Hi! As RTCP SR packets carry NTP ans RTP timestamps I would like to know how they are used to sync to streams. I found out that the RTP timestamp in the RTCP SR corresponds to the timevalue which the NTP timestamp indicates.
But why can't I find the RTP timestamp in the packets of my videostream? For example I have (taken from wireshark): RTCP Sender Report: Arrival Time: Jul 2, 2007 14:34:00.669515000 MSW and LSW as NTP timestamp: Jul 2, 2007 12:27:10.3529 UTC RTP timestamp: 2965177770 But my video stream has timestamps beginning at higher values. RTP packet: Arrival Time: Jul 2, 2007 14:34:00.651933000 Timestamp: 3583401060 How do these times correspond to each other? What leads me to this problem is the question, how I can keep a video stream synchronised to an audio stream when I manipulate the video stream on its way to the final recipient (i.e. transcoding it)? When I send out the manipulated videoframes, they get a new RTP timestamp offset and the receiver will not be able to sync them to the unmanipulated audio stream...? _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
