adapterN/netM``,
+
+-  ``/dev/dvb/adapterN/demuxM``,
+
+-  ``/dev/dvb/adapterN/dvrM``,
+
+-  ``/dev/dvb/adapterN/caM``,
+
+where ``N`` enumerates the Digital TV cards in a system starting from 0, and
+``M`` enumerates the devices of each type within each adapter, starting
+from 0, too. We will omit the “``/dev/dvb/adapterN/``\ ” in the further
+discussion of these devices.
+
+More details about the data structures and function calls of all the
+devices are described in the following chapters.
+
+
+.. _include_files:
+
+API include files
+=================
+
+For each of the Digital TV devices a corresponding include file exists. The
+Digital TV API include files should be included in application sources with a
+partial path like:
+
+
+.. code-block:: c
+
+	#include <linux/dvb/ca.h>
+
+	#include <linux/dvb/dmx.h>
+
+	#include <linux/dvb/frontend.h>
+
+	#include <linux/dvb/net.h>
+
+
+To enable applications to support different API version, an additional
+include file ``linux/dvb/version.h`` exists, which defines the constant
+``DVB_API_VERSION``. This document describes ``DVB_API_VERSION 5.10``.

+NET_ADD_IF - Creates a new network interface for a given Packet ID.
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, NET_ADD_IF, struct dvb_net_if *net_if )
+    :name: NET_ADD_IF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <frontend_f_open>`.
+
+``net_if``
+    pointer to struct :c:type:`dvb_net_if`
+
+
+Description
+===========
+
+The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
+contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
+ULE) and the interface number for the new interface to be created. When
+the system call successfully returns, a new virtual network interface is
+created.
+
+The struct :c:type:`dvb_net_if`::ifnum field will be
+filled with the number of the created interface.
+
+Return Value
+============
+
+On success 0 is returned, and :c:type:`ca_slot_info` is filled.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.
+
+The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+
+Description
+===========
+
+The NET_GET_IF ioctl uses the interface number given by the struct
+:c:type:`dvb_net_if`::ifnum field and fills the content of
+struct :c:type:`dvb_net_if` with the packet ID and
+encapsulation type used on such interface. If the interface was not
+created yet with :ref:`NET_ADD_IF <net>`, it will return -1 and fill

+Digital TV Network API
+######################
+
+The Digital TV net device controls the mapping of data packages that are part
+of a transport stream to be mapped into a virtual network interface,
+visible through the standard Linux network protocol stack.
+
+Currently, two encapsulations are supported:
+
+-  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
+
+-  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
+
+In order to create the Linux virtual network interfaces, an application
+needs to tell to the Kernel what are the PIDs and the encapsulation
+types that are present on the transport stream. This is done through
+``/dev/dvb/adapter?/net?`` device node. The data will be available via
+virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
+the standard ip tools (like ip, route, netstat, ifconfig, etc).
+
+Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
+header.

+-----------
+
+This system call opens a named video device (e.g.

+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the Video Device in O_RDWR mode. All other attempts to
+open the device in this mode will fail, and an error-code will be
+returned. If the Video Device is opened in O_RDONLY mode, the only
+ioctl call that can be used is VIDEO_GET_STATUS. All other call will
+return an error code.

+
+
+Description
+-----------
+
+This ioctl is for Digital TV devices only. To control a V4L2 decoder use the
+V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
+
+This ioctl call suspends the live video stream being played. Decoding
+and playing are frozen. It is then possible to restart the decoding and
+playing process of the video stream using the VIDEO_CONTINUE command.
+If VIDEO_SOURCE_MEMORY is selected in the ioctl call
+VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data
+until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
+
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+
+Description
+-----------
+
+This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
+use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
+
+This ioctl call returns an event of type video_event if available. If
+an event is not available, the behavior depends on whether the device is
+in blocking or non-blocking mode. In the latter case, the call fails
+immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
+blocks until an event becomes available. The standard Linux poll()
+and/or select() system calls can be used with the device file descriptor
+to watch for new events. For select(), the file descriptor should be
+included in the exceptfds argument, and for poll(), POLLPRI should be
+specified as the wake-up condition. Read-only permissions are sufficient
+for this ioctl call.

+
+       -  Indicates which source shall be used for the Video stream.
+
+
+Description
+-----------
+
+This ioctl is for Digital TV devices only. This ioctl was also supported by the
+V4L2 ivtv driver, but that has been replaced by the ivtv-specific
+``IVTV_IOC_PASSTHROUGH_MODE`` ioctl.
+
+This ioctl call informs the video device which source shall be used for
+the input data. The possible sources are demux or memory. If memory is
+selected, the data is fed to the video device through the write command.
+
+.. c:type:: video_stream_source_t
+
+.. code-block:: c
+
+	typedef enum {
+		VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
+		VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
+				comes from the user through the write
+				system call */
+	} video_stream_source_t;
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Digital TV Video Device
+#######################
+
+The Digital TV video device controls the MPEG2 video decoder of the Digital
+TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
+types and and ioctl definitions can be accessed by including
+**linux/dvb/video.h** in your application.
+
+Note that the Digital TV video device only controls decoding of the MPEG video
+stream, not its presentation on the TV or computer screen. On PCs this
+is typically handled by an associated video4linux device, e.g.
+**/dev/video**, which allows scaling and defining output windows.
+
+Some Digital TV cards don’t have their own MPEG decoder, which results in the
+omission of the audio and video device as well as the video4linux
+device.
+
+The ioctls that deal with SPUs (sub picture units) and navigation
+packets are only supported on some MPEG decoders made for DVD playback.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+****************
+Video Data Types
+****************
+
+
+.. _video-format-t:
+
+video_format_t
+==============
+
+The ``video_format_t`` data type defined by
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_FORMAT_4_3,     /* Select 4:3 format */
+	VIDEO_FORMAT_16_9,    /* Select 16:9 format. */
+	VIDEO_FORMAT_221_1    /* 2.21:1 */
+    } video_format_t;
+
+is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
+aspect ratio the output hardware (e.g. TV) has. It is also used in the
+data structures video_status (??) returned by VIDEO_GET_STATUS (??)
+and video_event (??) returned by VIDEO_GET_EVENT (??) which report
+about the display format of the current video stream.
+
+
+.. _video-displayformat-t:
+
+video_displayformat_t
+=====================
+
+In case the display format of the video stream and of the display
+hardware differ the application has to specify how to handle the
+cropping of the picture. This can be done using the
+VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_PAN_SCAN,       /* use pan and scan format */
+	VIDEO_LETTER_BOX,     /* use letterbox format */
+	VIDEO_CENTER_CUT_OUT  /* use center cut out format */
+    } video_displayformat_t;
+
+as argument.
+
+
+.. _video-stream-source-t:
+
+video_stream_source_t
+=====================
+
+The video stream source is set through the VIDEO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demuxer) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
+	VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
+		       comes from the user through the write
+		       system call */
+    } video_stream_source_t;
+
+VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+VIDEO_SOURCE_MEMORY is selected the stream comes from the application
+through the **write()** system call.
+
+
+.. _video-play-state-t:
+
+video_play_state_t
+==================
+
+The following values can be returned by the VIDEO_GET_STATUS call
+representing the state of video playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_STOPPED, /* Video is stopped */
+	VIDEO_PLAYING, /* Video is currently playing */
+	VIDEO_FREEZED  /* Video is freezed */
+    } video_play_state_t;
+
+
+.. c:type:: video_command
+
+struct video_command
+====================
+
+The structure must be zeroed before use by the application This ensures
+it can be extended safely in the future.
+
+
+.. code-block:: c
+
+    struct video_command {
+	__u32 cmd;
+	__u32 flags;
+	union {
+	    struct {
+		__u64 pts;
+	    } stop;
+
+	    struct {
+		/* 0 or 1000 specifies normal speed,
+		   1 specifies forward single stepping,
+		   -1 specifies backward single stepping,
+		   >>1: playback at speed/1000 of the normal speed,
+		   <-1: reverse playback at (-speed/1000) of the normal speed. */
+		__s32 speed;
+		__u32 format;
+	    } play;
+
+	    struct {
+		__u32 data[16];
+	    } raw;
+	};
+    };
+
+
+.. _video-size-t:
+
+video_size_t
+============
+
+
+.. code-block:: c
+
+    typedef struct {
+	int w;
+	int h;
+	video_format_t aspect_ratio;
+    } video_size_t;
+
+
+.. c:type:: video_event
+
+struct video_event
+==================
+
+The following is the structure of a video event as it is returned by the
+VIDEO_GET_EVENT call.
+
+
+.. code-block:: c
+
+    struct video_event {
+	__s32 type;
+    #define VIDEO_EVENT_SIZE_CHANGED    1
+    #define VIDEO_EVENT_FRAME_RATE_CHANGED  2
+    #define VIDEO_EVENT_DECODER_STOPPED     3
+    #define VIDEO_EVENT_VSYNC       4
+	long timestamp;
+	union {
+	    video_size_t size;
+	    unsigned int frame_rate;    /* in frames per 1000sec */
+	    unsigned char vsync_field;  /* unknown/odd/even/progressive */
+	} u;
+    };
+
+
+.. c:type:: video_status
+
+struct video_status
+===================
+
+The VIDEO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+    struct video_status {
+	int                   video_blank;   /* blank video on freeze? */
+	video_play_state_t    play_state;    /* current state of playback */
+	video_stream_source_t stream_source; /* current source (demux/memory) */
+	video_format_t        video_format;  /* current aspect ratio of stream */
+	video_displayformat_t display_format;/* selected cropping mode */
+    };
+
+If video_blank is set video will be blanked out if the channel is
+changed or if playback is stopped. Otherwise, the last picture will be
+displayed. play_state indicates if the video is currently frozen,
+stopped, or being played back. The stream_source corresponds to the
+selected source for the video stream. It can come either from the
+demultiplexer or from memory. The video_format indicates the aspect
+ratio (one of 4:3 or 16:9) of the currently played video stream.
+Finally, display_format corresponds to the selected cropping mode in
+case the source video format is not the same as the format of the output
+device.
+
+
+.. c:type:: video_still_picture
+
+struct video_still_picture
+==========================
+
+An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
+within the following structure.
+
+
+.. code-block:: c
+
+    /* pointer to and size of a single iframe in memory */
+    struct video_still_picture {
+	char *iFrame;        /* pointer to a single iframe in memory */
+	int32_t size;
+    };
+
+
+.. _video_caps:
+
+video capabilities
+==================
+
+A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c
+
+     /* bit definitions for capabilities: */
+     /* can the hardware decode MPEG1 and/or MPEG2? */
+     #define VIDEO_CAP_MPEG1   1
+     #define VIDEO_CAP_MPEG2   2
+     /* can you send a system and/or program stream to video device?
+	(you still have to open the video and the audio device but only
+	 send the stream to the video device) */
+     #define VIDEO_CAP_SYS     4
+     #define VIDEO_CAP_PROG    8
+     /* can the driver also handle SPU, NAVI and CSS encoded data?
+	(CSS API is not present yet) */
+     #define VIDEO_CAP_SPU    16
+     #define VIDEO_CAP_NAVI   32
+     #define VIDEO_CAP_CSS    64

+GNU Free Documentation License
+******************************
+
+
+.. _fdl-preamble:
+
+0. PREAMBLE
+===========
+
+The purpose of this License is to make a manual, textbook, or other
+written document “free” in the sense of freedom: to assure everyone the
+effective freedom to copy and redistribute it, with or without modifying
+it, either commercially or noncommercially. Secondarily, this License
+preserves for the author and publisher a way to get credit for their
+work, while not being considered responsible for modifications made by
+others.
+
+This License is a kind of “copyleft”, which means that derivative works
+of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft license
+designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free program
+should come with manuals providing the same freedoms that the software
+does. But this License is not limited to software manuals; it can be
+used for any textual work, regardless of subject matter or whether it is
+published as a printed book. We recommend this License principally for
+works whose purpose is instruction or reference.
+
+
+.. _fdl-section1:
+
+1. APPLICABILITY AND DEFINITIONS
+================================
+
+
+.. _fdl-document:
+
+This License applies to any manual or other work that contains a notice
+placed by the copyright holder saying it can be distributed under the
+terms of this License. The “Document”, below, refers to any such manual
+or work. Any member of the public is a licensee, and is addressed as
+“you”.
+
+
+.. _fdl-modified:
+
+A “Modified Version” of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+.. _fdl-secondary:
+
+A “Secondary Section” is a named appendix or a front-matter section of
+the :ref:`Document <fdl-document>` that deals exclusively with the
+relationship of the publishers or authors of the Document to the
+Document's overall subject (or to related matters) and contains nothing
+that could fall directly within that overall subject. (For example, if
+the Document is in part a textbook of mathematics, a Secondary Section
+may not explain any mathematics.) The relationship could be a matter of
+historical connection with the subject or with related matters, or of
+legal, commercial, philosophical, ethical or political position
+regarding them.
+
+
+.. _fdl-invariant:
+
+The “Invariant Sections” are certain
+:ref:`Secondary Sections <fdl-secondary>` whose titles are designated,
+as being those of Invariant Sections, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-cover-texts:
+
+The “Cover Texts” are certain short passages of text that are listed, as
+Front-Cover Texts or Back-Cover Texts, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-transparent:
+
+A “Transparent” copy of the :ref:`Document <fdl-document>` means a
+machine-readable copy, represented in a format whose specification is
+available to the general public, whose contents can be viewed and edited
+directly and straightforwardly with generic text editors or (for images
+composed of pixels) generic paint programs or (for drawings) some widely
+available drawing editor, and that is suitable for input to text
+formatters or for automatic translation to a variety of formats suitable
+for input to text formatters. A copy made in an otherwise Transparent
+file format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent. A copy that is
+not “Transparent” is called “Opaque”.
+
+Examples of suitable formats for Transparent copies include plain ASCII
+without markup, Texinfo input format, LaTeX input format, SGML or XML
+using a publicly available DTD, and standard-conforming simple HTML
+designed for human modification. Opaque formats include PostScript, PDF,
+proprietary formats that can be read and edited only by proprietary word
+processors, SGML or XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML produced by some
+word processors for output purposes only.
+
+
+.. _fdl-title-page:
+
+The “Title Page” means, for a printed book, the title page itself, plus
+such following pages as are needed to hold, legibly, the material this
+License requires to appear in the title page. For works in formats which
+do not have any title page as such, “Title Page” means the text near the
+most prominent appearance of the work's title, preceding the beginning
+of the body of the text.
+
+
+.. _fdl-section2:
+
+2. VERBATIM COPYING
+===================
+
+You may copy and distribute the :ref:`Document <fdl-document>` in any
+medium, either commercially or noncommercially, provided that this
+License, the copyright notices, and the license notice saying this
+License applies to the Document are reproduced in all copies, and that
+you add no other conditions whatsoever to those of this License. You may
+not use technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in
+:ref:`section 3 <fdl-section3>`.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+.. _fdl-section3:
+
+3. COPYING IN QUANTITY
+======================
+
+If you publish printed copies of the :ref:`Document <fdl-document>`
+numbering more than 100, and the Document's license notice requires
+:ref:`Cover Texts <fdl-cover-texts>`, you must enclose the copies in
+covers that carry, clearly and legibly, all these Cover Texts:
+Front-Cover Texts on the front cover, and Back-Cover Texts on the back
+cover. Both covers must also clearly and legibly identify you as the
+publisher of these copies. The front cover must present the full title
+with all words of the title equally prominent and visible. You may add
+other material on the covers in addition. Copying with changes limited
+to the covers, as long as they preserve the title of the
+:ref:`Document <fdl-document>` and satisfy these conditions, can be
+treated as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute :ref:`Opaque <fdl-transparent>` copies of
+the :ref:`Document <fdl-document>` numbering more than 100, you must
+either include a machine-readable :ref:`Transparent <fdl-transparent>`
+copy along with each Opaque copy, or state in or with each Opaque copy a
+publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols. If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+:ref:`Document <fdl-document>` well before redistributing any large
+number of copies, to give them a chance to provide you with an updated
+version of the Document.
+
+
+.. _fdl-section4:
+
+4. MODIFICATIONS
+================
+
+You may copy and distribute a :ref:`Modified Version <fdl-modified>`
+of the :ref:`Document <fdl-document>` under the conditions of sections
+:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` above, provided
+that you release the Modified Version under precisely this License, with
+the Modified Version filling the role of the Document, thus licensing
+distribution and modification of the Modified Version to whoever
+possesses a copy of it. In addition, you must do these things in the
+Modified Version:
+
+-  **A.**
+   Use in the :ref:`Title Page <fdl-title-page>` (and on the covers,
+   if any) a title distinct from that of the
+   :ref:`Document <fdl-document>`, and from those of previous versions
+   (which should, if there were any, be listed in the History section of
+   the Document). You may use the same title as a previous version if
+   the original publisher of that version gives permission.
+
+-  **B.**
+   List on the :ref:`Title Page <fdl-title-page>`, as authors, one or
+   more persons or entities responsible for authorship of the
+   modifications in the :ref:`Modified Version <fdl-modified>`,
+   together with at least five of the principal authors of the
+   :ref:`Document <fdl-document>` (all of its principal authors, if it
+   has less than five).
+
+-  **C.**
+   State on the :ref:`Title Page <fdl-title-page>` the name of the
+   publisher of the :ref:`Modified Version <fdl-modified>`, as the
+   publisher.
+
+-  **D.**
+   Preserve all the copyright notices of the
+   :ref:`Document <fdl-document>`.
+
+-  **E.**
+   Add an appropriate copyright notice for your modifications adjacent
+   to the other copyright notices.
+
+-  **F.**
+   Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the
+   :ref:`Modified Version <fdl-modified>` under the terms of this
+   License, in the form shown in the Addendum below.
+
+-  **G.**
+   Preserve in that license notice the full lists of
+   :ref:`Invariant Sections <fdl-invariant>` and required
+   :ref:`Cover Texts <fdl-cover-texts>` given in the
+   :ref:`Document's <fdl-document>` license notice.
+
+-  **H.**
+   Include an unaltered copy of this License.
+
+-  **I.**
+   Preserve the section entitled “History”, and its title, and add to it
+   an item stating at least the title, year, new authors, and publisher
+   of the :ref:`Modified Version <fdl-modified>` as given on the
+   :ref:`Title Page <fdl-title-page>`. If there is no section entitled
+   “History” in the :ref:`Document <fdl-document>`, create one stating
+   the title, year, authors, and publisher of the Document as given on
+   its Title Page, then add an item describing the Modified Version as
+   stated in the previous sentence.
+
+-  **J.**
+   Preserve the network location, if any, given in the
+   :ref:`Document <fdl-document>` for public access to a
+   :ref:`Transparent <fdl-transparent>` copy of the Document, and
+   likewise the network locations given in the Document for previous
+   versions it was based on. These may be placed in the “History”
+   section. You may omit a network location for a work that was
+   published at least four years before the Document itself, or if the
+   original publisher of the version it refers to gives permission.
+
+-  **K.**
+   In any section entitled “Acknowledgements” or “Dedications”, preserve
+   the section's title, and preserve in the section all the substance
+   and tone of each of the contributor acknowledgements and/or
+   dedications given therein.
+
+-  **L.**
+   Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the
+   :ref:`Document <fdl-document>`, unaltered in their text and in
+   their titles. Section numbers or the equivalent are not considered
+   part of the section titles.
+
+-  **M.**
+   Delete any section entitled “Endorsements”. Such a section may not be
+   included in the :ref:`Modified Version <fdl-modified>`.
+
+-  **N.**
+   Do not retitle any existing section as “Endorsements” or to conflict
+   in title with any :ref:`Invariant Section <fdl-invariant>`.
+
+If the :ref:`Modified Version <fdl-modified>` includes new
+front-matter sections or appendices that qualify as
+:ref:`Secondary Sections <fdl-secondary>` and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the list
+of :ref:`Invariant Sections <fdl-invariant>` in the Modified Version's
+license notice. These titles must be distinct from any other section
+titles.
+
+You may add a section entitled “Endorsements”, provided it contains
+nothing but endorsements of your
+:ref:`Modified Version <fdl-modified>` by various parties--for
+example, statements of peer review or that the text has been approved by
+an organization as the authoritative definition of a standard.
+
+You may add a passage of up to five words as a
+:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25
+words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the
+list of :ref:`Cover Texts <fdl-cover-texts>` in the
+:ref:`Modified Version <fdl-modified>`. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or through
+arrangements made by) any one entity. If the
+:ref:`Document <fdl-document>` already includes a cover text for the
+same cover, previously added by you or by arrangement made by the same
+entity you are acting on behalf of, you may not add another; but you may
+replace the old one, on explicit permission from the previous publisher
+that added the old one.
+
+The author(s) and publisher(s) of the :ref:`Document <fdl-document>`
+do not by this License give permission to use their names for publicity
+for or to assert or imply endorsement of any
+:ref:`Modified Version <fdl-modified>`.
+
+
+.. _fdl-section5:
+
+5. COMBINING DOCUMENTS
+======================
+
+You may combine the :ref:`Document <fdl-document>` with other
+documents released under this License, under the terms defined in
+:ref:`section 4 <fdl-section4>` above for modified versions, provided
+that you include in the combination all of the
+:ref:`Invariant Sections <fdl-invariant>` of all of the original
+documents, unmodified, and list them all as Invariant Sections of your
+combined work in its license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical :ref:`Invariant Sections <fdl-invariant>` may be
+replaced with a single copy. If there are multiple Invariant Sections
+with the same name but different contents, make the title of each such
+section unique by adding at the end of it, in parentheses, the name of
+the original author or publisher of that section if known, or else a
+unique number. Make the same adjustment to the section titles in the
+list of Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled “History” in
+the various original documents, forming one section entitled “History”;
+likewise combine any sections entitled “Acknowledgements”, and any
+sections entitled “Dedications”. You must delete all sections entitled
+“Endorsements.”
+
+
+.. _fdl-section6:
+
+6. COLLECTIONS OF DOCUMENTS
+===========================
+
+You may make a collection consisting of the
+:ref:`Document <fdl-document>` and other documents released under this
+License, and replace the individual copies of this License in the
+various documents with a single copy that is included in the collection,
+provided that you follow the rules of this License for verbatim copying
+of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+.. _fdl-section7:
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+=====================================
+
+A compilation of the :ref:`Document <fdl-document>` or its derivatives
+with other separate and independent documents or works, in or on a
+volume of a storage or distribution medium, does not as a whole count as
+a :ref:`Modified Version <fdl-modified>` of the Document, provided no
+compilation copyright is claimed for the compilation. Such a compilation
+is called an “aggregate”, and this License does not apply to the other
+self-contained works thus compiled with the Document , on account of
+their being thus compiled, if they are not themselves derivative works
+of the Document. If the :ref:`Cover Text <fdl-cover-texts>`
+requirement of :ref:`section 3 <fdl-section3>` is applicable to these
+copies of the Document, then if the Document is less than one quarter of
+the entire aggregate, the Document's Cover Texts may be placed on covers
+that surround only the Document within the aggregate. Otherwise they
+must appear on covers around the whole aggregate.
+
+
+.. _fdl-section8:
+
+8. TRANSLATION
+==============
+
+Translation is considered a kind of modification, so you may distribute
+translations of the :ref:`Document <fdl-document>` under the terms of
+:ref:`section 4 <fdl-section4>`. Replacing
+:ref:`Invariant Sections <fdl-invariant>` with translations requires
+special permission from their copyright holders, but you may include

+
+.. flat-table:: Generic error codes
+    :header-rows:  0
+    :stub-columns: 0
+    :widths: 1 16
+
+
+    -  -  ``EAGAIN`` (aka ``EWOULDBLOCK``)
+
+       -  The ioctl can't be handled because the device is in state where it
+	  can't perform it. This could happen for example in case where
+	  device is sleeping and ioctl is performed to query statistics. It
+	  is also returned when the ioctl would need to wait for an event,
+	  but the device was opened in non-blocking mode.
+
+    -  -  ``EBADF``
+
+       -  The file descriptor is not a valid.
+
+    -  -  ``EBUSY``
+
+       -  The ioctl can't be handled because the device is busy. This is
+	  typically return while device is streaming, and an ioctl tried to
+	  change something that would affect the stream, or would require
+	  the usage of a hardware resource that was already allocated. The
+	  ioctl must not be retried without performing another action to fix
+	  the problem first (typically: stop the stream before retrying).
+
+    -  -  ``EFAULT``
+
+       -  There was a failure while copying data from/to userspace, probably
+	  caused by an invalid pointer reference.
+
+    -  -  ``EINVAL``
+
+       -  One or more of the ioctl parameters are invalid or out of the
+	  allowed range. This is a widely used error code. See the
+	  individual ioctl requests for specific causes.
+
+    -  -  ``ENODEV``
+
+       -  Device not found or was removed.
+
+    -  -  ``ENOMEM``
+
+       -  There's not enough memory to handle the desired operation.
+
+    -  -  ``ENOTTY``
+
+       -  The ioctl is not supported by the driver, actually meaning that
+	  the required functionality is not available, or the file
+	  descriptor is not for a media device.
+
+    -  -  ``ENOSPC``
+
+       -  On USB devices, the stream ioctl's can return this error, meaning
+	  that this request would overcommit the usb bandwidth reserved for
+	  periodic transfers (up to 80% of the USB bandwidth).
+
+    -  -  ``EPERM``
+
+       -  Permission denied. Can be returned if the device needs write
+	  permission, or some special capabilities is needed (e. g. root)
+
+    -  -  ``EIO``
+
+       -  I/O error. Typically used when there are problems communicating with
+          a hardware device. This could indicate broken or flaky hardware.
+	  It's a 'Something is wrong, I give up!' type of error.
+
+    -  - ``ENXIO``
+
+       -  No device corresponding to this device special file exists.
+
+
+.. note::
+
+  #. This list is not exhaustive; ioctls may return other error codes.
+     Since errors may have side effects such as a driver reset,
+     applications should abort on unexpected errors, or otherwise
+     assume that the device is in a bad state.
+
+  #. Request-specific error codes are listed in the individual
+     requests descriptions.

+Introduction
+============
+
+Media devices increasingly handle multiple related functions. Many USB
+cameras include microphones, video capture hardware can also output
+video, or SoC camera interfaces also perform memory-to-memory operations
+similar to video codecs.
+
+Independent functions, even when implemented in the same hardware, can
+be modelled as separate devices. A USB camera with a microphone will be
+presented to userspace applications as V4L2 and ALSA capture devices.
+The devices' relationships (when using a webcam, end-users shouldn't
+have to manually select the associated USB microphone), while not made
+available directly to applications by the drivers, can usually be
+retrieved from sysfs.
+
+With more and more advanced SoC devices being introduced, the current
+approach will not scale. Device topologies are getting increasingly
+complex and can't always be represented by a tree structure. Hardware
+blocks are shared between different functions, creating dependencies
+between seemingly unrelated devices.
+
+Kernel abstraction APIs such as V4L2 and ALSA provide means for
+applications to access hardware parameters. As newer hardware expose an
+increasingly high number of those parameters, drivers need to guess what
+applications really require based on limited information, thereby
+implementing policies that belong to userspace.
+
+The media controller API aims at solving those problems.

+
+Media device model
+==================
+
+Discovering a device internal topology, and configuring it at runtime,
+is one of the goals of the media controller API. To achieve this,
+hardware devices and Linux Kernel interfaces are modelled as graph
+objects on an oriented graph. The object types that constitute the graph
+are:
+
+-  An **entity** is a basic media hardware or software building block.
+   It can correspond to a large variety of logical blocks such as
+   physical hardware devices (CMOS sensor for instance), logical
+   hardware devices (a building block in a System-on-Chip image
+   processing pipeline), DMA channels or physical connectors.
+
+-  An **interface** is a graph representation of a Linux Kernel
+   userspace API interface, like a device node or a sysfs file that
+   controls one or more entities in the graph.
+
+-  A **pad** is a data connection endpoint through which an entity can
+   interact with other entities. Data (not restricted to video) produced
+   by an entity flows from the entity's output to one or more entity
+   inputs. Pads should not be confused with physical pins at chip
+   boundaries.
+
+-  A **data link** is a point-to-point oriented connection between two
+   pads, either on the same entity or on different entities. Data flows
+   from a source pad to a sink pad.
+
+-  An **interface link** is a point-to-point bidirectional control
+   connection between a Linux Kernel interface and an entity.

+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :ref:`ioctl() <media-func-ioctl>` function manipulates media device
+parameters. The argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the media function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying media ioctl requests and
+their parameters are located in the media.h header file. All media ioctl
+requests, their respective function and parameters are specified in
+:ref:`media-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+    Other flags have no effect.
+
+
+Description
+===========
+
+To open a media device applications call :ref:`open() <media-func-open>` with the

+
+
+Return Value
+============
+
+:ref:`open() <func-open>` returns the new file descriptor on success. On error,
+-1 is returned, and ``errno`` is set appropriately. Possible error codes
+are:
+
+EACCES
+    The requested access to the file is not allowed.
+
+EMFILE
+    The process already has the maximum number of files open.
+
+ENFILE
+    The system limit on the total number of open files has been reached.
+
+ENOMEM
+    Insufficient kernel memory was available.
+
+ENXIO
+    No device corresponding to this device special file exists.

+
+Description
+===========
+
+All media devices must support the ``MEDIA_IOC_DEVICE_INFO`` ioctl. To
+query device information, applications call the ioctl with a pointer to
+a struct :c:type:`media_device_info`. The driver
+fills the structure and returns the information to the application. The
+ioctl never fails.

+	  ASCII string. The driver version is stored in the

+
+	  Driver specific applications can use this information to verify
+	  the driver identity. It is also useful to work around known bugs,
+	  or to identify drivers in error reports.

+
+    *  -  __u32
+       -  ``driver_version``

+       -  ``reserved``\ [31]
+       -  Reserved for future extensions. Drivers and applications must set
+	  this array to zero.
+
+
+The ``serial`` and ``bus_info`` fields can be used to distinguish
+between multiple instances of otherwise identical hardware. The serial
+number takes precedence when provided and can be assumed to be unique.
+If the serial number is an empty string, the ``bus_info`` field can be
+used instead. The ``bus_info`` field is guaranteed to be unique, but can
+vary across reboots or device unplug/replug.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+MEDIA_IOC_ENUM_LINKS ioctl with a pointer to this structure.
+
+If the ``pads`` field is not NULL, the driver fills the ``pads`` array
+with information about the entity's pads. The array must have enough
+room to store all the entity's pads. The number of pads can be retrieved
+with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+If the ``links`` field is not NULL, the driver fills the ``links`` array
+with information about the entity's outbound links. The array must have
+enough room to store all the entity's outbound links. The number of
+outbound links can be retrieved with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+Only forward links that originate at one of the entity's source pads are

+    :name: MEDIA_IOC_REQUEST_ALLOC
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <media-func-open>`.
+
+``argp``
+    Pointer to an integer.
+
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this ioctl can be used to allocate a request. If it is not supported, then
+``errno`` is set to ``ENOTTY``. A request is accessed through a file descriptor
+that is returned in ``*argp``.
+
+If the request was successfully allocated, then the request file descriptor
+can be passed to the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctls.
+
+In addition, the request can be queued by calling
+:ref:`MEDIA_REQUEST_IOC_QUEUE` and re-initialized by calling
+:ref:`MEDIA_REQUEST_IOC_REINIT`.
+
+Finally, the file descriptor can be :ref:`polled <request-func-poll>` to wait
+for the request to complete.
+
+The request will remain allocated until all the file descriptors associated
+with it are closed by :ref:`close() <request-func-close>` and the driver no
+longer uses the request internally. See also
+:ref:`here <media-request-life-time>` for more information.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENOTTY
+    The driver has no support for requests.

+MEDIA_IOC_SETUP_LINK - Modify the properties of a link
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, MEDIA_IOC_SETUP_LINK, struct media_link_desc *argp )
+    :name: MEDIA_IOC_SETUP_LINK
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <media-func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`media_link_desc`.
+
+
+Description
+===========
+
+To change link properties applications fill a struct
+:c:type:`media_link_desc` with link identification
+information (source and sink pad) and the new requested link flags. They
+then call the MEDIA_IOC_SETUP_LINK ioctl with a pointer to that
+structure.
+
+The only configurable property is the ``ENABLED`` link flag to
+enable/disable a link. Links marked with the ``IMMUTABLE`` link flag can
+not be enabled or disabled.
+
+Link configuration has no side effect on other links. If an enabled link
+at the sink pad prevents the link from being enabled, the driver returns
+with an ``EBUSY`` error code.
+
+Only links marked with the ``DYNAMIC`` link flag can be enabled/disabled
+while streaming media data. Attempting to enable or disable a streaming
+non-dynamic link will return an ``EBUSY`` error code.
+
+If the specified link can't be found the driver returns with an ``EINVAL``
+error code.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    The struct :c:type:`media_link_desc` references a
+    non-existing link, or the link is immutable and an attempt to modify
+    its configuration was made.

+MEDIA_REQUEST_IOC_QUEUE - Queue a request
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int request_fd, MEDIA_REQUEST_IOC_QUEUE )
+    :name: MEDIA_REQUEST_IOC_QUEUE
+
+
+Arguments
+=========
+
+``request_fd``
+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this request ioctl can be used to queue a previously allocated request.
+
+If the request was successfully queued, then the file descriptor can be
+:ref:`polled <request-func-poll>` to wait for the request to complete.
+
+If the request was already queued before, then ``EBUSY`` is returned.
+Other errors can be returned if the contents of the request contained
+invalid or inconsistent data, see the next section for a list of
+common error codes. On error both the request and driver state are unchanged.
+
+Once a request is queued, then the driver is required to gracefully handle
+errors that occur when the request is applied to the hardware. The
+exception is the ``EIO`` error which signals a fatal error that requires
+the application to stop streaming to reset the hardware state.
+
+It is not allowed to mix queuing requests with queuing buffers directly
+(without a request). ``EBUSY`` will be returned if the first buffer was
+queued directly and you next try to queue a request, or vice versa.
+
+A request must contain at least one buffer, otherwise this ioctl will
+return an ``ENOENT`` error.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EBUSY
+    The request was already queued or the application queued the first
+    buffer directly, but later attempted to use a request. It is not permitted
+    to mix the two APIs.
+ENOENT
+    The request did not contain any buffers. All requests are required
+    to have at least one buffer. This can also be returned if some required
+    configuration is missing in the request.
+ENOMEM
+    Out of memory when allocating internal data structures for this
+    request.
+EINVAL
+    The request has invalid data.
+EIO
+    The hardware is in a bad state. To recover, the application needs to
+    stop streaming to reset the hardware state and then try to restart
+    streaming.

+Synopsis
+========
+

+    :name: MEDIA_REQUEST_IOC_REINIT
+
+
+Arguments

+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this request ioctl can be used to re-initialize a previously allocated
+request.
+
+Re-initializing a request will clear any existing data from the request.
+This avoids having to :ref:`close() <request-func-close>` a completed
+request and allocate a new request. Instead the completed request can just
+be re-initialized and it is ready to be used again.
+
+A request can only be re-initialized if it either has not been queued
+yet, or if it was queued and completed. Otherwise it will set ``errno``
+to ``EBUSY``. No other error codes can be returned.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately.
+
+EBUSY
+    The request is queued but not yet completed.

+
+Request API
+===========
+
+The Request API has been designed to allow V4L2 to deal with requirements of
+modern devices (stateless codecs, complex camera pipelines, ...) and APIs
+(Android Codec v2). One such requirement is the ability for devices belonging to
+the same pipeline to reconfigure and collaborate closely on a per-frame basis.
+Another is support of stateless codecs, which require controls to be applied
+to specific frames (aka 'per-frame controls') in order to be used efficiently.
+
+While the initial use-case was V4L2, it can be extended to other subsystems
+as well, as long as they use the media controller.
+
+Supporting these features without the Request API is not always possible and if
+it is, it is terribly inefficient: user-space would have to flush all activity
+on the media pipeline, reconfigure it for the next frame, queue the buffers to
+be processed with that configuration, and wait until they are all available for
+dequeuing before considering the next frame. This defeats the purpose of having
+buffer queues since in practice only one buffer would be queued at a time.
+
+The Request API allows a specific configuration of the pipeline (media
+controller topology + configuration for each media entity) to be associated with
+specific buffers. This allows user-space to schedule several tasks ("requests")
+with different configurations in advance, knowing that the configuration will be
+applied when needed to get the expected result. Configuration values at the time
+of request completion are also available for reading.
+
+General Usage
+-------------
+
+The Request API extends the Media Controller API and cooperates with
+subsystem-specific APIs to support request usage. At the Media Controller
+level, requests are allocated from the supporting Media Controller device
+node. Their life cycle is then managed through the request file descriptors in
+an opaque way. Configuration data, buffer handles and processing results
+stored in requests are accessed through subsystem-specific APIs extended for
+request support, such as V4L2 APIs that take an explicit ``request_fd``
+parameter.
+
+Request Allocation
+------------------
+
+User-space allocates requests using :ref:`MEDIA_IOC_REQUEST_ALLOC`
+for the media device node. This returns a file descriptor representing the
+request. Typically, several such requests will be allocated.
+
+Request Preparation
+-------------------
+
+Standard V4L2 ioctls can then receive a request file descriptor to express the
+fact that the ioctl is part of said request, and is not to be applied
+immediately. See :ref:`MEDIA_IOC_REQUEST_ALLOC` for a list of ioctls that
+support this. Configurations set with a ``request_fd`` parameter are stored
+instead of being immediately applied, and buffers queued to a request do not
+enter the regular buffer queue until the request itself is queued.
+
+Request Submission
+------------------
+
+Once the configuration and buffers of the request are specified, it can be
+queued by calling :ref:`MEDIA_REQUEST_IOC_QUEUE` on the request file descriptor.
+A request must contain at least one buffer, otherwise ``ENOENT`` is returned.
+A queued request cannot be modified anymore.
+
+.. caution::
+   For :ref:`memory-to-memory devices <mem2mem>` you can use requests only for
+   output buffers, not for capture buffers. Attempting to add a capture buffer
+   to a request will result in an ``EBADR`` error.
+
+If the request contains configurations for multiple entities, individual drivers
+may synchronize so the requested pipeline's topology is applied before the
+buffers are processed. Media controller drivers do a best effort implementation
+since perfect atomicity may not be possible due to hardware limitations.
+
+.. caution::
+
+   It is not allowed to mix queuing requests with directly queuing buffers:
+   whichever method is used first locks this in place until
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called or the device is
+   :ref:`closed <func-close>`. Attempts to directly queue a buffer when earlier
+   a buffer was queued via a request or vice versa will result in an ``EBUSY``
+   error.
+
+Controls can still be set without a request and are applied immediately,
+regardless of whether a request is in use or not.
+
+.. caution::
+
+   Setting the same control through a request and also directly can lead to
+   undefined behavior!
+
+User-space can :ref:`poll() <request-func-poll>` a request file descriptor in
+order to wait until the request completes. A request is considered complete
+once all its associated buffers are available for dequeuing and all the
+associated controls have been updated with the values at the time of completion.
+Note that user-space does not need to wait for the request to complete to
+dequeue its buffers: buffers that are available halfway through a request can
+be dequeued independently of the request's state.
+
+A completed request contains the state of the device after the request was
+executed. User-space can query that state by calling
+:ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` with the request file
+descriptor. Calling :ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
+request that has been queued but not yet completed will return ``EBUSY``
+since the control values might be changed at any time by the driver while the
+request is in flight.
+
+.. _media-request-life-time:
+
+Recycling and Destruction
+-------------------------
+
+Finally, a completed request can either be discarded or be reused. Calling
+:ref:`close() <request-func-close>` on a request file descriptor will make
+that file descriptor unusable and the request will be freed once it is no
+longer in use by the kernel. That is, if the request is queued and then the
+file descriptor is closed, then it won't be freed until the driver completed
+the request.
+
+The :ref:`MEDIA_REQUEST_IOC_REINIT` will clear a request's state and make it
+available again. No state is retained by this operation: the request is as
+if it had just been allocated.
+
+Example for a Codec Device
+--------------------------
+
+For use-cases such as :ref:`codecs <mem2mem>`, the request API can be used
+to associate specific controls to
+be applied by the driver for the OUTPUT buffer, allowing user-space
+to queue many such buffers in advance. It can also take advantage of requests'
+ability to capture the state of controls when the request completes to read back
+information that may be subject to change.
+
+Put into code, after obtaining a request, user-space can assign controls and one
+OUTPUT buffer to it:
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+	struct v4l2_ext_controls ctrls;
+	int req_fd;
+	...
+	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
+		return errno;
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
+		return errno;
+	...
+	buf.type = V4L2_BUF_TYPE_VIDEO_OUTPUT;
+	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
+	buf.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_QBUF, &buf))
+		return errno;
+
+Note that it is not allowed to use the Request API for CAPTURE buffers
+since there are no per-frame settings to report there.
+
+Once the request is fully prepared, it can be queued to the driver:
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
+		return errno;
+
+User-space can then either wait for the request to complete by calling poll() on
+its file descriptor, or start dequeuing CAPTURE buffers. Most likely, it will
+want to get CAPTURE buffers as soon as possible and this can be done using a
+regular :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`:
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+
+	memset(&buf, 0, sizeof(buf));
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	if (ioctl(codec_fd, VIDIOC_DQBUF, &buf))
+		return errno;
+
+Note that this example assumes for simplicity that for every OUTPUT buffer
+there will be one CAPTURE buffer, but this does not have to be the case.
+
+We can then, after ensuring that the request is completed via polling the
+request file descriptor, query control values at the time of its completion via
+a call to :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.
+This is particularly useful for volatile controls for which we want to
+query values as soon as the capture buffer is produced.
+
+.. code-block:: c
+
+	struct pollfd pfd = { .events = POLLPRI, .fd = req_fd };
+	poll(&pfd, 1, -1);
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_G_EXT_CTRLS, &ctrls))
+		return errno;
+
+Once we don't need the request anymore, we can either recycle it for reuse with
+:ref:`MEDIA_REQUEST_IOC_REINIT`...
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_REINIT))
+		return errno;
+
+... or close its file descriptor to completely dispose of it.
+
+.. code-block:: c
+
+	close(req_fd);
+
+Example for a Simple Capture Device
+-----------------------------------
+
+With a simple capture device, requests can be used to specify controls to apply
+for a given CAPTURE buffer.
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+	struct v4l2_ext_controls ctrls;
+	int req_fd;
+	...
+	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
+		return errno;
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(camera_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
+		return errno;
+	...
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
+	buf.request_fd = req_fd;
+	if (ioctl(camera_fd, VIDIOC_QBUF, &buf))
+		return errno;
+
+Once the request is fully prepared, it can be queued to the driver:
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
+		return errno;
+
+User-space can then dequeue buffers, wait for the request completion, query
+controls and recycle the request as in the M2M example above.

+
+    #include <sys/ioctl.h>
+
+
+.. c:function:: int ioctl( int fd, int cmd, void *argp )
+    :name: req-ioctl
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+``cmd``
+    The request ioctl command code as defined in the media.h header file, for
+    example :ref:`MEDIA_REQUEST_IOC_QUEUE`.
+
+``argp``
+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :ref:`ioctl() <request-func-ioctl>` function manipulates request
+parameters. The argument ``fd`` must be an open file descriptor.
+
+The ioctl ``cmd`` code specifies the request function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying request ioctl commands and
+their parameters are located in the media.h header file. All request ioctl
+commands, their respective function and parameters are specified in
+:ref:`media-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Command-specific error codes are listed in the individual command
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+request-poll - Wait for some event on a file descriptor
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
+   :name: request-poll
+
+Arguments
+=========
+
+``ufds``
+   List of file descriptor events to be watched
+
+``nfds``
+   Number of file descriptor events at the \*ufds array
+
+``timeout``
+   Timeout to wait for events
+
+
+Description
+===========
+
+With the :c:func:`poll() <request-func-poll>` function applications can wait
+for a request to complete.
+
+On success :c:func:`poll() <request-func-poll>` returns the number of file
+descriptors that have been selected (that is, file descriptors for which the
+``revents`` field of the respective struct :c:type:`pollfd`
+is non-zero). Request file descriptor set the ``POLLPRI`` flag in ``revents``
+when the request was completed.  When the function times out it returns
+a value of zero, on failure it returns -1 and the ``errno`` variable is
+set appropriately.
+
+Attempting to poll for a request that is not yet queued will
+set the ``POLLERR`` flag in ``revents``.
+
+
+Return Value
+============
+
+On success, :c:func:`poll() <request-func-poll>` returns the number of
+structures which have non-zero ``revents`` fields, or zero if the call
+timed out. On error -1 is returned, and the ``errno`` variable is set
+appropriately:
+
+``EBADF``
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+``EFAULT``
+    ``ufds`` references an inaccessible memory area.
+
+``EINTR``
+    The call was interrupted by a signal.
+
+``EINVAL``
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+Introduction
+************
+
+LIRC stands for Linux Infrared Remote Control. The LIRC device interface is
+a bi-directional interface for transporting raw IR and decoded scancodes
+data between userspace and kernelspace. Fundamentally, it is just a chardev
+(/dev/lircX, for X = 0, 1, 2, ...), with a number of standard struct
+file_operations defined on it. With respect to transporting raw IR and
+decoded scancodes to and fro, the essential fops are read, write and ioctl.
+
+It is also possible to attach a BPF program to a LIRC device for decoding
+raw IR into scancodes.
+
+Example dmesg output upon a driver registering w/LIRC:
+
+.. code-block:: none
+
+    $ dmesg |grep lirc_dev
+    rc rc0: lirc_dev: driver mceusb registered at minor = 0, raw IR receiver, raw IR transmitter
+
+What you should see for a chardev:
+
+.. code-block:: none
+
+    $ ls -l /dev/lirc*
+    crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0
+
+Note that the package `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_
+contains tools for working with LIRC devices:
+
+ - ir-ctl: can receive raw IR and transmit IR, as well as query LIRC
+   device features.
+
+ - ir-keytable: can load keymaps; allows you to set IR kernel protocols; load
+   BPF IR decoders and test IR decoding. Some BPF IR decoders are also
+   provided.
+
+.. _lirc_modes:
+
+**********
+LIRC modes
+**********
+
+LIRC supports some modes of receiving and sending IR codes, as shown
+on the following table.
+
+.. _lirc-mode-scancode:
+.. _lirc-scancode-flag-toggle:
+.. _lirc-scancode-flag-repeat:
+
+``LIRC_MODE_SCANCODE``
+
+    This mode is for both sending and receiving IR.
+
+    For transmitting (aka sending), create a ``struct lirc_scancode`` with
+    the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
+    set to the :ref:`IR protocol <Remote_controllers_Protocols>`, and all other
+    members set to 0. Write this struct to the lirc device.
+
+    For receiving, you read ``struct lirc_scancode`` from the LIRC device.
+    The ``scancode`` field is set to the received scancode and the
+    :ref:`IR protocol <Remote_controllers_Protocols>` is set in
+    :c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
+    in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
+
+    The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
+    bit is set in protocols that support it (e.g. rc-5 and rc-6), or
+    ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
+    that support it (e.g. nec).
+
+    In the Sanyo and NEC protocol, if you hold a button on remote, rather than
+    repeating the entire scancode, the remote sends a shorter message with
+    no scancode, which just means button is held, a "repeat". When this is
+    received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
+    keycode is repeated.
+
+    With nec, there is no way to distinguish "button hold" from "repeatedly
+    pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
+    When a button is released and pressed again, the toggle bit is inverted.
+    If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
+
+    The ``timestamp`` field is filled with the time nanoseconds
+    (in ``CLOCK_MONOTONIC``) when the scancode was decoded.
+
+.. _lirc-mode-mode2:
+
+``LIRC_MODE_MODE2``
+
+    The driver returns a sequence of pulse and space codes to userspace,
+    as a series of u32 values.
+
+    This mode is used only for IR receive.
+
+    The upper 8 bits determine the packet type, and the lower 24 bits
+    the payload. Use ``LIRC_VALUE()`` macro to get the payload, and
+    the macro ``LIRC_MODE2()`` will give you the type, which
+    is one of:
+
+    ``LIRC_MODE2_PULSE``
+
+        Signifies the presence of IR in microseconds.
+
+    ``LIRC_MODE2_SPACE``
+
+        Signifies absence of IR in microseconds.
+
+    ``LIRC_MODE2_FREQUENCY``
+
+        If measurement of the carrier frequency was enabled with
+        :ref:`lirc_set_measure_carrier_mode` then this packet gives you
+        the carrier frequency in Hertz.
+
+    ``LIRC_MODE2_TIMEOUT``
+
+        If timeout reports are enabled with
+        :ref:`lirc_set_rec_timeout_reports`, when the timeout set with
+        :ref:`lirc_set_rec_timeout` expires due to no IR being detected,
+        this packet will be sent, with the number of microseconds with
+        no IR.
+
+.. _lirc-mode-pulse:
+
+``LIRC_MODE_PULSE``
+
+    In pulse mode, a sequence of pulse/space integer values are written to the
+    lirc device using :ref:`lirc-write`.
+
+    The values are alternating pulse and space lengths, in microseconds. The
+    first and last entry must be a pulse, so there must be an odd number
+    of entries.
+
+    This mode is used only for IR send.
+
+********************
+BPF based IR decoder
+********************
+
+The kernel has support for decoding the most common
+:ref:`IR protocols <Remote_controllers_Protocols>`, but there
+are many protocols which are not supported. To support these, it is possible
+to load an BPF program which does the decoding. This can only be done on
+LIRC devices which support reading raw IR.
+
+First, using the `bpf(2)`_ syscall with the ``BPF_LOAD_PROG`` argument,
+program must be loaded of type ``BPF_PROG_TYPE_LIRC_MODE2``. Once attached
+to the LIRC device, this program will be called for each pulse, space or
+timeout event on the LIRC device. The context for the BPF program is a
+pointer to a unsigned int, which is a :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`
+value. When the program has decoded the scancode, it can be submitted using
+the BPF functions ``bpf_rc_keydown()`` or ``bpf_rc_repeat()``. Mouse or pointer
+movements can be reported using ``bpf_rc_pointer_rel()``.
+
+Once you have the file descriptor for the ``BPF_PROG_TYPE_LIRC_MODE2`` BPF
+program, it can be attached to the LIRC device using the `bpf(2)`_ syscall.
+The target must be the file descriptor for the LIRC device, and the
+attach type must be ``BPF_LIRC_MODE2``. No more than 64 BPF programs can be
+attached to a single LIRC device at a time.

+lirc-read - Read from a LIRC device
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. c:function:: ssize_t read( int fd, void *buf, size_t count )
+    :name: lirc-read
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+   Buffer to be filled
+
+``count``
+   Max number of bytes to read
+
+Description
+===========
+
+:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``.  If ``count`` is zero,
+:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
+is greater than ``SSIZE_MAX``, the result is unspecified.
+
+The exact format of the data depends on what :ref:`lirc_modes` a driver
+uses. Use :ref:`lirc_get_features` to get the supported mode, and use
+:ref:`lirc_set_rec_mode` set the current active mode.
+
+The mode :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` is for raw IR,
+in which packets containing an unsigned int value describing an IR signal are
+read from the chardev.
+
+Alternatively, :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` can be available,
+in this mode scancodes which are either decoded by software decoders, or
+by hardware decoders. The :c:type:`rc_proto` member is set to the
+:ref:`IR protocol <Remote_controllers_Protocols>`
+used for transmission, and ``scancode`` to the decoded scancode,
+and the ``keycode`` set to the keycode or ``KEY_RESERVED``.
+
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame.  On error, -1 is returned, and the ``errno``
+variable is set appropriately.

+
+
+Description
+===========
+
+Some receivers are equipped with special wide band receiver which is
+intended to be used to learn output of existing remote. This ioctl
+allows enabling or disabling it.
+
+This might be useful of receivers that have otherwise narrow band receiver
+that prevents them to be used with some remotes. Wide band receiver might
+also be more precise. On the other hand its disadvantage it usually
+reduced range of reception.
+
+.. note::
+
+    Wide band receiver might be implictly enabled if you enable
+    carrier reports. In that case it will be disabled as soon as you disable
+    carrier reports. Trying to disable wide band receiver while carrier
+    reports are active will do nothing.

+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+    Buffer with data to be written
+
+``count``
+    Number of bytes at the buffer
+
+Description
+===========
+
+:ref:`write() <lirc-write>` writes up to ``count`` bytes to the device
+referenced by the file descriptor ``fd`` from the buffer starting at
+``buf``.
+
+The exact format of the data depends on what mode a driver is in, use
+:ref:`lirc_get_features` to get the supported modes and use
+:ref:`lirc_set_send_mode` set the mode.
+
+When in :ref:`LIRC_MODE_PULSE <lirc-mode-PULSE>` mode, the data written to
+the chardev is a pulse/space sequence of integer values. Pulses and spaces
+are only marked implicitly by their position. The data must start and end
+with a pulse, therefore, the data must always include an uneven number of
+samples. The write function blocks until the data has been transmitted
+by the hardware. If more data is provided than the hardware can send, the
+driver returns ``EINVAL``.
+
+When in :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` mode, one
+``struct lirc_scancode`` must be written to the chardev at a time, else
+``EINVAL`` is returned. Set the desired scancode in the ``scancode`` member,
+and the :ref:`IR protocol <Remote_controllers_Protocols>` in the
+:c:type:`rc_proto`: member. All other members must be
+set to 0, else ``EINVAL`` is returned. If there is no protocol encoder
+for the protocol or the scancode is not valid for the specified protocol,
+``EINVAL`` is returned. The write function blocks until the scancode
+is transmitted by the hardware.
+
+
+Return Value
+============
+
+On success, the number of bytes written is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame.  On error, -1 is returned, and the ``errno``
+variable is set appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Introduction
+************
+
+Currently, most analog and digital devices have a Infrared input for
+remote controllers. Each manufacturer has their own type of control. It
+is not rare for the same manufacturer to ship different types of
+controls, depending on the device.
+
+A Remote Controller interface is mapped as a normal evdev/input
+interface, just like a keyboard or a mouse. So, it uses all ioctls
+already defined for any other input devices.
+
+However, remove controllers are more flexible than a normal input
+device, as the IR receiver (and/or transmitter) can be used in
+conjunction with a wide variety of different IR remotes.
+
+In order to allow flexibility, the Remote Controller subsystem allows
+controlling the RC-specific attributes via
+:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.

+A ``/sys/class/rc/rcN`` directory is created for each remote control
+receiver device where N is the number of the receiver.
+
+
+.. _sys_class_rc_rcN_protocols:
+
+/sys/class/rc/rcN/protocols
+===========================
+
+Reading this file returns a list of available protocols, something like::
+
+	rc5 [rc6] nec jvc [sony]
+
+Enabled protocols are shown in [] brackets.
+
+Writing "+proto" will add a protocol to the list of enabled protocols.
+
+Writing "-proto" will remove a protocol from the list of enabled
+protocols.
+
+Writing "proto" will enable only "proto".
+
+Writing "none" will disable all protocols.
+
+Write fails with ``EINVAL`` if an invalid protocol combination or unknown
+protocol name is used.
+
+
+.. _sys_class_rc_rcN_filter:
+
+/sys/class/rc/rcN/filter
+========================
+
+Sets the scancode filter expected value.
+
+Use in combination with ``/sys/class/rc/rcN/filter_mask`` to set the
+expected value of the bits set in the filter mask. If the hardware
+supports it then scancodes which do not match the filter will be
+ignored. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the current protocol is altered.
+
+
+.. _sys_class_rc_rcN_filter_mask:
+
+/sys/class/rc/rcN/filter_mask
+=============================
+
+Sets the scancode filter mask of bits to compare. Use in combination
+with ``/sys/class/rc/rcN/filter`` to set the bits of the scancode which
+should be compared against the expected value. A value of 0 disables the
+filter to allow all valid scancodes to be processed.
+
+If the hardware supports it then scancodes which do not match the filter
+will be ignored. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the current protocol is altered.
+
+
+.. _sys_class_rc_rcN_wakeup_protocols:
+
+/sys/class/rc/rcN/wakeup_protocols
+==================================
+
+Reading this file returns a list of available protocols to use for the
+wakeup filter, something like::
+
+	rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce
+
+Note that protocol variants are listed, so ``nec``, ``sony``, ``rc-5``, ``rc-6``
+have their different bit length encodings listed if available.
+
+Note that all protocol variants are listed.
+
+The enabled wakeup protocol is shown in [] brackets.
+
+Only one protocol can be selected at a time.
+
+Writing "proto" will use "proto" for wakeup events.
+
+Writing "none" will disable wakeup.
+
+Write fails with ``EINVAL`` if an invalid protocol combination or unknown
+protocol name is used, or if wakeup is not supported by the hardware.
+
+
+.. _sys_class_rc_rcN_wakeup_filter:
+
+/sys/class/rc/rcN/wakeup_filter
+===============================
+
+Sets the scancode wakeup filter expected value. Use in combination with
+``/sys/class/rc/rcN/wakeup_filter_mask`` to set the expected value of
+the bits set in the wakeup filter mask to trigger a system wake event.
+
+If the hardware supports it and wakeup_filter_mask is not 0 then
+scancodes which match the filter will wake the system from e.g. suspend
+to RAM or power off. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the wakeup protocol is altered.
+
+
+.. _sys_class_rc_rcN_wakeup_filter_mask:
+
+/sys/class/rc/rcN/wakeup_filter_mask
+====================================
+
+Sets the scancode wakeup filter mask of bits to compare. Use in
+combination with ``/sys/class/rc/rcN/wakeup_filter`` to set the bits of
+the scancode which should be compared against the expected value to
+trigger a system wake event.

+************************
+Remote controller tables
+************************
+
+Unfortunately, for several years, there was no effort to create uniform
+IR keycodes for different devices. This caused the same IR keyname to be
+mapped completely differently on different IR devices. This resulted
+that the same IR keyname to be mapped completely different on different
+IR's. Due to that, V4L2 API now specifies a standard for mapping Media
+keys on IR.
+
+This standard should be used by both V4L/DVB drivers and userspace
+applications
+
+The modules register the remote as keyboard within the linux input
+layer. This means that the IR key strokes will look like normal keyboard
+key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event
+devices (CONFIG_INPUT_EVDEV) it is possible for applications to access
+the remote via /dev/input/event devices.

