Really nice Project, I'm working with WebRTC my self and i struggled with different things that cause the problems mentioned in the comments.
For example Safari has some weird WebRTC quirks (getUserMedia/codec differences vs. Chrome) further more the stutters are often scaling problems and not because of the rendering.
And i have seen in my analytics for my App https://sharry.live that there are often connection problems because of restrictive network settings which can be handled by a TURN Server.
Wow this is a great idea and I wish my local climbing gym had something like that. Maybe it is a good idea to put a help section for every route and visualize this.
