• Using ffmpeg to stream to Facebook Live Video : with default webcam and mic

  16 septembre 2017, par suraj kiran

  i tried commands like this
  ffmpeg -i /dev/video0 -vf scale=320:240 -t 5400 -c:a copy -ac 1 -ar 44100 -b:a 128k -c:v libx264 -pix_fmt yuv420p -r 30 -g 60 -vb 2048k -minrate 2000k -maxrate 4000k -bufsize 4096k -f pulse flv "rtmp://live-api-a.facebook.com:80/rtmp/279340769232610?ds=1&s_l=1&a=AThKJag2wqGSJkDI"
  but all those resulted as streaming in ffmpeg but no video appears on facebbok.
  can anyone provide correct command for ffmpeg to stream with my webcam and mic. i prefer low quality video stream(about 360p) due to my poor network

• 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).

  • OS : Windows 10

• Live streaming multiple bitrates with FFmpeg and node.js

  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
