# VkVideoDecodeUsageInfoKHR(3) Manual Page

## Name

VkVideoDecodeUsageInfoKHR - Structure specifying video decode usage information

Loading… please wait.

## C Specification

Additional information about the video decode use case can be provided by adding a `VkVideoDecodeUsageInfoKHR` structure to the `pNext` chain of VkVideoProfileInfoKHR.

The `VkVideoDecodeUsageInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_queue
    typedef struct VkVideoDecodeUsageInfoKHR {
        VkStructureType               sType;
        const void*                   pNext;
        VkVideoDecodeUsageFlagsKHR    videoUsageHints;
    } VkVideoDecodeUsageInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `videoUsageHints` is a bitmask of VkVideoDecodeUsageFlagBitsKHR specifying hints about the intended use of the video decode profile.

## Description

Valid Usage (Implicit)

- VUID-VkVideoDecodeUsageInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_USAGE_INFO_KHR`

- VUID-VkVideoDecodeUsageInfoKHR-videoUsageHints-parameter
  `videoUsageHints` must be a valid combination of VkVideoDecodeUsageFlagBitsKHR values
