Video Autoload, Play, and Load Next page…

I need help with the following:

I want to have a video intro play and preload. After the video plays, I want it to automatically load the next page, without the visitor having to click anywhere to advance to the next page. I just want the video to be seen, no header, or footer…. it plays, then loads the next page.

I also want this video to be displayed on all devices…. pc, laptop, tablet, and cell. I think the video will have to be an embedded youtube to be displayed on all devices. I did this years ago with Flash, but that’s now obsolete.

Your assistance and support is greatly appreciated.
