Hello, first I would like to thank you for the beautiful work you have done, it is simply incredible. I would like to know in webrtc is it possible to add support to H265 in WS

[aler9]

@brunobaraobr streaming H265 to the browser will be possible through Low-Latency HLS, please follow #469

Unfortunately WebRTC doesn't support H265 except when it's used inside macOS Safari, therefore at the moment it wouldn't be much useful to implement it.
