No, RTMP is not implementing RTP. rtpjitterbuffer works with RTP
packet, by reading the RTP payloaded timing information. Also,
rtpjitterbuffer is for live source, rtmpsrc is not a live source in
GStreamer term.

What you describe here is a mix of network and transmitter jitter. You
need a queue that is as big as the worst "normal" jitter. For playback,
we usually pick something close to 2 or 3 seconds. If you need lower
latency, don't use TCP type of streaming. If that is not possible, you
might want to tweak your transmitter/server to never burst, and enable
google tcp traffic control.
