Last month or so I had been working on a Youtube Media Connector for Sitecore Media Framework. I wrote six blog articles to explain how Sitecore Media Framework works and how I built this connector. I never intended to create a fully functional application. My intention was create a Youtube Media Connector that the developers can take and extend for their need. At the same time, I wanted to make sure that the connector works to the extent, so that, it can be used by the developers in Sitecore application, where they want to add Youtube videos. Being said that, I will add new features to the connector as time permits, but you are more than welcome to extend it, change it for your purpose. Here are different links for the connector.
