IKsPropertySet::Set method
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Set
method sets a property identified by a property set GUID and a property ID.

Note
Another interface by this name exists in the dsound.h header file. The two interfaces are not compatible. The IKsControl interface, documented in the DirectShow DDK, is now the recommended interface for passing property sets between WDM drivers and user mode components.
You must include Ks.h before Ksproxy.h.
