1.MANER_NUM_TEN 没有定义，我定义的10 2.VT_SYS_RESOLUTION_MAX_WIDTH和VT_SYS_RESOLUTION_MAX_HEIGHT 也没有定义，我试过(2560,2560)和（1920，1080）两组值。3. VT_DECODER_VPSS_STATIC_CHN_ID没有定义，我定义的1.结果：1. 第一步 HI_MPI_VB_SetConfig 就返回出错（0xa0018012）2. HI_MPI_VPSS_GetModParam和HI_MPI_VPSS_SetModParam都返回出错（0xffffffff）3. 出现刷屏日志“[Func]:mpi_sys_check_bind_chn [Line]:163 [Info]:mod_id:24() is not supported ”4. HI_MPI_VDEC_SetChnParam 第一遍直接获取（HI_MPI_VDEC_GetChnParam）到的参数就设置，不出错5. HI_MPI_VDEC_SetChnParam 第二遍，在第一遍HI_MPI_VDEC_SetChnParam 之后只修改vdecChnParam.stVdecVideoParam.enDecMode = VIDEO_DEC_MODE_IPB; 报错（0xa0058003）主要是VIDEO_DEC_MODE_IPB一设置下去就报错（0xa0058003），是不是我的这台设备就不支持解码B帧？文档错误码：《0xA0058003 HI_ERR_VDEC_ILLEGAL_PARAM 参数超出合法范围》，注：HISICHECKRET(HI_MPI_VB_Init()); HISICHECKRET(HI_MPI_SYS_Init());这两个函数不调用就没有刷屏日志“[Func]:mpi_sys_check_bind_chn [Line]:163 [Info]:mod_id:24() is not supported”代码如下：{ { //1.
