D3DDDIARG_EXTENSIONEXECUTE structure (d3dumddi.h)
The D3DDDIARG_EXTENSIONEXECUTE structure describes a Microsoft DirectX Video Acceleration (VA) extension operation to perform.
Syntax
typedef struct _D3DDDIARG_EXTENSIONEXECUTE {
[in] HANDLE hExtension;
[in] UINT Function;
[in] DXVADDI_PRIVATEDATA *pPrivateInput;
[in] DXVADDI_PRIVATEDATA *pPrivateOutput;
[in] UINT NumBuffers;
DXVADDI_PRIVATEBUFFER *pBuffers;
} D3DDDIARG_EXTENSIONEXECUTE;
Members
[in] hExtension
A handle to the DirectX VA extension device. The user-mode display driver returns this handle in a call to its CreateExtensionDevice function.
[in] Function
A specific operation to perform. The possible values for this member are defined by the extension device.
[in] pPrivateInput
A pointer to a DXVADDI_PRIVATEDATA structure that contains data that the driver requires to perform the extension operation.
[in] pPrivateOutput
A pointer to a DXVADDI_PRIVATEDATA structure that contains data about the extension operation that the driver returns.
[in] NumBuffers
The number of buffers in the list that is pointed to by pBuffers.
pBuffers
[in] A pointer to a list of DXVADDI_PRIVATEBUFFER structures that describe private buffers that an extension device uses to perform an extended operation.
