Great! But you should also add:

$config->set('Filter.YouTube', true);

Actually, this filter will filter (possibly dangerous) embedded youtube video and convert the html to this:

And the second part of the filter will find the "youtube-embed" span class (that why you need to allow it :) ) and convert it to a "certified not dangerous" embedded object. :)