+Application Priority
+********************
+
+When multiple applications share a device it may be desirable to assign
+them different priorities. Contrary to the traditional "rm -rf /" school
+of thought, a video recording application could for example block other
+applications from changing video controls or switching the current TV
+channel. Another objective is to permit low priority applications
+working in background, which can be preempted by user controlled
+applications and automatically regain control of the device at a later
+time.
+
+Since these features cannot be implemented entirely in user space V4L2
+defines the :ref:`VIDIOC_G_PRIORITY <VIDIOC_G_PRIORITY>` and
+:ref:`VIDIOC_S_PRIORITY <VIDIOC_G_PRIORITY>` ioctls to request and
+query the access priority associate with a file descriptor. Opening a
+device assigns a medium priority, compatible with earlier versions of
+V4L2 and drivers not supporting these ioctls. Applications requiring a
+different priority will usually call :ref:`VIDIOC_S_PRIORITY
+<VIDIOC_G_PRIORITY>` after verifying the device with the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+Ioctls changing driver properties, such as
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>`, return an ``EBUSY`` error code
+after another application obtained higher priority.

+Audio Inputs and Outputs
+************************
+
+Audio inputs and outputs are physical connectors of a device. Video
+capture devices have inputs, output devices have outputs, zero or more
+each. Radio devices have no audio inputs or outputs. They have exactly
+one tuner which in fact *is* an audio source, but this API associates
+tuners with video inputs or outputs only, and radio devices have none of
+these. [#f1]_ A connector on a TV card to loop back the received audio
+signal to a sound card is not considered an audio output.
+
+Audio and video inputs and outputs are associated. Selecting a video
+source also selects an audio source. This is most evident when the video
+and audio source is a tuner. Further audio connectors can combine with
+more than one video input or output. Assumed two composite video inputs
+and two audio inputs exist, there may be up to four valid combinations.
+The relation of video and audio connectors is defined in the
+``audioset`` field of the respective struct
+:c:type:`v4l2_input` or struct
+:c:type:`v4l2_output`, where each bit represents the index
+number, starting at zero, of one audio input or output.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMAUDIO` and
+:ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` ioctl, respectively.
+The struct :c:type:`v4l2_audio` returned by the
+:ref:`VIDIOC_ENUMAUDIO` ioctl also contains signal
+status information applicable when the current audio input is queried.
+
+The :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` ioctls report the current
+audio input and output, respectively.
+
+.. note::
+
+   Note that, unlike :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+   :ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` these ioctls return a
+   structure as :ref:`VIDIOC_ENUMAUDIO` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` do, not just an index.
+
+To select an audio input and change its properties applications call the
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` ioctl. To select an audio
+output (which presently has no changeable properties) applications call
+the :ref:`VIDIOC_S_AUDOUT <VIDIOC_G_AUDOUT>` ioctl.
+
+Drivers must implement all audio input ioctls when the device has
+multiple selectable audio inputs, all audio output ioctls when the
+device has multiple selectable audio outputs. When the device has any
+audio inputs or outputs the driver must set the ``V4L2_CAP_AUDIO`` flag
+in the struct :c:type:`v4l2_capability` returned by
+the :ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Example: Information about the current audio input
+==================================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio));
+
+    if (-1 == ioctl(fd, VIDIOC_G_AUDIO, &audio)) {
+	perror("VIDIOC_G_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+    printf("Current input: %s\\n", audio.name);
+
+
+Example: Switching to the first audio input
+===========================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio)); /* clear audio.mode, audio.reserved */
+
+    audio.index = 0;
+
+    if (-1 == ioctl(fd, VIDIOC_S_AUDIO, &audio)) {
+	perror("VIDIOC_S_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+.. [#f1]
+   Actually struct :c:type:`v4l2_audio` ought to have a
+   ``tuner`` field like struct :c:type:`v4l2_input`, not
+   only making the API more consistent but also permitting radio devices
+   with multiple tuners.

+Buffers
+*******
+
+A buffer contains data exchanged by application and driver using one of
+the Streaming I/O methods. In the multi-planar API, the data is held in
+planes, while the buffer structure acts as a container for the planes.
+Only pointers to buffers (planes) are exchanged, the data itself is not
+copied. These pointers, together with meta-information like timestamps
+or field parity, are stored in a struct :c:type:`v4l2_buffer`,
+argument to the :ref:`VIDIOC_QUERYBUF`,
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` and
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. In the multi-planar API,
+some plane-specific members of struct :c:type:`v4l2_buffer`,
+such as pointers and sizes for each plane, are stored in struct
+struct :c:type:`v4l2_plane` instead. In that case, struct
+struct :c:type:`v4l2_buffer` contains an array of plane structures.
+
+Dequeued video buffers come with timestamps. The driver decides at which
+part of the frame and with which clock the timestamp is taken. Please
+see flags in the masks ``V4L2_BUF_FLAG_TIMESTAMP_MASK`` and
+``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` in :ref:`buffer-flags`. These flags
+are always valid and constant across all buffers during the whole video
+stream. Changes in these flags may take place as a side effect of
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` or
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` however. The
+``V4L2_BUF_FLAG_TIMESTAMP_COPY`` timestamp type which is used by e.g. on
+mem-to-mem devices is an exception to the rule: the timestamp source
+flags are copied from the OUTPUT video buffer to the CAPTURE video
+buffer.
+
+
+Interactions between formats, controls and buffers
+==================================================
+
+V4L2 exposes parameters that influence the buffer size, or the way data is
+laid out in the buffer. Those parameters are exposed through both formats and
+controls. One example of such a control is the ``V4L2_CID_ROTATE`` control
+that modifies the direction in which pixels are stored in the buffer, as well
+as the buffer size when the selected format includes padding at the end of
+lines.
+
+The set of information needed to interpret the content of a buffer (e.g. the
+pixel format, the line stride, the tiling orientation or the rotation) is
+collectively referred to in the rest of this section as the buffer layout.
+
+Controls that can modify the buffer layout shall set the
+``V4L2_CTRL_FLAG_MODIFY_LAYOUT`` flag.
+
+Modifying formats or controls that influence the buffer size or layout require
+the stream to be stopped. Any attempt at such a modification while the stream
+is active shall cause the ioctl setting the format or the control to return
+the ``EBUSY`` error code. In that case drivers shall also set the
+``V4L2_CTRL_FLAG_GRABBED`` flag when calling
+:c:func:`VIDIOC_QUERYCTRL` or :c:func:`VIDIOC_QUERY_EXT_CTRL` for such a
+control while the stream is active.
+
+.. note::
+
+   The :c:func:`VIDIOC_S_SELECTION` ioctl can, depending on the hardware (for
+   instance if the device doesn't include a scaler), modify the format in
+   addition to the selection rectangle. Similarly, the
+   :c:func:`VIDIOC_S_INPUT`, :c:func:`VIDIOC_S_OUTPUT`, :c:func:`VIDIOC_S_STD`
+   and :c:func:`VIDIOC_S_DV_TIMINGS` ioctls can also modify the format and
+   selection rectangles. When those ioctls result in a buffer size or layout
+   change, drivers shall handle that condition as they would handle it in the
+   :c:func:`VIDIOC_S_FMT` ioctl in all cases described in this section.
+
+Controls that only influence the buffer layout can be modified at any time
+when the stream is stopped. As they don't influence the buffer size, no
+special handling is needed to synchronize those controls with buffer
+allocation and the ``V4L2_CTRL_FLAG_GRABBED`` flag is cleared once the
+stream is stopped.
+
+Formats and controls that influence the buffer size interact with buffer
+allocation. The simplest way to handle this is for drivers to always require
+buffers to be reallocated in order to change those formats or controls. In
+that case, to perform such changes, userspace applications shall first stop
+the video stream with the :c:func:`VIDIOC_STREAMOFF` ioctl if it is running
+and free all buffers with the :c:func:`VIDIOC_REQBUFS` ioctl if they are
+allocated. After freeing all buffers the ``V4L2_CTRL_FLAG_GRABBED`` flag
+for controls is cleared. The format or controls can then be modified, and
+buffers shall then be reallocated and the stream restarted. A typical ioctl
+sequence is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_REQBUFS(0)
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_REQBUFS(n)
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+The second :c:func:`VIDIOC_REQBUFS` call will take the new format and control
+value into account to compute the buffer size to allocate. Applications can
+also retrieve the size by calling the :c:func:`VIDIOC_G_FMT` ioctl if needed.
+
+.. note::
+
+   The API doesn't mandate the above order for control (3.) and format (4.)
+   changes. Format and controls can be set in a different order, or even
+   interleaved, depending on the device and use case. For instance some
+   controls might behave differently for different pixel formats, in which
+   case the format might need to be set first.
+
+When reallocation is required, any attempt to modify format or controls that
+influences the buffer size while buffers are allocated shall cause the format
+or control set ioctl to return the ``EBUSY`` error. Any attempt to queue a
+buffer too small for the current format or controls shall cause the
+:c:func:`VIDIOC_QBUF` ioctl to return a ``EINVAL`` error.
+
+Buffer reallocation is an expensive operation. To avoid that cost, drivers can
+(and are encouraged to) allow format or controls that influence the buffer
+size to be changed with buffers allocated. In that case, a typical ioctl
+sequence to modify format and controls is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+For this sequence to operate correctly, queued buffers need to be large enough
+for the new format or controls. Drivers shall return a ``ENOSPC`` error in
+response to format change (:c:func:`VIDIOC_S_FMT`) or control changes
+(:c:func:`VIDIOC_S_CTRL` or :c:func:`VIDIOC_S_EXT_CTRLS`) if buffers too small
+for the new format are currently queued. As a simplification, drivers are
+allowed to return a ``EBUSY`` error from these ioctls if any buffer is
+currently queued, without checking the queued buffers sizes.
+
+Additionally, drivers shall return a ``EINVAL`` error from the
+:c:func:`VIDIOC_QBUF` ioctl if the buffer being queued is too small for the
+current format or controls. Together, these requirements ensure that queued
+buffers will always be large enough for the configured format and controls.
+
+Userspace applications can query the buffer size required for a given format
+and controls by first setting the desired control values and then trying the
+desired format. The :c:func:`VIDIOC_TRY_FMT` ioctl will return the required
+buffer size.
+
+ #. VIDIOC_S_EXT_CTRLS(x)
+ #. VIDIOC_TRY_FMT()
+ #. VIDIOC_S_EXT_CTRLS(y)
+ #. VIDIOC_TRY_FMT()
+
+The :c:func:`VIDIOC_CREATE_BUFS` ioctl can then be used to allocate buffers
+based on the queried sizes (for instance by allocating a set of buffers large
+enough for all the desired formats and controls, or by allocating separate set
+of appropriately sized buffers for each use case).

+	allocated with the :ref:`VIDIOC_REQBUFS` ioctl
+	(struct :c:type:`v4l2_requestbuffers`
+	``count``), plus any buffers allocated with
+	:ref:`VIDIOC_CREATE_BUFS` minus one.
+    * - __u32
+      - ``type``
+      - Type of the buffer, same as struct
+	:c:type:`v4l2_format` ``type`` or struct
+	:c:type:`v4l2_requestbuffers` ``type``, set
+	by the application. See :c:type:`v4l2_buf_type`
+    * - __u32
+      - ``bytesused``
+      - The number of bytes occupied by the data in the buffer. It depends
+	on the negotiated data format and may change with each buffer for
+	compressed variable size data like JPEG images. Drivers must set
+	this field when ``type`` refers to a capture stream, applications
+	when it refers to an output stream. If the application sets this
+	to 0 for an output stream, then ``bytesused`` will be set to the
+	size of the buffer (see the ``length`` field of this struct) by
+	the driver. For multiplanar formats this field is ignored and the
+	``planes`` pointer is used instead.
+    * - __u32
+      - ``flags``
+      - Flags set by the application or driver, see :ref:`buffer-flags`.
+    * - __u32
+      - ``field``
+      - Indicates the field order of the image in the buffer, see
+	:c:type:`v4l2_field`. This field is not used when the buffer
+	contains VBI data. Drivers must set it when ``type`` refers to a
+	capture stream, applications when it refers to an output stream.
+    * - struct timeval
+      - ``timestamp``
+      - For capture streams this is time when the first data byte was
+	captured, as returned by the :c:func:`clock_gettime()` function
+	for the relevant clock id; see ``V4L2_BUF_FLAG_TIMESTAMP_*`` in
+	:ref:`buffer-flags`. For output streams the driver stores the
+	time at which the last data byte was actually sent out in the
+	``timestamp`` field. This permits applications to monitor the
+	drift between the video and system clock. For output streams that
+	use ``V4L2_BUF_FLAG_TIMESTAMP_COPY`` the application has to fill
+	in the timestamp which will be copied by the driver to the capture
+	stream.
+    * - struct :c:type:`v4l2_timecode`
+      - ``timecode``
+      - When the ``V4L2_BUF_FLAG_TIMECODE`` flag is set in ``flags``, this
+	structure contains a frame timecode. In
+	:c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
+	bottom field contain the same timecode. Timecodes are intended to
+	help video editing and are typically recorded on video tapes, but
+	also embedded in compressed formats like MPEG. This field is
+	independent of the ``timestamp`` and ``sequence`` fields.
+    * - __u32
+      - ``sequence``
+      - Set by the driver, counting the frames (not fields!) in sequence.
+	This field is set for both input and output devices.
+    * - :cspan:`2`
+
+	In :c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
+	bottom field have the same sequence number. The count starts at
+	zero and includes dropped or repeated frames. A dropped frame was
+	received by an input device but could not be stored due to lack of
+	free buffer space. A repeated frame was displayed again by an
+	output device because the application did not pass new data in
+	time.
+
+	.. note::
+
+	   This may count the frames received e.g. over USB, without
+	   taking into account the frames dropped by the remote hardware due
+	   to limited compression throughput or bus bandwidth. These devices
+	   identify by not enumerating any video standards, see
+	   :ref:`standard`.
+
+    * - __u32

+	See :ref:`mmap` for details
+    * - unsigned long
+      - ``userptr``
+      - For the single-planar API and when ``memory`` is

+	:ref:`userp` for details.
+    * - struct v4l2_plane
+      - ``*planes``
+      - When using the multi-planar API, contains a userspace pointer to

+	the array should be put in the ``length`` field of this
+	struct :c:type:`v4l2_buffer` structure.
+    * - int
+      - ``fd``
+      - For the single-plane API and when ``memory`` is
+	``V4L2_MEMORY_DMABUF`` this is the file descriptor associated with
+	a DMABUF buffer.
+    * - }
+      -
+    * - __u32
+      - ``length``
+      - Size of the buffer (not the payload) in bytes for the
+	single-planar API. This is set by the driver based on the calls to
+	:ref:`VIDIOC_REQBUFS` and/or
+	:ref:`VIDIOC_CREATE_BUFS`. For the
+	multi-planar API the application sets this to the number of
+	elements in the ``planes`` array. The driver will fill in the
+	actual number of valid elements in that array.
+    * - __u32
+      - ``reserved2``
+      - A place holder for future extensions. Drivers and applications
+	must set this to 0.
+    * - __u32
+      - ``request_fd``
+      - The file descriptor of the request to queue the buffer to. If the flag
+        ``V4L2_BUF_FLAG_REQUEST_FD`` is set, then the buffer will be
+	queued to this request. If the flag is not set, then this field will
+	be ignored.
+
+	The ``V4L2_BUF_FLAG_REQUEST_FD`` flag and this field are only used by
+	:ref:`ioctl VIDIOC_QBUF <VIDIOC_QBUF>` and ignored by other ioctls that
+	take a :c:type:`v4l2_buffer` as argument.
+
+	Applications should not set ``V4L2_BUF_FLAG_REQUEST_FD`` for any ioctls
+	other than :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`.
+
+	If the device does not support requests, then ``EBADR`` will be returned.
+	If requests are supported but an invalid request file descriptor is
+	given, then ``EINVAL`` will be returned.

+	the incoming queue. It automatically moves to the outgoing queue
+	after the buffer has been filled (capture devices) or displayed
+	(output devices). Drivers set or clear this flag when the

+
+      - ``V4L2_BUF_FLAG_BFRAME``
+      - 0x00000020
+      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional

+      - 0x00000400
+      - The buffer has been prepared for I/O and can be queued by the
+	application. Drivers set or clear this flag when the
+	:ref:`VIDIOC_QUERYBUF`,
+	:ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
+	:ref:`VIDIOC_QBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
+      - 0x00000800
+      - Caches do not have to be invalidated for this buffer. Typically
+	applications shall use this flag if the data captured in the
+	buffer is not going to be touched by the CPU, instead the buffer
+	will, probably, be passed on to a DMA-capable hardware unit for
+	further processing or output.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
+      - 0x00001000
+      - Caches do not have to be cleaned for this buffer. Typically
+	applications shall use this flag for output buffers if the data in
+	this buffer has not been created by the CPU but by some
+	DMA-capable unit, in which case caches have not been used.
+    * .. _`V4L2-BUF-FLAG-M2M-HOLD-CAPTURE-BUF`:
+
+      - ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF``
+      - 0x00000200
+      - Only valid if ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` is
+	set. It is typically used with stateless decoders where multiple
+	output buffers each decode to a slice of the decoded frame.
+	Applications can set this flag when queueing the output buffer
+	to prevent the driver from dequeueing the capture buffer after
+	the output buffer has been decoded (i.e. the capture buffer is
+	'held'). If the timestamp of this output buffer differs from that
+	of the previous output buffer, then that indicates the start of a
+	new frame and the previously held capture buffer is dequeued.
+    * .. _`V4L2-BUF-FLAG-LAST`:
+
+      - ``V4L2_BUF_FLAG_LAST``
+      - 0x00100000
+      - Last buffer produced by the hardware. mem2mem codec drivers set
+	this flag on the capture queue for the last buffer when the
+	:ref:`VIDIOC_QUERYBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
+	hardware limitations, the last buffer may be empty. In this case
+	the driver will set the ``bytesused`` field to 0, regardless of
+	the format. Any Any subsequent call to the
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
+	but return an ``EPIPE`` error code.
+    * .. _`V4L2-BUF-FLAG-REQUEST-FD`:
+
+      - ``V4L2_BUF_FLAG_REQUEST_FD``
+      - 0x00800000
+      - The ``request_fd`` field contains a valid file descriptor.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
+      - 0x0000e000
+      - Mask for timestamp types below. To test the timestamp type, mask
+	out bits not belonging to timestamp type by performing a logical
+	and operation with buffer flags and timestamp mask.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
+      - 0x00000000
+      - Unknown timestamp type. This type is used by drivers before Linux
+	3.9 and may be either monotonic (see below) or realtime (wall
+	clock). Monotonic clock has been favoured in embedded systems
+	whereas most of the drivers use the realtime clock. Either kinds
+	of timestamps are available in user space via
+	:c:func:`clock_gettime` using clock IDs ``CLOCK_MONOTONIC``
+	and ``CLOCK_REALTIME``, respectively.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
+      - 0x00002000
+      - The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
+	clock. To access the same clock outside V4L2, use
+	:c:func:`clock_gettime`.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
+      - 0x00004000
+      - The CAPTURE buffer timestamp has been taken from the corresponding
+	OUTPUT buffer. This flag applies only to mem2mem devices.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
+      - 0x00070000
+      - Mask for timestamp sources below. The timestamp source defines the
+	point of time the timestamp is taken in relation to the frame.
+	Logical 'and' operation between the ``flags`` field and
+	``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` produces the value of the
+	timestamp source. Applications must set the timestamp source when
+	``type`` refers to an output stream and
+	``V4L2_BUF_FLAG_TIMESTAMP_COPY`` is set.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-EOF`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
+      - 0x00000000
+      - End Of Frame. The buffer timestamp has been taken when the last
+	pixel of the frame has been received or the last pixel of the
+	frame has been transmitted. In practice, software generated
+	timestamps will typically be read from the clock a small amount of
+	time after the last pixel has been received or transmitten,
+	depending on the system and other activity in it.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-SOE`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_SOE``
+      - 0x00010000
+      - Start Of Exposure. The buffer timestamp has been taken when the
+	exposure of the frame has begun. This is only valid for the
+	``V4L2_BUF_TYPE_VIDEO_CAPTURE`` buffer type.

+****************************
+Defining Colorspaces in V4L2
+****************************
+
+In V4L2 colorspaces are defined by four values. The first is the
+colorspace identifier (enum :c:type:`v4l2_colorspace`)
+which defines the chromaticities, the default transfer function, the
+default Y'CbCr encoding and the default quantization method. The second
+is the transfer function identifier (enum
+:c:type:`v4l2_xfer_func`) to specify non-standard
+transfer functions. The third is the Y'CbCr encoding identifier (enum
+:c:type:`v4l2_ycbcr_encoding`) to specify
+non-standard Y'CbCr encodings and the fourth is the quantization
+identifier (enum :c:type:`v4l2_quantization`) to
+specify non-standard quantization methods. Most of the time only the
+colorspace field of struct :c:type:`v4l2_pix_format`
+or struct :c:type:`v4l2_pix_format_mplane`
+needs to be filled in.
+
+.. _hsv-colorspace:
+
+On :ref:`HSV formats <hsv-formats>` the *Hue* is defined as the angle on
+the cylindrical color representation. Usually this angle is measured in
+degrees, i.e. 0-360. When we map this angle value into 8 bits, there are
+two basic ways to do it: Divide the angular value by 2 (0-179), or use the
+whole range, 0-255, dividing the angular value by 1.41. The enum
+:c:type:`v4l2_hsv_encoding` specifies which encoding is used.
+
+.. note:: The default R'G'B' quantization is full range for all
+   colorspaces except for BT.2020 which uses limited range R'G'B'
+   quantization.

+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range

+
+The default quantization is limited range, but full range is possible

+
+The ``V4L2_YCBCR_ENC_709`` encoding described above is the default for
+this colorspace, but it can be overridden with ``V4L2_YCBCR_ENC_601``,
+in which case the BT.601 Y'CbCr encoding is used.
+
+Two additional extended gamut Y'CbCr encodings are also possible with
+this colorspace:
+
+The xvYCC 709 encoding (``V4L2_YCBCR_ENC_XV709``, :ref:`xvycc`) is
+similar to the Rec. 709 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset according to the limited range formula:
+
+.. math::
+
+    Y' = \frac{219}{256} * (0.2126R' + 0.7152G' + 0.0722B') + \frac{16}{256}

+    Cb = \frac{224}{256} * (-0.1146R' - 0.3854G' + 0.5B')
+
+    Cr = \frac{224}{256} * (0.5R' - 0.4542G' - 0.0458B')
+
+The xvYCC 601 encoding (``V4L2_YCBCR_ENC_XV601``, :ref:`xvycc`) is
+similar to the BT.601 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset according to the limited range formula:
+
+.. math::
+
+    Y' = \frac{219}{256} * (0.2990R' + 0.5870G' + 0.1140B') + \frac{16}{256}
+
+    Cb = \frac{224}{256} * (-0.1687R' - 0.3313G' + 0.5B')
+
+    Cr = \frac{224}{256} * (0.5R' - 0.4187G' - 0.0813B')
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5] and quantized without further scaling or offsets.
+The non-standard xvYCC 709 or xvYCC 601 encodings can be
+used by selecting ``V4L2_YCBCR_ENC_XV709`` or ``V4L2_YCBCR_ENC_XV601``.
+As seen by the xvYCC formulas these encodings always use limited range quantization,
+there is no full range variant. The whole point of these extended gamut encodings
+is that values outside the limited range are still valid, although they
+map to R', G' and B' values outside the [0…1] range and are therefore outside
+the Rec. 709 colorspace gamut.

+``V4L2_XFER_FUNC_SRGB``. The default Y'CbCr encoding is
+``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited range.
+
+Note that the :ref:`sycc` standard specifies full range quantization,
+however all current capture hardware supported by the kernel convert
+R'G'B' to limited range Y'CbCr. So choosing full range as the default
+would break how applications interpret the quantization range.

+Transfer Function SMPTE 2084 (V4L2_XFER_FUNC_SMPTE2084)
+=======================================================
+
+The :ref:`smpte2084` standard defines the transfer function used by
+High Dynamic Range content.
+
+Constants:
+    m1 = (2610 / 4096) / 4
+
+    m2 = (2523 / 4096) * 128
+
+    c1 = 3424 / 4096
+
+    c2 = (2413 / 4096) * 32
+
+    c3 = (2392 / 4096) * 32
+
+Transfer function:
+    L' = ((c1 + c2 * L\ :sup:`m1`) / (1 + c3 * L\ :sup:`m1`))\ :sup:`m2`
+
+Inverse Transfer function:
+    L = (max(L':sup:`1/m2` - c1, 0) / (c2 - c3 *
+    L'\ :sup:`1/m2`))\ :sup:`1/m1`
+
+Take care when converting between this transfer function and non-HDR transfer
+functions: the linear RGB values [0…1] of HDR content map to a luminance range
+of 0 to 10000 cd/m\ :sup:`2` whereas the linear RGB values of non-HDR (aka
+Standard Dynamic Range or SDR) map to a luminance range of 0 to 100 cd/m\ :sup:`2`.
+
+To go from SDR to HDR you will have to divide L by 100 first. To go in the other
+direction you will have to multiply L by 100. Of course, this clamps all
+luminance values over 100 cd/m\ :sup:`2` to 100 cd/m\ :sup:`2`.
+
+There are better methods, see e.g. :ref:`colimg` for more in-depth information
+about this.

+
+***********
+Colorspaces
+***********
+
+'Color' is a very complex concept and depends on physics, chemistry and
+biology. Just because you have three numbers that describe the 'red',
+'green' and 'blue' components of the color of a pixel does not mean that
+you can accurately display that color. A colorspace defines what it
+actually *means* to have an RGB value of e.g. (255, 0, 0). That is,
+which color should be reproduced on the screen in a perfectly calibrated
+environment.
+
+In order to do that we first need to have a good definition of color,
+i.e. some way to uniquely and unambiguously define a color so that
+someone else can reproduce it. Human color vision is trichromatic since
+the human eye has color receptors that are sensitive to three different
+wavelengths of light. Hence the need to use three numbers to describe
+color. Be glad you are not a mantis shrimp as those are sensitive to 12
+different wavelengths, so instead of RGB we would be using the
+ABCDEFGHIJKL colorspace...
+
+Color exists only in the eye and brain and is the result of how strongly
+color receptors are stimulated. This is based on the Spectral Power
+Distribution (SPD) which is a graph showing the intensity (radiant
+power) of the light at wavelengths covering the visible spectrum as it
+enters the eye. The science of colorimetry is about the relationship
+between the SPD and color as perceived by the human brain.
+
+Since the human eye has only three color receptors it is perfectly
+possible that different SPDs will result in the same stimulation of
+those receptors and are perceived as the same color, even though the SPD
+of the light is different.
+
+In the 1920s experiments were devised to determine the relationship
+between SPDs and the perceived color and that resulted in the CIE 1931
+standard that defines spectral weighting functions that model the
+perception of color. Specifically that standard defines functions that
+can take an SPD and calculate the stimulus for each color receptor.
+After some further mathematical transforms these stimuli are known as
+the *CIE XYZ tristimulus* values and these X, Y and Z values describe a
+color as perceived by a human unambiguously. These X, Y and Z values are
+all in the range [0…1].
+
+The Y value in the CIE XYZ colorspace corresponds to luminance. Often
+the CIE XYZ colorspace is transformed to the normalized CIE xyY
+colorspace:
+
+	x = X / (X + Y + Z)
+
+	y = Y / (X + Y + Z)
+
+The x and y values are the chromaticity coordinates and can be used to
+define a color without the luminance component Y. It is very confusing
+to have such similar names for these colorspaces. Just be aware that if
+colors are specified with lower case 'x' and 'y', then the CIE xyY
+colorspace is used. Upper case 'X' and 'Y' refer to the CIE XYZ
+colorspace. Also, y has nothing to do with luminance. Together x and y
+specify a color, and Y the luminance. That is really all you need to
+remember from a practical point of view. At the end of this section you
+will find reading resources that go into much more detail if you are
+interested.
+
+A monitor or TV will reproduce colors by emitting light at three
+different wavelengths, the combination of which will stimulate the color
+receptors in the eye and thus cause the perception of color.
+Historically these wavelengths were defined by the red, green and blue
+phosphors used in the displays. These *color primaries* are part of what
+defines a colorspace.
+
+Different display devices will have different primaries and some
+primaries are more suitable for some display technologies than others.
+This has resulted in a variety of colorspaces that are used for
+different display technologies or uses. To define a colorspace you need
+to define the three color primaries (these are typically defined as x, y
+chromaticity coordinates from the CIE xyY colorspace) but also the white
+reference: that is the color obtained when all three primaries are at
+maximum power. This determines the relative power or energy of the
+primaries. This is usually chosen to be close to daylight which has been
+defined as the CIE D65 Illuminant.
+
+To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
+Other colorspaces are defined by three chromaticity coordinates defined
+in the CIE xyY colorspace. Based on those a 3x3 matrix can be
+constructed that transforms CIE XYZ colors to colors in the new
+colorspace.
+
+Both the CIE XYZ and the RGB colorspace that are derived from the
+specific chromaticity primaries are linear colorspaces. But neither the
+eye, nor display technology is linear. Doubling the values of all
+components in the linear colorspace will not be perceived as twice the
+intensity of the color. So each colorspace also defines a transfer
+function that takes a linear color component value and transforms it to
+the non-linear component value, which is a closer match to the
+non-linear performance of both the eye and displays. Linear component
+values are denoted RGB, non-linear are denoted as R'G'B'. In general
+colors used in graphics are all R'G'B', except in openGL which uses
+linear RGB. Special care should be taken when dealing with openGL to
+provide linear RGB colors or to use the built-in openGL support to apply
+the inverse transfer function.
+
+The final piece that defines a colorspace is a function that transforms
+non-linear R'G'B' to non-linear Y'CbCr. This function is determined by
+the so-called luma coefficients. There may be multiple possible Y'CbCr
+encodings allowed for the same colorspace. Many encodings of color
+prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the
+human eye is more sensitive to differences in luminance than in color
+this encoding allows one to reduce the amount of color information
+compared to the luma data. Note that the luma (Y') is unrelated to the Y
+in the CIE XYZ colorspace. Also note that Y'CbCr is often called YCbCr
+or YUV even though these are strictly speaking wrong.
+
+Sometimes people confuse Y'CbCr as being a colorspace. This is not
+correct, it is just an encoding of an R'G'B' color into luma and chroma
+values. The underlying colorspace that is associated with the R'G'B'
+color is also associated with the Y'CbCr color.
+
+The final step is how the RGB, R'G'B' or Y'CbCr values are quantized.
+The CIE XYZ colorspace where X, Y and Z are in the range [0…1] describes
+all colors that humans can perceive, but the transform to another
+colorspace will produce colors that are outside the [0…1] range. Once
+clamped to the [0…1] range those colors can no longer be reproduced in
+that colorspace. This clamping is what reduces the extent or gamut of
+the colorspace. How the range of [0…1] is translated to integer values
+in the range of [0…255] (or higher, depending on the color depth) is
+called the quantization. This is *not* part of the colorspace
+definition. In practice RGB or R'G'B' values are full range, i.e. they
+use the full [0…255] range. Y'CbCr values on the other hand are limited
+range with Y' using [16…235] and Cb and Cr using [16…240].
+
+Unfortunately, in some cases limited range RGB is also used where the
+components use the range [16…235]. And full range Y'CbCr also exists
+using the [0…255] range.
+
+In order to correctly interpret a color you need to know the
+quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr
+encoding and the colorspace. From that information you can calculate the
+corresponding CIE XYZ color and map that again to whatever colorspace
+your display device uses.
+
+The colorspace definition itself consists of the three chromaticity
+primaries, the white reference chromaticity, a transfer function and the
+luma coefficients needed to transform R'G'B' to Y'CbCr. While some
+colorspace standards correctly define all four, quite often the
+colorspace standard only defines some, and you have to rely on other
+standards for the missing pieces. The fact that colorspaces are often a
+mix of different standards also led to very confusing naming conventions
+where the name of a standard was used to name a colorspace when in fact
+that standard was part of various other colorspaces as well.
+
+If you want to read more about colors and colorspaces, then the
+following resources are useful: :ref:`poynton` is a good practical
+book for video engineers, :ref:`colimg` has a much broader scope and
+describes many more aspects of color (physics, chemistry, biology,
+etc.). The
+`http://www.brucelindbloom.com <http://www.brucelindbloom.com>`__
+website is an excellent resource, especially with respect to the
+mathematics behind colorspace conversions. The wikipedia
+`CIE 1931 colorspace <http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space>`__
+article is also very useful.

+*************
+User Controls
+*************
+
+Devices typically have a number of user-settable controls such as
+brightness, saturation and so on, which would be presented to the user
+on a graphical user interface. But, different devices will have
+different controls available, and furthermore, the range of possible
+values, and the default value will vary from device to device. The
+control ioctls provide the information and a mechanism to create a nice
+user interface for these controls that will work correctly with any
+device.
+
+All controls are accessed using an ID value. V4L2 defines several IDs
+for specific purposes. Drivers can also implement their own custom
+controls using ``V4L2_CID_PRIVATE_BASE``  [#f1]_ and higher values. The
+pre-defined control IDs have the prefix ``V4L2_CID_``, and are listed in
+:ref:`control-id`. The ID is used when querying the attributes of a
+control, and when getting or setting the current value.
+
+Generally applications should present controls to the user without
+assumptions about their purpose. Each control comes with a name string
+the user is supposed to understand. When the purpose is non-intuitive
+the driver writer should provide a user manual, a user interface plug-in
+or a driver specific panel application. Predefined IDs were introduced
+to change a few controls programmatically, for example to mute a device
+during a channel switch.
+
+Drivers may enumerate different controls after switching the current
+video input or output, tuner or modulator, or audio input or output.
+Different in the sense of other bounds, another default and current
+value, step size or other menu items. A control with a certain *custom*
+ID can also change name and type.
+
+If a control is not applicable to the current configuration of the
+device (for example, it doesn't apply to the current video input)
+drivers set the ``V4L2_CTRL_FLAG_INACTIVE`` flag.
+
+Control values are stored globally, they do not change when switching
+except to stay within the reported bounds. They also do not change e. g.
+when the device is opened or closed, when the tuner radio frequency is
+changed or generally never without application request.
+
+V4L2 specifies an event mechanism to notify applications when controls
+change value (see
+:ref:`VIDIOC_SUBSCRIBE_EVENT`, event
+``V4L2_EVENT_CTRL``), panel applications might want to make use of that
+in order to always reflect the correct control value.
+
+All controls use machine endianness.
+
+
+.. _control-id:
+
+Control IDs
+===========
+
+``V4L2_CID_BASE``
+    First predefined ID, equal to ``V4L2_CID_BRIGHTNESS``.
+
+``V4L2_CID_USER_BASE``
+    Synonym of ``V4L2_CID_BASE``.
+
+``V4L2_CID_BRIGHTNESS`` ``(integer)``
+    Picture brightness, or more precisely, the black level.
+
+``V4L2_CID_CONTRAST`` ``(integer)``
+    Picture contrast or luma gain.
+
+``V4L2_CID_SATURATION`` ``(integer)``
+    Picture color saturation or chroma gain.
+
+``V4L2_CID_HUE`` ``(integer)``
+    Hue or color balance.
+
+``V4L2_CID_AUDIO_VOLUME`` ``(integer)``
+    Overall audio volume. Note some drivers also provide an OSS or ALSA
+    mixer interface.
+
+``V4L2_CID_AUDIO_BALANCE`` ``(integer)``
+    Audio stereo balance. Minimum corresponds to all the way left,
+    maximum to right.
+
+``V4L2_CID_AUDIO_BASS`` ``(integer)``
+    Audio bass adjustment.
+
+``V4L2_CID_AUDIO_TREBLE`` ``(integer)``
+    Audio treble adjustment.
+
+``V4L2_CID_AUDIO_MUTE`` ``(boolean)``
+    Mute audio, i. e. set the volume to zero, however without affecting
+    ``V4L2_CID_AUDIO_VOLUME``. Like ALSA drivers, V4L2 drivers must mute
+    at load time to avoid excessive noise. Actually the entire device
+    should be reset to a low power consumption state.
+
+``V4L2_CID_AUDIO_LOUDNESS`` ``(boolean)``
+    Loudness mode (bass boost).
+
+``V4L2_CID_BLACK_LEVEL`` ``(integer)``
+    Another name for brightness (not a synonym of
+    ``V4L2_CID_BRIGHTNESS``). This control is deprecated and should not
+    be used in new drivers and applications.
+
+``V4L2_CID_AUTO_WHITE_BALANCE`` ``(boolean)``
+    Automatic white balance (cameras).
+
+``V4L2_CID_DO_WHITE_BALANCE`` ``(button)``
+    This is an action control. When set (the value is ignored), the
+    device will do a white balance and then hold the current setting.
+    Contrast this with the boolean ``V4L2_CID_AUTO_WHITE_BALANCE``,
+    which, when activated, keeps adjusting the white balance.
+
+``V4L2_CID_RED_BALANCE`` ``(integer)``
+    Red chroma balance.
+
+``V4L2_CID_BLUE_BALANCE`` ``(integer)``
+    Blue chroma balance.
+
+``V4L2_CID_GAMMA`` ``(integer)``
+    Gamma adjust.
+
+``V4L2_CID_WHITENESS`` ``(integer)``
+    Whiteness for grey-scale devices. This is a synonym for
+    ``V4L2_CID_GAMMA``. This control is deprecated and should not be
+    used in new drivers and applications.
+
+``V4L2_CID_EXPOSURE`` ``(integer)``
+    Exposure (cameras). [Unit?]
+
+``V4L2_CID_AUTOGAIN`` ``(boolean)``
+    Automatic gain/exposure control.
+
+``V4L2_CID_GAIN`` ``(integer)``
+    Gain control.
+
+    Primarily used to control gain on e.g. TV tuners but also on
+    webcams. Most devices control only digital gain with this control
+    but on some this could include analogue gain as well. Devices that
+    recognise the difference between digital and analogue gain use
+    controls ``V4L2_CID_DIGITAL_GAIN`` and ``V4L2_CID_ANALOGUE_GAIN``.
+
+``V4L2_CID_HFLIP`` ``(boolean)``
+    Mirror the picture horizontally.
+
+``V4L2_CID_VFLIP`` ``(boolean)``
+    Mirror the picture vertically.
+
+.. _v4l2-power-line-frequency:
+
+``V4L2_CID_POWER_LINE_FREQUENCY`` ``(enum)``
+    Enables a power line frequency filter to avoid flicker. Possible
+    values for ``enum v4l2_power_line_frequency`` are:
+    ``V4L2_CID_POWER_LINE_FREQUENCY_DISABLED`` (0),
+    ``V4L2_CID_POWER_LINE_FREQUENCY_50HZ`` (1),
+    ``V4L2_CID_POWER_LINE_FREQUENCY_60HZ`` (2) and
+    ``V4L2_CID_POWER_LINE_FREQUENCY_AUTO`` (3).
+
+``V4L2_CID_HUE_AUTO`` ``(boolean)``
+    Enables automatic hue control by the device. The effect of setting
+    ``V4L2_CID_HUE`` while automatic hue control is enabled is
+    undefined, drivers should ignore such request.
+
+``V4L2_CID_WHITE_BALANCE_TEMPERATURE`` ``(integer)``
+    This control specifies the white balance settings as a color
+    temperature in Kelvin. A driver should have a minimum of 2800
+    (incandescent) to 6500 (daylight). For more information about color
+    temperature see
+    `Wikipedia <http://en.wikipedia.org/wiki/Color_temperature>`__.
+
+``V4L2_CID_SHARPNESS`` ``(integer)``
+    Adjusts the sharpness filters in a camera. The minimum value
+    disables the filters, higher values give a sharper picture.
+
+``V4L2_CID_BACKLIGHT_COMPENSATION`` ``(integer)``
+    Adjusts the backlight compensation in a camera. The minimum value
+    disables backlight compensation.
+
+``V4L2_CID_CHROMA_AGC`` ``(boolean)``
+    Chroma automatic gain control.
+
+``V4L2_CID_CHROMA_GAIN`` ``(integer)``
+    Adjusts the Chroma gain control (for use when chroma AGC is
+    disabled).
+
+``V4L2_CID_COLOR_KILLER`` ``(boolean)``
+    Enable the color killer (i. e. force a black & white image in case
+    of a weak video signal).
+
+.. _v4l2-colorfx:
+
+``V4L2_CID_COLORFX`` ``(enum)``
+    Selects a color effect. The following values are defined:
+
+
+
+.. tabularcolumns:: |p{5.5cm}|p{12cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+    :widths: 11 24
+
+    * - ``V4L2_COLORFX_NONE``
+      - Color effect is disabled.
+    * - ``V4L2_COLORFX_ANTIQUE``
+      - An aging (old photo) effect.
+    * - ``V4L2_COLORFX_ART_FREEZE``
+      - Frost color effect.
+    * - ``V4L2_COLORFX_AQUA``
+      - Water color, cool tone.
+    * - ``V4L2_COLORFX_BW``
+      - Black and white.
+    * - ``V4L2_COLORFX_EMBOSS``
+      - Emboss, the highlights and shadows replace light/dark boundaries
+	and low contrast areas are set to a gray background.
+    * - ``V4L2_COLORFX_GRASS_GREEN``
+      - Grass green.
+    * - ``V4L2_COLORFX_NEGATIVE``

+      - Sketch.
+    * - ``V4L2_COLORFX_SKIN_WHITEN``
+      - Skin whiten.
+    * - ``V4L2_COLORFX_SKY_BLUE``
+      - Sky blue.
+    * - ``V4L2_COLORFX_SOLARIZATION``
+      - Solarization, the image is partially reversed in tone, only color
+	values above or below a certain threshold are inverted.
+    * - ``V4L2_COLORFX_SILHOUETTE``
+      - Silhouette (outline).
+    * - ``V4L2_COLORFX_VIVID``
+      - Vivid colors.
+    * - ``V4L2_COLORFX_SET_CBCR``
+      - The Cb and Cr chroma components are replaced by fixed coefficients
+	determined by ``V4L2_CID_COLORFX_CBCR`` control.
+
+
+
+``V4L2_CID_COLORFX_CBCR`` ``(integer)``
+    Determines the Cb and Cr coefficients for ``V4L2_COLORFX_SET_CBCR``
+    color effect. Bits [7:0] of the supplied 32 bit value are
+    interpreted as Cr component, bits [15:8] as Cb component and bits
+    [31:16] must be zero.
+
+``V4L2_CID_AUTOBRIGHTNESS`` ``(boolean)``
+    Enable Automatic Brightness.
+
+``V4L2_CID_ROTATE`` ``(integer)``
+    Rotates the image by specified angle. Common angles are 90, 270 and
+    180. Rotating the image to 90 and 270 will reverse the height and
+    width of the display window. It is necessary to set the new height
+    and width of the picture using the
+    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl according to the
+    rotation angle selected.
+
+``V4L2_CID_BG_COLOR`` ``(integer)``
+    Sets the background color on the current output device. Background
+    color needs to be specified in the RGB24 format. The supplied 32 bit
+    value is interpreted as bits 0-7 Red color information, bits 8-15
+    Green color information, bits 16-23 Blue color information and bits
+    24-31 must be zero.
+
+``V4L2_CID_ILLUMINATORS_1 V4L2_CID_ILLUMINATORS_2`` ``(boolean)``
+    Switch on or off the illuminator 1 or 2 of the device (usually a
+    microscope).
+
+``V4L2_CID_MIN_BUFFERS_FOR_CAPTURE`` ``(integer)``
+    This is a read-only control that can be read by the application and
+    used as a hint to determine the number of CAPTURE buffers to pass to
+    REQBUFS. The value is the minimum number of CAPTURE buffers that is
+    necessary for hardware to work.
+
+``V4L2_CID_MIN_BUFFERS_FOR_OUTPUT`` ``(integer)``
+    This is a read-only control that can be read by the application and
+    used as a hint to determine the number of OUTPUT buffers to pass to
+    REQBUFS. The value is the minimum number of OUTPUT buffers that is
+    necessary for hardware to work.
+
+.. _v4l2-alpha-component:
+
+``V4L2_CID_ALPHA_COMPONENT`` ``(integer)``
+    Sets the alpha color component. When a capture device (or capture
+    queue of a mem-to-mem device) produces a frame format that includes
+    an alpha component (e.g.
+    :ref:`packed RGB image formats <pixfmt-rgb>`) and the alpha value
+    is not defined by the device or the mem-to-mem input data this
+    control lets you select the alpha component value of all pixels.
+    When an output device (or output queue of a mem-to-mem device)
+    consumes a frame format that doesn't include an alpha component and
+    the device supports alpha channel processing this control lets you
+    set the alpha component value of all pixels for further processing
+    in the device.
+
+``V4L2_CID_LASTP1``
+    End of the predefined control IDs (currently
+    ``V4L2_CID_ALPHA_COMPONENT`` + 1).
+
+``V4L2_CID_PRIVATE_BASE``
+    ID of the first custom (driver specific) control. Applications
+    depending on particular custom controls should check the driver name
+    and version, see :ref:`querycap`.
+
+Applications can enumerate the available controls with the
+:ref:`VIDIOC_QUERYCTRL` and
+:ref:`VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>` ioctls, get and set a
+control value with the :ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls. Drivers must implement
+``VIDIOC_QUERYCTRL``, ``VIDIOC_G_CTRL`` and ``VIDIOC_S_CTRL`` when the
+device has one or more controls, ``VIDIOC_QUERYMENU`` when it has one or
+more menu type controls.
+
+
+.. _enum_all_controls:

+   The use of ``V4L2_CID_PRIVATE_BASE`` is problematic because different
+   drivers may use the same ``V4L2_CID_PRIVATE_BASE`` ID for different
+   controls. This makes it hard to programmatically set such controls
+   since the meaning of the control with that ID is driver dependent. In
+   order to resolve this drivers use unique IDs and the
+   ``V4L2_CID_PRIVATE_BASE`` IDs are mapped to those unique IDs by the
+   kernel. Consider these ``V4L2_CID_PRIVATE_BASE`` IDs as aliases to
+   the real IDs.
+
+   Many applications today still use the ``V4L2_CID_PRIVATE_BASE`` IDs
+   instead of using :ref:`VIDIOC_QUERYCTRL` with
+   the ``V4L2_CTRL_FLAG_NEXT_CTRL`` flag to enumerate all IDs, so
+   support for ``V4L2_CID_PRIVATE_BASE`` is still around.

+*****************************************************
+Image Cropping, Insertion and Scaling -- the CROP API
+*****************************************************
+
+.. note::
+
+   The CROP API is mostly superseded by the newer :ref:`SELECTION API
+   <selection-api>`. The new API should be preferred in most cases,
+   with the exception of pixel aspect ratio detection, which is
+   implemented by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` and has no
+   equivalent in the SELECTION API. See :ref:`selection-vs-crop` for a
+   comparison of the two APIs.
+
+Some video capture devices can sample a subsection of the picture and
+shrink or enlarge it to an image of arbitrary size. We call these
+abilities cropping and scaling. Some video output devices can scale an
+image up or down and insert it at an arbitrary scan line and horizontal
+offset into a video signal.
+
+Applications can use the following API to select an area in the video
+signal, query the default area and the hardware limits.
+
+.. note::
+
+   Despite their name, the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`,
+   :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP
+   <VIDIOC_G_CROP>` ioctls apply to input as well as output devices.
+
+Scaling requires a source and a target. On a video capture or overlay
+device the source is the video signal, and the cropping ioctls determine
+the area actually sampled. The target are images read by the application
+or overlaid onto the graphics screen. Their size (and position for an
+overlay) is negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls.
+
+On a video output device the source are the images passed in by the
+application, and their size is again negotiated with the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctls, or may be encoded in a compressed video stream. The target is
+the video signal, and the cropping ioctls determine the area where the
+images are inserted.
+
+Source and target rectangles are defined even if the device does not
+support scaling or the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctls. Their size (and position
+where applicable) will be fixed in this case.
+
+.. note::
+
+   All capture and output devices that support the CROP or SELECTION
+   API will also support the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`
+   ioctl.
+
+Cropping Structures
+===================
+
+
+.. _crop-scale:
+
+.. kernel-figure:: crop.svg
+    :alt:    crop.svg
+    :align:  center
+
+    Image Cropping, Insertion and Scaling
+
+    The cropping, insertion and scaling process
+
+
+
+For capture devices the coordinates of the top left corner, width and
+height of the area which can be sampled is given by the ``bounds``
+substructure of the struct :c:type:`v4l2_cropcap` returned
+by the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl. To support a wide
+range of hardware this specification does not define an origin or units.
+However by convention drivers should horizontally count unscaled samples
+relative to 0H (the leading edge of the horizontal sync pulse, see
+:ref:`vbi-hsync`). Vertically ITU-R line numbers of the first field
+(see ITU R-525 line numbering for :ref:`525 lines <vbi-525>` and for
+:ref:`625 lines <vbi-625>`), multiplied by two if the driver
+can capture both fields.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by struct
+:c:type:`v4l2_crop` using the same coordinate system as
+struct :c:type:`v4l2_cropcap`. Applications can use the
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>`
+ioctls to get and set this rectangle. It must lie completely within the
+capture boundaries and the driver may further adjust the requested size
+and/or position according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``defrect`` substructure of struct
+:c:type:`v4l2_cropcap`. The center of this rectangle
+shall align with the center of the active picture area of the video
+signal, and cover what the driver writer considers the complete picture.
+Drivers shall reset the source rectangle to the default when the driver
+is first loaded, but not later.
+
+For output devices these structures and ioctls are used accordingly,
+defining the *target* rectangle where the images will be inserted into
+the video signal.
+
+
+Scaling Adjustments
+===================
+
+Video hardware can have various cropping, insertion and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in horizontal and vertical
+direction. Also it may not support scaling at all. At the same time the
+struct :c:type:`v4l2_crop` rectangle may have to be aligned,
+and both the source and target rectangles may have arbitrary upper and
+lower size limits. In particular the maximum ``width`` and ``height`` in
+struct :c:type:`v4l2_crop` may be smaller than the struct
+:c:type:`v4l2_cropcap`. ``bounds`` area. Therefore, as
+usual, drivers are expected to adjust the requested parameters and
+return the actual values selected.
+
+Applications can change the source or the target rectangle first, as
+they may prefer a particular image size or a certain area in the video
+signal. If the driver has to adjust both to satisfy hardware
+limitations, the last requested rectangle shall take priority, and the
+driver should preferably adjust the opposite one. The
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl however shall not change
+the driver state and therefore only adjust the requested rectangle.
+
+Suppose scaling on a video capture device is restricted to a factor 1:1
+or 2:1 in either direction and the target image size must be a multiple
+of 16 × 16 pixels. The source cropping rectangle is set to defaults,
+which are also the upper limit in this example, of 640 × 400 pixels at
+offset 0, 0. An application requests an image size of 300 × 225 pixels,
+assuming video will be scaled down from the "full picture" accordingly.
+The driver sets the image size to the closest possible values 304 × 224,
+then chooses the cropping rectangle closest to the requested size, that
+is 608 × 224 (224 × 2:1 would exceed the limit 400). The offset 0, 0 is
+still valid, thus unmodified. Given the default cropping rectangle
+reported by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` the application can
+easily propose another offset to center the cropping rectangle.
+
+Now the application may insist on covering an area using a picture
+aspect ratio closer to the original request, so it asks for a cropping
+rectangle of 608 × 456 pixels. The present scaling factors limit
+cropping to 640 × 384, so the driver returns the cropping size 608 × 384
+and adjusts the image size to closest possible 304 × 192.
+
+
+Examples
+========
+
+Source and target rectangles shall remain unchanged across closing and
+reopening a device, such that piping data into or out of a device will
+work without special preparations. More advanced applications should
+ensure the parameters are suitable before starting I/O.
+
+.. note::
+
+   On the next two examples, a video capture device is assumed;
+   change ``V4L2_BUF_TYPE_VIDEO_CAPTURE`` for other types of device.
+

+***********************
+Video Capture Interface
+***********************
+
+Video capture devices sample an analog video signal and store the
+digitized images in memory. Today nearly all devices can capture at full
+25 or 30 frames/second. With this interface applications can control the
+capture process and move images from the driver into user space.
+
+Conventionally V4L2 video capture devices are accessed through character
+device special files named ``/dev/video`` and ``/dev/video0`` to
+``/dev/video63`` with major number 81 and minor numbers 0 to 63.
+``/dev/video`` is typically a symbolic link to the preferred video
+device.
+
+.. note:: The same device file names are used for video output devices.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video capture interface set the
+``V4L2_CAP_VIDEO_CAPTURE`` or ``V4L2_CAP_VIDEO_CAPTURE_MPLANE`` flag in
+the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
+functions they may also support the :ref:`video overlay <overlay>`
+(``V4L2_CAP_VIDEO_OVERLAY``) and the :ref:`raw VBI capture <raw-vbi>`
+(``V4L2_CAP_VBI_CAPTURE``) interface. At least one of the read/write or
+streaming I/O methods must be supported. Tuners and audio inputs are
+optional.
+
+
+Supplemental Functions
+======================
+
+Video capture devices shall support :ref:`audio input <audio>`,
+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` ioctls must be supported by all video
+capture devices.
+
+
+Image Format Negotiation
+========================
+
+The result of a capture operation is determined by cropping and image
+format parameters. The former select an area of the video picture to
+capture, the latter how images are stored in memory, i. e. in RGB or YUV
+format, the number of bits per pixel or width and height. Together they
+also define how images are scaled in the process.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications ensure
+they really get what they want, including cropping and scaling.
+
+Cropping initialization at minimum requires to reset the parameters to
+defaults. An example is given in :ref:`crop`.
+
+To query the current image format applications set the ``type`` field of
+a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member of the ``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_pix_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers may adjust the
+parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+does.
+
+Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
+can be used to learn about hardware limitations without disabling I/O or
+possibly time consuming hardware preparations.
+
+The contents of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_pix_format_mplane` are
+discussed in :ref:`pixfmt`. See also the specification of the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
+details. Video capture devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
+requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
+
+
+Reading Images
+==============
+
+A video capture device may support the :ref:`read() function <func-read>`
+and/or streaming (:ref:`memory mapping <func-mmap>` or
+:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

+Event Interface
+***************
+
+The V4L2 event interface provides a means for a user to get immediately
+notified on certain conditions taking place on a device. This might
+include start of frame or loss of signal events, for example. Changes in
+the value or state of a V4L2 control can also be reported through
+events.
+
+To receive events, the events the user is interested in first must be
+subscribed using the
+:ref:`VIDIOC_SUBSCRIBE_EVENT` ioctl. Once
+an event is subscribed, the events of subscribed types are dequeueable
+using the :ref:`VIDIOC_DQEVENT` ioctl. Events may be
+unsubscribed using VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event
+type V4L2_EVENT_ALL may be used to unsubscribe all the events the
+driver supports.
+
+The event subscriptions and event queues are specific to file handles.
+Subscribing an event on one file handle does not affect other file
+handles.
+
+The information on dequeueable events is obtained by using select or
+poll system calls on video devices. The V4L2 events use POLLPRI events
+on poll system call and exceptions on select system call.
+
+Starting with kernel 3.1 certain guarantees can be given with regards to
+events:
+
+1. Each subscribed event has its own internal dedicated event queue.
+   This means that flooding of one event type will not interfere with
+   other event types.
+
+2. If the internal event queue for a particular subscribed event becomes
+   full, then the oldest event in that queue will be dropped.
+
+3. Where applicable, certain event types can ensure that the payload of
+   the oldest event that is about to be dropped will be merged with the
+   payload of the next oldest event. Thus ensuring that no information
+   is lost, but only an intermediate step leading up to that
+   information. See the documentation for the event you want to
+   subscribe to whether this is applicable for that event or not.

+********************************
+Video Memory-To-Memory Interface
+********************************
+
+A V4L2 memory-to-memory device can compress, decompress, transform, or
+otherwise convert video data from one format into another format, in memory.
+Such memory-to-memory devices set the ``V4L2_CAP_VIDEO_M2M`` or
+``V4L2_CAP_VIDEO_M2M_MPLANE`` capability. Examples of memory-to-memory
+devices are codecs, scalers, deinterlacers or format converters (i.e.
+converting from YUV to RGB).
+
+A memory-to-memory video node acts just like a normal video node, but it
+supports both output (sending frames from memory to the hardware)
+and capture (receiving the processed frames from the hardware into
+memory) stream I/O. An application will have to setup the stream I/O for
+both sides and finally call :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+for both capture and output to start the hardware.
+
+Memory-to-memory devices function as a shared resource: you can
+open the video node multiple times, each application setting up their
+own properties that are local to the file handle, and each can use
+it independently from the others. The driver will arbitrate access to
+the hardware and reprogram it whenever another file handler gets access.
+This is different from the usual video node behavior where the video
+properties are global to the device (i.e. changing something through one
+file handle is visible through another file handle).
+
+One of the most common memory-to-memory device is the codec. Codecs
+are more complicated than most and require additional setup for
+their codec parameters. This is done through codec controls.
+See :ref:`mpeg-controls`. More details on how to use codec memory-to-memory
+devices are given in the following sections.

+******************
+Metadata Interface
+******************
+
+Metadata refers to any non-image data that supplements video frames with
+additional information. This may include statistics computed over the image,
+frame capture parameters supplied by the image source or device specific
+parameters for specifying how the device processes images. This interface is
+intended for transfer of metadata between the userspace and the hardware and
+control of that operation.
+
+The metadata interface is implemented on video device nodes. The device can be
+dedicated to metadata or can support both video and metadata as specified in its
+reported capabilities.
+
+Querying Capabilities
+=====================
+
+Device nodes supporting the metadata capture interface set the
+``V4L2_CAP_META_CAPTURE`` flag in the ``device_caps`` field of the
+:c:type:`v4l2_capability` structure returned by the :c:func:`VIDIOC_QUERYCAP`
+ioctl. That flag means the device can capture metadata to memory. Similarly,
+device nodes supporting metadata output interface set the
+``V4L2_CAP_META_OUTPUT`` flag in the ``device_caps`` field of
+:c:type:`v4l2_capability` structure. That flag means the device can read
+metadata from memory.
+
+At least one of the read/write or streaming I/O methods must be supported.
+
+
+Data Format Negotiation
+=======================
+
+The metadata device uses the :ref:`format` ioctls to select the capture format.
+The metadata buffer content format is bound to that selected format. In addition
+to the basic :ref:`format` ioctls, the :c:func:`VIDIOC_ENUM_FMT` ioctl must be
+supported as well.
+
+To use the :ref:`format` ioctls applications set the ``type`` field of the
+:c:type:`v4l2_format` structure to ``V4L2_BUF_TYPE_META_CAPTURE`` or to
+``V4L2_BUF_TYPE_META_OUTPUT`` and use the :c:type:`v4l2_meta_format` ``meta``
+member of the ``fmt`` union as needed per the desired operation. Both drivers
+and applications must set the remainder of the :c:type:`v4l2_format` structure
+to 0.

