About a year ago, ubitux converted most of the old manpage from the
hard to maintain nroff format to reStructuredText. This was not merged
back into the master repository immediately. The argument was that the
new manpage still required work to be done. However, progress was very
slow. Even worse: the old manpage wasn't updated, because it was
scheduled for deletion, and updating it would have meant useless work.
Now the situation is that the new manpage still isn't finished, and the
old manpage is grossly out of sync with the player. This is not helpful
for users. Additionally, keeping the new manpage in a separate branch,
while the normal development repository for code had the old manpage,
was very inconvenient, because you couldn't just update the
documentation in the same commit as the code.
Even though the new manpage isn't finished yet, merging it now seems to
be the best course of action. Squash-merge the manpage development
branch [1], revision e89f5dd3f2, which branches from the mplayer2
master branch after revision 159102e0cb.
Committers:
* Clément Bœsch <ubitux@gmail.com> (Initial conversion to RST.)
* Uoti Urpala <uau@mplayer2.org> (Many updates.)
* Myself (Minor edits.)
Most text of the manpage has been directly taken from the old manpage,
because this is a conversion, not a complete rewrite.

AUDIO OUTPUT DRIVERS
|
|
====================
|
|
|
|
Audio output drivers are interfaces to different audio output facilities. The
|
|
syntax is:
|
|
|
|
--ao=<driver1[:suboption1[=value]:...],driver2,...[,]>
|
|
Specify a priority list of audio output drivers to be used.
|
|
|
|
If the list has a trailing ',' MPlayer will fall back on drivers not contained
|
|
in the list. Suboptions are optional and can mostly be omitted.
|
|
|
|
*NOTE*: See ``--ao=help`` for a list of compiled-in audio output drivers.
|
|
|
|
*EXAMPLE*:
|
|
|
|
- ``--ao=alsa,oss,`` Try the ALSA driver, then the OSS driver, then others.
|
|
- ``--ao=alsa:noblock:device=hw=0.3`` Sets noblock-mode and the device-name
|
|
as first card, fourth device.
|
|
|
|
Available audio output drivers are:
|
|
|
|
alsa
|
|
ALSA 0.9/1.x audio output driver
|
|
|
|
noblock
|
|
Sets noblock-mode.
|
|
device=<device>
|
|
Sets the device name. Replace any ',' with '.' and any ':' with '=' in
|
|
the ALSA device name. For hwac3 output via S/PDIF, use an "iec958" or
|
|
"spdif" device, unless you really know how to set it correctly.
|
|
|
|
alsa5
|
|
ALSA 0.5 audio output driver
|
|
|
|
oss
|
|
OSS audio output driver
|
|
|
|
<dsp-device>
|
|
Sets the audio output device (default: ``/dev/dsp``).
|
|
<mixer-device>
|
|
Sets the audio mixer device (default: ``/dev/mixer``).
|
|
<mixer-channel>
|
|
Sets the audio mixer channel (default: pcm).
|
|
|
|
sdl (SDL only)
|
|
highly platform independent SDL (Simple Directmedia Layer) library audio
|
|
output driver
|
|
|
|
<driver>
|
|
Explicitly choose the SDL audio driver to use (default: let SDL
|
|
choose).
|
|
|
|
jack
|
|
audio output through JACK (Jack Audio Connection Kit)
|
|
|
|
port=<name>
|
|
Connects to the ports with the given name (default: physical ports).
|
|
name=<client
|
|
Client name that is passed to JACK (default: MPlayer [<PID>]). Useful
|
|
if you want to have certain connections established automatically.
|
|
(no-)estimate
|
|
Estimate the audio delay, supposed to make the video playback smoother
|
|
(default: enabled).
|
|
(no-)autostart
|
|
Automatically start jackd if necessary (default: disabled). Note that
|
|
this seems unreliable and will spam stdout with server messages.
|
|
|
|
nas
|
|
audio output through NAS
|
|
|
|
coreaudio (Mac OS X only)
|
|
native Mac OS X audio output driver
|
|
|
|
device_id=<id>
|
|
ID of output device to use (0 = default device)
|
|
help
|
|
List all available output devices with their IDs.
|
|
|
|

|
|
|
pulse

|
PulseAudio audio output driver
|
|
|
|
[<host>][:<output sink>]
|
|
Specify the host and optionally output sink to use. An empty <host>
|
|
string uses a local connection, "localhost" uses network transfer
|
|
(most likely not what you want).
|
|
|
|
sun (Sun only)
|
|
native Sun audio output driver
|
|
|
|
<device>

|
|
list of available devices.
|
|
|
|
ivtv (IVTV only)
|
|
IVTV specific MPEG audio output driver. Works with ``--ac=hwmpa`` only.
|

|
|
file if no DVB card is installed.

|
raw PCM/wave file writer audio output
