• Passing stream of getUserMedia output to ffmpeg,How would i do that ?

  1er octobre 2018, par A Sahra

  I am using getUserMedia to get access to camera.while playing the captured video with getUserMedia. I want to stream and broadcast it to all user in my page as Live stream using ffmpeg and ffserver.

  How would I post that stream to server(ffserver) for streaming it live ?

  Here is the code for getUserMedia part

  window.addEventListener('DOMContentLoaded', function() {
  
    var v = document.getElementById('vlive');
  
    navigator.getUserMedia = (navigator.getUserMedia || navigator.webkitGetUserMedia 
  
     || navigator.mozGetUserMedia || navigator.msGetUserMedia);
  
    if (navigator.getUserMedia) {
  
      navigator.getUserMedia({
  
          video: true,
  
          audio: true,
  
        },
  
        function(stream) {
  
          var url = window.URL || window.webkitURL;
  
          v.src = url ? url.createObjectURL(stream) : stream;
  
          v.play();
  
        },
  
        function(error) {
  
          console.log('Good Job');
  
          alert('Something went wrong. (error code ' + error.code + ')');
  
          return;
  
        });
  
    } else {
  
      alert('Sorry, the browser you are using doesn\'t support getUserMedia');
  
      return;
  
    }
  
  });

• ffmpeg generate overlay complex filter for audio with background image

  8 janvier 2016, par user1793606

  I am experimenting with ffmpeg and would like to generate overlay complex filter for audio with background image. The code normally works, except for when adding -filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a
  it crashes. I found the example code at https://trac.ffmpeg.org/wiki/Waveform Any help is appreciated.

  Command '['c:/ffmpeg/bin\\ffmpeg.exe', '-y', '-loop', '1', '-r', '1', '-i', 'temp\\bg.png', '-i', 'test.mp3', '-filter_complex', '[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]', '-map', '[v]', '-map', '0:a', '-c:v', 'libx264', '-preset', 'ultrafast', '-tune', 'stillimage', '-crf', '15', '-pix_fmt', 'yuv420p', '-strict', 'experimental', '-c:a', 'aac', '-b:a', '256k', '-shortest', '-threads', '0', 'done/test.mp4']'

  EDIT 1 :

  I tested this with the new verson : ffmpeg -y -i input.mp3 -i background.png -filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a -c:v libx264 -c:a copy output.mp4

  It generates an output file, but only the waveform, no background included. My end goal is to generate the waveform over the background.
