• FFMPEG fails to stream from .m3u8 over HTTP

  16 mars 2017, par Parsa Samet

  FFMPEG will fail to stream from .m3u8 over HTTP. It is pointing to getting an empty playlist whilst it’s not empty. It also points to the following error sometimes :

  Failed to open segment of playlist 0.

  UPDATE :

  The command that I use :

  ffmpeg -re -i http://cdn.live.domain.tld:port/radio.stream/playlist.m3u8?wmsAuthSign=xyz -vn -codec:a libmp3lame -b:a 64k -f mp3 -content_type audio/mpeg icecast://"source":"password"@destinationIPorDomain:8000/mountPoint

• FFMPEG creating static video ?

  10 juillet 2018, par Kjell

  I’m using ffmpeg 4.0.1 on the latest version of MacOS. I’ve got webcam capture down, as well as creating a video from a series of images. But for some reason, when I try to do screen capture, the outputted video is a bunch of colorful static with the correct audio.

  Here is the command I use :

    ffmpeg -f avfoundation -i '1:0' -y -r 30 -pix_fmt yuv420p test.mp4

  And here are my devices :

  [AVFoundation input device @ 0x7f9924404b00] AVFoundation video devices:

  Anyone have an ideas on how to fix this ?

  I reran the terminal command, let it run for 30s, and then canceled the operation.

  Exiting normally, received signal 2.

  To note : I added -pix_fmt yuv420 because without it, none of my ffmpeg output seems to be able to run via Quicktime Player. Since this is the only player I use currently, I want my output to run on this player. I noticed there is a log about switching to uyvy422, but I think this is a bug because when I manually add uyvy422, the output cannot be opened at all.

• How to stream a screen sharing through a server

  27 mai 2020, par Moaz

  I'm trying to write an application that captures the screen of the client device and streams it (using ffmpeg) to a node-media-server which publishes it as an HLS stream. The stream is then viewed with an HLS player on a web browser (in my approach I used video.js)

  



  What I did so far :

  



  

  • I created a node media server using the default configurations to Remux to HLS live stream in a file called app.js :

  


  



  


  


  const NodeMediaServer = require('node-media-server');

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    mediaroot: './media',
    allow_origin: '*'
  },
  trans: {
    ffmpeg: '/usr/local/bin/ffmpeg',
    tasks: [
      {
        app: 'live',
        hls: true,
        hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
        dash: true,
        dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
      }
    ]
  }
};

var nms = new NodeMediaServer(config)
nms.run();

  


  


  




  

  • I ran it with the command node app.js

  


  • After installing ffmpeg and figuring out which video and audio source I wanted to stream from, I started streaming by running the command :

  


  



  ffmpeg -f avfoundation -framerate 30 -i "1:1" -c:v libx264 -preset superfast -tune zerolatency -c:a aac -ar 44100 -f flv rtmp://localhost/live/STREAM_NAME

  



  

  • I prepared a simple html page which uses the video.js player to play the HLS stream :

  


  



  


  


  &#xD;&#xA;  &#xD;&#xA;&#xD;&#xA;&#xD;&#xA;&#xD;&#xA;  <h1>Video.js Example Embed</h1>&#xD;&#xA;&#xD;&#xA;  &#xD;&#xA;    <p class="vjs-no-js">&#xD;&#xA;      To view this video please enable JavaScript, and consider upgrading to a&#xD;&#xA;      web browser that&#xD;&#xA;      <a href="https://videojs.com/html5-video-support/" target="_blank">supports HTML5 video&#xD;&#xA;    </a></p>&#xD;&#xA;  &#xD;&#xA;  &#xD;&#xA;  <code class="echappe-js">&lt;script src=&quot;https://vjs.zencdn.net/7.8.2/video.js&quot;&gt;&lt;/script&gt;&#xD;&#xA;  &lt;script src=&quot;https://unpkg.com/@videojs/http-streaming/dist/videojs-http-streaming.js&quot;&gt;&lt;/script&gt;&#xD;&#xA;  &#xD;&#xA;  &lt;script&gt;&amp;#xD;&amp;#xA;    var player = videojs(&amp;#x27;my_video_1&amp;#x27;);&amp;#xD;&amp;#xA;    player.src([{&amp;#xD;&amp;#xA;      &quot;type&quot;:&quot;application/x-mpegURL&quot;,&amp;#xD;&amp;#xA;      &quot;src&quot;:&quot;http://localhost:8000/live/STREAM_NAME/index.m3u8&quot;&amp;#xD;&amp;#xA;    }]);&amp;#xD;&amp;#xA;    player.play();&amp;#xD;&amp;#xA;  &lt;/script&gt;&#xD;&#xA;

  


  


  




  

  • then I ran an http server and served this html page to prevent and origin access errors.

  


  • when opening this html page the stream works well in Chrome (v83.0.4103.61)

  


  



  BUT :

  



  


  • In Firefox Developer Edition (v76.0b8 (64-bit)) the player hangs on loading and nothing is shown. It keeps loading the HLS manifest file and the .ts files but the video is not showing :


  


  • In Safari (v13.1) on MacOS the player never loads correctly and the following errors are printed :


  


  



  I tried another video player (flv.js) which workes with http-flv streams using the following basic html page :

  



  


  


  &#xD;&#xA;&#xD;&#xA;&#xD;&#xA;&#xD;&#xA;  <video controls="controls" autoplay="autoplay" muted="muted" width="640" height="268"></video>&#xD;&#xA;&#xD;&#xA;  <code class="echappe-js">&lt;script src=&quot;https://cdn.bootcss.com/flv.js/1.5.0/flv.min.js&quot;&gt;&lt;/script&gt;&#xD;&#xA;  &lt;script&gt;&amp;#xD;&amp;#xA;      if (flvjs.isSupported()) {&amp;#xD;&amp;#xA;          var videoElement = document.getElementById(&amp;#x27;flvPlayer&amp;#x27;);&amp;#xD;&amp;#xA;          var flvPlayer = flvjs.createPlayer({&amp;#xD;&amp;#xA;              type: &amp;#x27;flv&amp;#x27;,&amp;#xD;&amp;#xA;              &quot;isLive&quot;: true,&amp;#xD;&amp;#xA;              url: &amp;#x27;http://localhost:8000/live/STREAM_NAME.flv&amp;#x27;&amp;#xD;&amp;#xA;          });&amp;#xD;&amp;#xA;          flvPlayer.attachMediaElement(videoElement);&amp;#xD;&amp;#xA;          flvPlayer.load();&amp;#xD;&amp;#xA;          flvPlayer.play();&amp;#xD;&amp;#xA;      }&amp;#xD;&amp;#xA;  &lt;/script&gt; &#xD;&#xA;&#xD;&#xA;

  


  


  




  

  • It worked as expected in Chrome

  


  



  BUT :

  



  


  • On Firefox it plays an empty video with some noise showing the following warnings :


  


  • And on Safari it doesn't play at all and shows the following error : 


  


  



  I also tried the same steps on IE11 and on Edge and it also didn't work (Unfortunately, I don't have any screenshots)

  



  So my questions are : what am I doing wrong ? why didn't each approach work ? and are there other/better approaches that I can also try which helps achiving the same goal (preferably something free/open source with as least latency as possible)
