const DMO_PARTIAL_MEDIATYPE* pInTypes,
DWORD cOutTypes,
const DMO_PARTIAL_MEDIATYPE* pOutTypes,
IEnumDMO** ppEnum
);
Parameters
- guidCategory
One of the DMO GUIDs. It specifies which category of DMO to search. Use GUID_NULL to search every category.
- dwFlags
Bitwise combination of zero or more flags from the DMO_ENUM_FLAGS enumeration.
- cInTypes
Number of input media types to use in the search criteria. Use zero to match any input type.
- pInTypes
Pointer to an array of DMO_PARTIAL_MEDIATYPE structures that contain the input media types. Specify the size of the array in the cInTypes parameter.
- cOutTypes
Number of output media types to use in the search criteria. Use zero to match any output type.
- pOutTypes
Pointer to an array of DMO_PARTIAL_MEDIATYPE structures that contain the output media types. Specify the size of the array in the cOutTypes parameter.
- ppEnum
Address of a variable to receive the IEnumDMO interface of the enumerator.
Return Value
