rk3288安卓7.1,USB摄像头反复开关后出现问题

Question

我写了个脚本让它一直去点击相机在这个界面：

while true
do
input tap 800 500
    input keyevent 4
    input keyevent 4
done

之后过个十几二十分钟，界面返回到launcher3，也就是说相机他自动退出了：

此时串口输出错误信息

[ 2379.324670] init: Service 'cameraserver' (pid 29316) killed by signal 11
[ 2379.324722] init: Service 'cameraserver' (pid 29316) killing any children in process group

[ 2390.465591] uvcvideo: Failed to set UVC probe control : -110 (exp. 26).

能帮我看看是什么问题导致的吗

可能你的相机服务启动太频繁,然后被系统杀死了,所以就退出了(或者崩溃了)
