IBasicVideo2 interface (control.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IBasicVideo2 interface extends the IBasicVideo interface. The Video Renderer filter and Video Mixing Renderer filters implement this interface, but the interface is exposed to applications through the Filter Graph Manager. Applications should always retrieve this interface from the Filter Graph Manager.
