IAMTimelineObj 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMTimelineObj interface provides methods for manipulating timeline objects in DirectShow Editing Services (DES). All timeline objects implement this method, including source, effect, transition, track, group, and composition objects. Create a timeline object by calling the IAMTimeline::CreateEmptyNode method.

Members

The IAMTimelineObj interface inherits from the IUnknown interface. IAMTimelineObj also has these types of members:
