C Specification
The VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR structure is
defined as:
// Provided by VK_KHR_video_encode_feedback2
typedef struct VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR {
VkStructureType sType;
void* pNext;
VkBool32 videoEncodeFeedback2;
} VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR;Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
videoEncodeFeedback2specifies that the implementation supports per picture partition feedback and the following additional video encode feedback flags, as reported in VkVideoEncodeFeedback2CapabilitiesKHR and/or VkVideoEncodeCapabilitiesKHR::supportedEncodeFeedbackFlags, respectively:-
VK_VIDEO_ENCODE_FEEDBACK_PICTURE_PARTITION_COUNT_BIT_KHR.
NoteSupport for
videoEncodeFeedback2does not indicate that all video encode profiles support per picture partition feedback and the new video encode feedback flags. Support for individual video encode profiles is subject to video-profile-specific capabilities.
Description
If the VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR 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 VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR, 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.
