Video Thumbnail Class Help

[ShoeLace1291]

I downloaded a class for generating video thumbnails, but the site I downloaded it from has no support for it and the example provided is worthless.  Maybe I just don't understand it or maybe it doesn't even work(which I doubt).  I have my own "video" class that pulls the videos from the database, there's the example.php file, and the thumbnail class(downloaded) called snapshot.php.  Basically, what I need to know is how to output the file.  Here is my script:

 

My video class:

<?php

class video {

function latest(){

	ob_start();

		$query = mysql_query("SELECT * FROM videos ORDER BY videoID DESC LIMIT 5") or die("Video Error1: ".mysql_error());
		if(mysql_num_rows($query) == 0){
			echo "<h2>There are no videos to display at this time.</h2>";
		} else {
		while($video=mysql_fetch_array($query)){
				$videoID=$video["videoID"];
				$title=$video["title"];
				$author=$video["authorID"];
				$description=$video["description"];
				$metaTags=$video["metaTags"];
				$dateposted=$video["dateposted"];

					if(strlen($title) > 15){
						$title = substr($title, 0, 14)."...";
					}

					$cfg['snapshot'] = array(
							'program' => '/usr/bin/mplayer',
							'outdir' => '/tmp',
							'progressive' => False,
							'baseline' => True,
							'optimize' => 100,
							'smooth' => 0,
							'quality' => 90,
							'frames' => 5,
							'delete' => False
);

					(object) $img = new Snapshot( $cfg['snapshot'] );
					$img->getOutfile();

				$template = new template;					
				$variables = array(
								   'VIDEO_ID' => $videoID,
								   'TITLE' => $title,
								   'DESCRIPTION' => $description,
								   'SNAPSHOT' => $img->getOutfile()
								   );
				$file = "template/video_links.tpl";
				echo $template->passvars($variables, $file);

			}
		}

	$ret=ob_get_contents();
	ob_end_clean();
	return $ret;

}

 

The script of the example:

<?php

// @example 

// Define class settings
$cfg['snapshot'] = array(
	'program' => '/usr/bin/mplayer',
	'outdir' => '/tmp',
	'progressive' => False,
	'baseline' => True,
	'optimize' => 100,
	'smooth' => 0,
	'quality' => 90,
	'frames' => 5,
	'delete' => False
);

// Path to the input file
(string) $file = "videos/Material Hazard Demo.wmv";

// Load the Snapshot class
include_once('classes/snapshot.php');

try {

// Create the $img object
(object) $img = new Snapshot( $cfg['snapshot'] );

// Extract a jpeg image from defined video file
if ( $img->extract( $file ) ) {
	if ( is_file($img->getOutfile()) ) {
		// If you have set the parameter delete to Fale, you have
		// to delete the extracted file manually with the remove() method.
		echo $file." was successfuly extracted to <a href=\"file://".$img->getOutfile()."\">".$img->getOutfile()."</a><br/>\n";
	} else {
		echo "Sorry, but I can't find any output file!";
	}
} else {
	echo "Can't extract an image from the movie [".$file."]!";
}

// You also can stream the image (send image header)
// if you set the second parameter to True
//if ( !$img->extract( $file, True ) ) {
//	echo "Can't extract ".$file;
//}

// You can remove the outfile manullay if $delete is False
//if ( $cfg['snapshot']['delete'] === False ) {
//	if ( !$img->remove($img->getOutfile()) )
//		die( "Can't delete the output file [".$img->getOutfile()."]!" );
//}

} catch ( Exception $error ) {
echo "Error: ".$error->getMessage()."; on line ".$error->getLine()." in ".$error->getFile()."\n";
}

?>

 

Note that I pass variables to a template file with $template->passvars($variable, $file) with SNAPSHOT as the variable for the snapshot image.  This has been irritating me for quite some time now, so any help provided would be much appreciated.
