So like i mentioned before in bug

proof-of-concept implementation of RECORD | PLAY mode for the same mount point

I'm pretty sure it's far from ideal, but at least it's working on my test
pipeline. I will be glad to hear some comments to know if I'm going in the
right direction and didn't do some obvious mistakes.
Thanks.

Sergey, thanks for your patch. If I'm reading your code right you're creating
separate rtpbins for play and record - is there a reason for that?

--- Comment #3 from Sergey <***@gmail.com> ---
Yes, I've did separate rtpbins for play and record sides. Just thought since on
record side and play side we will have different users, it will be better use
different rtpbins. Do you think the same could be done with the single rtpbin?

FYI, a little bit improved version of above patch (and some other related) is
available on GitHub: https://github.com/RSATom/gst-rtsp-server/commits/master -
just don't sure it well enough to post it here...

I think it should be in the same rtpbin, possibly even in the same rtpsession.
The RTCP is supposed to be shared AFAIU, or not?

Sorry, can't answer this question. I'm not familiar so well with rtp internals
:(

My understanding is that you want to use the same RTPbin only for streams that
are meant to be synchronized together, otherwise we shouldn't.

--- Comment #8 from Sebastian Dröge (slomo) <***@coaxion.net> ---
While generally I agree, the problem I see here is that AFAIU there should be a
single RTCP stream for this case. With multiple rtpbins you would have
multiple.

--- Comment #9 from Sergey <***@gmail.com> ---
Maybe it's dumb question, but why it should have single RTCP? Since pipeline
inside rtsp server could do some additional job (for example I want show some
splash screen when there are no input on record side), there just will be no
receiver for rtcp. Other case, if pipeline do some heavy operation (transcoding
for example) - there are no any meaning send rtcp to record source. Or maybe I
don't understand well purposes of rtcp channel...

Nothing to do with "proxy" really, so renaming the bug :)

Without, you create loops in the pipeline graph.
