D3D12DDI_VIDEO_DECODE_BITSTREAM_ENCRYPTION_SCHEMES_DATA_0020 structure (d3d12umddi.h)

  • Article

Specifies information used to retrieve the bitstream encryption schemes supported for a decode profile.

Syntax

typedef struct D3D12DDI_VIDEO_DECODE_BITSTREAM_ENCRYPTION_SCHEMES_DATA_0020 {
  UINT NodeIndex;
  GUID DecodeProfile;
  UINT EncryptionSchemeCount;
  GUID *pEncryptionSchemes;
} D3D12DDI_VIDEO_DECODE_BITSTREAM_ENCRYPTION_SCHEMES_DATA_0020;

Members

NodeIndex

In multi-adapter operation, this indicates which physical adapter of the device this operation applies to.

DecodeProfile

The decode profile to retrieve bitstream encryption schemes for.

EncryptionSchemeCount

The number of schemes to retrieve. The runtime ensures this value matches the value returned from PFND3D12DDI_VIDEO_GETCAPS with D3D12DDI_CAPSTYPE_VIDEO set to D3D12DDICAPS_TYPE_VIDEO_DECODE_BITSTREAM_ENCRYPTION_SCHEME_COUNT.

pEncryptionSchemes

A pointer to a list of supported encryption schemes. The calling application allocates storage for the list before it calls the CheckFeatureSupport method.
