VkVideoEncodeAV1SessionCreateInfoKHR(3)

# VkVideoEncodeAV1SessionCreateInfoKHR(3) Manual Page

## Name

VkVideoEncodeAV1SessionCreateInfoKHR - Structure specifies AV1 encode session parameters

## C Specification

The `VkVideoEncodeAV1SessionCreateInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_av1
    typedef struct VkVideoEncodeAV1SessionCreateInfoKHR {
        VkStructureType     sType;
        const void*         pNext;
        VkBool32            useMaxLevel;
        StdVideoAV1Level    maxLevel;
    } VkVideoEncodeAV1SessionCreateInfoKHR;

## Members

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

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

- `useMaxLevel` indicates whether the value of `maxLevel` should be used by the implementation. When it is set to VK_FALSE, the implementation ignores the value of `maxLevel` and uses the value of VkVideoEncodeAV1CapabilitiesKHR::`maxLevel`, as reported by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile.

- `maxLevel` is a `StdVideoAV1Level` value specifying the upper bound on the AV1 level for the video bitstreams produced by the created video session.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeAV1SessionCreateInfoKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_AV1_SESSION_CREATE_INFO_KHR
