IAMTimelineEffectable 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMTimelineEffectable interface provides methods for adding effects to a timeline object in DirectShow Editing Services (DES), and for manipulating the effects on an object. All objects that can have effects applied to them implement this interface; this includes sources, tracks, and compositions.

An object that implements this interface can have any number of effects. For each object, the render engine applies its effects in order of priority, starting with priority level 0.