+outgoing video signal. Applications can set up such an overlay using
+this interface, which borrows structures and ioctls of the
+:ref:`Video Overlay <overlay>` interface.
+
+The OSD function is accessible through the same character special file
+as the :ref:`Video Output <capture>` function.
+
+.. note::
+
+   The default function of such a ``/dev/video`` device is video
+   capturing or output. The OSD function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the *Video Output Overlay* interface set the
+``V4L2_CAP_VIDEO_OUTPUT_OVERLAY`` flag in the ``capabilities`` field of
+struct :c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Framebuffer
+===========
+
+Contrary to the *Video Overlay* interface the framebuffer is normally
+implemented on the TV card and not the graphics card. On Linux it is
+accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
+applications can find the corresponding framebuffer device by calling
+the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` ioctl. It returns, amongst
+other information, the physical address of the framebuffer in the
+``base`` field of struct :c:type:`v4l2_framebuffer`.
+The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
+address in the ``smem_start`` field of struct
+struct :c:type:`fb_fix_screeninfo`. The ``FBIOGET_FSCREENINFO``
+ioctl and struct :c:type:`fb_fix_screeninfo` are defined in
+the ``linux/fb.h`` header file.
+
+The width and height of the framebuffer depends on the current video
+standard. A V4L2 driver may reject attempts to change the video standard
+(or any other ioctl which would imply a framebuffer size change) with an
+``EBUSY`` error code until all applications closed the framebuffer device.
+
+Example: Finding a framebuffer device for OSD
+---------------------------------------------
+
+.. code-block:: c
+
+    #include <linux/fb.h>
+
+    struct v4l2_framebuffer fbuf;
+    unsigned int i;
+    int fb_fd;
+
+    if (-1 == ioctl(fd, VIDIOC_G_FBUF, &fbuf)) {
+	perror("VIDIOC_G_FBUF");
+	exit(EXIT_FAILURE);
+    }
+
+    for (i = 0; i < 30; i++) {
+	char dev_name[16];
+	struct fb_fix_screeninfo si;
+
+	snprintf(dev_name, sizeof(dev_name), "/dev/fb%u", i);
+
+	fb_fd = open(dev_name, O_RDWR);
+	if (-1 == fb_fd) {
+	    switch (errno) {
+	    case ENOENT: /* no such file */
+	    case ENXIO:  /* no driver */
+		continue;
+
+	    default:
+		perror("open");
+		exit(EXIT_FAILURE);
+	    }
+	}
+
+	if (0 == ioctl(fb_fd, FBIOGET_FSCREENINFO, &si)) {
+	    if (si.smem_start == (unsigned long)fbuf.base)
+		break;
+	} else {
+	    /* Apparently not a framebuffer device. */
+	}
+
+	close(fb_fd);
+	fb_fd = -1;
+    }
+
+    /* fb_fd is the file descriptor of the framebuffer device
+       for the video output overlay, or -1 if no device was found. */
+
+
+Overlay Window and Scaling
+==========================
+
+The overlay is controlled by source and target rectangles. The source
+rectangle selects a subsection of the framebuffer image to be overlaid,
+the target rectangle an area in the outgoing video signal where the
+image will appear. Drivers may or may not support scaling, and arbitrary
+sizes and positions of these rectangles. Further drivers may support any
+(or none) of the clipping/blending methods defined for the
+:ref:`Video Overlay <overlay>` interface.
+
+A struct :c:type:`v4l2_window` defines the size of the
+source rectangle, its position in the framebuffer and the
+clipping/blending method to be used for the overlay. To get the current
+parameters applications set the ``type`` field of a struct
+:c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+struct :c:type:`v4l2_window` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the source rectangle applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY``, initialize the ``win``
+substructure and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+The driver adjusts the parameters against hardware limits and returns
+the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+A struct :c:type:`v4l2_crop` defines the size and position
+of the target rectangle. The scaling factor of the overlay is implied by
+the width and height given in struct :c:type:`v4l2_window`
+and struct :c:type:`v4l2_crop`. The cropping API applies to
+*Video Output* and *Video Output Overlay* devices in the same way as to
+*Video Capture* and *Video Overlay* devices, merely reversing the
+direction of the data flow. For more information see :ref:`crop`.
+
+
+Enabling Overlay
+================
+
+There is no V4L2 ioctl to enable or disable the overlay, however the
+framebuffer interface of the driver may support the ``FBIOBLANK`` ioctl.

+**********************
+Video Output Interface
+**********************
+
+Video output devices encode stills or image sequences as analog video
+signal. With this interface applications can control the encoding
+process and move images from user space to the driver.
+
+Conventionally V4L2 video output devices are accessed through character
+device special files named ``/dev/video`` and ``/dev/video0`` to
+``/dev/video63`` with major number 81 and minor numbers 0 to 63.
+``/dev/video`` is typically a symbolic link to the preferred video
+device.
+
+.. note:: The same device file names are used also for video capture devices.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video output interface set the
+``V4L2_CAP_VIDEO_OUTPUT`` or ``V4L2_CAP_VIDEO_OUTPUT_MPLANE`` flag in
+the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
+functions they may also support the :ref:`raw VBI output <raw-vbi>`
+(``V4L2_CAP_VBI_OUTPUT``) interface. At least one of the read/write or
+streaming I/O methods must be supported. Modulators and audio outputs
+are optional.
+
+
+Supplemental Functions
+======================
+
+Video output devices shall support :ref:`audio output <audio>`,
+:ref:`modulator <tuner>`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video output <video>` ioctls must be supported by all video
+output devices.
+
+
+Image Format Negotiation
+========================
+
+The output is determined by cropping and image format parameters. The
+former select an area of the video picture where the image will appear,
+the latter how images are stored in memory, i. e. in RGB or YUV format,
+the number of bits per pixel or width and height. Together they also
+define how images are scaled in the process.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then writing
+to it as if it was a plain file. Well written V4L2 applications ensure
+they really get what they want, including cropping and scaling.
+
+Cropping initialization at minimum requires to reset the parameters to
+defaults. An example is given in :ref:`crop`.
+
+To query the current image format applications set the ``type`` field of
+a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` or ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``
+and call the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer
+to this structure. Drivers fill the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member of the ``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_pix_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers may adjust the
+parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+does.
+
+Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
+can be used to learn about hardware limitations without disabling I/O or
+possibly time consuming hardware preparations.
+
+The contents of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_pix_format_mplane` are
+discussed in :ref:`pixfmt`. See also the specification of the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
+details. Video output devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
+requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
+
+
+Writing Images
+==============
+
+A video output device may support the :ref:`write() function <rw>`
+and/or streaming (:ref:`memory mapping <mmap>` or
+:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

+***********************
+Video Overlay Interface
+***********************
+
+**Also known as Framebuffer Overlay or Previewing.**
+
+Video overlay devices have the ability to genlock (TV-)video into the
+(VGA-)video signal of a graphics card, or to store captured images
+directly in video memory of a graphics card, typically with clipping.
+This can be considerable more efficient than capturing images and
+displaying them by other means. In the old days when only nuclear power
+plants needed cooling towers this used to be the only way to put live
+video into a window.
+
+Video overlay devices are accessed through the same character special
+files as :ref:`video capture <capture>` devices.
+
+.. note::
+
+   The default function of a ``/dev/video`` device is video
+   capturing. The overlay function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The driver may support simultaneous overlay and capturing using the
+read/write and streaming I/O methods. If so, operation at the nominal
+frame rate of the video standard is not guaranteed. Frames may be
+directed away from overlay to capture, or one field may be used for
+overlay and the other for capture if the capture parameters permit this.
+
+Applications should use different file descriptors for capturing and
+overlay. This must be supported by all drivers capable of simultaneous
+capturing and overlay. Optionally these drivers may also permit
+capturing and overlay with a single file descriptor for compatibility
+with V4L and earlier versions of V4L2. [#f1]_
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video overlay interface set the
+``V4L2_CAP_VIDEO_OVERLAY`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. The overlay I/O
+method specified below must be supported. Tuners and audio inputs are
+optional.
+
+
+Supplemental Functions
+======================
+
+Video overlay devices shall support :ref:`audio input <audio>`,
+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` and :ref:`video standard <standard>`
+ioctls must be supported by all video overlay devices.
+
+
+Setup
+=====
+
+Before overlay can commence applications must program the driver with
+frame buffer parameters, namely the address and size of the frame buffer
+and the image format, for example RGB 5:6:5. The
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls are available to get and
+set these parameters, respectively. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is
+privileged because it allows to set up DMA into physical memory,
+bypassing the memory protection mechanisms of the kernel. Only the
+superuser can change the frame buffer address and size. Users are not
+supposed to run TV applications as root or with SUID bit set. A small
+helper application with suitable privileges should query the graphics
+system and program the V4L2 driver at the appropriate time.
+
+Some devices add the video overlay to the output signal of the graphics
+card. In this case the frame buffer is not modified by the video device,
+and the frame buffer address and pixel format are not needed by the
+driver. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is not privileged. An application
+can check for this type of device by calling the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl.
+
+A driver may support any (or none) of five clipping/blending methods:
+
+1. Chroma-keying displays the overlaid image only where pixels in the
+   primary graphics surface assume a certain color.
+
+2. A bitmap can be specified where each bit corresponds to a pixel in
+   the overlaid image. When the bit is set, the corresponding video
+   pixel is displayed, otherwise a pixel of the graphics surface.
+
+3. A list of clipping rectangles can be specified. In these regions *no*
+   video is displayed, so the graphics surface can be seen here.
+
+4. The framebuffer has an alpha channel that can be used to clip or
+   blend the framebuffer with the video.
+
+5. A global alpha value can be specified to blend the framebuffer
+   contents with video images.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and frame buffer formats, the format requested
+first takes precedence. The attempt to capture
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) or overlay
+(:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters..
+
+
+Overlay Window
+==============
+
+The overlaid image is determined by cropping and overlay window
+parameters. The former select an area of the video picture to capture,
+the latter how images are overlaid and clipped. Cropping initialization
+at minimum requires to reset the parameters to defaults. An example is
+given in :ref:`crop`.
+
+The overlay window is described by a struct
+:c:type:`v4l2_window`. It defines the size of the image,
+its position over the graphics surface and the clipping to be applied.
+To get the current parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+struct :c:type:`v4l2_window` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the overlay window applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY``, initialize the ``win`` substructure and
+call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. The driver
+adjusts the parameters against hardware limits and returns the actual
+parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+The scaling factor of the overlaid image is implied by the width and
+height given in struct :c:type:`v4l2_window` and the size
+of the cropping rectangle. For more information see :ref:`crop`.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and window sizes, the size requested first
+takes precedence. The attempt to capture or overlay as well
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters.
+
+
+.. c:type:: v4l2_window
+
+struct v4l2_window
+------------------
+
+``struct v4l2_rect w``
+    Size and position of the window relative to the top, left corner of
+    the frame buffer defined with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The window can extend the
+    frame buffer width and height, the ``x`` and ``y`` coordinates can
+    be negative, and it can lie completely outside the frame buffer. The
+    driver clips the window accordingly, or if that is not possible,
+    modifies its size and/or position.
+
+``enum v4l2_field field``
+    Applications set this field to determine which video field shall be
+    overlaid, typically one of ``V4L2_FIELD_ANY`` (0),
+    ``V4L2_FIELD_TOP``, ``V4L2_FIELD_BOTTOM`` or
+    ``V4L2_FIELD_INTERLACED``. Drivers may have to choose a different
+    field order and return the actual setting here.
+
+``__u32 chromakey``
+    When chroma-keying has been negotiated with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` applications set this field
+    to the desired pixel value for the chroma key. The format is the
+    same as the pixel format of the framebuffer (struct
+    :c:type:`v4l2_framebuffer` ``fmt.pixelformat``
+    field), with bytes in host order. E. g. for
+    :ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR32>` the value should
+    be 0xRRGGBB on a little endian, 0xBBGGRR on a big endian host.
+
+``struct v4l2_clip * clips``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to an array of clipping
+    rectangles.
+
+    Like the window coordinates w, clipping rectangles are defined
+    relative to the top, left corner of the frame buffer. However
+    clipping rectangles must not extend the frame buffer width and
+    height, and they must not overlap. If possible applications
+    should merge adjacent rectangles. Whether this must create
+    x-y or y-x bands, or the order of rectangles, is not defined. When
+    clip lists are not supported the driver ignores this field. Its
+    contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+    are undefined.
+
+``__u32 clipcount``
+    When the application set the ``clips`` field, this field must
+    contain the number of clipping rectangles in the list. When clip
+    lists are not supported the driver ignores this field, its contents
+    after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are undefined. When clip lists are
+    supported but no clipping is desired this field must be set to zero.
+
+``void * bitmap``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to a clipping bit mask.
+
+It must be of the same size as the window, ``w.width`` and ``w.height``.
+Each bit corresponds to a pixel in the overlaid image, which is
+displayed only when the bit is *set*. Pixel coordinates translate to
+bits like:
+
+
+.. code-block:: c
+
+    ((__u8 *) bitmap)[w.width * y + x / 8] & (1 << (x & 7))
+
+where ``0`` ≤ x < ``w.width`` and ``0`` ≤ y <``w.height``. [#f2]_
+
+When a clipping bit mask is not supported the driver ignores this field,
+its contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are
+undefined. When a bit mask is supported but no clipping is desired this
+field must be set to ``NULL``.
+
+Applications need not create a clip list or bit mask. When they pass
+both, or despite negotiating chroma-keying, the results are undefined.
+Regardless of the chosen method, the clipping abilities of the hardware
+may be limited in quantity or quality. The results when these limits are
+exceeded are undefined. [#f3]_
+
+``__u8 global_alpha``
+    The global alpha value used to blend the framebuffer with video
+    images, if global alpha blending has been negotiated
+    (``V4L2_FBUF_FLAG_GLOBAL_ALPHA``, see
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`,
+    :ref:`framebuffer-flags`).
+
+.. note::
+
+   This field was added in Linux 2.6.23, extending the
+   structure. However the :ref:`VIDIOC_[G|S|TRY]_FMT <VIDIOC_G_FMT>`
+   ioctls, which take a pointer to a :c:type:`v4l2_format`
+   parent structure with padding bytes at the end, are not affected.
+
+
+.. c:type:: v4l2_clip
+
+struct v4l2_clip [#f4]_
+-----------------------
+
+``struct v4l2_rect c``
+    Coordinates of the clipping rectangle, relative to the top, left
+    corner of the frame buffer. Only window pixels *outside* all
+    clipping rectangles are displayed.
+
+``struct v4l2_clip * next``
+    Pointer to the next clipping rectangle, ``NULL`` when this is the last
+    rectangle. Drivers ignore this field, it cannot be used to pass a
+    linked list of clipping rectangles.
+
+
+.. c:type:: v4l2_rect
+
+struct v4l2_rect
+----------------
+
+``__s32 left``
+    Horizontal offset of the top, left corner of the rectangle, in
+    pixels.
+
+``__s32 top``
+    Vertical offset of the top, left corner of the rectangle, in pixels.
+    Offsets increase to the right and down.
+
+``__u32 width``
+    Width of the rectangle, in pixels.
+
+``__u32 height``
+    Height of the rectangle, in pixels.
+
+
+Enabling Overlay
+================
+
+To start or stop the frame buffer overlay applications call the
+:ref:`VIDIOC_OVERLAY` ioctl.
+
+.. [#f1]
+   A common application of two file descriptors is the XFree86
+   :ref:`Xv/V4L <xvideo>` interface driver and a V4L2 application.
+   While the X server controls video overlay, the application can take
+   advantage of memory mapping and DMA.
+
+   In the opinion of the designers of this API, no driver writer taking
+   the efforts to support simultaneous capturing and overlay will
+   restrict this ability by requiring a single file descriptor, as in
+   V4L and earlier versions of V4L2. Making this optional means
+   applications depending on two file descriptors need backup routines
+   to be compatible with all drivers, which is considerable more work
+   than using two fds in applications which do not. Also two fd's fit
+   the general concept of one file descriptor for each logical stream.
+   Hence as a complexity trade-off drivers *must* support two file
+   descriptors and *may* support single fd operation.
+
+.. [#f2]
+   Should we require ``w.width`` to be a multiple of eight?
+
+.. [#f3]
+   When the image is written into frame buffer memory it will be
+   undesirable if the driver clips out less pixels than expected,
+   because the application and graphics system are not aware these
+   regions need to be refreshed. The driver should clip out more pixels
+   or not write the image at all.
+
+.. [#f4]
+   The X Window system defines "regions" which are vectors of ``struct

+Radio Interface
+***************
+
+This interface is intended for AM and FM (analog) radio receivers and
+transmitters.
+
+Conventionally V4L2 radio devices are accessed through character device
+special files named ``/dev/radio`` and ``/dev/radio0`` to
+``/dev/radio63`` with major number 81 and minor numbers 64 to 127.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the radio interface set the ``V4L2_CAP_RADIO`` and
+``V4L2_CAP_TUNER`` or ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Other combinations of
+capability flags are reserved for future extensions.
+
+
+Supplemental Functions
+======================
+
+Radio devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner or modulator <tuner>` ioctls.
+
+They do not support the video input or output, audio input or output,
+video standard, cropping and scaling, compression and streaming
+parameter, or overlay ioctls. All other ioctls and I/O methods are
+reserved for future extensions.
+
+
+Programming
+===========
+
+Radio devices may have a couple audio controls (as discussed in
+:ref:`control`) such as a volume control, possibly custom controls.
+Further all radio devices have one tuner or modulator (these are
+discussed in :ref:`tuner`) with index number zero to select the radio
+frequency and to determine if a monaural or FM stereo program is
+received/emitted. Drivers switch automatically between AM and FM
+depending on the selected frequency. The
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` or
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl reports the
+supported frequency range.

+**********************
+Raw VBI Data Interface
+**********************
+
+VBI is an abbreviation of Vertical Blanking Interval, a gap in the
+sequence of lines of an analog video signal. During VBI no picture
+information is transmitted, allowing some time while the electron beam
+of a cathode ray tube TV returns to the top of the screen. Using an
+oscilloscope you will find here the vertical synchronization pulses and
+short data packages ASK modulated [#f1]_ onto the video signal. These are
+transmissions of services such as Teletext or Closed Caption.
+
+Subject of this interface type is raw VBI data, as sampled off a video
+signal, or to be added to a signal for output. The data format is
+similar to uncompressed video images, a number of lines times a number
+of samples per line, we call this a VBI image.
+
+Conventionally V4L2 VBI devices are accessed through character device
+special files named ``/dev/vbi`` and ``/dev/vbi0`` to ``/dev/vbi31``
+with major number 81 and minor numbers 224 to 255. ``/dev/vbi`` is
+typically a symbolic link to the preferred VBI device. This convention
+applies to both input and output devices.
+
+To address the problems of finding related video and VBI devices VBI
+capturing and output is also available as device function under
+``/dev/video``. To capture or output raw VBI data with these devices
+applications must call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+Accessed as ``/dev/vbi``, raw VBI capturing or output is the default
+device function.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the raw VBI capturing or output API set the
+``V4L2_CAP_VBI_CAPTURE`` or ``V4L2_CAP_VBI_OUTPUT`` flags, respectively,
+in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous I/O methods must be supported. VBI
+devices may or may not have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+VBI devices shall support :ref:`video input or output <video>`,
+:ref:`tuner or modulator <tuner>`, and :ref:`controls <control>`
+ioctls as needed. The :ref:`video standard <standard>` ioctls provide
+information vital to program a VBI device, therefore must be supported.
+
+
+Raw VBI Format Negotiation
+==========================
+
+Raw VBI sampling abilities can vary, in particular the sampling
+frequency. To properly interpret the data V4L2 specifies an ioctl to
+query the sampling parameters. Moreover, to allow for some flexibility
+applications can also suggest different parameters.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications should
+always ensure they really get what they want, requesting reasonable
+parameters and then checking if the actual parameters are suitable.
+
+To query the current raw VBI capture parameters applications set the
+``type`` field of a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VBI_CAPTURE`` or ``V4L2_BUF_TYPE_VBI_OUTPUT``, and call
+the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:c:type:`v4l2_vbi_format` ``vbi`` member of the
+``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_vbi_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers return an ``EINVAL`` error
+code only when the given parameters are ambiguous, otherwise they modify
+the parameters according to the hardware capabilities and return the
+actual parameters. When the driver allocates resources at this point, it
+may return an ``EBUSY`` error code to indicate the returned parameters are
+valid but the required resources are currently not available. That may
+happen for instance when the video and VBI areas to capture would
+overlap, or when the driver supports multiple opens and another process
+already requested VBI capturing or output. Anyway, applications must
+expect other resource allocation points which may return ``EBUSY``, at the
+:ref:`VIDIOC_STREAMON` ioctl and the first :ref:`read() <func-read>`
+, :ref:`write() <func-write>` and :ref:`select() <func-select>` calls.
+
+VBI devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all requests
+and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.

+	i. e. each sample consists of 8 bits with lower values oriented
+	towards the black level. Do not assume any other correlation of
+	values with the signal level. For example, the MSB does not
+	necessarily indicate if the signal is 'high' or 'low' because 128

+	the sample format by software.
+    * - __u32
+      - ``start``\ [#f2]_
+      - This is the scanning system line number associated with the first

+	values. The ``V4L2_VBI_ITU_525_F1_START``,
+	``V4L2_VBI_ITU_525_F2_START``, ``V4L2_VBI_ITU_625_F1_START`` and
+	``V4L2_VBI_ITU_625_F2_START`` defines give the start line numbers
+	for each field for each 525 or 625 line format as a convenience.
+	Don't forget that ITU line numbering starts at 1, not 0. VBI input

+      - ``count``\ [#f2]_
+      - The number of lines in the first and second field image,

+
+	Drivers should be as flexibility as possible. For example, it may
+	be possible to extend or move the VBI capture window down to the
+	picture area, implementing a 'full field mode' to capture data
+	service transmissions embedded in the picture.
+
+	An application can set the first or second ``count`` value to zero
+	if no data is required from the respective field; ``count``\ [1]
+	if the scanning system is progressive, i. e. not interlaced. The
+	corresponding start value shall be ignored by the application and
+	driver. Anyway, drivers may not support single field capturing and
+	return both count values non-zero.
+
+	Both ``count`` values set to zero, or line numbers are outside the
+	bounds depicted\ [#f4]_, or a field image covering lines of two
+	fields, are invalid and shall not be returned by the driver.
+
+	To initialize the ``start`` and ``count`` fields, applications
+	must first determine the current video standard selection. The
+	:ref:`v4l2_std_id <v4l2-std-id>` or the ``framelines`` field
+	of struct :c:type:`v4l2_standard` can be evaluated
+	for this purpose.
+    * - __u32
+      - ``flags``
+      - See :ref:`vbifmt-flags` below. Currently only drivers set flags,
+	applications must set this field to zero.
+    * - __u32
+      - ``reserved``\ [#f2]_
+      - This array is reserved for future extensions. Drivers and

+
+    * - ``V4L2_VBI_UNSYNC``
+      - 0x0001
+      - This flag indicates hardware which does not properly distinguish
+	between fields. Normally the VBI image stores the first field
+	(lower scanning line numbers) first in memory. This may be a top
+	or bottom field depending on the video standard. When this flag is
+	set the first or second field may be stored first, however the
+	fields are still in correct temporal order with the older field
+	first in memory. [#f3]_
+    * - ``V4L2_VBI_INTERLACED``
+      - 0x0002
+      - By default the two field images will be passed sequentially; all
+	lines of the first field followed by all lines of the second field
+	(compare :ref:`field-order` ``V4L2_FIELD_SEQ_TB`` and
+	``V4L2_FIELD_SEQ_BT``, whether the top or bottom field is first in
+	memory depends on the video standard). When this flag is set, the
+	two fields are interlaced (cf. ``V4L2_FIELD_INTERLACED``). The
+	first line of the first field followed by the first line of the
+	second field, then the two second lines, and so on. Such a layout
+	may be necessary when the hardware has been programmed to capture
+	or output interlaced video images and is unable to separate the
+	fields for VBI capturing at the same time. For simplicity setting
+	this flag implies that both ``count`` values are equal and
+	non-zero.

+
+Remember the VBI image format depends on the selected video standard,
+therefore the application must choose a new standard or query the
+current standard first. Attempts to read or write data ahead of format
+negotiation, or after switching the video standard which may invalidate
+the negotiated VBI parameters, should be refused by the driver. A format
+change during active I/O is not permitted.
+
+
+Reading and writing VBI images
+==============================
+
+To assure synchronization with the field number and easier
+implementation, the smallest unit of data passed at a time is one frame,
+consisting of two fields of VBI images immediately following in memory.
+
+The total size of a frame computes as follows:
+
+
+.. code-block:: c
+
+    (count[0] + count[1]) * samples_per_line * sample size in bytes
+
+The sample size is most likely always one byte, applications must check
+the ``sample_format`` field though, to function properly with other
+drivers.
+
+A VBI device may support :ref:`read/write <rw>` and/or streaming
+(:ref:`memory mapping <mmap>` or :ref:`user pointer <userp>`) I/O.
+The latter bears the possibility of synchronizing video and VBI data by
+using buffer timestamps.
+
+Remember the :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` ioctl and the
+first :ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call can be resource allocation
+points returning an ``EBUSY`` error code if the required hardware resources
+are temporarily unavailable, for example the device is already in use by
+another process.
+
+.. [#f1]
+   ASK: Amplitude-Shift Keying. A high signal level represents a '1'
+   bit, a low level a '0' bit.
+
+.. [#f2]
+   A few devices may be unable to sample VBI data at all but can extend
+   the video capture window to the VBI region.
+
+.. [#f3]
+   Most VBI services transmit on both fields, but some have different
+   semantics depending on the field number. These cannot be reliable
+   decoded or encoded when ``V4L2_VBI_UNSYNC`` is set.
+
+.. [#f4]
+   The valid values ar shown at :ref:`vbi-525` and :ref:`vbi-625`.

+RDS Interface
+*************
+
+The Radio Data System transmits supplementary information in binary
+format, for example the station name or travel information, on an
+inaudible audio subcarrier of a radio program. This interface is aimed
+at devices capable of receiving and/or transmitting RDS information.
+
+For more information see the core RDS standard :ref:`iec62106` and the
+RBDS standard :ref:`nrsc4`.
+
+.. note::
+
+   Note that the RBDS standard as is used in the USA is almost
+   identical to the RDS standard. Any RDS decoder/encoder can also handle
+   RBDS. Only some of the fields have slightly different meanings. See the
+   RBDS standard for more information.
+
+The RBDS standard also specifies support for MMBS (Modified Mobile
+Search). This is a proprietary format which seems to be discontinued.
+The RDS interface does not support this format. Should support for MMBS
+(or the so-called 'E blocks' in general) be needed, then please contact
+the linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the RDS capturing API set the
+``V4L2_CAP_RDS_CAPTURE`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any tuner that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct :c:type:`v4l2_tuner`. If the
+driver only passes RDS blocks without interpreting the data the
+``V4L2_TUNER_CAP_RDS_BLOCK_IO`` flag has to be set, see
+:ref:`Reading RDS data <reading-rds-data>`. For future use the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` has also been defined. However, a driver
+for a radio tuner with this capability does not yet exist, so if you are
+planning to write such a driver you should discuss this on the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+Whether an RDS signal is present can be detected by looking at the
+``rxsubchans`` field of struct :c:type:`v4l2_tuner`: the
+``V4L2_TUNER_SUB_RDS`` will be set if RDS data was detected.
+
+Devices supporting the RDS output API set the ``V4L2_CAP_RDS_OUTPUT``
+flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any modulator that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct
+:c:type:`v4l2_modulator`. In order to enable the RDS
+transmission one must set the ``V4L2_TUNER_SUB_RDS`` bit in the
+``txsubchans`` field of struct
+:c:type:`v4l2_modulator`. If the driver only passes RDS
+blocks without interpreting the data the ``V4L2_TUNER_CAP_RDS_BLOCK_IO``
+flag has to be set. If the tuner is capable of handling RDS entities
+like program identification codes and radio text, the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` should be set, see
+:ref:`Writing RDS data <writing-rds-data>` and

+Software Defined Radio Interface (SDR)
+**************************************
+
+SDR is an abbreviation of Software Defined Radio, the radio device which
+uses application software for modulation or demodulation. This interface
+is intended for controlling and data streaming of such devices.
+
+SDR devices are accessed through character device special files named
+``/dev/swradio0`` to ``/dev/swradio255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the SDR receiver interface set the
+``V4L2_CAP_SDR_CAPTURE`` and ``V4L2_CAP_TUNER`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Analog to Digital Converter (ADC), which is a mandatory
+element for the SDR receiver.
+
+Devices supporting the SDR transmitter interface set the
+``V4L2_CAP_SDR_OUTPUT`` and ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Digital to Analog Converter (DAC), which is a mandatory
+element for the SDR transmitter.
+
+At least one of the read/write, streaming or asynchronous I/O methods
+must be supported.
+
+
+Supplemental Functions
+======================
+
+SDR devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner` ioctls. Tuner ioctls are used for setting the
+ADC/DAC sampling rate (sampling frequency) and the possible radio
+frequency (RF).
+
+The ``V4L2_TUNER_SDR`` tuner type is used for setting SDR device ADC/DAC
+frequency, and the ``V4L2_TUNER_RF`` tuner type is used for setting
+radio frequency. The tuner index of the RF tuner (if any) must always
+follow the SDR tuner index. Normally the SDR tuner is #0 and the RF
+tuner is #1.
+
+The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl is
+not supported.
+
+
+Data Format Negotiation
+=======================
+
+The SDR device uses the :ref:`format` ioctls to select the
+capture and output format. Both the sampling resolution and the data
+streaming format are bound to that selectable format. In addition to the
+basic :ref:`format` ioctls, the
+:ref:`VIDIOC_ENUM_FMT` ioctl must be supported as
+well.
+
+To use the :ref:`format` ioctls applications set the ``type``
+field of a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_SDR_CAPTURE`` or ``V4L2_BUF_TYPE_SDR_OUTPUT`` and use
+the struct :c:type:`v4l2_sdr_format` ``sdr`` member
+of the ``fmt`` union as needed per the desired operation. Currently
+there is two fields, ``pixelformat`` and ``buffersize``, of struct
+struct :c:type:`v4l2_sdr_format` which are used.
+Content of the ``pixelformat`` is V4L2 FourCC code of the data format.
+The ``buffersize`` field is maximum buffer size in bytes required for
+data transfer, set by the driver in order to inform application.

+*************************
+Sliced VBI Data Interface
+*************************
+
+VBI stands for Vertical Blanking Interval, a gap in the sequence of
+lines of an analog video signal. During VBI no picture information is
+transmitted, allowing some time while the electron beam of a cathode ray
+tube TV returns to the top of the screen.
+
+Sliced VBI devices use hardware to demodulate data transmitted in the
+VBI. V4L2 drivers shall *not* do this by software, see also the
+:ref:`raw VBI interface <raw-vbi>`. The data is passed as short
+packets of fixed size, covering one scan line each. The number of
+packets per video frame is variable.
+
+Sliced VBI capture and output devices are accessed through the same
+character special files as raw VBI devices. When a driver supports both
+interfaces, the default function of a ``/dev/vbi`` device is *raw* VBI
+capturing or output, and the sliced VBI function is only available after
+calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl as defined
+below. Likewise a ``/dev/video`` device may support the sliced VBI API,
+however the default function here is video capturing or output.
+Different file descriptors must be used to pass raw and sliced VBI data
+simultaneously, if this is supported by the driver.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the sliced VBI capturing or output API set the
+``V4L2_CAP_SLICED_VBI_CAPTURE`` or ``V4L2_CAP_SLICED_VBI_OUTPUT`` flag
+respectively, in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous :ref:`I/O methods <io>` must be
+supported. Sliced VBI devices may have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+Sliced VBI devices shall support :ref:`video input or output <video>`
+and :ref:`tuner or modulator <tuner>` ioctls if they have these
+capabilities, and they may support :ref:`control` ioctls.
+The :ref:`video standard <standard>` ioctls provide information vital
+to program a sliced VBI device, therefore must be supported.
+
+
+.. _sliced-vbi-format-negotitation:
+
+Sliced VBI Format Negotiation
+=============================
+
+To find out which data services are supported by the hardware
+applications can call the
+:ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl.
+All drivers implementing the sliced VBI interface must support this
+ioctl. The results may differ from those of the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl when the number of VBI
+lines the hardware can capture or output per frame, or the number of
+services it can identify on a given line are limited. For example on PAL
+line 16 the hardware may be able to look for a VPS or Teletext signal,
+but not both at the same time.
+
+To determine the currently selected services applications set the
+``type`` field of struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` or
+``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``, and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl fills the ``fmt.sliced``
+member, a struct
+:c:type:`v4l2_sliced_vbi_format`.
+
+Applications can request different parameters by initializing or
+modifying the ``fmt.sliced`` member and calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with a pointer to the
+struct :c:type:`v4l2_format` structure.
+
+The sliced VBI API is more complicated than the raw VBI API because the
+hardware must be told which VBI service to expect on each scan line. Not
+all services may be supported by the hardware on all lines (this is
+especially true for VBI output where Teletext is often unsupported and
+other services can only be inserted in one specific line). In many
+cases, however, it is sufficient to just set the ``service_set`` field
+to the required services and let the driver fill the ``service_lines``
+array according to hardware capabilities. Only if more precise control
+is needed should the programmer set the ``service_lines`` array
+explicitly.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl modifies the parameters
+according to hardware capabilities. When the driver allocates resources
+at this point, it may return an ``EBUSY`` error code if the required
+resources are temporarily unavailable. Other resource allocation points
+which may return ``EBUSY`` can be the
+:ref:`VIDIOC_STREAMON` ioctl and the first
+:ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call.

+
+To assure synchronization and to distinguish from frame dropping, when a

+must pass one or more empty packets. When an application fails to pass

+packet again, and disable the output of Closed Caption and Teletext
+data, or output data which is ignored by Closed Caption and Teletext
+decoders.
+
+A sliced VBI device may support :ref:`read/write <rw>` and/or

+:ref:`user pointer <userp>`) I/O. The latter bears the possibility of

+
+
+Sliced VBI Data in MPEG Streams
+===============================
+
+If a device can produce an MPEG output stream, it may be capable of
+providing
+:ref:`negotiated sliced VBI services <sliced-vbi-format-negotitation>`
+as data embedded in the MPEG stream. Users or applications control this
+sliced VBI data insertion with the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control.
+
+If the driver does not provide the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control, or only allows that control to be set to
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`,
+then the device cannot embed sliced VBI data in the MPEG stream.
+
+The
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control does not implicitly set the device driver to capture nor cease
+capturing sliced VBI data. The control only indicates to embed sliced
+VBI data in the MPEG stream, if an application has negotiated sliced VBI
+service be captured.
+
+It may also be the case that a device can embed sliced VBI data in only
+certain types of MPEG streams: for example in an MPEG-2 PS but not an
+MPEG-2 TS. In this situation, if sliced VBI data insertion is requested,
+the sliced VBI data will be embedded in MPEG stream types when
+supported, and silently omitted from MPEG stream types where sliced VBI
+data insertion is not supported by the device.
+
+The following subsections specify the format of the embedded sliced VBI
+data.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: NONE
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format shall be interpreted by drivers as a control
+to cease embedding sliced VBI data in MPEG streams. Neither the device
+nor driver shall insert "empty" embedded sliced VBI data packets in the
+MPEG stream when this format is set. No MPEG stream data structures are
+specified for this format.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: IVTV
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format, when supported, indicates to the driver to
+embed up to 36 lines of sliced VBI data per frame in an MPEG-2 *Private
+Stream 1 PES* packet encapsulated in an MPEG-2 *Program Pack* in the
+MPEG stream.
+
+*Historical context*: This format specification originates from a
+custom, embedded, sliced VBI data format used by the ``ivtv`` driver.
+This format has already been informally specified in the kernel sources
+in the file ``Documentation/userspace-api/media/drivers/cx2341x-uapi.rst`` . The
+maximum size of the payload and other aspects of this format are driven
+by the CX23415 MPEG decoder's capabilities and limitations with respect
+to extracting, decoding, and displaying sliced VBI data embedded within
+an MPEG stream.
+
+This format's use is *not* exclusive to the ``ivtv`` driver *nor*
+exclusive to CX2341x devices, as the sliced VBI data packet insertion
+into the MPEG stream is implemented in driver software. At least the
+``cx18`` driver provides sliced VBI data insertion into an MPEG-2 PS in
+this format as well.
+
+The following definitions specify the payload of the MPEG-2 *Private
+Stream 1 PES* packets that contain sliced VBI data when
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`

+********************
+Sub-device Interface
+********************
+
+The complex nature of V4L2 devices, where hardware is often made of
+several integrated circuits that need to interact with each other in a
+controlled way, leads to complex V4L2 drivers. The drivers usually
+reflect the hardware model in software, and model the different hardware
+components as software blocks called sub-devices.
+
+V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
+implements the media device API, they will automatically inherit from
+media entities. Applications will be able to enumerate the sub-devices
+and discover the hardware topology using the media entities, pads and
+links enumeration API.
+
+In addition to make sub-devices discoverable, drivers can also choose to
+make them directly configurable by applications. When both the
+sub-device driver and the V4L2 device driver support this, sub-devices
+will feature a character device node on which ioctls can be called to
+
+-  query, read and write sub-devices controls
+
+-  subscribe and unsubscribe to events and retrieve them
+
+-  negotiate image formats on individual pads
+
+Sub-device character device nodes, conventionally named
+``/dev/v4l-subdev*``, use major number 81.
+
+Drivers may opt to limit the sub-device character devices to only expose
+operations that do not modify the device state. In such a case the sub-devices
+are referred to as ``read-only`` in the rest of this documentation, and the
+related restrictions are documented in individual ioctls.
+
+
+Controls
+========
+
+Most V4L2 controls are implemented by sub-device hardware. Drivers
+usually merge all controls and expose them through video device nodes.
+Applications can control all sub-devices through a single interface.
+
+Complex devices sometimes implement the same control in different pieces
+of hardware. This situation is common in embedded platforms, where both
+sensors and image processing hardware implement identical functions,
+such as contrast adjustment, white balance or faulty pixels correction.
+As the V4L2 controls API doesn't support several identical controls in a
+single device, all but one of the identical controls are hidden.
+
+Applications can access those hidden controls through the sub-device
+node with the V4L2 control API described in :ref:`control`. The ioctls
+behave identically as when issued on V4L2 device nodes, with the
+exception that they deal only with controls implemented in the
+sub-device.
+
+Depending on the driver, those controls might also be exposed through
+one (or several) V4L2 device nodes.
+
+
+Events
+======
+
+V4L2 sub-devices can notify applications of events as described in
+:ref:`event`. The API behaves identically as when used on V4L2 device
+nodes, with the exception that it only deals with events generated by
+the sub-device. Depending on the driver, those events might also be
+reported on one (or several) V4L2 device nodes.
+
+
+.. _pad-level-formats:
+
+Pad-level Formats
+=================
+
+.. warning::
+
+    Pad-level formats are only applicable to very complex devices that
+    need to expose low-level format configuration to user space. Generic
+    V4L2 applications do *not* need to use the API described in this
+    section.
+
+.. note::
+
+    For the purpose of this section, the term *format* means the
+    combination of media bus data format, frame width and frame height.
+
+Image formats are typically negotiated on video capture and output
+devices using the format and
+:ref:`selection <VIDIOC_SUBDEV_G_SELECTION>` ioctls. The driver is
+responsible for configuring every block in the video pipeline according
+to the requested format at the pipeline input and/or output.
+
+For complex devices, such as often found in embedded systems, identical
+image sizes at the output of a pipeline can be achieved using different
+hardware configurations. One such example is shown on
+:ref:`pipeline-scaling`, where image scaling can be performed on both
+the video sensor and the host image processing hardware.
+
+
+.. _pipeline-scaling:
+
+.. kernel-figure:: pipeline.dot
+    :alt:   pipeline.dot
+    :align: center
+
+    Image Format Negotiation on Pipelines
+
+    High quality and high speed pipeline configuration
+
+
+
+The sensor scaler is usually of less quality than the host scaler, but
+scaling on the sensor is required to achieve higher frame rates.
+Depending on the use case (quality vs. speed), the pipeline must be
+configured differently. Applications need to configure the formats at
+every point in the pipeline explicitly.
+
+Drivers that implement the :ref:`media API <media-controller-intro>`
+can expose pad-level image format configuration to applications. When
+they do, applications can use the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls. to
+negotiate formats on a per-pad basis.
+
+Applications are responsible for configuring coherent parameters on the
+whole pipeline and making sure that connected pads have compatible
+formats. The pipeline is checked for formats mismatch at
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` time, and an ``EPIPE`` error
+code is then returned if the configuration is invalid.
+
+Pad-level image format configuration support can be tested by calling
+the :ref:`VIDIOC_SUBDEV_G_FMT` ioctl on pad
+0. If the driver returns an ``EINVAL`` error code pad-level format
+configuration is not supported by the sub-device.
+
+
+Format Negotiation
+------------------
+
+Acceptable formats on pads can (and usually do) depend on a number of
+external parameters, such as formats on other pads, active links, or
+even controls. Finding a combination of formats on all pads in a video
+pipeline, acceptable to both application and driver, can't rely on
+formats enumeration only. A format negotiation mechanism is required.
+
+Central to the format negotiation mechanism are the get/set format
+operations. When called with the ``which`` argument set to
+:ref:`V4L2_SUBDEV_FORMAT_TRY <VIDIOC_SUBDEV_G_FMT>`, the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls operate on
+a set of formats parameters that are not connected to the hardware
+configuration. Modifying those 'try' formats leaves the device state
+untouched (this applies to both the software state stored in the driver
+and the hardware state stored in the device itself).
+
+While not kept as part of the device state, try formats are stored in
+the sub-device file handles. A
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` call will return
+the last try format set *on the same sub-device file handle*. Several
+applications querying the same sub-device at the same time will thus not
+interact with each other.
+
+To find out whether a particular format is supported by the device,
+applications use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl. Drivers
+verify and, if needed, change the requested ``format`` based on device
+requirements and return the possibly modified value. Applications can
+then choose to try a different format or accept the returned value and
+continue.
+
+Formats returned by the driver during a negotiation iteration are
+guaranteed to be supported by the device. In particular, drivers
+guarantee that a returned format will not be further changed if passed
+to an :ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` call as-is
+(as long as external parameters, such as formats on other pads or links'
+configuration are not changed).
+
+Drivers automatically propagate formats inside sub-devices. When a try
+or active format is set on a pad, corresponding formats on other pads of
+the same sub-device can be modified by the driver. Drivers are free to
+modify formats as required by the device. However, they should comply
+with the following rules when possible:
+
+-  Formats should be propagated from sink pads to source pads. Modifying
+   a format on a source pad should not modify the format on any sink
+   pad.
+
+-  Sub-devices that scale frames using variable scaling factors should
+   reset the scale factors to default values when sink pads formats are
+   modified. If the 1:1 scaling ratio is supported, this means that
+   source pads formats should be reset to the sink pads formats.
+
+Formats are not propagated across links, as that would involve
+propagating them from one sub-device file handle to another.
+Applications must then take care to configure both ends of every link
+explicitly with compatible formats. Identical formats on the two ends of
+a link are guaranteed to be compatible. Drivers are free to accept
+different formats matching device requirements as being compatible.

+1. Initial state. The sensor source pad format is set to its native 3MP
+   size and V4L2_MBUS_FMT_SGRBG8_1X8 media bus code. Formats on the
+   host frontend and scaler sink and source pads have the default
+   values, as well as the compose rectangle on the scaler's sink pad.
+
+2. The application configures the frontend sink pad format's size to
+   2048x1536 and its media bus code to V4L2_MBUS_FMT_SGRBG_1X8. The
+   driver propagates the format to the frontend source pad.
+
+3. The application configures the scaler sink pad format's size to
+   2046x1534 and the media bus code to V4L2_MBUS_FMT_SGRBG_1X8 to
+   match the frontend source size and media bus code. The media bus code
+   on the sink pad is set to V4L2_MBUS_FMT_SGRBG_1X8. The driver
+   propagates the size to the compose selection rectangle on the
+   scaler's sink pad, and the format to the scaler source pad.
+
+4. The application configures the size of the compose selection
+   rectangle of the scaler's sink pad 1280x960. The driver propagates
+   the size to the scaler's source pad format.
+
+When satisfied with the try results, applications can set the active
+formats by setting the ``which`` argument to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. Active formats are changed exactly as try
+formats by drivers. To avoid modifying the hardware state during format
+negotiation, applications should negotiate try formats first and then
+modify the active settings using the try formats returned during the
+last negotiation iteration. This guarantees that the active format will
+be applied as-is by the driver without being modified.
+
+
+.. _v4l2-subdev-selections:
+
+Selections: cropping, scaling and composition
+---------------------------------------------
+
+Many sub-devices support cropping frames on their input or output pads
+(or possible even on both). Cropping is used to select the area of
+interest in an image, typically on an image sensor or a video decoder.
+It can also be used as part of digital zoom implementations to select
+the area of the image that will be scaled up.
+
+Crop settings are defined by a crop rectangle and represented in a
+struct :c:type:`v4l2_rect` by the coordinates of the top
+left corner and the rectangle size. Both the coordinates and sizes are
+expressed in pixels.
+
+As for pad formats, drivers store try and active rectangles for the
+selection targets :ref:`v4l2-selections-common`.
+
+On sink pads, cropping is applied relative to the current pad format.
+The pad format represents the image size as received by the sub-device
+from the previous block in the pipeline, and the crop rectangle
+represents the sub-image that will be transmitted further inside the
+sub-device for processing.
+
+The scaling operation changes the size of the image by scaling it to new
+dimensions. The scaling ratio isn't specified explicitly, but is implied
+from the original and scaled image sizes. Both sizes are represented by
+struct :c:type:`v4l2_rect`.
+
+Scaling support is optional. When supported by a subdev, the crop
+rectangle on the subdev's sink pad is scaled to the size configured
+using the
+:ref:`VIDIOC_SUBDEV_S_SELECTION <VIDIOC_SUBDEV_G_SELECTION>` IOCTL
+using ``V4L2_SEL_TGT_COMPOSE`` selection target on the same pad. If the
+subdev supports scaling but not composing, the top and left values are
+not used and must always be set to zero.
+
+On source pads, cropping is similar to sink pads, with the exception
+that the source size from which the cropping is performed, is the
+COMPOSE rectangle on the sink pad. In both sink and source pads, the
+crop rectangle must be entirely contained inside the source image size
+for the crop operation.
+
+The drivers should always use the closest possible rectangle the user
+requests on all selection targets, unless specifically told otherwise.
+``V4L2_SEL_FLAG_GE`` and ``V4L2_SEL_FLAG_LE`` flags may be used to round
+the image size either up or down. :ref:`v4l2-selection-flags`
+
+
+Types of selection targets
+--------------------------
+
+
+Actual targets
+^^^^^^^^^^^^^^
+
+Actual targets (without a postfix) reflect the actual hardware
+configuration at any point of time. There is a BOUNDS target
+corresponding to every actual target.
+
+
+BOUNDS targets
+^^^^^^^^^^^^^^
+
+BOUNDS targets is the smallest rectangle that contains all valid actual
+rectangles. It may not be possible to set the actual rectangle as large
+as the BOUNDS rectangle, however. This may be because e.g. a sensor's
+pixel array is not rectangular but cross-shaped or round. The maximum
+size may also be smaller than the BOUNDS rectangle.
+
+
+Order of configuration and format propagation
+---------------------------------------------
+
+Inside subdevs, the order of image processing steps will always be from
+the sink pad towards the source pad. This is also reflected in the order
+in which the configuration must be performed by the user: the changes
+made will be propagated to any subsequent stages. If this behaviour is
+not desired, the user must set ``V4L2_SEL_FLAG_KEEP_CONFIG`` flag. This
+flag causes no propagation of the changes are allowed in any
+circumstances. This may also cause the accessed rectangle to be adjusted
+by the driver, depending on the properties of the underlying hardware.
+
+The coordinates to a step always refer to the actual size of the
+previous step. The exception to this rule is the sink compose
+rectangle, which refers to the sink compose bounds rectangle --- if it
+is supported by the hardware.
+
+1. Sink pad format. The user configures the sink pad format. This format
+   defines the parameters of the image the entity receives through the
+   pad for further processing.
+
+2. Sink pad actual crop selection. The sink pad crop defines the crop
+   performed to the sink pad format.
+
+3. Sink pad actual compose selection. The size of the sink pad compose
+   rectangle defines the scaling ratio compared to the size of the sink
+   pad crop rectangle. The location of the compose rectangle specifies
+   the location of the actual sink compose rectangle in the sink compose
+   bounds rectangle.
+
+4. Source pad actual crop selection. Crop on the source pad defines crop
+   performed to the image in the sink compose bounds rectangle.
+
+5. Source pad format. The source pad format defines the output pixel
+   format of the subdev, as well as the other parameters with the
+   exception of the image width and height. Width and height are defined
+   by the size of the source pad actual crop selection.
+
+Accessing any of the above rectangles not supported by the subdev will
+return ``EINVAL``. Any rectangle referring to a previous unsupported
+rectangle coordinates will instead refer to the previous supported
+rectangle. For example, if sink crop is not supported, the compose
+selection will refer to the sink pad format dimensions instead.

+    :align: center
+
+    **Figure 4.5. Image processing in subdevs: simple crop example**
+
+In the above example, the subdev supports cropping on its sink pad. To
+configure it, the user sets the media bus format on the subdev's sink
+pad. Now the actual crop rectangle can be set on the sink pad --- the
+location and size of this rectangle reflect the location and size of a
+rectangle to be cropped from the sink format. The size of the sink crop
+rectangle will also be the size of the format of the subdev's source
+pad.

+
+    **Figure 4.6. Image processing in subdevs: scaling with multiple sources**
+
+In this example, the subdev is capable of first cropping, then scaling
+and finally cropping for two source pads individually from the resulting
+scaled image. The location of the scaled image in the cropped image is
+ignored in sink compose target. Both of the locations of the source crop
+rectangles refer to the sink scaling rectangle, independently cropping
+an area at location specified by the source crop rectangle from it.

+    :align:  center
+
+    **Figure 4.7. Image processing in subdevs: scaling and composition with multiple sinks and sources**
+
+The subdev driver supports two sink pads and two source pads. The images
+from both of the sink pads are individually cropped, then scaled and
+further composed on the composition bounds rectangle. From that, two
+independent streams are cropped and sent out of the subdev from the
+source pads.

+Touch Devices
+*************
+
+Touch devices are accessed through character device special files named
+``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+Overview
+========
+
+Sensors may be Optical, or Projected Capacitive touch (PCT).
+
+Processing is required to analyse the raw data and produce input events. In
+some systems, this may be performed on the ASIC and the raw data is purely a
+side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
+analogue front end device which delivers touch data at high rate, and any touch
+processing must be done on the host.
+
+For capacitive touch sensing, the touchscreen is composed of an array of
+horizontal and vertical conductors (alternatively called rows/columns, X/Y
+lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
+conductors cross. Alternatively, Self Capacitance measures the signal from each
+column and row independently.
+
+A touch input may be determined by comparing the raw capacitance measurement to
+a no-touch reference (or "baseline") measurement:
+
+Delta = Raw - Reference
+
+The reference measurement takes account of variations in the capacitance across
+the touch sensor matrix, for example manufacturing irregularities,
+environmental or edge effects.
+
+Querying Capabilities
+=====================
+
+Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
+and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+At least one of the read/write or streaming I/O methods must be
+supported.
+
+The formats supported by touch devices are documented in
+:ref:`Touch Formats <tch-formats>`.
+
+Data Format Negotiation
+=======================
+
+A touch device may support any I/O method.

+********************************
+Differences between V4L and V4L2
+********************************
+
+The Video For Linux API was first introduced in Linux 2.1 to unify and
+replace various TV and radio device related interfaces, developed
+independently by driver writers in prior years. Starting with Linux 2.5
+the much improved V4L2 API replaces the V4L API. The support for the old
+V4L calls were removed from Kernel, but the library :ref:`libv4l`
+supports the conversion of a V4L API system call into a V4L2 one.
+
+
+Opening and Closing Devices
+===========================
+
+For compatibility reasons the character device file names recommended
+for V4L2 video capture, overlay, radio and raw vbi capture devices did
+not change from those used by V4L. They are listed in :ref:`devices`
+and below in :ref:`v4l-dev`.
+
+The teletext devices (minor range 192-223) have been removed in V4L2 and
+no longer exist. There is no hardware available anymore for handling
+pure teletext. Instead raw or sliced VBI is used.
+
+The V4L ``videodev`` module automatically assigns minor numbers to
+drivers in load order, depending on the registered device type. We
+recommend that V4L2 drivers by default register devices with the same
+numbers, but the system administrator can assign arbitrary minor numbers
+using driver module options. The major device number remains 81.

+
+
+V4L prohibits (or used to prohibit) multiple opens of a device file.
+V4L2 drivers *may* support multiple opens, see :ref:`open` for details
+and consequences.
+
+V4L drivers respond to V4L2 ioctls with an ``EINVAL`` error code.
+
+
+Querying Capabilities
+=====================
+
+The V4L ``VIDIOCGCAP`` ioctl is equivalent to V4L2's
+:ref:`VIDIOC_QUERYCAP`.
+
+The ``name`` field in struct ``video_capability`` became
+``card`` in struct :c:type:`v4l2_capability`, ``type``
+was replaced by ``capabilities``. Note V4L2 does not distinguish between
+device types like this, better think of basic video input, video output
+and radio devices supporting a set of related functions like video
+capturing, video overlay and VBI capturing. See :ref:`open` for an
+introduction.

