Remarks

Windows Media Player determines the type and capabilities of a plug-in by checking the Windows registry, and will specify only properties that the plug-in supports.

Media and Playlist objects are sent to the plug-in as arrays of IUnknown pointers. The plug-in can call QueryInterface on these pointers to retrieve IWMPMedia or IWMPPlaylist interfaces.

Windows Media Player 10 Mobile: This method is not supported.

Requirements

Version: Windows Media Player 9 Series or later.
