Old version of mjpegtools that had a bug in the lav2mpeg script
(mplex had changed but updating the script was overlooked).

That tells me that the audio format in the input file wasn't
recognized. What type of audio is supposed to be present in the
source file?

Right - don't use "-m" with mplex
The -m option hasn't been around in eons (mplex can figure out if a
stream is MPEG-1 or MPEG-2 without an option).
What version of mjpegtools are you using? If it's not 1.6.2 (the
last release) you might try upgrading to that. If things still don't
work then the CVS version might be worth a try - I know that the
lav2mpeg script in the cvs version does not use '-m' with mplex.
You might also try using 'mplayer' to dump the audio and/or video
streams (-dumpaudio and -dumpvideo). Then you can experiment with the
component streams without going thru lav2mpeg.
