2010-05-02output_thread: call replay gain filter manuallyMax Kellermann1-15/+57
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/+30
Remove cross_fade_apply(), and call pcm_mix() in the output thread, mixing the chunk and chunk->other together.
2010-05-02output_thread: moved code to ao_filter_open(), ao_filter_close()Max Kellermann1-7/+19
2010-05-02output_thread: moved filter invocation to ao_filter_chunk()Max Kellermann1-16/+52
2010-02-17replay_gain: optionally use hardware mixer to apply replay gainMax Kellermann1-1/+2
Add an option for each audio output which enables the use of the hardware mixer, instead of the software volume code. This is hardware specific, and assumes linear volume control. This is not the case for hardware mixers which were tested, making this patch somewhat useless, but we will use it to experiment with the settings, to find a good solution.
2010-02-17replay_gain: reimplement as a filter pluginMax Kellermann1-0/+11
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
2009-11-14audio_format: added function audio_format_to_string()Max Kellermann1-10/+6
Unified function for converting an audio_format object to a string, for log messages and for the "status" command.
2009-11-12include config.h in all sourcesMax Kellermann1-0/+1
After we've been hit by Large File Support problems several times in the past week (which only occur on 32 bit platforms, which I don't have), this is yet another attempt to fix the issue.
2009-11-09output_thread: added command DRAINMax Kellermann1-0/+13
This command manually drains the hardware buffer. This is useful when the player thread want to make sure that everything has been played.
2009-11-02output_thread: moved code to ao_next_chunk()Max Kellermann1-6/+11
2009-11-02output_thread: return from ao_play() if chunk->next is NULLMax Kellermann1-5/+4
When the "next" chunk to be played is NULL, return from ao_play() immediately, without going over the "while" loop (no-op).
2009-11-02output_thread: check command before g_cond_wait()Max Kellermann1-1/+2
After CANCEL, call g_cond_wait() only if the new command is still NONE. Problem is that ao_command_finished() has to unlock the audio_output object, and in the meantime, the player thread might have submitted a new command.
2009-10-31player_control: protect command, state, error with a mutexMax Kellermann1-1/+1
Use GMutex/GCond instead of the notify library. Manually lock the player_control object before accessing the protected attributes. Use the GCond object to notify the player thread and the main thread.
2009-10-29output_thread: return bool from ao_play()Max Kellermann1-4/+22
Return false when there was no chunk in the pipe. If the function returns true, then audio_output_task() will not wait for a notify from the player thread. This fixes a race condition.
2009-10-29output: consistently lock audio output objectsMax Kellermann1-16/+39
Always keep the audio_output object locked within the output thread, unless a plugin method is called. This fixes several race conditions.
2009-10-29output_plugin: added method "drain"Max Kellermann1-11/+13
drain() is the opposite of cancel(): it waits until all data in the buffer has finished playing. Instead of implicitly draining in the close() method like the ALSA plugin has been doing it forever, let the output thread decide whether to drain or to cancel.
2009-10-29output_thread: removed redundant filter_close() callMax Kellermann1-4/+0
Don't call filter_close() right after ao_close().
2009-10-23output_plugin: added methods enable() and disable()Max Kellermann1-0/+50
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.
2009-10-21audio_format: wildcards allowed in audio_format configurationMax Kellermann1-5/+6
An asterisk means that this attribute should not be enforced, and stays whatever it used to be. This way, some configuration values work like masks.
2009-10-21output: convert config_audio_format to an audio_format structMax Kellermann1-2/+4
This allows more sophisticated audio format selection.
2009-10-21output_thread: check again if output is open on PAUSEMax Kellermann1-0/+9
Basically the same as the 0.15.5 patch "check again if output is open on CANCEL". Same race condition, same fix.
2009-10-16output_thread: check again if output is open on CANCELMax Kellermann1-1/+2
When the player thread unpauses, it sends CANCEL to the output thread, after having checked that the output is still open. Problem is when the output thread closes the device before it can process the CANCEL command - race condition. This patch adds another "open" check inside the output thread.
2009-08-14output: fixed shout stuck pause bugMax Kellermann1-0/+3
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.
2009-07-19Add reverse_endian field to struct audio_format and handle conversionDavid Woodhouse1-4/+6
2009-07-06output: attach a filter chain to each audio_outputMax Kellermann1-15/+77
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/+25
REOPEN is called when the input audio format changes. The output thread may be reconfigure the PCM converter.
