 Taht's fine, it works and will work since there is ONLY 1 audio stream.
 What if there are 2 audio streams and you want to copy both, how will you
 do it? you can't use map 0:a since you need to add map 0:v and that will
 fail.

 so ALL I'm suggesting is DON'T mark teh mjpeg as video stream, why not use
 the flag information provided in libavformat and mark it as an attachment
 (which is what it really is) and EVERYTHING will start working?
