Video chat web app using WebRTC safari, IE possible?

Apple claims that Safari 11 will support WebRTC on their desktop and mobile devices. We have no information at this time on if or when we may add support for WebRTC with Safari.

Yes, Safari 11 supports WebRTC. Although, Safari only supports the H.264 video codec and NOT VP8.

In order to stream to Safari you must change the preferred codec to h264 in your Application.xml file as seen below.
