The D3DDDIARG_EXTENSIONEXECUTE structure describes a Microsoft DirectX Video Acceleration (VA) extension operation to perform.
hExtension [in]A handle to the DirectX VA extension device. The user-mode display driver returns this handle in a call to its CreateExtensionDevice function.
Function [in]A specific operation to perform. The possible values for this member are defined by the extension device.
pPrivateInput [in]A pointer to a DXVADDI_PRIVATEDATA structure that contains data that the driver requires to perform the extension operation.
pPrivateOutput [in]A pointer to a DXVADDI_PRIVATEDATA structure that contains data about the extension operation that the driver returns.
NumBuffers [in]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.
