This is probably because your "ServerMediaSubsession" subclass's 
"createNewStreamSource()" function is not setting the result 
parameter "estBitrate" correctly.  That parameter needs to be set to 
the (sub)stream's estimated bitrate in *kilobits-per-second*.

Your frame's presentation times need to be aligned with wall-clock time.
