D3D11_VIDEO_CONTENT_PROTECTION_CAPS structure (d3d11.h)

Describes the content-protection capabilities of a graphics driver.

Syntax

typedef struct D3D11_VIDEO_CONTENT_PROTECTION_CAPS {
  UINT      Caps;
  UINT      KeyExchangeTypeCount;
  UINT      BlockAlignmentSize;
  ULONGLONG ProtectedMemorySize;
} D3D11_VIDEO_CONTENT_PROTECTION_CAPS;

Members

Caps

A bitwise OR of zero or more flags from the D3D11_CONTENT_PROTECTION_CAPS enumeration.

KeyExchangeTypeCount

The number of cryptographic key-exchange types that are supported by the driver. To get the list of key-exchange types, call the ID3D11VideoDevice::CheckCryptoKeyExchange method.

BlockAlignmentSize

The encryption block size, in bytes. The size of data to be encrypted must be a multiple of this value.

ProtectedMemorySize

The total amount of memory, in bytes, that can be used to hold protected surfaces.
