demo's don't work "WebRTC not available"

[nwheatle]

When I click on any of the demos, I get a page that say "WebRTC not available".

I'm getting the same issue when trying to open any example through a desktop chrome 78.0.39 on Mac OS(Mojave).

Opening them on my android(Mi POCO F1, Android Pie PKQ1, Chrome 78.0.39) prompts the camera permission but then it's followed by the following screen and nothing else.

Years later, still the same issue :(
