IDirect3DDevice9Video::GetContentProtectionCaps method

Queries the display driver for its content protection capabilities.

Syntax

HRESULT GetContentProtectionCaps(
   const GUID                     *pCryptoType,
   const GUID                     *pDecodeProfile,
         D3DCONTENTPROTECTIONCAPS *pCaps
);

Parameters

pCryptoType

A pointer to a GUID that specifies the type of encryption to use. The following GUIDs are defined.

D3DCRYPTOTYPE_AES128_CTR (128-bit Advanced Encryption Standard CTR mode (AES-CTR) block cipher.)

D3DCRYPTOTYPE_PROPRIETARY (Proprietary encryption algorithm.)

pDecodeProfile

A pointer to a GUID that specifies the DirectX Video Acceleration 2 (DXVA-2) decoding profile. For a list of possible values, see IDirectXVideoDecoderService::GetDecoderDeviceGuids. If DXVA-2 decoding will not be used, set this parameter to NULL.

pCaps

A pointer to a D3DCONTENTPROTECTIONCAPS structure. The method fills in this structure with the driver's content protection capabilities.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
