HI3521在VI后VPSS前保存一张图片

/ set max depth /
u32Depth = 10;
s32ret = HI_MPI_VI_SetFrameDepth(vichn,u32Depth);
if(HI_SUCCESS != s32ret)
{
printf(“set max depth err:0x%x\n”,s32ret);
return s32ret;
}

/ get video frame frame vi chn /
s32ret = HI_MPI_VI_GetFrame(vichn,&stFrame,HI_FALSE);
if(HI_SUCCESS != s32ret)
{
printf(“get vi frame err:0x%x\n”,s32ret);
return s32ret;
}

/ deal with video frame… /
fwrite(stFrame->stVFrame.u32PhyAddr[0],1,sizeof(stFrame->stVFrame.u32PhyAddr[0]),fd);
fwrite(stFrame->stVFrame.u32PhyAddr[1],1,sizeof(stFrame->stVFrame.u32PhyAddr[1]),fd);

/ release video frame /
(void)HI_MPI_VI_ReleaseFrame(vichn,&stFrame);
}

但是报错说stFrame->stVFrame.u32PhyAddr[0]和stFrame->stVFrame.u32PhyAddr[1]这两个参数无效
也不知道思路有没有问题，求求大佬们赐教
