• Live Streaming over HTTP using CloudFront and FFMPEG having delay issue

  23 avril 2021, par jitendra-gautam

  Live Streaming using CloudFront and FFMPEG having delay issue I am using the NodeJS server with FFMPEG and live streaming to CloudFront, which is then consumed by many people via CloudFront. Below is the data received at the user's end.

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:1317
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:1
#EXTINF:0.833333,
1317.ts
#EXTINF:0.833333,
1318.ts
#EXTINF:0.833333,
1319.ts


  


  The problem is the next .ts file that is 1320.ts is taking time to create on the server, thus the user is seeing the loading sign, and when this 1320.ts is created on the server, thereafter only the user is able to see the next live stream frame. How can the streaming be continuous ?? Below is the FFMPEG command that is being used :

  


  process = child_process.spawn('ffmpeg', commandArgs);



  


  let commandArgs = [
  '-loglevel',
  'debug',
  '-protocol_whitelist',
  'pipe,udp,rtp,rtmp,http,https,tcp',
  '-fflags',
  '+genpts',
  '-f',
  'sdp',
  '-i',
  'pipe:0',
  '-c:v',
  'libx264',
  '-crf',
  '21',
  '-preset',
  'veryfast',
  '-g',

];



  


• Any alternative of Ffmpeg for Youtube live streaming app ?

  26 avril 2017, par samir.k433

  In this youtube live streaming app they are using Ffmpeg for encoding audio and video, and then for streaming to server. It’s somehow complex for me (specifically the build tasks).
  Is there any alternative instead of using Ffmpeg in this regard ?

• Mac App (Cocoa) for producing HTTP Live Streaming

  11 mars 2013, par Michael

  I am building a Mac OS X application (Cocoa) with XCode that captures a video source and outputs the video through HTTP Live Streaming (HLS). After doing a fair amount of research I am thinking that I should be able to use the following stack of elements in my app to make this happen...

  • AVCaptureDevice
  • AVCaptureSession
  • AVCaptureVideoDataOutput
  • FFMPEG
  • mediastreamsegmenter
  • CocoaHTTPServer

  I would really appreciate some feedback as to whether I'm on the right track, or correction if I am mistaken. Obviously any advice, pointers, perhaps some sample code snippets would be so very helpful.

  Many thanks in advance !
