WMT_PROP_DATATYPE enumeration (wmcodecdsp.h)

Defines the data types used for the codec and DSP properties that are accessed by using the methods of the IWMCodecProps interface.

Syntax

typedef enum WMT_PROP_DATATYPE {
  WMT_PROP_TYPE_DWORD = 0,
  WMT_PROP_TYPE_STRING = 1,
  WMT_PROP_TYPE_BINARY = 2,
  WMT_PROP_TYPE_BOOL = 3,
  WMT_PROP_TYPE_QWORD = 4,
  WMT_PROP_TYPE_WORD = 5,
  WMT_PROP_TYPE_GUID = 6
} ;

Constants

WMT_PROP_TYPE_DWORD Value: 0 Specifies a double-word value.
WMT_PROP_TYPE_STRING Value: 1 Specifies a string value.
WMT_PROP_TYPE_BINARY Value: 2 Specifies a binary value.
WMT_PROP_TYPE_BOOL Value: 3 Specifies a Boolean value.
WMT_PROP_TYPE_QWORD Value: 4 Specifies a quadruple-word value.
WMT_PROP_TYPE_WORD Value: 5 Specifies a word value.
WMT_PROP_TYPE_GUID Value: 6 Specifies a GUID value.
