C Specification

The VkVideoEncodeH264SessionCreateInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_h264
typedef struct VkVideoEncodeH264SessionCreateInfoKHR {
    VkStructureType         sType;
    const void*             pNext;
    VkBool32                useMaxLevelIdc;
    StdVideoH264LevelIdc    maxLevelIdc;
} VkVideoEncodeH264SessionCreateInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • useMaxLevelIdc indicates whether the value of maxLevelIdc should be used by the implementation. When it is set to VK_FALSE, the implementation ignores the value of maxLevelIdc and uses the value of VkVideoEncodeH264CapabilitiesKHR::maxLevelIdc, as reported by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile.

  • maxLevelIdc is a StdVideoH264LevelIdc value specifying the upper bound on the H.264 level for the video bitstreams produced by the created video session, where enum constant STD_VIDEO_H264_LEVEL_IDC_<major>_<minor> identifies H.264 level <major>.<minor> as defined in section A.3 of the ITU-T H.264 Specification.

Description

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH264SessionCreateInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_SESSION_CREATE_INFO_KHR
