What is happening in this pipeline (rtpbin sending and receiving simultaneously)

This is using the rtpbin element, which in addition to doing RTCP also
has an rtpjitterbuffer on the receiver side, which is probably the
reason why it works better for you. Doing RTP without rtpjitterbuffer
requires very good network conditions.

RTCP won't reduce latency or solve anything on its own, but it can be
used for various control and statistics. It's not used for anything
meaningful in your pipeline though.


Also in your pipeline, you set buffer-mode=4 ntp-sync=true and
sync=false on the video sink. This does not really make much sense.
What's your goal, what's the bigger picture?
