[MPlayer-users] problem extracting audio from divx

[Jaap Struyk]

Hello,

Trying to create a (mini) dvd from a divx I ran into the following
problem:
creating a m2v stream from the source with -of rawvideo and
vcodec=mpeg2video works splended, but when I try to extract the ac3
stream with -ovc frameno -oac copy I end up with mplex telling me:
**ERROR: [mplex] File frameno.avi unrecogniseable!
mplayer -identify frameno.avi3 gives me:
ID_VIDEO_FORMAT=FrNo and info about the video stream, so it seems that
it isn't a audio only stream.
So I renamed it to frameno.avi and extracted audio with:
mplayer frameno.avi -dumpaudio -dumpfile kdvd.ac3 with mplex giving me:
**ERROR: [mplex] File kdvd.ac3 unrecogniseable!
Hummmm, mplayer -identify kdvd.ac3 gives me:
ID_VIDEO_FORMAT=DVSD and somewhere along the output Audio: no sound

How do I end up with a true audio-only stream?

p.s. If I try to convert the avi with -ovc frameno -oac lavc \
-lavcopts acodec=mp2:abitrate=112 I get the same results.
