FFMPEG running in Command Line but not PHP

Question

I am using ffmpeg build for windows to make video thumbnails . The command works well in command line but not from PHP exec method. am using PHP 5.2.11

Here is the command.

"E:/Documents and Settings/x/WINDOWS/ffmpeg" -itsoffset -4 -v "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/videogal/c08c3d20eeb9083ed033577bd154cba6.flv" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/gallery/8ff43b72b932d2a34e7a6733672ad4d6.jpg" 2>&1

Can somebody help. I checked the permissions they seem fine. GD is installed.

The error msg is 'E:/Documents' is not recognized as an internal or external command, operable program or batch file

Am using forward slashes in my paths except when escaping double quotes

The PHP function

function ExtractThumb($in, $out)
{$path=dbconf::FFMPEG_PATH;
    $thumb_stdout;
    $errors;
    $retval = 0;
 echo $in;
    // Delete the file if it already exists
    if (file_exists($out)) { unlink($out); }

    // Use ffmpeg to generate a thumbnail from the movie
    $cmd = "$path -itsoffset -4 -i $in -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 $out 2>&1";
   echo $cmd;

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

    // Queue up the error for processing
    if ($retval != 0) { $errors[] = "FFMPEG thumbnail generation failed"; }

    if (!empty($thumb_stdout))
    {
        foreach ($thumb_stdout as $line)
        {
            echo $line . "\n";
        }
    }

    if (!empty($errors))
    {
        foreach ($errors as $error)
        {
            echo $error . "\n";
        }
    }
}

funny enough if I run without the $in and $out absolute path this is what I get

Answer 1

exec("\"E:\\Documents and Settings\\x\\WINDOWS\\ffmpeg\" -i <inputfile> <options> <outfile>");

Here's one of mine I've used in the past (granted I'm on a LAMP stack):

$cmd = "/usr/bin/ffmpeg -i ".$in." -y -an -sameq -vframes 1 -s 100x56 -ss 3 -t 0.001 ".$out;

You need to escape your command properly:

exec(escapeshellcmd($cmd), $thumb_stdout, $retval);

Also do you have PHP safe mode on? You should check that $in is a real file before trying to encode too.
