[MEncoder-users] audio severely out of sync when encoding a video from a DVD-RAM

[Tomas Vondra]

Hi,

I do have a hard time enconding video recorded on a DVD-RAM - no matter 
what options I use the resulting audio is severely (a few seconds) out 
of sync :-(

When playing the original video (in mplayer) works perfecly fine, but 
once I run it through mencoder, it's broken for some reason.

For example this:

$ mencoder /mnt/cdrom/DVD_RTAV/VR_MOVIE.VRO -oac lavc -ovc lavc 
-lavcopts acodec=libmp3lame:abitrate=64:vcodec=mpeg4:vbitrate=2000 -vf 
pp=lp,scale=600:450 -sws 2 -o ~/out-of-sync.avi

results in video with audio out of sync. What's wrong with it? I've 
tried to search the man page & mailing list, but no luck.

thanks
Tomas

PS: I've tried to encode it using ffmpeg too and it works (the audio 
sync is perfectly fine), but I'd like to use mencoder (the DVD is 
scratched and mencoder handles the corruption much better).
