I conjecture that at least part of the visual improvement that results from
dropping entire frames (when RTP packets are lost) is the fact that by 
entire frames, ffplay has a better chance of catching up with the RTP 
There may be other factors at work as well.

I presume that you have your favorite way of generating an RTP stream.  If
so, then I suggest that you just send it your favorite video and watch what
happens with and without my patch.   (My favorite video is glxgears.)

And regarding my patch: Given that I am new to this list, I did not want to
be presumptuous and send my patches up.  Shall I do that now?
