• FFmpeg Video Not Showing But I Hear the Sound

  14 janvier 2019, par Supercoder54551

  I am using ffmpeg to convert my videos, and I thought everything was fine but I ran into a problem. When I go on my tablet to play the video, the video does not show but I hear the sound. Here’s my code, thanks in advance.

  $vid = $request->file('video');
  
  $filename = uniqid() . $vid->getClientOriginalName();
  
  
  
  $request->video->move(public_path('/app'), $filename);
  
  $name_file = uniqid() . 'intro_video.mp4';
  
  
  
  $ffp = FFMpeg::open($filename)
  
      ->addFilter(function ($filters) {
  
          $filters->resize(new \FFMpeg\Coordinate\Dimension(640, 640));
  
      })
  
      ->export()
  
      ->toDisk('s3')
  
      ->inFormat(new \FFMpeg\Format\Video\X264('libfdk_aac', 'libx264'))
  
      ->save($name_file);
  
  
  
  $imageName = Storage::disk('s3')->url($name_file);
