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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceVideoEncodeQuantizationMapFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
