C Specification
When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the
capabilities of an AV1 encode profile, the
VkVideoEncodeAV1QuantizationMapCapabilitiesKHR
structure can be
included in the pNext
chain of the VkVideoCapabilitiesKHR
structure to retrieve additional video encode quantization map capabilities
specific to AV1 encode profiles.
The VkVideoEncodeAV1QuantizationMapCapabilitiesKHR
structure is
defined as:
// Provided by VK_KHR_video_encode_av1 with VK_KHR_video_encode_quantization_map
typedef struct VkVideoEncodeAV1QuantizationMapCapabilitiesKHR {
VkStructureType sType;
void* pNext;
int32_t minQIndexDelta;
int32_t maxQIndexDelta;
} VkVideoEncodeAV1QuantizationMapCapabilitiesKHR;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
minQIndexDelta
indicates the minimum quantizer index delta value supported for AV1 quantizer index delta maps. -
maxQIndexDelta
indicates the maximum quantizer index delta value supported for AV1 quantizer index delta maps.
