/**
* A minimal YouTube player.
* <p>
* The URL/MRL must be in the following format:
*
* <pre>
* http://www.youtube.com/watch?v=000000
* </pre>
*
* The only thing that makes this different from a 'regular' media player application is the
* following piece of code:
*
* <pre>
* mediaPlayer.setPlaySubItems(true); // <--- This is very important for YouTube media
* </pre>
*
* Note that it is also possible to programmatically play the sub-item in response to events - this
* is slightly more complex but more flexible.
* <p>
* The YouTube web page format changes from time to time. This means that the lua scripts that vlc
* provides to parse the YouTube web pages when looking for the media to stream may not work. If you
* get errors, especially errors alluding to malformed urls, then you may need to update your vlc
* version to get newer lua scripts.
