There are open-source tools that let you break down the frames of a motion-JPEG AVI file into individual files, as well as split out the sound track. I would imagine that these tools can do what you want—unfortunately, they don't necessarily do it in a way that's very convenient.

Somebody could get out the XS tools and put together an Perl interface to the relevant libraries, of course, but it doesn't look like anybody has (though somebody on that project has the expertise, since there's a YUV4MPEG Perl module). If you're so inclined, though, do please post your progress back here: I'm sure you're not the only one who has wanted to do this. (Very sure, in fact.) But failing that, you may well be able to cobble something together using the MJPEG tools linked above.
