VkVideoDecodeH264SessionParametersCreateInfoKHR

When a video session parameters object is created with the codec operation VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_KHR, the VkVideoSessionParametersCreateInfoKHR::pNext chain must include a VkVideoDecodeH264SessionParametersCreateInfoKHR structure specifying the capacity and initial contents of the object.

The VkVideoDecodeH264SessionParametersCreateInfoKHR structure is defined as:

typedef struct VkVideoDecodeH264SessionParametersCreateInfoKHR {
    VkStructureType sType;
    const void* pNext;
    uint32_t maxStdSPSCount;
    uint32_t maxStdPPSCount;
    const VkVideoDecodeH264SessionParametersAddInfoKHR* pParametersAddInfo;
} VkVideoDecodeH264SessionParametersCreateInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• maxStdSPSCount is the maximum number of H.264 SPS entries the created VkVideoSessionParametersKHR can contain.
• maxStdPPSCount is the maximum number of H.264 PPS entries the created VkVideoSessionParametersKHR can contain.
• pParametersAddInfo is NULL or a pointer to a VkVideoDecodeH264SessionParametersAddInfoKHR structure specifying H.264 parameters to add upon object creation.
