Usually MPEG formats are transmitted as streams but encoders
and decoders often work on full frames. Forcing the frames
into a byte-oriented stream seems like a loss of information.
Isn't V4L2 inherently frame-oriented or is there a way to
pass streams/packets, too? A stream contains frame indicators
of course, so the driver could be looking for them but that
means more work for the driver.

I am not aware of anything useful in this area.

It is possible. In any case I anticipate the number of
MPEG4 devices is going to increase pretty soon.
