    data-cookieconsent="marketing"
    class=" cookieconsent-optin-marketing"

    {% if query is not empty %}
      ?{{ query | url_encode }}
    {% endif %}

    {% if fragment is not empty %}

    {% endif %}"
  {% endif %}

</iframe>
<div class="cookieconsent-optout-marketing">
   {{ 'Please <a href="javascript:Cookiebot.renew()">accept marketing-cookies</a> to watch this video'|t }}
