VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR

The VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 videoEncodeFeedback2;
} VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR;

pub struct PhysicalDeviceVideoEncodeFeedback2FeaturesKHR {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    video_encode_feedback2: vk::Bool32,
}

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• FEATURES VIDEOENCODEFEEDBACK2
  videoEncodeFeedback2 specifies 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_AVERAGE_QUANTIZATION_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_MIN_QUANTIZATION_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_MAX_QUANTIZATION_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_INTRA_PIXELS_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_INTER_PIXELS_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_SKIPPED_PIXELS_BIT_KHR.
  • VK_VIDEO_ENCODE_FEEDBACK_PICTURE_PARTITION_COUNT_BIT_KHR.
    Support for videoEncodeFeedback2 does 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.

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.
