# VkVideoDecodeAV1CapabilitiesKHR(3) Manual Page

## Name

VkVideoDecodeAV1CapabilitiesKHR - Structure describing AV1 decode capabilities

Loading… please wait.

## C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities for an AV1 decode profile, the VkVideoCapabilitiesKHR::`pNext` chain must include a `VkVideoDecodeAV1CapabilitiesKHR` structure that will be filled with the profile-specific capabilities.

The `VkVideoDecodeAV1CapabilitiesKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_av1
    typedef struct VkVideoDecodeAV1CapabilitiesKHR {
        VkStructureType     sType;
        void*               pNext;
        StdVideoAV1Level    maxLevel;
    } VkVideoDecodeAV1CapabilitiesKHR;

## Members

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

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

- `maxLevel` is a `StdVideoAV1Level` value specifying the maximum AV1 level supported by the profile, as defined in section A.3 of the AV1 Specification.

## Description

Valid Usage (Implicit)

- VUID-VkVideoDecodeAV1CapabilitiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_AV1_CAPABILITIES_KHR`
