• ffmpeg throwing "Output file #0 does not contain any stream" when trying to make a slideshow out of images

  27 juillet 2020, par Abdou Tahiri

  Im trying to create video streaming using phantomjs that create screenshots from a url then it will pipe the frames to ffmpeg so he can use it to stream the video to an rtmp url .
here is what i tried so far :

  



  phantomjs runner.js | ffmpeg -f image2pipe  -vcodec png -c:a copy -c:v libx264  -f flv rtmp://localhost/mystream


  



  and here is the script :

  



  var page = require('webpage').create();
page.viewportSize = { width: 640, height: 480 };

page.open('http://www.goodboydigital.com/pixijs/examples/12-2/', function () {
  setInterval(function() {
    page.render('/dev/stdout', { format: "png" });
  }, 25);
});


  



  and this is the output :

• Streaming a WebPage to YouTube using FFMpeg

  30 mars 2020, par Pedro Lobito

  I’m trying to stream a webpage to YouTube using phantomjs and ffmpeg.
  Long question short :

  This works. The video is saved to test.flv :

  phantomjs runner.js|ffmpeg -y -f image2pipe -r 10 -s 1280x720 -i - -deinterlace -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -r 10 -g 20 -vb 400k -maxrate 400k -minrate 400k -bufsize 800k -threads 6 -q:v 0 -t 10 -f flv test.flv

  This doesn’t. Despite no errors, nothing is streamed to YouTube.

  phantomjs runner.js|ffmpeg -f image2pipe -r 10 -s 1280x720 -i - -deinterlace -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -r 10 -g 2 -vb 400k -maxrate 400k -minrate 400k -bufsize 800k -threads 6 -q:v 0 -f flv rtmp://a.rtmp.youtube.com/live2/xxxxxxx

  ---

  Remarks :

  1. I’m aware phantomjs isn’t actively developed anymore, but this doesn’t seem
     relevant since the phantomjs script works as intended ;
  2. phantomjs script : runner.js ;
  3. I’ve tried different ffmpeg settings, like frame-rates, bit-rates and bufsize to no avail.
  4. Both commands are similar, but the 1st outputs to local-file test.flv while 2nd to YouTube ;
  5. I’ve used the YouTube streaming key on OBS Studio and it works normally ;
  6. ffmpeg output while streaming to YouTube :

  frame=   13 fps=0.0 q=42.0 size=      94kB time=00:00:00.50 bitrate=1531.0kbits/                                                                   frame=   18 fps= 16 q=40.0 size=     130kB time=00:00:01.00 bitrate=1063.6kbits/                                                                   frame=   23 fps= 14 q=44.0 size=     149kB time=00:00:01.50 bitrate= 810.8kbits/

  7. ffmpeg version 4.2.1-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2000-2019 the FFmpeg developers running on Ubuntu-1804

  Any idea of what can be wrong ?
