2009-10-23output_plugin: added methods enable() and disable()Max Kellermann1-0/+12
With these methods, an output plugin can allocate some global resources only if it is actually enabled. The method enable() is called after daemonization, which allows for more sophisticated resource allocation during that method.
2009-10-20output_init: renamed parameter "error" to "error_r"Max Kellermann1-1/+1
It's a double pointer.
2009-03-13all: Update copyright header.Avuton Olrich1-6/+7
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.
2009-03-10output_control: removed audio_output_signal()Max Kellermann1-8/+0
This function was part of a workaround which we don't need anymore.
2009-03-09output: play from a music_pipe objectMax Kellermann1-5/+4
Instead of passing individual buffers to audio_output_all_play(), pass music_chunk objects. Append all those chunks asynchronously to a music_pipe instance. All output threads may then read chunks from this pipe. This reduces MPD's internal latency by an order of magnitude.
2009-03-09output_control: make audio_output_open() staticMax Kellermann1-4/+0
audio_output_open() is only called by audio_output_update(). Don't export it.
2009-03-07output_all: audio_output_all_update() returns boolMax Kellermann1-1/+3
audio_output_all_update() returns true when there is at least open output device which is open.
2009-03-01output_init: return GError on errorMax Kellermann1-1/+10
Do error handling with GError instead of aborting with g_error().
2009-02-25output: audio_output_init() returns boolMax Kellermann1-1/+1
Return true/false instead of 1/0.
2009-02-23output: pass the music chunk pointer as void*, not char*Max Kellermann1-1/+1
The meaning of the chunk depends on the audio format; don't suggest a specific format by declaring the pointer as "char*", pass "void*" instead.
2009-02-16output_control: no CamelCaseMax Kellermann1-12/+11
Renamed variables.
2009-01-25conf: const pointers in block get functionsMax Kellermann1-1/+1
All config_get_block_*() functions should accept constant config_param pointers.
2009-01-18output: don't include conf.h from output_control.hMax Kellermann1-2/+1
Minimize header dependencies.
2009-01-17conf: no CamelCase, part IMax Kellermann1-1/+2
Renamed functions, types, variables.
2008-10-31added prefix to header macrosMax Kellermann1-2/+2
"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: moved code to audio_output_update()Max Kellermann1-0/+7
Moved code from syncAudioDeviceStates() to audio_output_update().
2008-10-29output: use bool for return values and flagsMax Kellermann1-2/+5
Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
2008-10-08don't include os_compat.hMax Kellermann1-1/+2
When there are standardized headers, use these instead of the bloated os_compat.h.
2008-09-29audio_output: added method pause()Max Kellermann1-0/+3
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.
2008-09-26audio_output: workaround for deadlockMax Kellermann1-0/+9
During debugging, I found a deadlock between flushAudioBuffer() and the audio_output_task(): audio_output_task() didn't notice that there is a command, and flushAudioBuffer() waited forever in notify_wait(). I am not sure yet what is the real cause; work around this for now by waking up non-finished audio outputs in every iteration.
2008-09-24output: semi-asynchronous playbackMax Kellermann1-2/+2
Send an output buffer to all output plugins at the same time, instead of waiting for each of them separately. Make several functions non-blocking, and introduce the new function audio_output_wait_all() to synchronize with all audio output threads.
2008-09-09output: renamed the functions in output_control.cMax Kellermann1-10/+10
Getting rid of CamcelCase, again.
2008-09-09output: moved code from audioOutput.c to output_control.cMax Kellermann1-6/+2
Similar to decoder_control.c, output_control.c will provide functions for controlling the output thread (which will be implemented later).
2008-09-09output: removed keepAudioOutputAlive() declarationMax Kellermann1-1/+0
This function is declared, but is neither used nor implemented.
2008-09-08output: static audio_output_plugin list as arrayMax Kellermann1-17/+0
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.
2008-09-07output: renamed typedef AudioOutput to struct audio_outputMax Kellermann1-21/+22
Also rename AudioOutputPlugin to struct audio_output_plugin, and use forward declarations to reduce include dependencies.
2008-09-07output: added output_api.hMax Kellermann1-64/+3
Just like decoder_api.h, output_api.h provides the audio output API which is used by the plugins.
2008-09-07audio_format: converted typedef AudioFormat to struct audio_formatMax Kellermann1-4/+4
Get rid of CamelCase, and don't use a typedef, so we can forward-declare it, and unclutter the include dependencies.
2008-08-29tag: renamed MpdTag and MpdTagItem to struct tag, struct mpd_tag_itemMax Kellermann1-2/+3
Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
2008-08-29pass constant pointersMax Kellermann1-2/+2
And again, convert arguments to const.
2008-08-26moved struct AudioFormat to audio_format.hMax Kellermann1-1/+1
We want to expose the AudioFormat structure to plugins; remove some clutter by moving its declaration to a separate header file.

2008-04-12use size_t and constant pointer in ao pluginsMax Kellermann1-2/+3
The audio output plugins should get a constant pointer, because they must not modify the buffer. Since the size is a non-negative buffer size in bytes, we should change its type to size_t. git-svn-id: https://svn.musicpd.org/mpd/trunk@7293 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-0/+1
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
2007-06-13Adding FIFO audio output. This is pretty much identical to the old one,J. Alexander Treuman1-0/+1
except that it now uses a timer for throttling. git-svn-id: https://svn.musicpd.org/mpd/trunk@6621 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2007-06-12Load shout first instead of last. This makes it more likely to block otherJ. Alexander Treuman1-1/+1
outputs, which is actually desired behaviour. This way if the shout server takes a while to respond, the shout output can block until connected without messing up other audio outputs. git-svn-id: https://svn.musicpd.org/mpd/trunk@6554 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-05-24Reverting to the full lsr API. Turns out the simple API needs all of theJ. Alexander Treuman1-0/+2
audio at once, so it won't work for us. The old full API code was still heavily broken, as each call to pcm_convertSampleRate() used the same state, even if it was processing two streams of audio. The new code keeps a separate state for each audio stream that's being converted. git-svn-id: https://svn.musicpd.org/mpd/trunk@6255 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-12/+1
Some compilers and linkers aren't smart enough to optimize this, as global variables are implictly initialized to zero. As a result, binaries are a bit smaller as more goes in the .bss and less in the text section. git-svn-id: https://svn.musicpd.org/mpd/trunk@5254 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-0/+1
I'm checking for zero-size allocations and assert()-ing them, so we can more easily get backtraces and debug problems, but we'll also allow -DNDEBUG people to live on the edge if they wish. We do not rely on errno when checking for OOM errors because some implementations of malloc do not set it, and malloc is commonly overridden by userspace wrappers. I've spent some time looking through the source and didn't find any obvious places where we would explicitly allocate 0 bytes, so we shouldn't trip any of those assertions. We also avoid allocating zero bytes because C libraries don't handle this consistently (some return NULL, some not); and it's dangerous either way. git-svn-id: https://svn.musicpd.org/mpd/trunk@4690 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-08-01audio: malloc reductionsEric Wong1-1/+1
Just malloc all of the audioOutput array in one shot to avoid fragmentation and to improve cache locality when iterating through the array. We also know name and type members of the AudioOutput struct won't change in the config, so there's no need to strdup them. newAudioOutput => initAudioOutput git-svn-id: https://svn.musicpd.org/mpd/trunk@4515 09075e82-0dd4-0310-85a5-a0d7c8717e4f
