WebRTC SFU: How to learn whom does the video track belongs to?


#1

I want to know where’s every video track comes from in a webrtc sfu conference. I try to distinguish them by the ssrc but seems not work. For example, if A sends a video stream tag with ssrc1 to B, B will receive a new ssrc video track but not ssrc1. I think server has changed the ssrc before the dispatch.


#2

This is correct. Each side is completely independent on SSRC and other details, however newer versions provide messages that contain information about the streams[1].
