[MEncoder-users] Garbled sound while transcoding a video

[Akshat Aranya]

Hi,

I'm trying to use mencoder on Ubuntu Feisty to transcode videos. The
video gets transformed OK but the audio is completely garbled. This
happens no matter what kind of audio output I choose -- I've tried
faac and mp3lame. The only way the audio is okay is if I just use the
"-oac copy" option. Also, it does not matter what kind of video I try
to transcode. Here's the command line that I'm using:

mencoder a.avi -o b.avi -srate 44100 -oac mp3lame -lameopts
vbr=0;br=96 -ovc lavc -lavcopts vcodec:mpeg4:vbitrate=96 -vf-add crop
586:352 -vf=add scale=240:144 -ofps 12.5 -ffourcc DIVX -noidx
-force-avi-aspect 1.6666667


mencoder version 2:1.0~rc1-0ubuntu9
liblame0 version 3.96.1-2ubuntu1

This problem is only happening on one of my machines.  I have another
machine that is also running Feisty and it is able to transcode
properly with the same parameters.

Any ideas?
