ive resize sobel问题

利用ive的resize和sobel算子做图像处理，申请了两块mmz的空间，申请空间的时候没有报错，但是经过resize和sobel的时候就报错：
是怎么回事阿，我不知道是mmz空间的问题还是什么问题？？？？？？？？？？？？

<3>[ ive] [Func]:ive_sobel [Line]:388 [Info]:Error(0xa01d8007): check sobel parameters failed!
申请空间的代码：
hi_void create_img(hi_svp_img img,hi_svp_img_type type,hi_u32 width,hi_u32 height)
{
hi_s32 ret = HI_SUCCESS;
hi_u32 size;
hi_void virt = NULL;
size = widthheight;
ret = hi_mpi_sys_mmz_alloc((hi_phys_addr_t )&img->phys_addr[0],(hi_void **)&virt,
HI_NULL,HI_NULL,size);
if(ret != HI_SUCCESS)
{
printf(“hi_mpi_sys_mmz_alloc fail, ret = 0x%x\n”,ret);
}
img->width = width;
img->height = height;
img->stride[0] = width;
img->type = type;
img->virt_addr[0] = (hi_u64)virt;
}

resize的配置：
hi_s32 resize(hi_video_frame frame,hi_svp_img dst,hi_s32 width,hi_s32 height)
{
hi_s32 ret = HI_SUCCESS;
hi_ive_handle handle;
hi_svp_img src;
hi_ive_resize_ctrl ctrl;
hi_bool is_instant = TD_FALSE;
src.width = frame->width;
src.height = frame->height;
src.phys_addr[0] = frame->phys_addr[0];
src.virt_addr[0] = frame->virt_addr[0];
src.stride[0] = frame->stride[0];
src.type = OT_SVP_IMG_TYPE_U8C1;

dst->width = width;
dst->height = height;
dst->stride[0] = width;
dst->type = OT_SVP_IMG_TYPE_U8C1;

ctrl.mode = OT_IVE_RESIZE_MODE_LINEAR;
ctrl.num = 1;
ctrl.mem.phys_addr = dst->phys_addr[0];
ctrl.mem.virt_addr = dst->virt_addr[0];
ctrl.mem.size = (width*height);

ret = hi_mpi_ive_resize(&handle, &src, dst,&ctrl,is_instant);
if(ret == HI_FAILURE)
{
    printf("hi_mpi_ive_dma fail,ret = 0x%x\n",ret);
}

return ret;

}
sobel的配置：
hi_s32 sobel(hi_svp_src_img src,hi_svp_src_img dst_h,hi_svp_src_img *dst_v)
{
hi_s32 ret = HI_SUCCESS;
hi_ive_handle handle;
hi_bool is_instant = TD_FALSE;
hi_ive_sobel_ctrl ctrl;

hi_s8 mask[HI_IVE_MASK_NUM] =   {-1,-2 ,0, 2,1,
                                 -4,-8 ,0, 8,4,
                                 -6,-12,0,12,6,
                                 -4,-8 ,0, 8,4,
                                 -1,-2 ,0, 2,1};

memcpy(ctrl.mask,mask,HI_IVE_MASK_NUM); 
ctrl.out_ctrl = HI_IVE_SOBEL_OUT_CTRL_BOTH;

ret = hi_mpi_ive_sobel(&handle, src, dst_h,dst_v, &ctrl,is_instant);
if(ret == HI_FAILURE)
{
    printf("hi_mpi_ive_sobel fail,ret = 0x%x\n",ret);
}

return ret;
