Hi all,
I want to re-encode a video with mencoder (let's say stereo.avi [xvid+mp3]) so that sound becomes mono.
That's what I do:
mencoder stereo.avi -ovc copy -oac mp3lame -lameopts cbr:br=128:mode=3 -o mono.avi
Ok, this doesn't work, this still has 2 channels.
I've also tried the following:
mencoder stereo.avi -ovc copy -oac mp3lame -lameopts cbr:br=128:mode=3 -af pan=1:0.5:0.5 -channels 1 -o mono.avi
That also doesn't work 
What am I doing wrong?
Any help is appreciated, thx a lot.

Try ffmpeg instead, a little easier imho:
ffmpeg -i stereo.avi -vcodec copy -acodec mp3 -ac 1 -ab 128 mono.avi

Hi, thx for your answer.
Does ffmpeg use lame for encoding mp3?
Anyway, I'd like to do it with mencoder so if anyone knows how to do it i'll be very happy if u post.
Thank you.
