The content of the slide show shouldn’t matter.
If it is a slide show you should be able to add pictures and images to it. The only difference is that you would have different attributes for different media types.
Try suing the slide show you have found, and add video to it as if it was a picture. You’ll see how it works then.
For future reference first tell us what you have tried already and share some of the code you have already written so we can let you know or guide your to the right path.
