IDirectDrawVideo::SetDefault method (amvideo.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetDefault method makes the current property settings the global default.
Syntax
HRESULT SetDefault();
Return value

Remarks

Call this method to make properties set on this instance of IDirectDrawVideo the global default of all DirectShow instances of this interface.
