• Streaming a programatically created video to youtube using node and ffmpeg

  23 septembre 2020, par Caltrop

  I've been trying to Livestream a programmatically created image to youtube using node. I've had very limited success using FFmpeg. While I have managed to create and save an image thanks to this insightful thread, I have yet to make the code work for streaming to an RTMP server.

  


  const cp = require('child_process'),
    destination = 'rtmp://a.rtmp.youtube.com/live2/[redacted]', //stream token redacted
    proc = cp.spawn('./ffmpeg/bin/ffmpeg.exe', [
        '-f', 'rawvideo',
        '-pix_fmt', 'rgb24',
        '-s', '426x240',
        '-i', '-', //allow us to insert a buffer through stdin
        '-f', 'flv',
        destination
    ]);

proc.stderr.pipe(process.stdout);

(function loop() {
    setTimeout(loop, 1000 / 30); //run loop at 30 fps
    const data = Array.from({length: 426 * 240 * 4}, () => ~~(Math.random() * 0xff)); //create array with random data
    proc.stdin.write(Buffer.from(data)); //convert array to buffer and send it to ffmpeg
})();


  


  When running this code no errors appear and everything appears to be working, however, YouTube reports that no data is being received. Does anybody know what is going wrong here ?

  


  Update : This is really counter-intuitive but adding a slash to the destination like this 'rtmp://a.rtmp.youtube.com/live2/[redacted]/' causes ffmpeg to throw a generic I/O error. This is really weird to me. Apologies if the answer to this is obvious, I'm really inexperienced with ffmpeg.
