D3DDDIARG_CREATEVIDEOPROCESSDEVICE structure
The D3DDDIARG_CREATEVIDEOPROCESSDEVICE structure describes a Microsoft DirectX Video Acceleration (DirectX VA) video processing device to create.
Syntax
typedef struct _D3DDDIARG_CREATEVIDEOPROCESSDEVICE { const GUID *pVideoProcGuid; DXVADDI_VIDEODESC VideoDesc; D3DDDIFORMAT RenderTargetFormat; UINT MaxSubStreams; HANDLE hVideoProcess; } D3DDDIARG_CREATEVIDEOPROCESSDEVICE;
Members
- pVideoProcGuid
-
[in] A pointer to the GUID that represents a DirectX VA video processing device to create. The Microsoft Direct3D runtime can call the user-mode display driver's GetCaps function to query for the video processing GUIDs that the driver supports.
- VideoDesc
-
[in] The DXVADDI_VIDEODESC structure for the video stream that the video processing device should process.
- RenderTargetFormat
-
[in] A D3DDDIFORMAT-typed value that indicates the pixel format of the render target for the video processing device.
- MaxSubStreams
-
[in] The maximum number of video substreams that can be sent to the video processing device. If this value is set to zero, the device never receives any video substreams.
- hVideoProcess
-
[in/out] A handle to the video processing device. The user-mode display driver must set this handle to a value that the Microsoft Direct3D runtime can use to identify the video processing device in subsequent calls.
