How to extract "description" tag from a video file info in PHP?

Could somebody help me with PHP code to read the description of a .mov or .mp4 video file?

The getID3开发者_高级运维() does not get the Description information (screenshot attached to show what I want)

Use the PHP Function: http://www.php.net/manual/de/book.id3.php

$tag = id3_get_tag( "path/to/example.mp3" );
print_r($tag);

Or use this: http://sourceforge.net/projects/getid3/
