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
isNULL
or a pointer to a structure extending this structure. -
videoEncodeQuantizationMap
indicates that the implementation supports video encode quantization maps.NoteSupport 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.
