/*
HTML5 Video using Shortcode within WP

This feature is meant to make HTML5 Video easy to use.
to post a video, you simply have to use the shortcode:

[video src="filename" width="640px" height="340px" poster="imagename.jpg"]

Don't add a file extention as this will be added depending on what
browser you are using. Remember you need two file formats for it to
work consistently across all browsers:

filename.mp4 (used for Safari, Chrome, Flash Fallback)
filename.ogv (used for Firefox)

Be sure to make sure your directories are correct.
Defaults are in your uploads folder in wp-contents, 
but you can change it if you use a CDN or another 
hosting service.

This code was built upon a plugin created by Rob McGuire (http://robmcguire.net/)
