标题: 不退出APP，初始化-退出，再初始化授权出现crash
目前需求是再不杀掉APP的情况下，能进行初始化-退出循环。
现在程序做法是按照MPU的初始化流程，完成初始化，然后同样按照MPU的退出流程，完成程序退出。
但是没有杀掉APP，然后再次走初始化的流程，发现授权出现崩溃，log如下，帮忙看下问题在什么地方。

log我在看。你试下第二次及其以后的初始化不要调用auth（）试试。

我把网络关掉就不会走授权的流程，是没有发生crash的，但是相机调用不起来。

auth外层有个网络判断，所以不会认证。相机调用我们没加网络限制的。你先试下调过一次认证之后就不要再调了。

cameraHolder里的onPreviewFrame看下有没有数据，先确定是没打开摄像头还是没渲染上。

第二次初始化完成进入videopreviewactivity，相机黑屏，没有渲染，cameraholder也没有数据，但是在这个时候切换一下摄像头，cameraholder有数据，但是没有渲染。

ANR是在二次推出的时候在BVPU.Finish();方法这里停止不走了

库内部的很多资源释放依赖于system.exit(0)，如果不退出直接重新初始化会出现很多资源冲突和异常，目前不支持不退出情况下的反复初始化

好，那我们看下不初始化实现功能吧。
另外问下，videopreviewactivity的surfaceview打开前置摄像头的时候，显示结果有左右镜像的情况，如何才能不再镜像？

如图，左右实际上显示是反的，有镜像，设备自带的相机前置是没有镜像效果的。

如果把摄像头固定，屏幕旋转180度来看，你会发现画面是对的（原理同后置摄像头），因为自拍的需要，所以拍照软件都会做一个镜面渲染处理，使得画面跟照镜子一样。实际上，未经处理的系统输出的数据码流就是你现在看到的画面，跟网传画面和录像画面都是一致的，如果做了镜面处理，那么出来的OSD效果就像是镜子中看到的字一样，都是镜像反过来的效果，跟网传和录像都不一致。
