How can I have a server stream a video with WebRTC?

Question

My current use case is that I'm trying to mock a system that uses WebRTC for live video streaming (for a robot). This way, I don't have to be connected to the robot to develop the client.

My issue as of now is that I have no idea how to stream a video using WebRTC to connected peers. I've seen many examples of how to do this from client to client using a signaling server, but other than directly sending the video buffer using socket.io, I haven't seen an example of server -> client WebRTC streaming.

I'm planning to use Node.JS for mocking the video stream as I've been using it for the rest of the robot's systems.

It really isn't that different though client to client or server to client. You want to stream/broadcast a video to all the connected peers. Think of your server will be a client in the setup.

You can also use a WebRTC solution like Janus Repo it is a simple gateway and completely open source. Refer to - WebRTC & Dev API's for more info.

If you find latency issues after peers have increased in number you can check - Mesh , Routing , Multi peer architecture for some solutions for it.

Hope it helps.
