Getting NTP timestamp of RTP data

[Ingo Lütkebohle]

Hi,

for synchronization of RTP streams from multiple sources, I would like to
acquire the NTP timestamp of data. However, I have not found an attribute
on the gstreamer buffers that would tell me this timestamp.

I have successfully retrieved the timestamp by snooping on the rtpsession's
sync_src pad and decoding the sender report, so its there, but I've been
wondering whether there is an easier method.

Just for clarity, this refers to cases where I am using gstreamer to
receive RTP data as a client, and negotiated using RTSP.

Anything?

cheers,
