# VkVideoEncodeQuantizationMapCapabilitiesKHR(3) Manual Page

## Name

VkVideoEncodeQuantizationMapCapabilitiesKHR - Structure describing video encode quantization map capabilities for a video profile

Loading… please wait.

## C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR with `pVideoProfile->videoCodecOperation` specifying an encode operation, the VkVideoEncodeQuantizationMapCapabilitiesKHR structure can be included in the `pNext` chain of the VkVideoCapabilitiesKHR structure to retrieve capabilities specific to video encode quantization maps.

The `VkVideoEncodeQuantizationMapCapabilitiesKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_quantization_map
    typedef struct VkVideoEncodeQuantizationMapCapabilitiesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkExtent2D         maxQuantizationMapExtent;
    } VkVideoEncodeQuantizationMapCapabilitiesKHR;

## Members

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

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

- `maxQuantizationMapExtent` indicates the maximum supported width and height of quantization maps.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeQuantizationMapCapabilitiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_QUANTIZATION_MAP_CAPABILITIES_KHR`
