海思VB初始化出错HI_MPI_VB_SetConf failed=-1!

我查看一下了/proc # cat media-mem

请问各位大神看出什么问题来了吗

我的vb代码是：
memset(&stVbConf, 0, sizeof(VB_CONFIG_S));
stVbConf.u32MaxPoolCnt = 128;
u32BlkSize = AVS_GetPicBufferSize(3840, 2160, COMPRESS_MODE_NONE, DEFAULT_ALIGN);
stVbConf.astCommPool[0].u64BlkSize = u32BlkSize;
stVbConf.astCommPool[0].u32BlkCnt = 16;
u32BlkSize = COMMON_GetPicBufferSize(u32OutW, u32OutH, PIXEL_FORMAT_YVU_SEMIPLANAR_420,
DATA_BITWIDTH_10, COMPRESS_MODE_SEG, DEFAULT_ALIGN);
stVbConf.astCommPool[1].u64BlkSize = u32BlkSize;
stVbConf.astCommPool[1].u32BlkCnt = 20;
u32BlkSize = VI_GetRawBufferSize(3840, 2160, PIXEL_FORMAT_RGB_BAYER_16BPP,
COMPRESS_MODE_LINE, DEFAULT_ALIGN);
stVbConf.astCommPool[2].u64BlkSize = u32BlkSize;
stVbConf.astCommPool[2].u32BlkCnt = u32ViChnCnt * 3;
s32Ret = SAMPLE_COMM_SYS_Init(&stVbConf);

没人讨论吗

楼主解决了吗？我运行demo也出了这个问题

找到原因了，是没启动mpp业务
运行前执行
cd mpp/out/linux/multi-core/ko
./load3559av100_multicore -i -sensor0 imx477 -sensor1 imx477
然后
cd mpp/sample/vio
./sample_vio 0 0

兄弟 你解决了吗 我也遇到了这个问题【Hi3516 av300】提示：[ vb] [Func]:base_ioctl [Line]:2776 [Info]:ioctl cmd does NOT exit!
