Can't swipe over video, youtube or vimeo layer
We can either take control over the screen on the slides or not. When you put down a video, youtube or vimeo layer, it has actions on it, like pausing, playing the video either just touching the video, or it's controls, also at the controls there is the volume and other parts. To let you touch these, we have to let the video, youtube or vimeo layer to be in control, so every touching action happening over them is handled by them.
If you rather want swipe, and don't care about touching the video or just parts of it, then put down a transparent area layer over your video, and that can be swiped.
