H.264 support in MPEG-4 format files is supported, but apparently not 
completely.  (Support for the H.264 video codec was provided by 
someone else.)  If you're inclined to look into this, then the code 
to look at is "QuickTimeFileSink.cpp".

As always, when you're using the "-4" or "-q" option with a video 
stream, be sure to specify the correct frame width, height and frame 
rate, using the "-w", "-h" and "-f" options respectively.
