[Live-devel] RTSP client and jumping timestamps

Hi, Ross!

Thank you, the function RTPSource::hasBeenSynchronizedUsingRTCP() is
exactly what I need. Now my RTSP wrapper gives video and audio to
synchronizer only after all of MediaSubsessions are synchronized, and it
works fine!

Regards,
Denis.

See

(Also, you should not be concerning yourself with RTP timestamps; 
instead, just look at presentation times.)

However, VLC handles this automatically, so I don't know why you 
would be having problems with that...
