Creates a cryptographic session to encrypt video content that is sent to the display driver.
Syntax
HRESULT CreateCryptoSession(
const GUID *pCryptoType,
const GUID *pDecodeProfile,
IDirect3DCryptoSession9 **ppCryptoSession,
HANDLE *pCryptoHandle
);
Parameters
pCryptoType
Pointer to a GUID that specifies the type of encryption to use. The following GUIDs are defined.
pDecodeProfile
Type: GUID
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
Type: D3DCONTENTPROTECTIONCAPS
A pointer to a D3DCONTENTPROTECTIONCAPS structure. The method fills in this structure with the driver's content protection capabilities.
pDecodeProfile
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.
ppCryptoSession
Receives a pointer to the IDirect3DCryptoSession9 interface. The caller must release the interface.
pCryptoHandle
Receives a handle for the session.
