How to setup a livestream Node js server that accepts RTMP and/or RTSP streams and use WebRTC to stream to clients (browsers)?

Question

I am trying to set up a live streaming server using Node js and stream it to clients. The server needs to cater both RTMP and RTSP incoming streams.

So far, what I have done is to use node-media-server to accept RTMP streams and remux to HLS/DASH. This is working fine but produces a huge latency of around 10-20 secs which is not acceptable in my application. I need to have low latency (as much as possible, maximum of 1-2 secs delay). I am also trying to avoid using Flash plugins in the client-side since it will be deprecated by end of 2020.

Further research, maybe I can use WebRTC but is there a way to set up a server that still accepts RTMP and even RTSP (maybe convert to RTMP afterward) and then stream via WebRTC? If so, how? Or are there any other suggestions?

Answer 1

That is possible (and people are doing it today!)

For fun I did rtmp-to-webrtc which is a Go server that accepts RTMP and serves via WebRTC.

You could easily add a RTSP server and do the same. I haven't done it myself, but there are a few Go RTSP servers out there.
