• ffmpeg - Live stream to web browser [on hold]

  21 octobre 2016, par Sreejith C M

  I was looking for a solution to stream my desktop live on my Windows system and found out ffmpeg is a good solution using dshow and everything is working fine and well. I’m using a C# wrapper for ffmpeg to record my desktop and I can save it in a local file.

  The problem I have is that, I have to watch the stream on my Web browser ( Chrome / Firefox ). I can’t use Media Server’s like wowza, red5 and also can’t use ffserver.

  I tried the ffmpeg wiki https://trac.ffmpeg.org/wiki and documentation but couldn’t figure out how to do this.

  Please help me to figure out this, how I can do this.

• Live streaming multiple bitrates with FFmpeg and node.js

  14 juillet 2014, par user2757842

  I am looking for an efficient way of transcoding a live stream and breaking it up into different bit rates, I have it working as of now but I have to state each time which video I would like to address as well as each different bit rate, example below :

  var spawn = require('child_process').spawn;
  
  
  
  /*
  
  var ffmpeg = spawn('C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe', [
  
      '-i',
  
      'rtmp://192.168.201.8/livepkgr/livestream2 live=1',
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming.isml/Streams(video2)'
  
  ]);
  
  */
  
  
  
  var ffmpeg = spawn('C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe', [
  
      '-i',
  
      'rtmp://192.168.201.8/livepkgr/livestream live=1',
  
      '-ac',
  
      '2',
  
      '-b:a',
  
      '64k',
  
      '-c:v',
  
      'libx264',
  
      '-b:v:0',
  
      '150k' /* first bit rate i want */ ,
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming2.isml/Streams(video1)',
  
      '-c:v',
  
      'libx264',
  
      '-b:v:0',
  
      '500k' /* second bit rate i want */ ,
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming2.isml/Streams(video3)'
  
  ]);

  As you can see, this is not a very efficient way of doing it as this is only for 2 bit rates, I have to give a video name (video1, video 3 etc) each time I want a new bit rate and then I have to give it it’s bit rate (150k, 500k etc). If I wanted anymore bitrates, the code lines would go on and on and it would quickly become messy.

  Has anyone worked within the world of Node.js and FFmpeg that could maybe point me in the direction of managing this more efficiently ? Or even link me to a page which would help me out ?

  Cheers

• ffmpeg - Recording live stream

  16 novembre 2016, par arpak

  I try to record 59 minutes from live hls(m3u8) link

  ffmpeg -i http://example.com/video.m3u8 -t 3420 -c copy -y -hls_playlist_type vod /var/www/html/recording/rec1.m3u8

  So it works But if there is a network problem with input link for few seconds it stop the recording.

  Is there a way to make the ffmpeg wait for input link and then contiue recording without killing the ffmpeg

  so i read about timeout but dont know exactly how to make it.
  so maybe ffmpeg can wait for input link and then continue to record after it is available or maybe display image when first input is down, so whatever solution is acceptable just not to kill ffmpeg if input source is down
