## Name

VkVideoEncodeH265QuantizationMapCapabilitiesKHR - Structure describing H.265 encode quantization map capabilities

Loading… please wait.

## C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities of an H.265 encode profile, the `VkVideoEncodeH265QuantizationMapCapabilitiesKHR` structure can be included in the `pNext` chain of the VkVideoCapabilitiesKHR structure to retrieve additional video encode quantization map capabilities specific to H.265 encode profiles.

The `VkVideoEncodeH265QuantizationMapCapabilitiesKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_h265 with VK_KHR_video_encode_quantization_map
    typedef struct VkVideoEncodeH265QuantizationMapCapabilitiesKHR {
        VkStructureType    sType;
        void*              pNext;
        int32_t            minQpDelta;
        int32_t            maxQpDelta;
    } VkVideoEncodeH265QuantizationMapCapabilitiesKHR;

## Members

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

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

- `minQpDelta` indicates the minimum QP delta value supported for H.265 QP delta maps.

- `maxQpDelta` indicates the maximum QP delta value supported for H.265 QP delta maps.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeH265QuantizationMapCapabilitiesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_QUANTIZATION_MAP_CAPABILITIES_KHR

Structure Chaining
