Ugh... Very old thread, indeed. I completely forgot it :)

But I now have (somewhere in one of my local trees) a patch that
should add support for compressed v4l2 (only JPEG, for now)....
I tested it with a "logitech something" webcam (providing MJPEG
compressed video), and I have some reports that it works with other
v4l2 compressed sources (but I have no details about them).

I'll search for such patch and post it (it might be just a forward port
of the patch you are posting), after re-testing (just to make sure that
some recent change did not break it).
