# VkVideoDecodeH264SessionCreateInfoEXT(3) Manual Page

## Name

VkVideoDecodeH264SessionCreateInfoEXT - Structure specifies H.264 decode session creation parameters

Loading… please wait.

## C Specification

The instance of VkVideoDecodeH264SessionCreateInfoEXT structure can be chained to VkVideoSessionCreateInfoKHR when the function vkCreateVideoSessionKHR is called to create a video session for H.264 decode.

The VkVideoDecodeH264SessionCreateInfoEXT structure is defined as:

    // Provided by VK_EXT_video_decode_h264
    typedef struct VkVideoDecodeH264SessionCreateInfoEXT {
        VkStructureType                    sType;
        const void*                        pNext;
        VkVideoDecodeH264CreateFlagsEXT    flags;
        const VkExtensionProperties*       pStdExtensionVersion;
    } VkVideoDecodeH264SessionCreateInfoEXT;

## Members

- `sType` is the type of this structure.

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

- `flags` is reserved for future use.

- `pStdExtensionVersion` is the specific H.264 codec extensions defined in `StdVideoH264Extensions`.

## Description

Valid Usage (Implicit)

- VUID-VkVideoDecodeH264SessionCreateInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_SESSION_CREATE_INFO_EXT`

- VUID-VkVideoDecodeH264SessionCreateInfoEXT-flags-zerobitmask
  `flags` must be `0`

- VUID-VkVideoDecodeH264SessionCreateInfoEXT-pStdExtensionVersion-parameter
  `pStdExtensionVersion` must be a valid pointer to a valid VkExtensionProperties structure
