• PHP-FFMpeg video output is truncated

  25 juin 2019, par showdev

  I’m using the PHP-FFMpeg library found here and code from the "Basic Usage" section.

  The outputted video seems to be truncated. I’m using a source video that’s 28 seconds long, but the output is only 9 seconds. What’s going wrong ?

  Here, I’m checking the duration of the source video :

  $ffprobe = FFMpeg\FFProbe::create();
  
  $duration = $ffprobe
  
    ->format('test/source.mp4')
  
    ->get('duration');

  28.700000

  Then generating an output video :

  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open('test/source.mp4');
  
  $video->save(new FFMpeg\Format\Video\X264(), 'test/export.mp4');

  Then checking the duration of the output video :

  $ffprobe = FFMpeg\FFProbe::create();
  
  $duration = $ffprobe
  
    ->format('test/export.mp4')
  
    ->get('duration');

• Laravel FFMpeg encoding failed [on hold]

  18 février 2019, par Diego Fernández

  I’m using Laravel FFMpeg to encode videos and create thumbnails, but none of them are working. Whenever I try to create a thumbnail or encode a video I get following error :

  ffmpeg failed to execute command '/usr/local/bin/ffmpeg' '-y' '-i' '/home/diego/dynamic4/bg/storage/app/public/activity/4942/cLCbKyLiGqbOb0M5JDtvNXUdzSxFGj9ts6sDZb4D.mp4' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'libfaac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '1' '-passlogfile' '/tmp/ffmpeg-passes5c6378517cace4u1cg/pass-5c6378517cb33' '/home/diego/dynamic4/bg/storage/app/public/1234.mp4'

  If I check that error on console I get this :

  [NULL @ 0x55fecc7a0280] Unable to find a suitable output format for 'failed'
  
  failed: Invalid argument

  I have checked permissions and everything looks ok. I have also checked the video I’m trying to encode exists. It does, and apparently it get properly loaded. It seems to fail when trying to save encoded file.
  I spent one day doing research, I tried with different audio & video encoding, different routes and filesystems, but I couldn’t make it work.
  I have also tried to check that passlogfile (/tmp/ffmpeg-passes5c6377a214b41rk6ao/pass-5c6377a214b7b) but as it gets stored under /tmp I can’t gain access to it.

  This is the code I’m using to encode videos in my controller :

  $folder = 'activity/4942';
  
  $filename = 'cLCbKyLiGqbOb0M5JDtvNXUdzSxFGj9ts6sDZb4D.mp4';
  
  $new_filename = 'storage/activity/4942/1234.mp4'; 
  
  $format = new FFMpeg\Format\Video\X264();
  
  $video = FFMpeg::fromDisk('public')->open($folder . '/' . $filename);
  
  $video->export()->toDisk('public')->inFormat($format)->save($new_filename);

  I have debugged that piece of code and video seems to get loaded properly. It crashes when tries to save the final video, in last lane of code.

  This is the configuration in filesystems.php :

      'disks' => [
  
  
  
          'local' => [
  
              'driver' => 'local',
  
              'root' => storage_path('app'),
  
          ],
  
  
  
          'public' => [
  
              'driver' => 'local',
  
              'root' => storage_path('app/public'),
  
              'visibility' => 'public',
  
          ],
  
  
  
      ],

  Any help much appreciated, thanks !
