• PHP-FFMpeg Error while opening encoder for output stream

  5 janvier 2019, par Valor_

  I’m trying to use this PHP-FFMpeg library, but I’m keep getting errors like

  Error while opening encoder for output stream #0:0

  This is my PHP code

  private function createTeaserVideos($fullVideoPath, $databasePath, $uploadPath) {
  
          $ffmpeg = FFMpeg::create([
  
              'ffmpeg.binaries' => '/usr/bin/ffmpeg',
  
              'ffprobe.binaries' => '/usr/bin/ffprobe',
  
              'timeout'          => 0,
  
          ]);
  
  
  
          $ffmpeg->getFFMpegDriver()->listen(new \Alchemy\BinaryDriver\Listeners\DebugListener());
  
          $ffmpeg->getFFMpegDriver()->on('debug', function ($message) {
  
              var_dump($message);
  
          });
  
  
  
          // Create teaser_video_thumb
  
          $videoNameThumb = $this->randomTimeString() . '-thumb.mp4';
  
          $video = $ffmpeg->open($fullVideoPath);
  
          $video
  
              ->filters()
  
              ->resize(new \FFMpeg\Coordinate\Dimension(400, 280))
  
              ->synchronize();
  
          $video->save(new \FFMpeg\Format\Video\X264('aac', 'libx264'), $uploadPath . $videoNameThumb);
  
      }

  So what I’m trying to do here. User uploads his video and I’m trying to resize it and create one smaller video for the preview. The problem that I’m keep getting it is

  I can’t figure out what is the problem or how to solve it. Can someone please help me out ? I’m using Ubuntu 16 and I have installed ffmpeg via apt-get install ffmpeg.
  If you need any additional infomations, please let me know and I will provide. Thank you

• MP4Box does not create final segment

  5 janvier 2019, par Dhruva

  MP4Box is not creating the final segment of video when I dash it. If I run this command on the command line I get only 15 segments out of 16(there is no error) and running it in Google’s Shaka player gives me a 404 at the end of the video saying that the 16th video segment is not found. I am running MP4Box version 0.5.2.

  MP4Box -dash 4000 -rap -frag-rap -sample-groups-traf -profile dashavc264:live -bs-switching multi -url-template video-700k-encrypted.mp4 video-1000k-encrypted.mp4 video-1500k-encrypted.mp4 video-2000k-encrypted.mp4 audio-encrypted.mp4 -out "dash_protected/manifest.mp4"
