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
