VkVideoDecodeH264ProfileInfoKHR(3)

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
