Registering Conversion Plug-ins
[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 It has been superseded by MediaPlayer.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.]
Third-party formats must be registered before Windows Media Player can instantiate and use the conversion plug-in. To register your file for conversion, you must register the file name extension associated with your format.
The list of registered file name extensions is maintained as a set of registry keys. For details about registering third-party formats, see File Name Extension Registry Settings. The following table lists the registry value settings to register a third-party format for conversion by using a conversion plug-in.
| Value | Setting |
|---|---|
| Runtime | 13 |
| Permissions | 8 (Permission for the library). |
| ConvertPluginCLSID | The class ID of the conversion plug-in, in registry format. |
