• Unable to load FFProbe driver for FFmpeg

  12 septembre 2021, par Kapil Ropalekar

  Hi i am trying to install php-ffmpeg.
  Can someone guide me or correct me in my steps.

  



  


  1. I installed the composer on windows and then traversed to my folder i had created to run install ffmpeg cmd

  


  2. After running this command a composer.json, composer.lock file were created along with a vendor folder.

  


  3. Later installed the Shared FFMpeg build for 64bit from here

     



     


     http://ffmpeg.zeranoe.com/builds/

     


  


  



  and form this folder copied the bin folder to my directory to set the ffmpeg and ffprobe path during create() like this

  



  $ffmpeg = \FFMpeg\FFMpeg::create([
    'ffmpeg.binaries'  => '/vendor/bin/ffmpeg.exe',
    'ffprobe.binaries' => '/vendor/bin/ffprobe.exe' 
]);


  



  Currently i am getting this error which says :

  



  "Fatal error: Uncaught exception 'Alchemy\BinaryDriver\Exception\ExecutableNotFoundException' with message 'Executable not found, proposed : /vendor/bin/' in D:\xampp\htdocs\health\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php:160 Stack trace: #0 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php(48): Alchemy\BinaryDriver\AbstractBinary::load('/vendor/bin/', NULL, Object(Alchemy\BinaryDriver\Configuration)) #1 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php(207): FFMpeg\Driver\FFProbeDriver::create(Array, NULL) #2 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFMpeg.php(117): FFMpeg\FFProbe::create(Array, NULL, NULL) #3 D:\xampp\htdocs\health\ff.php(6): FFMpeg\FFMpeg::create(Array) #4 {main} Next exception 'FFMpeg\Exception\ExecutableNotFoundException' with message 'Unable to load FFProbe' in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php:50 Stack trace: #0 D:\xampp\htdocs\he in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php on line 50".


  



  So what could i have done wrong or am i missing any steps. Can someone point me to the right direction.

  lavc/vaapi_encode : Don't return error if the underlying driver doesn't support B frames
  The underlying driver need not support B frames - since they are enabled
  
  by default for some codecs, it is better to disable them rather than
  
  returning an error in this case.  This makes the default settings usable
  
  for low-power encoding on Intel platforms.
