As a side note, (I'm also interested in the answer as an aid to grasp 
the ffmpeg code), may I ask why you care ?

Of course there are bursts, but the average bitrate is respected. And on 
a realistic IP network (especially mobile), this may even be the result 
of an intervening network component (a buffering gateway). So even if 
you twist ffmpeg's arm hard enough to do the very smooth sprinkling you 
are after, it may still be completely wasted by external constraints.

Can you elaborate on the specific receiver you are using, which is not 
able to buffer these bursts ?
