[MPlayer-users] a52: no resampler. try different channel setup!

[Brent Roman]

Great player!

I've got a couple DVD's which are encoded with monophonic audio
(believe it or not)

mplayer's audio configuration seems to choke on them.

In the output below, not the following lines:

AC3: 1.0 (mono)  48000 Hz  192.0 kbit/s
Unimplemented resampler for mode 0x1 -> 1 channels conversion - Contact
MPlayer developers!
a52: no resampler. try different channel setup!
Couldn't initialize audio codec! -> nosound

Peeking at the function a52_resample_MMX in resample_mmx.c,
it looks like the A52_MONO flag is set, which means that the
only resampler available requires five output channels.

I've tried added the "-channels n" option where n=2..6
to no avail.

Is this just a missing case in a52_resample_MMX?

Thanks in Advance,
