Ross, I am not sure if this has been already done but can I suggest that you scale the timer resolution of the testOnDemandRTSP application to 1 ms . This would help to lower the jitter of the RTP packets sent. Under Windows you can use TimeBeginPeriod(1) to do this. With Linux I guess there mu

(Note that this particular problem has nothing to do with 'trick play'; your streaming problem happens even if no index file is created. It probably also doesn't have anything specifically to do with H.264 (see below).) Problems like this (VLC being able to play a file OK, but 'stuttering' i
