2008-09-09audio: replaced copyAudioFormat() with simple assignmentMax Kellermann1-1/+1
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.
2008-09-09output: renamed the functions in output_control.cMax Kellermann1-1/+1
Getting rid of CamcelCase, again.
2008-09-09output: moved code from audioOutput.c to output_control.cMax Kellermann1-117/+1
Similar to decoder_control.c, output_control.c will provide functions for controlling the output thread (which will be implemented later).
2008-09-09output: renamed method namesMax Kellermann1-12/+11
No CamelCase. Also don't declare typedefs for the methods.
2008-09-08output: static audio_output_plugin list as arrayMax Kellermann1-44/+11
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: replace audio_output.*Func with audio_output.pluginMax Kellermann1-17/+11
Instead of copying all that stuff from the audio output plugin to the audio output structure, store a pointer to the plugin.
2008-09-07output: renamed typedef AudioOutput to struct audio_outputMax Kellermann1-15/+16
Also rename AudioOutputPlugin to struct audio_output_plugin, and use forward declarations to reduce include dependencies.
2008-09-07output: added output_api.hMax Kellermann1-0/+1
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 Kellermann1-1/+2
Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
2008-08-29pass constant pointersMax Kellermann1-1/+1
And again, convert arguments to const.
2008-08-26moved struct AudioFormat to audio_format.hMax Kellermann1-0/+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 free()/malloc() instead of realloc()Max Kellermann1-2/+3
When growing the audioOutput->convBuffer, we can use free()+malloc() instead of realloc(), which saves a memcpy(). git-svn-id: https://svn.musicpd.org/mpd/trunk@7295 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2008-04-12use size_t and constant pointer in ao pluginsMax Kellermann1-3/+4
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 Wong1-2/+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

2007-05-26Make pcm_convertAudioFormat return the buffer size. This is necessaryJ. Alexander Treuman1-8/+6
because lsr may return less than the input buffer size, and the rest of the audio code needs to know the new size. This fixes the clicking that was introduced with recent changes to the lsr code. A huge thanks to remiss for figuring this out. git-svn-id: https://svn.musicpd.org/mpd/trunk@6273 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2007-05-24Reverting to the full lsr API. Turns out the simple API needs all of theJ. Alexander Treuman1-4/+6
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

2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-1/+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

Just malloc all of the audioOutput array in one shot to avoid fragmentation and to improve cache locality when iterating through the array.
