PFND3D11_1DDI_GETCONTENTPROTECTIONCAPS callback function (d3d10umddi.h)

  • Article

Queries the available content protection for a specified encryption algorithm and video decoder profile.

Syntax

PFND3D11_1DDI_GETCONTENTPROTECTIONCAPS Pfnd3d111DdiGetcontentprotectioncaps;

HRESULT Pfnd3d111DdiGetcontentprotectioncaps(
  D3D10DDI_HDEVICE hDevice,
  const GUID *pCryptoType,
  const GUID *pDecodeProfile,
  D3D11_1DDI_VIDEO_CONTENT_PROTECTION_CAPS *pCaps
)
{...}

Parameters

hDevice

A handle to the display device (graphics context).

pCryptoType

A pointer to a GUID that specifies the type of encryption algorithm to query.

pDecodeProfile

A pointer to a GUID that specifies the decoder profile to query.

pCaps

A pointer to a D3D11_1DDI_VIDEO_CONTENT_PROTECTION_CAPS structure that contains the protection capabilities for the specified encryption algorithm and decoder profile.

Return value

GetContentProtectionCaps returns one of the following values:

Return code Description
S_OK The content protection capabilities were queried successfully.
D3DERR_INVALID_CRYPTO The encryption algorithm specified by the pCryptoType parameter is not supported.

Remarks

The pCryptoType parameter can contain one of the following values:

  • D3DCRYPTOTYPE_AES128_CTR if the driver is configured to use the 128-bit Advanced Encryption Standard CTR mode (AES-CTR) block cipher.

  • D3DCRYPTOTYPE_PROPRIETARY if the driver is configured to use a proprietary encryption algorithm.

  • NULL_GUID if the driver is not configured to use any encryption algorithm.

Note

 The Microsoft Direct3D runtime verifies that the pDecodeProfile and pCryptoType parameter data is valid before it calls the GetContentProtectionCaps function.

Requirements

Requirement Value
Minimum supported client Windows 8
Minimum supported server Windows Server 2012
Target Platform Desktop
Header d3d10umddi.h (include D3d10umddi.h)
