• 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 !

• Discord.js Music Bot ffmpeg not found ?

  13 octobre 2020, par cccmdm

  I just started learning javascript with node.js and I am attempting to create a music bot, I've set up the command handler and everything, however, I keep getting this error when I try to run the play command

  



  


  Error : FFmpeg/avconv not found !

  I'll post my play function below

  



  async function playMusic(vc,songId) {
    const stream = await ytdl(songId,{type: 'opus',filter : 'audioonly'});
    vc.join().then(connection => {
        const dispatcher = connection.play(stream,{volume: 1});
        dispatcher.on('end', end => {
            console.log("Song ended!");
            vc.leave();
        }).catch(err => console.log(err));
    }).catch(err => console.log(err));
}
