• fastest way to convert .MKV files to HTTP Live Streaming (HLS)

  22 septembre 2017, par Oli

  Can anyone advise on how to convert .mkv files to HLS format ? we have lots of .mkv files and we are going to lunch our live streaming website so we decided to programatically convert our files to HLS format. we tried ffmpeg and vodobox HLS encoder for conversion but both are too slow (about 1.5 h for each movie).

  platform information :

  • OS : Windows 10
  • CPU : Intel Core i5
  • Memory : 16 GB DDR4

  I am using ffmpeg to create an mp4 file on my server. I am also trying to use qt fast start to be able to move the moov atom to the front so it will stream. I have searched all over the internet with no luck. Is it possible to put my video/audio in a mp4 buffer type file and then be able to play it while ffmpeg is still dumping video and audio data into the stream ? the point is I am trying to stream from a camera and Android is horrid... I know both ios and android support mp4 so I was trying to figure a way I can make my rtsp Mp4.

  main point of the story : I want to continuously feed my mp4 container my camera feed and still be able to playback the file os my clients can watch.

  any help appreciated thank you.

  Prologue :

  


  I have a hikvision ipcamera that streams raw h264 from a rtsp :// url, I need to play this live feed in the browser.

  


  I managed to get a basic RTSP->ffmpeg-> (faststart) mp4 pipeline working and I can play the video when saved to a file.

  


  I don't understand how to make my controller action "streamable".

  


  I've tried various approaches like writing to Response.Body, Transfer-Encoding : chunked but nothing seems to work.
Here is the basic code :

  


  public IActionResult Play5(){    
      var ms = new MemoryStream();
      var muxer = new RTSPToMp4(ms);
      Task.Run(() => muxer.Stream());
      return new FileStreamResult(ms, "video/mp4");
}


  


  The memory stream contains the live feed but the response is empty here is the request\response from chrome :
