DMO_ENUM_FLAGS enumeration (dmoreg.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 DMO_ENUM_FLAGS enumeration defines flags that specify search criteria when enumerating Microsoft DirectX Media Objects (DMOs).
Syntax
typedef enum DMO_ENUM_FLAGS {
DMO_ENUMF_INCLUDE_KEYED = 0x00000001
} ;
Constants
DMO_ENUMF_INCLUDE_KEYEDValue: 0x00000001 The enumeration should include DMOs whose use is restricted by a software key. If this flag is absent, keyed DMOs are omitted from the enumeration. |
Remarks
A software key enables the developer of a DMO to control who uses the DMO. If a DMO has a software key, applications must unlock the DMO to use it. The method for unlocking the DMO depends on the implementation. Consult the documentation for the particular DMO.
