VkVideoEncodeAV1SessionParametersCreateInfoKHR

When a video session parameters object is created with the codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_AV1_BIT_KHR, the VkVideoSessionParametersCreateInfoKHR::pNext chain must include a VkVideoEncodeAV1SessionParametersCreateInfoKHR structure specifying the contents of the object.

The VkVideoEncodeAV1SessionParametersCreateInfoKHR structure is defined as:

typedef struct VkVideoEncodeAV1SessionParametersCreateInfoKHR {
    VkStructureType sType;
    const void* pNext;
    const StdVideoAV1SequenceHeader* pStdSequenceHeader;
    const StdVideoEncodeAV1DecoderModelInfo* pStdDecoderModelInfo;
    uint32_t stdOperatingPointCount;
    const StdVideoEncodeAV1OperatingPointInfo* pStdOperatingPoints;
} VkVideoEncodeAV1SessionParametersCreateInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• pStdSequenceHeader is a pointer to a StdVideoAV1SequenceHeader structure describing parameters of the AV1 sequence header entry to store in the created object.
• pStdDecoderModelInfo is NULL or a pointer to a StdVideoEncodeAV1DecoderModelInfo structure specifying the AV1 decoder model information to store in the created object.
• stdOperatingPointCount is the number of elements in the pStdOperatingPoints array.
• pStdOperatingPoints is NULL or a pointer to an array of stdOperatingPointCount number of StdVideoEncodeAV1OperatingPointInfo structures specifying the AV1 operating point information to store in the created object. Each element i specifies the parameter values corresponding to element i of the syntax elements defined in section 6.4 of the AV1 Specification.
