• ffprobe "moov atom not found" on Linux, but works on OS X

  15 mars 2017, par NeuroXc

  I have an MP4 file that I am trying to read info from via ffprobe -print_format json -show_format -show_streams input.mp4. On OS X with the Homebrew-provided FFMpeg 3.2.4, I’m able to read the video information this way. However, on both Debian Stretch and Arch Linux, with FFMpeg 3.2.4 provided through the respective package managers, I am getting :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x55e0b7977120] Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible!
  
  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x55e0b7977120] moov atom not found
  
  input.mp4: Invalid data found when processing input

• aacdec : do not mutate input packet metadata

  aacdec : do not mutate input packet metadata
  Apparently the demuxer outputs the wrong padding for HE-AAC (based on
  
  the raw sample rate, or so). aacdec contains a hack to adjust the muxer
  
  padding accordingly before it’s used to trim the decoder output. This
  
  modified the packet side data, which in combination with the old
  
  decoding API would change the packet the user passed to the decoder.
  
  This is clearly not allowed, and it breaks running some gapless fate
  
  tests with "-fflags +keepside" applied (without keepside, the packet
  
  metadata is typically newly allocated, essentially making a copy and not
  
  modifying the user’s input packet).
  This should probably be fixed in the demuxer (and consequently also the
  
  muxer), but for now only fix the immediate problem.
  Regression since 946ed78f5f8 (2012).

• PHP FFMpeg error ffprobe failed to execute command "ffprobe.exe" "-help" "-loglevel" "quiet"

  5 mars 2017, par Michele

  I’m searching for a way to compress and convert uploaded videos on my site, I’m trying to use FFMpeg with this PHP basic code (on windows) :

  <?php
  
  ini_set('display_errors', 'On'); error_reporting(E_ALL);
  
  require("vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create(array(
  
      'ffmpeg.binaries'  => 'C:/inetpub/wwwroot/FFmpeg/ffmpeg.exe',
  
      'ffprobe.binaries' => 'C:/inetpub/wwwroot/FFmpeg/ffprobe.exe',
  
      'timeout'          => 3600, // The timeout for the underlying process
  
      'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
  
  ));
  
  $video = $ffmpeg->open('input.mp4');
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $video
  
      ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
  
      ->save('frame.jpg');
  
  $video
  
      ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
  
      ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
  
      ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');
  
  ?>

  but I’m getting this error :

  Fatal error: Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffprobe failed to execute command "C:/inetpub/wwwroot/FFmpeg/ffprobe.exe" "-help" "-loglevel" "quiet" in C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\ProcessRunner.php:100 Stack trace: #0 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\ProcessRunner.php(72): Alchemy\BinaryDriver\ProcessRunner->doExecutionFailure('"C:/inetpub/www...') #1 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php(209): Alchemy\BinaryDriver\ProcessRunner->run(Object(Symfony\Component\Process\Process), Object(SplObjectStorage), false) #2 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php(137): Alchemy\BinaryDriver\AbstractBinary->run(Object(Symfony\Component\Process\Process), false, NULL) #3 C:\inetpub\wwwroot\site\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe\OptionsTester.php(61): Alchemy\Binary in C:\inetpub\wwwroot\site\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe\OptionsTester.php on line 63

  what am I doing wrong ? there are better libraries ?
