sample_venc录制的视频是绿色的为什么呢？

我用的模组是ov9712，不管白天还是晚上录制都是绿色的。硬件没有问题，我用过别人的系统程序测试过是正常图像的。
使用Hi3518E_SDK_V1.0.4.0/mpp/sample/sample_venc里的例子，录制的视频是绿色的为什么呢？
我修改Hi3518E_SDK_V1.0.4.0/mpp/component/isp/sensor/ov9712_sensor_ctl.c里的void sensor_linear_720p25_init()函数，把0x12，的值改成0x02，重新编译后，录制的视频没有显示彩条呀，说明没有配置镜头呀，怎么配置呢？




这个是安装驱动时的打印信息
