Signalling for video stream from raspberry pi

[nickdex]

We have decided to use web RTC to directly connect browser and raspberry pi to stream video data.
Web RTC requires signalling pathway to exchange SDP and ICE candidate information.

Draft Flow Design

• Client will make a http post request with offer SDP and ICE information to Node server.
• It will be forwarded to RPi via websockets.
• RPi will generate answer SDP and ICE information.
• It will be sent back to Node server and will be returned to browser

Matrix is good candidate for WebRTC signalling medium.
