• Using ffmpeg to build a streaming server to stream static media files (broadcast behaviour)

  15 février 2018, par MiDaa

  I’ve read some online articles and SO questions, most of them are about streaming MY video to SERVER like youtube or switch.

  This is about a project of interest, here are what it should do.

  • Work on a Linux server
  • Serve media(preferably multiple format like mp4 mkv) files to client through rtp protocol maybe ?
  • Server could set a specific time to start the streaming or end it
  • Server could pause and resume the streaming(?)
  • Multiple clients connect and play the stream at same time(sounds like a basic feature)

  After some research, I found that ffmpeg is a great open-source candidate for such a project but as a newbie in this area, I’m having a tough time understanding how this whole thing work.

  As this(ffmpeg doc) states, it looks like just a one liner command. But I don’t find anything fit my feature listed above.

  Can ffmpeg be used to achieve those ? If not appriciate any suggesstion on where I should be looking at.

  EDIT :

  • Target devices : iPad,iPhone, Android phones should be able to watch the stream using a web browser(assume a modern browser)

• TypeError : Cannot read property 'url' of undefined - ws

  28 juillet 2021, par Bawantha Rathnayaka

  I am trying to get URL starts with '/rtmp/', and extract the target RTMP URL.

  


  Uncaught TypeError : Cannot read property 'url' of undefined

  


  this is my server.js

  


    let match
  if (!(match = req.url.match(/^\/rtmp\/(.*)$/))) {
    ws.terminate() // No match, reject the connection.
    return
  }
