IPropertySetter interface
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IPropertySetter interface sets properties on an effect or transition in DirectShow Editing Services (DES).
To use this interface, create an instance of a property setter object (CLSID_PropertySetter), and associate it with an effect or transition by calling the IAMTimelineObj::SetPropertySetter method. For more information, see Working with Effects and Transitions.
Usually an application needs to call only the IPropertySetter::ClearProps method to clear existing properties, and the IPropertySetter::AddProp method to add new properties. The other methods on this interface are called by other DES components.
Members
The IPropertySetter interface inherits from the IUnknown interface. IPropertySetter also has these types of members:
