RTP timestamps are only synched within a single RTP session and source. If you 
want to have audio _and_ video (or multiple sources), you need to correlate 
timestampts from different sessions. That's done with RTCP-SR.

The only exception is if you're doing MPEG Transport Stream over RTP to mux 
audio and video on the same RTP session. Or then you'd have to assume that 
all sessions have the same RTP timestamp frequency and are synchronous, but 
that's completely not specified.
