IEnumDMO interface (mediaobj.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IEnumDMO interface provides methods for enumerating Microsoft DirectX Media Objects (DMOs). It is based on the OLE enumeration interfaces. For more information, see the IEnumXXXX topic in the Platform SDK.
To enumerate registered DMOs, call the DMOEnum function.
