Yes. I am aware of that. My friend has a plus account. And with the embed code I got from vimeo it was possible to achieve the fullscreen on desktop, but not on mobile.

I am afraid if I download the video the filesize would be probably to big to display as background-video, that’s why I want to use the embed-option. + I read somewhere else that it’s always better to use the embed-option …
A workaround which “breaks” the origin ratio of the video for different viewports would be awesome.
