IDxtKey interface

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note

[Deprecated. This API may be removed from future releases of Windows.]

 

The IDxtKey interface sets properties on the Key transition.

This interface is used internally by DirectShow Editing Services (DES) when it renders the Key transition. DES applications do not need to use this interface. To set the properties on a transition in DES, use the IPropertySetter interface.

Members

The IDxtKey interface inherits from IDXEffect. IDxtKey also has these types of members:
