2009-03-13all: Update copyright header.Avuton Olrich
This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.
2009-03-12audio: moved mixer functions to mixer_control.cMax Kellermann
2009-02-11audio: moved code to output_command.cMax Kellermann
The output_command library provides a command interface to the audio outputs. It assumes the input comes from an untrusted source (i.e. the client) and verifies all parameters.
2009-02-11audio: replaced parseAudioConfig() with audio_format_parse()Max Kellermann
Added audio_format_parse() in a separate library, with a modern interface: return a GError instead of logging errors. This allows the caller to deal with the error.
2009-02-10audio: moved code to output_all.cMax Kellermann
Moved code which deals with all audio outputs at once into a separate library.
2009-02-10audio: moved protocol code to output_print.cMax Kellermann
2009-02-10audio: moved state file code to output_state.cMax Kellermann
2009-02-10audio: removed isCurrentAudioFormat()Max Kellermann
This function isn't used anymore.
2009-02-10audio: added output enumeration functionsMax Kellermann
Added audio_output_get(), audio_output_find().
2009-02-10audio: added audio_output_config_count()Max Kellermann
audio_output_config_count() returns the number of audio outputs in the configuration file. It is only used by initAudioDriver(). The public function audio_output_count() now returns audioOutputArraySize.
2009-01-25mixer: removed mixer_configure_legacy(), AC_MIXER_CONFIGUREMax Kellermann
Those have been superseded by the new legacy configuration code.
2009-01-17conf: no CamelCase, part IMax Kellermann
Renamed functions, types, variables.
2008-12-31Moving mixers to audio outputsViliam Mateicka
2008-12-31exporting functionsViliam Mateicka
2008-10-31added prefix to header macrosMax Kellermann
"LOG_H" is a macro which is also used by ffmpeg/log.h. This is ffmpeg's fault, because short macros should be reserved for applications, but since it's always a good idea to choose prefixed macro names, even for applications, we are going to do that in MPD.
2008-10-29output: use bool for return values and flagsMax Kellermann
Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
2008-10-08use the "bool" data type instead of "int"Max Kellermann
"bool" should be used in C99 programs for boolean values.
2008-10-08don't include os_compat.hMax Kellermann
When there are standardized headers, use these instead of the bloated os_compat.h.
2008-09-29audio_output: added method pause()Max Kellermann
pause() puts the audio output into pause mode: if supported, it may perform a special action, which keeps the device open, but does not play anything. Output plugins like "shout" might want to play silence during pause, so their clients won't be disconnected. Plugins which do not support pausing will simply be closed, and have to be reopened when unpaused. This pach includes an implementation for the shout plugin, which sends silence chunks.
2008-09-10audio: removed isAudioDeviceOpen()Max Kellermann
The function isAudioDeviceOpen() is never used.
2008-09-09audio: moved cmpAudioFormat() to audio_format.hMax Kellermann
Rename it to audio_format_equals() and return "true" if they are equal.
2008-09-09audio: replaced copyAudioFormat() with simple assignmentMax Kellermann
The "!src" check in copyAudioFormat() used to hide bugs - one should never pass NULL to it. There is one caller which might pass NULL, add a check in this caller. Instead of doing mempcy(), we can simply assign the structures, which looks more natural.
2008-09-08output: static audio_output_plugin list as arrayMax Kellermann
Instead of having to register each output plugin, store them statically in an array. This eliminates the need for the List library here, and saves some small allocations during startup.
2008-09-07audio_format: converted typedef AudioFormat to struct audio_formatMax Kellermann
Get rid of CamelCase, and don't use a typedef, so we can forward-declare it, and unclutter the include dependencies.
2008-09-07audio: don't pass "fd" to printAudioDevices()Max Kellermann
Pass the client struct instead.
2008-09-07audio: don't pass "fd" to {en,dis}ableAudioDevice()Max Kellermann
No protocol code in the audio output library.
2008-09-06include cleanupMax Kellermann
As usual, include only headers which are really needed.
