Now "-ao openal:device=<subdevice>" will pass <subdevice> as device to
OpenAL. This allows selecting both the OpenAL backend (OS-level audio
API) and the physical output device.
The available devices can be listed with "-ao openal:device=help".
The recent changes in mixer.c require the AO to return a volume of
exactly 0 when audio has been muted. Rather than adding just another
special case to mixer.c, fix ao_dsound.c to return previously set
volumes exactly. Because DirectSound volume control is not connected
with the system mixer, which could change the volume without mplayer
knowing, reading the volume back from DirectSound is pointless.
Also, the code tried to calculate log10(0). Clip the volume to 1,
which results in -10000, DirectSound's definition of silence.
When layback of a file ends, the audio output doesn't receive new audio
data, but the rest of the data must be played properly. ao_dsound.c
doesn't handle this properly: DirectSound will continue to play the
ringbuffer, even if mplayer doesn't write any data. There's no explicit
way to prevent such a buffer underrun. Try to detect it and stop
playback.
Some of the code, especially the dshow and windows codec loader parts,
are extremely hacky and likely full of bugs. The goal is merely getting
rid of warnings that could obscure more important warnings and actual
bugs, instead of fixing actual problems. This reduces the number of
warnings from over 500 to almost the same as when compiling on Linux.
Note that many problems stem from using the ancient wine-derived
windows headers. There are some differences to the "proper" windows
header. Changing the code to compile with the proper headers would be
too much trouble, and it still has to work on Unix.
Some of the changes might actually break compilation on legacy MinGW,
but we don't support that anymore. Always use MinGW-w64, even when
compiling to 32 bit.
Fixes some warnings in the win32 loader code on Linux too.
If digital pass-through is used, this supported setting the volume (just
mute, actually), but not getting the volume. This will probably lead to a
stuck mute state in the mplayer frontend. Make the code respond to volume
queries even if digital pass-through is used.
Ideally, ao_coreaudio should implement full mute control, but I can't
even test on OSX.
The mixer frontend code can now make use of a proper system mixer mute
toggle, if the audio output driver supports it.
The consequence is that, if support is available, mplayer will no longer
temporarily set the system volume to 0 if mute is enabled.
Generally, the code now deals with the following combinations of available
AO features:
- software volume control forced by user (--softvol / soft_vol flag)
=> if enabled, never touch the "hardware" controls
- "hardware"/driver volume control available (whether
AOCONTROL_GET/SET_VOLUME works)
=> if not available, enable volume controls by enabling softvol
- "hardware"/driver mute control (AOCONTROL_GET/SET_MUTE)
=> if not available, emulate by setting volume to 0
- whether the volume+mute controls are kept or not when the AO is closed
(indicated by ao->no_persistent_volume)
=> if not persistent, restore the volume/mute next time the AO is opened
The mplayer frontend (specifically, mixer.c) needs to know this. If the
audio output doesn't remember the volume across reinitialization, the
frontend will restore the volume settings. There is also the assumption
that the volume setting isn't global in this case (i.e. changing it
won't change the volume of other applications or annoy the user
otherwise).
None of these changes have been tested. I'm guessing that ESD and NAS do
per-connection non-persistent volume settings.
Some audio outputs don't provide access to a system-wide mixer control, and
do per-application audio mixing. Further, some of these forget the volume
as soon as the audio device is closed. This can be annoying, because
mplayer will "forget" the volume when playing a new file or when crossing
ordered chapter boundaries. Support restoring the volume on audio
reinitialization if an audio output driver knowingly behaves this way.
(This doesn't change that mplayer never writes any settings into the config
file, including volume settings.)
This commit doesn't yet change any actual output driver to use this code.
Hopefully make some logic in the volume restore code a bit more robust.
Now PulseAudio is preferred over ALSA, which in turn is preferred over
OSS. This should give best results on all systems. On systems with
PulseAudio, we will always use it natively, rather than through the
suboptimal ALSA emulation (which the default ALSA output is normally
redirected to when PulseAudio is active; ALSA hardware devices will
not be, but to use those the user must set AO explicitly in any case,
so changing the defaults makes no difference). The fallback from
ao_pulse to ao_alsa causes no noticeable delay on systems without
PulseAudio. On systems with ALSA, we won't attempt to use OSS anymore.
Also, move OpenAL above SDL. OpenAL should generally work better than
SDL.
RenderCallbackSPDIF might call read_buffer with NULL data. The purpose
is to drain data from the buffer when the output is muted. Add a check
to call av_fifo_drain() in this case.

The variable corresponding to the "fast" suboption of ao_pcm was
uninitialized. Fix. The only effect was possibly printing a warning
about the suboption being deprecated even if it wasn't used.
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.
On MinGW64 io.h is needed for _get_osfhandle().

If opening an audio output driver using the old API failed the
"global_ao" variable was not set back to NULL as it should have been.
This caused an assert failure the next time there was an attempt to
open such an AO (either due to fallback to another AO after the
failure or after moving to another file). Fix.
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.
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.
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.
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.
dxr2 support had been broken quite a while and nobody noticed. There
were finally commits to fix it in the svn repo, but rather than apply
those I'll just drop dxr2 support.
This version is the last OS version available for certain classes of
PPC Macs, but it lacks AudioDeviceIOProcID, so it has to be emulated.

-novideo is the right way to disable video, and should also work in
more cases now that lavf is used as the default demuxer for more formats
(like AVI; internal AVI demuxer fails with -novideo).
Also change the man page description of -novideo a bit to make it
sound less negative about the chances of the option working.
Reportedly this also fixes a possible hang at the end of playback
(shouldn't happen unless delay reporting is broken too).
