Forcing Featured Video Plus to display Lyte YouTubes

A couple of days ago a WP YouTube Lyte user asked me if Featured Video Plus and WP YouTube Lyte were compatible. It took me a day to find the answer (I first said “no”), but Featured Video Plus actually has a filter (get_the_post_video_filter) that allows one to override the code used to display the featured video. And after a bit of trial and error this is what I came up with;

add_filter('get_the_post_video_filter','lyte_featured_video');
function lyte_featured_video($in) {
	$post_id = ( null === $post_id ) ? get_the_ID() : $post_id;
	$meta = get_post_meta( $post_id, '_fvp_video', true );
  	if (($meta["provider"]==="youtube") && (function_exists('lyte_parse'))) {
		return lyte_parse($meta["full"]);
	}
 	return $in;
}

Some extra checks ($post_id should not be empty, $meta should not be empty) would make this more reliable, but that’s something you should be able to add, no?
