View the official Windows Driver Kit DDI referenceNo description available.
The DXVAHDDDI_BLT_STATE_PRIVATE_DATA structure describes data that specifies the private bit-block transfer (bitblt) state.
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.
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.
