Youtube support in release 3 (FIXED)

When I embed a Youtube video as HTML code and add the tag <iframe> to System > Settings > Security > Allowed HTML Tags the video plays fine.

But when I use the youtube video ID in content element Youtube, which is new in Contao 3, the youtube video does not play. Firefox reports no video with supported format and file type found. Other browsers have similar behaviour.

This is what the page source looks like:

<div class="ce_youtube block">
<h1>TESTVIDEO</h1>

<video width="640px" height="480px" controls>
<source type="video/x-youtube" src="http://www.youtube.com/watch?v=HzFHmbl8ye0">
</video>

</div>

Does anyone have similar experience?

I tried it and it didn't work for me either!
So I tried the contao online demo. Guess what? That didn't work either :lol:

Oh well. at least there are other ways to do it by embedding the <iframe> code from youtube.

Thx - I wondered already what I did wrong.

Fixed: Backend > themes > page layout > default page > activate moo_media-elements

The youtube video showed once the moo_media-element was active for the page.