+
+
+The ``audios`` field was replaced by ``capabilities`` flag
+``V4L2_CAP_AUDIO``, indicating *if* the device has any audio inputs or
+outputs. To determine their number applications can enumerate audio
+inputs with the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl. The
+audio ioctls are described in :ref:`audio`.
+
+The ``maxwidth``, ``maxheight``, ``minwidth`` and ``minheight`` fields
+were removed. Calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl with the desired
+dimensions returns the closest size possible, taking into account the
+current video standard, cropping and scaling limitations.
+
+
+Video Sources
+=============
+
+V4L provides the ``VIDIOCGCHAN`` and ``VIDIOCSCHAN`` ioctl using struct
+``video_channel`` to enumerate the video inputs of a V4L
+device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_ENUMINPUT`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` using struct
+:c:type:`v4l2_input` as discussed in :ref:`video`.
+
+The ``channel`` field counting inputs was renamed to ``index``, the
+video input types were renamed as follows:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_channel`` ``type``
+      - struct :c:type:`v4l2_input` ``type``
+    * - ``VIDEO_TYPE_TV``
+      - ``V4L2_INPUT_TYPE_TUNER``
+    * - ``VIDEO_TYPE_CAMERA``
+      - ``V4L2_INPUT_TYPE_CAMERA``
+
+
+Unlike the ``tuners`` field expressing the number of tuners of this
+input, V4L2 assumes each video input is connected to at most one tuner.
+However a tuner can have more than one input, i. e. RF connectors, and a
+device can have multiple tuners. The index number of the tuner
+associated with the input, if any, is stored in field ``tuner`` of
+struct :c:type:`v4l2_input`. Enumeration of tuners is
+discussed in :ref:`tuner`.
+
+The redundant ``VIDEO_VC_TUNER`` flag was dropped. Video inputs
+associated with a tuner are of type ``V4L2_INPUT_TYPE_TUNER``. The
+``VIDEO_VC_AUDIO`` flag was replaced by the ``audioset`` field. V4L2
+considers devices with up to 32 audio inputs. Each set bit in the
+``audioset`` field represents one audio input this video input combines
+with. For information about audio inputs and how to switch between them
+see :ref:`audio`.
+
+The ``norm`` field describing the supported video standards was replaced
+by ``std``. The V4L specification mentions a flag ``VIDEO_VC_NORM``
+indicating whether the standard can be changed. This flag was a later
+addition together with the ``norm`` field and has been removed in the
+meantime. V4L2 has a similar, albeit more comprehensive approach to
+video standards, see :ref:`standard` for more information.
+
+
+Tuning
+======
+
+The V4L ``VIDIOCGTUNER`` and ``VIDIOCSTUNER`` ioctl and struct
+``video_tuner`` can be used to enumerate the tuners of a
+V4L TV or radio device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` using struct
+:c:type:`v4l2_tuner`. Tuners are covered in :ref:`tuner`.
+
+The ``tuner`` field counting tuners was renamed to ``index``. The fields
+``name``, ``rangelow`` and ``rangehigh`` remained unchanged.
+
+The ``VIDEO_TUNER_PAL``, ``VIDEO_TUNER_NTSC`` and ``VIDEO_TUNER_SECAM``
+flags indicating the supported video standards were dropped. This
+information is now contained in the associated struct
+:c:type:`v4l2_input`. No replacement exists for the
+``VIDEO_TUNER_NORM`` flag indicating whether the video standard can be
+switched. The ``mode`` field to select a different video standard was
+replaced by a whole new set of ioctls and structures described in
+:ref:`standard`. Due to its ubiquity it should be mentioned the BTTV
+driver supports several standards in addition to the regular
+``VIDEO_MODE_PAL`` (0), ``VIDEO_MODE_NTSC``, ``VIDEO_MODE_SECAM`` and
+``VIDEO_MODE_AUTO`` (3). Namely N/PAL Argentina, M/PAL, N/PAL, and NTSC
+Japan with numbers 3-6 (sic).
+
+The ``VIDEO_TUNER_STEREO_ON`` flag indicating stereo reception became
+``V4L2_TUNER_SUB_STEREO`` in field ``rxsubchans``. This field also
+permits the detection of monaural and bilingual audio, see the
+definition of struct :c:type:`v4l2_tuner` for details.
+Presently no replacement exists for the ``VIDEO_TUNER_RDS_ON`` and
+``VIDEO_TUNER_MBS_ON`` flags.
+
+The ``VIDEO_TUNER_LOW`` flag was renamed to ``V4L2_TUNER_CAP_LOW`` in
+the struct :c:type:`v4l2_tuner` ``capability`` field.
+
+The ``VIDIOCGFREQ`` and ``VIDIOCSFREQ`` ioctl to change the tuner
+frequency where renamed to
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`. They take a pointer
+to a struct :c:type:`v4l2_frequency` instead of an
+unsigned long integer.
+
+
+.. _v4l-image-properties:
+
+Image Properties
+================
+
+V4L2 has no equivalent of the ``VIDIOCGPICT`` and ``VIDIOCSPICT`` ioctl
+and struct ``video_picture``. The following fields where
+replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+

+      - ``V4L2_CID_CONTRAST``
+    * - ``whiteness``
+      - ``V4L2_CID_WHITENESS``
+
+
+The V4L picture controls are assumed to range from 0 to 65535 with no
+particular reset value. The V4L2 API permits arbitrary limits and
+defaults which can be queried with the
+:ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+The ``depth`` (average number of bits per pixel) of a video image is
+implied by the selected image format. V4L2 does not explicitly provide
+such information assuming applications recognizing the format are aware
+of the image depth and others need not know. The ``palette`` field moved
+into the struct :c:type:`v4l2_pix_format`:

+
+
+V4L2 image formats are defined in :ref:`pixfmt`. The image format can
+be selected with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Audio
+=====
+
+The ``VIDIOCGAUDIO`` and ``VIDIOCSAUDIO`` ioctl and struct
+``video_audio`` are used to enumerate the audio inputs
+of a V4L device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` using struct
+:c:type:`v4l2_audio` as discussed in :ref:`audio`.
+
+The ``audio`` "channel number" field counting audio inputs was renamed
+to ``index``.
+
+On ``VIDIOCSAUDIO`` the ``mode`` field selects *one* of the
+``VIDEO_SOUND_MONO``, ``VIDEO_SOUND_STEREO``, ``VIDEO_SOUND_LANG1`` or
+``VIDEO_SOUND_LANG2`` audio demodulation modes. When the current audio
+standard is BTSC ``VIDEO_SOUND_LANG2`` refers to SAP and
+``VIDEO_SOUND_LANG1`` is meaningless. Also undocumented in the V4L
+specification, there is no way to query the selected mode. On
+``VIDIOCGAUDIO`` the driver returns the *actually received* audio
+programmes in this field. In the V4L2 API this information is stored in
+the struct :c:type:`v4l2_tuner` ``rxsubchans`` and
+``audmode`` fields, respectively. See :ref:`tuner` for more
+information on tuners. Related to audio modes struct
+:c:type:`v4l2_audio` also reports if this is a mono or
+stereo input, regardless if the source is a tuner.
+
+The following fields where replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_audio``
+      - V4L2 Control ID
+    * - ``volume``
+      - ``V4L2_CID_AUDIO_VOLUME``
+    * - ``bass``
+      - ``V4L2_CID_AUDIO_BASS``
+    * - ``treble``
+      - ``V4L2_CID_AUDIO_TREBLE``
+    * - ``balance``
+      - ``V4L2_CID_AUDIO_BALANCE``
+
+
+To determine which of these controls are supported by a driver V4L
+provides the ``flags`` ``VIDEO_AUDIO_VOLUME``, ``VIDEO_AUDIO_BASS``,
+``VIDEO_AUDIO_TREBLE`` and ``VIDEO_AUDIO_BALANCE``. In the V4L2 API the
+:ref:`VIDIOC_QUERYCTRL` ioctl reports if the
+respective control is supported. Accordingly the ``VIDEO_AUDIO_MUTABLE``
+and ``VIDEO_AUDIO_MUTE`` flags where replaced by the boolean
+``V4L2_CID_AUDIO_MUTE`` control.
+
+All V4L2 controls have a ``step`` attribute replacing the struct
+``video_audio`` ``step`` field. The V4L audio controls
+are assumed to range from 0 to 65535 with no particular reset value. The
+V4L2 API permits arbitrary limits and defaults which can be queried with
+the :ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+
+Frame Buffer Overlay
+====================
+
+The V4L2 ioctls equivalent to ``VIDIOCGFBUF`` and ``VIDIOCSFBUF`` are
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The ``base`` field of struct
+``video_buffer`` remained unchanged, except V4L2 defines
+a flag to indicate non-destructive overlays instead of a ``NULL``
+pointer. All other fields moved into the struct
+:c:type:`v4l2_pix_format` ``fmt`` substructure of
+struct :c:type:`v4l2_framebuffer`. The ``depth``
+field was replaced by ``pixelformat``. See :ref:`pixfmt-rgb` for a
+list of RGB formats and their respective color depths.
+
+Instead of the special ioctls ``VIDIOCGWIN`` and ``VIDIOCSWIN`` V4L2
+uses the general-purpose data format negotiation ioctls
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:c:type:`v4l2_format` as argument. Here the ``win`` member
+of the ``fmt`` union is used, a struct
+:c:type:`v4l2_window`.
+
+The ``x``, ``y``, ``width`` and ``height`` fields of struct
+``video_window`` moved into struct
+:c:type:`v4l2_rect` substructure ``w`` of struct
+:c:type:`v4l2_window`. The ``chromakey``, ``clips``, and
+``clipcount`` fields remained unchanged. Struct
+``video_clip`` was renamed to struct
+:c:type:`v4l2_clip`, also containing a struct
+:c:type:`v4l2_rect`, but the semantics are still the same.
+
+The ``VIDEO_WINDOW_INTERLACE`` flag was dropped. Instead applications
+must set the ``field`` field to ``V4L2_FIELD_ANY`` or
+``V4L2_FIELD_INTERLACED``. The ``VIDEO_WINDOW_CHROMAKEY`` flag moved
+into struct :c:type:`v4l2_framebuffer`, under the new
+name ``V4L2_FBUF_FLAG_CHROMAKEY``.
+
+In V4L, storing a bitmap pointer in ``clips`` and setting ``clipcount``
+to ``VIDEO_CLIP_BITMAP`` (-1) requests bitmap clipping, using a fixed
+size bitmap of 1024 × 625 bits. Struct :c:type:`v4l2_window`
+has a separate ``bitmap`` pointer field for this purpose and the bitmap
+size is determined by ``w.width`` and ``w.height``.
+
+The ``VIDIOCCAPTURE`` ioctl to enable or disable overlay was renamed to
+:ref:`VIDIOC_OVERLAY`.
+
+
+Cropping
+========
+
+To capture only a subsection of the full picture V4L defines the
+``VIDIOCGCAPTURE`` and ``VIDIOCSCAPTURE`` ioctls using struct
+``video_capture``. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` using struct
+:c:type:`v4l2_crop`, and the related
+:ref:`VIDIOC_CROPCAP` ioctl. This is a rather
+complex matter, see :ref:`crop` for details.
+
+The ``x``, ``y``, ``width`` and ``height`` fields moved into struct
+:c:type:`v4l2_rect` substructure ``c`` of struct
+:c:type:`v4l2_crop`. The ``decimation`` field was dropped. In
+the V4L2 API the scaling factor is implied by the size of the cropping
+rectangle and the size of the captured or overlaid image.
+
+The ``VIDEO_CAPTURE_ODD`` and ``VIDEO_CAPTURE_EVEN`` flags to capture
+only the odd or even field, respectively, were replaced by
+``V4L2_FIELD_TOP`` and ``V4L2_FIELD_BOTTOM`` in the field named
+``field`` of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_window`. These structures are used to
+select a capture or overlay format with the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Reading Images, Memory Mapping
+==============================
+
+
+Capturing using the read method
+-------------------------------
+
+There is no essential difference between reading images from a V4L or
+V4L2 device using the :ref:`read() <func-read>` function, however V4L2
+drivers are not required to support this I/O method. Applications can
+determine if the function is available with the
+:ref:`VIDIOC_QUERYCAP` ioctl. All V4L2 devices
+exchanging data with applications must support the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.
+
+To select an image format and size, V4L provides the ``VIDIOCSPICT`` and
+``VIDIOCSWIN`` ioctls. V4L2 uses the general-purpose data format
+negotiation ioctls :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:c:type:`v4l2_format` as argument, here the struct
+:c:type:`v4l2_pix_format` named ``pix`` of its
+``fmt`` union is used.
+
+For more information about the V4L2 read interface see :ref:`rw`.
+
+
+Capturing using memory mapping
+------------------------------
+
+Applications can read from V4L devices by mapping buffers in device
+memory, or more often just buffers allocated in DMA-able system memory,
+into their address space. This avoids the data copying overhead of the
+read method. V4L2 supports memory mapping as well, with a few
+differences.
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - V4L
+      - V4L2
+    * -
+      - The image format must be selected before buffers are allocated,
+	with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When no
+	format is selected the driver may use the last, possibly by
+	another application requested format.
+    * - Applications cannot change the number of buffers. The it is built
+	into the driver, unless it has a module option to change the
+	number when the driver module is loaded.
+      - The :ref:`VIDIOC_REQBUFS` ioctl allocates the
+	desired number of buffers, this is a required step in the
+	initialization sequence.
+    * - Drivers map all buffers as one contiguous range of memory. The
+	``VIDIOCGMBUF`` ioctl is available to query the number of buffers,
+	the offset of each buffer from the start of the virtual file, and
+	the overall amount of memory used, which can be used as arguments
+	for the :ref:`mmap() <func-mmap>` function.
+      - Buffers are individually mapped. The offset and size of each
+	buffer can be determined with the
+	:ref:`VIDIOC_QUERYBUF` ioctl.
+    * - The ``VIDIOCMCAPTURE`` ioctl prepares a buffer for capturing. It
+	also determines the image format for this buffer. The ioctl
+	returns immediately, eventually with an ``EAGAIN`` error code if no
+	video signal had been detected. When the driver supports more than
+	one buffer applications can call the ioctl multiple times and thus
+	have multiple outstanding capture requests.
+
+	The ``VIDIOCSYNC`` ioctl suspends execution until a particular
+	buffer has been filled.
+      - Drivers maintain an incoming and outgoing queue.
+	:ref:`VIDIOC_QBUF` enqueues any empty buffer into
+	the incoming queue. Filled buffers are dequeued from the outgoing
+	queue with the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. To wait
+	until filled buffers become available this function,
+	:ref:`select() <func-select>` or :ref:`poll() <func-poll>` can
+	be used. The :ref:`VIDIOC_STREAMON` ioctl
+	must be called once after enqueuing one or more buffers to start
+	capturing. Its counterpart
+	:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` stops capturing and
+	dequeues all buffers from both queues. Applications can query the
+	signal status, if known, with the
+	:ref:`VIDIOC_ENUMINPUT` ioctl.
+
+
+For a more in-depth discussion of memory mapping and examples, see
+:ref:`mmap`.
+
+
+Reading Raw VBI Data
+====================
+
+Originally the V4L API did not specify a raw VBI capture interface, only
+the device file ``/dev/vbi`` was reserved for this purpose. The only
+driver supporting this interface was the BTTV driver, de-facto defining
+the V4L VBI interface. Reading from the device yields a raw VBI image
+with the following parameters:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct :c:type:`v4l2_vbi_format`
+      - V4L, BTTV driver
+    * - sampling_rate
+      - 28636363 Hz NTSC (or any other 525-line standard); 35468950 Hz PAL
+	and SECAM (625-line standards)
+    * - offset
+      - ?
+    * - samples_per_line
+      - 2048
+    * - sample_format
+      - V4L2_PIX_FMT_GREY. The last four bytes (a machine endianness
+	integer) contain a frame counter.
+    * - start[]
+      - 10, 273 NTSC; 22, 335 PAL and SECAM
+    * - count[]
+      - 16, 16 [#f9]_
+    * - flags
+      - 0
+
+
+Undocumented in the V4L specification, in Linux 2.3 the
+``VIDIOCGVBIFMT`` and ``VIDIOCSVBIFMT`` ioctls using struct
+``vbi_format`` were added to determine the VBI image
+parameters. These ioctls are only partially compatible with the V4L2 VBI
+interface specified in :ref:`raw-vbi`.
+
+An ``offset`` field does not exist, ``sample_format`` is supposed to be
+``VIDEO_PALETTE_RAW``, equivalent to ``V4L2_PIX_FMT_GREY``. The
+remaining fields are probably equivalent to struct
+:c:type:`v4l2_vbi_format`.
+
+Apparently only the Zoran (ZR 36120) driver implements these ioctls. The
+semantics differ from those specified for V4L2 in two ways. The
+parameters are reset on :ref:`open() <func-open>` and
+``VIDIOCSVBIFMT`` always returns an ``EINVAL`` error code if the parameters
+are invalid.
+
+
+Miscellaneous
+=============
+
+V4L2 has no equivalent of the ``VIDIOCGUNIT`` ioctl. Applications can
+find the VBI device associated with a video capture device (or vice
+versa) by reopening the device and requesting VBI data. For details see
+:ref:`open`.
+
+No replacement exists for ``VIDIOCKEY``, and the V4L functions for
+microcode programming. A new interface for MPEG compression and playback
+devices is documented in :ref:`extended-controls`.
+
+.. [#f1]
+   According to Documentation/admin-guide/devices.rst these should be symbolic links
+   to ``/dev/video0``. Note the original bttv interface is not
+   compatible with V4L or V4L2.
+
+.. [#f2]
+   According to ``Documentation/admin-guide/devices.rst`` a symbolic link to
+   ``/dev/radio0``.
+
+.. [#f3]
+   This is a custom format used by the BTTV driver, not one of the V4L2
+   standard formats.
+
+.. [#f4]
+   Presumably all V4L RGB formats are little-endian, although some
+   drivers might interpret them according to machine endianness. V4L2
+   defines little-endian, big-endian and red/blue swapped variants. For
+   details see :ref:`pixfmt-rgb`.
+
+.. [#f5]
+   ``VIDEO_PALETTE_YUV422`` and ``VIDEO_PALETTE_YUYV`` are the same
+   formats. Some V4L drivers respond to one, some to the other.
+
+.. [#f6]
+   Not to be confused with ``V4L2_PIX_FMT_YUV411P``, which is a planar
+   format.
+
+.. [#f7]
+   V4L explains this as: "RAW capture (BT848)"
+
+.. [#f8]
+   Not to be confused with ``V4L2_PIX_FMT_Y41P``, which is a packed
+   format.
+
+.. [#f9]
+   Old driver versions used different values, eventually the custom
+   ``BTTV_VBISIZE`` ioctl was added to query the correct values.

+************************************
+Streaming I/O (DMA buffer importing)
+************************************
+
+The DMABUF framework provides a generic method for sharing buffers
+between multiple devices. Device drivers that support DMABUF can export
+a DMA buffer to userspace as a file descriptor (known as the exporter
+role), import a DMA buffer from userspace using a file descriptor
+previously exported for a different or the same device (known as the
+importer role), or both. This section describes the DMABUF importer role
+API in V4L2.
+
+Refer to :ref:`DMABUF exporting <VIDIOC_EXPBUF>` for details about
+exporting V4L2 buffers as DMABUF file descriptors.
+
+Input and output devices support the streaming I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>` ioctl is set. Whether
+importing DMA buffers through DMABUF file descriptors is supported is
+determined by calling the :ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+ioctl with the memory type set to ``V4L2_MEMORY_DMABUF``.
+
+This I/O method is dedicated to sharing DMA buffers between different
+devices, which may be V4L devices or other video-related devices (e.g.
+DRM). Buffers (planes) are allocated by a driver on behalf of an
+application. Next, these buffers are exported to the application as file
+descriptors using an API which is specific for an allocator driver. Only
+such file descriptor are exchanged. The descriptors and meta-information
+are passed in struct :c:type:`v4l2_buffer` (or in struct
+:c:type:`v4l2_plane` in the multi-planar API case). The
+driver must be switched into DMABUF I/O mode by calling the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>` with the desired buffer type.
+
+
+Example: Initiating streaming I/O with DMABUF file descriptors
+==============================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset(&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_DMABUF;
+    reqbuf.count = 1;
+
+    if (ioctl(fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf("Video capturing or DMABUF streaming is not supported\\n");
+	else
+	    perror("VIDIOC_REQBUFS");
+
+	exit(EXIT_FAILURE);
+    }
+
+The buffer (plane) file descriptor is passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. In case of multiplanar
+buffers, every plane can be associated with a different DMABUF
+descriptor. Although buffers are commonly cycled, applications can pass
+a different DMABUF descriptor at each :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call.
+
+Example: Queueing DMABUF using single plane API
+===============================================
+
+.. code-block:: c
+
+    int buffer_queue(int v4lfd, int index, int dmafd)
+    {
+	struct v4l2_buffer buf;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.fd = dmafd;
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Example 3.6. Queueing DMABUF using multi plane API
+==================================================
+
+.. code-block:: c
+
+    int buffer_queue_mp(int v4lfd, int index, int dmafd[], int n_planes)
+    {
+	struct v4l2_buffer buf;
+	struct v4l2_plane planes[VIDEO_MAX_PLANES];
+	int i;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.planes = planes;
+	buf.length = n_planes;
+
+	memset(&planes, 0, sizeof planes);
+
+	for (i = 0; i < n_planes; ++i)
+	    buf.m.planes[i].m.fd = dmafd[i];
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Captured or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+buffer at any time between the completion of the DMA and this ioctl. The
+memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, or when the device is closed.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions are always available.
+
+To start and stop capturing or displaying applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls.
+
+.. note::
+
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing DMABUF importing I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON
+<VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls,
+and the :ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.

+Digital Video (DV) Timings
+**************************
+
+The video standards discussed so far have been dealing with Analog TV
+and the corresponding video timings. Today there are many more different
+hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
+DVI connectors etc., that carry video signals and there is a need to
+extend the API to select the video timings for these interfaces. Since
+it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
+due to the limited bits available, a new set of ioctls was added to
+set/get video timings at the input and output.
+
+These ioctls deal with the detailed digital video timings that define
+each video format. This includes parameters such as the active video
+width and height, signal polarities, frontporches, backporches, sync
+widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
+the timings of the formats in the :ref:`cea861` and :ref:`vesadmt`

+==================
+
+``V4L2_CID_CAMERA_CLASS (class)``
+    The Camera class descriptor. Calling
+    :ref:`VIDIOC_QUERYCTRL` for this control will
+    return a description of this control class.
+
+.. _v4l2-exposure-auto-type:
+
+``V4L2_CID_EXPOSURE_AUTO``
+    (enum)
+
+enum v4l2_exposure_auto_type -
+    Enables automatic adjustments of the exposure time and/or iris
+    aperture. The effect of manual changes of the exposure time or iris
+    aperture while these features are enabled is undefined, drivers
+    should ignore such requests. Possible values are:
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_EXPOSURE_AUTO``
+      - Automatic exposure time, automatic iris aperture.
+    * - ``V4L2_EXPOSURE_MANUAL``
+      - Manual exposure time, manual iris.
+    * - ``V4L2_EXPOSURE_SHUTTER_PRIORITY``
+      - Manual exposure time, auto iris.
+    * - ``V4L2_EXPOSURE_APERTURE_PRIORITY``
+      - Auto exposure time, manual iris.
+
+
+
+``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
+    Determines the exposure time of the camera sensor. The exposure time
+    is limited by the frame interval. Drivers should interpret the
+    values as 100 µs units, where the value 1 stands for 1/10000th of a
+    second, 10000 for 1 second and 100000 for 10 seconds.
+
+``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
+    When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or
+    ``APERTURE_PRIORITY``, this control determines if the device may
+    dynamically vary the frame rate. By default this feature is disabled
+    (0) and the frame rate must remain constant.
+
+``V4L2_CID_AUTO_EXPOSURE_BIAS (integer menu)``
+    Determines the automatic exposure compensation, it is effective only
+    when ``V4L2_CID_EXPOSURE_AUTO`` control is set to ``AUTO``,
+    ``SHUTTER_PRIORITY`` or ``APERTURE_PRIORITY``. It is expressed in
+    terms of EV, drivers should interpret the values as 0.001 EV units,
+    where the value 1000 stands for +1 EV.
+
+    Increasing the exposure compensation value is equivalent to
+    decreasing the exposure value (EV) and will increase the amount of
+    light at the image sensor. The camera performs the exposure
+    compensation by adjusting absolute exposure time and/or aperture.
+
+.. _v4l2-exposure-metering:
+
+``V4L2_CID_EXPOSURE_METERING``
+    (enum)
+
+enum v4l2_exposure_metering -
+    Determines how the camera measures the amount of light available for
+    the frame exposure. Possible values are:
+
+.. tabularcolumns:: |p{8.7cm}|p{8.8cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_EXPOSURE_METERING_AVERAGE``
+      - Use the light information coming from the entire frame and average
+	giving no weighting to any particular portion of the metered area.
+    * - ``V4L2_EXPOSURE_METERING_CENTER_WEIGHTED``
+      - Average the light information coming from the entire frame giving
+	priority to the center of the metered area.
+    * - ``V4L2_EXPOSURE_METERING_SPOT``
+      - Measure only very small area at the center of the frame.
+    * - ``V4L2_EXPOSURE_METERING_MATRIX``
+      - A multi-zone metering. The light intensity is measured in several
+	points of the frame and the results are combined. The algorithm of
+	the zones selection and their significance in calculating the
+	final value is device dependent.
+
+
+
+``V4L2_CID_PAN_RELATIVE (integer)``
+    This control turns the camera horizontally by the specified amount.
+    The unit is undefined. A positive value moves the camera to the
+    right (clockwise when viewed from above), a negative value to the
+    left. A value of zero does not cause motion. This is a write-only
+    control.
+
+``V4L2_CID_TILT_RELATIVE (integer)``
+    This control turns the camera vertically by the specified amount.
+    The unit is undefined. A positive value moves the camera up, a
+    negative value down. A value of zero does not cause motion. This is
+    a write-only control.
+
+``V4L2_CID_PAN_RESET (button)``
+    When this control is set, the camera moves horizontally to the
+    default position.
+
+``V4L2_CID_TILT_RESET (button)``
+    When this control is set, the camera moves vertically to the default
+    position.
+
+``V4L2_CID_PAN_ABSOLUTE (integer)``
+    This control turns the camera horizontally to the specified
+    position. Positive values move the camera to the right (clockwise
+    when viewed from above), negative values to the left. Drivers should
+    interpret the values as arc seconds, with valid values between -180
+    * 3600 and +180 * 3600 inclusive.
+
+``V4L2_CID_TILT_ABSOLUTE (integer)``
+    This control turns the camera vertically to the specified position.
+    Positive values move the camera up, negative values down. Drivers
+    should interpret the values as arc seconds, with valid values
+    between -180 * 3600 and +180 * 3600 inclusive.
+
+``V4L2_CID_FOCUS_ABSOLUTE (integer)``
+    This control sets the focal point of the camera to the specified
+    position. The unit is undefined. Positive values set the focus
+    closer to the camera, negative values towards infinity.
+
+``V4L2_CID_FOCUS_RELATIVE (integer)``
+    This control moves the focal point of the camera by the specified
+    amount. The unit is undefined. Positive values move the focus closer
+    to the camera, negative values towards infinity. This is a
+    write-only control.
+
+``V4L2_CID_FOCUS_AUTO (boolean)``
+    Enables continuous automatic focus adjustments. The effect of manual
+    focus adjustments while this feature is enabled is undefined,
+    drivers should ignore such requests.
+
+``V4L2_CID_AUTO_FOCUS_START (button)``
+    Starts single auto focus process. The effect of setting this control
+    when ``V4L2_CID_FOCUS_AUTO`` is set to ``TRUE`` (1) is undefined,
+    drivers should ignore such requests.
+
+``V4L2_CID_AUTO_FOCUS_STOP (button)``
+    Aborts automatic focusing started with ``V4L2_CID_AUTO_FOCUS_START``
+    control. It is effective only when the continuous autofocus is
+    disabled, that is when ``V4L2_CID_FOCUS_AUTO`` control is set to
+    ``FALSE`` (0).
+
+.. _v4l2-auto-focus-status:
+
+``V4L2_CID_AUTO_FOCUS_STATUS (bitmask)``
+    The automatic focus status. This is a read-only control.
+
+    Setting ``V4L2_LOCK_FOCUS`` lock bit of the ``V4L2_CID_3A_LOCK``
+    control may stop updates of the ``V4L2_CID_AUTO_FOCUS_STATUS``
+    control value.
+
+.. tabularcolumns:: |p{6.7cm}|p{10.8cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_AUTO_FOCUS_STATUS_IDLE``
+      - Automatic focus is not active.
+    * - ``V4L2_AUTO_FOCUS_STATUS_BUSY``
+      - Automatic focusing is in progress.
+    * - ``V4L2_AUTO_FOCUS_STATUS_REACHED``
+      - Focus has been reached.
+    * - ``V4L2_AUTO_FOCUS_STATUS_FAILED``
+      - Automatic focus has failed, the driver will not transition from
+	this state until another action is performed by an application.
+
+
+
+.. _v4l2-auto-focus-range:
+
+``V4L2_CID_AUTO_FOCUS_RANGE``
+    (enum)
+
+enum v4l2_auto_focus_range -
+    Determines auto focus distance range for which lens may be adjusted.
+
+.. tabularcolumns:: |p{6.8cm}|p{10.7cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_AUTO_FOCUS_RANGE_AUTO``
+      - The camera automatically selects the focus range.
+    * - ``V4L2_AUTO_FOCUS_RANGE_NORMAL``
+      - Normal distance range, limited for best automatic focus
+	performance.
+    * - ``V4L2_AUTO_FOCUS_RANGE_MACRO``
+      - Macro (close-up) auto focus. The camera will use its minimum
+	possible distance for auto focus.
+    * - ``V4L2_AUTO_FOCUS_RANGE_INFINITY``
+      - The lens is set to focus on an object at infinite distance.
+
+
+
+``V4L2_CID_ZOOM_ABSOLUTE (integer)``
+    Specify the objective lens focal length as an absolute value. The
+    zoom unit is driver-specific and its value should be a positive
+    integer.
+
+``V4L2_CID_ZOOM_RELATIVE (integer)``
+    Specify the objective lens focal length relatively to the current
+    value. Positive values move the zoom lens group towards the
+    telephoto direction, negative values towards the wide-angle
+    direction. The zoom unit is driver-specific. This is a write-only
+    control.
+
+``V4L2_CID_ZOOM_CONTINUOUS (integer)``
+    Move the objective lens group at the specified speed until it
+    reaches physical device limits or until an explicit request to stop
+    the movement. A positive value moves the zoom lens group towards the
+    telephoto direction. A value of zero stops the zoom lens group
+    movement. A negative value moves the zoom lens group towards the
+    wide-angle direction. The zoom speed unit is driver-specific.
+
+``V4L2_CID_IRIS_ABSOLUTE (integer)``
+    This control sets the camera's aperture to the specified value. The
+    unit is undefined. Larger values open the iris wider, smaller values
+    close it.
+
+``V4L2_CID_IRIS_RELATIVE (integer)``
+    This control modifies the camera's aperture by the specified amount.
+    The unit is undefined. Positive values open the iris one step
+    further, negative values close it one step further. This is a
+    write-only control.
+
+``V4L2_CID_PRIVACY (boolean)``
+    Prevent video from being acquired by the camera. When this control
+    is set to ``TRUE`` (1), no image can be captured by the camera.
+    Common means to enforce privacy are mechanical obturation of the
+    sensor and firmware image processing, but the device is not
+    restricted to these methods. Devices that implement the privacy
+    control must support read access and may support write access.
+
+``V4L2_CID_BAND_STOP_FILTER (integer)``
+    Switch the band-stop filter of a camera sensor on or off, or specify
+    its strength. Such band-stop filters can be used, for example, to
+    filter out the fluorescent light component.
+
+.. _v4l2-auto-n-preset-white-balance:
+
+``V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE``
+    (enum)
+
+enum v4l2_auto_n_preset_white_balance -
+    Sets white balance to automatic, manual or a preset. The presets
+    determine color temperature of the light as a hint to the camera for
+    white balance adjustments resulting in most accurate color
+    representation. The following white balance presets are listed in
+    order of increasing color temperature.
+
+.. tabularcolumns:: |p{7.2 cm}|p{10.3cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_WHITE_BALANCE_MANUAL``
+      - Manual white balance.
+    * - ``V4L2_WHITE_BALANCE_AUTO``
+      - Automatic white balance adjustments.
+    * - ``V4L2_WHITE_BALANCE_INCANDESCENT``
+      - White balance setting for incandescent (tungsten) lighting. It
+	generally cools down the colors and corresponds approximately to
+	2500...3500 K color temperature range.
+    * - ``V4L2_WHITE_BALANCE_FLUORESCENT``
+      - White balance preset for fluorescent lighting. It corresponds
+	approximately to 4000...5000 K color temperature.
+    * - ``V4L2_WHITE_BALANCE_FLUORESCENT_H``
+      - With this setting the camera will compensate for fluorescent H
+	lighting.
+    * - ``V4L2_WHITE_BALANCE_HORIZON``
+      - White balance setting for horizon daylight. It corresponds
+	approximately to 5000 K color temperature.
+    * - ``V4L2_WHITE_BALANCE_DAYLIGHT``
+      - White balance preset for daylight (with clear sky). It corresponds
+	approximately to 5000...6500 K color temperature.
+    * - ``V4L2_WHITE_BALANCE_FLASH``
+      - With this setting the camera will compensate for the flash light.
+	It slightly warms up the colors and corresponds roughly to
+	5000...5500 K color temperature.
+    * - ``V4L2_WHITE_BALANCE_CLOUDY``
+      - White balance preset for moderately overcast sky. This option
+	corresponds approximately to 6500...8000 K color temperature
+	range.
+    * - ``V4L2_WHITE_BALANCE_SHADE``
+      - White balance preset for shade or heavily overcast sky. It
+	corresponds approximately to 9000...10000 K color temperature.
+
+
+
+.. _v4l2-wide-dynamic-range:
+
+``V4L2_CID_WIDE_DYNAMIC_RANGE (boolean)``
+    Enables or disables the camera's wide dynamic range feature. This
+    feature allows to obtain clear images in situations where intensity
+    of the illumination varies significantly throughout the scene, i.e.
+    there are simultaneously very dark and very bright areas. It is most
+    commonly realized in cameras by combining two subsequent frames with
+    different exposure times.  [#f1]_
+
+.. _v4l2-image-stabilization:
+
+``V4L2_CID_IMAGE_STABILIZATION (boolean)``
+    Enables or disables image stabilization.
+
+``V4L2_CID_ISO_SENSITIVITY (integer menu)``
+    Determines ISO equivalent of an image sensor indicating the sensor's
+    sensitivity to light. The numbers are expressed in arithmetic scale,
+    as per :ref:`iso12232` standard, where doubling the sensor
+    sensitivity is represented by doubling the numerical ISO value.
+    Applications should interpret the values as standard ISO values
+    multiplied by 1000, e.g. control value 800 stands for ISO 0.8.
+    Drivers will usually support only a subset of standard ISO values.
+    The effect of setting this control while the
+    ``V4L2_CID_ISO_SENSITIVITY_AUTO`` control is set to a value other
+    than ``V4L2_CID_ISO_SENSITIVITY_MANUAL`` is undefined, drivers
+    should ignore such requests.
+
+.. _v4l2-iso-sensitivity-auto-type:
+
+``V4L2_CID_ISO_SENSITIVITY_AUTO``
+    (enum)
+
+enum v4l2_iso_sensitivity_type -
+    Enables or disables automatic ISO sensitivity adjustments.
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_CID_ISO_SENSITIVITY_MANUAL``
+      - Manual ISO sensitivity.
+    * - ``V4L2_CID_ISO_SENSITIVITY_AUTO``
+      - Automatic ISO sensitivity adjustments.
+
+
+
+.. _v4l2-scene-mode:
+
+``V4L2_CID_SCENE_MODE``
+    (enum)
+
+enum v4l2_scene_mode -
+    This control allows to select scene programs as the camera automatic
+    modes optimized for common shooting scenes. Within these modes the
+    camera determines best exposure, aperture, focusing, light metering,
+    white balance and equivalent sensitivity. The controls of those
+    parameters are influenced by the scene mode control. An exact
+    behavior in each mode is subject to the camera specification.
+
+    When the scene mode feature is not used, this control should be set
+    to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related
+    controls are accessible. The following scene programs are defined:
+
+.. raw:: latex
+
+    \small
+
+.. tabularcolumns:: |p{5.9cm}|p{11.5cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_SCENE_MODE_NONE``
+      - The scene mode feature is disabled.
+    * - ``V4L2_SCENE_MODE_BACKLIGHT``
+      - Backlight. Compensates for dark shadows when light is coming from
+	behind a subject, also by automatically turning on the flash.
+    * - ``V4L2_SCENE_MODE_BEACH_SNOW``
+      - Beach and snow. This mode compensates for all-white or bright
+	scenes, which tend to look gray and low contrast, when camera's
+	automatic exposure is based on an average scene brightness. To
+	compensate, this mode automatically slightly overexposes the
+	frames. The white balance may also be adjusted to compensate for
+	the fact that reflected snow looks bluish rather than white.
+    * - ``V4L2_SCENE_MODE_CANDLELIGHT``
+      - Candle light. The camera generally raises the ISO sensitivity and
+	lowers the shutter speed. This mode compensates for relatively
+	close subject in the scene. The flash is disabled in order to
+	preserve the ambiance of the light.
+    * - ``V4L2_SCENE_MODE_DAWN_DUSK``
+      - Dawn and dusk. Preserves the colors seen in low natural light
+	before dusk and after down. The camera may turn off the flash, and
+	automatically focus at infinity. It will usually boost saturation
+	and lower the shutter speed.
+    * - ``V4L2_SCENE_MODE_FALL_COLORS``
+      - Fall colors. Increases saturation and adjusts white balance for
+	color enhancement. Pictures of autumn leaves get saturated reds
+	and yellows.
+    * - ``V4L2_SCENE_MODE_FIREWORKS``
+      - Fireworks. Long exposure times are used to capture the expanding
+	burst of light from a firework. The camera may invoke image
+	stabilization.
+    * - ``V4L2_SCENE_MODE_LANDSCAPE``
+      - Landscape. The camera may choose a small aperture to provide deep
+	depth of field and long exposure duration to help capture detail
+	in dim light conditions. The focus is fixed at infinity. Suitable
+	for distant and wide scenery.
+    * - ``V4L2_SCENE_MODE_NIGHT``
+      - Night, also known as Night Landscape. Designed for low light
+	conditions, it preserves detail in the dark areas without blowing
+	out bright objects. The camera generally sets itself to a
+	medium-to-high ISO sensitivity, with a relatively long exposure
+	time, and turns flash off. As such, there will be increased image
+	noise and the possibility of blurred image.
+    * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
+      - Party and indoor. Designed to capture indoor scenes that are lit
+	by indoor background lighting as well as the flash. The camera
+	usually increases ISO sensitivity, and adjusts exposure for the
+	low light conditions.
+    * - ``V4L2_SCENE_MODE_PORTRAIT``
+      - Portrait. The camera adjusts the aperture so that the depth of
+	field is reduced, which helps to isolate the subject against a
+	smooth background. Most cameras recognize the presence of faces in
+	the scene and focus on them. The color hue is adjusted to enhance
+	skin tones. The intensity of the flash is often reduced.
+    * - ``V4L2_SCENE_MODE_SPORTS``
+      - Sports. Significantly increases ISO and uses a fast shutter speed
+	to freeze motion of rapidly-moving subjects. Increased image noise
+	may be seen in this mode.
+    * - ``V4L2_SCENE_MODE_SUNSET``
+      - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
+	up the saturation.
+    * - ``V4L2_SCENE_MODE_TEXT``
+      - Text. It applies extra contrast and sharpness, it is typically a
+	black-and-white mode optimized for readability. Automatic focus
+	may be switched to close-up mode and this setting may also involve
+	some lens-distortion correction.
+
+.. raw:: latex
+
+    \normalsize
+
+
+``V4L2_CID_3A_LOCK (bitmask)``
+    This control locks or unlocks the automatic focus, exposure and
+    white balance. The automatic adjustments can be paused independently
+    by setting the corresponding lock bit to 1. The camera then retains
+    the settings until the lock bit is cleared. The following lock bits
+    are defined:
+
+    When a given algorithm is not enabled, drivers should ignore
+    requests to lock it and should return no error. An example might be
+    an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
+    ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
+    value of this control may be changed by exposure, white balance or
+    focus controls.
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_LOCK_EXPOSURE``
+      - Automatic exposure adjustments lock.
+    * - ``V4L2_LOCK_WHITE_BALANCE``
+      - Automatic white balance adjustments lock.
+    * - ``V4L2_LOCK_FOCUS``
+      - Automatic focus lock.
+
+
+
+``V4L2_CID_PAN_SPEED (integer)``
+    This control turns the camera horizontally at the specific speed.
+    The unit is undefined. A positive value moves the camera to the
+    right (clockwise when viewed from above), a negative value to the
+    left. A value of zero stops the motion if one is in progress and has
+    no effect otherwise.
+
+``V4L2_CID_TILT_SPEED (integer)``
+    This control turns the camera vertically at the specified speed. The
+    unit is undefined. A positive value moves the camera up, a negative
+    value down. A value of zero stops the motion if one is in progress
+    and has no effect otherwise.
+
+``V4L2_CID_CAMERA_ORIENTATION (menu)``
+    This read-only control describes the camera orientation by reporting its
+    mounting position on the device where the camera is installed. The control
+    value is constant and not modifiable by software. This control is
+    particularly meaningful for devices which have a well defined orientation,
+    such as phones, laptops and portable devices since the control is expressed
+    as a position relative to the device's intended usage orientation. For
+    example, a camera installed on the user-facing side of a phone, a tablet or
+    a laptop device is said to be have ``V4L2_CAMERA_ORIENTATION_FRONT``
+    orientation, while a camera installed on the opposite side of the front one
+    is said to be have ``V4L2_CAMERA_ORIENTATION_BACK`` orientation. Camera
+    sensors not directly attached to the device, or attached in a way that
+    allows them to move freely, such as webcams and digital cameras, are said to
+    have the ``V4L2_CAMERA_ORIENTATION_EXTERNAL`` orientation.
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+

+      - The camera is oriented towards the user facing side of the device.
+    * - ``V4L2_CAMERA_ORIENTATION_BACK``
+      - The camera is oriented towards the back facing side of the device.
+    * - ``V4L2_CAMERA_ORIENTATION_EXTERNAL``
+      - The camera is not directly attached to the device and is freely movable.
+
+
+
+``V4L2_CID_CAMERA_SENSOR_ROTATION (integer)``
+    This read-only control describes the rotation correction in degrees in the
+    counter-clockwise direction to be applied to the captured images once
+    captured to memory to compensate for the camera sensor mounting rotation.
+
+    For a precise definition of the sensor mounting rotation refer to the
+    extensive description of the 'rotation' properties in the device tree
+    bindings file 'video-interfaces.txt'.
+
+    A few examples are below reported, using a shark swimming from left to
+    right in front of the user as the example scene to capture. ::

+    Example one - Webcam
+
+    Assuming you can bring your laptop with you while swimming with sharks,
+    the camera module of the laptop is installed on the user facing part of a
+    laptop screen casing, and is typically used for video calls. The captured
+    images are meant to be displayed in landscape mode (width > height) on the
+    laptop screen.
+
+    The camera is typically mounted upside-down to compensate the lens optical
+    inversion effect. In this case the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION control is 0, no rotation is required to
+    display images correctly to the user.
+
+    If the camera sensor is not mounted upside-down it is required to compensate
+    the lens optical inversion effect and the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION control is 180 degrees, as images will
+    result rotated when captured to memory. ::

+
+    Example two - Phone camera
+
+    It is more handy to go and swim with sharks with only your mobile phone
+    with you and take pictures with the camera that is installed on the back
+    side of the device, facing away from the user. The captured images are meant
+    to be displayed in portrait mode (height > width) to match the device screen
+    orientation and the device usage orientation used when taking the picture.
+
+    The camera sensor is typically mounted with its pixel array longer side
+    aligned to the device longer side, upside-down mounted to compensate for
+    the lens optical inversion effect.
+
+    The images once captured to memory will be rotated and the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION will report a 90 degree rotation. ::

+MFC 5.1 MPEG Controls
+=====================
+
+The following MPEG class controls deal with MPEG decoding and encoding
+settings that are specific to the Multi Format Codec 5.1 device present
+in the S5P family of SoCs by Samsung.
+
+
+.. _mfc51-control-id:
+
+MFC 5.1 Control IDs
+-------------------
+
+``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE (boolean)``
+    If the display delay is enabled then the decoder is forced to return
+    a CAPTURE buffer (decoded frame) after processing a certain number
+    of OUTPUT buffers. The delay can be set through
+    ``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY``. This
+    feature can be used for example for generating thumbnails of videos.
+    Applicable to the H264 decoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY (integer)``
+    Display delay value for H264 decoder. The decoder is forced to
+    return a decoded frame after the set 'display delay' number of
+    frames. If this number is low it may result in frames returned out
+    of display order, in addition the hardware may still be using the
+    returned buffer as a reference picture for subsequent frames.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_NUM_REF_PIC_FOR_P (integer)``
+    The number of reference pictures used for encoding a P picture.
+    Applicable to the H264 encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_PADDING (boolean)``
+    Padding enable in the encoder - use a color instead of repeating
+    border pixels. Applicable to encoders.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_PADDING_YUV (integer)``
+    Padding color in the encoder. Applicable to encoders. The supplied
+    32-bit integer is interpreted as follows (bit 0 = least significant
+    bit):
+
+
+
+.. flat-table::

+      - Must be zero.
+
+
+
+``V4L2_CID_MPEG_MFC51_VIDEO_RC_REACTION_COEFF (integer)``
+    Reaction coefficient for MFC rate control. Applicable to encoders.
+
+    .. note::
+
+       #. Valid only when the frame level RC is enabled.
+
+       #. For tight CBR, this field must be small (ex. 2 ~ 10). For
+	  VBR, this field must be large (ex. 100 ~ 1000).
+
+       #. It is not recommended to use the greater number than
+	  FRAME_RATE * (10^9 / BIT_RATE).
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_DARK (boolean)``
+    Adaptive rate control for dark region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_SMOOTH (boolean)``
+    Adaptive rate control for smooth region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_STATIC (boolean)``
+    Adaptive rate control for static region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_ACTIVITY (boolean)``
+    Adaptive rate control for activity region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+.. _v4l2-mpeg-mfc51-video-frame-skip-mode:
+
+``V4L2_CID_MPEG_MFC51_VIDEO_FRAME_SKIP_MODE``
+    (enum)
+
+enum v4l2_mpeg_mfc51_video_frame_skip_mode -
+    Indicates in what conditions the encoder should skip frames. If
+    encoding a frame would cause the encoded stream to be larger then a
+    chosen data limit then the frame will be skipped. Possible values
+    are:
+
+
+.. tabularcolumns:: |p{9.2cm}|p{8.3cm}|
+
+.. raw:: latex
+
+    \small

+
+.. raw:: latex
+
+    \normalsize
+
+``V4L2_CID_MPEG_MFC51_VIDEO_RC_FIXED_TARGET_BIT (integer)``
+    Enable rate-control with fixed target bit. If this setting is
+    enabled, then the rate control logic of the encoder will calculate
+    the average bitrate for a GOP and keep it below or equal the set
+    bitrate target. Otherwise the rate control logic calculates the
+    overall average bitrate for the stream and keeps it below or equal
+    to the set bitrate. In the first case the average bitrate for the
+    whole stream will be smaller then the set bitrate. This is caused
+    because the average is calculated for smaller number of frames, on
+    the other hand enabling this setting will ensure that the stream
+    will meet tight bandwidth constraints. Applicable to encoders.

+*******************************
+Digital Video Control Reference
+*******************************
+
+The Digital Video control class is intended to control receivers and
+transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
+`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
+(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
+(:ref:`dp`). These controls are generally expected to be private to
+the receiver or transmitter subdevice that implements them, so they are
+only exposed on the ``/dev/v4l-subdev*`` device node.
+
+.. note::
+
+   Note that these devices can have multiple input or output pads which are
+   hooked up to e.g. HDMI connectors. Even though the subdevice will
+   receive or transmit video from/to only one of those pads, the other pads
+   can still be active when it comes to EDID (Extended Display
+   Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
+   Content Protection System, :ref:`hdcp`) processing, allowing the
+   device to do the fairly slow EDID/HDCP handling in advance. This allows
+   for quick switching between connectors.
+
+These pads appear in several of the controls in this section as
+bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
+1, etc. The maximum value of the control is the set of valid pads.
+
+
+.. _dv-control-id:
+
+Digital Video Control IDs
+=========================
+
+``V4L2_CID_DV_CLASS (class)``
+    The Digital Video class descriptor.
+
+``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
+    Many connectors have a hotplug pin which is high if EDID information
+    is available from the source. This control shows the state of the
+    hotplug pin as seen by the transmitter. Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not have an
+    associated hotplug pin, then the bit for that pad will be 0. This
+    read-only control is applicable to DVI-D, HDMI and DisplayPort
+    connectors.
+
+``V4L2_CID_DV_TX_RXSENSE (bitmask)``
+    Rx Sense is the detection of pull-ups on the TMDS clock lines. This
+    normally means that the sink has left/entered standby (i.e. the
+    transmitter can sense that the receiver is ready to receive video).
+    Each bit corresponds to an output pad on the transmitter. If an
+    output pad does not have an associated Rx Sense, then the bit for
+    that pad will be 0. This read-only control is applicable to DVI-D
+    and HDMI devices.
+
+``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
+    When the transmitter sees the hotplug signal from the receiver it
+    will attempt to read the EDID. If set, then the transmitter has read
+    at least the first block (= 128 bytes). Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not support
+    EDIDs, then the bit for that pad will be 0. This read-only control
+    is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_MODE``
+    (enum)
+
+enum v4l2_dv_tx_mode -
+    HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
+    mode (video + audio + auxiliary data). This control selects which
+    mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
+    This control is applicable to HDMI connectors.
+
+``V4L2_CID_DV_TX_RGB_RANGE``
+    (enum)
+
+enum v4l2_dv_rgb_range -
+    Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
+    follows the RGB quantization range specified in the standard for the
+    video interface (ie. :ref:`cea861` for HDMI).
+    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
+    standard to be compatible with sinks that have not implemented the
+    standard correctly (unfortunately quite common for HDMI and DVI-D).
+    Full range allows all possible values to be used whereas limited
+    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
+    the number of bits per component. This control is applicable to VGA,
+    DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
+    (enum)
+
+enum v4l2_dv_it_content_type -
+    Configures the IT Content Type of the transmitted video. This
+    information is sent over HDMI and DisplayPort connectors as part of
+    the AVI InfoFrame. The term 'IT Content' is used for content that
+    originates from a computer as opposed to content from a TV broadcast
+    or an analog source. The enum v4l2_dv_it_content_type defines
+    the possible content types:
+
+.. tabularcolumns:: |p{7.3cm}|p{10.4cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_DV_IT_CONTENT_TYPE_GRAPHICS``
+      - Graphics content. Pixel data should be passed unfiltered and
+	without analog reconstruction.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_PHOTO``
+      - Photo content. The content is derived from digital still pictures.
+	The content should be passed through with minimal scaling and
+	picture enhancements.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_CINEMA``
+      - Cinema content.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_GAME``
+      - Game content. Audio and video latency should be minimized.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
+      - No IT Content information is available and the ITC bit in the AVI
+	InfoFrame is set to 0.
+
+
+
+``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
+    Detects whether the receiver receives power from the source (e.g.
+    HDMI carries 5V on one of the pins). This is often used to power an
+    eeprom which contains EDID information, such that the source can
+    read the EDID even if the sink is in standby/power off. Each bit
+    corresponds to an input pad on the receiver. If an input pad
+    cannot detect whether power is present, then the bit for that pad
+    will be 0. This read-only control is applicable to DVI-D, HDMI and
+    DisplayPort connectors.
+
+``V4L2_CID_DV_RX_RGB_RANGE``
+    (enum)
+
+enum v4l2_dv_rgb_range -
+    Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO

+Flash Control Reference
+***********************
+
+The V4L2 flash controls are intended to provide generic access to flash
+controller devices. Flash controller devices are typically used in
+digital cameras.
+
+The interface can support both LED and xenon flash devices. As of
+writing this, there is no xenon flash driver using this interface.
+
+
+.. _flash-controls-use-cases:
+
+Supported use cases
+===================
+
+
+Unsynchronised LED flash (software strobe)
+------------------------------------------
+
+Unsynchronised LED flash is controlled directly by the host as the
+sensor. The flash must be enabled by the host before the exposure of the
+image starts and disabled once it ends. The host is fully responsible
+for the timing of the flash.
+
+Example of such device: Nokia N900.
+
+
+Synchronised LED flash (hardware strobe)
+----------------------------------------
+
+The synchronised LED flash is pre-programmed by the host (power and
+timeout) but controlled by the sensor through a strobe signal from the
+sensor to the flash.
+
+The sensor controls the flash duration and timing. This information
+typically must be made available to the sensor.
+
+
+LED flash as torch
+------------------
+
+LED flash may be used as torch in conjunction with another use case
+involving camera or individually.
+

+	V4L2_CID_FLASH_STROBE control.
+    * - ``V4L2_FLASH_STROBE_SOURCE_EXTERNAL``
+      - The flash strobe is triggered by an external source. Typically
+	this is a sensor, which makes it possible to synchronise the
+	flash strobe start to exposure start.
+
+
+
+``V4L2_CID_FLASH_STROBE (button)``
+    Strobe flash. Valid when V4L2_CID_FLASH_LED_MODE is set to
+    V4L2_FLASH_LED_MODE_FLASH and V4L2_CID_FLASH_STROBE_SOURCE
+    is set to V4L2_FLASH_STROBE_SOURCE_SOFTWARE. Setting this
+    control may not be possible in presence of some faults. See
+    V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_STROBE_STOP (button)``
+    Stop flash strobe immediately.
+
+``V4L2_CID_FLASH_STROBE_STATUS (boolean)``
+    Strobe status: whether the flash is strobing at the moment or not.
+    This is a read-only control.
+
+``V4L2_CID_FLASH_TIMEOUT (integer)``
+    Hardware timeout for flash. The flash strobe is stopped after this
+    period of time has passed from the start of the strobe.
+
+``V4L2_CID_FLASH_INTENSITY (integer)``
+    Intensity of the flash strobe when the flash LED is in flash mode
+    (V4L2_FLASH_LED_MODE_FLASH). The unit should be milliamps (mA)
+    if possible.
+
+``V4L2_CID_FLASH_TORCH_INTENSITY (integer)``
+    Intensity of the flash LED in torch mode
+    (V4L2_FLASH_LED_MODE_TORCH). The unit should be milliamps (mA)
+    if possible. Setting this control may not be possible in presence of
+    some faults. See V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_INDICATOR_INTENSITY (integer)``
+    Intensity of the indicator LED. The indicator LED may be fully
+    independent of the flash LED. The unit should be microamps (uA) if
+    possible.
+
+``V4L2_CID_FLASH_FAULT (bitmask)``
+    Faults related to the flash. The faults tell about specific problems
+    in the flash chip itself or the LEDs attached to it. Faults may
+    prevent further use of some of the flash controls. In particular,
+    V4L2_CID_FLASH_LED_MODE is set to V4L2_FLASH_LED_MODE_NONE
+    if the fault affects the flash LED. Exactly which faults have such

+    The FM_RX class descriptor. Calling
+    :ref:`VIDIOC_QUERYCTRL` for this control will
+    return a description of this control class.
+
+``V4L2_CID_RDS_RECEPTION (boolean)``
+    Enables/disables RDS reception by the radio tuner
+
+``V4L2_CID_RDS_RX_PTY (integer)``
+    Gets RDS Programme Type field. This encodes up to 31 pre-defined
+    programme types.
+
+``V4L2_CID_RDS_RX_PS_NAME (string)``
+    Gets the Programme Service name (PS_NAME). It is intended for

+
+``V4L2_CID_RDS_RX_RADIO_TEXT (string)``
+    Gets the Radio Text info. It is a textual description of what is
+    being broadcasted. RDS Radio Text can be applied when broadcaster
+    wishes to transmit longer PS names, programme-related information or
+    any other text. In these cases, RadioText can be used in addition to
+    ``V4L2_CID_RDS_RX_PS_NAME``. The encoding for Radio Text strings is
+    also fully described in Annex E of :ref:`iec62106`. The length of

+
+``V4L2_CID_RDS_RX_TRAFFIC_ANNOUNCEMENT (boolean)``
+    If set, then a traffic announcement is in progress.

+=========================
+
+``V4L2_CID_IMAGE_PROC_CLASS (class)``
+    The IMAGE_PROC class descriptor.
+
+``V4L2_CID_LINK_FREQ (integer menu)``
+    Data bus frequency. Together with the media bus pixel code, bus type
+    (clock cycles per sample), the data bus frequency defines the pixel
+    rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
+    elsewhere, if the device is not an image sensor). The frame rate can
+    be calculated from the pixel clock, image width and height and
+    horizontal and vertical blanking. While the pixel rate control may
+    be defined elsewhere than in the subdev containing the pixel array,
+    the frame rate cannot be obtained from that information. This is
+    because only on the pixel array it can be assumed that the vertical
+    and horizontal blanking information is exact: no other blanking is
+    allowed in the pixel array. The selection of frame rate is performed
+    by selecting the desired horizontal and vertical blanking. The unit
+    of this control is Hz.
+
+``V4L2_CID_PIXEL_RATE (64-bit integer)``
+    Pixel rate in the source pads of the subdev. This control is
+    read-only and its unit is pixels / second.
+
+``V4L2_CID_TEST_PATTERN (menu)``
+    Some capture/display/sensor devices have the capability to generate
+    test pattern images. These hardware specific test patterns can be
+    used to test if a device is working properly.
+
+``V4L2_CID_DEINTERLACING_MODE (menu)``
+    The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
+    driver specific and are documented in :ref:`uapi-v4l-drivers`.
+
+``V4L2_CID_DIGITAL_GAIN (integer)``
+    Digital gain is the value by which all colour components
+    are multiplied by. Typically the digital gain applied is the
+    control value divided by e.g. 0x100, meaning that to get no
+    digital gain the control value needs to be 0x100. The no-gain
+    configuration is also typically the default.

+RF Tuner Control Reference
+**************************
+
+The RF Tuner (RF_TUNER) class includes controls for common features of
+devices having RF tuner.
+
+In this context, RF tuner is radio receiver circuit between antenna and
+demodulator. It receives radio frequency (RF) from the antenna and
+converts that received signal to lower intermediate frequency (IF) or
+baseband frequency (BB). Tuners that could do baseband output are often
+called Zero-IF tuners. Older tuners were typically simple PLL tuners
+inside a metal box, while newer ones are highly integrated chips
+without a metal box "silicon tuners". These controls are mostly
+applicable for new feature rich silicon tuners, just because older
+tuners does not have much adjustable features.
+
+For more information about RF tuners see
+`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__
+and `RF front end <http://en.wikipedia.org/wiki/RF_front_end>`__

+
+``V4L2_CID_RF_TUNER_BANDWIDTH (integer)``
+    Filter(s) on tuner signal path are used to filter signal according
+    to receiving party needs. Driver configures filters to fulfill
+    desired bandwidth requirement. Used when
+    V4L2_CID_RF_TUNER_BANDWIDTH_AUTO is not set. Unit is in Hz. The

+    There may be both RF and LNA gain controls in the same device. The
+    range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_LNA_GAIN (integer)``
+    LNA (low noise amplifier) gain is first gain stage on the RF tuner
+    signal path. It is located very close to tuner antenna input. Used
+    when ``V4L2_CID_RF_TUNER_LNA_GAIN_AUTO`` is not set. See
+    ``V4L2_CID_RF_TUNER_RF_GAIN`` to understand how RF gain and LNA gain

+    driver-specific.
+
+``V4L2_CID_RF_TUNER_MIXER_GAIN (integer)``
+    Mixer gain is second gain stage on the RF tuner signal path. It is
+    located inside mixer block, where RF signal is down-converted by the
+    mixer. Used when ``V4L2_CID_RF_TUNER_MIXER_GAIN_AUTO`` is not set.
+    The range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_IF_GAIN (integer)``

+    are driver-specific.
+
+``V4L2_CID_RF_TUNER_PLL_LOCK (boolean)``
+    Is synthesizer PLL locked? RF tuner is receiving given frequency
+    when that control is set. This is a read-only control.

