# VkVideoEncodeH265SessionParametersCreateInfoKHR(3) Manual Page

## Name

VkVideoEncodeH265SessionParametersCreateInfoKHR - Structure specifies H.265 encoder parameter set information

Loading… please wait.

## C Specification

When a video session parameters object is created with the codec operation `VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_KHR`, the VkVideoSessionParametersCreateInfoKHR::`pNext` chain must include a `VkVideoEncodeH265SessionParametersCreateInfoKHR` structure specifying the capacity and initial contents of the object.

The `VkVideoEncodeH265SessionParametersCreateInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_h265
    typedef struct VkVideoEncodeH265SessionParametersCreateInfoKHR {
        VkStructureType                                        sType;
        const void*                                            pNext;
        uint32_t                                               maxStdVPSCount;
        uint32_t                                               maxStdSPSCount;
        uint32_t                                               maxStdPPSCount;
        const VkVideoEncodeH265SessionParametersAddInfoKHR*    pParametersAddInfo;
    } VkVideoEncodeH265SessionParametersCreateInfoKHR;

## Members

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

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

- `maxStdVPSCount` is the maximum number of H.265 VPS entries the created `VkVideoSessionParametersKHR` can contain.

- `maxStdSPSCount` is the maximum number of H.265 SPS entries the created `VkVideoSessionParametersKHR` can contain.

- `maxStdPPSCount` is the maximum number of H.265 PPS entries the created `VkVideoSessionParametersKHR` can contain.

- `pParametersAddInfo` is `NULL` or a pointer to a VkVideoEncodeH265SessionParametersAddInfoKHR structure specifying H.265 parameters to add upon object creation.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeH265SessionParametersCreateInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_SESSION_PARAMETERS_CREATE_INFO_KHR`

- VUID-VkVideoEncodeH265SessionParametersCreateInfoKHR-pParametersAddInfo-parameter
  If `pParametersAddInfo` is not `NULL`, `pParametersAddInfo` must be a valid pointer to a valid VkVideoEncodeH265SessionParametersAddInfoKHR structure
