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
