## C Specification

The structure VkVideoEncodeH264NaluSliceEXT representing a slice is defined as:

    // Provided by VK_EXT_video_encode_h264
    typedef struct VkVideoEncodeH264NaluSliceEXT {
        VkStructureType                           sType;
        const void*                               pNext;
        const StdVideoEncodeH264SliceHeader*      pSliceHeaderStd;
        uint32_t                                  mbCount;
        uint8_t                                   refFinalList0EntryCount;
        const VkVideoEncodeH264DpbSlotInfoEXT*    pRefFinalList0Entries;
        uint8_t                                   refFinalList1EntryCount;
        const VkVideoEncodeH264DpbSlotInfoEXT*    pRefFinalList1Entries;
        uint32_t                                  precedingNaluBytes;
        uint8_t                                   minQp;
        uint8_t                                   maxQp;
    } VkVideoEncodeH264NaluSliceEXT;
