Hello, as clearly mentioned in the README we don't support using H265 with WebRTC, mainly because the great majority of browsers do not support it.

The OBS team decided to unlock the WebRTC-H265 combination last month (see obsproject/obs-studio#10577) , therefore we can add support for ingesting H265 streams with WebRTC, but not for reading them from the server.

webrtc: support publishing H265 tracks (#3435)

IMPORTANT NOTE: this doesn't allow to read H265 tracks with WebRTC,
just to publish them. The inability to read H265 tracks with WebRTC is
not in any way related to the server but depends on browsers and on the
fact that they are not legally entitled to embed a H265 decoder inside
them.
