Need help reading dimensions of an mp4 video using ffmpeg

PROBLEM : I need dimensions of my mp4 video -- I am getting the size but not the width and height. Why?

HERE IS THE OUTPUT

Opening fileinfo database worked.
vid: Library/Oct_2011_Bubbie.mp4video/mp4; charset=binary
Mine: video/mp4
array(7) {
 ["codec"]=> NULL
 ["width"]=> NULL
 ["height"]=> NULL
 ["hours"]=> NULL
 ["mins"]=> NULL
 ["secs"]=> NULL
 ["ms"]=> NULL
} Codec:
Dimension: x
Duration: ::.
Size: 5.86M

HERE IS THE CODE:

if (!$finfo) {
    echo "Opening fileinfo database failed";
    exit();
}
echo "Opening fileinfo database worked.<br />";
$vid = 'Library/Oct_2011_Bubbie.mp4'; //Replace here!
//$vid = 'UpDataFiles/94/IMG_2590.JPG';

    $mime_type = finfo_file($finfo, $vid); // check mime type
     echo "<br /> Mine: ".$mime_type. '<br/>';