+Extended Controls API
+*********************
+
+
+Introduction
+============
+
+The control mechanism as originally designed was meant to be used for
+user settings (brightness, saturation, etc). However, it turned out to
+be a very useful model for implementing more complicated driver APIs
+where each driver implements only a subset of a larger API.
+
+The MPEG encoding API was the driving force behind designing and
+implementing this extended control mechanism: the MPEG standard is quite
+large and the currently supported hardware MPEG encoders each only
+implement a subset of this standard. Further more, many parameters
+relating to how the video is encoded into an MPEG stream are specific to
+the MPEG encoding chip since the MPEG standard only defines the format
+of the resulting MPEG stream, not how the video is actually encoded into
+that format.
+
+Unfortunately, the original control API lacked some features needed for
+these new uses and so it was extended into the (not terribly originally
+named) extended control API.
+
+Even though the MPEG encoding API was the first effort to use the
+Extended Control API, nowadays there are also other classes of Extended
+Controls, such as Camera Controls and FM Transmitter Controls. The
+Extended Controls API as well as all Extended Controls classes are
+described in the following text.
+
+
+The Extended Control API
+========================
+
+Three new ioctls are available:
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`. These ioctls act
+on arrays of controls (as opposed to the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls that act on a single
+control). This is needed since it is often required to atomically change
+several controls at once.
+
+Each of the new ioctls expects a pointer to a struct
+:c:type:`v4l2_ext_controls`. This structure
+contains a pointer to the control array, a count of the number of
+controls in that array and a control class. Control classes are used to
+group similar controls into a single class. For example, control class
+``V4L2_CTRL_CLASS_USER`` contains all user controls (i. e. all controls
+that can also be set using the old :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
+ioctl). Control class ``V4L2_CTRL_CLASS_MPEG`` contains all controls
+relating to MPEG encoding, etc.
+
+All controls in the control array must belong to the specified control
+class. An error is returned if this is not the case.
+
+It is also possible to use an empty control array (``count`` == 0) to check
+whether the specified control class is supported.
+
+The control array is a struct
+:c:type:`v4l2_ext_control` array. The
+struct :c:type:`v4l2_ext_control` is very similar to
+struct :c:type:`v4l2_control`, except for the fact that
+it also allows for 64-bit values and pointers to be passed.
+
+Since the struct :c:type:`v4l2_ext_control` supports
+pointers it is now also possible to have controls with compound types
+such as N-dimensional arrays and/or structures. You need to specify the
+``V4L2_CTRL_FLAG_NEXT_COMPOUND`` when enumerating controls to actually
+be able to see such compound controls. In other words, these controls
+with compound types should only be used programmatically.
+
+Since such compound controls need to expose more information about
+themselves than is possible with :ref:`VIDIOC_QUERYCTRL <VIDIOC_QUERYCTRL>`
+the :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
+particular, this ioctl gives the dimensions of the N-dimensional array if
+this control consists of more than one element.
+
+.. note::
+
+   #. It is important to realize that due to the flexibility of controls it is
+      necessary to check whether the control you want to set actually is
+      supported in the driver and what the valid range of values is. So use
+      :ref:`VIDIOC_QUERYCTRL` to check this.
+
+   #. It is possible that some of the menu indices in a control of
+      type ``V4L2_CTRL_TYPE_MENU`` may not be supported (``VIDIOC_QUERYMENU``
+      will return an error). A good example is the list of supported MPEG
+      audio bitrates. Some drivers only support one or two bitrates, others
+      support a wider range.
+
+All controls use machine endianness.
+
+
+Enumerating Extended Controls
+=============================
+
+The recommended way to enumerate over the extended controls is by using
+:ref:`VIDIOC_QUERYCTRL` in combination with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag:
+
+
+.. code-block:: c
+
+    struct v4l2_queryctrl qctrl;
+
+    qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl (fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The initial control ID is set to 0 ORed with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag. The ``VIDIOC_QUERYCTRL`` ioctl will
+return the first control with a higher ID than the specified one. When
+no such controls are found an error is returned.
+
+If you want to get all controls within a specific control class, then
+you can set the initial ``qctrl.id`` value to the control class and add
+an extra check to break out of the loop when a control of another
+control class is found:
+
+
+.. code-block:: c
+
+    qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl(fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
+	    break;
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The 32-bit ``qctrl.id`` value is subdivided into three bit ranges: the
+top 4 bits are reserved for flags (e. g. ``V4L2_CTRL_FLAG_NEXT_CTRL``)
+and are not actually part of the ID. The remaining 28 bits form the
+control ID, of which the most significant 12 bits define the control
+class and the least significant 16 bits identify the control within the
+control class. It is guaranteed that these last 16 bits are always
+non-zero for controls. The range of 0x1000 and up are reserved for
+driver-specific controls. The macro ``V4L2_CTRL_ID2CLASS(id)`` returns
+the control class ID based on a control ID.
+
+If the driver does not support extended controls, then
+``VIDIOC_QUERYCTRL`` will fail when used in combination with
+``V4L2_CTRL_FLAG_NEXT_CTRL``. In that case the old method of enumerating
+control should be used (see :ref:`enum_all_controls`). But if it is
+supported, then it is guaranteed to enumerate over all controls,
+including driver-private controls.
+
+
+Creating Control Panels
+=======================
+
+It is possible to create control panels for a graphical user interface
+where the user can select the various controls. Basically you will have
+to iterate over all controls using the method described above. Each
+control class starts with a control of type
+``V4L2_CTRL_TYPE_CTRL_CLASS``. ``VIDIOC_QUERYCTRL`` will return the name
+of this control class which can be used as the title of a tab page
+within a control panel.
+
+The flags field of struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` also
+contains hints on the behavior of the control. See the
+:ref:`VIDIOC_QUERYCTRL` documentation for more
+details.

+
+***********
+Field Order
+***********
+
+We have to distinguish between progressive and interlaced video.
+Progressive video transmits all lines of a video image sequentially.
+Interlaced video divides an image into two fields, containing only the
+odd and even lines of the image, respectively. Alternating the so called
+odd and even field are transmitted, and due to a small delay between
+fields a cathode ray TV displays the lines interleaved, yielding the
+original frame. This curious technique was invented because at refresh
+rates similar to film the image would fade out too quickly. Transmitting
+fields reduces the flicker without the necessity of doubling the frame
+rate and with it the bandwidth required for each channel.
+
+It is important to understand a video camera does not expose one frame
+at a time, merely transmitting the frames separated into fields. The
+fields are in fact captured at two different instances in time. An
+object on screen may well move between one field and the next. For
+applications analysing motion it is of paramount importance to recognize
+which field of a frame is older, the *temporal order*.
+
+When the driver provides or accepts images field by field rather than
+interleaved, it is also important applications understand how the fields
+combine to frames. We distinguish between top (aka odd) and bottom (aka
+even) fields, the *spatial order*: The first line of the top field is
+the first line of an interlaced frame, the first line of the bottom
+field is the second line of that frame.
+
+However because fields were captured one after the other, arguing
+whether a frame commences with the top or bottom field is pointless. Any
+two successive top and bottom, or bottom and top fields yield a valid
+frame. Only when the source was progressive to begin with, e. g. when
+transferring film to video, two fields may come from the same frame,
+creating a natural order.
+
+Counter to intuition the top field is not necessarily the older field.
+Whether the older field contains the top or bottom lines is a convention
+determined by the video standard. Hence the distinction between temporal
+and spatial order of fields. The diagrams below should make this
+clearer.
+
+In V4L it is assumed that all video cameras transmit fields on the media
+bus in the same order they were captured, so if the top field was
+captured first (is the older field), the top field is also transmitted
+first on the bus.
+
+All video capture and output devices must report the current field
+order. Some drivers may permit the selection of a different order, to
+this end applications initialize the ``field`` field of struct
+:c:type:`v4l2_pix_format` before calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. If this is not desired it
+should have the value ``V4L2_FIELD_ANY`` (0).

+
+    * - ``V4L2_FIELD_ANY``
+      - 0
+      - Applications request this field order when any field format
+	is acceptable. Drivers choose depending on hardware capabilities or
+	e.g. the requested image size, and return the actual field order.
+	Drivers must never return ``V4L2_FIELD_ANY``.
+	If multiple field orders are possible the
+	driver must choose one of the possible field orders during
+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
+	:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`. struct

+	``V4L2_FIELD_ANY``.
+    * - ``V4L2_FIELD_NONE``
+      - 1
+      - Images are in progressive (frame-based) format, not interlaced
+        (field-based).
+    * - ``V4L2_FIELD_TOP``
+      - 2
+      - Images consist of the top (aka odd) field only.
+    * - ``V4L2_FIELD_BOTTOM``
+      - 3
+      - Images consist of the bottom (aka even) field only. Applications
+	may wish to prevent a device from capturing interlaced images
+	because they will have "comb" or "feathering" artefacts around
+	moving objects.
+    * - ``V4L2_FIELD_INTERLACED``
+      - 4
+      - Images contain both fields, interleaved line by line. The temporal
+	order of the fields (whether the top or bottom field is older)
+	depends on the current video standard. In M/NTSC the bottom
+	field is the older field. In all other standards the top field
+	is the older field.
+    * - ``V4L2_FIELD_SEQ_TB``
+      - 5
+      - Images contain both fields, the top field lines are stored first
+	in memory, immediately followed by the bottom field lines. Fields
+	are always stored in temporal order, the older one first in
+	memory. Image sizes refer to the frame, not fields.
+    * - ``V4L2_FIELD_SEQ_BT``
+      - 6
+      - Images contain both fields, the bottom field lines are stored
+	first in memory, immediately followed by the top field lines.
+	Fields are always stored in temporal order, the older one first in
+	memory. Image sizes refer to the frame, not fields.
+    * - ``V4L2_FIELD_ALTERNATE``
+      - 7
+      - The two fields of a frame are passed in separate buffers, in
+	temporal order, i. e. the older one first. To indicate the field
+	parity (whether the current field is a top or bottom field) the
+	driver or application, depending on data direction, must set
+	struct :c:type:`v4l2_buffer` ``field`` to
+	``V4L2_FIELD_TOP`` or ``V4L2_FIELD_BOTTOM``. Any two successive
+	fields pair to build a frame. If fields are successive, without
+	any dropped fields between them (fields can drop individually),
+	can be determined from the struct
+	:c:type:`v4l2_buffer` ``sequence`` field. This
+	format cannot be selected when using the read/write I/O method
+	since there is no way to communicate if a field was a top or
+	bottom field.
+    * - ``V4L2_FIELD_INTERLACED_TB``
+      - 8
+      - Images contain both fields, interleaved line by line, top field
+	first. The top field is the older field.
+    * - ``V4L2_FIELD_INTERLACED_BT``

+Data Formats
+************
+
+
+Data Format Negotiation
+=======================
+
+Different devices exchange different kinds of data with applications,
+for example video images, raw or sliced VBI data, RDS datagrams. Even
+within one kind many different formats are possible, in particular there is an
+abundance of image formats. Although drivers must provide a default and
+the selection persists across closing and reopening a device,
+applications should always negotiate a data format before engaging in
+data exchange. Negotiation means the application asks for a particular
+format and the driver selects and reports the best the hardware can do
+to satisfy the request. Of course applications can also just query the
+current selection.
+
+A single mechanism exists to negotiate all data formats using the
+aggregate struct :c:type:`v4l2_format` and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls. Additionally the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to examine
+what the hardware *could* do, without actually selecting a new data
+format. The data formats supported by the V4L2 API are covered in the
+respective device section in :ref:`devices`. For a closer look at
+image formats see :ref:`pixfmt`.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl is a major turning-point in the
+initialization sequence. Prior to this point multiple panel applications
+can access the same device concurrently to select the current input,
+change controls or modify other properties. The first :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+assigns a logical stream (video data, VBI data etc.) exclusively to one
+file descriptor.
+
+Exclusive means no other application, more precisely no other file
+descriptor, can grab this stream or change device properties
+inconsistent with the negotiated parameters. A video standard change for
+example, when the new standard uses a different number of scan lines,
+can invalidate the selected image format. Therefore only the file
+descriptor owning the stream can make invalidating changes. Accordingly
+multiple file descriptors which grabbed different logical streams
+prevent each other from interfering with their settings. When for
+example video overlay is about to start or already in progress,
+simultaneous video capturing may be restricted to the same cropping and
+image size.
+
+When applications omit the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl its locking side
+effects are implied by the next step, the selection of an I/O method
+with the :ref:`VIDIOC_REQBUFS` ioctl or implicit
+with the first :ref:`read() <func-read>` or
+:ref:`write() <func-write>` call.
+
+Generally only one logical stream can be assigned to a file descriptor,
+the exception being drivers permitting simultaneous video capturing and
+overlay using the same file descriptor for compatibility with V4L and
+earlier versions of V4L2. Switching the logical stream or returning into
+"panel mode" is possible by closing and reopening the device. Drivers
+*may* support a switch using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+All drivers exchanging data with applications must support the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. Implementation of the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is highly recommended but optional.
+
+
+Image Format Enumeration
+========================
+
+Apart of the generic format negotiation functions a special ioctl to
+enumerate all image formats supported by video capture, overlay or
+output devices is available. [#f1]_
+
+The :ref:`VIDIOC_ENUM_FMT` ioctl must be supported
+by all drivers exchanging image data with applications.
+
+.. important::
+
+    Drivers are not supposed to convert image formats in kernel space.
+    They must enumerate only formats directly supported by the hardware.
+    If necessary driver writers should publish an example conversion
+    routine or library for integration into applications.
+
+.. [#f1]
+   Enumerating formats an application has no a-priori knowledge of
+   (otherwise it could explicitly ask for them and need not enumerate)
+   seems useless, but there are applications serving as proxy between
+   drivers and the actual video applications for which this is useful.

+
+
+Description
+===========
+
+The :ref:`ioctl() <func-ioctl>` function is used to program V4L2 devices. The
+argument ``fd`` must be an open file descriptor. An ioctl ``request``
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes. Macros and
+defines specifying V4L2 ioctl requests are located in the
+``videodev2.h`` header file. Applications should use their own copy, not
+include the version in the kernel sources on the system they compile on.
+All V4L2 ioctl requests, their respective function and parameters are
+specified in :ref:`user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+
+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+    :name: v4l2-mmap
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be the same value as
+    returned by the driver in the struct
+    :c:type:`v4l2_buffer` ``length`` field for the
+    single-planar API, and the same value as returned by the driver in
+    the struct :c:type:`v4l2_plane` ``length`` field for
+    the multi-planar API.
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+    .. note::
+
+      #. The Linux ``videobuf`` kernel module, which is used by some
+	 drivers supports only ``PROT_READ`` | ``PROT_WRITE``. When the
+	 driver does not support the desired protection, the
+	 :ref:`mmap() <func-mmap>` function fails.
+
+      #. Device memory accesses (e. g. the memory on a graphics card
+	 with video capturing hardware) may incur a performance penalty
+	 compared to main memory accesses, or reads may be significantly
+	 slower than writes or vice versa. Other I/O methods may be more
+	 efficient in such case.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <func-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note::
+
+       The Linux ``videobuf`` module  which is used by some
+       drivers supports only ``MAP_SHARED``. ``MAP_PRIVATE`` requests
+       copy-on-write semantics. V4L2 applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``offset``
+    Offset of the buffer in device memory. This must be the same value
+    as returned by the driver in the struct
+    :c:type:`v4l2_buffer` ``m`` union ``offset`` field for
+    the single-planar API, and the same value as returned by the driver
+    in the struct :c:type:`v4l2_plane` ``m`` union
+    ``mem_offset`` field for the multi-planar API.
+
+
+Description
+===========
+
+The :ref:`mmap() <func-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`VIDIOC_QUERYBUF` ioctl. Buffers must be
+allocated with the :ref:`VIDIOC_REQBUFS` ioctl
+before they can be queried.
+
+To unmap buffers the :ref:`munmap() <func-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <func-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.
+
+EACCES
+    ``fd`` is not open for reading and writing.
+
+EINVAL
+    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+    The ``flags`` or ``prot`` value is not supported.
+
+    No buffers have been allocated with the
+    :ref:`VIDIOC_REQBUFS` ioctl.
+
+ENOMEM
+    Not enough physical or virtual memory was available to complete the
+    request.

+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
+    :name: v4l2-poll
+
+Arguments
+=========
+
+
+
+Description
+===========
+
+With the :ref:`poll() <func-poll>` function applications can suspend execution
+until the driver has captured data or is ready to accept data for
+output.
+
+When streaming I/O has been negotiated this function waits until a
+buffer has been filled by the capture device and can be dequeued with
+the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. For output devices this
+function waits until the device is ready to accept a new buffer to be
+queued up with the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl for
+display. When buffers are already in the outgoing queue of the driver
+(capture) or the incoming queue isn't full (display) the function
+returns immediately.
+
+On success :ref:`poll() <func-poll>` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective :c:func:`struct pollfd` structure
+is non-zero). Capture devices set the ``POLLIN`` and ``POLLRDNORM``
+flags in the ``revents`` field, output devices the ``POLLOUT`` and
+``POLLWRNORM`` flags. When the function timed out it returns a value of
+zero, on failure it returns -1 and the ``errno`` variable is set
+appropriately. When the application did not call
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` the :ref:`poll() <func-poll>`
+function succeeds, but sets the ``POLLERR`` flag in the ``revents``
+field. When the application has called
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` for a capture device but
+hasn't yet called :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, the
+:ref:`poll() <func-poll>` function succeeds and sets the ``POLLERR`` flag in
+the ``revents`` field. For output devices this same situation will cause
+:ref:`poll() <func-poll>` to succeed as well, but it sets the ``POLLOUT`` and
+``POLLWRNORM`` flags in the ``revents`` field.
+
+If an event occurred (see :ref:`VIDIOC_DQEVENT`)
+then ``POLLPRI`` will be set in the ``revents`` field and
+:ref:`poll() <func-poll>` will return.
+
+When use of the :ref:`read() <func-read>` function has been negotiated and the
+driver does not capture yet, the :ref:`poll() <func-poll>` function starts
+capturing. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until data has been captured and can be read. When the driver
+captures continuously (as opposed to, for example, still images) the
+function may return immediately.
+
+When use of the :ref:`write() <func-write>` function has been negotiated and the
+driver does not stream yet, the :ref:`poll() <func-poll>` function starts
+streaming. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until the driver is ready for a non-blocking
+:ref:`write() <func-write>` call.
+
+If the caller is only interested in events (just ``POLLPRI`` is set in
+the ``events`` field), then :ref:`poll() <func-poll>` will *not* start
+streaming if the driver does not stream yet. This makes it possible to
+just poll for events and not for buffers.
+
+All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
+function or streaming I/O must also support the :ref:`poll() <func-poll>`
+function.
+
+For more details see the :ref:`poll() <func-poll>` manual page.
+
+
+Return Value
+============
+
+On success, :ref:`poll() <func-poll>` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+EBADF
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+EBUSY
+    The driver does not support multiple read or write streams and the
+    device is already in use.
+
+EFAULT
+    ``ufds`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal.
+
+EINVAL
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+.. c:function:: ssize_t read( int fd, void *buf, size_t count )
+    :name: v4l2-read
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``buf``
+   Buffer to be filled
+
+``count``
+  Max number of bytes to read
+
+Description
+===========
+
+:ref:`read() <func-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``. The layout of the
+data in the buffer is discussed in the respective device interface
+section, see ##. If ``count`` is zero, :ref:`read() <func-read>` returns zero
+and has no other results. If ``count`` is greater than ``SSIZE_MAX``,
+the result is unspecified. Regardless of the ``count`` value each
+:ref:`read() <func-read>` call will provide at most one frame (two fields)
+worth of data.
+
+By default :ref:`read() <func-read>` blocks until data becomes available. When
+the ``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>`
+function it returns immediately with an ``EAGAIN`` error code when no data
+is available. The :ref:`select() <func-select>` or
+:ref:`poll() <func-poll>` functions can always be used to suspend
+execution until data becomes available. All drivers supporting the
+:ref:`read() <func-read>` function must also support :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>`.
+
+Drivers can implement read functionality in different ways, using a
+single or multiple buffers and discarding the oldest or newest frames
+once the internal buffers are filled.
+
+:ref:`read() <func-read>` never returns a "snapshot" of a buffer being filled.
+Using a single buffer the driver will stop capturing when the
+application starts reading the buffer until the read is finished. Thus
+only the period of the vertical blanking interval is available for
+reading, or the capture rate must fall below the nominal frame rate of
+the video standard.
+
+The behavior of :ref:`read() <func-read>` when called during the active picture
+period or the vertical blanking separating the top and bottom field
+depends on the discarding policy. A driver discarding the oldest frames
+keeps capturing into an internal buffer, continuously overwriting the
+previously, not read frame, and returns the frame being received at the
+time of the :ref:`read() <func-read>` call as soon as it is complete.
+
+A driver discarding the newest frames stops capturing until the next
+:ref:`read() <func-read>` call. The frame being received at :ref:`read() <func-read>`
+time is discarded, returning the following frame instead. Again this
+implies a reduction of the capture rate to one half or less of the
+nominal frame rate. An example of this model is the video read mode of
+the bttv driver, initiating a DMA to user memory when :ref:`read() <func-read>`
+is called and returning when the DMA finished.
+
+In the multiple buffer model drivers maintain a ring of internal
+buffers, automatically advancing to the next free buffer. This allows
+continuous capturing when the application can empty the buffers fast
+enough. Again, the behavior when the driver runs out of free buffers
+depends on the discarding policy.
+
+Applications can get and set the number of buffers used internally by
+the driver with the :ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctls. They are optional,
+however. The discarding policy is not reported and cannot be changed.
+For minimum requirements see :ref:`devices`.
+
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame. This may happen for example because
+:ref:`read() <func-read>` was interrupted by a signal. On error, -1 is
+returned, and the ``errno`` variable is set appropriately. In this case
+the next read will start at the beginning of a new frame. Possible error
+codes are:
+
+EAGAIN
+    Non-blocking I/O has been selected using O_NONBLOCK and no data was
+    immediately available for reading.
+
+EBADF
+    ``fd`` is not a valid file descriptor or is not open for reading, or
+    the process already has the maximum number of files open.
+
+EBUSY
+    The driver does not support multiple read streams and the device is
+    already in use.
+
+EFAULT
+    ``buf`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal before any data was read.
+
+EIO
+    I/O error. This indicates some hardware problem or a failure to
+    communicate with a remote device (USB camera etc.).
+
+EINVAL
+    The :ref:`read() <func-read>` function is not supported by this driver, not
+    on this device, or generally not on this type of device.

+Changes of the V4L2 API
+***********************
+
+Soon after the V4L API was added to the kernel it was criticised as too
+inflexible. In August 1998 Bill Dirks proposed a number of improvements
+and began to work on documentation, example drivers and applications.
+With the help of other volunteers this eventually became the V4L2 API,
+not just an extension but a replacement for the V4L API. However it took
+another four years and two stable kernel releases until the new API was
+finally accepted for inclusion into the kernel in its present form.
+
+
+Early Versions
+==============
+
+1998-08-20: First version.
+
+1998-08-27: The :ref:`select() <func-select>` function was introduced.
+
+1998-09-10: New video standard interface.
+
+1998-09-18: The ``VIDIOC_NONCAP`` ioctl was replaced by the otherwise
+meaningless ``O_TRUNC`` :ref:`open() <func-open>` flag, and the
+aliases ``O_NONCAP`` and ``O_NOIO`` were defined. Applications can set
+this flag if they intend to access controls only, as opposed to capture
+applications which need exclusive access. The ``VIDEO_STD_XXX``
+identifiers are now ordinals instead of flags, and the
+``video_std_construct()`` helper function takes id and
+transmission arguments.
+
+1998-09-28: Revamped video standard. Made video controls individually
+enumerable.
+
+1998-10-02: The ``id`` field was removed from struct
+struct ``video_standard`` and the color subcarrier fields were
+renamed. The :ref:`VIDIOC_QUERYSTD` ioctl was
+renamed to :ref:`VIDIOC_ENUMSTD`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` to
+:ref:`VIDIOC_ENUMINPUT`. A first draft of the
+Codec API was released.
+
+1998-11-08: Many minor changes. Most symbols have been renamed. Some
+material changes to struct :c:type:`v4l2_capability`.
+
+1998-11-12: The read/write directon of some ioctls was misdefined.
+
+1998-11-14: ``V4L2_PIX_FMT_RGB24`` changed to ``V4L2_PIX_FMT_BGR24``,
+and ``V4L2_PIX_FMT_RGB32`` changed to ``V4L2_PIX_FMT_BGR32``. Audio
+controls are now accessible with the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls under names starting
+with ``V4L2_CID_AUDIO``. The ``V4L2_MAJOR`` define was removed from
+``videodev.h`` since it was only used once in the ``videodev`` kernel
+module. The ``YUV422`` and ``YUV411`` planar image formats were added.
+
+1998-11-28: A few ioctl symbols changed. Interfaces for codecs and video
+output devices were added.
+
+1999-01-14: A raw VBI capture interface was added.
+
+1999-01-19: The ``VIDIOC_NEXTBUF`` ioctl was removed.
+
+
+V4L2 Version 0.16 1999-01-31
+============================
+
+1999-01-27: There is now one QBUF ioctl, VIDIOC_QWBUF and VIDIOC_QRBUF
+are gone. VIDIOC_QBUF takes a v4l2_buffer as a parameter. Added
+digital zoom (cropping) controls.
+
+
+V4L2 Version 0.18 1999-03-16
+============================
+
+Added a v4l to V4L2 ioctl compatibility layer to videodev.c. Driver
+writers, this changes how you implement your ioctl handler. See the
+Driver Writer's Guide. Added some more control id codes.
+
+
+V4L2 Version 0.19 1999-06-05
+============================
+
+1999-03-18: Fill in the category and catname fields of v4l2_queryctrl
+objects before passing them to the driver. Required a minor change to
+the VIDIOC_QUERYCTRL handlers in the sample drivers.
+
+1999-03-31: Better compatibility for v4l memory capture ioctls. Requires
+changes to drivers to fully support new compatibility features, see
+Driver Writer's Guide and v4l2cap.c. Added new control IDs:
+V4L2_CID_HFLIP, _VFLIP. Changed V4L2_PIX_FMT_YUV422P to _YUV422P,
+and _YUV411P to _YUV411P.
+
+1999-04-04: Added a few more control IDs.
+
+1999-04-07: Added the button control type.
+
+1999-05-02: Fixed a typo in videodev.h, and added the
+V4L2_CTRL_FLAG_GRAYED (later V4L2_CTRL_FLAG_GRABBED) flag.
+
+1999-05-20: Definition of VIDIOC_G_CTRL was wrong causing a
+malfunction of this ioctl.
+
+1999-06-05: Changed the value of V4L2_CID_WHITENESS.
+
+
+V4L2 Version 0.20 (1999-09-10)
+==============================
+
+Version 0.20 introduced a number of changes which were *not backward
+compatible* with 0.19 and earlier versions. Purpose of these changes was
+to simplify the API, while making it more extensible and following
+common Linux driver API conventions.
+
+1. Some typos in ``V4L2_FMT_FLAG`` symbols were fixed. struct
+   :c:type:`v4l2_clip` was changed for compatibility with
+   v4l. (1999-08-30)
+
+2. ``V4L2_TUNER_SUB_LANG1`` was added. (1999-09-05)
+
+3. All ioctl() commands that used an integer argument now take a pointer
+   to an integer. Where it makes sense, ioctls will return the actual
+   new value in the integer pointed to by the argument, a common
+   convention in the V4L2 API. The affected ioctls are: VIDIOC_PREVIEW,
+   VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_S_FREQ,
+   VIDIOC_S_INPUT, VIDIOC_S_OUTPUT, VIDIOC_S_EFFECT. For example
+
+
+   .. code-block:: c
+
+       err = ioctl (fd, VIDIOC_XXX, V4L2_XXX);
+
+   becomes
+
+
+   .. code-block:: c
+
+       int a = V4L2_XXX; err = ioctl(fd, VIDIOC_XXX, &a);
+
+4. All the different get- and set-format commands were swept into one
+   :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+   :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl taking a union and a
+   type field selecting the union member as parameter. Purpose is to
+   simplify the API by eliminating several ioctls and to allow new and
+   driver private data streams without adding new ioctls.
+
+   This change obsoletes the following ioctls: ``VIDIOC_S_INFMT``,
+   ``VIDIOC_G_INFMT``, ``VIDIOC_S_OUTFMT``, ``VIDIOC_G_OUTFMT``,
+   ``VIDIOC_S_VBIFMT`` and ``VIDIOC_G_VBIFMT``. The image format
+   structure struct :c:type:`v4l2_format` was renamed to struct
+   :c:type:`v4l2_pix_format`, while struct
+   :c:type:`v4l2_format` is now the envelopping structure
+   for all format negotiations.
+
+5. Similar to the changes above, the ``VIDIOC_G_PARM`` and
+   ``VIDIOC_S_PARM`` ioctls were merged with ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM``. A ``type`` field in the new struct
+   :c:type:`v4l2_streamparm` selects the respective
+   union member.
+
+   This change obsoletes the ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM`` ioctls.
+
+6. Control enumeration was simplified, and two new control flags were
+   introduced and one dropped. The ``catname`` field was replaced by a
+   ``group`` field.
+
+   Drivers can now flag unsupported and temporarily unavailable controls
+   with ``V4L2_CTRL_FLAG_DISABLED`` and ``V4L2_CTRL_FLAG_GRABBED``
+   respectively. The ``group`` name indicates a possibly narrower
+   classification than the ``category``. In other words, there may be
+   multiple groups within a category. Controls within a group would
+   typically be drawn within a group box. Controls in different
+   categories might have a greater separation, or may even appear in
+   separate windows.
+
+7. The struct :c:type:`v4l2_buffer` ``timestamp`` was
+   changed to a 64 bit integer, containing the sampling or output time
+   of the frame in nanoseconds. Additionally timestamps will be in
+   absolute system time, not starting from zero at the beginning of a
+   stream. The data type name for timestamps is stamp_t, defined as a
+   signed 64-bit integer. Output devices should not send a buffer out
+   until the time in the timestamp field has arrived. I would like to
+   follow SGI's lead, and adopt a multimedia timestamping system like
+   their UST (Unadjusted System Time). See
+   http://web.archive.org/web/\*/http://reality.sgi.com
+   /cpirazzi_engr/lg/time/intro.html. UST uses timestamps that are
+   64-bit signed integers (not struct timeval's) and given in nanosecond
+   units. The UST clock starts at zero when the system is booted and
+   runs continuously and uniformly. It takes a little over 292 years for
+   UST to overflow. There is no way to set the UST clock. The regular
+   Linux time-of-day clock can be changed periodically, which would
+   cause errors if it were being used for timestamping a multimedia
+   stream. A real UST style clock will require some support in the
+   kernel that is not there yet. But in anticipation, I will change the
+   timestamp field to a 64-bit integer, and I will change the
+   v4l2_masterclock_gettime() function (used only by drivers) to
+   return a 64-bit integer.
+
+8. A ``sequence`` field was added to struct
+   :c:type:`v4l2_buffer`. The ``sequence`` field counts
+   captured frames, it is ignored by output devices. When a capture
+   driver drops a frame, the sequence number of that frame is skipped.
+
+
+V4L2 Version 0.20 incremental changes
+=====================================
+
+1999-12-23: In struct :c:type:`v4l2_vbi_format` the
+``reserved1`` field became ``offset``. Previously drivers were required
+to clear the ``reserved1`` field.
+
+2000-01-13: The ``V4L2_FMT_FLAG_NOT_INTERLACED`` flag was added.
+
+2000-07-31: The ``linux/poll.h`` header is now included by
+``videodev.h`` for compatibility with the original ``videodev.h`` file.
+
+2000-11-20: ``V4L2_TYPE_VBI_OUTPUT`` and ``V4L2_PIX_FMT_Y41P`` were
+added.
+
+2000-11-25: ``V4L2_TYPE_VBI_INPUT`` was added.
+
+2000-12-04: A couple typos in symbol names were fixed.
+
+2001-01-18: To avoid namespace conflicts the ``fourcc`` macro defined in
+the ``videodev.h`` header file was renamed to ``v4l2_fourcc``.
+
+2001-01-25: A possible driver-level compatibility problem between the
+``videodev.h`` file in Linux 2.4.0 and the ``videodev.h`` file included
+in the ``videodevX`` patch was fixed. Users of an earlier version of
+``videodevX`` on Linux 2.4.0 should recompile their V4L and V4L2
+drivers.
+
+2001-01-26: A possible kernel-level incompatibility between the
+``videodev.h`` file in the ``videodevX`` patch and the ``videodev.h``
+file in Linux 2.2.x with devfs patches applied was fixed.
+
+2001-03-02: Certain V4L ioctls which pass data in both direction
+although they are defined with read-only parameter, did not work
+correctly through the backward compatibility layer. [Solution?]
+
+2001-04-13: Big endian 16-bit RGB formats were added.
+
+2001-09-17: New YUV formats and the
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctls were added.
+(The old ``VIDIOC_G_FREQ`` and ``VIDIOC_S_FREQ`` ioctls did not take
+multiple tuners into account.)
+
+2000-09-18: ``V4L2_BUF_TYPE_VBI`` was added. This may *break
+compatibility* as the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls may fail now if the struct
+struct ``v4l2_fmt`` ``type`` field does not contain
+``V4L2_BUF_TYPE_VBI``. In the documentation of the struct
+:c:type:`v4l2_vbi_format` ``offset`` field the
+ambiguous phrase "rising edge" was changed to "leading edge".
+
+
+V4L2 Version 0.20 2000-11-23
+============================
+
+A number of changes were made to the raw VBI interface.
+
+1. Figures clarifying the line numbering scheme were added to the V4L2
+   API specification. The ``start``\ [0] and ``start``\ [1] fields no
+   longer count line numbers beginning at zero. Rationale: a) The
+   previous definition was unclear. b) The ``start``\ [] values are
+   ordinal numbers. c) There is no point in inventing a new line
+   numbering scheme. We now use line number as defined by ITU-R, period.
+   Compatibility: Add one to the start values. Applications depending on
+   the previous semantics may not function correctly.
+
+2. The restriction "count[0] > 0 and count[1] > 0" has been relaxed to
+   "(count[0] + count[1]) > 0". Rationale: Drivers may allocate
+   resources at scan line granularity and some data services are
+   transmitted only on the first field. The comment that both ``count``
+   values will usually be equal is misleading and pointless and has been
+   removed. This change *breaks compatibility* with earlier versions:
+   Drivers may return ``EINVAL``, applications may not function correctly.
+
+3. Drivers are again permitted to return negative (unknown) start values
+   as proposed earlier. Why this feature was dropped is unclear. This
+   change may *break compatibility* with applications depending on the
+   start values being positive. The use of ``EBUSY`` and ``EINVAL``
+   error codes with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl was
+   clarified. The ``EBUSY`` error code was finally documented, and the
+   ``reserved2`` field which was previously mentioned only in the
+   ``videodev.h`` header file.
+
+4. New buffer types ``V4L2_TYPE_VBI_INPUT`` and ``V4L2_TYPE_VBI_OUTPUT``
+   were added. The former is an alias for the old ``V4L2_TYPE_VBI``, the
+   latter was missing in the ``videodev.h`` file.
+
+
+V4L2 Version 0.20 2002-07-25
+============================
+
+Added sliced VBI interface proposal.
+
+
+V4L2 in Linux 2.5.46, 2002-10
+=============================
+
+Around October-November 2002, prior to an announced feature freeze of
+Linux 2.5, the API was revised, drawing from experience with V4L2 0.20.
+This unnamed version was finally merged into Linux 2.5.46.
+
+1.  As specified in :ref:`related`, drivers must make related device
+    functions available under all minor device numbers.
+
+2.  The :ref:`open() <func-open>` function requires access mode
+    ``O_RDWR`` regardless of the device type. All V4L2 drivers
+    exchanging data with applications must support the ``O_NONBLOCK``
+    flag. The ``O_NOIO`` flag, a V4L2 symbol which aliased the
+    meaningless ``O_TRUNC`` to indicate accesses without data exchange
+    (panel applications) was dropped. Drivers must stay in "panel mode"
+    until the application attempts to initiate a data exchange, see
+    :ref:`open`.
+
+3.  The struct :c:type:`v4l2_capability` changed
+    dramatically. Note that also the size of the structure changed,
+    which is encoded in the ioctl request code, thus older V4L2 devices
+    will respond with an ``EINVAL`` error code to the new
+    :ref:`VIDIOC_QUERYCAP` ioctl.
+
+    There are new fields to identify the driver, a new RDS device
+    function ``V4L2_CAP_RDS_CAPTURE``, the ``V4L2_CAP_AUDIO`` flag
+    indicates if the device has any audio connectors, another I/O
+    capability ``V4L2_CAP_ASYNCIO`` can be flagged. In response to these
+    changes the ``type`` field became a bit set and was merged into the
+    ``flags`` field. ``V4L2_FLAG_TUNER`` was renamed to
+    ``V4L2_CAP_TUNER``, ``V4L2_CAP_VIDEO_OVERLAY`` replaced
+    ``V4L2_FLAG_PREVIEW`` and ``V4L2_CAP_VBI_CAPTURE`` and
+    ``V4L2_CAP_VBI_OUTPUT`` replaced ``V4L2_FLAG_DATA_SERVICE``.
+    ``V4L2_FLAG_READ`` and ``V4L2_FLAG_WRITE`` were merged into
+    ``V4L2_CAP_READWRITE``.
+
+    The redundant fields ``inputs``, ``outputs`` and ``audios`` were
+    removed. These properties can be determined as described in
+    :ref:`video` and :ref:`audio`.
+
+    The somewhat volatile and therefore barely useful fields
+    ``maxwidth``, ``maxheight``, ``minwidth``, ``minheight``,
+    ``maxframerate`` were removed. This information is available as
+    described in :ref:`format` and :ref:`standard`.
+
+    ``V4L2_FLAG_SELECT`` was removed. We believe the select() function
+    is important enough to require support of it in all V4L2 drivers
+    exchanging data with applications. The redundant
+    ``V4L2_FLAG_MONOCHROME`` flag was removed, this information is
+    available as described in :ref:`format`.
+
+4.  In struct :c:type:`v4l2_input` the ``assoc_audio``
+    field and the ``capability`` field and its only flag
+    ``V4L2_INPUT_CAP_AUDIO`` was replaced by the new ``audioset`` field.
+    Instead of linking one video input to one audio input this field
+    reports all audio inputs this video input combines with.
+
+    New fields are ``tuner`` (reversing the former link from tuners to
+    video inputs), ``std`` and ``status``.
+
+    Accordingly struct :c:type:`v4l2_output` lost its
+    ``capability`` and ``assoc_audio`` fields. ``audioset``,
+    ``modulator`` and ``std`` where added instead.
+
+5.  The struct :c:type:`v4l2_audio` field ``audio`` was
+    renamed to ``index``, for consistency with other structures. A new
+    capability flag ``V4L2_AUDCAP_STEREO`` was added to indicated if the
+    audio input in question supports stereo sound.
+    ``V4L2_AUDCAP_EFFECTS`` and the corresponding ``V4L2_AUDMODE`` flags
+    where removed. This can be easily implemented using controls.
+    (However the same applies to AVL which is still there.)
+
+    Again for consistency the struct
+    :c:type:`v4l2_audioout` field ``audio`` was renamed
+    to ``index``.
+
+6.  The struct :c:type:`v4l2_tuner` ``input`` field was
+    replaced by an ``index`` field, permitting devices with multiple
+    tuners. The link between video inputs and tuners is now reversed,
+    inputs point to their tuner. The ``std`` substructure became a
+    simple set (more about this below) and moved into struct
+    :c:type:`v4l2_input`. A ``type`` field was added.
+
+    Accordingly in struct :c:type:`v4l2_modulator` the
+    ``output`` was replaced by an ``index`` field.
+
+    In struct :c:type:`v4l2_frequency` the ``port``
+    field was replaced by a ``tuner`` field containing the respective
+    tuner or modulator index number. A tuner ``type`` field was added
+    and the ``reserved`` field became larger for future extensions
+    (satellite tuners in particular).
+
+7.  The idea of completely transparent video standards was dropped.
+    Experience showed that applications must be able to work with video
+    standards beyond presenting the user a menu. Instead of enumerating
+    supported standards with an ioctl applications can now refer to
+    standards by :ref:`v4l2_std_id <v4l2-std-id>` and symbols
+    defined in the ``videodev2.h`` header file. For details see
+    :ref:`standard`. The :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+    :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` now take a pointer to this
+    type as argument. :ref:`VIDIOC_QUERYSTD` was
+    added to autodetect the received standard, if the hardware has this
+    capability. In struct :c:type:`v4l2_standard` an
+    ``index`` field was added for
+    :ref:`VIDIOC_ENUMSTD`. A
+    :ref:`v4l2_std_id <v4l2-std-id>` field named ``id`` was added as
+    machine readable identifier, also replacing the ``transmission``
+    field. The misleading ``framerate`` field was renamed to
+    ``frameperiod``. The now obsolete ``colorstandard`` information,
+    originally needed to distguish between variations of standards, were
+    removed.
+
+    Struct ``v4l2_enumstd`` ceased to be.
+    :ref:`VIDIOC_ENUMSTD` now takes a pointer to a
+    struct :c:type:`v4l2_standard` directly. The
+    information which standards are supported by a particular video
+    input or output moved into struct :c:type:`v4l2_input`
+    and struct :c:type:`v4l2_output` fields named ``std``,
+    respectively.
+
+8.  The struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` fields
+    ``category`` and ``group`` did not catch on and/or were not
+    implemented as expected and therefore removed.
+
+9.  The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl was added to
+    negotiate data formats as with
+    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, but without the overhead of
+    programming the hardware and regardless of I/O in progress.
+
+    In struct :c:type:`v4l2_format` the ``fmt`` union was
+    extended to contain struct :c:type:`v4l2_window`. All
+    image format negotiations are now possible with ``VIDIOC_G_FMT``,
+    ``VIDIOC_S_FMT`` and ``VIDIOC_TRY_FMT``; ioctl. The ``VIDIOC_G_WIN``
+    and ``VIDIOC_S_WIN`` ioctls to prepare for a video overlay were
+    removed. The ``type`` field changed to type enum
+    :c:type:`v4l2_buf_type` and the buffer type names
+    changed as follows.
+
+
+
+    .. flat-table::

+	:stub-columns: 0

+	  - ``V4L2_BUF_TYPE_PRIVATE`` (but this is deprecated)
+
+
+10. In struct :c:type:`v4l2_fmtdesc` a enum
+    :c:type:`v4l2_buf_type` field named ``type`` was
+    added as in struct :c:type:`v4l2_format`. The
+    ``VIDIOC_ENUM_FBUFFMT`` ioctl is no longer needed and was removed.
+    These calls can be replaced by
+    :ref:`VIDIOC_ENUM_FMT` with type
+    ``V4L2_BUF_TYPE_VIDEO_OVERLAY``.
+
+11. In struct :c:type:`v4l2_pix_format` the ``depth``
+    field was removed, assuming applications which recognize the format
+    by its four-character-code already know the color depth, and others
+    do not care about it. The same rationale lead to the removal of the
+    ``V4L2_FMT_FLAG_COMPRESSED`` flag. The
+    ``V4L2_FMT_FLAG_SWCONVECOMPRESSED`` flag was removed because drivers
+    are not supposed to convert images in kernel space. A user library
+    of conversion functions should be provided instead. The
+    ``V4L2_FMT_FLAG_BYTESPERLINE`` flag was redundant. Applications can
+    set the ``bytesperline`` field to zero to get a reasonable default.
+    Since the remaining flags were replaced as well, the ``flags`` field
+    itself was removed.
+
+    The interlace flags were replaced by a enum
+    :c:type:`v4l2_field` value in a newly added ``field``
+    field.
+
+
+
+    .. flat-table::
+	:header-rows:  1
+	:stub-columns: 0
+
+	* - Old flag
+	  - enum :c:type:`v4l2_field`
+	* - ``V4L2_FMT_FLAG_NOT_INTERLACED``
+	  - ?

+	* - ``-``
+	  - ``V4L2_FIELD_SEQ_BT``
+	* - ``-``
+	  - ``V4L2_FIELD_ALTERNATE``
+
+
+    The color space flags were replaced by a enum
+    :c:type:`v4l2_colorspace` value in a newly added
+    ``colorspace`` field, where one of ``V4L2_COLORSPACE_SMPTE170M``,
+    ``V4L2_COLORSPACE_BT878``, ``V4L2_COLORSPACE_470_SYSTEM_M`` or
+    ``V4L2_COLORSPACE_470_SYSTEM_BG`` replaces ``V4L2_FMT_CS_601YUV``.
+
+12. In struct :c:type:`v4l2_requestbuffers` the
+    ``type`` field was properly defined as enum
+    :c:type:`v4l2_buf_type`. Buffer types changed as
+    mentioned above. A new ``memory`` field of type enum
+    :c:type:`v4l2_memory` was added to distinguish between
+    I/O methods using buffers allocated by the driver or the
+    application. See :ref:`io` for details.
+
+13. In struct :c:type:`v4l2_buffer` the ``type`` field was
+    properly defined as enum :c:type:`v4l2_buf_type`.
+    Buffer types changed as mentioned above. A ``field`` field of type
+    enum :c:type:`v4l2_field` was added to indicate if a
+    buffer contains a top or bottom field. The old field flags were
+    removed. Since no unadjusted system time clock was added to the
+    kernel as planned, the ``timestamp`` field changed back from type
+    stamp_t, an unsigned 64 bit integer expressing the sample time in
+    nanoseconds, to struct :c:type:`timeval`. With the addition
+    of a second memory mapping method the ``offset`` field moved into
+    union ``m``, and a new ``memory`` field of type enum
+    :c:type:`v4l2_memory` was added to distinguish between
+    I/O methods. See :ref:`io` for details.
+
+    The ``V4L2_BUF_REQ_CONTIG`` flag was used by the V4L compatibility
+    layer, after changes to this code it was no longer needed. The
+    ``V4L2_BUF_ATTR_DEVICEMEM`` flag would indicate if the buffer was
+    indeed allocated in device memory rather than DMA-able system
+    memory. It was barely useful and so was removed.
+
+14. In struct :c:type:`v4l2_framebuffer` the
+    ``base[3]`` array anticipating double- and triple-buffering in
+    off-screen video memory, however without defining a synchronization
+    mechanism, was replaced by a single pointer. The
+    ``V4L2_FBUF_CAP_SCALEUP`` and ``V4L2_FBUF_CAP_SCALEDOWN`` flags were
+    removed. Applications can determine this capability more accurately
+    using the new cropping and scaling interface. The
+    ``V4L2_FBUF_CAP_CLIPPING`` flag was replaced by
+    ``V4L2_FBUF_CAP_LIST_CLIPPING`` and
+    ``V4L2_FBUF_CAP_BITMAP_CLIPPING``.
+
+15. In struct :c:type:`v4l2_clip` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``c`` substructure of
+    type struct :c:type:`v4l2_rect`. The ``x`` and ``y``
+    fields were renamed to ``left`` and ``top``, i. e. offsets to a
+    context dependent origin.
+
+16. In struct :c:type:`v4l2_window` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``w`` substructure as
+    above. A ``field`` field of type :c:type:`v4l2_field` was added to
+    distinguish between field and frame (interlaced) overlay.
+
+17. The digital zoom interface, including struct
+    struct ``v4l2_zoomcap``, struct
+    struct ``v4l2_zoom``, ``V4L2_ZOOM_NONCAP`` and
+    ``V4L2_ZOOM_WHILESTREAMING`` was replaced by a new cropping and
+    scaling interface. The previously unused struct
+    struct :c:type:`v4l2_cropcap` and struct :c:type:`v4l2_crop`
+    where redefined for this purpose. See :ref:`crop` for details.
+
+18. In struct :c:type:`v4l2_vbi_format` the
+    ``SAMPLE_FORMAT`` field now contains a four-character-code as used
+    to identify video image formats and ``V4L2_PIX_FMT_GREY`` replaces
+    the ``V4L2_VBI_SF_UBYTE`` define. The ``reserved`` field was
+    extended.
+
+19. In struct :c:type:`v4l2_captureparm` the type of
+    the ``timeperframe`` field changed from unsigned long to struct
+    :c:type:`v4l2_fract`. This allows the accurate
+    expression of multiples of the NTSC-M frame rate 30000 / 1001. A new
+    field ``readbuffers`` was added to control the driver behaviour in
+    read I/O mode.
+
+    Similar changes were made to struct
+    :c:type:`v4l2_outputparm`.
+
+20. The struct ``v4l2_performance`` and
+    ``VIDIOC_G_PERF`` ioctl were dropped. Except when using the
+    :ref:`read/write I/O method <rw>`, which is limited anyway, this
+    information is already available to applications.
+
+21. The example transformation from RGB to YCbCr color space in the old
+    V4L2 documentation was inaccurate, this has been corrected in
+    :ref:`pixfmt`.
+
+
+V4L2 2003-06-19
+===============
+
+1. A new capability flag ``V4L2_CAP_RADIO`` was added for radio devices.
+   Prior to this change radio devices would identify solely by having
+   exactly one tuner whose type field reads ``V4L2_TUNER_RADIO``.
+
+2. An optional driver access priority mechanism was added, see
+   :ref:`app-pri` for details.
+
+3. The audio input and output interface was found to be incomplete.
+
+   Previously the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl would
+   enumerate the available audio inputs. An ioctl to determine the
+   current audio input, if more than one combines with the current video
+   input, did not exist. So ``VIDIOC_G_AUDIO`` was renamed to
+   ``VIDIOC_G_AUDIO_OLD``, this ioctl was removed on Kernel 2.6.39. The
+   :ref:`VIDIOC_ENUMAUDIO` ioctl was added to
+   enumerate audio inputs, while
+   :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` now reports the current
+   audio input.
+
+   The same changes were made to
+   :ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>`.
+
+   Until further the "videodev" module will automatically translate
+   between the old and new ioctls, but drivers and applications must be
+   updated to successfully compile again.
+
+4. The :ref:`VIDIOC_OVERLAY` ioctl was incorrectly
+   defined with write-read parameter. It was changed to write-only,
+   while the write-read version was renamed to ``VIDIOC_OVERLAY_OLD``.
+   The old ioctl was removed on Kernel 2.6.39. Until further the
+   "videodev" kernel module will automatically translate to the new
+   version, so drivers must be recompiled, but not applications.
+
+5. :ref:`overlay` incorrectly stated that clipping rectangles define
+   regions where the video can be seen. Correct is that clipping
+   rectangles define regions where *no* video shall be displayed and so
+   the graphics surface can be seen.
+
+6. The :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` and
+   :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls were defined with
+   write-only parameter, inconsistent with other ioctls modifying their
+   argument. They were changed to write-read, while a ``_OLD`` suffix
+   was added to the write-only versions. The old ioctls were removed on
+   Kernel 2.6.39. Drivers and applications assuming a constant parameter
+   need an update.
+
+
+V4L2 2003-11-05
+===============
+
+1. In :ref:`pixfmt-rgb` the following pixel formats were incorrectly
+   transferred from Bill Dirks' V4L2 specification. Descriptions below
+   refer to bytes in memory, in ascending address order.
+
+
+
+   .. flat-table::
+       :header-rows:  1

+
+
+   The ``V4L2_PIX_FMT_BGR24`` example was always correct.
+
+   In :ref:`v4l-image-properties` the mapping of the V4L
+   ``VIDEO_PALETTE_RGB24`` and ``VIDEO_PALETTE_RGB32`` formats to V4L2
+   pixel formats was accordingly corrected.
+
+2. Unrelated to the fixes above, drivers may still interpret some V4L2
+   RGB pixel formats differently. These issues have yet to be addressed,
+   for details see :ref:`pixfmt-rgb`.
+
+
+V4L2 in Linux 2.6.6, 2004-05-09
+===============================
+
+1. The :ref:`VIDIOC_CROPCAP` ioctl was incorrectly
+   defined with read-only parameter. It is now defined as write-read
+   ioctl, while the read-only version was renamed to
+   ``VIDIOC_CROPCAP_OLD``. The old ioctl was removed on Kernel 2.6.39.
+
+
+V4L2 in Linux 2.6.8
+===================
+
+1. A new field ``input`` (former ``reserved[0]``) was added to the
+   struct :c:type:`v4l2_buffer` structure. Purpose of this
+   field is to alternate between video inputs (e. g. cameras) in step
+   with the video capturing process. This function must be enabled with
+   the new ``V4L2_BUF_FLAG_INPUT`` flag. The ``flags`` field is no
+   longer read-only.
+
+
+V4L2 spec erratum 2004-08-01
+============================
+
+1. The return value of the :ref:`func-open` function was incorrectly
+   documented.
+
+2. Audio output ioctls end in -AUDOUT, not -AUDIOOUT.
+
+3. In the Current Audio Input example the ``VIDIOC_G_AUDIO`` ioctl took
+   the wrong argument.
+
+4. The documentation of the :ref:`VIDIOC_QBUF` and
+   :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctls did not mention the
+   struct :c:type:`v4l2_buffer` ``memory`` field. It was
+   also missing from examples. Also on the ``VIDIOC_DQBUF`` page the ``EIO``
+   error code was not documented.
+
+
+V4L2 in Linux 2.6.14
+====================
+
+1. A new sliced VBI interface was added. It is documented in
+   :ref:`sliced` and replaces the interface first proposed in V4L2
+   specification 0.8.
+
+
+V4L2 in Linux 2.6.15
+====================
+
+1. The :ref:`VIDIOC_LOG_STATUS` ioctl was added.
+
+2. New video standards ``V4L2_STD_NTSC_443``, ``V4L2_STD_SECAM_LC``,
+   ``V4L2_STD_SECAM_DK`` (a set of SECAM D, K and K1), and
+   ``V4L2_STD_ATSC`` (a set of ``V4L2_STD_ATSC_8_VSB`` and
+   ``V4L2_STD_ATSC_16_VSB``) were defined. Note the ``V4L2_STD_525_60``
+   set now includes ``V4L2_STD_NTSC_443``. See also
+   :ref:`v4l2-std-id`.
+
+3. The ``VIDIOC_G_COMP`` and ``VIDIOC_S_COMP`` ioctl were renamed to
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` respectively. Their
+   argument was replaced by a struct
+   ``v4l2_mpeg_compression`` pointer. (The
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls where removed
+   in Linux 2.6.25.)
+
+
+V4L2 spec erratum 2005-11-27
+============================
+
+The capture example in :ref:`capture-example` called the
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl without checking if
+cropping is supported. In the video standard selection example in
+:ref:`standard` the :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` call used
+the wrong argument type.
+
+
+V4L2 spec erratum 2006-01-10
+============================
+
+1. The ``V4L2_IN_ST_COLOR_KILL`` flag in struct
+   :c:type:`v4l2_input` not only indicates if the color
+   killer is enabled, but also if it is active. (The color killer
+   disables color decoding when it detects no color in the video signal
+   to improve the image quality.)
+
+2. :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` is a write-read ioctl, not
+   write-only as stated on its reference page. The ioctl changed in 2003
+   as noted above.
+
+
+V4L2 spec erratum 2006-02-03
+============================
+
+1. In struct :c:type:`v4l2_captureparm` and struct
+   :c:type:`v4l2_outputparm` the ``timeperframe``
+   field gives the time in seconds, not microseconds.
+
+
+V4L2 spec erratum 2006-02-04
+============================
+
+1. The ``clips`` field in struct :c:type:`v4l2_window`
+   must point to an array of struct :c:type:`v4l2_clip`, not
+   a linked list, because drivers ignore the struct
+   struct :c:type:`v4l2_clip`. ``next`` pointer.
+
+
+V4L2 in Linux 2.6.17
+====================
+
+1. New video standard macros were added: ``V4L2_STD_NTSC_M_KR`` (NTSC M
+   South Korea), and the sets ``V4L2_STD_MN``, ``V4L2_STD_B``,
+   ``V4L2_STD_GH`` and ``V4L2_STD_DK``. The ``V4L2_STD_NTSC`` and
+   ``V4L2_STD_SECAM`` sets now include ``V4L2_STD_NTSC_M_KR`` and
+   ``V4L2_STD_SECAM_LC`` respectively.
+
+2. A new ``V4L2_TUNER_MODE_LANG1_LANG2`` was defined to record both
+   languages of a bilingual program. The use of
+   ``V4L2_TUNER_MODE_STEREO`` for this purpose is deprecated now. See
+   the :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` section for details.
+
+
+V4L2 spec erratum 2006-09-23 (Draft 0.15)
+=========================================
+
+1. In various places ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` and
+   ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT`` of the sliced VBI interface were
+   not mentioned along with other buffer types.
+
+2. In :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` it was clarified that the struct
+   :c:type:`v4l2_audio` ``mode`` field is a flags field.
+
+3. :ref:`VIDIOC_QUERYCAP` did not mention the sliced VBI and radio
+   capability flags.
+
+4. In :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` it was clarified that applications
+   must initialize the tuner ``type`` field of struct
+   :c:type:`v4l2_frequency` before calling
+   :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`.
+
+5. The ``reserved`` array in struct
+   :c:type:`v4l2_requestbuffers` has 2 elements,
+   not 32.
+
+6. In :ref:`output` and :ref:`raw-vbi` the device file names
+   ``/dev/vout`` which never caught on were replaced by ``/dev/video``.
+
+7. With Linux 2.6.15 the possible range for VBI device minor numbers was
+   extended from 224-239 to 224-255. Accordingly device file names
+   ``/dev/vbi0`` to ``/dev/vbi31`` are possible now.
+
+
+V4L2 in Linux 2.6.18
+====================
+
+1. New ioctls :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+   :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+   :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` were added, a
+   flag to skip unsupported controls with
+   :ref:`VIDIOC_QUERYCTRL`, new control types
+   ``V4L2_CTRL_TYPE_INTEGER64`` and ``V4L2_CTRL_TYPE_CTRL_CLASS``
+   (:c:type:`v4l2_ctrl_type`), and new control flags
+   ``V4L2_CTRL_FLAG_READ_ONLY``, ``V4L2_CTRL_FLAG_UPDATE``,
+   ``V4L2_CTRL_FLAG_INACTIVE`` and ``V4L2_CTRL_FLAG_SLIDER``
+   (:ref:`control-flags`). See :ref:`extended-controls` for details.
+
+
+V4L2 in Linux 2.6.19
+====================
+
+1. In struct :c:type:`v4l2_sliced_vbi_cap` a
+   buffer type field was added replacing a reserved field. Note on
+   architectures where the size of enum types differs from int types the
+   size of the structure changed. The
+   :ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl
+   was redefined from being read-only to write-read. Applications must
+   initialize the type field and clear the reserved fields now. These
+   changes may *break the compatibility* with older drivers and
+   applications.
+
+2. The ioctls :ref:`VIDIOC_ENUM_FRAMESIZES`
+   and
+   :ref:`VIDIOC_ENUM_FRAMEINTERVALS`
+   were added.
+
+3. A new pixel format ``V4L2_PIX_FMT_RGB444`` (:ref:`pixfmt-rgb`) was
+   added.
+
+
+V4L2 spec erratum 2006-10-12 (Draft 0.17)
+=========================================
+
+1. ``V4L2_PIX_FMT_HM12`` (:ref:`reserved-formats`) is a YUV 4:2:0, not
+   4:2:2 format.
+
+
+V4L2 in Linux 2.6.21
+====================
+
+1. The ``videodev2.h`` header file is now dual licensed under GNU
+   General Public License version two or later, and under a 3-clause
+   BSD-style license.
+
+
+V4L2 in Linux 2.6.22
+====================
+
+1. Two new field orders ``V4L2_FIELD_INTERLACED_TB`` and
+   ``V4L2_FIELD_INTERLACED_BT`` were added. See :c:type:`v4l2_field` for
+   details.
+
+2. Three new clipping/blending methods with a global or straight or
+   inverted local alpha value were added to the video overlay interface.
+   See the description of the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+   and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls for details.
+
+   A new ``global_alpha`` field was added to
+   :c:type:`v4l2_window`, extending the structure. This
+   may *break compatibility* with applications using a struct
+   struct :c:type:`v4l2_window` directly. However the
+   :ref:`VIDIOC_G/S/TRY_FMT <VIDIOC_G_FMT>` ioctls, which take a
+   pointer to a :c:type:`v4l2_format` parent structure
+   with padding bytes at the end, are not affected.
+
+3. The format of the ``chromakey`` field in struct
+   :c:type:`v4l2_window` changed from "host order RGB32"
+   to a pixel value in the same format as the framebuffer. This may
+   *break compatibility* with existing applications. Drivers supporting
+   the "host order RGB32" format are not known.
+
+
+V4L2 in Linux 2.6.24
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_PAL8``, ``V4L2_PIX_FMT_YUV444``,
+   ``V4L2_PIX_FMT_YUV555``, ``V4L2_PIX_FMT_YUV565`` and
+   ``V4L2_PIX_FMT_YUV32`` were added.
+
+
+V4L2 in Linux 2.6.25
+====================
+
+1. The pixel formats :ref:`V4L2_PIX_FMT_Y16 <V4L2-PIX-FMT-Y16>` and
+   :ref:`V4L2_PIX_FMT_SBGGR16 <V4L2-PIX-FMT-SBGGR16>` were added.
+
+2. New :ref:`controls <control>` ``V4L2_CID_POWER_LINE_FREQUENCY``,
+   ``V4L2_CID_HUE_AUTO``, ``V4L2_CID_WHITE_BALANCE_TEMPERATURE``,
+   ``V4L2_CID_SHARPNESS`` and ``V4L2_CID_BACKLIGHT_COMPENSATION`` were
+   added. The controls ``V4L2_CID_BLACK_LEVEL``, ``V4L2_CID_WHITENESS``,
+   ``V4L2_CID_HCENTER`` and ``V4L2_CID_VCENTER`` were deprecated.
+
+3. A :ref:`Camera controls class <camera-controls>` was added, with
+   the new controls ``V4L2_CID_EXPOSURE_AUTO``,
+   ``V4L2_CID_EXPOSURE_ABSOLUTE``, ``V4L2_CID_EXPOSURE_AUTO_PRIORITY``,
+   ``V4L2_CID_PAN_RELATIVE``, ``V4L2_CID_TILT_RELATIVE``,
+   ``V4L2_CID_PAN_RESET``, ``V4L2_CID_TILT_RESET``,
+   ``V4L2_CID_PAN_ABSOLUTE``, ``V4L2_CID_TILT_ABSOLUTE``,
+   ``V4L2_CID_FOCUS_ABSOLUTE``, ``V4L2_CID_FOCUS_RELATIVE`` and
+   ``V4L2_CID_FOCUS_AUTO``.
+
+4. The ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls, which
+   were superseded by the :ref:`extended controls <extended-controls>`
+   interface in Linux 2.6.18, where finally removed from the
+   ``videodev2.h`` header file.
+
+
+V4L2 in Linux 2.6.26
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_Y16`` and ``V4L2_PIX_FMT_SBGGR16``
+   were added.
+
+2. Added user controls ``V4L2_CID_CHROMA_AGC`` and
+   ``V4L2_CID_COLOR_KILLER``.
+
+
+V4L2 in Linux 2.6.27

+
+
+.. _other:
+
+Relation of V4L2 to other Linux multimedia APIs
+===============================================
+
+
+.. _xvideo:
+
+X Video Extension
+-----------------
+
+The X Video Extension (abbreviated XVideo or just Xv) is an extension of
+the X Window system, implemented for example by the XFree86 project. Its
+scope is similar to V4L2, an API to video capture and output devices for
+X clients. Xv allows applications to display live video in a window,
+send window contents to a TV output, and capture or output still images
+in XPixmaps [#f1]_. With their implementation XFree86 makes the extension
+available across many operating systems and architectures.
+
+Because the driver is embedded into the X server Xv has a number of
+advantages over the V4L2 :ref:`video overlay interface <overlay>`. The
+driver can easily determine the overlay target, i. e. visible graphics
+memory or off-screen buffers for a destructive overlay. It can program
+the RAMDAC for a non-destructive overlay, scaling or color-keying, or
+the clipping functions of the video capture hardware, always in sync
+with drawing operations or windows moving or changing their stacking
+order.
+
+To combine the advantages of Xv and V4L a special Xv driver exists in
+XFree86 and XOrg, just programming any overlay capable Video4Linux
+device it finds. To enable it ``/etc/X11/XF86Config`` must contain these
+lines:
+
+::
+
+    Section "Module"
+	Load "v4l"
+    EndSection
+
+As of XFree86 4.2 this driver still supports only V4L ioctls, however it
+should work just fine with all V4L2 devices through the V4L2
+backward-compatibility layer. Since V4L2 permits multiple opens it is
+possible (if supported by the V4L2 driver) to capture video while an X
+client requested video overlay. Restrictions of simultaneous capturing
+and overlay are discussed in :ref:`overlay` apply.
+
+Only marginally related to V4L2, XFree86 extended Xv to support hardware
+YUV to RGB conversion and scaling for faster video playback, and added
+an interface to MPEG-2 decoding hardware. This API is useful to display
+images captured with V4L2 devices.
+
+
+Digital Video
+-------------
+
+V4L2 does not support digital terrestrial, cable or satellite broadcast.
+A separate project aiming at digital receivers exists. You can find its
+homepage at `https://linuxtv.org <https://linuxtv.org>`__. The Linux
+DVB API has no connection to the V4L2 API except that drivers for hybrid
+hardware may support both.

