[MEncoder-users] Sync problem with newer mencoder version

[Florian Sollinger]

Hello!

I know audio/video synchronisation problems have been discussed before,
but i can't find a solution to my problem:

I have a mpeg 4 video, recorded with a Nokia mobile phone. The video has
a variable framerate.
Now i want to re-encode it into a flv file.

With the mencoder of MPlayer 1.0rc2-4.2.1 everything works fine. But
with MPlayer GIT-6e54f40-4.2.1-sjlj-Kovensky-mt 20090304 or MPlayer
SVN-r29040-4.3.2 the audio is out of sync. What happened between this
versions?

The convert string i used was:
mencoder input.mp4 -ofps 24000/1001 -mc 0 -of lavf -oac mp3lame
-lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts
vcodec=flv:vbitrate=400:trell:v4mv:cbp:last_pred=3 -vf
harddup,scale=480:360 -o output.flv

Unfortunately i need to run this on a server where i cannot install
another version.

Thanks for your help.
Florian
