VkPhysicalDeviceVideoMaintenance2FeaturesKHR(3)

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:

    • 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
