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
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
formatis the Vulkan format corresponding to the Android hardware buffer’s format, or VK_FORMAT_UNDEFINED if there is not an equivalent Vulkan format. -
externalFormatis an implementation-defined external format identifier for use with VkExternalFormatANDROID. It must not be zero. -
formatFeaturesdescribes the capabilities of this external format when used with an image bound to memory imported frombuffer. -
samplerYcbcrConversionComponentsis the component swizzle that should be used in VkSamplerYcbcrConversionCreateInfo. -
suggestedYcbcrModelis a suggested color model to use in the VkSamplerYcbcrConversionCreateInfo. -
suggestedYcbcrRangeis a suggested numerical value range to use in VkSamplerYcbcrConversionCreateInfo. -
suggestedXChromaOffsetis a suggested X chroma offset to use in VkSamplerYcbcrConversionCreateInfo. -
suggestedYChromaOffsetis 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.
