D3DDDIARG_DECODEEXTENSIONEXECUTE structure (d3dumddi.h)

  • Article

The D3DDDIARG_DECODEEXTENSIONEXECUTE structure describes a nonstandard Microsoft DirectX Video Acceleration (VA) decode operation to perform.

Syntax

typedef struct _D3DDDIARG_DECODEEXTENSIONEXECUTE {
  [in]  HANDLE                hDecode;
  [in]  UINT                  Function;
  [in]  DXVADDI_PRIVATEDATA   *pPrivateInput;
  [out] DXVADDI_PRIVATEDATA   *pPrivateOutput;
  [in]  UINT                  NumBuffers;
        DXVADDI_PRIVATEBUFFER *pBuffers;
} D3DDDIARG_DECODEEXTENSIONEXECUTE;

Members

[in] hDecode

A handle to the DirectX VA decode device. The user-mode display driver returns this handle in a call to its CreateDecodeDevice function.

[in] Function

A specific decode operation to perform. The possible values for this member are defined by the nonstandard decode device.

[in] pPrivateInput

A pointer to a DXVADDI_PRIVATEDATA structure that contains data that the driver requires to perform the decode operation.

[out] pPrivateOutput

A pointer to a DXVADDI_PRIVATEDATA structure that contains data about the decode 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 a nonstandard decoder uses to perform a decode operation.