2008-08-29tag: renamed MpdTag and MpdTagItem to struct tag, struct mpd_tag_itemMax Kellermann
Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
2008-08-29pass constant pointersMax Kellermann
And again, convert arguments to const.
2008-08-26moved struct AudioFormat to audio_format.hMax Kellermann
We want to expose the AudioFormat structure to plugins; remove some clutter by moving its declaration to a separate header file.

2008-04-12clean up CPP includesMax Kellermann
Try to only include headers which are really needed. We should particularly check all "headers including other headers". The long-term goal is to have a manageable, small API for plugins (decoders, output) without so many mpd internals cluttering the namespace. git-svn-id: https://svn.musicpd.org/mpd/trunk@7319 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-04-12use size_t in audio.cMax Kellermann
Buffer sizes should be size_t. This is safe here, at least not unsafer than without the patch. I have no idea why audioBufferSize and audioBufferPos were explicitly declared as signed integer. git-svn-id: https://svn.musicpd.org/mpd/trunk@7296 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-04-12moved expression to audioFormatSizeToTime()Max Kellermann
The multi-line expression which calculates sizeToTime is hard to read, partly because "cb->audioFormat." is too long. Create a separate inline function in audio.h for that. git-svn-id: https://svn.musicpd.org/mpd/trunk@7277 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26audio: use a machine word for array sizesMax Kellermann
we do not save anything by limiting a variable to an unsigned char, since the compiler aligns it at machine word size anyway. however by using the full machine word, we save one instruction, and we remove the useless artificial limitation to 255. git-svn-id: https://svn.musicpd.org/mpd/trunk@7203 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong
This will make refactoring features easier, especially now that pthreads support and larger refactorings are on the horizon. Hopefully, this will make porting to other platforms (even non-UNIX-like ones for masochists) easier, too. os_compat.h will house all the #includes for system headers considered to be the "core" of MPD. Headers for optional features will be left to individual source files. git-svn-id: https://svn.musicpd.org/mpd/trunk@7130 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-08-01audio: remove AUDIO_MAX_DEVICES limitEric Wong

2006-07-30interface/connection malloc reductions from mpd-keEric Wong
This patch massively reduces the amount of heap allocations at the interface/command layer. Most commands with minimal output should not allocate memory from the heap at all. Things like repeatedly polling status, currentsong, and volume changes should be faster as a result, and more importantly, not a source of memory fragmentation. These changes should be safe in that there's no way for a remote-client to corrupt memory or otherwise do bad stuff to MPD, but an extra set of eyes to review would be good. Of course there's never any warranty :) No longer do we use FILE * structures in the interface, which means we don't have to allocate any new memory for most connections. Now, before you go on about losing the buffering that FILE * +implies+, remember that myfprintf() never took advantage of any of the stdio buffering features. To reduce the diff and make bugs easier to spot in the diff, I've kept myfprintf in places where we write to files (and not network interfaces). Expect myfprintf to go away entirely soon (we'll use fprintf for writing regular files). git-svn-id: https://svn.musicpd.org/mpd/trunk@4483 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-03-18rewrite statefile code for audio devicesEric Wong
In the words of the original author, it was 'crappy'. I tend to agree :) The code has also been broken for at least the past few months, and nobody bothered fixing it The previous format it was overly complex: 5 lines to describe each device. The new format is one-line per-device: audio_device_state:%d:%s %d - 0 for disabled, any integer for enabled %s - name of the device as specified in the config file, whitespace and all Incompatibilities: * Output names are now _required_ to be unique. This is required because the new format relies solely on the name of the audio device. Relying on the device IDs internal to MPD was a bad idea anyways since the user usually has none or very little idea how they're generated, and adding a new device or removing one from a config would throw things off completely. This is also just a Good Idea(TM) because it makes things less confusing to users when they see it in their clients. * Output states are not preserved from the previous format. Not a big deal, since the previous code was never officially released. Also, it's been broken for months now, so I doubt anybody would notice :) git-svn-id: https://svn.musicpd.org/mpd/trunk@3928 09075e82-0dd4-0310-85a5-a0d7c8717e4f
