I think this section needs to be as below:

static const NvencValuePair nvenc_h265_level_pairs[] = {
    { "auto", NV_ENC_LEVEL_AUTOSELECT },
    { "6"   , NV_ENC_LEVEL_HEVC_6     },
    { "6.0" , NV_ENC_LEVEL_HEVC_6     },
    { "6.1" , NV_ENC_LEVEL_HEVC_61    },
    { "6.2" , NV_ENC_LEVEL_HEVC_62    },
    { NULL }
};
