Problem connecting Android Chrome browsers

[ryk...@gmail.com]

All of a sudden (probably linked with Android Chrome 96)

We can't connect any Android devices.

User A Chrome 96, Mac

User B Chrome 96, Android

User B sends offer to User A.

When User A sets setRemoteDescription from the offer we get the following error:

DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote offer sdp: Failed to set remote video description send parameters for m-section with mid='1'.

Any thoughts on what might have happened? Our code hasn't changed at all!

I've seen some similar posts relating to codec issues. But these were mainly focused on Java. So any thoughts on browser based WebRTC would be great,

Thanks

Thanks for the link to the issue.

Yep, it's 100% this. I'd actually commented out the only part of our code that deals with codecs and this fixed the issue.

So guess i'm waiting on this bug to close before i can bring that functionality back into our code.

Love this group

Thanks
