YouTube RSS

This add-on makes it very easy to get access to YouTube's custom RSS tags known as Yahoo Media RSS. Data includes the player, thumbnail, title, author and alternate categories. Also there is a 'is_youtube' available in every item, so you can base format behavior on that. There is a screencast available that shows how a simelar Add-on was created: Creating the Digg SimplePie Add-on.

1. Create a new file called simplepie_youtube.inc and place it in the same directory as your simplepie.inc file.
2. On the SimplePie-enabled page you want to use this extension on, make sure you include it in the same way that you include simplepie.inc.
