One way to convert a media RSS feed into a SMIL feed is to use the PHP XPath library.

<source lang="php">
<?php

$doc = new DOMDocument();

if( $doc->load('http://rss.server.com/mediarssfeed') ) // place your feed here
{
$xpath = new DOMXPath($doc);
$xpath->registerNamespace("media",
"http://search.yahoo.com/mrss/");
$nodes = $xpath->query('/rss/channel/item/media:content',$doc);
$ttlnode= $xpath->query('/rss/channel/ttl',$doc);

header( 'Content-Type: application/smil' );

echo "<smil><head>"
.'<layout><root-layout width="1280" height="720"/>'
.'</layout><meta http-equiv="Refresh" content="'
.$ttlnode->item(0)->textContent * 60
.'"/></head>'
."<body><seq repeatCount=\"indefinite\">\r\n" ;

foreach( $nodes as $node )
{
echo "\t<img src=\""
. $node->attributes->getNamedItem('url')
->textContent
. "\" dur=\""
. $node->attributes->getNamedItem('duration')
->textContent
. "\" />\r\n" ;
}

echo '</seq></body></smil>' ;
}

?>
