D3DDDIARG_EXTENSIONEXECUTE structure (d3dumddi.h)

  • Article

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.
