Same YouTube user channel feed import as above, but totally modified code using the WordPress function fetch_feed( $uri );
on Google+ Thomas Scholz (toscho) https://plus.google.com/115532307838378431827 asked me to sanitize the output and cache the result. Thank you!
fetch_feed caches for 12 hours by default, you might want to change this with wp_feed_cache_transient_lifetime (check yourself..)
fetch_feed also uses the WP sanitization class KSES (KSES Strips Evil Scripts) to validate the input (too high for me 
)
Here the code for fetching latest clips of a youtube channel, just title and image with link to the video on YT
Code:
<aside class="widget">
<h3 class="widget-title">Our Youtube Channel</h3>
<?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.youtube.com/feeds/videos.xml?channel_id=your CHANNEL ID' ); // use just the link of your feed ..
$maxitems = 0;
if ( ! is_wp_error( $rss ) ) : // Checks that the object is created correctly
// Figure out how many total items there are, but limit it to 3.
$maxitems = $rss->get_item_quantity( 3 );
// Build an array of all the items, starting with element 0 (first element).
$rss_items = $rss->get_items( 0, $maxitems );
endif;
?>
<ul>
<?php if ( $maxitems == 0 ) : ?>
<li><?php _e( 'No items', 'my-text-domain' ); ?></li>
<?php else : ?>
<?php // Loop through each feed item and display each item as a hyperlink. ?>
<?php foreach ( $rss_items as $item ) : ?>
<li>
<a href="<?php echo esc_url( $item->get_permalink() ); ?>" target="_blank" title="<?php echo esc_html( $item->get_title() ); ?>"> <?php echo esc_html( $item->get_title() ); ?></a>
<?php if ($enclosure = $item->get_enclosure()) // we get the thumbnail image link
{ $thumbnail = $enclosure->get_thumbnail();
$thumbnail = substr($thumbnail, 0,-13); // cut off 'hqdefault.jpg' and add new filename below
$thumb1 = $thumbnail."1.jpg"; // is a 120 wide image, Medium Quality Thumbnail (320x180 pixels) would be mqdefault.jpg
echo '<p><a href="' . esc_url( $item->get_permalink() ) . '" target="_blank" title="' . esc_html( $item->get_title() ) . '"> <img src="' . esc_url($thumb1) . '" width="120" height="90" alt="' . esc_html( $item->get_title() ) . '"/></a></p>';
} ?>
<p><small>Posted on <?php echo $item->get_date('j F Y | g:i a'); ?></small></p>
</li>
<?php endforeach; ?>
<?php endif; ?>
</ul>
</aside>
Try it somewhere in sidebar or footer, ask if you get a problem
