[MEncoder-users] [Too many video packets in the buffer - Too many audio packets in the buffer]

Sat Apr 5 23:07:51 CEST 2008

Hello everybody,

First of all, sorry for my bad english...
I'm actually trying to encode a vob file to an avi one.
To do this, I use the following command:*
 mencoder -sws 2 -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=23109:autoaspect:vhq:vpass=1 -ffourcc XVID -o
/dev/null GDB.vob
*
But mencoder outputs messages like:
*Too many video packets in the buffer
Too many audio packets in the buffer*

When I searched how to solve this, I seen things about telecine and
progressive movies.
I am not absolutely sure, but I think it's not the problem:
I have never seen "*demux_mpg: 24000/1001 fps progressive NTSC content
detected, switching framerate*" while playing the DVD or the vob file.
And for telecine, I haven't all understood, but when the movie is started
and that I type on the point key, I never see things like "PPPII".

This is a part of the trace:*

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.
