分析过程：

01-02 00:09:09.954 F/DEBUG   ( 3853):     #00 pc 00013672  /system/lib/libuvc_meig_camera.so (_ZN7qcamera6Camera18makeCapabilitySizeEiPN7android6VectorINS_15cam_dimension_tEEE+121)

第一步：

上述行，可以知道是libuvc_meig_camera.so 报错了。
第二：
cd out/target/product/msm8953_64/symbols/system/lib/
addr2line -f -e libuvc_meig_camera.so 00013672

然后从上面可以知道是
hardware/qcom/camera/QCamera2/uvccamera/src/Camera.cpp:1272
这个地方出现异常了，需要修改
