* pipe: add helper function music_pipe_empty()Max Kellermann2010-11-051-2/+2
|
* output_all: don't resume playback when stopping during pauseMax Kellermann2009-06-291-2/+0
| | | | | | | | When MPD was paused, and the client sent the "stop" command (or "clear"), a glitch caused MPD to continue playback for a split second. This was because audio_output_all_cancel() calls audio_output_all_update(), which reopens all output devices, and re-ignites the playback loop.
* output_all: explicitly return "true" from audio_output_all_play()Max Kellermann2009-05-291-1/+1
| | | | | | Instead of returning the local variable "ret" which is always true at this point, hard-code the "true" return value, because that might be more readable.
* output_all: synchronize playback with player_control.notifyMax Kellermann2009-03-261-1/+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.
* output_all: synchronize playback with a notify objectMax Kellermann2009-03-251-2/+1
| | | | | | 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().
* output_all: moved code to audio_output_all_wait()Max Kellermann2009-03-251-0/+12
| | | | | | Synchronization with the output thread will be implemented in output_all.c, not in player_thread.c. Currently, that's just a simple g_usleep(1ms).
* output: protect audio_output.open with the mutexMax Kellermann2009-03-251-12/+23
| | | | | | 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.
* output_all: check param!=NULL before accessing itMax Kellermann2009-03-161-2/+7
| | | | | When printing the error message, MPD dereferences the NULL pointer to print an error message if no audio_output section is present.
* output_all: added missing "unused" attributeMax Kellermann2009-03-141-1/+1
| | | | In NDEBUG, clear_tail_chunk() does not use its "chunk" parameter.
* output_all: include chunk.hMax Kellermann2009-03-141-0/+1
| | | | | The source output_all.c accesses music_chunk struct members, but did not include chunk.h directly.
* all: Update copyright header.Avuton Olrich2009-03-131-3/+4
| | | | | | | | 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.
* output_all: fix off-by-one error in audio_output_all_check()Max Kellermann2009-03-121-1/+1
| | | | | | | | When there are chunks which are not yet finished, audio_output_all_check() returned the size of its music pipe minus one. I can't remember exactly why I subtracted 1 from the return value, it must have had something to do with a former meaning of this function. Now it induces assertion failures.
* output_all: clear input_audio_format on closeMax Kellermann2009-03-101-0/+2
| | | | | | When the audio outputs are closed, also clear the audio format. If we don't do this, every call to audio_output_all_update() will open the device, even if it's meant to be paused.
* output_all: don't allow audio_format==NULL in audio_output_all_open()Max Kellermann2009-03-101-5/+3
| | | | | | Don't allow reopening an audio device after pause with audio_format==NULL, force the caller to provide the audio_format each time.
* output: play from a music_pipe objectMax Kellermann2009-03-091-42/+182
| | | | | | | | 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.
* output_all: fix boolean short circuit in update()Max Kellermann2009-03-071-2/+2
| | | | | | | Sometimes, audio_output_update() isn't called for the second device when the first one has succeeded. The patch "audio_output_all_update() returns bool" broke it, because the boolean evaluation ended after the first "true".
* output_all: audio_output_all_update() returns boolMax Kellermann2009-03-071-3/+12
| | | | | audio_output_all_update() returns true when there is at least open output device which is open.
* output_init: return GError on errorMax Kellermann2009-03-011-12/+3
| | | | Do error handling with GError instead of aborting with g_error().
* output: use GTimer instead of time_t for reopen after failureMax Kellermann2009-02-281-2/+8
| | | | | | | 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.
* output_all: print a warning when all outputs are disabledMax Kellermann2009-02-261-1/+7
| | | | | | When all outputs are disabled, MPD printed only a meaningless message "problems opening audio device", although it didn't attempt to open a device.
* output_all: removed "audio_outputs!=NULL" checkMax Kellermann2009-02-261-3/+0
| | | | | After initialization, audio_outputs is always non-NULL. Don't check that.
* output: set a GLib log domainMax Kellermann2009-02-251-0/+3
|
* output: include cleanupMax Kellermann2009-02-161-0/+2
| | | | | Don't include output_api.h in output_internal.h. This change requires adding missing includes in several sources.
* output_all: immediately reopen output on playMax Kellermann2009-02-101-0/+13
| | | | | | | When MPD explicitly starts playing, ignore the "REOPEN_AFTER" timeout. This timeout was useful when MPD attempted to reopen a failed device over and over, but it confuses users when they explicitly tell MPD to start playing, while MPD insists to wait for the 10 seconds to pass.
* output_all: moved code to audio_output_all_finished()Max Kellermann2009-02-101-13/+16
| | | | audio_output_all_finished() returns bool, not int.
* output_all: no CamelCaseMax Kellermann2009-02-101-58/+66
| | | | Renamed functions and variables.
* audio: moved code to output_all.cMax Kellermann2009-02-101-0/+270
Moved code which deals with all audio outputs at once into a separate library.
