IAMTimelineObj Interface
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.
In addition to the methods inherited from IUnknown, the IAMTimelineObj interface exposes the following methods.
