设置VI设备属性参数错误问题

按照SDK的例子，代码如下：
HI_S32 s32Ret;
VI_DEV ViDev = 0;
VI_CHN ViChn = 0;
VI_DEV_ATTR_S stDevAttr;
VI_CHN_ATTR_S stChnAttr;
stDevAttr.enIntfMode = VI_MODE_BT656;
stDevAttr.enWorkMode = VI_WORK_MODE_1Multiplex;
stDevAttr.au32CompMask[0] = 0xFF000000;
stDevAttr.au32CompMask[1] = 0x0;
stDevAttr.enScanMode = VI_SCAN_INTERLACED;
stDevAttr.s32AdChnId[0] = -1;
stDevAttr.s32AdChnId[1] = -1;
stDevAttr.s32AdChnId[2] = -1;
stDevAttr.s32AdChnId[3] = -1;
s32Ret = HI_MPI_VI_SetDevAttr(ViDev, &stDevAttr);
if (s32Ret != HI_SUCCESS)
{
printf("Set dev attributes failed with error code %#x!\n", s32Ret);
return HI_FAILURE;
}


结果报错Set dev attributes failed with error code 0xa0108003!

查了一下错误代码
0xA0108003 HI_ERR_VI_INVALID_PARA 视频输入参数设置无效
请问如何设置参数，我只想用1路D1的，型号HI3520D
