Youtube Custom Player discontinued

In june 2011, YouTube removed support for the creation of new Custom Players, a specialized way of embedding playlists for playback on third party sites in a customizable interface. Existing players will continue to function. An example of a YouTube custom player is embedded in Cedrix Crespel’s music video webpage at Leslie’s Artgallery.

Similar functionality is available through creating embedded playlists, which can be accessed by visiting http://youtube.com/my_playlists, clicking Share, and then using the embed code given there.
