OK.  It looks like the codec is actually doing something.  It gives
skipped frames probably because the input isn't different enough?
When I set Iframe interval to 1 it gives a sequence of Iframes.

So.. Let's look at what actually comes out. Concatenating 3 frames to
the file /tmp/mpeg gives:

tom@zzz:/opt/nfsroot/neuros/tmp$ file mpeg 
mpeg: MPEG sequence, v4, video

tom@zzz:/opt/nfsroot/neuros/tmp$ mplayer mpeg 
Playing mpeg.

Dumping a bit more it seems to be able to play it.  Alright.  The rest
seems to be tweaking.  However it is much slower than I expected.
