WMP SDK Interfaces

  • Article

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This section documents the COM interfaces exposed by the Windows Media Player ActiveX control and the Windows Media Player Mobile ActiveX control.

The accessor methods of the IWMPCore or IWMPPlayer interface are used to retrieve specific interfaces. These interfaces, in turn, may have accessor methods for retrieving further interfaces. Calling QueryInterface on one of these interfaces is only necessary when you retrieve the base version of an interface and want to call a method on a later version of the same interface.

Note

All methods and events are fully supported in Windows Media Player 10 Mobile and later unless explicitly stated otherwise.

The Windows Media Player control exposes the following interfaces.
