Do a search on googGroups, was mentioned a lot of times, you can use rtp_frward option to forward publishers stream to ip:port where gstreamer will pick up as udp src

No, as Mirko said, RTP forwarders are the need to go. They're explained at length here: https://fosdem.org/2020/schedule/event/janus/

You guys should definitely check the FAQ before asking questions, there are A TON of videos and slides for different requirements listed there.

Hm... why not? For example I was able connect from GStreamer to both Chrome and Firefox (with help of webrtcbin element)? Any reason why do you think it will not work for Janus Videoroom? I'm sorry, maybe I'm miss something obvious...

I'm not saying it won't work, just that it would be easier, and using less resources, with RTP forwarders, especially if all you want to do is send the video of a publisher to gstreamer for processing there. With webrtcbin you need a WebRTC PeerConnection, which means connecting to Janus, do all the signalling needed for a real participant, subscribe to the stream, DTLS/ICE/etc.: it's a lot of work, when all you really need to do is tell the plugin to relay the RTP packets to a specific address out of context.

If you want gstreamer to send media to a VideoRoom, instead, then webrtcbin is definitely a good choice (which I've used myself for a couple of things).

I'm totally agree, you are right, use rtp forwarders will be much simpler than complete peer connection. So it's up to specific case what to choose. I just was worried I've missed some problem related to webrtcbin connection to Janus.
