Hello!
I use live555 2014.01.29.
For run on-demand RTSP-server I write OnDemandServerMediaSubsession
subclass with implements createNewStreamSource, return
H264VideoStreamDiscreteFramer, and createNewRTPSink, return
H264VideoRTPSink.
Unfortunally programm exit with "Segmentation fault" after PLAY command.
OpenRTSP log:
