C Specification
The VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR structure is
defined as:
// Provided by VK_KHR_unified_image_layouts
typedef struct VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           unifiedImageLayouts;
    VkBool32           unifiedImageLayoutsVideo;
} VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR;Members
This structure describes the following feature:
- 
sTypeis a VkStructureType value identifying this structure.
- 
pNextisNULLor a pointer to a structure extending this structure.
- 
unifiedImageLayoutsspecifies whether usage ofVK_IMAGE_LAYOUT_GENERAL, where valid, incurs no loss in efficiency. Additionally, it indicates whether it can be used in place ofVK_IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT.
- 
unifiedImageLayoutsVideospecifies whetherVK_IMAGE_LAYOUT_GENERALcan be used in place of any of the following image layouts with no loss in efficiency.- 
VK_IMAGE_LAYOUT_VIDEO_DECODE_DST_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_DECODE_SRC_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_DECODE_DPB_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_ENCODE_DST_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_ENCODE_SRC_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_ENCODE_DPB_KHR
- 
VK_IMAGE_LAYOUT_VIDEO_ENCODE_QUANTIZATION_MAP_KHR

Description
If the VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR 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 VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR, 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.
