[MPlayer-users] mencoder problem

[Robert Zelic]

There is a delay in sound when I encode from raw video material.

I've tried with -audio-delay -0.026, and there is a little improvement, but its not 
that I want. Audio delay is 0.026s for every video file.


The same happens with -ovc lavc, but there is no delay report:

But in this case I can't open the file with mswindows bsplayer:

Warning: Unknown file format (FMP4)

Movie info:

The same happens when I use vcodec=xvid instead of vcodec=mpeg4