+############
+Input/Output
+############
+The V4L2 API defines several different methods to read from or write to
+a device. All drivers exchanging data with applications must support at
+least one of them.
+
+The classic I/O method using the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function is automatically selected after opening a
+V4L2 device. When the driver does not support this method attempts to
+read or write will fail at any time.
+
+Other methods must be negotiated. To select the streaming I/O method
+with memory mapped or user buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl. The asynchronous I/O
+method is not defined yet.
+
+Video overlay can be considered another I/O method, although the
+application does not directly receive the image data. It is selected by
+initiating video overlay with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. For more information see :ref:`overlay`.
+
+Generally exactly one I/O method, including overlay, is associated with
+each file descriptor. The only exceptions are applications not
+exchanging data with a driver ("panel applications", see :ref:`open`)
+and drivers permitting simultaneous video capturing and overlay using
+the same file descriptor, for compatibility with V4L and earlier
+versions of V4L2.
+
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_REQBUFS` would permit this to some
+degree, but for simplicity drivers need not support switching the I/O
+method (after first switching away from read/write) other than by
+closing and reopening the device.

+The following sections describe the various I/O methods in more detail.

+************
+Introduction
+************
+
+libv4l is a collection of libraries which adds a thin abstraction layer
+on top of video4linux2 devices. The purpose of this (thin) layer is to
+make it easy for application writers to support a wide variety of
+devices without having to write separate code for different devices in
+the same class.
+
+An example of using libv4l is provided by
+:ref:`v4l2grab <v4l2grab-example>`.
+
+libv4l consists of 3 different libraries:
+
+
+libv4lconvert
+=============
+
+libv4lconvert is a library that converts several different pixelformats
+found in V4L2 drivers into a few common RGB and YUY formats.
+
+It currently accepts the following V4L2 driver formats:
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_HM12 <V4L2-PIX-FMT-HM12>`,
+:ref:`V4L2_PIX_FMT_JPEG <V4L2-PIX-FMT-JPEG>`,
+:ref:`V4L2_PIX_FMT_MJPEG <V4L2-PIX-FMT-MJPEG>`,
+:ref:`V4L2_PIX_FMT_MR97310A <V4L2-PIX-FMT-MR97310A>`,
+:ref:`V4L2_PIX_FMT_OV511 <V4L2-PIX-FMT-OV511>`,
+:ref:`V4L2_PIX_FMT_OV518 <V4L2-PIX-FMT-OV518>`,
+:ref:`V4L2_PIX_FMT_PAC207 <V4L2-PIX-FMT-PAC207>`,
+:ref:`V4L2_PIX_FMT_PJPG <V4L2-PIX-FMT-PJPG>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`,
+:ref:`V4L2_PIX_FMT_SGBRG8 <V4L2-PIX-FMT-SGBRG8>`,
+:ref:`V4L2_PIX_FMT_SGRBG8 <V4L2-PIX-FMT-SGRBG8>`,
+:ref:`V4L2_PIX_FMT_SN9C10X <V4L2-PIX-FMT-SN9C10X>`,
+:ref:`V4L2_PIX_FMT_SN9C20X_I420 <V4L2-PIX-FMT-SN9C20X-I420>`,
+:ref:`V4L2_PIX_FMT_SPCA501 <V4L2-PIX-FMT-SPCA501>`,
+:ref:`V4L2_PIX_FMT_SPCA505 <V4L2-PIX-FMT-SPCA505>`,
+:ref:`V4L2_PIX_FMT_SPCA508 <V4L2-PIX-FMT-SPCA508>`,
+:ref:`V4L2_PIX_FMT_SPCA561 <V4L2-PIX-FMT-SPCA561>`,
+:ref:`V4L2_PIX_FMT_SQ905C <V4L2-PIX-FMT-SQ905C>`,
+:ref:`V4L2_PIX_FMT_SRGGB8 <V4L2-PIX-FMT-SRGGB8>`,
+:ref:`V4L2_PIX_FMT_UYVY <V4L2-PIX-FMT-UYVY>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`,
+:ref:`V4L2_PIX_FMT_YUYV <V4L2-PIX-FMT-YUYV>`,
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, and
+:ref:`V4L2_PIX_FMT_YVYU <V4L2-PIX-FMT-YVYU>`.
+
+Later on libv4lconvert was expanded to also be able to do various video
+processing functions to improve webcam video quality. The video
+processing is split in to 2 parts: libv4lconvert/control and
+libv4lconvert/processing.
+
+The control part is used to offer video controls which can be used to
+control the video processing functions made available by
+libv4lconvert/processing. These controls are stored application wide
+(until reboot) by using a persistent shared memory object.
+
+libv4lconvert/processing offers the actual video processing
+functionality.
+
+
+libv4l1
+=======
+
+This library offers functions that can be used to quickly make v4l1
+applications work with v4l2 devices. These functions work exactly like
+the normal open/close/etc, except that libv4l1 does full emulation of
+the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it will
+just pass calls through.
+
+Since those functions are emulations of the old V4L1 API, it shouldn't
+be used for new applications.
+
+
+libv4l2
+=======
+
+This library should be used for all modern V4L2 applications.
+
+It provides handles to call V4L2 open/ioctl/close/poll methods. Instead
+of just providing the raw output of the device, it enhances the calls in
+the sense that it will use libv4lconvert to provide more video formats
+and to enhance the image quality.
+
+In most cases, libv4l2 just passes the calls directly through to the
+v4l2 driver, intercepting the calls to
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_ENUM_FRAMESIZES <VIDIOC_ENUM_FRAMESIZES>` and
+:ref:`VIDIOC_ENUM_FRAMEINTERVALS <VIDIOC_ENUM_FRAMEINTERVALS>` in
+order to emulate the formats
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`, and
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, if they aren't
+available in the driver. :ref:`VIDIOC_ENUM_FMT <VIDIOC_ENUM_FMT>`
+keeps enumerating the hardware supported formats, plus the emulated
+formats offered by libv4l at the end.
+
+
+.. _libv4l-ops:
+
+Libv4l device control functions
+-------------------------------
+
+The common file operation methods are provided by libv4l.
+
+Those functions operate just like the gcc function ``dup()`` and
+V4L2 functions
+:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
+:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`read() <v4l2-read>`,
+:c:func:`mmap() <v4l2-mmap>` and :c:func:`munmap() <v4l2-munmap>`:
+
+.. c:function:: int v4l2_open(const char *file, int oflag, ...)
+
+   operates like the :c:func:`open() <v4l2-open>` function.
+
+.. c:function:: int v4l2_close(int fd)
+
+   operates like the :c:func:`close() <v4l2-close>` function.
+
+.. c:function:: int v4l2_dup(int fd)
+
+   operates like the libc ``dup()`` function, duplicating a file handler.
+
+.. c:function:: int v4l2_ioctl (int fd, unsigned long int request, ...)
+
+   operates like the :c:func:`ioctl() <v4l2-ioctl>` function.
+
+.. c:function:: int v4l2_read (int fd, void* buffer, size_t n)
+
+   operates like the :c:func:`read() <v4l2-read>` function.
+
+.. c:function:: void v4l2_mmap(void *start, size_t length, int prot, int flags, int fd, int64_t offset);
+
+   operates like the :c:func:`munmap() <v4l2-munmap>` function.
+
+.. c:function:: int v4l2_munmap(void *_start, size_t length);
+
+   operates like the :c:func:`munmap() <v4l2-munmap>` function.
+
+Those functions provide additional control:
+
+.. c:function:: int v4l2_fd_open(int fd, int v4l2_flags)
+
+   opens an already opened fd for further use through v4l2lib and possibly
+   modify libv4l2's default behavior through the ``v4l2_flags`` argument.
+   Currently, ``v4l2_flags`` can be ``V4L2_DISABLE_CONVERSION``, to disable
+   format conversion.
+
+.. c:function:: int v4l2_set_control(int fd, int cid, int value)
+
+   This function takes a value of 0 - 65535, and then scales that range to the

+   not locked sets the cid to the scaled value.
+
+.. c:function:: int v4l2_get_control(int fd, int cid)
+
+   This function returns a value of 0 - 65535, scaled to from the actual range
+   of the given v4l control id. when the cid does not exist, could not be
+   accessed for some reason, or some error occurred 0 is returned.
+
+
+v4l1compat.so wrapper library
+=============================
+
+This library intercepts calls to
+:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
+:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`mmap() <v4l2-mmap>` and
+:c:func:`munmap() <v4l2-munmap>`
+operations and redirects them to the libv4l counterparts, by using
+``LD_PRELOAD=/usr/lib/v4l1compat.so``. It also emulates V4L1 calls via V4L2
+API.
+
+It allows usage of binary legacy applications that still don't use
+libv4l.

+******************************
+Streaming I/O (Memory Mapping)
+******************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. There are two
+streaming methods, to determine if the memory mapping flavor is
+supported applications must call the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_MMAP``.
+
+Streaming is an I/O method where only pointers to buffers are exchanged
+between application and driver, the data itself is not copied. Memory
+mapping is primarily intended to map buffers in device memory into the
+application's address space. Device memory can be for example the video
+memory on a graphics card with a video capture add-on. However, being
+the most efficient I/O method available for a long time, many other
+drivers support streaming as well, allocating buffers in DMA-able main
+memory.
+
+A driver can support many sets of buffers. Each set is identified by a
+unique buffer type value. The sets are independent and each set can hold
+a different type of data. To access different sets at the same time
+different file descriptors must be used. [#f1]_
+
+To allocate device buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl with the desired number
+of buffers and buffer type, for example ``V4L2_BUF_TYPE_VIDEO_CAPTURE``.
+This ioctl can also be used to change the number of buffers or to free
+the allocated memory, provided none of the buffers are still mapped.
+
+Before applications can access the buffers they must map them into their
+address space with the :ref:`mmap() <func-mmap>` function. The
+location of the buffers in device memory can be determined with the
+:ref:`VIDIOC_QUERYBUF` ioctl. In the single-planar
+API case, the ``m.offset`` and ``length`` returned in a struct
+:c:type:`v4l2_buffer` are passed as sixth and second
+parameter to the :ref:`mmap() <func-mmap>` function. When using the
+multi-planar API, struct :c:type:`v4l2_buffer` contains an
+array of struct :c:type:`v4l2_plane` structures, each
+containing its own ``m.offset`` and ``length``. When using the
+multi-planar API, every plane of every buffer has to be mapped
+separately, so the number of calls to :ref:`mmap() <func-mmap>` should
+be equal to number of buffers times number of planes in each buffer. The
+offset and length values must not be modified. Remember, the buffers are
+allocated in physical memory, as opposed to virtual memory, which can be
+swapped out to disk. Applications should free the buffers as soon as
+possible with the :ref:`munmap() <func-munmap>` function.
+

+
+Conceptually streaming drivers maintain two buffer queues, an incoming
+and an outgoing queue. They separate the synchronous capture or output
+operation locked to a video clock from the application which is subject
+to random disk or network delays and preemption by other processes,
+thereby reducing the probability of data loss. The queues are organized
+as FIFOs, buffers will be output in the order enqueued in the incoming
+FIFO, and were captured in the order dequeued from the outgoing FIFO.
+
+The driver may require a minimum number of buffers enqueued at all times
+to function, apart of this no limit exists on the number of buffers
+applications can enqueue in advance, or dequeue and process. They can
+also enqueue in a different order than buffers have been dequeued, and
+the driver can *fill* enqueued *empty* buffers in any order.  [#f2]_ The
+index number of a buffer (struct :c:type:`v4l2_buffer`
+``index``) plays no role here, it only identifies the buffer.
+
+Initially all mapped buffers are in dequeued state, inaccessible by the
+driver. For capturing applications it is customary to first enqueue all
+mapped buffers, then to start capturing and enter the read loop. Here
+the application waits until a filled buffer can be dequeued, and
+re-enqueues the buffer when the data is no longer needed. Output
+applications fill and enqueue buffers, when enough buffers are stacked
+up the output is started with :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`.
+In the write loop, when the application runs out of free buffers, it
+must wait until an empty buffer can be dequeued and reused.
+
+To enqueue and dequeue a buffer applications use the
+:ref:`VIVIOC_QBUF <VIDIOC_QBUF>` and :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+ioctl. The status of a buffer being mapped, enqueued, full or empty can
+be determined at any time using the :ref:`VIDIOC_QUERYBUF` ioctl. Two
+methods exist to suspend execution of the application until one or more
+buffers can be dequeued.  By default :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+blocks when no buffer is in the outgoing queue. When the ``O_NONBLOCK``
+flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The :ref:`select() <func-select>`
+or :ref:`poll() <func-poll>` functions are always available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF
+<VIDIOC_STREAMON>` ioctl.
+
+.. note:::ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+   removes all buffers from both queues as a side effect. Since there is
+   no notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct ::c:type:`v4l2_buffer` ``timestamp`` of captured
+   or outputted buffers.
+
+Drivers implementing memory mapping I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QUERYBUF
+<VIDIOC_QUERYBUF>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the :ref:`mmap()
+<func-mmap>`, :ref:`munmap() <func-munmap>`, :ref:`select()
+<func-select>` and :ref:`poll() <func-poll>` function. [#f3]_
+
+[capture example]
+
+.. [#f1]
+   One could use one file descriptor and set the buffer type field
+   accordingly when calling :ref:`VIDIOC_QBUF` etc.,
+   but it makes the :ref:`select() <func-select>` function ambiguous. We also
+   like the clean approach of one file descriptor per logical stream.
+   Video overlay for example is also a logical stream, although the CPU
+   is not needed for continuous operation.
+
+.. [#f2]
+   Random enqueue order permits applications processing images out of
+   order (such as video codecs) to return buffers earlier, reducing the
+   probability of data loss. Random fill order allows drivers to reuse
+   buffers on a LIFO-basis, taking advantage of caches holding
+   scatter-gather lists and the like.
+
+.. [#f3]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+***************************
+Opening and Closing Devices
+***************************
+
+
+Device Naming
+=============
+
+V4L2 drivers are implemented as kernel modules, loaded manually by the
+system administrator or automatically when a device is first discovered.
+The driver modules plug into the "videodev" kernel module. It provides
+helper functions and a common application interface specified in this
+document.
+
+Each driver thus loaded registers one or more device nodes with major
+number 81 and a minor number between 0 and 255. Minor numbers are
+allocated dynamically unless the kernel is compiled with the kernel
+option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
+are allocated in ranges depending on the device node type (video, radio,
+etc.).
+
+Many drivers support "video_nr", "radio_nr" or "vbi_nr" module
+options to select specific video/radio/vbi node numbers. This allows the
+user to request that the device node is named e.g. /dev/video5 instead
+of leaving it to chance. When the driver supports multiple devices of
+the same type more than one device node number can be assigned,
+separated by commas:
+
+.. code-block:: none
+
+   # modprobe mydriver video_nr=0,1 radio_nr=0,1
+
+In ``/etc/modules.conf`` this may be written as:
+
+::
+
+    options mydriver video_nr=0,1 radio_nr=0,1
+
+When no device node number is given as module option the driver supplies
+a default.
+
+Normally udev will create the device nodes in /dev automatically for
+you. If udev is not installed, then you need to enable the
+CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to
+correctly relate a minor number to a device node number. I.e., you need
+to be certain that minor number 5 maps to device node name video5. With
+this kernel option different device types have different minor number
+ranges. These ranges are listed in :ref:`devices`.
+
+The creation of character special files (with mknod) is a privileged
+operation and devices cannot be opened by major and minor number. That
+means applications cannot *reliably* scan for loaded or installed
+drivers. The user must enter a device name, or the application can try
+the conventional device names.
+
+
+.. _related:
+
+Related Devices
+===============
+
+Devices can support several functions. For example video capturing, VBI
+capturing and radio support.
+
+The V4L2 API creates different nodes for each of these functions.
+
+The V4L2 API was designed with the idea that one device node could
+support all functions. However, in practice this never worked: this
+'feature' was never used by applications and many drivers did not
+support it and if they did it was certainly never tested. In addition,
+switching a device node between different functions only works when
+using the streaming I/O API, not with the
+:ref:`read() <func-read>`/\ :ref:`write() <func-write>` API.
+
+Today each device node supports just one function.
+
+Besides video input or output the hardware may also support audio
+sampling or playback. If so, these functions are implemented as ALSA PCM
+devices with optional ALSA audio mixer devices.
+
+One problem with all these devices is that the V4L2 API makes no
+provisions to find these related devices. Some really complex devices
+use the Media Controller (see :ref:`media_controller`) which can be
+used for this purpose. But most drivers do not use it, and while some
+code exists that uses sysfs to discover related devices (see
+libmedia_dev in the
+`v4l-utils <http://git.linuxtv.org/cgit.cgi/v4l-utils.git/>`__ git
+repository), there is no library yet that can provide a single API
+towards both Media Controller-based devices and devices that do not use
+the Media Controller. If you want to work on this please write to the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Multiple Opens
+==============
+
+V4L2 devices can be opened more than once. [#f1]_ When this is supported
+by the driver, users can for example start a "panel" application to
+change controls like brightness or audio volume, while another
+application captures video and audio. In other words, panel applications
+are comparable to an ALSA audio mixer application. Just opening a V4L2
+device should not change the state of the device. [#f2]_
+
+Once an application has allocated the memory buffers needed for
+streaming data (by calling the :ref:`VIDIOC_REQBUFS`
+or :ref:`VIDIOC_CREATE_BUFS` ioctls, or
+implicitly by calling the :ref:`read() <func-read>` or
+:ref:`write() <func-write>` functions) that application (filehandle)
+becomes the owner of the device. It is no longer allowed to make changes
+that would affect the buffer sizes (e.g. by calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl) and other applications are
+no longer allowed to allocate buffers or start or stop streaming. The
+EBUSY error code will be returned instead.
+
+Merely opening a V4L2 device does not grant exclusive access. [#f3]_
+Initiating data exchange however assigns the right to read or write the
+requested type of data, and to change related properties, to this file
+descriptor. Applications can request additional access privileges using
+the priority mechanism described in :ref:`app-pri`.
+
+
+Shared Data Streams
+===================
+
+V4L2 drivers should not support multiple applications reading or writing
+the same data stream on a device by copying buffers, time multiplexing
+or similar means. This is better handled by a proxy application in user
+space.
+
+
+Functions
+=========
+
+To open and close V4L2 devices applications use the
+:ref:`open() <func-open>` and :ref:`close() <func-close>` function,
+respectively. Devices are programmed using the
+:ref:`ioctl() <func-ioctl>` function as explained in the following
+sections.
+
+.. [#f1]
+   There are still some old and obscure drivers that have not been
+   updated to allow for multiple opens. This implies that for such
+   drivers :ref:`open() <func-open>` can return an ``EBUSY`` error code
+   when the device is already in use.
+
+.. [#f2]
+   Unfortunately, opening a radio device often switches the state of the
+   device to radio mode in many drivers. This behavior should be fixed
+   eventually as it violates the V4L2 specification.
+
+.. [#f3]
+   Drivers could recognize the ``O_EXCL`` open flag. Presently this is
+   not required, so applications cannot know if it really works.

+**********************
+Standard Image Formats
+**********************
+
+In order to exchange images between drivers and applications, it is
+necessary to have standard image data formats which both sides will
+interpret the same way. V4L2 includes several such formats, and this
+section is intended to be an unambiguous specification of the standard
+image data formats in V4L2.
+
+V4L2 drivers are not limited to these formats, however. Driver-specific
+formats are possible. In that case the application may depend on a codec
+to convert images to one of the standard formats when needed. But the
+data can still be stored and retrieved in the proprietary format. For
+example, a device may support a proprietary compressed format.
+Applications can still capture and save the data in the compressed
+format, saving much disk space, and later use a codec to convert the
+images to the X Windows screen format when the video is to be displayed.
+
+Even so, ultimately, some standard formats are needed, so the V4L2
+specification would not be complete without well-defined standard
+formats.
+
+The V4L2 standard formats are mainly uncompressed formats. The pixels
+are always arranged in memory from left to right, and from top to
+bottom. The first byte of data in the image buffer is always for the
+leftmost pixel of the topmost row. Following that is the pixel
+immediately to its right, and so on until the end of the top row of
+pixels. Following the rightmost pixel of the row there may be zero or
+more bytes of padding to guarantee that each row of pixel data has a
+certain alignment. Following the pad bytes, if any, is data for the
+leftmost pixel of the second row from the top, and so on. The last row
+has just as many pad bytes after it as the other rows.
+
+In V4L2 each format has an identifier which looks like ``PIX_FMT_XXX``,
+defined in the :ref:`videodev2.h <videodev>` header file. These
+identifiers represent
+:ref:`four character (FourCC) codes <v4l2-fourcc>` which are also
+listed below, however they are not the same as those used in the Windows
+world.
+
+For some formats, data is stored in separate, discontiguous memory
+buffers. Those formats are identified by a separate set of FourCC codes
+and are referred to as "multi-planar formats". For example, a
+:ref:`YUV422 <V4L2-PIX-FMT-YUV422M>` frame is normally stored in one
+memory buffer, but it can also be placed in two or three separate
+buffers, with Y component in one buffer and CbCr components in another
+in the 2-planar version or with each component in its own buffer in the
+3-planar case. Those sub-buffers are referred to as "*planes*".

+Infrared 10-bit linked with Depth 16-bit images
+
+
+Description
+===========
+
+Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
+Infrared image followed by Depth data. The pixel definition is 32-bpp,
+with the Depth and Infrared Data split into separate continuous planes of
+identical dimensions.
+
+
+
+The first plane - Infrared data - is stored according to
+:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
+Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
+with values in range 0 to 1023.
+The six remaining MSBs are padded with zeros.
+
+
+The second plane provides 16-bit per-pixel Depth data arranged in
+:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
+
+
+**Frame Structure.**
+Each cell is a 16-bit word with more significant data stored at higher
+memory address (byte order is little-endian).

+
+
+Description
+===========
+
+M420 is a YUV format with ½ horizontal and vertical chroma subsampling
+(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
+Two lines of luma data are followed by one line of chroma data.
+
+The luma plane has one byte per pixel. The chroma plane contains
+interleaved CbCr pixels subsampled by ½ in the horizontal and vertical
+directions. Each CbCr pair belongs to four pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, Y'\ :sub:`11`.
+
+All line lengths are identical: if the Y lines include pad bytes so do
+the CbCr lines.

+Intel D4xx UVC Cameras Metadata
+
+
+Description
+===========
+
+Intel D4xx (D435 and other) cameras include per-frame metadata in their UVC
+payload headers, following the Microsoft(R) UVC extension proposal [1_]. That
+means, that the private D4XX metadata, following the standard UVC header, is
+organised in blocks. D4XX cameras implement several standard block types,
+proposed by Microsoft, and several proprietary ones. Supported standard metadata
+types are MetadataId_CaptureStats (ID 3), MetadataId_CameraExtrinsics (ID 4),
+and MetadataId_CameraIntrinsics (ID 5). For their description see [1_]. This
+document describes proprietary metadata types, used by D4xx cameras.
+
+V4L2_META_FMT_D4XX buffers follow the metadata buffer layout of
+V4L2_META_FMT_UVC with the only difference, that it also includes proprietary
+payload header data. D4xx cameras use bulk transfers and only send one payload
+per frame, therefore their headers cannot be larger than 255 bytes.
+
+Below are proprietary Microsoft style metadata types, used by D4xx cameras,
+where all fields are in little endian order:

+3A statistics
+=============
+
+The IPU3 ImgU 3A statistics accelerators collect different statistics over
+an input Bayer frame. Those statistics are obtained from the "ipu3-imgu [01] 3a
+stat" metadata capture video nodes, using the :c:type:`v4l2_meta_format`
+interface. They are formatted as described by the :c:type:`ipu3_uapi_stats_3a`
+structure.
+
+The statistics collected are AWB (Auto-white balance) RGBS (Red, Green, Blue and
+Saturation measure) cells, AWB filter response, AF (Auto-focus) filter response,
+and AE (Auto-exposure) histogram.
+
+The struct :c:type:`ipu3_uapi_4a_config` saves all configurable parameters.

+UVC Payload Header Data
+
+
+Description
+===========
+
+This format describes standard UVC metadata, extracted from UVC packet headers
+and provided by the UVC driver through metadata video nodes. That data includes
+exact copies of the standard part of UVC Payload Header contents and auxiliary
+timing information, required for precise interpretation of timestamps, contained
+in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
+the "UVC 1.5 Class specification" for details.
+
+Each UVC payload header can be between 2 and 12 bytes large. Buffers can
+contain multiple headers, if multiple such headers have been transmitted by the
+camera for the respective frame. However, the driver may drop headers when the
+buffer is full, when they contain no useful information (e.g. those without the
+SCR field or with that field identical to the previous header), or generally to
+perform rate limiting when the device sends a large number of headers.
+
+Each individual block contains the following fields:
+
+.. flat-table:: UVC Metadata Block

+
+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1 1-D
+Histogram (HGO) engine.
+
+The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
+or HSV data. It operates on a possibly cropped and subsampled input image and
+computes the minimum, maximum and sum of all pixels as well as per-channel
+histograms.
+
+The HGO can compute histograms independently per channel, on the maximum of the
+three channels (RGB data only) or on the Y channel only (YCbCr only). It can
+additionally output the histogram with 64 or 256 bins, resulting in four
+possible modes of operation.
+
+- In *64 bins normal mode*, the HGO operates on the three channels independently
+  to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
+  supported.
+- In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 64-bins histogram. Only the RGB image format is
+  supported.
+- In *256 bins normal mode*, the HGO operates on the Y channel to compute a
+  single 256-bins histogram. Only the YCbCr image format is supported.
+- In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 256-bins histogram. Only the RGB image format is
+  supported.
+
+**Byte Order.**

+contains one byte.

+
+
+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1
+2-D Histogram (HGT) engine.
+
+The VSP1 HGT is a histogram computation engine that operates on HSV
+data. It operates on a possibly cropped and subsampled input image and
+computes the sum, maximum and minimum of the S component as well as a
+weighted frequency histogram based on the H and S components.
+
+The histogram is a matrix of 6 Hue and 32 Saturation buckets, 192 in
+total. Each HSV value is added to one or more buckets with a weight
+between 1 and 16 depending on the Hue areas configuration. Finding the
+corresponding buckets is done by inspecting the H and S value independently.
+
+The Saturation position **n** (0 - 31) of the bucket in the matrix is
+found by the expression:
+
+    n = S / 8
+
+The Hue position **m** (0 - 5) of the bucket in the matrix depends on
+how the HGT Hue areas are configured. There are 6 user configurable Hue
+Areas which can be configured to cover overlapping Hue values:

+
+When two consecutive areas don't overlap (n+1L is equal to nU) the boundary
+value is considered as part of the lower area.
+
+Pixels with a hue value included in the centre of an area (between nL and nU
+included) are attributed to that single area and given a weight of 16. Pixels
+with a hue value included in the overlapping region between two areas (between
+n+1L and nU excluded) are attributed to both areas and given a weight for each
+of these areas proportional to their position along the diagonal lines
+(rounded down).
+
+The Hue area setup must match one of the following constrains:
+
+::
+
+    0L <= 0U <= 1L <= 1U <= 2L <= 2U <= 3L <= 3U <= 4L <= 4U <= 5L <= 5U

+V4L2_PIX_FMT_NV21
+Formats with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:2:0 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
+combined CbCr plane immediately follows the Y plane in memory. The CbCr
+plane is the same width, in bytes, as the Y plane (and of the image),
+but is half as tall in pixels. Each CbCr pair belongs to four pixels.
+For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
+Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`. ``V4L2_PIX_FMT_NV21`` is
+the same except the Cb and Cr bytes are swapped, the CrCb plane starts
+with a Cr byte.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+Variation of ``V4L2_PIX_FMT_NV12`` and ``V4L2_PIX_FMT_NV21`` with planes
+non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
+three components are separated into two sub-images or planes.
+``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
+two planes are non-contiguous in memory, i.e. the chroma plane do not
+necessarily immediately follows the luma plane. The luminance data
+occupies the first plane. The Y plane has one byte per pixel. In the
+second plane there is a chrominance data with alternating chroma
+samples. The CbCr plane is the same width, in bytes, as the Y plane (and
+of the image), but is half as tall in pixels. Each CbCr pair belongs to
+four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
+Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
+``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
+``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
+arranged in 16x16 2D tiles and tiles are arranged in linear order in
+memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
+except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
+byte.
+
+``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
+applications that support the multi-planar API, described in
+:ref:`planar-apis`.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+
+Formats with ½ horizontal and vertical chroma resolution. This format
+has two planes - one for luminance and one for chrominance. Chroma
+samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
+memory layout. Pixels are grouped in macroblocks of 64x32 size. The
+order of macroblocks in memory is also not standard.
+
+
+Description
+===========
+
+This is the two-plane versions of the YUV 4:2:0 format where data is
+grouped into 64x32 macroblocks. The three components are separated into
+two sub-images or planes. The Y plane has one byte per pixel and pixels
+are grouped into 64x32 macroblocks. The CbCr plane has the same width,
+in bytes, as the Y plane (and the image), but is half as tall in pixels.
+The chroma plane is also grouped into 64x32 macroblocks.
+
+Width of the buffer has to be aligned to the multiple of 128, and height
+alignment is 32. Every four adjacent buffers - two horizontally and two
+vertically are grouped together and are located in memory in Z or
+flipped Z order.
+
+Layout of macroblocks in memory is presented in the following figure.

+
+    V4L2_PIX_FMT_NV12MT macroblock Z shape memory layout
+
+The requirement that width is multiple of 128 is implemented because,
+the Z shape cannot be cut in half horizontally. In case the vertical
+resolution of macroblocks is odd then the last row of macroblocks is
+arranged in a linear order.
+
+In case of chroma the layout is identical. Cb and Cr samples are
+interleaved. Height of the buffer is aligned to 32.

+Variation of ``V4L2_PIX_FMT_NV16`` and ``V4L2_PIX_FMT_NV61`` with planes
+non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar, two-plane version of the YUV 4:2:2 format. The
+three components are separated into two sub-images or planes.
+``V4L2_PIX_FMT_NV16M`` differs from ``V4L2_PIX_FMT_NV16`` in that the
+two planes are non-contiguous in memory, i.e. the chroma plane does not
+necessarily immediately follow the luma plane. The luminance data
+occupies the first plane. The Y plane has one byte per pixel. In the
+second plane there is chrominance data with alternating chroma samples.
+The CbCr plane is the same width and height, in bytes, as the Y plane.
+Each CbCr pair belongs to two pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`.
+``V4L2_PIX_FMT_NV61M`` is the same as ``V4L2_PIX_FMT_NV16M`` except the
+Cb and Cr bytes are swapped, the CrCb plane starts with a Cr byte.
+
+``V4L2_PIX_FMT_NV16M`` and ``V4L2_PIX_FMT_NV61M`` are intended to be
+used only in drivers and applications that support the multi-planar API,
+described in :ref:`planar-apis`.
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_NV42
+Formats with full horizontal and vertical chroma resolutions, also known
+as YUV 4:4:4. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:4:4 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first, with each Y sample stored in one byte per pixel. For
+``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y
+plane in memory. The CbCr plane has the same width and height, in
+pixels, as the Y plane (and the image). Each line contains one CbCr pair
+per pixel, with each Cb and Cr sample stored in one byte.
+``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are
+swapped, the CrCb plane starts with a Cr sample.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has
+twice as many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+
+      - ``V4L2_PIX_FMT_S5C_UYVY_JPG``
+      - 'S5CI'
+      - Two-planar format used by Samsung S5C73MX cameras. The first plane
+	contains interleaved JPEG and UYVY image data, followed by meta
+	data in form of an array of offsets to the UYVY data blocks. The
+	actual pointer array follows immediately the interleaved JPEG/UYVY
+	data, the number of entries in this array equals the height of the
+	UYVY image. Each entry is a 4-byte unsigned integer in big endian
+	order and it's an offset to a single pixel line of the UYVY image.
+	The first plane can start either with JPEG or UYVY data chunk. The
+	size of a single UYVY block equals the UYVY image's width
+	multiplied by 2. The size of a JPEG chunk depends on the image and
+	can vary with each line.
+
+	The second plane, at an offset of 4084 bytes, contains a 4-byte
+	offset to the pointer array in the first plane. This offset is
+	followed by a 4-byte value indicating size of the pointer array.
+	All numbers in the second plane are also in big endian order.
+	Remaining data in the second plane is undefined. The information
+	in the second plane allows to easily find location of the pointer
+	array, which can be different for each frame. The size of the
+	pointer array is constant for given UYVY image height.
+
+	In order to extract UYVY and JPEG frames an application can
+	initially set a data pointer to the start of first plane and then
+	add an offset from the first entry of the pointers table. Such a
+	pointer indicates start of an UYVY image pixel line. Whole UYVY
+	line can be copied to a separate buffer. These steps should be
+	repeated for each line, i.e. the number of entries in the pointer
+	array. Anything what's in between the UYVY lines is JPEG data and
+	should be concatenated to form the JPEG stream.

+
+      - ``V4L2_PIX_FMT_MT21C``
+      - 'MT21'
+      - Compressed two-planar YVU420 format used by Mediatek MT8173.
+	The compression is lossless.
+	It is an opaque intermediate format and the MDP hardware must be
+	used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,
+	``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``.
+    * .. _V4L2-PIX-FMT-SUNXI-TILED-NV12:
+
+      - ``V4L2_PIX_FMT_SUNXI_TILED_NV12``
+      - 'ST12'
+      - Two-planar NV12-based format used by the video engine found on Allwinner
+	(codenamed sunxi) platforms, with 32x32 tiles for the luminance plane
+	and 32x64 tiles for the chrominance plane. The data in each tile is
+	stored in linear order, within the tile bounds. Each tile follows the
+	previous one linearly in memory (from left to right, top to bottom).
+
+	The associated buffer dimensions are aligned to match an integer number
+	of tiles, resulting in 32-aligned resolutions for the luminance plane
+	and 16-aligned resolutions for the chrominance plane (with 2x2
+	subsampling).

+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+.. note:: Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.

+10-bit Bayer formats
+
+Description
+===========
+
+These four pixel formats are used by Intel IPU3 driver, they are raw
+sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
+to 32 bytes leaving 6 most significant bits padding in the last byte.
+The format is little endian.
+
+In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
+Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
+
+**Byte Order.**
+Each cell is one byte.

+10-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+sample. Each sample is stored in a 16-bit word, with 6 unused
+high bits filled with zeros. Each n-pixel row contains n/2 green samples and
+n/2 blue or red samples, with alternating red and blue rows. Bytes are
+stored in memory in little endian order. They are conventionally described
+as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of
+these formats:
+
+**Byte Order.**
+Each cell is one byte, the 6 most significant bits in the high bytes
+are 0.

+16-bit Bayer formats
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 16 bits per
+sample. Each sample is stored in a 16-bit word. Each n-pixel row contains
+n/2 green samples and n/2 blue or red samples, with alternating red and blue
+rows. Bytes are stored in memory in little endian order. They are
+conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is
+an example of a small V4L2_PIX_FMT_SBGGR16 image:

+      - Image height in pixels. If ``field`` is one of ``V4L2_FIELD_TOP``,
+	``V4L2_FIELD_BOTTOM`` or ``V4L2_FIELD_ALTERNATE`` then height
+	refers to the number of lines in the field, otherwise it refers to
+	the number of lines in the frame (which is twice the field height
+	for interlaced formats).
+    * - :cspan:`2` Applications set these fields to request an image
+	size, drivers return the closest possible values. In case of
+	planar formats the ``width`` and ``height`` applies to the largest
+	plane. To avoid ambiguities drivers must return values rounded up
+	to a multiple of the scale factor of any smaller planes. For
+	example when the image format is YUV 4:2:0, ``width`` and
+	``height`` must be multiples of two.
+
+	For compressed formats that contain the resolution information encoded
+	inside the stream, when fed to a stateful mem2mem decoder, the fields
+	may be zero to rely on the decoder to detect the right values. For more
+	details see :ref:`decoder` and format descriptions.
+    * - __u32
+      - ``pixelformat``
+      - The pixel format or type of compression, set by the application.
+	This is a little endian
+	:ref:`four character code <v4l2-fourcc>`. V4L2 defines standard
+	RGB formats in :ref:`pixfmt-rgb`, YUV formats in
+	:ref:`yuv-formats`, and reserved codes in
+	:ref:`reserved-formats`
+    * - __u32
+      - ``field``
+      - Field order, from enum :c:type:`v4l2_field`.
+        Video images are typically interlaced. Applications can request to
+	capture or output only the top or bottom field, or both fields
+	interlaced or sequentially stored in one buffer or alternating in
+	separate buffers. Drivers return the actual field order selected.
+	For more details on fields see :ref:`field-order`.
+    * - __u32
+      - ``bytesperline``
+      - Distance in bytes between the leftmost pixels in two adjacent
+	lines.
+    * - :cspan:`2`
+
+	Both applications and drivers can set this field to request
+	padding bytes at the end of each line. Drivers however may ignore
+	the value requested by the application, returning ``width`` times
+	bytes per pixel or a larger value required by the hardware. That
+	implies applications can just set this field to zero to get a
+	reasonable default.
+
+	Video hardware may access padding bytes, therefore they must
+	reside in accessible memory. Consider cases where padding bytes
+	after the last line of an image cross a system page boundary.
+	Input devices may write padding bytes, the value is undefined.
+	Output devices ignore the contents of padding bytes.
+
+	When the image format is planar the ``bytesperline`` value applies
+	to the first plane and is divided by the same factor as the
+	``width`` field for the other planes. For example the Cb and Cr
+	planes of a YUV 4:2:0 image have half as many padding bytes
+	following each line as the Y plane. To avoid ambiguities drivers
+	must return a ``bytesperline`` value rounded up to a multiple of
+	the scale factor.
+
+	For compressed formats the ``bytesperline`` value makes no sense.
+	Applications and drivers must set this to 0 in that case.
+    * - __u32
+      - ``sizeimage``
+      - Size in bytes of the buffer to hold a complete image, set by the
+	driver. Usually this is ``bytesperline`` times ``height``. When
+	the image consists of variable length compressed data this is the
+	number of bytes required by the codec to support the worst-case
+	compression scenario.
+
+	The driver will set the value for uncompressed images.
+
+	Clients are allowed to set the sizeimage field for variable length
+	compressed data flagged with ``V4L2_FMT_FLAG_COMPRESSED`` at
+	:ref:`VIDIOC_ENUM_FMT`, but the driver may ignore it and set the
+	value itself, or it may modify the provided value based on
+	alignment requirements or minimum/maximum size requirements.
+	If the client wants to leave this to the driver, then it should
+	set sizeimage to 0.
+    * - __u32
+      - ``colorspace``
+      - Image colorspace, from enum :c:type:`v4l2_colorspace`.
+        This information supplements the ``pixelformat`` and must be set
+	by the driver for capture streams and by the application for
+	output streams, see :ref:`colorspaces`.
+    * - __u32
+      - ``priv``
+      - This field indicates whether the remaining fields of the
+	struct :c:type:`v4l2_pix_format`, also called the
+	extended fields, are valid. When set to
+	``V4L2_PIX_FMT_PRIV_MAGIC``, it indicates that the extended fields
+	have been correctly initialized. When set to any other value it
+	indicates that the extended fields contain undefined values.
+
+	Applications that wish to use the pixel format extended fields
+	must first ensure that the feature is supported by querying the
+	device for the :ref:`V4L2_CAP_EXT_PIX_FORMAT <querycap>`
+	capability. If the capability isn't set the pixel format extended
+	fields are not supported and using the extended fields will lead
+	to undefined results.
+
+	To use the extended fields, applications must set the ``priv``
+	field to ``V4L2_PIX_FMT_PRIV_MAGIC``, initialize all the extended
+	fields and zero the unused bytes of the
+	struct :c:type:`v4l2_format` ``raw_data`` field.
+
+	When the ``priv`` field isn't set to ``V4L2_PIX_FMT_PRIV_MAGIC``
+	drivers must act as if all the extended fields were set to zero.
+	On return drivers must set the ``priv`` field to
+	``V4L2_PIX_FMT_PRIV_MAGIC`` and all the extended fields to
+	applicable values.

+Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1
+
+
+Description
+===========
+
+In this format each 12 bytes is eight pixels. In the twelve bytes are
+two CbCr pairs and eight Y's. The first CbCr pair goes with the first
+four Y's, and the second CbCr pair goes with the other four Y's. The Cb
+and Cr components have one fourth the horizontal resolution of the Y
+component.
+
+Do not confuse this format with
+:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
+from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1
+*planar*".
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_YUV410
+Planar formats with ¼ horizontal and vertical chroma resolution, also
+known as YUV 4:1:0
+
+
+Description
+===========
+
+These are planar formats, as opposed to a packed format. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
+the Cr plane immediately follows the Y plane in memory. The Cr plane is
+¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
+belongs to 16 pixels, a four-by-four square of the image. Following the
+Cr plane is the Cb plane, just like the Cr plane.
+``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
+then the Cr plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four Cx rows
+(including padding) are exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.

+Description
+===========
+
+This format is not commonly used. This is a planar format similar to the
+4:2:2 planar format except with half as many chroma. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. The Cb plane immediately
+follows the Y plane in memory. The Cb plane is ¼ the width of the Y
+plane (and of the image). Each Cb belongs to 4 pixels all on the same
+row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane,
+just like the Cb plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four C x rows
+(including padding) is exactly as long as one Y row (including padding).

+V4L2_PIX_FMT_YVU420M
+Variation of ``V4L2_PIX_FMT_YUV420`` and ``V4L2_PIX_FMT_YVU420`` with
+planes non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar format, as opposed to a packed format. The three
+components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. For
+``V4L2_PIX_FMT_YUV420M`` the Cb data constitutes the second plane which
+is half the width and half the height of the Y plane (and of the image).
+Each Cb belongs to four pixels, a two-by-two square of the image. For
+example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, and Y'\ :sub:`11`. The Cr data, just like the Cb plane,
+is in the third plane.
+
+``V4L2_PIX_FMT_YVU420M`` is the same except the Cr data is stored in the
+second plane and the Cb data in the third plane.
+
+If the Y plane has pad bytes after each row, then the Cb and Cr planes
+have half as many pad bytes after their rows. In other words, two Cx
+rows (including padding) is exactly as long as one Y row (including
+padding).
+
+``V4L2_PIX_FMT_YUV420M`` and ``V4L2_PIX_FMT_YVU420M`` are intended to be
+used only in drivers and applications that support the multi-planar API,
+described in :ref:`planar-apis`.
+
+**Byte Order.**
+Each cell is one byte.

+*****************************
+Single- and multi-planar APIs
+*****************************
+
+Some devices require data for each input or output video frame to be
+placed in discontiguous memory buffers. In such cases, one video frame
+has to be addressed using more than one memory address, i.e. one pointer
+per "plane". A plane is a sub-buffer of the current frame. For examples
+of such formats see :ref:`pixfmt`.
+
+Initially, V4L2 API did not support multi-planar buffers and a set of
+extensions has been introduced to handle them. Those extensions
+constitute what is being referred to as the "multi-planar API".
+
+Some of the V4L2 API calls and structures are interpreted differently,
+depending on whether single- or multi-planar API is being used. An
+application can choose whether to use one or the other by passing a
+corresponding buffer type to its ioctl calls. Multi-planar versions of
+buffer types are suffixed with an ``_MPLANE`` string. For a list of
+available multi-planar buffer types see enum
+:c:type:`v4l2_buf_type`.
+
+
+Multi-planar formats
+====================
+
+Multi-planar API introduces new multi-planar formats. Those formats use
+a separate set of FourCC codes. It is important to distinguish between
+the multi-planar API and a multi-planar format. Multi-planar API calls
+can handle all single-planar formats as well (as long as they are passed
+in multi-planar API structures), while the single-planar API cannot
+handle multi-planar formats.
+
+
+Calls that distinguish between single and multi-planar APIs
+===========================================================
+
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>`
+    Two additional multi-planar capabilities are added. They can be set
+    together with non-multi-planar ones for devices that handle both
+    single- and multi-planar formats.
+
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`
+    New structures for describing multi-planar formats are added: struct
+    :c:type:`v4l2_pix_format_mplane` and
+    struct :c:type:`v4l2_plane_pix_format`.
+    Drivers may define new multi-planar formats, which have distinct
+    FourCC codes from the existing single-planar ones.
+
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>`
+    A new struct :c:type:`v4l2_plane` structure for
+    describing planes is added. Arrays of this structure are passed in
+    the new ``m.planes`` field of struct
+    :c:type:`v4l2_buffer`.
+
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+    Will allocate multi-planar buffers as requested.

+*********************
+Querying Capabilities
+*********************
+
+Because V4L2 covers a wide variety of devices not all aspects of the API
+are equally applicable to all types of devices. Furthermore devices of
+the same type have different capabilities and this specification permits
+the omission of a few complicated and less important parts of the API.
+
+The :ref:`VIDIOC_QUERYCAP` ioctl is available to
+check if the kernel device is compatible with this specification, and to
+query the :ref:`functions <devices>` and :ref:`I/O methods <io>`
+supported by the device.
+
+Starting with kernel version 3.1, :ref:`VIDIOC_QUERYCAP`
+will return the V4L2 API version used by the driver, with generally
+matches the Kernel version. There's no need of using
+:ref:`VIDIOC_QUERYCAP` to check if a specific ioctl
+is supported, the V4L2 core now returns ``ENOTTY`` if a driver doesn't
+provide support for an ioctl.
+
+Other features can be queried by calling the respective ioctl, for
+example :ref:`VIDIOC_ENUMINPUT` to learn about the
+number, types and names of video connectors on the device. Although
+abstraction is a major objective of this API, the
+:ref:`VIDIOC_QUERYCAP` ioctl also allows driver
+specific applications to reliably identify the driver.
+
+All V4L2 drivers must support :ref:`VIDIOC_QUERYCAP`.
+Applications should always call this ioctl after opening the device.

+Read/Write
+**********
+
+Input and output devices support the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function, respectively, when the
+``V4L2_CAP_READWRITE`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set.
+
+Drivers may need the CPU to copy the data, but they may also support DMA
+to or from user memory, so this I/O method is not necessarily less
+efficient than other methods merely exchanging buffer pointers. It is
+considered inferior though because no meta-information like frame
+counters or timestamps are passed. This information is necessary to
+recognize frame dropping and to synchronize with other data streams.
+However this is also the simplest I/O method, requiring little or no
+setup to exchange data. It permits command line stunts like this (the
+vidctrl tool is fictitious):
+
+
+.. code-block:: none
+
+    $ vidctrl /dev/video --input=0 --format=YUYV --size=352x288
+    $ dd if=/dev/video of=myimage.422 bs=202752 count=1
+
+To read from the device applications use the :ref:`read() <func-read>`
+function, to write the :ref:`write() <func-write>` function. Drivers
+must implement one I/O method if they exchange data with applications,
+but it need not be this. [#f1]_ When reading or writing is supported, the
+driver must also support the :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   It would be desirable if applications could depend on drivers
+   supporting all I/O interfaces, but as much as the complex memory
+   mapping I/O can be inadequate for some devices we have no reason to
+   require this interface, which is most useful for simple applications
+   capturing still images.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.

+*************
+Configuration
+*************
+
+Applications can use the :ref:`selection API <VIDIOC_G_SELECTION>` to
+select an area in a video signal or a buffer, and to query for default
+settings and hardware limits.
+
+Video hardware can have various cropping, composing and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in the horizontal and
+vertical directions. Also it may not support scaling at all. At the same
+time the cropping/composing rectangles may have to be aligned, and both
+the source and the sink may have arbitrary upper and lower size limits.
+Therefore, as usual, drivers are expected to adjust the requested
+parameters and return the actual values selected. An application can
+control the rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+
+Configuration of video capture
+==============================
+
+See figure :ref:`sel-targets-capture` for examples of the selection
+targets available for a video capture device. It is recommended to
+configure the cropping targets before to the composing targets.
+
+The range of coordinates of the top left corner, width and height of
+areas that can be sampled is given by the ``V4L2_SEL_TGT_CROP_BOUNDS``
+target. It is recommended for the driver developers to put the top/left
+corner at position ``(0,0)``. The rectangle's coordinates are expressed
+in pixels.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by the ``V4L2_SEL_TGT_CROP`` target.
+It uses the same coordinate system as ``V4L2_SEL_TGT_CROP_BOUNDS``. The
+active cropping area must lie completely inside the capture boundaries.
+The driver may further adjust the requested size and/or position
+according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``V4L2_SEL_TGT_CROP_DEFAULT`` target. This rectangle shall cover what the
+driver writer considers the complete picture. Drivers shall set the
+active crop rectangle to the default when the driver is first loaded,
+but not later.
+
+The composing targets refer to a memory buffer. The limits of composing
+coordinates are obtained using ``V4L2_SEL_TGT_COMPOSE_BOUNDS``. All
+coordinates are expressed in pixels. The rectangle's top/left corner
+must be located at position ``(0,0)``. The width and height are equal to
+the image size set by :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+The part of a buffer into which the image is inserted by the hardware is
+controlled by the ``V4L2_SEL_TGT_COMPOSE`` target. The rectangle's
+coordinates are also expressed in the same coordinate system as the
+bounds rectangle. The composing rectangle must lie completely inside
+bounds rectangle. The driver must adjust the composing rectangle to fit
+to the bounding limits. Moreover, the driver can perform other
+adjustments according to hardware limitations. The application can
+control rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+For capture devices the default composing rectangle is queried using
+``V4L2_SEL_TGT_COMPOSE_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a buffer that is modified by the hardware is given by
+``V4L2_SEL_TGT_COMPOSE_PADDED``. It contains all pixels defined using
+``V4L2_SEL_TGT_COMPOSE`` plus all padding data modified by hardware
+during insertion process. All pixels outside this rectangle *must not*
+be changed by the hardware. The content of pixels that lie inside the
+padded area but outside active area is undefined. The application can
+use the padded and active rectangles to detect where the rubbish pixels
+are located and remove them if needed.
+
+
+Configuration of video output
+=============================
+
+For output devices targets and ioctls are used similarly to the video
+capture case. The *composing* rectangle refers to the insertion of an
+image into a video signal. The cropping rectangles refer to a memory
+buffer. It is recommended to configure the composing targets before to
+the cropping targets.
+
+The cropping targets refer to the memory buffer that contains an image
+to be inserted into a video signal or graphical screen. The limits of
+cropping coordinates are obtained using ``V4L2_SEL_TGT_CROP_BOUNDS``.
+All coordinates are expressed in pixels. The top/left corner is always
+point ``(0,0)``. The width and height is equal to the image size
+specified using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The top left corner, width and height of the source rectangle, that is
+the area from which image date are processed by the hardware, is given
+by the ``V4L2_SEL_TGT_CROP``. Its coordinates are expressed in in the
+same coordinate system as the bounds rectangle. The active cropping area
+must lie completely inside the crop boundaries and the driver may
+further adjust the requested size and/or position according to hardware
+limitations.
+
+For output devices the default cropping rectangle is queried using
+``V4L2_SEL_TGT_CROP_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a video signal or graphics display where the image is
+inserted by the hardware is controlled by ``V4L2_SEL_TGT_COMPOSE``
+target. The rectangle's coordinates are expressed in pixels. The
+composing rectangle must lie completely inside the bounds rectangle. The
+driver must adjust the area to fit to the bounding limits. Moreover, the
+driver can perform other adjustments according to hardware limitations.
+
+The device has a default composing rectangle, given by the
+``V4L2_SEL_TGT_COMPOSE_DEFAULT`` target. This rectangle shall cover what
+the driver writer considers the complete picture. It is recommended for
+the driver developers to put the top/left corner at position ``(0,0)``.
+Drivers shall set the active composing rectangle to the default one when
+the driver is first loaded.
+
+The devices may introduce additional content to video signal other than
+an image from memory buffers. It includes borders around an image.
+However, such a padded area is driver-dependent feature not covered by
+this document. Driver developers are encouraged to keep padded rectangle
+equal to active one. The padded target is accessed by the
+``V4L2_SEL_TGT_COMPOSE_PADDED`` identifier. It must contain all pixels
+from the ``V4L2_SEL_TGT_COMPOSE`` target.
+
+
+Scaling control
+===============
+
+An application can detect if scaling is performed by comparing the width
+and the height of rectangles obtained using ``V4L2_SEL_TGT_CROP`` and
+``V4L2_SEL_TGT_COMPOSE`` targets. If these are not equal then the
+scaling is applied. The application can compute the scaling ratios using
+these values.

