Constructing a Timeline
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
[This API is not supported and may be altered or unavailable in the future.]
This article describes how to construct a timeline in DirectShow Editing Services (DES). It presents an example console application that creates a timeline and renders it. The timeline is minimal, consisting of a single video group with one source clip, but it demonstrates most of the concepts needed to create more complex timelines.
