VkPhysicalDeviceVideoMaintenance2FeaturesKHR(3)

# VkPhysicalDeviceVideoMaintenance2FeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceVideoMaintenance2FeaturesKHR - Structure describing the video maintenance features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceVideoMaintenance2FeaturesKHR` structure is defined as:

    // Provided by VK_KHR_video_maintenance2
    typedef struct VkPhysicalDeviceVideoMaintenance2FeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           videoMaintenance2;
    } VkPhysicalDeviceVideoMaintenance2FeaturesKHR;

## 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.

- `videoMaintenance2` specifies that the implementation supports the following:

  - Support for issuing video coding control commands against video decode sessions without a bound video session parameters object.

  - The new video session creation flag VK_VIDEO_SESSION_CREATE_INLINE_SESSION_PARAMETERS_BIT_KHR for video decode sessions.

  - Required support for the rate control mode VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DISABLED_BIT_KHR for the following video encode profiles:

    - H.264 encode profiles;

    - H.265 encode profiles;

    - AV1 encode profiles.

  - Additional guarantees on Video Std parameters used with video encode profiles that the implementations support without the need to override them.

## Description

If the `VkPhysicalDeviceVideoMaintenance2FeaturesKHR` 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 `VkPhysicalDeviceVideoMaintenance2FeaturesKHR`, 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-VkPhysicalDeviceVideoMaintenance2FeaturesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_MAINTENANCE_2_FEATURES_KHR

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo
