2011-04-27Commit FS#12069 - Playback rework - first stages. Gives as thorough as ↵Michael Sevakis
possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29785 a1c6a512-1295-4272-9138-f99709370657
2011-02-23Give playback engine better control over the codec. Codec simply follows ↵Michael Sevakis
commands and doesn't concern itself with audio state. Get track change notification in on the actual last buffer insert of the track because now audio simply waits for a track change notify from PCM on the last track and it must be sent reliably. This is still at an intermediate stage but works. Codecs and plugins become incompatible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29387 a1c6a512-1295-4272-9138-f99709370657
2011-01-30Use __builtin_constant_p() to select the best byteswapping method: constant ↵Michael Sevakis
or target optimized. Same macro can then be used for constant values and inits as well as non-constant. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29171 a1c6a512-1295-4272-9138-f99709370657
2010-07-01encoders are not built in sim buildsRafaël Carré
no need to check for SIMULATOR in the .c files git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27209 a1c6a512-1295-4272-9138-f99709370657
2010-05-06Make open() posix compliant api-wise. A few calls (those with O_CREAT) need ↵Thomas Martitz
the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25844 a1c6a512-1295-4272-9138-f99709370657

encoding while recording in mono. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22014 a1c6a512-1295-4272-9138-f99709370657
2008-11-28Recording: Change some encoder code the operation of which was apparantly ↵Michael Sevakis
unclear. It seems clearer now anyway. No functional changes. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19255 a1c6a512-1295-4272-9138-f99709370657
2008-10-08New recording setting to configure how mono recordings are made. Previously, ↵Peter D'Hoye
this was always L+R, which was kinda silly if your signal was on L only. This setting allows for L, R or L+R. SWCODEC only for now, to be added for HWCODEC (although that will only be L and L+R probably) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18745 a1c6a512-1295-4272-9138-f99709370657
2008-06-28Updated our source code header to explicitly mention that we are GPL v2 orDaniel Stenberg
later. We still need to hunt down snippets used that are not. 1324 modified files... http://www.rockbox.org/mail/archive/rockbox-dev-archive-2008-06/0060.shtml git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17847 a1c6a512-1295-4272-9138-f99709370657
2007-12-13Another fix for file system issues when encountering disk full (like when ↵Peter D'Hoye
recording) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15920 a1c6a512-1295-4272-9138-f99709370657
2007-11-30Move encoder CPU boost control to the core. Allow CPU to sleep a bit when ↵Michael Sevakis
PCM buffer is empty and save some power. Codec API becomes incompatible so full updates! :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15854 a1c6a512-1295-4272-9138-f99709370657
2007-10-10Fix FS #5852 by trying to properly close and update the recorded file, and ↵Peter D'Hoye
give the FAT the correct file info. Add filehandle checks to some file functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15072 a1c6a512-1295-4272-9138-f99709370657
2007-04-25Make recording complain about every little file I/O problem (error on ↵Michael Sevakis
close() failure and fsync() failure). Why? I guess we will find out the disk is full about 1/2 sector sooner on average when the file APIs actually detect this correctly. :/ git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13262 a1c6a512-1295-4272-9138-f99709370657
2007-03-29Accept FS#6918 - Remove Nested Functions by Tim Ross. Adjust some names. ↵Michael Sevakis
Hunt down and remove the remaining ones in the recording system as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12955 a1c6a512-1295-4272-9138-f99709370657
2007-03-04SWCODEC Recording Codecs: Fix problems with hanging recording screen ↵Michael Sevakis
(chiefly on x5) when no voice file present and source is not FMRadio. Caused by extra audio stops causing encoder to unload prematurely. Fix is to have separate stop flags for each codec type to prevent collisions. Also now safe to plug into USB when recording and encoder will stay loaded and not be stopped by the call to audio_stop_playback. Additional discovery: playback will not be able to restart after a USB plug during recording. Probably an old bug. I recommend in the future that recording have higher priority on system resources than playback and playback be denied access explicitly if recording requires them. Codec API becomes incompatible so do full updates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12579 a1c6a512-1295-4272-9138-f99709370657
2007-02-17ARM targets: Making a few functions non-static allows us to get rid of ↵Jens Arnold
-ffunction-sections, significantly decreasing binary size and making things run a bit faster because static functions are no longer long_call. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12349 a1c6a512-1295-4272-9138-f99709370657
2007-02-09Encoders: Add a little dithering with the fractional bit for mono mixdowns ↵Michael Sevakis
so faster shifts can be used again instead of division without introducing their own DC offset into the mixed channels. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12246 a1c6a512-1295-4272-9138-f99709370657

2006-11-29Add support for compiling encoders without adjustable CPU frequency and/or IRAM.Michael Sevakis
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11625 a1c6a512-1295-4272-9138-f99709370657
2006-11-26FS#6357, patch 1: let iramcopy and bss share the same space in codecs andTomasz Malesinski
plugins. Currently, in case of plugins using IRAM bss is cleared twice, once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only during codec initialization. Also, removed double variables in codecs storing a pointer to codec_api. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 a1c6a512-1295-4272-9138-f99709370657
2006-11-06Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis
SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657
