Getting NTP timestamp of RTP data

[Ingo Lütkebohle]

Hi,

well, reading RFCs more thoroughly is always a good idea, but this is
really a question on a gstreamer feature, so I don't quite make the
connection of how that answers my question. Maybe I wasn't clear there, so:
Does gstreamer makes the NTP timestamp from the sender reports available
somehow as a property, or caps, or not?

btw, one more addition: My "multiple sources" are different cameras
accessed via RTSP. Last I checked, gstreamer couldn't synchronize across
RTSP sessions, and, anyway, I'm also interested in the absolute time-stamps
for other reasons (our recording period stretches across weeks).
