"fatal: no colibri channel" with meet.jit.si

[jmatsushita]

Hi there,

Just tried to test gst-meet running the master branch at commit 5b1f842 built with cargo build --release on macos with the public meet.jit.si server. It gets "pretty far" into connecting but fails with a fatal: no colibri channel. Here's the end of the log:

2024-07-13T21:50:27.662463Z ERROR fatal: no colibri channel

[jbg]

Jitsi has recently switched from defaulting to WebSocket for the secondary ("Colibri") signaling channel that goes directly from the client to the JVB, to defaulting to SCTP. Most likely meet.jit.si is offering only SCTP here. We don't yet support that, so it bails out. I'll use this issue to track progress to supporting SCTP for Colibri signalling.

[daimoc]

Hi @jbg, what is your plan for Colibri SCTP support ?
Do you have identified a rust SCTP stack ?

[c-zolotko]

I also got this error in gst-meet trying to connect to our self-hosted docker running stable-9753, still works in stable-8252.

[SkyTaurus]

Hi @jbg Any progress?

[anujdeshpande]

@c-zolotko what kind of a pipeline did you use to connect to stable-8252? I am trying that out on my selfhosted instance but failing - xmpp socket connects fine, but I get a bad response

@anujdeshpande

It's been awhile since I worked on this and I'm sorry for just now getting back to you but I believe we got audio and video working, just the A/V was out of sync. I gave up because I was spending too much time on it. We were using NDI libraries in gstreamer which added a complex layer itself but was a fun project. According to my notes this was my last pipeline that was semi-working.
