The video chat demo app based on WebRTC
AppRTC parameters (https://apprtc.appspot.com/params.html)
A number of settings for the AppRTC video chat application can be changed by adding URL parameters.
For example: https://appr.tc/?hd=true&stereo=true&debug=loopback
The file using the parameters is apprtc.py. More Google-specific parameters are available from the MediaConstraints interface.
For more information see AppRTC : Google's WebRTC test app and its parameters.
