i want to use a "no-cookie"-vimeo-video (iFrame-Code) in a Slider. It dont work!

hello.

i have a vimeo video and want to put in into a slider.

In the standard enfold-Slider they say, i can only put a normal link of the video in the slider. But then the user get a cookie. And i dont want this of course the DSGVO law. The Borlabs Cookie Plug in dont support Cookie-Blocking of Videos in a slider.

Vimeo say, i have to put the following iFrame Code into a Slider, then it works without a Cookie.
I installed the plug in Smart Slider. Then i put this iFrame Code into the slider:

<iframe src=”https://player.vimeo.com/video/509678610?background=1&dnt=1&#8243; width=”100%” height=”900″ frameborder=”0″ allow=”autoplay; fullscreen” allowfullscreen></iframe>

here is a link:

But it also doesnt work! When i look in the browser chrome tools there i saw a changed iFrame Code:
<iframe src=”https://player.vimeo.com/video/509678610?background=1amp;&dnt=1″ width=”100%” height=”900″ frameborder=”0″ allow=”autoplay; fullscreen” allowfullscreen></iframe>

the smart slider support says: something on the enfold theme or another plug in is changing the iFrame code, so it doesnt work like i want it.

what the hell…..
i only want to put a video into a slider without using a cookie.
help needed…..
