• 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".

• ffpmeg extracting frames produces too many images

  7 septembre 2019, par Abishur

  I’m using FFMpeg to extract some png files from a video using the following command :

  ffmpeg -i FILE.mp4 -vf "select=not(mod(n\,75))" -vsync vfr img_%03d.png 

  the source video has a duration of 2898 seconds and a framerate of 25 FPS. This means I should be grabbing a picture every 3 seconds for 966 pictures.

  However, instead I’m getting 1158 pictures. After doing some math I’ve discovered that that is the within 2 pictures of what I would expect if I was grabbing the 75th frame from a 30 FPS video.

  I’ve tried -framerate=25 but it still produces the same amount of pictures. The video does have a variable framerate, however using ffprobe it says that the max FPS is 25.47. So even if it was at the max FPS the whole video then I’d still only expect to see 984 pictures.

  Is there anyway to tell FFMpeg that my source video is only 25 fps ? Or am I missing something obvious ?
