HTML Video Player for Cell Phones / Iphones

I'm trying to set up a QR Code that when scans will be taken to my HTML website with a full screen video auto playing, but I don't want to use youtube or vimeo because of the water mark. Where would I get the code to make this happen? Also what HTML5 video player will do this? It has to be full screen not a video player on the page.

You don't need a player; HTML5 allows embedding video files directly:

Just like Chris said, HTML5 supports Audio and Video now.

All you need to do is:
<audio src="path/to/video.mp4"/> Of course, you can add more attributes as you go along.
