VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR(3)

# VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR - Structure describing the video encode intra refresh features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_intra_refresh
    typedef struct VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           videoEncodeIntraRefresh;
    } VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR;

## 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.

- `videoEncodeIntraRefresh` specifies that the implementation supports video encode intra refresh.

  Note | Support for `videoEncodeIntraRefresh` does not indicate that all video encode profiles support intra refresh. Support for intra refresh for any specific video encode profile is subject to video-profile-specific capabilities.

## Description

If the `VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR` 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 `VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR`, 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-VkPhysicalDeviceVideoEncodeIntraRefreshFeaturesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_ENCODE_INTRA_REFRESH_FEATURES_KHR

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
