• using ffmpeg to stream a live video file, which is continuously being updated

  20 juin 2022, par tamirg

  I have one process that gets a live stream from a source, and can write it to a file. Meaning the file will keep updating with new frames data from the stream.

  


  Is this possible to make this file an input for ffmpeg process, so ill get a live stream from this file ? (i wouldn't want it to stream it in a loop, but only to stream live the "new" data)

  


• Queuing multiple video files as a single live video stream with nodejs and ffmpeg

  24 avril 2016, par bomtempi

  i would like to stream a video with node nodejs using multiple little video sequences that are created on the fly.
  It means that the server queues multiple files, but the client must see it as only one single stream.

  Why would i need such feature ?

  I have an application that creates images on the fly on the server, and i need to send them as a single video to the client, as if it was on a live source.
  I cannot use ffmpeg to concatenate these files and convert them to a single video because i don’t have the complete sequence.

  I can do the trick with images sequences, using "multipart/x-mixed-replace" content-type, in a mjpeg format. Here is how i do :

  http.createServer(function(req, stream) {
  
    stream.writeHead(200, {
  
      'Content-Type': 'multipart/x-mixed-replace;boundary=myboundary',
  
      'Cache-Control': 'no-cache',
  
      'Expires': '-1',
  
      'Connection': 'close',
  
      'Pragma': 'no-cache'
  
    });
  
  
  
    setInterval(function() {
  
  
  
      var data = ... // here launch the function to get the binary data from the latest image created on the server
  
  
  
      stream.write("--myboundary\r\n");
  
      stream.write("Content-Type: image/jpeg\r\n");
  
      stream.write("Content-Length: " + data.length + "\r\n");
  
      stream.write("\r\n");
  
      stream.write(data);
  
      stream.write("\r\n");
  
    }, 300);
  
  
  
  }).listen(port, function() {
  
  
  
  });

  The problem with this format is that it has no sound.
  I tried to serve the sound from a different endpoint, and use ffmpeg to assemble them in live and send them back to the server where it will be forwarded to a new endpoint containing the sound and video, but after just a few seconds the video becomes more and more laggy and freezes.

  So that is why i thought that i should start by generating small videos on the server, by taking the 24 or 30 latest images created on the fly, concatenate them with ffmpeg and queue them on nodejs. That would just add approximately 1 second delay to the client.

  Thanks for your help !
