Installation and Usage

MediaElementPlayer: HTML5 <video> and <audio> player

A complete HTML/CSS audio/video player built on top MediaElement.js and jQuery. Many great HTML5 players have a completely separate Flash UI in fallback mode, but MediaElementPlayer.js uses the same HTML/CSS for all players.

Change Log

Changes available at Change Log

1. Add Script and Stylesheet

<script src="jquery.js"></script>
<script src="mediaelement-and-player.min.js"></script>
<link rel="stylesheet" href="mediaelementplayer.css" />

2. Add <video> or <audio> tags

If your users have JavaScript and/or Flash, the easiest route for all browsers and mobile devices is to use a single MP4 or MP3 file.

<video src="myvideo.mp4" width="320" height="240"></video>

<audio src="myaudio.mp3"></audio>

Optional: multiple codecs

This includes multiple codecs for various browsers (H.264 for IE9+, Safari, and Chrome, WebM for Firefox 4 and Opera, Ogg for Firefox 3).

<video width="320" height="240" poster="poster.jpg" controls="controls" preload="none">
	<source type="video/mp4" src="myvideo.mp4" />
	<source type="video/webm" src="myvideo.webm" />
	<source type="video/ogg" src="myvideo.ogv" />
</video>

Optional: Browsers with JavaScript disabled

In very rare cases, you might have a non-HTML5 browser with Flash turned on and JavaScript turned off. In that specific case, you can also include the Flash <object> code.

<video width="320" height="240" poster="poster.jpg" controls="controls" preload="none">
	<source type="video/mp4" src="myvideo.mp4" />
	<source type="video/webm" src="myvideo.webm" />
	<source type="video/ogg" src="myvideo.ogv" />
	<object width="320" height="240" type="application/x-shockwave-flash" data="flashmediaelement.swf">
		<param name="movie" value="flashmediaelement.swf" /> 
		<param name="flashvars" value="controls=true&amp;poster=myvideo.jpg&amp;file=myvideo.mp4" /> 		
		<img src="myvideo.jpg" width="320" height="240" title="No video playback capabilities" />
	</object>
</video>

3. Startup

Automatic start

You can avoid running any startup scripts by added class="mejs-player" to the <video> or <audio> tag. Options can be added using the data-mejsoptions attribute

<video src="myvideo.mp4" width="320" height="240" 
		class="mejs-player" 
		data-mejsoptions='{"alwaysShowControls": true}'></video>

Normal JavaScript

<script>
var player = new MediaElementPlayer('#player', {success: function(mediaElement, originalNode) {
	// do things
}});
</script>	

jQuery plugin

<script>
$('video').mediaelementplayer({success: function(mediaElement, originalNode) {
	// do things
}});
</script>

How it Works:

MediaElement.js: HTML5 <video> and <audio> shim

MediaElement.js is a set of custom Flash and Silverlight plugins that mimic the HTML5 MediaElement API for browsers that don't support HTML5 or don't support the media codecs you're using. Instead of using Flash as a fallback, Flash is used to make the browser seem HTML5 compliant and enable codecs like H.264 (via Flash) and even WMV (via Silverlight) on all browsers.

<script src="mediaelement.js"></script>
<video src="myvideo.mp4" width="320" height="240"></video>

<script>
var v = document.getElementsByTagName("video")[0];
new MediaElement(v, {success: function(media) {
	media.play();
}});
</script>

You can use this as a standalone library if you wish, or just stick with the full MediaElementPlayer.

Building MediaElement.js

When developing MediaElement, make changes to the files in the /src/ directory (not /build/) and test the changes with /test/test.html.

To compile the changes

1. Install node.js with npm https://nodejs.org/
2. At the command prompt type npm install which will download all the necessary tools
3. Type grunt to build MediaElement.js
4. To compile the Flash swf, you'll need to install Flex 4.6. See instructions in Gruntfile.js for details.
