• ffmpeg fluent live streaming to youtube not working

  18 octobre 2020, par Ricky

  I am learning how to using ffmpeg fluent and I am having trouble getting it to stream live to Youtube

  



  here is the command I have tried :

  



  let streamYT = (YTrtmpKey) => {
  var proc3 = new ffmpeg({ source: inputURL, timeout: 0 })
    .addOption('-vcodec', 'libx264')
    .addOption('-acodec', 'aac')
    .addOption('-crf', 26)
    .addOption('-aspect', '640:360')
    .withSize('640x360')
    .on('start', function(commandLine) {
    console.log('Query : ' + commandLine);
    })
    .on('error', function(err) {
    console.log('Error: ' + err.message);
    })
    .output('rtmp://a.rtmp.youtube.com/live2/' + YTrtmpKey, function(stdout, stderr) {
    console.log('Convert complete' +stdout);
  });
  }


  



  this doesn't throw any errors but also doesn't do anything

  


• How do I make youtube-dl or streamlink stop after a certain period of time when downloading a live stream

  13 janvier 2020, par Programmer4Life

  I’m the unofficial historian for a popular 24/7 live feed. I wrote a script to use streamlink (fork of livestreamer) to download the stream constantly. Then i have a script to upload the captured video to YouTube as unlisted for the stream owner. I use a shell script and have the file names be dates and times.

  I’ve also used youtube-dl. For both, The maximum captured time appears to be 6 hours because it’ll stop after that amount of time. To address this, I wrote a script to restart the capture when it stops after sleeping for 30 seconds (safety in case of runaway loop) so this isn’t an issue either.

  What i am trying to do is to either set my stream capture (whether it’s youtube-dl or streamlink it doesn’t matter) to stop after a shorter interval, say 2 hours. I could also split up the file into 3 parts but i don’t know if that would require re-encoding. If it does, that’s not an option because all of this is done on a VPS with limited resources.

  The reason I am trying to split up the files or capture in a shorter time period is because 6 hours is too dang long to easily navigate a YouTube video. On mobile, trying to seek to a specific time is near impossible. Desktop isn’t much easier because you need to be very precise.

• When using youtube-dl with ffmpeg, what merge extension(mkv/mp4) can get best sound quality

  16 mars 2021, par jokerme

  I use youtube-dl -F to display all video/audio list, and choose best video/audio source myself.

  


  Then I use youtube-dl -f [video code]+[audio code] to download and automatically merge them.

  


  As question title, when I use —merge-output-format, what output extension should be chosen then I can get a file with best sound quality. Is mkv ? Or is most suitable merge extension related to the extension of video/audio source ?

  


  By the way, my using player is PotPlayer.
