Re: [Linphone-developers] oRTP: receiving packets with unknown TS delta?

What value for TS should I pass to rtp_session_recvm_with_ts()? Would passing 0 work? or do I have to work it out based on the payload type of the first packet? My problem is that I don't know the rate that I should be reading packets in. I just know that I want a packet whenever one is received.

oRTP does not need to know about the delta between packet timestamp. The only
prequesite is to have a PayloadType that defines a clock_rate.
Then you can use rtp_session_recvm_with_ts() and dump out packets.

Is is possible to use oRTP to receive an RTP stream, when the delta
between packet's time-stamps is unknown? I want to write a Payload
Type agnostic recording tool, which just records packets to disk/ stdout.

I guess I am just looking for a rtp_session_recvm() type function,
which just returns the first available RTP packet. Would be nice to
be able to use the oRTP networking code, rather than write my own
routines to do it.
