• How to stream 24/7 on youtube (audio + video) with FFMPEG

  29 septembre 2023, par Carter510

  I plan to create a 24/7 stream with a video and a musical background which is located in a /Playlist folder.
I would like the music playlist to be played randomly and if a piece of music is corrupted or cannot be played, the program moves on to the next one.

  


  The problem is that with my command every time the music changes the stream stops.
Any suggestions ?

  


  #!/bin/bash

VBR="4500k"
FPS="30"
QUAL="superfast"

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="XXXX-XXXX-XXXX-XXXX"

VIDEO_SOURCE="fireplace.mkv"
AUDIO_FOLDER="/home/administrateur/Documents/Youtube/Playlist"

while true; do
    # Joue la vidéo en boucle
    ffmpeg -re -stream_loop -1 -i "$VIDEO_SOURCE" \
    -thread_queue_size 512 -i "$(find "$AUDIO_FOLDER" -type f -name "*.mp3" | shuf -n 1)" \
    -map 0:v:0 -map 1:a:0 \
    -map_metadata:g 1:g \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 6 -qscale:v 3 -b:a 320000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"
done


  


  I would like the fireplace.mkv video to play without interruption, for the music to be chosen randomly without ever stopping. And if one of the songs cannot be played, it is skipped.

  


• ffmpeg - stream_loop mp3 + looping video (per track)

  5 mars 2023, par cYberSport91

  I'm using ffmpeg to create a livestream video playlist of a folder of mp3s and a folder of videos.

  



  I'd like everytime a new song comes on a new video loops until the next song.

  



  Initially I was using live-stream-radio which is perfect except how it's handled is after every track a new ffmpeg stream loop is initialized. And in a lot of clients this issues a stop command, and there's "dead space" between.

  



  My attempt was when creating the gif playlist text file (they were gifs but I converted to mp4), I set the duration for the duration of the corresponding track. The problem is the video plays once, and then freezes on the final frame until the next track.

  



  rm music.txt
rm gifs.txt
printf "ffconcat version 1.0\n" >> gifs.txt
printf "ffconcat version 1.0\n" >> music.txt
for i in {1..9}; do
  printf "file 'mp3/00%s.mp3'\n" $i >> music.txt
done

for i in {1..9}; do
  DURATION=$(ffmpeg -i mp3/00$i.mp3 2>&1 | awk '/Duration/ { print substr($2,0,length($2)-1) }')
  printf "file 'gif/00%s.mp4'\nduration %s\n" $i $DURATION >> gifs.txt
done

ffmpeg \
    -stream_loop -1 \
    -i gifs.txt \
    -i music.txt \
    -vcodec libx264 \
    -f flv "$URL"


  



  Any ideas here would be great.

  


• Fluent-ffmpeg : merging video and audio = wrong frames

  5 juin 2015, par rhanb

  I’m trying to merge a video (mp4) without audio stream with an audio file (mp3). I’m developing under nodewebkit a video software which means that I have to use ogg files, so when the user upload a video or a audio file it converts it in ogg whatever its format. Then when the user want to export its video I’m exporting frames from a canvas to PNG images. Once this is done I’m creating a video from the frames with a 30 fps with this following code :

  var videoMaker = function () {
  
  
  
      console.log('videoMaker');
  
  
  
      var deffered = Q.defer();
  
      if (!FS.existsSync($rootScope.project.path + '/video')) {
  
          filestorageService.createFolder($rootScope.project.path + '/video');
  
      }
  
      audioMaker().then(function () {
  
          var commandVideo = new Ffmpeg({
  
              source: $rootScope.project.path + '/frames/%d.png'
  
          });
  
          commandVideo.setFfmpegPath(ffmpegPath);
  
          commandVideo.addOptions(['-c:v libx264', '-r 30']).withFpsInput(30).format('mp4').on('error', function (err) {
  
              console.log('video', err);
  
          }).on('end', function () {
  
              console.log('video win');
  
              deffered.resolve();
  
          }).save($rootScope.project.path + '/video/rendu.mp4');
  
      });
  
      return deffered.promise;
  
  };

  Then i’m reconverting the audio wich has been uploaded by the user to mp3 :

  var audioMaker = function () {
  
  
  
      console.log('audioMaker');
  
      var deffered = Q.defer();
  
      if ($rootScope.project.settings.music.path !== '') {
  
          FS.writeFileSync($rootScope.project.path + '/music/finalMusic.mp3', null);
  
          var commandAudio = new Ffmpeg({
  
              source: $rootScope.project.settings.music.path
  
          });
  
          commandAudio.setFfmpegPath(ffmpegPath);
  
          if ($rootScope.project.settings.music.fadeIn) {
  
              commandAudio.audioFilters('afade=t=in:ss=0:d=0.5');
  
          }
  
          console.log($rootScope.project.settings.music.fadeOut, $rootScope.project.settings.music.fadeIn);
  
          if ($rootScope.project.settings.music.fadeOut) {
  
              var time = sceneService.getTotalDuration() - 0.5;
  
              commandAudio.audioFilters('afade=t=out:st=' + time + ':d=0.5');
  
          }
  
          commandAudio.toFormat('mp3').on('end', function () {
  
              console.log('audio win');
  
              deffered.resolve();
  
          }).on('error', function (err) {
  
              console.log('audio', err);
  
          }).save($rootScope.project.path + '/music/finalMusic.mp3');
  
      } else {
  
          deffered.resolve();
  
      }
  
      return deffered.promise;
  
  };

  Until there everything is alright those files work well but when i do this :

  var command = new Ffmpeg({
  
      source: $rootScope.project.path + '/video/rendu.mp4'
  
  });
  
  command.setFfmpegPath(ffmpegPath);
  
  console.log($rootScope.project.settings.music.path !== '');
  
  if ($rootScope.project.settings.music.path !== '') {
  
      command.addInput($rootScope.project.path + '/music/finalMusic.mp3');
  
      command.addOptions(['-c:v copy', '-c:a copy']);
  
      if ($rootScope.project.settings.music.duration > sceneService.getTotalDuration()) {
  
          command.addOptions(['-shortest']);
  
      }
  
      command.on('error', function (err) {
  
          console.log(err);
  
      }).on('end', function () {
  
          console.log("win");
  
          //filestorageService.rmFolder($rootScope.project.path + '/frames');
  
      }).save($rootScope.project.path + '/video/rendu.mp4');
  
  } else {
  
      filestorageService.rmFolder($rootScope.project.path + '/frames');
  
  }

  And my final file has the music and the right duration but the frames aren’t right, any ideas ?
