  I’m having issue with converting mov files from iPhone 4.

  Running this command :

  My ffmpeg gives me errors like this :

  It’s only happening for mov files. There are couple of tricky places it looks like it’s trying to take screenshot from a video.

  Maybe anyone witnessed anything similar and can give me a tip ?

• PHP ffmpeg exec returns null

  19 mars 2012, par benedict_w

  I'm trying to run ffmpeg through a PHP exec call, I've been debugging for a while and looked at lot of responses on here, but still not found any answers...

  My simplified call is :

  $cmd = 'ffmpeg 2>&1';
  
  
  
  exec(escapeshellcmd($cmd), $stdout, $stderr);
  
  
  
  var_dump($stderr);
  
  var_dump($stdout);
  
  var_dump($cmd);
  
  exit;

  My output is $stderr = int(1) and $stdout = array(0)

  Also I tried shell_exec($cmd) which returns NULL.

  cmd.exe has permissions set for the IUSR account - e.g. I can run $cmd = 'dir' and see a directory listing output.

  PHP is not running in safe mode.

  The ffmpeg.exe is in the same directory as my php file, but I have the same response giving an absolute path to the ffmpeg.exe file in $cmd.

  ffmpeg is executing fine from the command line.

  I'm running Windows XP, IIS and PHP 5.3.

  EDIT :

  If I run 'ffmpeg -h' I get the help commands, which must indicated that ffmpeg is recognised

  I've increased the PHP memory limit to 1024 - no luck.
