# VkVideoDecodeH264ProfileInfoKHR(3) Manual Page

## Name

VkVideoDecodeH264ProfileInfoKHR - Structure specifying H.264 decode-specific video profile parameters

## C Specification

A video profile supporting H.264 video decode operations is specified by setting VkVideoProfileInfoKHR::`videoCodecOperation` to VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_KHR and adding a `VkVideoDecodeH264ProfileInfoKHR` structure to the VkVideoProfileInfoKHR::`pNext` chain.

The `VkVideoDecodeH264ProfileInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_h264
    typedef struct VkVideoDecodeH264ProfileInfoKHR {
        VkStructureType                              sType;
        const void*                                  pNext;
        StdVideoH264ProfileIdc                       stdProfileIdc;
        VkVideoDecodeH264PictureLayoutFlagBitsKHR    pictureLayout;
    } VkVideoDecodeH264ProfileInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `stdProfileIdc` is a `StdVideoH264ProfileIdc` value specifying the H.264 codec profile IDC, where enum constant `STD_VIDEO_H264_PROFILE_IDC_BASELINE` identifies the Constrained Baseline profile as defined in A.2.1.1 of the ITU-T H.264 Specification, and all other values correspond to profiles defined in section A.2 of the ITU-T H.264 Specification.

- `pictureLayout` is a VkVideoDecodeH264PictureLayoutFlagBitsKHR value specifying the picture layout used by the H.264 video sequence to be decoded.

## Description

Valid Usage (Implicit)

- VUID-VkVideoDecodeH264ProfileInfoKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_PROFILE_INFO_KHR

- VUID-VkVideoDecodeH264ProfileInfoKHR-pictureLayout-parameter
  If `pictureLayout` is not `0`, `pictureLayout` must be a valid VkVideoDecodeH264PictureLayoutFlagBitsKHR value
