The intent is to stream a camera feed watching the monocle display.
In this case a phone looking at the monocle using a mount like below.
The issue here is I'm not able to select the macro camera which would be better suited using web enumerateDevices()
Anyway I have working example on the vonage branch which is a paid service.
They do all the heavy lifting of video for you but you pay for it.
I have not put the time in to setup WebRTC myself from scratch.
