AddType video/ogg .ogv
AddType video/webm .webm

HTML

<div class="fullscreen-bg">
    <video loop muted autoplay poster="img/videoframe.jpg" class="fullscreen-bg__video">
        <source src="video/big_buck_bunny.webm" type="video/webm">
        <source src="video/big_buck_bunny.mp4" type="video/mp4">

  .fullscreen-bg__video {
    display: none;
  }
}

Beispiel 2 - jquery.background-video

jQuery Background Video

Instantly improve your HTML5 background videos with a single line of jQuery.

Built by the folks over at BG Stock - Premium HTML5 Background Videos. What does the plugin do?

The plugin allows you to enhance your background videos in a few ways

   Allows you to fade in your video when it starts playing (to avoid a sudden jump)
   Emulates background-size: cover; / object-fit: cover;
   Destroys the video and prevents it downloading on iOS devices (because they can't do background video)
   Optionally auto-pause video after X seconds (easier on your users' power consumption)
   Optionally add and position a pause/play button

Example: http://codepen.io/GusRuss89/pen/bVwNrE Installation

With bower

bower install jquery-background-video

With npm

npm install --save jquery-background-video

With git

git clone https://github.com/BGStock/jquery-background-video

Or just download the zip How do I use it? 1. Include the latest version of jQuery. E.g.

<script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>

2. Include jquery.background-video.js

<script src="path/to/jquery.background-video.js"></script>

3. Add a <video> as the first child of the element that you want it to be the background for

<div class="element-with-video-bg jquery-background-video-wrapper">
	<video class="my-background-video jquery-background-video" loop autoplay muted poster="path/to/your/poster.jpg">
		<source src="path/to/video.mp4" type="video/mp4">
		<source src="path/to/video.webm" type="video/webm">
		<source src="path/to/video.ogv" type="video/ogg">
	</video>
</div>

Note: the class names jquery-background-video and jquery-background-video-wrapper are only used in the CSS, just remember to update them there if you want to change them. The class name my-background-video is for demo purposes, this can be whatever you like.

If you're using the fade-in option you should also set the poster image as a background-image for your wrapper element.

.element-with-video-bg {
	background-image: url(path/to/your/poster.jpg);
}

It's important to use background-image instead of the shorthand background because the plugin CSS sets background-position, background-repeat and background-size, which would be overwritten by the shorthand background. 4. Call the plugin on the video element

In your main JavaScript file

$(document).ready(function(){
	$('.my-background-video').bgVideo();
});

OR

With a data attribute on the video tag

<video data-bgvideo="true" [other video params]>

5. (Recommended) include or copy/paste the CSS into your project

<link rel="stylesheet" type="text/css" href="path/to/jquery.background-video.css">

Options Default options

$('.my-background-video').bgVideo({
	fullScreen: false, // Sets the video to be fixed to the full window - your <video> and it's container should be direct descendents of the <body> tag
	fadeIn: 500, // Milliseconds to fade video in/out (0 for no fade)
	pauseAfter: 120, // Seconds to play before pausing (0 for forever)
	fadeOnPause: false, // For all (including manual) pauses
	fadeOnEnd: true, // When we've reached the pauseAfter time
	showPausePlay: true, // Show pause/play button
	pausePlayXPos: 'right', // left|right|center
	pausePlayYPos: 'top', // top|bottom|center
	pausePlayXOffset: '15px', // pixels or percent from side - ignored if positioned center
	pausePlayYOffset: '15px' // pixels or percent from top/bottom - ignored if positioned center
});

All options can alternatively be specified in data attributes on your video tag with a bgvideo prefix. Just change camel casing to hyphens and lower case. E.g. fadeIn becomes data-bgvideo-fade-in.

<video data-bgvideo="true" data-bgvideo-fade-in="2000" [other video params]>

Overriding default options

Example

$.fn.bgVideo.defaults.fadeIn = 5000;
$.fn.bgVideo.defaults.showPausePlay = false;
