Turns on my camera, but doesn't seem to work. If you can set up a local node server instance, I'd go with this instead:
I used easyrtc in a project a few years back, but now, they themselves are recommending open-easyrtc as the better open source option. It's a fork of the original easyrtc by one of (maybe *the*) main contributors. I installed it and ran the multi-party demo. I connected with my desktop webcam and a mobile device and it worked great. You don't need to write any code, but you'll need to be able to install and run a node app locally. (To connect with a second device, you'll need to use server_ssl.js.)