+Introduction
+************
+
+Some video capture devices can sample a subsection of a picture and
+shrink or enlarge it to an image of arbitrary size. Next, the devices
+can insert the image into larger one. Some video output devices can crop
+part of an input image, scale it up or down and insert it at an
+arbitrary scan line and horizontal offset into a video signal. We call
+these abilities cropping, scaling and composing.
+
+On a video *capture* device the source is a video signal, and the
+cropping target determine the area actually sampled. The sink is an
+image stored in a memory buffer. The composing area specifies which part
+of the buffer is actually written to by the hardware.
+
+On a video *output* device the source is an image in a memory buffer,
+and the cropping target is a part of an image to be shown on a display.
+The sink is the display or the graphics screen. The application may
+select the part of display where the image should be displayed. The size
+and position of such a window is controlled by the compose target.
+
+Rectangles for all cropping and composing targets are defined even if
+the device does supports neither cropping nor composing. Their size and
+position will be fixed in such a case. If the device does not support
+scaling then the cropping and composing rectangles have the same size.

+********************************
+Comparison with old cropping API
+********************************
+
+The selection API was introduced to cope with deficiencies of the
+older :ref:`CROP API <crop>`, that was designed to control simple
+capture devices. Later the cropping API was adopted by video output
+drivers. The ioctls are used to select a part of the display were the
+video signal is inserted. It should be considered as an API abuse
+because the described operation is actually the composing. The
+selection API makes a clear distinction between composing and cropping
+operations by setting the appropriate targets.
+
+The CROP API lacks any support for composing to and cropping from an
+image inside a memory buffer. The application could configure a
+capture device to fill only a part of an image by abusing V4L2
+API. Cropping a smaller image from a larger one is achieved by setting
+the field ``bytesperline`` at struct :c:type:`v4l2_pix_format`.
+Introducing an image offsets could be done by modifying field
+``m_userptr`` at struct :c:type:`v4l2_buffer` before calling
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`. Those operations should be avoided
+because they are not portable (endianness), and do not work for
+macroblock and Bayer formats and mmap buffers.
+
+The selection API deals with configuration of buffer
+cropping/composing in a clear, intuitive and portable way. Next, with
+the selection API the concepts of the padded target and constraints
+flags are introduced. Finally, struct :c:type:`v4l2_crop` and struct
+:c:type:`v4l2_cropcap` have no reserved fields. Therefore there is no
+way to extend their functionality. The new struct
+:c:type:`v4l2_selection` provides a lot of place for future
+extensions.
+
+Driver developers are encouraged to implement only selection API. The
+former cropping API would be simulated using the new one.

+similar, there's one fundamental difference between the two. On
+sub-device API, the selection rectangle refers to the media bus format,
+and is bound to a sub-device's pad. On the V4L2 interface the selection
+rectangles refer to the in-memory pixel format.
+
+This section defines the common definitions of the selection interfaces

+Video Standards
+***************
+
+Video devices typically support one or more different video standards or
+variations of standards. Each video input and output may support another
+set of standards. This set is reported by the ``std`` field of struct
+:c:type:`v4l2_input` and struct
+:c:type:`v4l2_output` returned by the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctls, respectively.
+
+V4L2 defines one bit for each analog video standard currently in use
+worldwide, and sets aside bits for driver defined standards, e. g.
+hybrid standards to watch NTSC video tapes on PAL TVs and vice versa.
+Applications can use the predefined bits to select a particular
+standard, although presenting the user a menu of supported standards is
+preferred. To enumerate and query the attributes of the supported
+standards applications use the :ref:`VIDIOC_ENUMSTD`
+ioctl.
+
+Many of the defined standards are actually just variations of a few
+major standards. The hardware may in fact not distinguish between them,
+or do so internal and switch automatically. Therefore enumerated
+standards also contain sets of one or more standard bits.
+
+Assume a hypothetic tuner capable of demodulating B/PAL, G/PAL and I/PAL
+signals. The first enumerated standard is a set of B and G/PAL, switched
+automatically depending on the selected radio frequency in UHF or VHF
+band. Enumeration gives a "PAL-B/G" or "PAL-I" choice. Similar a
+Composite input may collapse standards, enumerating "PAL-B/G/H/I",
+"NTSC-M" and "SECAM-D/K". [#f1]_
+
+To query and select the standard used by the current video input or
+output applications call the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctl, respectively. The
+*received* standard can be sensed with the
+:ref:`VIDIOC_QUERYSTD` ioctl.
+
+.. note::
+
+   The parameter of all these ioctls is a pointer to a
+   :ref:`v4l2_std_id <v4l2-std-id>` type (a standard set), *not* an
+   index into the standard enumeration. Drivers must implement all video
+   standard ioctls when the device has one or more video inputs or outputs.
+
+Special rules apply to devices such as USB cameras where the notion of
+video standards makes little sense. More generally for any capture or
+output device which is:
+
+-  incapable of capturing fields or frames at the nominal rate of the
+   video standard, or
+
+-  that does not support the video standard formats at all.
+
+Here the driver shall set the ``std`` field of struct
+:c:type:`v4l2_input` and struct
+:c:type:`v4l2_output` to zero and the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`,
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>`, :ref:`VIDIOC_QUERYSTD` and :ref:`VIDIOC_ENUMSTD` ioctls
+shall return the ``ENOTTY`` error code or the ``EINVAL`` error code.
+
+Applications can make use of the :ref:`input-capabilities` and
+:ref:`output-capabilities` flags to determine whether the video
+standard ioctls can be used with the given input or output.

+Streaming Parameters
+********************
+
+Streaming parameters are intended to optimize the video capture process
+as well as I/O. Presently applications can request a high quality
+capture mode with the :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl.
+
+The current video standard determines a nominal number of frames per
+second. If less than this number of frames is to be captured or output,
+applications can request frame skipping or duplicating on the driver
+side. This is especially useful when using the
+:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are
+not augmented by timestamps or sequence counters, and to avoid
+unnecessary data copying.
+
+Finally these ioctls can be used to determine the number of buffers used
+internally by a driver in read/write mode. For implications see the
+section discussing the :ref:`read() <func-read>` function.
+
+To get and set the streaming parameters applications call the
+:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take
+a pointer to a struct :c:type:`v4l2_streamparm`, which
+contains a union holding separate parameters for input and output
+devices.
+
+These ioctls are optional, drivers need not implement them. If so, they
+return the ``EINVAL`` error code.

+
+Media Bus Pixel Codes
+---------------------
+
+The media bus pixel codes describe image formats as flowing over
+physical buses (both between separate physical components and inside
+SoC devices). This should not be confused with the V4L2 pixel formats
+that describe, using four character codes, image formats as stored in
+memory.
+
+While there is a relationship between image formats on buses and image
+formats in memory (a raw Bayer image won't be magically converted to
+JPEG just by storing it to memory), there is no one-to-one
+correspondence between them.
+
+The media bus pixel codes document parallel formats. Should the pixel data be
+transported over a serial bus, the media bus pixel code that describes a
+parallel format that transfers a sample on a single clock cycle is used. For
+instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used
+on parallel busses for transferring an 8 bits per sample BGR data, whereas on
+serial busses the data in this format is only referred to using
+MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single
+way to transport that format on the serial busses.
+
+Packed RGB Formats
+^^^^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. Possible values are RGB and BGR.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. Common values are 555 and 565.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO). A "C" prefix is used for
+   component-wise padding in the most high order bits (CPADHI) or low
+   order bits (CPADLO) of each separate component.
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format where pixels are encoded as 5-bits red, 5-bits
+green and 5-bit blue values padded on the high bit, transferred as 2
+8-bit samples per pixel with the most significant bits (padding, red and
+half of the green value) transferred first will be named
+``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``.
+
+The following tables list existing packed RGB formats.
+
+.. HACK: ideally, we would be using adjustbox here. However, Sphinx
+.. is a very bad behaviored guy: if the table has more than 30 cols,
+.. it switches to long table, and there's no way to override it.

+On LVDS buses, usually each sample is transferred serialized in seven
+time slots per pixel clock, on three (18-bit) or four (24-bit)
+differential data pairs at the same time. The remaining bits are used
+for control signals as defined by SPWG/PSWG/VESA or JEIDA standards. The

+Bayer Formats
+^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. The possible values are shown in :ref:`bayer-patterns`.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The compression (optional). If the pixel components are ALAW- or
+   DPCM-compressed, a mention of the compression scheme and the number
+   of bits per compressed pixel component.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format with uncompressed 10-bit Bayer components
+arranged in a red, green, green, blue pattern transferred as 2 8-bit
+samples per pixel with the least significant bits transferred first will
+be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``.

+Packed YUV Formats
+^^^^^^^^^^^^^^^^^^
+
+Those data formats transfer pixel data as (possibly downsampled) Y, U
+and V components. Some formats include dummy bits in some of their
+samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma)
+formats. One cannot rely on the values of these dummy bits as those are
+undefined.
+
+The format code is made of the following information.
+
+-  The Y, U and V components order code, as transferred on the bus.
+   Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
+   dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC
+   formats.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   0.5 (encoded as 0_5; in this case two pixels are transferred per bus
+   sample), 1, 1.5 (encoded as 1_5) and 2.
+
+-  The bus width. When the bus width is larger than the number of bits
+   per pixel component, several components are packed in a single bus
+   sample. The components are ordered as specified by the order code,
+   with components on the left of the code transferred in the high order
+   bits. Common values are 8 and 16.
+
+For instance, a format where pixels are encoded as 8-bit YUV values
+downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in
+the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``.
+
+:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and
+describes the organization of each pixel data in each sample. When a
+format pattern is split across multiple samples each of the samples in
+the pattern is described.
+
+The role of each bit transferred over the bus is identified by one of
+the following codes.
+
+-  y\ :sub:`x` for luma component bit number x
+
+-  u\ :sub:`x` for blue chroma component bit number x
+
+-  v\ :sub:`x` for red chroma component bit number x
+
+-  a\ :sub:`x` for alpha component bit number x
+
+- for non-available bits (for positions higher than the bus width)
+
+-  d for dummy bits

+HSV/HSL Formats
+^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as RGB values in a
+cylindrical-coordinate system using Hue-Saturation-Value or
+Hue-Saturation-Lightness components. The format code is made of the
+following information.
+
+-  The hue, saturation, value or lightness and optional alpha components
+   order code, as encoded in a pixel sample. The only currently
+   supported value is AHSV.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. The only currently supported value
+   is 8888.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. The only currently
+   supported value is 1.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+The following table lists existing HSV/HSL formats.

+JPEG Compressed Formats
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Those data formats consist of an ordered sequence of 8-bit bytes
+obtained from JPEG compression process. Additionally to the ``_JPEG``
+postfix the format code is made of the following information.
+
+-  The number of bus samples per entropy encoded byte.
+
+-  The bus width.
+
+For instance, for a JPEG baseline process and an 8-bit bus width the
+format will be named ``MEDIA_BUS_FMT_JPEG_1X8``.
+
+The following table lists existing JPEG compressed formats.

+*********************
+Tuners and Modulators
+*********************
+
+
+Tuners
+======
+
+Video input devices can have one or more tuners demodulating a RF
+signal. Each tuner is associated with one or more video inputs,
+depending on the number of RF connectors on the tuner. The ``type``
+field of the respective struct :c:type:`v4l2_input`
+returned by the :ref:`VIDIOC_ENUMINPUT` ioctl is
+set to ``V4L2_INPUT_TYPE_TUNER`` and its ``tuner`` field contains the
+index number of the tuner.
+
+Radio input devices have exactly one tuner with index zero, no video
+inputs.
+
+To query and change tuner properties applications use the
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` ioctls, respectively. The
+struct :c:type:`v4l2_tuner` returned by :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>`
+also contains signal status information applicable when the tuner of the
+current video or radio input is queried.
+
+.. note::
+
+   :ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` does not switch the
+   current tuner, when there is more than one. The tuner is solely
+   determined by the current video input. Drivers must support both ioctls
+   and set the ``V4L2_CAP_TUNER`` flag in the struct :c:type:`v4l2_capability`
+   returned by the :ref:`VIDIOC_QUERYCAP` ioctl when the
+   device has one or more tuners.
+
+
+Modulators
+==========
+
+Video output devices can have one or more modulators, that modulate a
+video signal for radiation or connection to the antenna input of a TV
+set or video recorder. Each modulator is associated with one or more
+video outputs, depending on the number of RF connectors on the
+modulator. The ``type`` field of the respective struct
+:c:type:`v4l2_output` returned by the
+:ref:`VIDIOC_ENUMOUTPUT` ioctl is set to
+``V4L2_OUTPUT_TYPE_MODULATOR`` and its ``modulator`` field contains the
+index number of the modulator.
+
+Radio output devices have exactly one modulator with index zero, no
+video outputs.
+
+A video or radio device cannot support both a tuner and a modulator. Two
+separate device nodes will have to be used for such hardware, one that
+supports the tuner functionality and one that supports the modulator
+functionality. The reason is a limitation with the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl where you
+cannot specify whether the frequency is for a tuner or a modulator.
+
+To query and change modulator properties applications use the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` and
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Note that
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` does not switch the current modulator, when there
+is more than one at all. The modulator is solely determined by the
+current video output. Drivers must support both ioctls and set the
+``V4L2_CAP_MODULATOR`` flag in the struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl when the device has
+one or more modulators.
+
+
+Radio Frequency
+===============
+
+To get and set the tuner or modulator radio frequency applications use
+the :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl which both take
+a pointer to a struct :c:type:`v4l2_frequency`. These
+ioctls are used for TV and radio devices alike. Drivers must support
+both ioctls when the tuner or modulator ioctls are supported, or when
+the device is a radio device.

+*****************************
+Streaming I/O (User Pointers)
+*****************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. If the
+particular user pointer method (not only memory mapping) is supported
+must be determined by calling the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_USERPTR``.
+
+This I/O method combines advantages of the read/write and memory mapping
+methods. Buffers (planes) are allocated by the application itself, and
+can reside for example in virtual or shared memory. Only pointers to
+data are exchanged, these pointers and meta-information are passed in
+struct :c:type:`v4l2_buffer` (or in struct
+:c:type:`v4l2_plane` in the multi-planar API case). The
+driver must be switched into user pointer I/O mode by calling the
+:ref:`VIDIOC_REQBUFS` with the desired buffer type.
+No buffers (planes) are allocated beforehand, consequently they are not
+indexed and cannot be queried like mapped buffers with the
+:ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>` ioctl.
+
+Example: Initiating streaming I/O with user pointers
+====================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset (&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_USERPTR;
+
+    if (ioctl (fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf ("Video capturing or user pointer streaming is not supported\\n");
+	else
+	    perror ("VIDIOC_REQBUFS");
+
+	exit (EXIT_FAILURE);
+    }
+
+Buffer (plane) addresses and sizes are passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. Although buffers are commonly
+cycled, applications can pass different addresses and sizes at each
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call. If required by the hardware the
+driver swaps memory pages within physical memory to create a continuous
+area of memory. This happens transparently to the application in the
+virtual memory subsystem of the kernel. When buffer pages have been
+swapped out to disk they are brought back and finally locked in physical
+memory for DMA. [#f1]_
+
+Filled or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+memory pages at any time between the completion of the DMA and this
+ioctl. The memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS`, or when the device is closed.
+Applications must take care not to free buffers without dequeuing.
+Firstly, the buffers remain locked for longer, wasting physical memory.
+Secondly the driver will not be notified when the memory is returned to
+the application's free list and subsequently reused for other purposes,
+possibly completing the requested DMA and overwriting valuable data.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The :ref:`select()
+<func-select>` or :ref:`poll() <func-poll>` function are always
+available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctl.
+
+.. note::
+
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing user pointer I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   We expect that frequently used buffers are typically not swapped out.
+   Anyway, the process of swapping, locking or generating scatter-gather
+   lists may be time consuming. The delay can be masked by the depth of
+   the incoming buffer queue, and perhaps by maintaining caches assuming
+   a buffer will be soon enqueued again. On the other hand, to optimize
+   memory usage drivers can limit the number of buffers locked in
+   advance and recycle the most recently used buffers first. Of course,
+   the pages of empty buffers in the incoming queue need not be saved to
+   disk. Output buffers must be saved on the incoming and outgoing queue
+   because an application may share them with other processes.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+Video Grabber example using libv4l
+**********************************
+
+This program demonstrates how to grab V4L2 images in ppm format by using
+libv4l handlers. The advantage is that this grabber can potentially work
+with any V4L2 driver.

+Video Inputs and Outputs
+************************
+
+Video inputs and outputs are physical connectors of a device. These can
+be for example: RF connectors (antenna/cable), CVBS a.k.a. Composite
+Video, S-Video and RGB connectors. Camera sensors are also considered to
+be a video input. Video and VBI capture devices have inputs. Video and
+VBI output devices have outputs, at least one each. Radio devices have
+no video inputs or outputs.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctl, respectively. The
+struct :c:type:`v4l2_input` returned by the
+:ref:`VIDIOC_ENUMINPUT` ioctl also contains signal
+status information applicable when the current video input is queried.
+
+The :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` ioctls return the index of
+the current video input or output. To select a different input or output
+applications call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` ioctls. Drivers must
+implement all the input ioctls when the device has one or more inputs,
+all the output ioctls when the device has one or more outputs.
+
+Example: Information about the current video input
+==================================================
+

+VIDIOC_CREATE_BUFS - Create buffers for Memory Mapped or User Pointer or DMA Buffer I/O
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_CREATE_BUFS, struct v4l2_create_buffers *argp )
+    :name: VIDIOC_CREATE_BUFS
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_create_buffers`.
+
+
+Description
+===========
+
+This ioctl is used to create buffers for :ref:`memory mapped <mmap>`
+or :ref:`user pointer <userp>` or :ref:`DMA buffer <dmabuf>` I/O. It
+can be used as an alternative or in addition to the
+:ref:`VIDIOC_REQBUFS` ioctl, when a tighter control
+over buffers is required. This ioctl can be called multiple times to
+create buffers of different sizes.
+
+To allocate the device buffers applications must initialize the relevant
+fields of the struct :c:type:`v4l2_create_buffers` structure. The
+``count`` field must be set to the number of requested buffers, the
+``memory`` field specifies the requested I/O method and the ``reserved``
+array must be zeroed.
+
+The ``format`` field specifies the image format that the buffers must be
+able to handle. The application has to fill in this struct
+:c:type:`v4l2_format`. Usually this will be done using the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctls to ensure that the
+requested format is supported by the driver. Based on the format's
+``type`` field the requested buffer size (for single-planar) or plane
+sizes (for multi-planar formats) will be used for the allocated buffers.
+The driver may return an error if the size(s) are not supported by the
+hardware (usually because they are too small).
+
+The buffers created by this ioctl will have as minimum size the size
+defined by the ``format.pix.sizeimage`` field (or the corresponding
+fields for other format types). Usually if the ``format.pix.sizeimage``
+field is less than the minimum required for the given format, then an
+error will be returned since drivers will typically not allow this. If
+it is larger, then the value will be used as-is. In other words, the
+driver may reject the requested size, but if it is accepted the driver
+will use it unchanged.
+
+When the ioctl is called with a pointer to this structure the driver
+will attempt to allocate up to the requested number of buffers and store
+the actual number allocated and the starting index in the ``count`` and
+the ``index`` fields respectively. On return ``count`` can be smaller
+than the number requested.

+	:ref:`VIDIOC_CREATE_BUFS` will set ``index`` to the current number of
+	created buffers, and it will check the validity of ``memory`` and
+	``format.type``. If those are invalid -1 is returned and errno is
+	set to ``EINVAL`` error code, otherwise :ref:`VIDIOC_CREATE_BUFS` returns
+	0. It will never set errno to ``EBUSY`` error code in this particular
+	case.

+    * - struct :c:type:`v4l2_format`
+      - ``format``
+      - Filled in by the application, preserved by the driver.
+    * - __u32
+      - ``capabilities``
+      - Set by the driver. If 0, then the driver doesn't support
+        capabilities. In that case all you know is that the driver is
+	guaranteed to support ``V4L2_MEMORY_MMAP`` and *might* support
+	other :c:type:`v4l2_memory` types. It will not support any other
+	capabilities. See :ref:`here <v4l2-buf-capabilities>` for a list of the
+	capabilities.
+
+	If you want to just query the capabilities without making any
+	other changes, then set ``count`` to 0, ``memory`` to
+	``V4L2_MEMORY_MMAP`` and ``format.type`` to the buffer type.
+    * - __u32
+      - ``reserved``\ [7]
+      - A place holder for future extensions. Drivers and applications
+	must set the array to zero.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENOMEM
+    No memory to allocate buffers for :ref:`memory mapped <mmap>` I/O.
+
+EINVAL
+    The buffer type (``format.type`` field), requested I/O method
+    (``memory``) or format (``format`` field) is not valid.

+Synopsis

+    :name: VIDIOC_CROPCAP
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_cropcap`.
+
+
+Description
+===========
+
+Applications use this function to query the cropping limits, the pixel
+aspect of images and to calculate scale factors. They set the ``type``
+field of a v4l2_cropcap structure to the respective buffer (stream)
+type and call the :ref:`VIDIOC_CROPCAP` ioctl with a pointer to this
+structure. Drivers fill the rest of the structure. The results are
+constant except when switching the video standard. Remember this switch
+can occur implicit when switching the video input or output.
+
+This ioctl must be implemented for video capture or output devices that
+support cropping and/or scaling and/or have non-square pixels, and for
+overlay devices.

+
+    * - __u32
+      - ``type``
+      - Type of the data stream, set by the application. Only these types
+	are valid here: ``V4L2_BUF_TYPE_VIDEO_CAPTURE``, ``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``,
+	``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE`` and
+	``V4L2_BUF_TYPE_VIDEO_OVERLAY``. See :c:type:`v4l2_buf_type` and the note below.
+    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
+      - ``bounds``
+      - Defines the window within capturing or output is possible, this
+	may exclude for example the horizontal and vertical blanking
+	areas. The cropping rectangle cannot exceed these limits. Width
+	and height are defined in pixels, the driver writer is free to
+	choose origin and units of the coordinate system in the analog
+	domain.
+    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
+      - ``defrect``
+      - Default cropping rectangle, it shall cover the "whole picture".
+	Assuming pixel aspect 1/1 this could be for example a 640 × 480
+	rectangle for NTSC, a 768 × 576 rectangle for PAL and SECAM
+	centered over the active picture area. The same co-ordinate system
+	as for ``bounds`` is used.
+    * - struct :c:type:`v4l2_fract`
+      - ``pixelaspect``
+      - This is the pixel aspect (y / x) when no scaling is applied, the
+	ratio of the actual sampling frequency and the frequency required
+	to get square pixels.
+
+	When cropping coordinates refer to square pixels, the driver sets
+	``pixelaspect`` to 1/1. Other common values are 54/59 for PAL and
+	SECAM, 11/10 for NTSC sampled according to [:ref:`itu601`].
+
+.. note::
+   Unfortunately in the case of multiplanar buffer types
+   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
+   this API was messed up with regards to how the :c:type:`v4l2_cropcap` ``type`` field
+   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
+   other drivers only accepted a non-multiplanar buffer type (i.e. without the
+   ``_MPLANE`` at the end).
+
+   Starting with kernel 4.13 both variations are allowed.

+Synopsis

+

+    :name: VIDIOC_DBG_G_CHIP_INFO
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_dbg_chip_info`.
+
+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes this ioctl allows test applications to
+query the driver about the chips present on the TV card. Regular
+applications must not use it. When you found a chip specific bug, please
+contact the linux-media mailing list
+(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
+so it can be fixed.
+
+Additionally the Linux kernel must be compiled with the
+``CONFIG_VIDEO_ADV_DEBUG`` option to enable this ioctl.
+
+To query the driver applications must initialize the ``match.type`` and
+``match.addr`` or ``match.name`` fields of a struct
+:c:type:`v4l2_dbg_chip_info` and call
+:ref:`VIDIOC_DBG_G_CHIP_INFO` with a pointer to this structure. On success
+the driver stores information about the selected chip in the ``name``
+and ``flags`` fields.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth bridge 'chip' on the TV card. You can enumerate all
+chips by starting at zero and incrementing ``match.addr`` by one until
+:ref:`VIDIOC_DBG_G_CHIP_INFO` fails with an ``EINVAL`` error code. The number
+zero always selects the bridge chip itself, e. g. the chip connected to
+the PCI or USB bus. Non-zero numbers identify specific parts of the
+bridge chip such as an AC97 register block.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device. This allows you to enumerate over all
+sub-devices.
+
+On success, the ``name`` field will contain a chip name and the
+``flags`` field will contain ``V4L2_CHIP_FL_READABLE`` if the driver
+supports reading registers from the device or ``V4L2_CHIP_FL_WRITABLE``
+if the driver supports writing registers to the device.
+
+We recommended the v4l2-dbg utility over calling this ioctl directly. It
+is available from the LinuxTV v4l-dvb repository; see
+`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access
+instructions.

+    :name: VIDIOC_DBG_S_REGISTER
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_dbg_register`.
+
+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes these ioctls allow test applications to
+access hardware registers directly. Regular applications must not use
+them.
+
+Since writing or even reading registers can jeopardize the system
+security, its stability and damage the hardware, both ioctls require
+superuser privileges. Additionally the Linux kernel must be compiled
+with the ``CONFIG_VIDEO_ADV_DEBUG`` option to enable these ioctls.
+
+To write a register applications must initialize all fields of a struct
+:c:type:`v4l2_dbg_register` except for ``size`` and
+call ``VIDIOC_DBG_S_REGISTER`` with a pointer to this structure. The
+``match.type`` and ``match.addr`` or ``match.name`` fields select a chip
+on the TV card, the ``reg`` field specifies a register number and the
+``val`` field the value to be written into the register.
+
+To read a register applications must initialize the ``match.type``,
+``match.addr`` or ``match.name`` and ``reg`` fields, and call
+``VIDIOC_DBG_G_REGISTER`` with a pointer to this structure. On success
+the driver stores the register value in the ``val`` field and the size
+(in bytes) of the value in ``size``.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth non-sub-device chip on the TV card. The number zero
+always selects the host chip, e. g. the chip connected to the PCI or USB
+bus. You can find out which chips are present with the
+:ref:`VIDIOC_DBG_G_CHIP_INFO` ioctl.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device.
+
+These ioctls are optional, not all drivers may support them. However
+when a driver supports these ioctls it must also support
+:ref:`VIDIOC_DBG_G_CHIP_INFO`. Conversely
+it may support ``VIDIOC_DBG_G_CHIP_INFO`` but not these ioctls.
+
+``VIDIOC_DBG_G_REGISTER`` and ``VIDIOC_DBG_S_REGISTER`` were introduced
+in Linux 2.6.21, but their API was changed to the one described here in
+kernel 2.6.29.
+
+We recommended the v4l2-dbg utility over calling these ioctls directly.
+It is available from the LinuxTV v4l-dvb repository; see
+`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access
+instructions.

+``argp``
+    pointer to struct :c:type:`v4l2_decoder_cmd`.
+
+
+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) decoder.
+``VIDIOC_DECODER_CMD`` sends a command to the decoder,
+``VIDIOC_TRY_DECODER_CMD`` can be used to try a command without actually
+executing it. To send a command applications must initialize all fields
+of a struct :c:type:`v4l2_decoder_cmd` and call
+``VIDIOC_DECODER_CMD`` or ``VIDIOC_TRY_DECODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. Some commands use the
+``flags`` field for additional information.
+
+A :ref:`write() <func-write>` or :ref:`VIDIOC_STREAMON`
+call sends an implicit START command to the decoder if it has not been
+started yet. Applies to both queues of mem2mem decoders.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP
+command to the decoder, and all buffered data is discarded. Applies to both
+queues of mem2mem decoders.
+
+In principle, these ioctls are optional, not all drivers may support them. They were
+introduced in Linux 3.3. They are, however, mandatory for stateful mem2mem decoders
+(as further documented in :ref:`decoder`).

+      - __s32
+      - ``speed``
+      - Playback speed and direction. The playback speed is defined as
+	``speed``/1000 of the normal speed. So 1000 is normal playback.
+	Negative numbers denote reverse playback, so -1000 does reverse
+	playback at normal speed. Speeds -1, 0 and 1 have special
+	meanings: speed 0 is shorthand for 1000 (normal playback). A speed
+	of 1 steps just one frame forward, a speed of -1 steps just one
+	frame back.
+    * -
+      - __u32
+      - ``format``
+      - Format restrictions. This field is set by the driver, not the
+	application. Possible values are ``V4L2_DEC_START_FMT_NONE`` if
+	there are no format restrictions or ``V4L2_DEC_START_FMT_GOP`` if
+	the decoder operates on full GOPs (*Group Of Pictures*). This is
+	usually the case for reverse playback: the decoder needs full
+	GOPs, which it can then play in reverse order. So to implement
+	reverse playback the application must feed the decoder the last
+	GOP in the video file, then the GOP before that, etc. etc.
+    * - struct

+      - __u32
+      - ``data``\ [16]

+
+    * - ``V4L2_DEC_CMD_START``
+      - 0
+      - Start the decoder. When the decoder is already running or paused,
+	this command will just change the playback speed. That means that
+	calling ``V4L2_DEC_CMD_START`` when the decoder was paused will
+	*not* resume the decoder. You have to explicitly call
+	``V4L2_DEC_CMD_RESUME`` for that. This command has one flag:
+	``V4L2_DEC_CMD_START_MUTE_AUDIO``. If set, then audio will be
+	muted when playing back at a non-standard speed.
+
+	For a device implementing the :ref:`decoder`, once the drain sequence
+	is initiated with the ``V4L2_DEC_CMD_STOP`` command, it must be driven
+	to completion before this command can be invoked.  Any attempt to
+	invoke the command while the drain sequence is in progress will trigger
+	an ``EBUSY`` error code.  The command may be also used to restart the
+	decoder in case of an implicit stop initiated by the decoder itself,
+	without the ``V4L2_DEC_CMD_STOP`` being called explicitly. See
+	:ref:`decoder` for more details.
+    * - ``V4L2_DEC_CMD_STOP``
+      - 1
+      - Stop the decoder. When the decoder is already stopped, this
+	command does nothing. This command has two flags: if
+	``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set
+	the picture to black after it stopped decoding. Otherwise the last
+	image will repeat. If
+	``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops
+	immediately (ignoring the ``pts`` value), otherwise it will keep
+	decoding until timestamp >= pts or until the last of the pending
+	data from its internal buffers was decoded.
+
+	For a device implementing the :ref:`decoder`, the command will initiate
+	the drain sequence as documented in :ref:`decoder`.  No flags or other
+	arguments are accepted in this case. Any attempt to invoke the command
+	again before the sequence completes will trigger an ``EBUSY`` error
+	code.
+    * - ``V4L2_DEC_CMD_PAUSE``
+      - 2
+      - Pause the decoder. When the decoder has not been started yet, the
+	driver will return an ``EPERM`` error code. When the decoder is
+	already paused, this command does nothing. This command has one
+	flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the
+	decoder output to black when paused.
+    * - ``V4L2_DEC_CMD_RESUME``
+      - 3
+      - Resume decoding after a PAUSE command. When the decoder has not
+	been started yet, the driver will return an ``EPERM`` error code. When
+	the decoder is already running, this command does nothing. No
+	flags are defined for this command.
+    * - ``V4L2_DEC_CMD_FLUSH``
+      - 4
+      - Flush any held capture buffers. Only valid for stateless decoders.
+	This command is typically used when the application reached the
+	end of the stream and the last output buffer had the
+	``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag set. This would prevent
+	dequeueing the capture buffer containing the last decoded frame.
+	So this command can be used to explicitly flush that final decoded
+	frame. This command does nothing if there are no held capture buffers.
+
+Return Value

+    * - ``V4L2_EVENT_FRAME_SYNC``
+      - 4
+      - Triggered immediately when the reception of a frame has begun.
+	This event has a struct

+	associated with it.
+
+	If the hardware needs to be stopped in the case of a buffer
+	underrun it might not be able to generate this event. In such

+	index (when used with a subdevice node) from which you want to
+	receive events.
+
+	This event has a struct

+
+
+Description
+===========
+
+To query the capabilities of the DV receiver/transmitter applications
+initialize the ``pad`` field to 0, zero the reserved array of struct
+:c:type:`v4l2_dv_timings_cap` and call the
+``VIDIOC_DV_TIMINGS_CAP`` ioctl on a video node and the driver will fill
+in the structure.
+
+.. note::
+
+   Drivers may return different values after
+   switching the video input or output.
+
+When implemented by the driver DV capabilities of subdevices can be
+queried by calling the ``VIDIOC_SUBDEV_DV_TIMINGS_CAP`` ioctl directly
+on a subdevice node. The capabilities are specific to inputs (for DV
+receivers) or outputs (for DV transmitters), applications must specify
+the desired pad number in the struct
+:c:type:`v4l2_dv_timings_cap` ``pad`` field and
+zero the ``reserved`` array. Attempts to query capabilities on a pad
+that doesn't support them will return an ``EINVAL`` error code.

+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_encoder_cmd`.
+
+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) encoder.
+``VIDIOC_ENCODER_CMD`` sends a command to the encoder,
+``VIDIOC_TRY_ENCODER_CMD`` can be used to try a command without actually
+executing it.
+
+To send a command applications must initialize all fields of a struct
+:c:type:`v4l2_encoder_cmd` and call
+``VIDIOC_ENCODER_CMD`` or ``VIDIOC_TRY_ENCODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. The ``flags`` field is
+currently only used by the STOP command and contains one bit: If the
+``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag is set, encoding will continue
+until the end of the current *Group Of Pictures*, otherwise it will stop
+immediately.
+
+A :ref:`read() <func-read>` or :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+call sends an implicit START command to the encoder if it has not been
+started yet. After a STOP command, :ref:`read() <func-read>` calls will read
+the remaining data buffered by the driver. When the buffer is empty,
+:ref:`read() <func-read>` will return zero and the next :ref:`read() <func-read>`
+call will restart the encoder.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP to
+the encoder, and all buffered data is discarded.
+
+These ioctls are optional, not all drivers may support them. They were
+introduced in Linux 2.6.21.

+Description
+===========
+
+While some DV receivers or transmitters support a wide range of timings,
+others support only a limited number of timings. With this ioctl
+applications can enumerate a list of known supported timings. Call
+:ref:`VIDIOC_DV_TIMINGS_CAP` to check if it
+also supports other standards or even custom timings that are not in
+this list.
+
+To query the available timings, applications initialize the ``index``
+field, set the ``pad`` field to 0, zero the reserved array of struct
+:c:type:`v4l2_enum_dv_timings` and call the
+``VIDIOC_ENUM_DV_TIMINGS`` ioctl on a video node with a pointer to this
+structure. Drivers fill the rest of the structure or return an ``EINVAL``
+error code when the index is out of bounds. To enumerate all supported
+DV timings, applications shall begin at index zero, incrementing by one
+until the driver returns ``EINVAL``.
+
+.. note::
+
+   Drivers may enumerate a different set of DV timings after
+   switching the video input or output.
+
+When implemented by the driver DV timings of subdevices can be queried
+by calling the ``VIDIOC_SUBDEV_ENUM_DV_TIMINGS`` ioctl directly on a
+subdevice node. The DV timings are specific to inputs (for DV receivers)
+or outputs (for DV transmitters), applications must specify the desired
+pad number in the struct
+:c:type:`v4l2_enum_dv_timings` ``pad`` field.
+Attempts to enumerate timings on a pad that doesn't support them will
+return an ``EINVAL`` error code.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_fmtdesc`.
+
+
+Description
+===========
+
+To enumerate image formats applications initialize the ``type``, ``mbus_code``
+and ``index`` fields of struct :c:type:`v4l2_fmtdesc` and call
+the :ref:`VIDIOC_ENUM_FMT` ioctl with a pointer to this structure. Drivers
+fill the rest of the structure or return an ``EINVAL`` error code. All
+formats are enumerable by beginning at index zero and incrementing by
+one until ``EINVAL`` is returned. If applicable, drivers shall return
+formats in preference order, where preferred formats are returned before
+(that is, with lower ``index`` value) less-preferred formats.
+
+Depending on the ``V4L2_CAP_IO_MC`` :ref:`capability <device-capabilities>`,
+the ``mbus_code`` field is handled differently:
+
+1) ``V4L2_CAP_IO_MC`` is not set (also known as a 'video-node-centric' driver)
+
+   Applications shall initialize the ``mbus_code`` field to zero and drivers
+   shall ignore the value of the field.
+
+   Drivers shall enumerate all image formats.
+
+   .. note::
+
+      After switching the input or output the list of enumerated image
+      formats may be different.
+
+2) ``V4L2_CAP_IO_MC`` is set (also known as an 'MC-centric' driver)
+
+   If the ``mbus_code`` field is zero, then all image formats
+   shall be enumerated.
+
+   If the ``mbus_code`` field is initialized to a valid (non-zero)
+   :ref:`media bus format code <v4l2-mbus-pixelcode>`, then drivers
+   shall restrict enumeration to only the image formats that can produce
+   (for video output devices) or be produced from (for video capture
+   devices) that media bus code. If the ``mbus_code`` is unsupported by
+   the driver, then ``EINVAL`` shall be returned.
+
+   Regardless of the value of the ``mbus_code`` field, the enumerated image
+   formats shall not depend on the active configuration of the video device
+   or device pipeline.

+
+``argp``
+    Pointer to struct :c:type:`v4l2_frmivalenum`
+    that contains a pixel format and size and receives a frame interval.
+
+
+Description
+===========
+
+This ioctl allows applications to enumerate all frame intervals that the
+device supports for the given pixel format and frame size.
+
+The supported pixel formats and frame sizes can be obtained by using the
+:ref:`VIDIOC_ENUM_FMT` and
+:ref:`VIDIOC_ENUM_FRAMESIZES` functions.
+
+The return value and the content of the ``v4l2_frmivalenum.type`` field
+depend on the type of frame intervals the device supports. Here are the
+semantics of the function for the different cases:
+
+-  **Discrete:** The function returns success if the given index value
+   (zero-based) is valid. The application should increase the index by
+   one for each call until ``EINVAL`` is returned. The
+   `v4l2_frmivalenum.type` field is set to
+   `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the union only
+   the `discrete` member is valid.
+
+-  **Step-wise:** The function returns success if the given index value
+   is zero and ``EINVAL`` for any other index value. The
+   ``v4l2_frmivalenum.type`` field is set to
+   ``V4L2_FRMIVAL_TYPE_STEPWISE`` by the driver. Of the union only the
+   ``stepwise`` member is valid.
+
+-  **Continuous:** This is a special case of the step-wise type above.
+   The function returns success if the given index value is zero and
+   ``EINVAL`` for any other index value. The ``v4l2_frmivalenum.type``
+   field is set to ``V4L2_FRMIVAL_TYPE_CONTINUOUS`` by the driver. Of
+   the union only the ``stepwise`` member is valid and the ``step``
+   value is set to 1.
+
+When the application calls the function with index zero, it must check
+the ``type`` field to determine the type of frame interval enumeration
+the device supports. Only for the ``V4L2_FRMIVAL_TYPE_DISCRETE`` type
+does it make sense to increase the index value to receive more frame
+intervals.
+
+.. note::
+
+   The order in which the frame intervals are returned has no
+   special meaning. In particular does it not say anything about potential
+   default frame intervals.
+
+Applications can assume that the enumeration data does not change
+without any interaction from the application itself. This means that the
+enumeration data is consistent if the application does not perform any
+other ioctl calls while it runs the frame interval enumeration.
+
+.. note::
+
+   **Frame intervals and frame rates:** The V4L2 API uses frame
+   intervals instead of frame rates. Given the frame interval the frame
+   rate can be computed as follows:
+
+   ::
+
+       frame_rate = 1 / frame_interval

+===========
+
+Enumerates the frequency bands that a tuner or modulator supports. To do
+this applications initialize the ``tuner``, ``type`` and ``index``
+fields, and zero out the ``reserved`` array of a struct
+:c:type:`v4l2_frequency_band` and call the

+
+This ioctl is supported if the ``V4L2_TUNER_CAP_FREQ_BANDS`` capability
+of the corresponding tuner/modulator is set.

+===========
+
+To query the attributes of a video outputs applications initialize the
+``index`` field of struct :c:type:`v4l2_output` and call
+the :ref:`VIDIOC_ENUMOUTPUT` with a pointer to this structure.
+Drivers fill the rest of the structure or return an ``EINVAL`` error code
+when the index is out of bounds. To enumerate all outputs applications
+shall begin at index zero, incrementing by one until the driver returns
+``EINVAL``.

+	The LSB corresponds to audio output 0, the MSB to output 31. Any
+	number of bits can be set, or none.
+
+	When the driver does not enumerate audio outputs no bits must be
+	set. Applications shall not interpret this as lack of audio

+Description
+===========
+
+To query the attributes of a video standard, especially a custom (driver
+defined) one, applications initialize the ``index`` field of struct
+:c:type:`v4l2_standard` and call the :ref:`VIDIOC_ENUMSTD`
+ioctl with a pointer to this structure. Drivers fill the rest of the

+    * - :ref:`v4l2_std_id <v4l2-std-id>`
+      - ``id``
+      - The bits in this field identify the standard as one of the common
+	standards listed in :ref:`v4l2-std-id`, or if bits 32 to 63 are
+	set as custom standards. Multiple bits can be set if the hardware
+	does not distinguish between these standards, however separate
+	indices do not indicate the opposite. The ``id`` must be unique.
+	No other enumerated struct :c:type:`v4l2_standard` structure,
+	for this input or output anyway, can contain the same set of bits.

+VIDIOC_EXPBUF - Export a buffer as a DMABUF file descriptor.
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_EXPBUF, struct v4l2_exportbuffer *argp )
+    :name: VIDIOC_EXPBUF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the :ref:`memory mapping <mmap>` I/O
+method, therefore it is available only for ``V4L2_MEMORY_MMAP`` buffers.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the
+:ref:`VIDIOC_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct
+:c:type:`v4l2_exportbuffer`. The ``type`` field is
+set to the same buffer type as was previously used with struct
+:c:type:`v4l2_requestbuffers` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. For the multi-planar API, applications set the ``plane`` field to
+the index of the plane to be exported. Valid planes range from zero to
+the maximal number of valid planes for the currently active format. For
+the single-planar API, applications must set ``plane`` to zero.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported. All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`VIDIOC_EXPBUF` calls.
+
+After calling :ref:`VIDIOC_EXPBUF` the ``fd`` field will be set by a
+driver. This is a DMABUF file descriptor. The application may pass it to
+other DMABUF-aware devices. Refer to :ref:`DMABUF importing <dmabuf>`
+for details about importing DMABUF files into V4L2 nodes. It is
+recommended to close a DMABUF file when it is no longer used to allow
+the associated memory to be reclaimed.

+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_crop`.
+
+
+Description
+===========
+
+To query the cropping rectangle size and position applications set the
+``type`` field of a struct :c:type:`v4l2_crop` structure to the
+respective buffer (stream) type and call the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` ioctl
+with a pointer to this structure. The driver fills the rest of the
+structure or returns the ``EINVAL`` error code if cropping is not supported.
+
+To change the cropping rectangle applications initialize the ``type``
+and struct :c:type:`v4l2_rect` substructure named ``c`` of a
+v4l2_crop structure and call the :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl with a pointer
+to this structure.
+
+The driver first adjusts the requested dimensions against hardware
+limits, i. e. the bounds given by the capture/output window, and it
+rounds to the closest possible values of horizontal and vertical offset,
+width and height. In particular the driver must round the vertical
+offset of the cropping rectangle to frame lines modulo two, such that
+the field order cannot be confused.
+
+Second the driver adjusts the image size (the opposite rectangle of the
+scaling process, source or target depending on the data direction) to
+the closest size possible while maintaining the current horizontal and
+vertical scaling factor.
+
+Finally the driver programs the hardware with the actual cropping and
+image parameters. :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` is a write-only ioctl, it does not
+return the actual parameters. To query them applications must call
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_G_FMT`. When the
+parameters are unsuitable the application may modify the cropping or
+image parameters and repeat the cycle until satisfactory parameters have
+been negotiated.
+
+When cropping is not supported then no parameters are changed and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` returns the ``EINVAL`` error code.

+   this API was messed up with regards to how the :c:type:`v4l2_crop` ``type`` field
+   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
+   other drivers only accepted a non-multiplanar buffer type (i.e. without the

+

+    Pointer to struct :c:type:`v4l2_control`.
+
+
+Description
+===========
+
+To get the current value of a control applications initialize the ``id``
+field of a struct :c:type:`v4l2_control` and call the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` ioctl with a pointer to this structure. To change the
+value of a control applications initialize the ``id`` and ``value``
+fields of a struct :c:type:`v4l2_control` and call the
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctl.
+
+When the ``id`` is invalid drivers return an ``EINVAL`` error code. When the
+``value`` is out of bounds drivers can choose to take the closest valid
+value or return an ``ERANGE`` error code, whatever seems more appropriate.
+However, :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` is a write-only ioctl, it does not return the
+actual new value. If the ``value`` is inappropriate for the control
+(e.g. if it refers to an unsupported menu index of a menu control), then
+EINVAL error code is returned as well.
+
+These ioctls work only with user controls. For other control classes the
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` or
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` must be used.

+
+``argp``
+    Pointer to struct :c:type:`v4l2_dv_timings`.
+
+
+Description
+===========
+
+To set DV timings for the input or output, applications use the
+:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get the current timings,
+applications use the :ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. The detailed timing
+information is filled in using the structure struct
+:c:type:`v4l2_dv_timings`. These ioctls take a
+pointer to the struct :c:type:`v4l2_dv_timings`
+structure as argument. If the ioctl is not supported or the timing
+values are not correct, the driver returns ``EINVAL`` error code.
+
+Calling ``VIDIOC_SUBDEV_S_DV_TIMINGS`` on a subdev device node that has been
+registered in read-only mode is not allowed. An error is returned and the errno
+variable is set to ``-EPERM``.
+
+The ``linux/v4l2-dv-timings.h`` header can be used to get the timings of
+the formats in the :ref:`cea861` and :ref:`vesadmt` standards. If
+the current input or output does not support DV timings (e.g. if
+:ref:`VIDIOC_ENUMINPUT` does not set the
+``V4L2_IN_CAP_DV_TIMINGS`` flag), then ``ENODATA`` error code is returned.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    This ioctl is not supported, or the :ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>`
+    parameter was unsuitable.
+
+ENODATA
+    Digital video timings are not supported for this input or output.
+
+EBUSY
+    The device is busy and therefore can not change the timings.
+

+	vertical blanking intervals are reduced, allowing a higher
+	resolution over the same bandwidth. This is a read-only flag,
+	applications must not set this.
+    * - ``V4L2_DV_FL_CAN_REDUCE_FPS``
+      - CEA-861 specific: set for CEA-861 formats with a framerate that is
+	a multiple of six. These formats can be optionally played at 1 /
+	1.001 speed to be compatible with 60 Hz based standards such as
+	NTSC and PAL-M that use a framerate of 29.97 frames per second. If
+	the transmitter can't generate such frequencies, then the flag
+	will also be cleared. This is a read-only flag, applications must
+	not set this.
+    * - ``V4L2_DV_FL_REDUCED_FPS``
+      - CEA-861 specific: only valid for video transmitters or video
+        receivers that have the ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
+	set. This flag is cleared otherwise. It is also only valid for
+	formats with the ``V4L2_DV_FL_CAN_REDUCE_FPS`` flag set, for other
+	formats the flag will be cleared by the driver.
+
+	If the application sets this flag for a transmitter, then the
+	pixelclock used to set up the transmitter is divided by 1.001 to
+	make it compatible with NTSC framerates. If the transmitter can't
+	generate such frequencies, then the flag will be cleared.
+
+	If a video receiver detects that the format uses a reduced framerate,
+	then it will set this flag to signal this to the application.
+    * - ``V4L2_DV_FL_HALF_LINE``
+      - Specific to interlaced formats: if set, then the vertical
+	frontporch of field 1 (aka the odd field) is really one half-line
+	longer and the vertical backporch of field 2 (aka the even field)
+	is really one half-line shorter, so each field has exactly the
+	same number of half-lines. Whether half-lines can be detected or
+	used depends on the hardware.
+    * - ``V4L2_DV_FL_IS_CE_VIDEO``
+      - If set, then this is a Consumer Electronics (CE) video format.
+	Such formats differ from other formats (commonly called IT
+	formats) in that if R'G'B' encoding is used then by default the
+	R'G'B' values use limited range (i.e. 16-235) as opposed to full
+	range (i.e. 0-255). All formats defined in CEA-861 except for the
+	640x480p59.94 format are CE formats.
+    * - ``V4L2_DV_FL_FIRST_FIELD_EXTRA_LINE``
+      - Some formats like SMPTE-125M have an interlaced signal with a odd
+	total height. For these formats, if this flag is set, the first
+	field has the extra line. Else, it is the second field.
+    * - ``V4L2_DV_FL_HAS_PICTURE_ASPECT``
+      - If set, then the picture_aspect field is valid. Otherwise assume that
+        the pixels are square, so the picture aspect ratio is the same as the
+	width to height ratio.
+    * - ``V4L2_DV_FL_HAS_CEA861_VIC``
+      - If set, then the cea861_vic field is valid and contains the Video
+        Identification Code as per the CEA-861 standard.
+    * - ``V4L2_DV_FL_HAS_HDMI_VIC``
+      - If set, then the hdmi_vic field is valid and contains the Video
+        Identification Code as per the HDMI standard (HDMI Vendor Specific
+	InfoFrame).
+    * - ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
+      - CEA-861 specific: only valid for video receivers, the flag is
+        cleared by transmitters.
+        If set, then the hardware can detect the difference between
+	regular framerates and framerates reduced by 1000/1001. E.g.:
+	60 vs 59.94 Hz, 30 vs 29.97 Hz or 24 vs 23.976 Hz.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+   Pointer to struct :c:type:`v4l2_edid`.
+
+
+Description
+===========
+
+These ioctls can be used to get or set an EDID associated with an input
+from a receiver or an output of a transmitter device. They can be used
+with subdevice nodes (/dev/v4l-subdevX) or with video nodes
+(/dev/videoX).
+
+When used with video nodes the ``pad`` field represents the input (for
+video capture devices) or output (for video output devices) index as is
+returned by :ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` respectively. When used
+with subdevice nodes the ``pad`` field represents the input or output
+pad of the subdevice. If there is no EDID support for the given ``pad``
+value, then the ``EINVAL`` error code will be returned.
+
+To get the EDID data the application has to fill in the ``pad``,
+``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
+array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
+``start_block`` and of size ``blocks`` will be placed in the memory
+``edid`` points to. The ``edid`` pointer must point to memory at least
+``blocks`` * 128 bytes large (the size of one block is 128 bytes).
+
+If there are fewer blocks than specified, then the driver will set
+``blocks`` to the actual number of blocks. If there are no EDID blocks
+available at all, then the error code ``ENODATA`` is set.
+
+If blocks have to be retrieved from the sink, then this call will block
+until they have been read.
+
+If ``start_block`` and ``blocks`` are both set to 0 when
+:ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
+total number of available EDID blocks and it will return 0 without
+copying any data. This is an easy way to discover how many EDID blocks
+there are.
+
+.. note::
+
+   If there are no EDID blocks available at all, then
+   the driver will set ``blocks`` to 0 and it returns 0.
+
+To set the EDID blocks of a receiver the application has to fill in the
+``pad``, ``blocks`` and ``edid`` fields, set ``start_block`` to 0 and
+zero the ``reserved`` array. It is not possible to set part of an EDID,
+it is always all or nothing. Setting the EDID data is only valid for
+receivers as it makes no sense for a transmitter.
+
+The driver assumes that the full EDID is passed in. If there are more

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_enc_idx`.
+
+
+Description
+===========
+
+The :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` ioctl provides meta data about a compressed
+video stream the same or another application currently reads from the
+driver, which is useful for random access into the stream without
+decoding it.
+
+To read the data applications must call :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` with a
+pointer to a struct :c:type:`v4l2_enc_idx`. On success
+the driver fills the ``entry`` array, stores the number of elements
+written in the ``entries`` field, and initializes the ``entries_cap``
+field.
+
+Each element of the ``entry`` array contains meta data about one
+picture. A :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` call reads up to
+``V4L2_ENC_IDX_ENTRIES`` entries from a driver buffer, which can hold up
+to ``entries_cap`` entries. This number can be lower or higher than
+``V4L2_ENC_IDX_ENTRIES``, but not zero. When the application fails to
+read the meta data in time the oldest entries will be lost. When the
+buffer is empty or no capturing/encoding is in progress, ``entries``
+will be zero.
+
+Currently this ioctl is only defined for MPEG-2 program streams and
+video elementary streams.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_ext_controls`.
+
+
+Description
+===========
+
+These ioctls allow the caller to get or set multiple controls
+atomically. Control IDs are grouped into control classes (see
+:ref:`ctrl-class`) and all controls in the control array must belong
+to the same control class.
+
+Applications must always fill in the ``count``, ``which``, ``controls``
+and ``reserved`` fields of struct
+:c:type:`v4l2_ext_controls`, and initialize the
+struct :c:type:`v4l2_ext_control` array pointed to
+by the ``controls`` fields.
+
+To get the current value of a set of controls applications initialize
+the ``id``, ``size`` and ``reserved2`` fields of each struct
+:c:type:`v4l2_ext_control` and call the
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. String controls controls must also set the
+``string`` field. Controls of compound types
+(``V4L2_CTRL_FLAG_HAS_PAYLOAD`` is set) must set the ``ptr`` field.
+
+If the ``size`` is too small to receive the control result (only
+relevant for pointer-type controls like strings), then the driver will
+set ``size`` to a valid value and return an ``ENOSPC`` error code. You
+should re-allocate the memory to this new size and try again. For the
+string type it is possible that the same issue occurs again if the
+string has grown in the meantime. It is recommended to call
+:ref:`VIDIOC_QUERYCTRL` first and use
+``maximum``\ +1 as the new ``size`` value. It is guaranteed that that is
+sufficient memory.
+
+N-dimensional arrays are set and retrieved row-by-row. You cannot set a
+partial array, all elements have to be set or retrieved. The total size
+is calculated as ``elems`` * ``elem_size``. These values can be obtained
+by calling :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>`.
+
+To change the value of a set of controls applications initialize the
+``id``, ``size``, ``reserved2`` and ``value/value64/string/ptr`` fields
+of each struct :c:type:`v4l2_ext_control` and call
+the :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. The controls will only be set if *all*
+control values are valid.
+
+To check if a set of controls have correct values applications
+initialize the ``id``, ``size``, ``reserved2`` and
+``value/value64/string/ptr`` fields of each struct
+:c:type:`v4l2_ext_control` and call the
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. It is up to the driver whether wrong
+values are automatically adjusted to a valid value or if an error is
+returned.
+
+When the ``id`` or ``which`` is invalid drivers return an ``EINVAL`` error
+code. When the value is out of bounds drivers can choose to take the
+closest valid value or return an ``ERANGE`` error code, whatever seems more
+appropriate. In the first case the new value is set in struct
+:c:type:`v4l2_ext_control`. If the new control value
+is inappropriate (e.g. the given menu index is not supported by the menu
+control), then this will also result in an ``EINVAL`` error code error.
+
+If ``request_fd`` is set to a not-yet-queued :ref:`request <media-request-api>`
+file descriptor and ``which`` is set to ``V4L2_CTRL_WHICH_REQUEST_VAL``,
+then the controls are not applied immediately when calling
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, but instead are applied by
+the driver for the buffer associated with the same request.
+If the device does not support requests, then ``EACCES`` will be returned.
+If requests are supported but an invalid request file descriptor is given,
+then ``EINVAL`` will be returned.
+
+An attempt to call :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
+request that has already been queued will result in an ``EBUSY`` error.
+
+If ``request_fd`` is specified and ``which`` is set to
+``V4L2_CTRL_WHICH_REQUEST_VAL`` during a call to
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then it will return the
+values of the controls at the time of request completion.
+If the request is not yet completed, then this will result in an
+``EACCES`` error.
+
+The driver will only set/get these controls if all control values are
+correct. This prevents the situation where only some of the controls
+were set/get. Only low-level errors (e. g. a failed i2c command) can
+still cause this situation.

+	the controls can belong to any control class. Whether drivers
+	support this can be tested by setting ``ctrl_class`` to 0 and

+	a request. In the latter case the ``request_fd`` field contains the
+	file descriptor of the request that should be used. If the device
+	does not support requests, then ``EACCES`` will be returned.
+
+	.. note::
+
+	   When using ``V4L2_CTRL_WHICH_DEF_VAL`` be aware that you can only
+	   get the default value of the control, you cannot set or try it.
+
+	For backwards compatibility you can also use a control class here
+	(see :ref:`ctrl-class`). In that case all controls have to
+	belong to that control class. This usage is deprecated, instead
+	just use ``V4L2_CTRL_WHICH_CUR_VAL``. There are some very old
+	drivers that do not yet support ``V4L2_CTRL_WHICH_CUR_VAL`` and
+	that require a control class here. You can test for such drivers
+	by setting ctrl_class to ``V4L2_CTRL_WHICH_CUR_VAL`` and calling
+	VIDIOC_TRY_EXT_CTRLS with a count of 0. If that fails, then the
+	driver does not support ``V4L2_CTRL_WHICH_CUR_VAL``.
+    * - }
+      -
+    * - __u32
+      - ``count``
+      - The number of controls in the controls array. May also be zero.
+    * - __u32
+      - ``error_idx``
+      - Set by the driver in case of an error. If the error is associated
+	with a particular control, then ``error_idx`` is set to the index
+	of that control. If the error is not related to a specific
+	control, or the validation step failed (see below), then
+	``error_idx`` is set to ``count``. The value is undefined if the
+	ioctl returned 0 (success).
+
+	Before controls are read from/written to hardware a validation
+	step takes place: this checks if all controls in the list are
+	valid controls, if no attempt is made to write to a read-only
+	control or read from a write-only control, and any other up-front
+	checks that can be done without accessing the hardware. The exact
+	validations done during this step are driver dependent since some
+	checks might require hardware access for some devices, thus making
+	it impossible to do those checks up-front. However, drivers should
+	make a best-effort to do as many up-front checks as possible.
+
+	This check is done to avoid leaving the hardware in an
+	inconsistent state due to easy-to-avoid problems. But it leads to
+	another problem: the application needs to know whether an error
+	came from the validation step (meaning that the hardware was not
+	touched) or from an error during the actual reading from/writing
+	to hardware.
+
+	The, in hindsight quite poor, solution for that is to set
+	``error_idx`` to ``count`` if the validation failed. This has the
+	unfortunate side-effect that it is not possible to see which
+	control failed the validation. If the validation was successful
+	and the error happened while accessing the hardware, then
+	``error_idx`` is less than ``count`` and only the controls up to
+	``error_idx-1`` were read or written correctly, and the state of
+	the remaining controls is undefined.
+
+	Since :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` does not access hardware there is
+	also no need to handle the validation step in this special way, so
+	``error_idx`` will just be set to the control that failed the
+	validation step instead of to ``count``. This means that if
+	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` fails with ``error_idx`` set to ``count``,
+	then you can call :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` to try to discover the
+	actual control that failed the validation step. Unfortunately,
+	there is no ``TRY`` equivalent for :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.

