Testing html5 <video> element for background images

Doesn't play, falls back to poster image. No loading delay.
Plays smoothly, first time loading takes awhile, but fast afterwards

Does not play. 

I believe the video loads, but iOS disables autoplay without user interaction first (ie a tap)

For best compatablity going forwards use this setup

<video autoplay loop poster="poster.jpg" style="width: 100%;">
  <source src="Penguins_of_Madagascar.m4v" type="video/mp4">
   <source src="Penguins_of_Madagascar.webm" type="video/webm">
   <source src="Penguins_of_Madagascar.ogv" type="video/ogg">
   <source src="Penguins_of_Madagascar.mp4">
  Your browser doesn't support the video tag and is lame


iPad and DMP do not support HTML5 Video

However there is a workaround. By using a custom overlap layout in ArthurMP, a video can be put in the background, and the html overlayed overtop.
