VkVideoEncodeQuantizationMapInfoKHR(3)

Name

VkVideoEncodeQuantizationMapInfoKHR - Structure specifying quantization map information to use for video encode operations

C Specification

The VkVideoEncodeQuantizationMapInfoKHR structure can be included in the pNext chain of the VkVideoEncodeInfoKHR structure passed to the vkCmdEncodeVideoKHR command to specify the quantization map used by the issued video encode operations.

The VkVideoEncodeQuantizationMapInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_quantization_map
typedef struct VkVideoEncodeQuantizationMapInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    VkImageView        quantizationMap;
    VkExtent2D         quantizationMapExtent;
} VkVideoEncodeQuantizationMapInfoKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
quantizationMap specifies the image view to use as the quantization map.
quantizationMapExtent specifies the extent of the image subregion of quantizationMap to use as the quantization map starting at offset (0,0).

Description

Valid Usage

VUID-VkVideoEncodeQuantizationMapInfoKHR-quantizationMapExtent-10352
quantizationMapExtent.width must be less than or equal to the width of quantizationMap
VUID-VkVideoEncodeQuantizationMapInfoKHR-quantizationMapExtent-10353
quantizationMapExtent.height must be less than or equal to the height of quantizationMap

Valid Usage (Implicit)

VUID-VkVideoEncodeQuantizationMapInfoKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_QUANTIZATION_MAP_INFO_KHR
VUID-VkVideoEncodeQuantizationMapInfoKHR-quantizationMap-parameter
If quantizationMap is not VK_NULL_HANDLE, quantizationMap must be a valid VkImageView handle
