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.
