title: PHP exec() on windows not working
body: <p>Hey, I'm trying to execute a program on windows through PHP, the command is posted below.  This doesn't seem to be running through the script at all, even though it works when the command is manually entered into the command prompt.</p>
  
  <pre><code>exec('C:\\ffmpeg -i ' . $movedfile . ' -acodec aac -ab 128k -vcodec libx264 -fpre C:\\ffmpeg\\share\\ffmpeg\\libx264-hq.ffpreset -crf 22 -threads 0 -wpredp 0' . $convertedfile);
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Thanks!</p>
