C Specification

When a video session parameters object is created with the codec operation VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR, the VkVideoSessionParametersCreateInfoKHR::pNext chain must include a VkVideoDecodeH265SessionParametersCreateInfoKHR structure specifying the capacity and initial contents of the object.

The VkVideoDecodeH265SessionParametersCreateInfoKHR structure is defined as:

// Provided by VK_KHR_video_decode_h265
typedef struct VkVideoDecodeH265SessionParametersCreateInfoKHR {
    VkStructureType                                        sType;
    const void*                                            pNext;
    uint32_t                                               maxStdVPSCount;
    uint32_t                                               maxStdSPSCount;
    uint32_t                                               maxStdPPSCount;
    const VkVideoDecodeH265SessionParametersAddInfoKHR*    pParametersAddInfo;
} VkVideoDecodeH265SessionParametersCreateInfoKHR;

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 VkVideoDecodeH265SessionParametersAddInfoKHR structure specifying H.265 parameters to add upon object creation.

Description

Valid Usage (Implicit)
  • VUID-VkVideoDecodeH265SessionParametersCreateInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H265_SESSION_PARAMETERS_CREATE_INFO_KHR

  • VUID-VkVideoDecodeH265SessionParametersCreateInfoKHR-pParametersAddInfo-parameter
    If pParametersAddInfo is not NULL, pParametersAddInfo must be a valid pointer to a valid VkVideoDecodeH265SessionParametersAddInfoKHR structure
