VkVideoDecodeH265SessionParametersAddInfoKHR(3)

C Specification

The VkVideoDecodeH265SessionParametersAddInfoKHR structure is defined as:

// Provided by VK_KHR_video_decode_h265
typedef struct VkVideoDecodeH265SessionParametersAddInfoKHR {
    VkStructureType                            sType;
    const void*                                pNext;
    uint32_t                                   stdVPSCount;
    const StdVideoH265VideoParameterSet*       pStdVPSs;
    uint32_t                                   stdSPSCount;
    const StdVideoH265SequenceParameterSet*    pStdSPSs;
    uint32_t                                   stdPPSCount;
    const StdVideoH265PictureParameterSet*     pStdPPSs;
} VkVideoDecodeH265SessionParametersAddInfoKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
stdVPSCount is the number of elements in the pStdVPSs array.
pStdVPSs is a pointer to an array of StdVideoH265VideoParameterSet structures describing the H.265 VPS entries to add.
stdSPSCount is the number of elements in the pStdSPSs array.
pStdSPSs is a pointer to an array of StdVideoH265SequenceParameterSet structures describing the H.265 SPS entries to add.
stdPPSCount is the number of elements in the pStdPPSs array.
pStdPPSs is a pointer to an array of StdVideoH265PictureParameterSet structures describing the H.265 PPS entries to add.

Description

This structure can be specified in the following places:

In the pParametersAddInfo member of the VkVideoDecodeH265SessionParametersCreateInfoKHR structure specified in the pNext chain of VkVideoSessionParametersCreateInfoKHR used to create a video session parameters object. In this case, if the video codec operation the video session parameters object is created with is VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR, then it defines the set of initial parameters to add to the created object (see Creating Video Session Parameters).
In the pNext chain of VkVideoSessionParametersUpdateInfoKHR. In this case, if the video codec operation the video session parameters object to be updated was created with is VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR, then it defines the set of parameters to add to it (see Updating Video Session Parameters).

Valid Usage

VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-None-04833
The vps_video_parameter_set_id member of each StdVideoH265VideoParameterSet structure specified in the elements of pStdVPSs must be unique within pStdVPSs
VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-None-04834
The pair constructed from the sps_video_parameter_set_id and sps_seq_parameter_set_id members of each StdVideoH265SequenceParameterSet structure specified in the elements of pStdSPSs must be unique within pStdSPSs
VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-None-04835
The triplet constructed from the sps_video_parameter_set_id, pps_seq_parameter_set_id, and pps_pic_parameter_set_id members of each StdVideoH265PictureParameterSet structure specified in the elements of pStdPPSs must be unique within pStdPPSs

Valid Usage (Implicit)

VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H265_SESSION_PARAMETERS_ADD_INFO_KHR
VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-pStdVPSs-parameter
If stdVPSCount is not 0, pStdVPSs must be a valid pointer to an array of stdVPSCount StdVideoH265VideoParameterSet values
VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-pStdSPSs-parameter
If stdSPSCount is not 0, pStdSPSs must be a valid pointer to an array of stdSPSCount StdVideoH265SequenceParameterSet values
VUID-VkVideoDecodeH265SessionParametersAddInfoKHR-pStdPPSs-parameter
If stdPPSCount is not 0, pStdPPSs must be a valid pointer to an array of stdPPSCount StdVideoH265PictureParameterSet values
