• FFmpeg to Azure Media Services Smooth Streaming Input

  22 juillet 2020, par Adityo Setyonugroho

  I would like to ask about ffmpeg config or command to to mp4 fragment to Azure Media Service live event using smooth streaming / isml protocol. The AMS is not getting any input yet from ffmpeg.
This is my current running command :

  


  ffmpeg -f dshow -i video="Webcam" -movflags isml+frag_keyframe -f isml -r 10 http://endpoint/ingest.isml/streaming1


  


  When I am using RTMP with Wirecast is running well.

  


  Any suggestion on ffmpeg command with isml protocol ?

  


  Thank you

  


• ffmpeg stops pushing stream of h264 frames to the media server after 180s (3 minutes)

  19 décembre 2019, par blvvet

  My purpose is to let tons of h264 frames play on the browser.

  What I try to do is pushing these frames to the node-media-server(I also tried srs, still breaks down at 180s..So I think node-media-server should not be the problem) by ffmpeg and play it on the browser by flv.js. It works fine for the first 180 seconds and It always breaks down at 180s.

  The node process keeps alive after 180s and the node-media-server receives nothing after 180s. So I think the problem may caused on ffmpeg. Since the number is always 180 seconds, I think maybe I did something wrong about the parameters of ffmpeg.

  Thanks to everyone who gives a glance at my question
  Here’s the code from the nodejs side :

  const spawn = require('child_process').spawn
  
  const GET_FRAME = require('XXX') // just a cpp addon to get frame buffer encoded of h264 
  
  let args = [
  
      '-i', 'pipe:0',
  
      '-use_wallclock_as_timestamps', '1',
  
      '-max_delay', '5',
  
      '-r', '25',
  
      '-c', 'copy',
  
      '-preset:v', 'ultrafast',
  
      '-tune:v', 'zerolatency',
  
      '-f', 'flv',
  
      '-g', '5',
  
      'rtmp://127.0.0.1/live/test'
  
  ]
  
  let $ffmpeg = spawn('ffmpeg', args)
  
  setInterval(() => {
  
      let $FrameH264 = GET_FRAME()
  
      console.log($FrameH264) // buffers keep printing after 180s
  
      $ffmpeg.stdin.write($FrameH264)
  
  }, 1000 / 30)

• ffmpeg -i not working when converting media files to mp4

  14 août 2021, par outtobias0x9

  I'm using FFmpeg to convert my media file because It's a free source. But can't figure out how to use it. It takes one and a half hour just to troubleshoot but I totally messed up ! I went here to seek any help (I'm using windows 8.1 OS)

  


  I configure path

  


  command : ffmpeg -i invalid ? why ?

  


  It seems working

  


  i:no such file or directory ?

  


  I even tried New version 2021, but still "Missing argument for option 'i'
