[TYPO3-english] Get Youtube Thumbnail via Typoscript

[Chris Sy]

Hi

How to render a youtube thumbnail image file in typo 7.6.9?

If I use 

{namespace vhs=FluidTYPO3\Vhs\ViewHelpers}
<vhs:variable.set name="pageUid" value="{data.pid}" />
<vhs:resource.record.fal table="pages" uid="{pageUid}" as="pageMedia" field="media" >
  <f:for each="{pageMedia}" as="media" iteration="mediaIteration">
    <f:image src="{media.uid}" class="thumbnail" treatIdAsReference="1" />
  </f:for>
</vhs:resource.record.fal>

everything works as expected.

I can "upload" a youtube video in page ressources via youtube link and with the snippet above it shows the youtube thumbnail image on my page .

If I want to "translate" this snippet to typoscript, it doesn't work:

lib.youtubethumb = IMAGE
lib.youtubethumb {
  file {
    import.data = {field: muid}
    treatIdAsReference = 1
    import.listNum = 0
  }
}

I call this snippet via:
<f:cObject typoscriptObjectPath="lib.youtubethumb" data="{muid: media.uid}" />
inside the for loop.

The snippet work for all pictures jpeg jpg png gif, but not for media with .youtube extension.

I also tried:

lib.youtubethumb = IMAGE
lib.youtubethumb {
  file {
    import.data = {field: muid}
    treatIdAsReference = 1
    import.listNum = 0
    ext = "youtube"
  }
}

It doesn't work either.

What am I doing wrong? 

My final goal is to put a play icon onto the youtube thumbnail. I want to use GIFBUILDER, but I failed at a very early point. Thats why the snippet is sooo basic :).

Thanks, Cheers
