Audio and video are sent in separate RTP sessions each with their own random timestamp offset. They are synchronised at the receiver using RTCP Sender Reports (SR) sent by the sender. RTCP SRs map the RTP timestamps of an RTP session (e.g. video or audio) to an NTP timestamp allowing the receiver to synchronise audio and video.

I know live555 library uses RTCP SR reports to synchronize audio and video streams, but doesn't use the rtp-info header present in the PLAY response. It does, however, make this header information available for clients to use - see "MediaSession.hh". You're correct, though, that the RTP-Info header information is the

The video renderer only uses the current one and queues the following only if the upstream filter delivers multiple samples (older video renderers that use overlays will only support 1 sample at a time). The DirectSound audio renderer has an internal 1 sec buffer. Do I HAVE to implement IReferenceClock? Not for the renderers to sync the streams.

AV synchronization can be an issue in television, videoconferencing, or film. In industry terminology, the lip-sync error is expressed as an amount of time the audio departs from perfect synchronization with the …
