# VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR - Structure describing the video encode quantization map features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_quantization_map
    typedef struct VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           videoEncodeQuantizationMap;
    } VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR;

## Members

This structure describes the following features:

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

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

- `videoEncodeQuantizationMap` indicates that the implementation supports video encode quantization maps.

  Note | Support for `videoEncodeQuantizationMap` does not indicate that all video encode profiles support quantization maps. Support for quantization maps for any specific video encode profile is subject to video-profile-specific capabilities.

## Description

If the `VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_ENCODE_QUANTIZATION_MAP_FEATURES_KHR`
