--- Comment #3 from Chad Phillips <webkit at xylil.com> ---
Still trying to find a simple way to reproduce this issue for testing.

In the process I believe I at least found why the echo stops if I display the first video stream again.

As a simple demonstration, I recorded the issue, viewable here: https://youtu.be/eVQVSy6Edt8

The first playing video is a peer connection that's also sending local audio/video to a conferencing application. When I start a second peer connection that also has local audio/video, you'll see that the first video stops (audio stops too).

This doesn't seem to accord with the rules listed at https://webkit.org/blog/7763/a-closer-look-into-webrtc/, which say "MediaStream-backed media will autoplay if the web page is already playing audio", so I'm wondering if another bug is in order here?
