HTML5 does not support RTSP. Therefore, to use RTSP in HTML5, you must use WebRTC. The usual structure is IP Camera (RTSP) -> Server -> Chrome (HTML5) structure. 1. IP Camera (RTSP) <-> Chrome (HTML5) method, how can I connect IP Camera to HTML5 without server? 2. Is WebRTC transcoding RTSP to VP8 supported by Chrome? Thank you for your advice. Have a good day

That's the usual structure, which is entirely wrong for WebRTC. You want to ditch your RTSP library and implement WebRTC. So the new structure would look like

IP Camera (WebRTC) -> Remote Peer (Chrome, Firefox, etc.)

Or if blocked by NAT, you'd need a TURN server:

IP Camera (WebRTC) -> TURN server -> Remote Peer (Chrome, Firefox, etc.)

2. Is WebRTC transcoding RTSP to VP8 supported by Chrome?

RTSP is a networking protocol. VP8 is a video encoding method. They're totally different things; you can't transcode from one to the other.

You can use Gstreamer webrtc plugin.

IP Camera(RTSP) -> Gstreamer(WebRTC) -> Chrome(HTML5)

And you also can use Gstreamer to transcoding , it's really simple.

Just FYI, Janus does support RTSP-to-WebRTC translation. No transcoding, though, which shouldn't be an issue if your camera supports H.264 baseline:
