[MPlayer-users] debian wmv Video used to play but Doesn't now.

[Martin McCormick]

	I have a file that I first acquired in 2006 called
kosovo.wmv.  At that time, mplayer would play the sound with no
trouble but it seems that no matter what I set in
~/.mplayer/config, there is no audio.  An example of the messages
from mplayer follows:

$mplayer -quiet ~/videos/kosovo.wmv

Exiting... (End of file)

	The ~/.mplayer/config file is set as follows:

# Write your default config options here!
lirc=NO
joystick=NO
vc=null 
vo=null
#ao=oss
ao=alsa

	If I take out
ao=alsa and replace that with ao=oss, we get pretty much the same
results except that the mute playback appears to either never end
and lasts far longer than the video normally runs.

	When run without the -quiet flag, it prints the progress
indicator and that indicator stops counting when one presses the
Space bar and resumes counting on the next press but that's all.
The -quiet session using ao=oss produces the following:

Exiting... (Quit)

The exit occurred after typing q.

ao=oss seems to cause it to attempt to play nothing forever but
the alsa driver causes the attempt to play to last about as long
as a proper play of that video should run.

	Any constructive suggestions are welcome.  The file in
question is listed on youtube.  It is a good test file to see if
one can play the sound from an older .wmv file and, so far, one
can't although it used to play with no issues.
