Slider/Carousel of Videos on Auto-Play (no video controls shown)

I've searched endlessly but can't find a solution...

I have mpeg videos (no video controls shown/autoplaying on loop) that I want to place in a slideshow. 

Is this possible?

No not really, you can't add videos to a gallery section.

You can try this approach to add video to Gallery Section (Tested with Gallery Grid. I haven't tested with Slideshow yet.)

First, add code to Website Tools > Code Injection > Footer

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('figure[class*="gallery-"] video').closest('figure').addClass('hide-image');
});
</script>

Next, add this code to Custom CSS

/* hide gallery section images */
 .hide-image [class*="-item-wrapper"] {
 display: none !important;
 }

Edit Gallery Section > edit each image > Enter this format to Caption  (code is a bit different because I added loop and autoplay)

<video width="100%" height="240" controls loop autoplay>
  <source src="https://www.w3schools.com/tags/movie.mp4" type="video/mp4">
</video>

You can repeat similar for other images, just replace .mp4 with new mp4 video url.

Result

Make sure Caption is enabled
