Question

I want to create a webrtc broadcasting demo

https://webrtc-experiment.appspot.com/socket.io/

Total upload bandwith = number of user * ( 30 kb approximate to upload 1 video)

so i want to develop like this

Answer 1

While your thought of using WebRTC in a small group multipoint manner, this comes with a lot of complexity and reliability issues. Most WebRTC apps that relay through peers tend to be not so reliable in my experience. In concept it's a great idea, but I haven't seen any solid practical applications. The most reliable implementations of scalable WebRTC broadcasts tends to use a server in the middle. You can use something like Janus, but I prefer Kurento which is open source. There is also a platform called OpenVidu that sits on top of Kurento if you don't want to have to get into the nuts and bolts of how things works, but is less customize-able. You can even record, transcode and process the video in real time.
