VkVideoDecodeH264SessionParametersAddInfoKHR(3)

C Specification

The VkVideoDecodeH264SessionParametersAddInfoKHR structure is defined as:

// Provided by VK_KHR_video_decode_h264
typedef struct VkVideoDecodeH264SessionParametersAddInfoKHR {
    VkStructureType                            sType;
    const void*                                pNext;
    uint32_t                                   stdSPSCount;
    const StdVideoH264SequenceParameterSet*    pStdSPSs;
    uint32_t                                   stdPPSCount;
    const StdVideoH264PictureParameterSet*     pStdPPSs;
} VkVideoDecodeH264SessionParametersAddInfoKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
stdSPSCount is the number of elements in the pStdSPSs array.
pStdSPSs is a pointer to an array of StdVideoH264SequenceParameterSet structures describing the H.264 SPS entries to add.
stdPPSCount is the number of elements in the pStdPPSs array.
pStdPPSs is a pointer to an array of StdVideoH264PictureParameterSet structures describing the H.264 PPS entries to add.

Description

This structure can be specified in the following places:

In the pParametersAddInfo member of the VkVideoDecodeH264SessionParametersCreateInfoKHR 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_H264_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_H264_BIT_KHR, then it defines the set of parameters to add to it (see Updating Video Session Parameters).

Valid Usage

VUID-VkVideoDecodeH264SessionParametersAddInfoKHR-None-04825
The seq_parameter_set_id member of each StdVideoH264SequenceParameterSet structure specified in the elements of pStdSPSs must be unique within pStdSPSs
VUID-VkVideoDecodeH264SessionParametersAddInfoKHR-None-04826
The pair constructed from the seq_parameter_set_id and pic_parameter_set_id members of each StdVideoH264PictureParameterSet structure specified in the elements of pStdPPSs must be unique within pStdPPSs

Valid Usage (Implicit)

VUID-VkVideoDecodeH264SessionParametersAddInfoKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_SESSION_PARAMETERS_ADD_INFO_KHR
VUID-VkVideoDecodeH264SessionParametersAddInfoKHR-pStdSPSs-parameter
If stdSPSCount is not 0, pStdSPSs must be a valid pointer to an array of stdSPSCount StdVideoH264SequenceParameterSet values
VUID-VkVideoDecodeH264SessionParametersAddInfoKHR-pStdPPSs-parameter
If stdPPSCount is not 0, pStdPPSs must be a valid pointer to an array of stdPPSCount StdVideoH264PictureParameterSet values
