define sane :-) 
I have tried several different approaches. the one that seemed to work
the best was to simply sum the payload size for each frame. According
to one of the ffmpeg guys, this should be an ok way to do it - as long
as the timestamp is increasing for each frame (but is the samme for all
packets containing fragments of the same frame).
