Hello everybody,
I'm trying to convert a series of RV40 .mkv cartoons to XVID's but the
resulting .avi file always has a very huge lag between audio and video.
"Very huge" means approx. 4 sec of lag after 40 sec of video
I'm using :
~> mencoder -oac mp3lame -ovc xvid -xvidencopts cartoon:bitrate=700 01.mkv
-o 01.avi
which outputs :

(i didn't let the conversion occur till the end because it's very slow on my
system and i can see the lag long before the end of the conversion)
I also tried to convert to msmpeg4 with lavc :
~> mencoder -oac mp3lame -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=800 -o
01.avi 01.mkv
which gives the following output :

Too many audio packets in the buffer: (4100 in 748904 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
Flushing video frames.

(I let this one run till the end to get the final output because converting
to msmpeg4 with lavc is much faster than converting to xvid and as you can
see something went wrong at about the half of the file)
Could anybody explain to me what i'm doing wrong ?
Thanks !
