# VkVideoEncodeAV1QuantizationMapCapabilitiesKHR(3) Manual Page

## Name

VkVideoEncodeAV1QuantizationMapCapabilitiesKHR - Structure describing AV1 encode quantization map capabilities

Loading… please wait.

## C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities of an AV1 encode profile, the `VkVideoEncodeAV1QuantizationMapCapabilitiesKHR` structure can be included in the `pNext` chain of the VkVideoCapabilitiesKHR structure to retrieve additional video encode quantization map capabilities specific to AV1 encode profiles.

The `VkVideoEncodeAV1QuantizationMapCapabilitiesKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_av1 with VK_KHR_video_encode_quantization_map
    typedef struct VkVideoEncodeAV1QuantizationMapCapabilitiesKHR {
        VkStructureType    sType;
        void*              pNext;
        int32_t            minQIndexDelta;
        int32_t            maxQIndexDelta;
    } VkVideoEncodeAV1QuantizationMapCapabilitiesKHR;

## Members

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

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

- `minQIndexDelta` indicates the minimum quantizer index delta value supported for AV1 quantizer index delta maps.

- `maxQIndexDelta` indicates the maximum quantizer index delta value supported for AV1 quantizer index delta maps.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeAV1QuantizationMapCapabilitiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_AV1_QUANTIZATION_MAP_CAPABILITIES_KHR`
