IDDCX_METADATA2_VALID_FLAGS enumeration (iddcx.h)

  • Article

A IDDCX_METADATA2_VALID_FLAGS enumeration value indicates which fields in an IDDCX_METADATA2 structure have valid content.

Syntax

typedef enum IDDCX_METADATA2_VALID_FLAGS {
  IDDCX_METADATA2_VALID_FLAGS_NONE = 0,
  IDDCX_METADATA2_VALID_FLAGS_SYSTEMBUFFERINFO = 0x1,
  IDDCX_METADATA2_VALID_FLAGS_HDR10METADATA = 0x2
} ;

Constants

 
IDDCX_METADATA2_VALID_FLAGS_NONE
Value: 0
Indicates that none of the optional fields in IDDCX_METADATA2 contain valid data and they should not be referenced.
IDDCX_METADATA2_VALID_FLAGS_SYSTEMBUFFERINFO
Value: 0x1
When set, IDDCX_METADATA2::SystemBufferInfo contains valid data. The OS sets this flag in response to a driver setting IDARG_IN_RELEASEANDACQUIREBUFFER2::AcquireSystemMemoryBuffer to TRUE.

Value: 0x2
When set, IDDCX_METADATA2::Hdr10FrameMetaData contains valid data.
