DXVAHDDDI_BLT_STATE_PRIVATE_DATA structure

The DXVAHDDDI_BLT_STATE_PRIVATE_DATA structure describes data that specifies the private bit-block transfer (bitblt) state.

Syntax


typedef struct _DXVAHDDDI_BLT_STATE_PRIVATE_DATA {
  GUID Guid;
  UINT DataSize;
  VOID *pData;
} DXVAHDDDI_BLT_STATE_PRIVATE_DATA;

Members

Guid

[in] A GUID that identifies the private bitblt state.

DataSize

[in] The size, in bytes, of the private bitblt state data.

pData

[in/out] A pointer to the private bitblt state data. The caller sets pData to NULL to retrieve the size of the private bitblt state data.

Remarks

Unlike other bitblt states (DXVAHDDDI_BLT_STATE), the Direct3D runtime does not maintain the private bitblt state. An application and the driver communicate the private bitblt state directly in a proprietary manner, which consists of setting and retrieving the private bitblt state. To set private bitblt state, the application causes the Direct3D runtime to specify the DXVAHDDDI_BLT_STATE_PRIVATE state in the State member of the D3DDDIARG_DXVAHD_SETVIDEOPROCESSBLTSTATE structure in a call to the driver's SetVideoProcessBltState function. To retrieve private bitblt state, the application causes the Direct3D runtime to call the driver's GetVideoProcessBltStatePrivate function.

Requirements

Version

DXVAHDDDI_BLT_STATE_PRIVATE_DATA is supported beginning with the Windows 7 operating system.
