* mixer: support native audio driver muteUoti Urpala2012-04-111-0/+3
| | | | | | | | | | | | | Make mixer support setting the mute attribute at audio driver level, if one exists separately from volume. As of this commit, no libao2 driver exposes such an attribute yet; that will be added in later commits. Since the mute status can now be set externally, it's no longer completely obvious when the player should automatically disable mute when uninitializing an audio output. The implemented behavior is to turn mute off at uninitialization if we turned it on and haven't noticed it turn off (by external means) since.
* audio: restore volume setting after AO reinit if neededUoti Urpala2012-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | MPlayer volume control was originally implemented with the assumption that it controls a system-wide volume setting which keeps its value even if a process closes and reopens the audio device. However, this is not actually true for --softvol mode or some audio output APIs that only consider volume as a per-client setting for software mixing. This could have annoying results, as the volume would be reset to a default value if the AO was closed and reopened, for example whem moving to a new file or crossing ordered chapter boundaries. Add code to set the previous volume again after audio reinitialization if the current audio chain is known to behave this way (softvol active or the AO driver is known to not keep persistent volume externally). This also avoids an inconsistency with the mute flag. The frontend assumed the mute status is persistent across file changes, but it could be similarly lost. The audio drivers that are assumed to not keep persistent volume are: coreaudio, dsound, esd, nas, openal, sdl. None of these changes have been tested. I'm guessing that ESD and NAS do per-connection non-persistent volume settings. Partially based on code by wm4.
* libao2: change control() types to enum, remove unused onesUoti Urpala2012-04-081-25/+24
| | | | | | | | | Change the audio driver control() command argument from "int" to "enum aocontrol". Remove unused control types (SET_DEVICE, GET_DEVICE, QUERY_FORMAT, SET_PLUGIN_DRIVER, SET_PLUGIN_LIST). The QUERY_FORMAT one looks like there's a possibility such functionality could be useful in the future, but as ao_oss was the only driver to have an actual implementation of it, the current code wasn't worth keeping.
* ao_pulse, core: make pulse thread wake up core for more dataUoti Urpala2012-03-261-1/+2
| | | | | | | | | | | | | | | For ao_pulse, the current latency is not a good indicator of how soon the AO requires new data to avoid underflow. Add an internal pipe that can be used to wake up the input loop from select(), and make the pulseaudio main loop (which runs in a separate thread) use this mechanism when pulse requests more data. The wakeup signal currently contains no information about the reason for the wakup, but audio buffers are always filled when the event loop wakes up. Also, request a latency of 1 second from the Pulseaudio server. The default is normally significantly higher. We don't need low latency, while higher latency helps prevent underflows reduces need for wakeups.

* audio: export audio pts to AO driversUoti Urpala2011-07-311-1/+2
| | | | | Currently the pts value is not directly used by any AO. Will be used by encoding code.
* audio: move ready-for-ao data buffer from decoder to AOUoti Urpala2011-07-021-0/+4
| | | | | | | | | | | | Move the buffer storing audio data ready to be fed to the audio output driver from the audio decoder object to the AO object. This will help encoding code deal with end of input, and may also be useful to improve other general gapless audio behavior (as AOs which do not accept chunks smaller than a certain size may keep them in the buffer while the decoder changes). Less data may be dropped now when changing audio filters or switching timeline parts.
* ao_pcm, core: use new API in ao_pcm, change timing with itUoti Urpala2011-05-051-0/+1
| | | | | | | | | | | | | | | | | Change ao_pcm to use the new audio output driver API and clean up some of the code. Rewrite the logic controlling how playback timing works when using -ao pcm. Deprecate the "fast" suboption; its only effect now is to print a warning, but it's still accepted so that specifying it is not an error. Before, timing with -ao pcm and video enabled had two possible modes. In the default mode playback speed was rather arbitrary - not realtime, but not particularly fast. -ao pcm:fast tried to play back at maximum video playback speed - mostly succeeding, but not quite guaranteed to work in all cases. Now the default is to play at realtime speed. The -benchmark option can now be used to get faster playback (same as the video-only case). In the audio-only case playback is always maximum speed.
* audio output: add a new AO driver APIUoti Urpala2011-05-051-4/+31
| | | | | | | Add a new audio output driver API. The main change is the addition of a context struct where data can be kept instead of using globals. The old API remains available. This commit does not yet convert any driver to use the new API.
* cleanup: reindent audio_out.[ch]Uoti Urpala2011-05-041-35/+30
| | | | | | Reindent audio_out.c and audio_out.h. Also remove trailing '_s' from two struct names (which are not currently used anywhere) and make the audio_out_drivers[] table static.
* audio: change external AO interface to "ao_[method](ao, ...)"Uoti Urpala2011-04-091-5/+18
| | | | | | | | Make the outside interface of audio output handling similar to the video output one. An AO object is first created, and then methods called with ao_[methodname](ao, args...). However internally libao2/ still holds all data in globals, and trying to create multiple simultaneous AO instances won't work.

* Patch by Stefan Huehner / stefan % huehner ! org \rathann2006-02-091-6/+6
| | | | | | | | | | | | | | | | | | | | | | patch replaces '()' for the correct '(void)' in function declarations/prototypes which have no parameters. The '()' syntax tell thats there is a variable list of arguments, so that the compiler cannot check this. The extra CFLAG '-Wstrict-declarations' shows those cases. Comments about a similar patch applied to ffmpeg: That in C++ these mean the same, but in ANSI C the semantics are different; function() is an (obsolete) K&R C style forward declaration, it basically means that the function can have any number and any types of parameters, effectively completely preventing the compiler from doing any sort of type checking. -- Erik Slagter Defining functions with unspecified arguments is allowed but bad. With arguments unspecified the compiler can't report an error/warning if the function is called with incorrect arguments. -- Måns Rullgård git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@17567 b3059339-0415-0410-9bf9-f77b7e298cf2
