VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR(3)

# VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR - Structure describing additional video encode feedback features that can be supported by an implementation

## 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:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `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.

    Note | 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.

## 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.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceVideoEncodeFeedback2FeaturesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_ENCODE_FEEDBACK_2_FEATURES_KHR

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
