# VkVideoEncodeSessionParametersFeedbackInfoKHR(3) Manual Page

## Name

VkVideoEncodeSessionParametersFeedbackInfoKHR - Structure providing feedback about the requested video session parameters

Loading… please wait.

## C Specification

The `VkVideoEncodeSessionParametersFeedbackInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_queue
    typedef struct VkVideoEncodeSessionParametersFeedbackInfoKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           hasOverrides;
    } VkVideoEncodeSessionParametersFeedbackInfoKHR;

## Members

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

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

- `hasOverrides` indicates whether any of the requested parameter data were overridden by the implementation.

## Description

Depending on the used video encode operation, additional codec-specific structures can be included in the `pNext` chain of this structure to capture codec-specific feedback information about the requested parameter data, as described in the corresponding sections.

Valid Usage (Implicit)

- VUID-VkVideoEncodeSessionParametersFeedbackInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_SESSION_PARAMETERS_FEEDBACK_INFO_KHR`

- VUID-VkVideoEncodeSessionParametersFeedbackInfoKHR-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 VkVideoEncodeH264SessionParametersFeedbackInfoKHR or VkVideoEncodeH265SessionParametersFeedbackInfoKHR

- VUID-VkVideoEncodeSessionParametersFeedbackInfoKHR-sType-unique
  The `sType` value of each struct in the `pNext` chain must be unique
