IFilterGraph3 interface (strmif.h)

  • 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

The IFilterGraph3 interface extends the IFilterGraph2 interface, which contains methods for building filter graphs.

The Filter Graph Manager implements this interface. Applications can use it when building graphs, to take advantage of the additional methods it provides.
