Windows Driver Kit DDI reference (ne-iddcx-iddcx_metadata2_valid_flags)

Description

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

Constants

`IDDCX_METADATA2_VALID_FLAGS_NONE: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: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.

`IDDCX_METADATA2_VALID_FLAGS_HDR10METADATA:0x2`

When set, IDDCX_METADATA2::Hdr10FrameMetaData contains valid data.

Remarks

For more information about HDR support, see IddCx version 1.10 updates.
