C Specification

The VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_queue
typedef struct VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR {
    VkStructureType                 sType;
    const void*                     pNext;
    const VkVideoProfileInfoKHR*    pVideoProfile;
    uint32_t                        qualityLevel;
} VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • pVideoProfile is a pointer to a VkVideoProfileInfoKHR structure specifying the video profile to query the video encode quality level properties for.

  • qualityLevel is the video encode quality level to query properties for.

Description

Valid Usage

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-pVideoProfile-08259
    pVideoProfile must be a supported video profile

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-pVideoProfile-08260
    pVideoProfile->videoCodecOperation must specify an encode operation

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-qualityLevel-08261
    qualityLevel must be less than VkVideoEncodeCapabilitiesKHR::maxQualityLevels, as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile specified in pVideoProfile

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VIDEO_ENCODE_QUALITY_LEVEL_INFO_KHR

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkPhysicalDeviceVideoEncodeQualityLevelInfoKHR-pVideoProfile-parameter
    pVideoProfile must be a valid pointer to a valid VkVideoProfileInfoKHR structure
