• FFMPEG : 2x2 Grid Cameras stream to Youtube

  8 avril 2021, par Martin

  So this is my "working" ffmpeg command :

  


  ffmpeg -rtsp_transport tcp -i "input1" -rtsp_transport tcp -i "input2" -rtsp_transport tcp -i "input3" -rtsp_transport tcp -i "input4" -filter_complex "[0:v] setpts=PTS-STARTPTS, scale=480x270 [a0];[1:v] setpts=PTS-STARTPTS, scale=480x270 [a1];[2:v] setpts=PTS-STARTPTS, scale=480x270 [a2];[3:v] setpts=PTS-STARTPTS, scale=480x270 [a3];[a0][a1][a2][a3]xstack=inputs=4:layout=0_0|0_h0|w0_0|w0_h0[out]" -map "[out]" -map 3:a -video_size 1920x1080 -tune zerolatency -profile:v baseline -level 3.0 -b:v 5000k -vcodec libx264 -preset medium -q:v 3 -crf 15 -r 15 -c:a aac -ac 2 -f flv rtmp://a.rtmp.youtube.com/live2/...

  


  The problem that i have is that the Youtube recognize this stream as only "360p" and i think that the quality of each stream is way worst than these cameras really are.

  


  Is there something that i'm doing wrong or it should "work" like that because of scalling it to 2x2 grid ?

  


• 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.
