2013-12-28pcm/PcmMix: improved ditheringMax Kellermann1-0/+6
Use the existing PcmDither library.

2013-11-06OutputControl: reduce the number of OutputThread wakeupsMax Kellermann1-0/+15
Wake up the OutputThread only if it hasn't already been woken up and if it isn't already in the playback loop.

2013-02-02FilterInternal: convert struct filter to a OO interfaceMax Kellermann1-4/+10
2013-01-15output_internal, ...: add extern "C"Max Kellermann1-0/+8
2012-09-25output: new option "tags" may be used to disable sending tagsMax Kellermann1-0/+7
Implements Mantis ticket 0003340.
2011-09-19output_plugin: the plugin allocates the audio_output objectMax Kellermann1-7/+16
Pass audio_output objects around instead of void pointers. This will give some more control to the plugin, and prepares for non-blocking audio outputs.
2011-09-01output_thread: reimplement CANCEL synchronizationMax Kellermann1-0/+9
The output thread could hang indefinitely after finishing CANCEL, because it could have missed the signal while the output was not unlocked in ao_command_finished(). This patch removes the wait() call after CANCEL, and adds the flag "allow_play" instead. While this flag is set, playback is skipped. With this flag, there will not be any excess wait() call after the pipe has been cleared. This patch fixes a bug that causes mpd to discontinue playback after seeking, due to the race condition described above.
2011-08-30output_control: move code to audio_output_destruct()Max Kellermann1-0/+3
.. and destruct the output object properly in test/run_output.
2011-01-29copyright year 2011Max Kellermann1-1/+1
2011-01-10player_control: removed the global variable "pc"Max Kellermann1-0/+6
Allocate a player_control object where needed, and pass it around. Each "client" object is associated with a "player_control" instance. This prepares multi-player support.
2010-11-04output_internal: protect attribute "fail_timer" with mutexMax Kellermann1-1/+2
2010-05-02output_thread: call replay gain filter manuallyMax Kellermann1-0/+13
Don't add it to the filter chain, because we need to apply replay gain before cross-fading with the next song. Add a second replay_gain filter which is used for the song being faded in (chunk->other).
2010-05-02player_thread: move cross-fading to output threadMax Kellermann1-0/+6
Remove cross_fade_apply(), and call pcm_mix() in the output thread, mixing the chunk and chunk->other together.
2010-03-10output: added option "always_on" for radio stationsMax Kellermann1-0/+6
Did you ever accidently click "stop" while feeding a radio station? This option sets the output device to "pause" to disable the "close" method. It falls back to "pause" then, which is specific to the plugin. Some plugins implement it by feeding silence.
2010-02-17replay_gain: reimplement as a filter pluginMax Kellermann1-0/+12
Apply the replay gain in the output thread. This means a new setting will be active instantly, without going through the whole music pipe. And we might have different replay gain settings for each audio output device.
2009-12-31Update copyright notices.Avuton Olrich1-1/+1
2009-11-09output_thread: added command DRAINMax Kellermann1-0/+7
This command manually drains the hardware buffer. This is useful when the player thread want to make sure that everything has been played.
2009-10-29output: consistently lock audio output objectsMax Kellermann1-6/+8
Always keep the audio_output object locked within the output thread, unless a plugin method is called. This fixes several race conditions.
2009-10-23output_plugin: added methods enable() and disable()Max Kellermann1-0/+8
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.
2009-10-21output: convert config_audio_format to an audio_format structMax Kellermann1-6/+5
This allows more sophisticated audio format selection.
2009-08-14output: fixed shout stuck pause bugMax Kellermann1-0/+6
Explicitly make the output thread leave the ao_pause() loop. This patch is a workaround, and the "pause" flag is not managed in a thread-safe way, but that's good enough for now.
2009-07-06output: attach a filter chain to each audio_outputMax Kellermann1-2/+13
This patch adds initial filter support for audio outputs. Each audio output gets a "filter" attribute, which is used by ao_play_chunk(). The PCM conversion is now performed by convert_filter_plugin. audio_output.convert_state has been removed.
2009-07-06output: added command REOPENMax Kellermann1-0/+7
REOPEN is called when the input audio format changes. The output thread may be reconfigure the PCM converter.
2009-03-26output_plugin: replaced output_plugin.get_mixer() with mixer_pluginMax Kellermann1-0/+7
The mixer core library is now responsible for creating and managing the mixer object. This removes duplicated code from the output plugins.
2009-03-25output: protect audio_output.open with the mutexMax Kellermann1-1/+6
There was a deadlock between the output thread and the player thread: when the output thread failed (and closed itself) while the player thread worked with the audio_output object, MPD could crash.
2009-03-20output: convert audio_output.config_audio_format to booleanMax Kellermann1-6/+6
The config_audio_format used to contain the configured audio format, which is copied to out_audio_format. Let's convert the former to a boolean, which indicates whether out_audio_format was already set. This simplifies some code and saves a few bytes.
2009-03-13all: Update copyright header.Avuton Olrich1-7/+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.
2009-03-09output: play from a music_pipe objectMax Kellermann1-10/+19
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.
2009-02-28output: use GTimer instead of time_t for reopen after failureMax Kellermann1-3/+4
time() is not a monotonic timer, and MPD might get confused by clock skews. clock_gettime() provides a monotonic clock, but is not portable to non-POSIX systems (i.e. Windows). This patch uses GLib's GTimer API, which aims to be portable.
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: include cleanupMax Kellermann1-1/+1
Don't include output_api.h in output_internal.h. This change requires adding missing includes in several sources.
2009-02-16output_api: moved "enum output_command" to output_internal.hMax Kellermann1-0/+11
Now that the output_command enum isn't exposed to output plugins anymore, we can hide its definition within output_internal.h.
2009-02-10output_api: no CamelCase in struct audio_outputMax Kellermann1-6/+6
Renamed audio_output struct members.
2009-02-10output_internal: added missing output_api.h includeMax Kellermann1-0/+1
output_api.h is required for enum audio_output_command.
2009-01-17pcm_convert: return PCM buffer from pcm_convert()Max Kellermann1-2/+0
Removed yet another superfluous buffer layer: return the PCM buffer from pcm_convert() instead of copying PCM data into the caller-supplied buffer.
