## Name

VkVideoDecodeAV1ProfileInfoKHR - Structure specifying AV1 decode profile

Loading… please wait.

## C Specification

A video profile supporting AV1 video decode operations is specified by setting VkVideoProfileInfoKHR::`videoCodecOperation` to `VK_VIDEO_CODEC_OPERATION_DECODE_AV1_BIT_KHR` and adding a `VkVideoDecodeAV1ProfileInfoKHR` structure to the VkVideoProfileInfoKHR::`pNext` chain.

The `VkVideoDecodeAV1ProfileInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_av1
    typedef struct VkVideoDecodeAV1ProfileInfoKHR {
        VkStructureType       sType;
        const void*           pNext;
        StdVideoAV1Profile    stdProfile;
        VkBool32              filmGrainSupport;
    } VkVideoDecodeAV1ProfileInfoKHR;

## Members

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

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

- `stdProfile` is a `StdVideoAV1Profile` value specifying the AV1 codec profile, as defined in section A.2 of the AV1 Specification.

- `filmGrainSupport` specifies whether AV1 film grain, as defined in section 7.8.3 of the AV1 Specification, can be used with the video profile. When this member is `VK_TRUE`, video session objects created against the video profile will be able to decode pictures that have film grain enabled.

## Description

Note | Enabling `filmGrainSupport` may increase the memory requirements of video sessions and/or video picture resources on some implementations.

Valid Usage (Implicit)

- VUID-VkVideoDecodeAV1ProfileInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_AV1_PROFILE_INFO_KHR`
