--- Comment #7 from Chad Phillips <webkit at xylil.com> ---

I'm pretty sure the documentation you pointed me to is incorrect. Here is the relevant section for clarity:

"Currently, all devices running iOS are limited to playback of a single audio or video stream at any time. Playing more than one video—side by side, partly overlapping, or completely overlaid—is not currently supported on iOS devices. Playing multiple simultaneous audio streams is also not supported."

This is *definitely* false for the case of multiple video streams in the WebRTC case -- I've already run scenarios with up to seven video feeds being received, each in their own video element.

It does seem to be true that I can only have one active publisher stream (see bug https://bugs.webkit.org/show_bug.cgi?id=179363 for more details on this unfortunate current limitation)

I have yet to test the case of multiple audio elements on iOS, but will report back here if I learn anything.

It does seem that the iOS media restrictions are a poor fit for WebRTC -- some of them really hamstring the capability of the standard.
