Chrome 76+ DataTrack incompatibility with 2.X Mobile SDKs in P2P Rooms

[ceaglest]

Chrome 76 added support for a new SDP format for data channel negotiation. This new SDP format is not compatible with 2.x Android and iOS Video SDKs when used with P2P Rooms.

What is the impact?

In a P2P room, Chrome 76+ Participants and affected mobile SDKs might not be able to subscribe to each other’s data tracks. The issue occurs when the Chrome Participant connects to a Room after an incompatible mobile Participant has already connected.

Are audio and video tracks affected?

No. Participants can subscribe to audio and video tracks and they continue to function as expected.
