YouTube and Vimeo APIs

YouTube and Vimeo have nice APIs to allow JavaScript developers to control the playback of embedded content (oh, and YouTube has a new design). They’ve also updated the APIs to use the newer <iframe> embed style instead requiring <object><embed> flash tags. But as powerful as those APIs are, they are not consistent with each other and neither one conforms to HTML5 <video> properties or events so you can’t leverage your existing skills or code.

MediaElement.js HTML5 Wrapper

To make the YouTube and Vimeo APIs easier to use, I wrapped the MediaElement.js shim structure around their proprietary APIs to make them feel like HTML5. So for a YouTube video, you can use this <video> markup

<video id="youtube1" width="640" height="360">
	<source src="http://www.youtube.com/watch?v=nOEw9iiopwI" type="video/youtube" >
</video>

Then to build a full-fledged player that is CSS skinnable on top of YouTube Chromeless , you can simply call the MediaElementPlayer like this:

jQuery(document).ready(function($) {
	$('#youtube1').mediaelementplayer();
});

Demo

Or you can skip MediaElementPlayer’s controls and build your own player using just the MediaElement wrapper which does not require jQuery (MediaElement is the wrapper which shims HTML5 support into old browsers, MediaElementPlayer is the full-fledged jQuery-based control bar built on top of MediaElement).

new MediaElement('youtube#', {
	success: function(media, domNode) {
		// add HTML5 events to the YouTube API media object
		media.addEventListener('play', function() {
			console.log('yeah, it is playing!');
		}, false);

		media.addEventListener('timeupdate', function() {
// access HTML5-like properties
			console.log('current: ' + media.currentTime);
		}, false);

		// add click events to control player
		myMuteButton.addEventListener('click', function() {
			// HTML5 has a "muted" setter, but we have to use a function here
			media.setMuted(true);
		}, false);
	}
});

Once the success event fires, the media object is a JavaScript wrapper that mimics the HTML5 Media API, but under the hood is really a wrapper around YouTube’s API. Nice right?

Gotchas

There are a few things you should look out for if you want to try it:

• This code is now in the official 2.4.0 release of MediaElement.js, but it should be considered experimental. I’d like to pull it out of the core and make it a plugin, but this will require some re-architecting.
• The Vimeo API wrapper is not finished yet. It will simply display the default Vimeo controls. (Also, unlike YouTube’s chromeless option, only Vimeo Pro users can totally remove controls)
• Some browsers (Chrome, IE) don’t allow HTML to be placed over an <iframe> with Flash inside which makes MediaElementPlayer’s controls not work, so I’m using the pure Flash version of YouTube for desktop browsers
• Fullscreen: JavaScript can’t initiate Flash’s true fullscreen, and Firefox still has terrible Flash support (if you try to adjust the size of a Flash movie’s surrounding DOM nodes, Firefox reloads it!)
