VkAndroidHardwareBufferFormatResolvePropertiesANDROID

The VkAndroidHardwareBufferFormatResolvePropertiesANDROID structure is defined as:

typedef struct VkAndroidHardwareBufferFormatResolvePropertiesANDROID {
    VkStructureType sType;
    void* pNext;
    VkFormat colorAttachmentFormat;
} VkAndroidHardwareBufferFormatResolvePropertiesANDROID;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• colorAttachmentFormat is a VkFormat specifying the format of color attachment images that must be used for color attachments when resolving to the specified external format. If the implementation supports external format resolves for the specified external format, this value will be a color format supporting the VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT in VkFormatProperties::optimalTilingFeatures as returned by vkGetPhysicalDeviceFormatProperties with format equal to colorAttachmentFormat If external format resolves are not supported, this value will be VK_FORMAT_UNDEFINED.

Any Android hardware buffer created with the GRALLOC_USAGE_HW_RENDER flag must be renderable in some way in Vulkan, either:

• VkAndroidHardwareBufferFormatPropertiesANDROID::format must be a format that supports VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT or VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT in VkFormatProperties::optimalTilingFeatures; or
• colorAttachmentFormat must be a format that supports VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT in VkFormatProperties::optimalTilingFeatures.
