一、新版本Camx

debug 指令：

adb shell setprop vendor.camera.aedebug.enable 1 // 开启曝光锁定
adb shell setprop vendor.camera.debugTime 33000000 // 曝光ns
adb shell setprop vendor.camera.debugGain 10 // gain

二、旧版本 Camx 手动设置曝光/gain时间

debug 指令：

adb shell setporp vendor.debug.camera.aec.manual  TRUE // 开启
adb shell setporp vendor.debug.camera.aec.ctrl.expTime  // 曝光ns
adb shell setporp vendor.debug.camera.aec.ctrl.gain // gain

代码路径：camx\src\settings\common\camxsettings.xml

aec相关信息打印：
