# VkVideoEncodeH264SessionCreateInfoKHR(3) Manual Page

## Name

VkVideoEncodeH264SessionCreateInfoKHR - Structure specifies H.264 encode session parameters

Loading… please wait.

## 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 `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`
