大佬，请问工程编译后在联想小新PAD上摄像头识别正常，但是换到联想K10pad上预览出现花屏

[orchidinvalley]

在联想K10pad上预览黑屏，修改了配置参数，采用最低分辨率，默认UVC_VS_FRAME_UNCOMPRESSED，预览有画面了，显示上半部绿屏，下半部分条纹状图像，请问什么原因，
下面是K10 运行的日志信息

我对比了 正常pad和故障pad的打印信息，有两个可疑的错误，不知道是不是这个原因导致的预览有问题。
1、E/FBI: Can't load library: dlopen failed: library "libmagtsync.so" not found
我在工程里面没找到这个SO库，不知道是不是系统的问题
2、D/BufferQueueConsumer: SurfaceTexture-1-31443-0 disconnect
能正常预览的pad 没有这个日志打印。

这个问题有解决吗