+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_framebuffer`.
+
+
+Description
+===========
+
+Applications can use the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl
+to get and set the framebuffer parameters for a
+:ref:`Video Overlay <overlay>` or :ref:`Video Output Overlay <osd>`
+(OSD). The type of overlay is implied by the device type (capture or
+output device) and can be determined with the
+:ref:`VIDIOC_QUERYCAP` ioctl. One ``/dev/videoN``
+device must not support both kinds of overlay.
+
+The V4L2 API distinguishes destructive and non-destructive overlays. A
+destructive overlay copies captured video images into the video memory
+of a graphics card. A non-destructive overlay blends video images into a
+VGA signal or graphics into a video signal. *Video Output Overlays* are
+always non-destructive.
+
+To get the current parameters applications call the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl with a pointer to a struct :c:type:`v4l2_framebuffer`
+structure. The driver fills all fields of the structure or returns an
+EINVAL error code when overlays are not supported.
+
+To set the parameters for a *Video Output Overlay*, applications must
+initialize the ``flags`` field of a struct
+:c:type:`v4l2_framebuffer`. Since the framebuffer is
+implemented on the TV card all other parameters are determined by the
+driver. When an application calls :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` with a pointer to
+this structure, the driver prepares for the overlay and returns the
+framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` does, or it returns an error
+code.
+
+To set the parameters for a *non-destructive Video Overlay*,
+applications must initialize the ``flags`` field, the ``fmt``
+substructure, and call :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. Again the driver prepares for
+the overlay and returns the framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+does, or it returns an error code.
+
+For a *destructive Video Overlay* applications must additionally provide
+a ``base`` address. Setting up a DMA to a random memory location can
+jeopardize the system security, its stability or even damage the
+hardware, therefore only the superuser can set the parameters for a
+destructive video overlay.

+	including ``V4L2_PIX_FMT_YUYV`` and ``V4L2_PIX_FMT_UYVY``) and the
+	``V4L2_PIX_FMT_PAL8`` format are also permitted. The behavior of
+	the driver when an application requests a compressed format is
+	undefined. See :ref:`pixfmt` for information on pixel formats.
+    * -
+      - enum :c:type:`v4l2_field`
+      - ``field``
+      - Drivers and applications shall ignore this field. If applicable,
+	the field order is selected with the

+    * - :cspan:`3`
+
+	This field is irrelevant to *non-destructive Video Overlays*.
+
+	For *destructive Video Overlays* both applications and drivers can
+	set this field to request padding bytes at the end of each line.
+	Drivers however may ignore the requested value, returning
+	``width`` times bytes-per-pixel or a larger value required by the
+	hardware. That implies applications can just set this field to
+	zero to get a reasonable default.
+
+	For *Video Output Overlays* the driver must return a valid value.
+
+	Video hardware may access padding bytes, therefore they must
+	reside in accessible memory. Consider for example the case where
+	padding bytes after the last line of an image cross a system page
+	boundary. Capture devices may write padding bytes, the value is
+	undefined. Output devices ignore the contents of padding bytes.
+
+	When the image format is planar the ``bytesperline`` value applies
+	to the first plane and is divided by the same factor as the
+	``width`` field for the other planes. For example the Cb and Cr
+	planes of a YUV 4:2:0 image have half as many padding bytes
+	following each line as the Y plane. To avoid ambiguities drivers
+	must return a ``bytesperline`` value rounded up to a multiple of
+	the scale factor.
+    * -
+      - __u32
+      - ``sizeimage``
+      - This field is irrelevant to *non-destructive Video Overlays*. For
+	*destructive Video Overlays* applications must initialize this

+

+      - The device is capable of non-destructive overlays. When the driver
+	clears this flag, only destructive overlays are supported. There
+	are no drivers yet which support both destructive and

+	always non-destructive.
+    * - ``V4L2_FBUF_CAP_CHROMAKEY``

+      - The device supports clipping by chroma-keying the images. That is,

+    * - ``V4L2_FBUF_FLAG_OVERLAY``
+      - 0x0002
+      - If this flag is set for a video capture device, then the driver
+	will set the initial overlay size to cover the full framebuffer
+	size, otherwise the existing overlay size (as set by
+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) will be used. Only one
+	video capture driver (bttv) supports this flag. The use of this
+	flag for capture devices is deprecated. There is no way to detect
+	which drivers support this flag, so the only reliable method of
+	setting the overlay size is through
+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. If this flag is set for a
+	video output device, then the video output overlay window is
+	relative to the top-left corner of the framebuffer and restricted
+	to the size of the framebuffer. If it is cleared, then the video

+    * - ``V4L2_FBUF_FLAG_CHROMAKEY``

+    * - ``V4L2_FBUF_FLAG_LOCAL_ALPHA``
+      - 0x0008
+      - Use the alpha channel of the framebuffer to clip or blend
+	framebuffer pixels with video images. The blend function is:

+	The actual alpha depth depends on the framebuffer pixel format.
+    * - ``V4L2_FBUF_FLAG_GLOBAL_ALPHA``
+      - 0x0010
+      - Use a global alpha value to blend the framebuffer with video
+	images. The blend function is: output = (framebuffer pixel * alpha
+	+ video pixel * (255 - alpha)) / 255. The alpha value is
+	determined by the ``global_alpha`` field of struct
+	:c:type:`v4l2_window` and negotiated with the

+    * - ``V4L2_FBUF_FLAG_SRC_CHROMAKEY``
+      - 0x0040
+      - Use source chroma-keying. The source chroma-key color is

+
+``argp``
+    Pointer to struct :c:type:`v4l2_format`.
+
+
+Description
+===========
+
+These ioctls are used to negotiate the format of data (typically image
+format) exchanged between driver and application.
+
+To query the current parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to the respective buffer (stream)
+type. For example video capture devices use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. When the application calls the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this structure the driver fills
+the respective member of the ``fmt`` union. In case of video capture
+devices that is either the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member. When the requested buffer type is not supported drivers return
+an ``EINVAL`` error code.
+
+To change the current format parameters applications initialize the
+``type`` field and all fields of the respective ``fmt`` union member.
+For details see the documentation of the various devices types in
+:ref:`devices`. Good practice is to query the current parameters
+first, and to modify only those parameters not suitable for the
+application. When the application calls the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with
+a pointer to a struct :c:type:`v4l2_format` structure the driver
+checks and adjusts the parameters against hardware abilities. Drivers
+should not return an error code unless the ``type`` field is invalid,
+this is a mechanism to fathom device capabilities and to approach
+parameters acceptable for both the application and driver. On success
+the driver may program the hardware, allocate resources and generally
+prepare for data exchange. Finally the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl returns
+the current format parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Very simple,
+inflexible devices may even ignore all input and always return the
+default parameters. However all V4L2 devices exchanging data with the
+application must implement the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. When the requested buffer type is not supported drivers return an
+EINVAL error code on a :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` attempt. When I/O is already in
+progress or the resource is not available for other reasons drivers
+return the ``EBUSY`` error code.
+
+The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl is equivalent to :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` with one
+exception: it does not change driver state. It can also be called at any
+time, never returning ``EBUSY``. This function is provided to negotiate
+parameters, to learn about hardware limitations, without disabling I/O
+or possibly time consuming hardware preparations. Although strongly
+recommended drivers are not required to implement this ioctl.
+
+The format as returned by :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` must be identical to what
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` returns for the same input or output.

+
+
+Description
+===========
+
+To get the current tuner or modulator radio frequency applications set
+the ``tuner`` field of a struct
+:c:type:`v4l2_frequency` to the respective tuner or
+modulator number (only input devices have tuners, only output devices
+have modulators), zero out the ``reserved`` array and call the
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this structure. The
+driver stores the current frequency in the ``frequency`` field.
+
+To change the current tuner or modulator radio frequency applications
+initialize the ``tuner``, ``type`` and ``frequency`` fields, and the
+``reserved`` array of a struct :c:type:`v4l2_frequency`
+and call the :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this
+structure. When the requested frequency is not possible the driver
+assumes the closest possible value. However :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` is a
+write-only ioctl, it does not return the actual new frequency.

+
+Description
+===========
+
+To query the current video input applications call the

+stores the number of the input, as in the struct
+:c:type:`v4l2_input` ``index`` field. This ioctl will fail

+
+To select a video input applications store the number of the desired
+input in an integer and call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` ioctl with a pointer
+to this integer. Side effects are possible. For example inputs may
+support different video standards, so the driver may implicitly switch
+the current standard. Because of these possible side effects
+applications must select an input before querying or negotiating any
+other parameters.
+
+Information about video inputs is available using the
+:ref:`VIDIOC_ENUMINPUT` ioctl.
+
+
+Return Value

+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+[to do]
+
+Ronald Bultje elaborates:
+
+APP is some application-specific information. The application can set it
+itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
+information for in an AVI or so). COM is the same, but it's comments,
+like 'encoded by me' or so.
+
+jpeg_markers describes whether the huffman tables, quantization tables
+and the restart interval information (all JPEG-specific stuff) should be
+stored in the JPEG-encoded fields. These define how the JPEG field is
+encoded. If you omit them, applications assume you've used standard
+encoding. You usually do want to add them.

+===========
+
+To query the attributes of a modulator applications initialize the

+:c:type:`v4l2_modulator` and call the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl with a pointer to this structure. Drivers
+fill the rest of the structure or return an ``EINVAL`` error code when the
+index is out of bounds. To enumerate all modulators applications shall
+begin at index zero, incrementing by one until the driver returns
+EINVAL.
+
+Modulators have two writable properties, an audio modulation set and the
+radio frequency. To change the modulated audio subprograms, applications
+initialize the ``index`` and ``txsubchans`` fields and the ``reserved``
+array and call the :ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Drivers may choose a
+different audio modulation if the request cannot be satisfied. However
+this is a write-only ioctl, it does not return the actual audio
+modulation selected.
+
+:ref:`SDR <sdr>` specific modulator types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``txsubchans`` field must be
+initialized to zero. The term 'modulator' means SDR transmitter in this
+context.
+
+To change the radio frequency the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

+
+
+Description
+===========
+
+The current video standard determines a nominal number of frames per
+second. If less than this number of frames is to be captured or output,
+applications can request frame skipping or duplicating on the driver
+side. This is especially useful when using the :ref:`read() <func-read>` or
+:ref:`write() <func-write>`, which are not augmented by timestamps or sequence
+counters, and to avoid unnecessary data copying.
+
+Changing the frame interval shall never change the format. Changing the
+format, on the other hand, may change the frame interval.
+
+Further these ioctls can be used to determine the number of buffers used
+internally by a driver in read/write mode. For implications see the
+section discussing the :ref:`read() <func-read>` function.
+
+To get and set the streaming parameters applications call the
+:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take a
+pointer to a struct :c:type:`v4l2_streamparm` which contains a
+union holding separate parameters for input and output devices.

+
+	-  An image capture operation may be significantly slower than

+
+Description
+===========
+
+The ioctls are used to query and configure selection rectangles.
+
+To query the cropping (composing) rectangle set struct
+:c:type:`v4l2_selection` ``type`` field to the
+respective buffer type. The next step is setting the
+value of struct :c:type:`v4l2_selection` ``target``
+field to ``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer
+to table :ref:`v4l2-selections-common` or :ref:`selection-api` for
+additional targets. The ``flags`` and ``reserved`` fields of struct
+:c:type:`v4l2_selection` are ignored and they must be
+filled with zeros. The driver fills the rest of the structure or returns
+EINVAL error code if incorrect buffer type or target was used. If
+cropping (composing) is not supported then the active rectangle is not
+mutable and it is always equal to the bounds rectangle. Finally, the
+struct :c:type:`v4l2_rect` ``r`` rectangle is filled with
+the current cropping (composing) coordinates. The coordinates are
+expressed in driver-dependent units. The only exception are rectangles
+for images in raw formats, whose coordinates are always expressed in
+pixels.
+
+To change the cropping (composing) rectangle set the struct
+:c:type:`v4l2_selection` ``type`` field to the
+respective buffer type. The next step is setting the
+value of struct :c:type:`v4l2_selection` ``target`` to
+``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer to table
+:ref:`v4l2-selections-common` or :ref:`selection-api` for additional
+targets. The struct :c:type:`v4l2_rect` ``r`` rectangle need
+to be set to the desired active area. Field struct
+:c:type:`v4l2_selection` ``reserved`` is ignored and
+must be filled with zeros. The driver may adjust coordinates of the
+requested rectangle. An application may introduce constraints to control
+rounding behaviour. The struct :c:type:`v4l2_selection`
+``flags`` field must be set to one of the following:
+
+-  ``0`` - The driver can adjust the rectangle size freely and shall
+   choose a crop/compose rectangle as close as possible to the requested
+   one.
+
+-  ``V4L2_SEL_FLAG_GE`` - The driver is not allowed to shrink the
+   rectangle. The original rectangle must lay inside the adjusted one.
+
+-  ``V4L2_SEL_FLAG_LE`` - The driver is not allowed to enlarge the
+   rectangle. The adjusted rectangle must lay inside the original one.
+
+-  ``V4L2_SEL_FLAG_GE | V4L2_SEL_FLAG_LE`` - The driver must choose the
+   size exactly the same as in the requested rectangle.
+
+Please refer to :ref:`sel-const-adjust`.
+
+The driver may have to adjusts the requested dimensions against hardware
+limits and other parts as the pipeline, i.e. the bounds given by the
+capture/output window or TV display. The closest possible values of
+horizontal and vertical offset and sizes are chosen according to
+following priority:
+
+1. Satisfy constraints from struct
+   :c:type:`v4l2_selection` ``flags``.
+
+2. Adjust width, height, left, and top to hardware limits and
+   alignments.
+
+3. Keep center of adjusted rectangle as close as possible to the
+   original one.
+
+4. Keep width and height as close as possible to original ones.
+
+5. Keep horizontal and vertical offset as close as possible to original
+   ones.
+
+On success the struct :c:type:`v4l2_rect` ``r`` field
+contains the adjusted rectangle. When the parameters are unsuitable the
+application may modify the cropping (composing) or image parameters and
+repeat the cycle until satisfactory parameters have been negotiated. If
+constraints flags have to be violated at then ``ERANGE`` is returned. The
+error indicates that *there exist no rectangle* that satisfies the
+constraints.

+Description
+===========
+
+To query and select the current video standard applications use the
+:ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctls which take a pointer to a
+:ref:`v4l2_std_id <v4l2-std-id>` type as argument. :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`
+can return a single flag or a set of flags as in struct
+:c:type:`v4l2_standard` field ``id``. The flags must be
+unambiguous such that they appear in only one enumerated
+struct :c:type:`v4l2_standard` structure.
+
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` accepts one or more flags, being a write-only ioctl it
+does not return the actual new standard as :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` does. When
+no flags are given or the current input does not support the requested
+standard the driver returns an ``EINVAL`` error code. When the standard set
+is ambiguous drivers may return ``EINVAL`` or choose any of the requested
+standards. If the current input or output does not support standard
+video timings (e.g. if :ref:`VIDIOC_ENUMINPUT`
+does not set the ``V4L2_IN_CAP_STD`` flag), then ``ENODATA`` error code is
+returned.
+
+Calling ``VIDIOC_SUBDEV_S_STD`` on a subdev device node that has been registered
+in read-only mode is not allowed. An error is returned and the errno variable is
+set to ``-EPERM``.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+
+
+Description
+===========
+
+To query the attributes of a tuner applications initialize the ``index``
+field and zero out the ``reserved`` array of a struct
+:c:type:`v4l2_tuner` and call the ``VIDIOC_G_TUNER`` ioctl
+with a pointer to this structure. Drivers fill the rest of the structure
+or return an ``EINVAL`` error code when the index is out of bounds. To
+enumerate all tuners applications shall begin at index zero,
+incrementing by one until the driver returns ``EINVAL``.
+
+Tuners have two writable properties, the audio mode and the radio
+frequency. To change the audio mode, applications initialize the
+``index``, ``audmode`` and ``reserved`` fields and call the
+``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
+which is determined by the current video input. Drivers may choose a
+different audio mode if the requested mode is invalid or unsupported.
+Since this is a write-only ioctl, it does not return the actually
+selected audio mode.
+
+:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
+to zero. The term 'tuner' means SDR receiver in this context.
+
+To change the radio frequency the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

+	is set, in units of 1 Hz. If multiple frequency bands are

+      - :cspan:`1` The highest tunable frequency in units of 62.5 kHz,

+      - receiving stereo audio and a secondary audio program
+    * -
+      -
+      - ``MONO | STEREO``
+      - receiving mono or stereo audio, the hardware cannot distinguish
+    * -
+      -
+      - ``LANG1 | LANG2``
+      - receiving bilingual audio
+    * -
+      -
+      - ``MONO | STEREO | LANG1 | LANG2``
+      - receiving mono, stereo or bilingual audio
+    * -
+      -
+      - :cspan:`1`
+
+	When the ``V4L2_TUNER_CAP_STEREO``, ``_LANG1``, ``_LANG2`` or
+	``_SAP`` flag is cleared in the ``capability`` field, the
+	corresponding ``V4L2_TUNER_SUB_`` flag must not be set here.
+
+	This field is valid only if this is the tuner of the current video
+	input, or when the structure refers to a radio tuner.
+    * - __u32
+      - ``audmode``
+      - :cspan:`1`
+
+	The selected audio mode, see :ref:`tuner-audmode` for valid

+	and like a :ref:`control` it does not automatically
+	change unless the requested mode is invalid or unsupported. See
+	:ref:`tuner-matrix` for possible results when the selected and

+
+
+Description
+===========
+
+As the video/audio devices become more complicated it becomes harder to
+debug problems. When this ioctl is called the driver will output the
+current device status to the kernel log. This is particular useful when
+dealing with problems like no sound, no video and incorrectly tuned
+channels. Also many modern devices autodetect video and audio standards
+and this ioctl will report what the device thinks what the standard is.
+Mismatches may give an indication where the problem is.
+
+This ioctl is optional and not all drivers support it. It was introduced
+in Linux 2.6.15.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_buffer`.
+
+
+Description
+===========
+
+Applications call the ``VIDIOC_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``type`` field of a struct
+:c:type:`v4l2_buffer` to the same buffer type as was
+previously used with struct :c:type:`v4l2_format` ``type``
+and struct :c:type:`v4l2_requestbuffers` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`v4l2_buffer` returned
+by a :ref:`VIDIOC_QUERYBUF` ioctl will do as well.
+When the buffer is intended for output (``type`` is
+``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``,
+or ``V4L2_BUF_TYPE_VBI_OUTPUT``) applications must also initialize the
+``bytesused``, ``field`` and ``timestamp`` fields, see :ref:`buffer`
+for details. Applications must also set ``flags`` to 0. The
+``reserved2`` and ``reserved`` fields must be set to 0. When using the
+:ref:`multi-planar API <planar-apis>`, the ``m.planes`` field must
+contain a userspace pointer to a filled-in array of struct
+:c:type:`v4l2_plane` and the ``length`` field must be set
+to the number of elements in that array.
+
+To enqueue a :ref:`memory mapped <mmap>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_MMAP``. When ``VIDIOC_QBUF`` is called
+with a pointer to this structure the driver sets the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_QUEUED`` flags and clears
+the ``V4L2_BUF_FLAG_DONE`` flag in the ``flags`` field, or it returns an
+``EINVAL`` error code.
+
+To enqueue a :ref:`user pointer <userp>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_USERPTR``, the ``m.userptr`` field to
+the address of the buffer and ``length`` to its size. When the
+multi-planar API is used, ``m.userptr`` and ``length`` members of the
+passed array of struct :c:type:`v4l2_plane` have to be used
+instead. When ``VIDIOC_QBUF`` is called with a pointer to this structure
+the driver sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+memory pages of the buffer in physical memory, they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+To enqueue a :ref:`DMABUF <dmabuf>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_DMABUF`` and the ``m.fd`` field to a
+file descriptor associated with a DMABUF buffer. When the multi-planar
+API is used the ``m.fd`` fields of the passed array of struct
+:c:type:`v4l2_plane` have to be used instead. When
+``VIDIOC_QBUF`` is called with a pointer to this structure the driver
+sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+buffer. Locking a buffer means passing it to a driver for a hardware
+access (usually DMA). If an application accesses (reads/writes) a locked
+buffer then the result is undefined. Buffers remain locked until
+dequeued, until the :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+The ``request_fd`` field can be used with the ``VIDIOC_QBUF`` ioctl to specify
+the file descriptor of a :ref:`request <media-request-api>`, if requests are
+in use. Setting it means that the buffer will not be passed to the driver
+until the request itself is queued. Also, the driver will apply any
+settings associated with the request for this buffer. This field will
+be ignored unless the ``V4L2_BUF_FLAG_REQUEST_FD`` flag is set.
+If the device does not support requests, then ``EBADR`` will be returned.
+If requests are supported but an invalid request file descriptor is given,
+then ``EINVAL`` will be returned.
+
+.. caution::
+   It is not allowed to mix queuing requests with queuing buffers directly.
+   ``EBUSY`` will be returned if the first buffer was queued directly and
+   then the application tries to queue a request, or vice versa. After
+   closing the file descriptor, calling
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or calling :ref:`VIDIOC_REQBUFS`
+   the check for this will be reset.
+
+   For :ref:`memory-to-memory devices <mem2mem>` you can specify the
+   ``request_fd`` only for output buffers, not for capture buffers. Attempting
+   to specify this for a capture buffer will result in an ``EBADR`` error.
+
+Applications call the ``VIDIOC_DQBUF`` ioctl to dequeue a filled
+(capturing) or displayed (output) buffer from the driver's outgoing
+queue. They just set the ``type``, ``memory`` and ``reserved`` fields of
+a struct :c:type:`v4l2_buffer` as above, when
+``VIDIOC_DQBUF`` is called with a pointer to this structure the driver
+fills the remaining fields or returns an error code. The driver may also
+set ``V4L2_BUF_FLAG_ERROR`` in the ``flags`` field. It indicates a
+non-critical (recoverable) streaming error. In such case the application
+may continue as normal, but should be aware that data in the dequeued
+buffer might be corrupted. When using the multi-planar API, the planes
+array must be passed in as well.
+
+If the application sets the ``memory`` field to ``V4L2_MEMORY_DMABUF`` to
+dequeue a :ref:`DMABUF <dmabuf>` buffer, the driver fills the ``m.fd`` field
+with a file descriptor numerically the same as the one given to ``VIDIOC_QBUF``
+when the buffer was enqueued. No new file descriptor is created at dequeue time
+and the value is only for the application convenience. When the multi-planar
+API is used the ``m.fd`` fields of the passed array of struct
+:c:type:`v4l2_plane` are filled instead.
+
+By default ``VIDIOC_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <func-open>` function, ``VIDIOC_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`v4l2_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EAGAIN
+    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+    buffer was in the outgoing queue.
+
+EINVAL
+    The buffer ``type`` is not supported, or the ``index`` is out of
+    bounds, or no buffers have been allocated yet, or the ``userptr`` or
+    ``length`` are invalid, or the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was
+    set but the the given ``request_fd`` was invalid, or ``m.fd`` was
+    an invalid DMABUF file descriptor.
+
+EIO
+    ``VIDIOC_DQBUF`` failed due to an internal error. Can also indicate
+    temporary problems like signal loss.
+
+    .. note::
+
+       The driver might dequeue an (empty) buffer despite returning
+       an error, or even stop capturing. Reusing such buffer may be unsafe
+       though and its details (e.g. ``index``) may not be returned either.
+       It is recommended that drivers indicate recoverable errors by setting
+       the ``V4L2_BUF_FLAG_ERROR`` and returning 0 instead. In that case the
+       application should be able to safely reuse the buffer and continue
+       streaming.
+
+EPIPE
+    ``VIDIOC_DQBUF`` returns this on an empty capture queue for mem2mem
+    codecs if a buffer with the ``V4L2_BUF_FLAG_LAST`` was already
+    dequeued and no new buffers are expected to become available.
+
+EBADR
+    The ``V4L2_BUF_FLAG_REQUEST_FD`` flag was set but the device does not
+    support requests for the given buffer type, or
+    the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was not set but the device requires
+    that the buffer is part of a request.
+
+EBUSY
+    The first buffer was queued via a request, but the application now tries
+    to queue it directly, or vice versa (it is not permitted to mix the two
+    APIs).

+

+

+    Pointer to struct :c:type:`v4l2_dv_timings`.
+
+
+Description
+===========
+
+The hardware may be able to detect the current DV timings automatically,
+similar to sensing the video standard. To do so, applications call
+:ref:`VIDIOC_QUERY_DV_TIMINGS` with a pointer to a struct
+:c:type:`v4l2_dv_timings`. Once the hardware detects
+the timings, it will fill in the timings structure.
+
+.. note::
+
+   Drivers shall *not* switch timings automatically if new
+   timings are detected. Instead, drivers should send the
+   ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support this) and expect
+   that userspace will take action by calling :ref:`VIDIOC_QUERY_DV_TIMINGS`.
+   The reason is that new timings usually mean different buffer sizes as
+   well, and you cannot change buffer sizes on the fly. In general,
+   applications that receive the Source Change event will have to call
+   :ref:`VIDIOC_QUERY_DV_TIMINGS`, and if the detected timings are valid they
+   will have to stop streaming, set the new timings, allocate new buffers
+   and start streaming again.
+
+If the timings could not be detected because there was no signal, then
+ENOLINK is returned. If a signal was detected, but it was unstable and
+the receiver could not lock to the signal, then ``ENOLCK`` is returned. If
+the receiver could lock to the signal, but the format is unsupported
+(e.g. because the pixelclock is out of range of the hardware
+capabilities), then the driver fills in whatever timings it could find
+and returns ``ERANGE``. In that case the application can call
+:ref:`VIDIOC_DV_TIMINGS_CAP` to compare the
+found timings with the hardware's capabilities in order to give more
+precise feedback to the user.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENODATA
+    Digital video timings are not supported for this input or output.
+
+ENOLINK
+    No timings could be detected because no signal was found.
+
+ENOLCK
+    The signal was unstable and the hardware could not lock on to it.
+
+ERANGE
+    Timings were found, but they are out of range of the hardware
+    capabilities.

+
+``argp``
+    Pointer to struct :c:type:`v4l2_buffer`.
+
+
+Description
+===========
+
+This ioctl is part of the :ref:`streaming <mmap>` I/O method. It can
+be used to query the status of a buffer at any time after buffers have
+been allocated with the :ref:`VIDIOC_REQBUFS` ioctl.
+
+Applications set the ``type`` field of a struct
+:c:type:`v4l2_buffer` to the same buffer type as was
+previously used with struct :c:type:`v4l2_format` ``type``
+and struct :c:type:`v4l2_requestbuffers` ``type``,
+and the ``index`` field. Valid index numbers range from zero to the
+number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. The ``reserved`` and ``reserved2`` fields must be set to 0. When
+using the :ref:`multi-planar API <planar-apis>`, the ``m.planes``
+field must contain a userspace pointer to an array of struct
+:c:type:`v4l2_plane` and the ``length`` field has to be set
+to the number of elements in that array. After calling
+:ref:`VIDIOC_QUERYBUF` with a pointer to this structure drivers return an
+error code or fill the rest of the structure.
+
+In the ``flags`` field the ``V4L2_BUF_FLAG_MAPPED``,
+``V4L2_BUF_FLAG_PREPARED``, ``V4L2_BUF_FLAG_QUEUED`` and
+``V4L2_BUF_FLAG_DONE`` flags will be valid. The ``memory`` field will be
+set to the current I/O method. For the single-planar API, the
+``m.offset`` contains the offset of the buffer from the start of the
+device memory, the ``length`` field its size. For the multi-planar API,
+fields ``m.mem_offset`` and ``length`` in the ``m.planes`` array
+elements will be used instead and the ``length`` field of struct
+:c:type:`v4l2_buffer` is set to the number of filled-in
+array elements. The driver may or may not set the remaining fields and
+flags, they are meaningless in this context.
+
+The struct :c:type:`v4l2_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+    The buffer ``type`` is not supported, or the ``index`` is out of
+    bounds.

+
+
+Description
+===========
+
+All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to
+identify kernel devices compatible with this specification and to obtain
+information about driver and hardware capabilities. The ioctl takes a
+pointer to a struct :c:type:`v4l2_capability` which is
+filled by the driver. When the driver is not compatible with this
+specification the ioctl returns an ``EINVAL`` error code.

+
+    * - __u8
+      - ``driver``\ [16]
+      - Name of the driver, a unique NUL-terminated ASCII string. For
+	example: "bttv". Driver specific applications can use this
+	information to verify the driver identity. It is also useful to
+	work around known bugs, or to identify drivers in error reports.
+
+	Storing strings in fixed sized arrays is bad practice but
+	unavoidable here. Drivers and applications should take precautions
+	to never read or write beyond the end of the array and to make
+	sure the strings are properly NUL-terminated.
+    * - __u8
+      - ``card``\ [32]
+      - Name of the device, a NUL-terminated UTF-8 string. For example:
+	"Yoyodyne TV/FM". One driver may support different brands or
+	models of video hardware. This information is intended for users,
+	for example in a menu of available devices. Since multiple TV
+	cards of the same brand may be installed which are supported by
+	the same driver, this name should be combined with the character
+	device file name (e. g. ``/dev/video2``) or the ``bus_info``
+	string to avoid ambiguities.
+    * - __u8
+      - ``bus_info``\ [32]
+      - Location of the device in the system, a NUL-terminated ASCII
+	string. For example: "PCI:0000:05:06.0". This information is
+	intended for users, to distinguish multiple identical devices. If
+	no such information is available the field must simply count the
+	devices controlled by the driver ("platform:vivid-000"). The
+	bus_info must start with "PCI:" for PCI boards, "PCIe:" for PCI
+	Express boards, "usb-" for USB devices, "I2C:" for i2c devices,
+	"ISA:" for ISA devices, "parport" for parallel port devices and
+	"platform:" for platform devices.
+    * - __u32
+      - ``version``
+      - Version number of the driver.
+
+	Starting with kernel 3.1, the version reported is provided by the
+	V4L2 subsystem following the kernel numbering scheme. However, it
+	may not always return the same version as the kernel if, for
+	example, a stable or distribution-modified kernel uses the V4L2
+	stack from a newer kernel.
+
+	The version number is formatted using the ``KERNEL_VERSION()``
+	macro. For example if the media stack corresponds to the V4L2
+	version shipped with Kernel 4.14, it would be equivalent to:
+    * - :cspan:`2`
+
+	``#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))``
+
+	``__u32 version = KERNEL_VERSION(4, 14, 0);``
+
+	``printf ("Version: %u.%u.%u\\n",``
+
+	``(version >> 16) & 0xFF, (version >> 8) & 0xFF, version & 0xFF);``
+    * - __u32
+      - ``capabilities``
+      - Available capabilities of the physical device as a whole, see
+	:ref:`device-capabilities`. The same physical device can export
+	multiple devices in /dev (e.g. /dev/videoX, /dev/vbiY and
+	/dev/radioZ). The ``capabilities`` field should contain a union of
+	all capabilities available around the several V4L2 devices
+	exported to userspace. For all those devices the ``capabilities``
+	field returns the same set of capabilities. This allows
+	applications to open just one of the devices (typically the video
+	device) and discover whether video, vbi and/or radio are also
+	supported.
+    * - __u32
+      - ``device_caps``
+      - Device capabilities of the opened device, see
+	:ref:`device-capabilities`. Should contain the available
+	capabilities of that specific device node. So, for example,
+	``device_caps`` of a radio device will only contain radio related
+	capabilities and no video or vbi capabilities. This field is only
+	set if the ``capabilities`` field contains the
+	``V4L2_CAP_DEVICE_CAPS`` capability. Only the ``capabilities``
+	field can have the ``V4L2_CAP_DEVICE_CAPS`` capability,
+	``device_caps`` will never set ``V4L2_CAP_DEVICE_CAPS``.
+    * - __u32
+      - ``reserved``\ [3]
+      - Reserved for future extensions. Drivers must set this array to
+	zero.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_queryctrl`, :c:type:`v4l2_query_ext_ctrl`
+    or :c:type:`v4l2_querymenu` (depending on the ioctl).
+
+
+Description
+===========
+
+To query the attributes of a control applications set the ``id`` field
+of a struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` and call the
+``VIDIOC_QUERYCTRL`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` is invalid.
+
+It is possible to enumerate controls by calling ``VIDIOC_QUERYCTRL``
+with successive ``id`` values starting from ``V4L2_CID_BASE`` up to and
+exclusive ``V4L2_CID_LASTP1``. Drivers may return ``EINVAL`` if a control in
+this range is not supported. Further applications can enumerate private
+controls, which are not defined in this specification, by starting at
+``V4L2_CID_PRIVATE_BASE`` and incrementing ``id`` until the driver
+returns ``EINVAL``.
+
+In both cases, when the driver sets the ``V4L2_CTRL_FLAG_DISABLED`` flag
+in the ``flags`` field this control is permanently disabled and should
+be ignored by the application. [#f1]_
+
+When the application ORs ``id`` with ``V4L2_CTRL_FLAG_NEXT_CTRL`` the
+driver returns the next supported non-compound control, or ``EINVAL`` if
+there is none. In addition, the ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` flag
+can be specified to enumerate all compound controls (i.e. controls with
+type ≥ ``V4L2_CTRL_COMPOUND_TYPES`` and/or array control, in other words
+controls that contain more than one value). Specify both
+``V4L2_CTRL_FLAG_NEXT_CTRL`` and ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` in
+order to enumerate all controls, compound or not. Drivers which do not
+support these flags yet always return ``EINVAL``.
+
+The ``VIDIOC_QUERY_EXT_CTRL`` ioctl was introduced in order to better
+support controls that can use compound types, and to expose additional
+control information that cannot be returned in struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` since that structure is full.
+
+``VIDIOC_QUERY_EXT_CTRL`` is used in the same way as
+``VIDIOC_QUERYCTRL``, except that the ``reserved`` array must be zeroed
+as well.
+
+Additional information is required for menu controls: the names of the
+menu items. To query them applications set the ``id`` and ``index``
+fields of struct :ref:`v4l2_querymenu <v4l2-querymenu>` and call the
+``VIDIOC_QUERYMENU`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` or ``index`` is invalid. Menu items are enumerated by calling
+``VIDIOC_QUERYMENU`` with successive ``index`` values from struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` ``minimum`` to ``maximum``,
+inclusive.
+
+.. note::
+
+   It is possible for ``VIDIOC_QUERYMENU`` to return
+   an ``EINVAL`` error code for some indices between ``minimum`` and
+   ``maximum``. In that case that particular menu item is not supported by
+   this driver. Also note that the ``minimum`` value is not necessarily 0.
+
+See also the examples in :ref:`control`.

+
+	Generally drivers should not scale hardware control values. It may

+
+	This field gives the smallest change of an integer control
+	actually affecting hardware. Often the information is needed when
+	the user can change controls by keyboard or GUI buttons, rather
+	than a slider. When for example a hardware register accepts values
+	0-511 and the driver reports 0-65535, step should be 128.

+    * - ``V4L2_CTRL_FLAG_VOLATILE``
+      - 0x0080
+      - This control is volatile, which means that the value of the

+	current gain value if the device is in auto-gain mode. In such a
+	case the hardware calculates the gain value based on the lighting
+	conditions which can change over time.
+
+	.. note::
+
+	   Setting a new value for a volatile control will be ignored
+	   unless
+	   :ref:`V4L2_CTRL_FLAG_EXECUTE_ON_WRITE <FLAG_EXECUTE_ON_WRITE>`
+	   is also set.
+	   Setting a new value for a volatile control will *never* trigger a

+    * - ``V4L2_CTRL_FLAG_HAS_PAYLOAD``
+      - 0x0100
+      - This control has a pointer type, so its value has to be accessed
+	using one of the pointer fields of struct
+	:c:type:`v4l2_ext_control`. This flag is set
+	for controls that are an array, string, or have a compound type.
+	In all cases you have to set a pointer to memory containing the
+	payload of the control.
+    * .. _FLAG_EXECUTE_ON_WRITE:
+
+      - ``V4L2_CTRL_FLAG_EXECUTE_ON_WRITE``
+      - 0x0200
+      - The value provided to the control will be propagated to the driver
+	even if it remains constant. This is required when the control
+	represents an action on the hardware. For example: clearing an
+	error flag or triggering the flash. All the controls of the type
+	``V4L2_CTRL_TYPE_BUTTON`` have this flag set.
+    * .. _FLAG_MODIFY_LAYOUT:
+
+      - ``V4L2_CTRL_FLAG_MODIFY_LAYOUT``
+      - 0x0400
+      - Changing this control value may modify the layout of the
+        buffer (for video devices) or the media bus format (for sub-devices).
+
+	A typical example would be the ``V4L2_CID_ROTATE`` control.
+
+	Note that typically controls with this flag will also set the
+	``V4L2_CTRL_FLAG_GRABBED`` flag when buffers are allocated or
+	streaming is in progress since most drivers do not support changing
+	the format in that case.

+
+
+Description
+===========
+
+The hardware may be able to detect the current video standard
+automatically. To do so, applications call :ref:`VIDIOC_QUERYSTD` with a
+pointer to a :ref:`v4l2_std_id <v4l2-std-id>` type. The driver
+stores here a set of candidates, this can be a single flag or a set of
+supported standards if for example the hardware can only distinguish
+between 50 and 60 Hz systems. If no signal was detected, then the driver
+will return V4L2_STD_UNKNOWN. When detection is not possible or fails,
+the set must contain all standards supported by the current video input
+or output.
+
+.. note::
+
+   Drivers shall *not* switch the video standard
+   automatically if a new video standard is detected. Instead, drivers
+   should send the ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support
+   this) and expect that userspace will take action by calling
+   :ref:`VIDIOC_QUERYSTD`. The reason is that a new video standard can mean
+   different buffer sizes as well, and you cannot change buffer sizes on
+   the fly. In general, applications that receive the Source Change event
+   will have to call :ref:`VIDIOC_QUERYSTD`, and if the detected video
+   standard is valid they will have to stop streaming, set the new
+   standard, allocate new buffers and start streaming again.
+
+

+VIDIOC_REQBUFS - Initiate Memory Mapping, User Pointer I/O or DMA buffer I/O
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_REQBUFS, struct v4l2_requestbuffers *argp )
+    :name: VIDIOC_REQBUFS
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_requestbuffers`.
+
+Description
+===========
+
+This ioctl is used to initiate :ref:`memory mapped <mmap>`,
+:ref:`user pointer <userp>` or :ref:`DMABUF <dmabuf>` based I/O.
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`v4l2_requestbuffers` structure. They set the ``type``
+field to the respective stream or buffer type, the ``count`` field to
+the desired number of buffers, ``memory`` must be set to the requested
+I/O method and the ``reserved`` array must be zeroed. When the ioctl is
+called with a pointer to this structure the driver will attempt to
+allocate the requested number of buffers and it stores the actual number
+allocated in the ``count`` field. It can be smaller than the number
+requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. For example video output requires at least two
+buffers, one displayed and one filled by the application.
+
+When the I/O method is not supported the ioctl returns an ``EINVAL`` error
+code.
+
+Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of
+buffers. Note that if any buffers are still mapped or exported via DMABUF,
+then :ref:`VIDIOC_REQBUFS` can only succeed if the
+``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` capability is set. Otherwise
+:ref:`VIDIOC_REQBUFS` will return the ``EBUSY`` error code.
+If ``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` is set, then these buffers are
+orphaned and will be freed when they are unmapped or when the exported DMABUF
+fds are closed. A ``count`` value of zero frees or orphans all buffers, after
+aborting or finishing any DMA in progress, an implicit
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`.

+
+Description
+===========
+
+Start a hardware frequency seek from the current frequency. To do this
+applications initialize the ``tuner``, ``type``, ``seek_upward``,
+``wrap_around``, ``spacing``, ``rangelow`` and ``rangehigh`` fields, and
+zero out the ``reserved`` array of a struct
+:c:type:`v4l2_hw_freq_seek` and call the
+``VIDIOC_S_HW_FREQ_SEEK`` ioctl with a pointer to this structure.
+
+The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
+to tell the driver to search a specific band. If the struct
+:c:type:`v4l2_tuner` ``capability`` field has the
+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag set, these values must fall
+within one of the bands returned by
+:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag is not set, then these values
+must exactly match those of one of the bands returned by
+:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
+current frequency of the tuner does not fall within the selected band it
+will be clamped to fit in the band before the seek is started.
+
+If an error is returned, then the original frequency will be restored.
+
+This ioctl is supported if the ``V4L2_CAP_HW_FREQ_SEEK`` capability is

+
+.. c:function:: int ioctl( int fd, VIDIOC_STREAMOFF, const int *argp )
+    :name: VIDIOC_STREAMOFF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to an integer.
+
+Description
+===========
+
+The ``VIDIOC_STREAMON`` and ``VIDIOC_STREAMOFF`` ioctl start and stop
+the capture or output process during streaming
+(:ref:`memory mapping <mmap>`, :ref:`user pointer <userp>` or
+:ref:`DMABUF <dmabuf>`) I/O.
+
+Capture hardware is disabled and no input buffers are filled (if there
+are any empty buffers in the incoming queue) until ``VIDIOC_STREAMON``
+has been called. Output hardware is disabled and no video signal is
+produced until ``VIDIOC_STREAMON`` has been called. The ioctl will
+succeed when at least one output buffer is in the incoming queue.
+
+Memory-to-memory devices will not start until ``VIDIOC_STREAMON`` has
+been called for both the capture and output stream types.
+
+If ``VIDIOC_STREAMON`` fails then any already queued buffers will remain
+queued.
+
+The ``VIDIOC_STREAMOFF`` ioctl, apart of aborting or finishing any DMA
+in progress, unlocks any user pointer buffers locked in physical memory,
+and it removes all buffers from the incoming and outgoing queues. That
+means all images captured but not dequeued yet will be lost, likewise
+all images enqueued for output but not transmitted yet. I/O returns to
+the same state as after calling
+:ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+If buffers have been queued with :ref:`VIDIOC_QBUF` and
+``VIDIOC_STREAMOFF`` is called without ever having called
+``VIDIOC_STREAMON``, then those queued buffers will also be removed from
+the incoming queue and all are returned to the same state as after
+calling :ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+Both ioctls take a pointer to an integer, the desired buffer or stream
+type. This is the same as struct
+:c:type:`v4l2_requestbuffers` ``type``.
+
+If ``VIDIOC_STREAMON`` is called when streaming is already in progress,
+or if ``VIDIOC_STREAMOFF`` is called when streaming is already stopped,
+then 0 is returned. Nothing happens in the case of ``VIDIOC_STREAMON``,
+but ``VIDIOC_STREAMOFF`` will return queued buffers to their starting

+VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL - Enumerate frame intervals
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, struct v4l2_subdev_frame_interval_enum * argp )
+    :name: VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_subdev_frame_interval_enum`.
+
+
+Description
+===========
+
+This ioctl lets applications enumerate available frame intervals on a
+given sub-device pad. Frame intervals only makes sense for sub-devices
+that can control the frame period on their own. This includes, for
+instance, image sensors and TV tuners.
+
+For the common use case of image sensors, the frame intervals available
+on the sub-device output pad depend on the frame format and size on the
+same pad. Applications must thus specify the desired format and size
+when enumerating frame intervals.
+
+To enumerate frame intervals applications initialize the ``index``,
+``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
+:c:type:`v4l2_subdev_frame_interval_enum`
+and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
+to this structure. Drivers fill the rest of the structure or return an
+EINVAL error code if one of the input fields is invalid. All frame
+intervals are enumerable by beginning at index zero and incrementing by
+one until ``EINVAL`` is returned.
+
+Available frame intervals may depend on the current 'try' formats at
+other pads of the sub-device, as well as on the current active links.
+See :ref:`VIDIOC_SUBDEV_G_FMT` for more
+information about the try formats.
+
+Sub-devices that support the frame interval enumeration ioctl should
+implemented it on a single pad only. Its behaviour when supported on
+multiple pads of the same sub-device is not defined.

+
+
+Description
+===========
+
+This ioctl allows applications to enumerate all frame sizes supported by
+a sub-device on the given pad for the given media bus format. Supported
+formats can be retrieved with the
+:ref:`VIDIOC_SUBDEV_ENUM_MBUS_CODE`
+ioctl.
+
+To enumerate frame sizes applications initialize the ``pad``, ``which``
+, ``code`` and ``index`` fields of the struct
+:c:type:`v4l2_subdev_mbus_code_enum` and
+call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_SIZE` ioctl with a pointer to the
+structure. Drivers fill the minimum and maximum frame sizes or return an
+EINVAL error code if one of the input parameters is invalid.
+
+Sub-devices that only support discrete frame sizes (such as most
+sensors) will return one or more frame sizes with identical minimum and
+maximum values.
+
+Not all possible sizes in given [minimum, maximum] ranges need to be
+supported. For instance, a scaler that uses a fixed-point scaling ratio
+might not be able to produce every frame size between the minimum and
+maximum values. Applications must use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl to try the
+sub-device for an exact supported frame size.
+
+Available frame sizes may depend on the current 'try' formats at other
+pads of the sub-device, as well as on the current active links and the
+current values of V4L2 controls. See
+:ref:`VIDIOC_SUBDEV_G_FMT` for more

+===========
+
+.. note::
+
+    This is an :ref:`obsolete` interface and may be removed
+    in the future. It is superseded by
+    :ref:`the selection API <VIDIOC_SUBDEV_G_SELECTION>`.
+
+To retrieve the current crop rectangle applications set the ``pad``
+field of a struct :c:type:`v4l2_subdev_crop` to the

+to ``V4L2_SUBDEV_FORMAT_ACTIVE``. They then call the

+code if the input arguments are invalid, or if cropping is not supported
+on the given pad.
+
+To change the current crop rectangle applications set both the ``pad``
+and ``which`` fields and all members of the ``rect`` field. They then
+call the ``VIDIOC_SUBDEV_S_CROP`` ioctl with a pointer to this
+structure. The driver verifies the requested crop rectangle, adjusts it

+Applications can query the device capabilities by setting the ``which``

+crop rectangles and stored in the sub-device file handle. Two
+applications querying the same sub-device would thus not interact with
+each other.
+
+If the subdev device node has been registered in read-only mode, calls to
+``VIDIOC_SUBDEV_S_CROP`` are only valid if the ``which`` field is set to
+``V4L2_SUBDEV_FORMAT_TRY``, otherwise an error is returned and the errno
+variable is set to ``-EPERM``.
+
+Drivers must not return an error solely because the requested crop
+rectangle doesn't match the device capabilities. They must instead

+
+
+Description
+===========
+
+These ioctls are used to negotiate the frame format at specific subdev
+pads in the image pipeline.
+
+To retrieve the current format applications set the ``pad`` field of a
+struct :c:type:`v4l2_subdev_format` to the desired
+pad number as reported by the media API and the ``which`` field to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. When they call the
+``VIDIOC_SUBDEV_G_FMT`` ioctl with a pointer to this structure the
+driver fills the members of the ``format`` field.
+
+To change the current format applications set both the ``pad`` and
+``which`` fields and all members of the ``format`` field. When they call
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl with a pointer to this structure the
+driver verifies the requested format, adjusts it based on the hardware
+capabilities and configures the device. Upon return the struct
+:c:type:`v4l2_subdev_format` contains the current
+format as would be returned by a ``VIDIOC_SUBDEV_G_FMT`` call.
+
+Applications can query the device capabilities by setting the ``which``
+to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' formats are not applied
+to the device by the driver, but are changed exactly as active formats
+and stored in the sub-device file handle. Two applications querying the
+same sub-device would thus not interact with each other.
+
+For instance, to try a format at the output pad of a sub-device,
+applications would first set the try format at the sub-device input with
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl. They would then either retrieve the
+default format at the output pad with the ``VIDIOC_SUBDEV_G_FMT`` ioctl,
+or set the desired output pad format with the ``VIDIOC_SUBDEV_S_FMT``
+ioctl and check the returned value.
+
+Try formats do not depend on active formats, but can depend on the
+current links configuration or sub-device controls value. For instance,
+a low-pass noise filter might crop pixels at the frame boundaries,
+modifying its output frame size.
+
+If the subdev device node has been registered in read-only mode, calls to
+``VIDIOC_SUBDEV_S_FMT`` are only valid if the ``which`` field is set to
+``V4L2_SUBDEV_FORMAT_TRY``, otherwise an error is returned and the errno
+variable is set to ``-EPERM``.
+
+Drivers must not return an error solely because the requested format
+doesn't match the device capabilities. They must instead modify the
+format to match what the hardware can provide. The modified format

+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_subdev_frame_interval`.
+
+
+Description
+===========
+
+These ioctls are used to get and set the frame interval at specific
+subdev pads in the image pipeline. The frame interval only makes sense
+for sub-devices that can control the frame period on their own. This
+includes, for instance, image sensors and TV tuners. Sub-devices that
+don't support frame intervals must not implement these ioctls.
+
+To retrieve the current frame interval applications set the ``pad``
+field of a struct
+:c:type:`v4l2_subdev_frame_interval` to
+the desired pad number as reported by the media controller API. When
+they call the ``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` ioctl with a pointer to
+this structure the driver fills the members of the ``interval`` field.
+
+To change the current frame interval applications set both the ``pad``
+field and all members of the ``interval`` field. When they call the
+``VIDIOC_SUBDEV_S_FRAME_INTERVAL`` ioctl with a pointer to this
+structure the driver verifies the requested interval, adjusts it based
+on the hardware capabilities and configures the device. Upon return the
+struct
+:c:type:`v4l2_subdev_frame_interval`
+contains the current frame interval as would be returned by a
+``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` call.
+
+Calling ``VIDIOC_SUBDEV_S_FRAME_INTERVAL`` on a subdev device node that has been
+registered in read-only mode is not allowed. An error is returned and the errno
+variable is set to ``-EPERM``.
+
+Drivers must not return an error solely because the requested interval
+doesn't match the device capabilities. They must instead modify the
+interval to match what the hardware can provide. The modified interval
+should be as close as possible to the original request.
+
+Changing the frame interval shall never change the format. Changing the
+format, on the other hand, may change the frame interval.
+
+Sub-devices that support the frame interval ioctls should implement them
+on a single pad only. Their behaviour when supported on multiple pads of
+the same sub-device is not defined.

+
+
+Description
+===========
+
+The selections are used to configure various image processing
+functionality performed by the subdevs which affect the image size. This
+currently includes cropping, scaling and composition.
+
+The selection API replaces
+:ref:`the old subdev crop API <VIDIOC_SUBDEV_G_CROP>`. All the
+function of the crop API, and more, are supported by the selections API.
+
+See :ref:`subdev` for more information on how each selection target
+affects the image processing pipeline inside the subdevice.
+
+If the subdev device node has been registered in read-only mode, calls to
+``VIDIOC_SUBDEV_S_SELECTION`` are only valid if the ``which`` field is set to
+``V4L2_SUBDEV_FORMAT_TRY``, otherwise an error is returned and the errno
+variable is set to ``-EPERM``.
+
+Types of selection targets
+--------------------------
+
+There are two types of selection targets: actual and bounds. The actual
+targets are the targets which configure the hardware. The BOUNDS target
+will return a rectangle that contain all possible actual rectangles.
+
+
+Discovering supported features
+------------------------------
+
+To discover which targets are supported, the user can perform
+``VIDIOC_SUBDEV_G_SELECTION`` on them. Any unsupported target will
+return ``EINVAL``.
+
+Selection targets and flags are documented in
+:ref:`v4l2-selections-common`.

+YUV Formats
+***********
+
+YUV is the format native to TV broadcast and composite video signals. It
+separates the brightness information (Y) from the color information (U
+and V or Cb and Cr). The color information consists of red and blue
+*color difference* signals, this way the green component can be
+reconstructed by subtracting from the brightness component. See
+:ref:`colorspaces` for conversion examples. YUV was chosen because
+early television would only transmit brightness information. To add
+color in a way compatible with existing receivers a new signal carrier
+was added to transmit the color difference signals. Secondary in the YUV
+format the U and V components usually have lower resolution than the Y
+component. This is an analog video compression technique taking
+advantage of a property of the human visual system, being more sensitive
+to brightness information.

+1. A single AtomISP driver needs to be implemented to support both
+   Baytrail (BYT and Cherrytail (CHT) platforms at the same time.
+   The current driver is a mechanical and hand combined merge of the
+   two using several runtime macros, plus some ifdef ISP2401 to select the
+   CHT version. Yet, there are some ISP-specific headers that change the
+   driver's behavior during compile time.
+
+2. The file structure needs to get tidied up to resemble a normal Linux
+   driver.
+
+3. Lots of the midlayer glue. unused code and abstraction needs removing.
+
+3. The sensor drivers read MIPI settings from EFI variables or default to the
+   settings hard-coded in the platform data file for different platforms.
+   It should be possible to improve it, by adding support for _DSM tables.
+
+4. The sensor drivers use PMIC and the regulator framework API. In the ideal
+   world it would be using ACPI but that's not how the existing devices work.
+
+5. The AtomISP driver includes some special IOCTLS (ATOMISP_IOC_XXXX_XXXX)
+   and controls that require some cleanup.
+
+6. Correct Coding Style. Please don't send coding style patches for this
+   driver until the other work is done.
+
+7. The ISP code has some dependencies of the exact FW version.
+   The version defined in pci/sh_css_firmware.c:
+   BYT:
+	static const char *isp2400_release_version = STR(irci_stable_candrpv_0415_20150521_0458);
+
+   CHT:
+	static const char *isp2401_release_version = STR(irci_ecr - master_20150911_0724);
+
+   Those versions don't seem to be available anymore. On the tests we've
+   done so far, this version also seems to work for isp2401:
+
+		irci_stable_candrpv_0415_20150521_0458
+
+   At some point we may need to round up a few driver versions and see if
+   there are any specific things that can be done to fold in support for
+   multiple firmware versions.
+
+8. Switch to V4L2 async API to set up sensor, lens and flash devices.
+   Control those devices using V4L2 sub-device API without custom
+   extensions.
+
+9. Switch to standard V4L2 sub-device API for sensor and lens. In
+   particular, the user space API needs to support V4L2 controls as
+   defined in the V4L2 spec and references to atomisp must be removed from
+   these drivers.
+
+10. Use LED flash API for flash LED drivers such as LM3554 (which already
+    has a LED class driver).
+
+11. Switch from videobuf1 to videobuf2. Videobuf1 is being removed!
+
+12. There are some memory management code that seems to be
+    forked from Kernel 3.10 inside hmm/ directory. Get rid of it,
+    making the driver to use a more standard memory management module.
+
+13. While the driver probes the hardware and reports itself as a
+    V4L2 driver, there are still some issues preventing it to
+    stream (at least it doesn't with the standard V4L2 applications.
+    Didn't test yet with some custom-made app for this driver).
+    Solving the related bugs and issues preventing it to work is
+    needed.
+
+Limitations:
+
+1. To test the patches, you also need the ISP firmware
+
+   for BYT: /lib/firmware/shisp_2400b0_v21.bin
+   for CHT: /lib/firmware/shisp_2401a0_v21.bin
+
+   The firmware files will usually be found in /etc/firmware on an Android
+   device but can also be extracted from the upgrade kit if you've managed
+   to lose them somehow.
+
+2. Without a 3A libary the capture behaviour is not very good. To take a good
+   picture, you need tune ISP parameters by IOCTL functions or use a 3A libary
+   such as libxcam.
+
+3. The driver is intended to drive the PCI exposed versions of the device.
+   It will not detect those devices enumerated via ACPI as a field of the
+   i915 GPU driver.
+
+4. The driver supports only v2 of the IPU/Camera. It will not work with the
+   versions of the hardware in other SoCs.

   decided whether this feature is useful enough to make it generally
   available by exporting to v4l2-core.
 
-- After all async subdevices have been bound, v4l2_fwnode_parse_link()
-  is used to form the media links between the devices discovered in
-  the OF graph.
-
-  While this approach allows support for arbitrary OF graphs, there
-  are some assumptions for this to work:
-
-  1. If a port owned by a device in the graph has endpoint nodes, the
-     port is treated as a media pad.
-
-     This presents problems for devices that don't make this port = pad
-     assumption. Examples are SMIAPP compatible cameras which define only
-     a single output port node, but which define multiple pads owned
-     by multiple subdevices (pixel-array, binner, scaler). Or video
-     decoders (entity function MEDIA_ENT_F_ATV_DECODER), which also define
-     only a single output port node, but define multiple pads for video,
-     VBI, and audio out.
-
-     A workaround at present is to set the port reg properties to
-     correspond to the media pad index that the port represents. A
-     possible long-term solution is to implement a subdev API that
-     maps a port id to a media pad index.
-
-  2. Every endpoint of a port owned by a device in the graph is treated
-     as a media link.
-
-     Which means a port must not contain mixed-use endpoints, they
-     must all refer to media links between V4L2 subdevices.
-
 - i.MX7: all of the above, since it uses the imx media core
 
 - i.MX7: use Frame Interval Monitor
