, daha basit ve yürütülebilir yapılan Enjoy, belki bu size bazı yardımcı olur.

class VideoTile 
{ 
    public static function createMovieThumb($srcFile, $destFile = "test.jpg") 
    { 
     // Change the path according to your server. 
     $ffmpeg_path = 'D:\\ffmpeg\\bin\\'; 

     $output = array(); 

     $cmd = sprintf('%sffmpeg -i %s -an -ss 00:00:05 -r 1 -vframes 1 -y %s', 
      $ffmpeg_path, $srcFile, $destFile); 

     if (strtoupper(substr(PHP_OS, 0, 3) == 'WIN')) 
      $cmd = str_replace('/', DIRECTORY_SEPARATOR, $cmd); 
     else 
      $cmd = str_replace('\\', DIRECTORY_SEPARATOR, $cmd); 

     exec($cmd, $output, $retval); 

     if ($retval) 
      return false; 

     return $destFile; 
    } 
} 

Kullanım sorun nedir ...

$file = VideoTile::createMovieThumb("../video3.mp4");
