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
<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>
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;
