# VkVideoDecodeAV1InlineSessionParametersInfoKHR(3) Manual Page

## Name

VkVideoDecodeAV1InlineSessionParametersInfoKHR - Structure specifies inline AV1 decoder parameter set information

Loading… please wait.

## C Specification

The `VkVideoDecodeAV1InlineSessionParametersInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_av1 with VK_KHR_video_maintenance2
    typedef struct VkVideoDecodeAV1InlineSessionParametersInfoKHR {
        VkStructureType                     sType;
        const void*                         pNext;
        const StdVideoAV1SequenceHeader*    pStdSequenceHeader;
    } VkVideoDecodeAV1InlineSessionParametersInfoKHR;

## Members

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

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

- `pStdSequenceHeader` is `NULL` or a pointer to an instance of the `StdVideoAV1SequenceHeader` structure describing the active AV1 sequence header.

## Description

If `pStdSequenceHeader` is not `NULL`, the issued video decode operations will use the specified sequence header parameters instead of the active sequence header being sourced from the bound video session parameters object.

Valid Usage (Implicit)

- VUID-VkVideoDecodeAV1InlineSessionParametersInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_AV1_INLINE_SESSION_PARAMETERS_INFO_KHR`

- VUID-VkVideoDecodeAV1InlineSessionParametersInfoKHR-pStdSequenceHeader-parameter
  If `pStdSequenceHeader` is not `NULL`, `pStdSequenceHeader` must be a valid pointer to a valid `StdVideoAV1SequenceHeader` value
