VkVideoSessionParametersUpdateInfoKHR(3)

# VkVideoSessionParametersUpdateInfoKHR(3) Manual Page

## Name

VkVideoSessionParametersUpdateInfoKHR - Structure specifying video session parameters update information

## C Specification

The `VkVideoSessionParametersUpdateInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_queue
    typedef struct VkVideoSessionParametersUpdateInfoKHR {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           updateSequenceCount;
    } VkVideoSessionParametersUpdateInfoKHR;

## Members

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

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

- `updateSequenceCount` is the new update sequence count to set for the video session parameters object.

## Description

Valid Usage (Implicit)

- VUID-VkVideoSessionParametersUpdateInfoKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_VIDEO_SESSION_PARAMETERS_UPDATE_INFO_KHR

- VUID-VkVideoSessionParametersUpdateInfoKHR-pNext-pNext
  Each `pNext` member of any structure (including this one) in the `pNext` chain must be either `NULL` or a pointer to a valid instance of VkVideoDecodeH264SessionParametersAddInfoKHR, VkVideoDecodeH265SessionParametersAddInfoKHR, VkVideoEncodeH264SessionParametersAddInfoKHR, or VkVideoEncodeH265SessionParametersAddInfoKHR

- VUID-VkVideoSessionParametersUpdateInfoKHR-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique
