PFND3DDDI_DESTROYVIDEOPROCESSDEVICE callback function

Description

The DestroyVideoProcessDevice function releases resources for a Microsoft DirectX Video Acceleration (VA) video processing device.

Parameters

`hDevice`

A handle to the display device (graphics context).

`hVideoProcessor`

A handle to the DirectX VA video processing device that was created by the CreateVideoProcessDevice function.

Return value

DestroyVideoProcessDevice should return S_OK or an appropriate error result if it cannot successfully release resources for the DirectX VA decode device.

Remarks

The DestroyVideoProcessDevice function notifies the driver to destroy the handle to the DirectX VA video processing device that the CreateVideoProcessDevice function previously created. The driver can then release resources that are associated with the DirectX VA video processing device handle.
