The D3DDDIARG_CREATEEXTENSIONDEVICE structure describes a Microsoft DirectX Video Acceleration (DirectX VA) extension device to create.

Syntax

typedef struct _D3DDDIARG_CREATEEXTENSIONDEVICE {
  CONST GUID          *pGuid;
  DXVADDI_PRIVATEDATA *pPrivate;
  HANDLE              hExtension;
} D3DDDIARG_CREATEEXTENSIONDEVICE;

Members

pGuid

[in] A pointer to the GUID that represents the DirectX VA extension type. The Microsoft Direct3D runtime calls the GetCaps function to query for the supported extension GUIDs.

pPrivate

[in] A pointer to the DXVADDI_PRIVATEDATA structure that contains data that the driver requires to create the extension device.

hExtension

[in/out] A handle to the extension device. The user-mode display driver must set this handle to a value that the Direct3D runtime can use to identify the extension device in subsequent calls.
