[MEncoder-users] audio sync failure

[Uzu Maki]

hi everyone,
I am new at using mencoder... I am using the Debian unstable version.

here is how I use it:
"
mplayer -vo null -ao pcm:file=audio.wav dvd://1

oggenc -b 128 audio.wav

nice -n 3 mencoder -nosound -ovc xvid -xvidencopts bitrate=1500:pass=1 -vf
crop=720:368:0:60,scale=680:328,pp=lb dvd://1 -o /dev/null

nice -n 3 mencoder -nosound -ovc xvid -xvidencopts bitrate=1500:pass=2 -vf
crop=720:368:0:60,scale=680:328,pp=lb dvd://1 -o "movie.avi"

ogmmerge -o movie.ogm movie.avi audio.ogg
"
this work like a charm for small vob files like cookery/music shows recorder
from TV on DVD.
but when I try to encode larger files (>2Go) I get a delay (not constant) in
the audio stream.
Impossible to get the sync working... even though the audio and the video
are separately perfect...

I've seen that I am not alone...

but I can't get over that trouble...
If someone could point me in the right direction...

thank you very much in advance !

PS: I tried with mp3 too... average or constant bitrate... avi, ogm... no
change...
