hmmm. Im seeing a few places where safari doesnt have tranceiver on an rtc track event and maybe adapter.js is something to try

no it turns out we are already using adapter.js 😐

Hmmm, I've been digging a lot into this and it turns out the tranceiver is there as per the spec, but the "mid" property isnt

mickel8 do you have any idea why this is happening on safari? Have you seen this before? Im now looking at using the latest Adapter.js in the hope it might help, but we have a fairly recent version and its still happening...

But we don't officially support safari. At least not at the moment so not everything might work

Hi again 🙂 Im still stuck on this. I figured out the null tranceiver thing and it was a red herring I think. The actual error seems to be that safari just cant establish a peerconnection with the membrane server. I have traced out the guts of the sdp offers and answers and it seems to just loop over getting turn servers, creating and sending a local offer, getting an answer and ice candidate and then it gets the turn servers again and loops

from what I can see, Safari is not generating a local ICE candidate at all - chrome does it immediately after the local offer generation but safari is offering nothing

What version of RTC Engine and membrane-webrtc-js are you using?

Could you try to move to engine 0.9.1 and membrane-webrtc-js 0.4.0 and see whether the bug still occurs?

It seems to just cycle between sending an offer -getting an answer and a remote ICE candidate but never triggering the local ice candidate handler

(This is tracing I just jammed in to the built membrane rtc js lib to help me see whats happening as the socket is too noisy)

So webkit doesnt give offers until you get access to the user media via getUserMedia. Does it matter I wonder that we are only asking for access to audio not video. Does the membrane rtc lib require some video stream. Im going to test that theory

no local ice candidates when getting permissions for both video + audio

you can the RTCPeerConnection is just stuck in the gathering state:

If you have any ideas (I know safari is not supported) I could do the digging to try to get it to work

ok, i think we have some progress - the new versions actually do work if the test device is not emulated and the user is not in a web view

I am sorry but we are really focused on stability/quality issues at the moment

so it's hard to find time for anything else 😦

Membrane js 0.2.3 + safari 16 -> tranceiver is null on event

pshort.
