• Video streaming to YouTube using JavaScript and Java

  28 septembre 2020, par user1597121

  I'm trying to stream live video from a user's browser to YouTube Live. I already have the following working :

  


  

  1. Capture video from the webcam using navigator.mediaDevices.getUserMedia

  


  2. Send video data to the server via WebSocket by periodically invoking this function :

  


  


  function getFrame(video)
{
    var canvas = document.createElement('canvas');
    canvas.width = video.videoWidth;
    canvas.height = video.videoHeight;
    canvas.getContext('2d').drawImage(video, 0, 0);

    return canvas.toDataURL('image/png', 1);
}


  


  

  3. Creating a live broadcast and stream on YouTube via their API and receiving the RTMP info where they expect the video stream to be sent.

  


  


  This is where I seem to be stuck. I'm not sure how to send the video data from my Java server to YouTube's RTMP endpoint. I've looked into using Red5 or ffmpeg, but haven't been able to find an example where the data is continually being sent via WebSocket. Rather, there's always some "stream" that is being redirected to YouTube, coming in on a dedicated port, or perhaps from a pre-recorded video file.

  


  I have very limited knowledge of how video streaming works, so that's presumably making things more difficult than they should be. I'd really appreciate some help with getting this figured out. Thank you !

• FFmpeg conform DASH to YouTube Live Stream requirements

  4 septembre 2023, par Aniol Pagès

  I'm trying to stream to YouTube using FFmpeg and DASH. I've generated the stream key and I'm successfully sending the generated files to YouTube. However, YouTube refuses the MPD manifest because it has two AdaptationSet (one for video and one for audio), and the documentation specifies that I should use only one for both video and audio

  


  I've tried to use the -adaptation_sets flag unsuccessfully, and also the -map flag.

  


  Here is one of the commands I've tried :
ffmpeg -re -i "/Users/user/Desktop/file.mp4" \        -map 0:v -map 0:a \        -use_template 1 -use_timeline 1 -window_size 5 -min_seg_duration 5000000 \        -f dash dash.mpd

  


  And with the -adaptation_sets flag :
ffmpeg -re -i "/Users/aniolpages/Desktop/2023-09-03 Taller colar filtrar assubtilar.mp4" -map 0 -map 0 -c:a aac -c:v libx264 \ -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash dash.mpd

  


  Has someone been successful to conform the manifest to YouTube requirements ?

  


  Thank you very much !
