Add a background video to your website…
The full source can be downloaded from the master branch on GitHub (as a zip or gz) or installed via bower (bower install background-video).
Add the script to your homepage after jquery <script src="js/libs/jquery.backgroundvideo.min.js"></script>
And launch the plugin :
<script>
  $(document).ready(function() {
    var videobackground = new $.backgroundVideo($('body'), {
      "align": "centerXY",
      "width": 1280,
      "height": 720,
      "path": "media/",
      "filename": "cloud",
      "types": ["mp4","ogg","webm"],
      "preload": true,
      "autoplay": true,
      "loop": true
    });
  });
</script>
