• 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 !

• avcodec/nvenc : add high bit depth encoding for HEVC

  avcodec/nvenc : add high bit depth encoding for HEVC
  Adding 10-bit encoding support for HEVC if the input is 8-bit. In
  
  case of 8-bit input content, NVENC performs an internal CUDA 8 to
  
  10-bit conversion of the input prior to encoding. Currently, only
  
  AV1 supports encoding 8-bit content as 10-bit.

• w32pthreads : always use Vista+ API, drop XP support

  w32pthreads : always use Vista+ API, drop XP support
  This removes the XP compatibility code, and switches entirely to SRW
  
  locks, which are available starting at Windows Vista.
  This removes CRITICAL_SECTION use, which allows us to add
  
  PTHREAD_MUTEX_INITIALIZER, which will be useful later.
  Windows XP is hereby not a supported build target anymore.
