When you don't receive a frame, it's probably because one or more of 
the RTP packets got lost.  If any of the (very many) RTP packets that 
make up a JPEG frame get lost, then the whole frame is discarded.

JPEG is a very poor codec for video streaming.  You should use a more 
efficient codec (specifically for video) instead.
