this code far:

one quick way replace picture background video, place video on top of picture, , make cover parent's area using object-fit. requires minor html , css changes:

html:

<div id="bg">      <video autoplay loop>           <source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4"/>           <source src="http://www.w3schools.com/html/mov_bbb.ogg" type="video/ogg"/>      </video> </div>

css:

#hero video {   width:100%;   height:100%;   object-fit:cover; /* resize video cover parent, background-size:cover */ }  #hero #bg {   /* styles #bg remain same, you'd need add */   /* 1 more, video overflows #hero hidden: */   overflow:hidden;  }

you can see example working on jsfiddle: http://jsfiddle.net/zxqz7oe0/1/

one issue of solution object-fit not supported yet: chrome, firefox, , android ok, may face problem on firefox , mobile. , ie doesn't support @ all. (you can see browser support here.)

you use simple method, , have javascript fallback solution browsers not support object-fit. knowing video size, easy calculate width/height needed @ each moment when window loaded/resized.
