Create Thumbnail from video

[subzero]

function makeThumbnails($dir){
   if (is_dir($dir))
   {
      if ($dh = opendir($dir))
      {
         while (($file = readdir($dh)) !== false)         
         {
            if($file != "." && $file != ".." && eregi(".mp4", $file))
            {
               $file='/'.$file;
               $command = "ffmpeg -i " . $dir . $file . " -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 -ss 00:00:10 " .  $dir . str_replace(".mp4", ".jpg", $file) ;
               return exec("$command");
            }//end if
         }//end while
      closedir($dh);
      }//end if handle $dh
   }//end if dir
   return TRUE;
}//end function makeThumnails()

This of course will make a 320x240 jpg from a mp4 file from the frame 10sec into the movie
ffmpeg is quite powerful it will use pretty much any video container/codec, just change those parts.

(oh yeah the function returns a boolean and the while loop means it keeps doing it while there is another
movie in the dir to make a thumbnail for! I guess that's pretty obvious. If you take the "command" out and
run it in a terminal with the variables $dir and $file changed to indicate the movie, etc. it will just make one!)
