Public Enum PlayReadyHardwareDRMFeatures

Inheritance: Enum
PlayReadyHardwareDRMFeatures

Attributes: ContractVersionAttribute

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Fields

Name	Value	Description
HardwareDRM	1	Hardware DRM is supported on the machine.
HEVC	2	Indicates the hardware supports High Efficiency Video Coding (HEVC)/H.265 codec.
Aes128Cbc	3	Indicates the hardware supports AES128CBC encryption.

Remarks

Starting with Windows 10, version 1709, you can detect support for AES128CBC hardware encryption on a device by calling PlayReadyStatics.CheckSupportedHardware and specifying the enumeration value Aes128Cbc. On previous versions of Windows 10, specifying this value will cause an exception to be thrown. For this reason, you should check for the presence of the enumeration value by calling ApiInformationIsApiContractPresent and specifying major contract version 5 before calling CheckSupportedHardware.

bool supportsAes128Cbc = ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 5);

if (supportsAes128Cbc)
{
    supportsAes128Cbc = PlayReadyStatics.CheckSupportedHardware(PlayReadyHardwareDRMFeatures.Aes128Cbc);
}
