C Specification
When calling vkGetPhysicalDeviceVideoCapabilitiesKHR with
pVideoProfile->videoCodecOperation
specifying an encode operation, the
VkVideoEncodeQuantizationMapCapabilitiesKHR structure can be included
in the pNext
chain of the VkVideoCapabilitiesKHR structure to
retrieve capabilities specific to video encode quantization maps.
The VkVideoEncodeQuantizationMapCapabilitiesKHR
structure is defined
as:
// Provided by VK_KHR_video_encode_quantization_map
typedef struct VkVideoEncodeQuantizationMapCapabilitiesKHR {
VkStructureType sType;
void* pNext;
VkExtent2D maxQuantizationMapExtent;
} VkVideoEncodeQuantizationMapCapabilitiesKHR;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
maxQuantizationMapExtent
indicates the maximum supported width and height of quantization maps.
