[MEncoder-users] manipulating audio channels on a VOB file

[Davide Dozza]

Hi all,

I've a self-produced DVD with a video and a stereo audio stream.

On the stereo audio stream I would like to overwrite the right audio
channel with the left one.

By playing a vob file in this way

mplayer VTS_01_2.VOB -af channels=2:2:0:1:0:0

the result is perfect.
But when I try to use mencoder in this way

mencoder VTS_01_2.VOB -ovc copy -oac copy -af channels=2:2:0:1:0:0 -o
pippo.vob

it doesn't produce what I expect.

Any suggestion about?

Davide
