VkAndroidHardwareBufferFormatProperties2ANDROID(3)

Name

VkAndroidHardwareBufferFormatProperties2ANDROID - Structure describing the image format properties of an Android hardware buffer

C Specification

The format properties of an Android hardware buffer can be obtained by including a VkAndroidHardwareBufferFormatProperties2ANDROID structure in the pNext chain of the VkAndroidHardwareBufferPropertiesANDROID structure passed to vkGetAndroidHardwareBufferPropertiesANDROID. This structure is defined as:

// Provided by VK_ANDROID_external_memory_android_hardware_buffer with VK_KHR_format_feature_flags2 or VK_VERSION_1_3
typedef struct VkAndroidHardwareBufferFormatProperties2ANDROID {
    VkStructureType                  sType;
    void*                            pNext;
    VkFormat                         format;
    uint64_t                         externalFormat;
    VkFormatFeatureFlags2            formatFeatures;
    VkComponentMapping               samplerYcbcrConversionComponents;
    VkSamplerYcbcrModelConversion    suggestedYcbcrModel;
    VkSamplerYcbcrRange              suggestedYcbcrRange;
    VkChromaLocation                 suggestedXChromaOffset;
    VkChromaLocation                 suggestedYChromaOffset;
} VkAndroidHardwareBufferFormatProperties2ANDROID;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
format is the Vulkan format corresponding to the Android hardware buffer’s format, or VK_FORMAT_UNDEFINED if there is not an equivalent Vulkan format.
externalFormat is an implementation-defined external format identifier for use with VkExternalFormatANDROID. It must not be zero.
formatFeatures describes the capabilities of this external format when used with an image bound to memory imported from buffer.
samplerYcbcrConversionComponents is the component swizzle that should be used in VkSamplerYcbcrConversionCreateInfo.
suggestedYcbcrModel is a suggested color model to use in the VkSamplerYcbcrConversionCreateInfo.
suggestedYcbcrRange is a suggested numerical value range to use in VkSamplerYcbcrConversionCreateInfo.
suggestedXChromaOffset is a suggested X chroma offset to use in VkSamplerYcbcrConversionCreateInfo.
suggestedYChromaOffset is a suggested Y chroma offset to use in VkSamplerYcbcrConversionCreateInfo.

Description

The bits reported in formatFeatures must include the bits reported in the corresponding fields of VkAndroidHardwareBufferFormatPropertiesANDROID::formatFeatures.

Valid Usage (Implicit)

VUID-VkAndroidHardwareBufferFormatProperties2ANDROID-sType-sType
sType must be VK_STRUCTURE_TYPE_ANDROID_HARDWARE_BUFFER_FORMAT_PROPERTIES_2_ANDROID
