• 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 ?

• Vitamio Media Player License Requirements

  27 mai 2015, par Amanda Fernandez

  I have successfully integrated vitamio project in my app and it works perfectly. But I’m not clear about its licence. I found the project in github. It uses ffmpeg library and some of the files have apache license. So can I use, vitamio for enterprise app without the license ? Or license is mandatory. ?
