视频流系统

I'm trying to find a solution to be able to stream a video to users connected to my website. I explain :

  1. Video source I film a conference I'm doing, where I have multiple video sources, and mix it live using a software like vMix. This software can live upload the video to a server (via an URL).
  2. Server ??
  3. Website When the video has begun, users can go on the website (codeigniter framework) to see the video.

The problem I'm facing is for server part. Actually, I know PHP would not be able to handle this kind of job. I have made some researchs and assessed that Node.js or something like that could do it (maybe using WEBRTC). The problem is that I just want a server that redistributes a feed, not something like a video chat with multiple feeds to manage...

I would like to know if there are alternatives, to build this kind of little (a hundred users) stream server.

Video streaming is quite specialised technology and it would definitely be easier to use an existing streaming server than to build one yourself.

The servers will (depending on your needs and the user experience levels you want) handle things like fast start, ABR (allowing the browser clients in your case to switch between different bit rate videos depending on network conditions etc), packaging the video in the right streaming format etc.

You can find open source streaming servers such as:

Or commercial ones such as:

Good tutorials exist for both.
