SimplePie mRSS – Get at media:content URL?

Hi Guys,
I’m trying to pull in content from a mRSS feed. This is an example of the mRSS item:

<item>
	<title><![CDATA[Title Example]]></title>
	<link>https://example.com/</link>
	<guid>https://example.com/</guid>
	<description><![CDATA[movie.mov
	<br /><img src="https://example.com/image.jpg" />]]></description>

	<pubDate>Fri, 1 Dec 2009 00:42:21 +0000</pubDate>
	<enclosure url="https://example.com/movie.mov" type="video/quicktime" length="5319922"/>
	<media:content url="https://example.com/movie.mov" fileSize="5319922" type="video/quicktime" height="270" width="480"/>
	<media:thumbnail url="https://example.com/big_thumb.jpg" height="480" width="640"/>
	<media:thumbnail url="https://example.com/small_thumb.jpg" height="135" width="180"/>
	<media:credit role="client">Client</media:credit>
	<media:credit role="director">John Doe</media:credit>
	<media:credit role="agency" >Agency Example</media:credit>
	<media:credit role="production company">Example Production Company</media:credit>
	<media:credit role="award winner">Example Award</media:credit>
</item>

My question is, how do I get to the media:content url? I’m using this code, but it doesn’t work:

<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . '/feed.php');

// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed('https://www.example.com/feed/');
if (!is_wp_error( $rss ) ) : // Checks that the object is created correctly
    // Figure out how many total items there are, but limit it to 5.
    $maxitems = $rss->get_item_quantity(5); 

    // Build an array of all the items, starting with element 0 (first element).
    $rss_items = $rss->get_items(0, $maxitems);
endif;
?>

<?php if ($maxitems == 0) echo '<li>No items.</li>';
else
// Loop through each feed item and display each item as a hyperlink.
    foreach ( $rss_items as $item ) : ?>

	<a href="<?php echo $media->content->attributes()->url; ?>">Test</a>

<?php endforeach; ?>

I get this error:

Fatal error: Call to a member function attributes() on a non-object…

I know I’m doing doing this line wrong:
$media->content->attributes()->url

What is the correct syntax?

Thanks!