2009-07-06output_thread: moved OPEN handler to ao_open()Max Kellermann1-43/+48
2009-06-29output_thread: don't play next chunk after command==PAUSEMax Kellermann1-1/+5
When the PAUSE loop ends, re-check the next command before calling ao_play() again.
2009-03-26output_all: synchronize playback with player_control.notifyMax Kellermann1-1/+2
This patch fixes a longer delay when moving around songs in the playlist. The main thread wants to enqueue a new "next" song into the player thread, but the player thread is waiting inside audio_output_all_wait() for the output threads. Use player_control.notify there, so audio_output_all_wait() gets woken up by the main thread, too.
2009-03-25output_all: synchronize playback with a notify objectMax Kellermann1-0/+2
Use audio_output_client_notify instead of g_usleep(1ms) in audio_output_all_wait() to synchronize with the output_thread. Signal the audio_output_client_notify object in ao_play().
2009-03-25output: protect audio_output.open with the mutexMax Kellermann1-2/+4
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.
2009-03-13all: 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_thread: check commands while playingMax Kellermann1-1/+1
Check audio_output.command after each sub-chunk has been played. It discards the rest of the chunk, but since all commands make the device stop anyway, this is not a problem, but part of the improvement. This improves the latency of audio output commands.
2009-03-09output: play from a music_pipe objectMax Kellermann1-17/+80
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_thread: wait 10 seconds before reopening after play failureMax Kellermann1-0/+4
This is similar to the MPD 0.14 patch "wait 10 seconds before reopening a failed device", which only covered open() failures. This patch adds the same feature for play().
2009-03-08output_thread: print "closed" debug messageMax Kellermann1-0/+2
2009-03-01output_thread: log audio format in a debug messageMax Kellermann1-0/+16
To aid debugging, print the audio format of the output plugin in a debug message, and print information about PCM conversion.
2009-02-28output: use GTimer instead of time_t for reopen after failureMax Kellermann1-7/+2
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.
2009-02-26output_plugin: report errors with GErrorMax Kellermann1-3/+18
Use GLib's GError library for reporting output device failures. Note that some init() methods don't clean up properly after a failure, but that's ok for now, because the MPD core will abort anyway.
2009-02-26output_thread: use the right audio_format in assert()Max Kellermann1-1/+1
ao_play() gets PCM data in the in_audio_format, and converts it to out_audio_format. Comparing the input data with out_audio_format is wrong. prefixed with "STG:" will be automatically removed. STG: Trailing empty lines will be automatically removed. STG: vi: set textwidth=75 filetype=diff nobackup:
2009-02-25output: set a GLib log domainMax Kellermann1-0/+4
2009-02-23output_api: play() returns a lengthMax Kellermann1-5/+17
The old API required an output plugin to not return until all data passed to the play() method is consumed. Some output plugins have to loop to fulfill that requirement, and may block during that. Simplify these, by letting them consume only part of the buffer: make play() return the length of the consumed data.
2009-02-16output_plugin: added inline wrapper functionsMax Kellermann1-28/+20
Similar to the decoder plugin API: added wrapper functions to increase code readability.
2009-02-10output_thread: moved code to ao_close()Max Kellermann1-12/+14
Merge some duplicate code into one function.
2009-02-10output_thread: leave the pause loop on failureMax Kellermann1-0/+1
When the pause() method fails, leave the pause loop, because calling pause() on a closed device is not allowed.
2009-02-10output_thread: consistently (de)initialize pcm_convert_stateMax Kellermann1-3/+5
Fix a memory leak: it was not guaranteed that pcm_convert_deinit() was called for each pcm_convert_init(). This patch always (de)initializes the pcm_convert library when the audio_output.open flag is flipped.
2009-02-10output_api: no CamelCase in struct audio_outputMax Kellermann1-8/+8
Renamed audio_output struct members.
2009-01-30output_api: moved the command check out of method pause()Max Kellermann1-1/+11
Move the "while" loop which checks for commands to the caller ao_pause(). This simplifies the pause() method, and lets us remove audio_output_is_pending().
2009-01-17pcm_convert: return PCM buffer from pcm_convert()Max Kellermann1-25/+4
Removed yet another superfluous buffer layer: return the PCM buffer from pcm_convert() instead of copying PCM data into the caller-supplied buffer.
