[MPlayer-users] "Too many audio packets in the buffer:" error message

Wed Oct 20 11:38:59 CEST 2004

I tried to encode a vob file from my hard drive but was getting the 
above "Too many audio packets in the buffer:". I tried going from the 
dvd and closing all other apps. -- same problem.
I understand that this problem arises when the video encoding is way 
slower than audio encoding. Isn't there some way we can slow the audio 
stream to match the audio stream?

Here's my command:
mencoder dvd:// -aid 130 -noskip -skiplimit 0 -vf crop=720:352:0:64 -oac 
copy -ovc lavc -lavcopts 
vcodec=mpeg4:keyint=120:vpass=1:autoaspect:vbitrate=638:psnr:vmax_b_frames=1:mbd=2:v4mv:trell:cbp:mv0 
-o Crouching\ Tiger\ Hidden\ Dragon.avi

I got the following output (anyone see anything noteworthy?):

Too many audio packets in the buffer: (4096 in 8257536 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.
