Why video_cover

video_cover stretches video element to cover it's parent, essentially emulating background-size: cover; for video elements.

Installation

Install video_cover by bower:

bower i video_cover -S

Usage

There are two ways to use video_cover: CommonJS module and jQuery plugin.

CommonJS

require(['video_cover'], function (video_cover) {
	video_cover.cover($('video'))
})

jQuery plugin

Other option is to just include video_cover library using a <script> tag and just call the video_cover function on any jquery object:

<script type="text/javascript" src="/assets/vendor/jquery/dist/jquery.js"></script>
<script type="text/javascript" src="/assets/vendor/video_cover/video_cover.js"></script>
<script type="text/javascript">
	$('video').video_cover()
</script>

Pure css approach

video_cover uses javascript to calculate optimal size and position of the video so that the container is covered. For some cases, javascript is not really required and the same effect can be achieved much more efficiently using pure css:

.parent-element-to-video {
    overflow: hidden;
}
video {
    height: 100%;
    width: 177.77777778vh; /* 100 * 16 / 9 */
    min-width: 100%;
    min-height: 56.25vw; /* 100 * 9 / 16 */
}

This approach works flawlessly if you know the aspect ratio of your video and you are trying to fill the whole screen(full background).
