• How do I close a Node.js FFMPEG child process that is actively streaming from a live capture source ?

  1er juin 2013, par RickZ

  I'm new to Node.js and have figured out how to utilize child.spawn to launch an instance of FFMPEG that is being used to capture live video and send it over to Adobe Media Server via rtmp.

  Every example I've seen of FFMPEG being used in conjunction with Node.js has been with a time limited sample, so the child process closes once FFMPEG reaches the end of the file it is converting.

  In this case, there is no "end of file".

  If I instantiate :

      var ffmpeg = child.spawn('ffmpeg.exe', [args]);

  it creates the live feed.

  I have tried immediately shutting the child process down with a :

      setTimeout(function() {
  
          ffmpeg.stdin.resume();
  
          ffmpeg.stdin.write('insert command to echo q to close FFMPEG');
  
          ffmpeg.stdin.end();
  
      });

  However, that does not seem to work. I continue to see my rtmp feed on my test box.

  Is there any way to pass FFMPEG a shut down command via stdin in Node.js ?

  Thanks in advance !

• child process spawn output file and directory in NodeJs

  5 juin 2021, par Zeeshan

  I am using ffmpeg with child process to merge audio and video, but when i am trying to download the file, it is downloading in the same folder, but i want it to download it in the public folder.

  


  following is my code for the child process spawn.

  


  // Start the ffmpeg child process
const ffmpegProcess = cp.spawn(ffmpeg, [
    // Remove ffmpeg's console spamming
    '-loglevel', '8', '-hide_banner',
    // Redirect/Enable progress messages
    '-progress', 'pipe:3',
    // Set inputs
    '-i', 'pipe:4',
    '-i', 'pipe:5',
    // Map audio & video from streams
    '-map', '0:a',
    '-map', '1:v',
    // Keep encoding
    '-c:v', 'copy',
    // Define output file
    'title.mp4',
], {
    windowsHide: true,
    stdio: [
        /* Standard: stdin, stdout, stderr */
        'inherit', 'inherit', 'inherit',
        /* Custom: pipe:3, pipe:4, pipe:5 */
        'pipe', 'pipe', 'pipe',
    ],
});
