You can use:

$subject = '<iframe width=\"425\" height=\"349\" src=\"http://www.youtube.com/embed/YRUG-Pu7RzE\" frameborder=\"0\" allowfullscreen></iframe>';
$pattern = '!http://(?:www.)?youtube.com/embed/([^"']+)!i';
$result = preg_match($pattern, $subject, $subpattern); 

$subpattern will contain:

Array ( [0] => http://www.youtube.com/embed/YRUG-Pu7RzE [1] => YRUG-Pu7RzE )
