我拿罗技C310插上Fireprime (使用FirePrime_Android5.1_201603030926固件)

结果预览画面全部绿色

uart不断打印

换另外一台USB摄像头
可以正常预览但是不能拍照
一按拍照就出现下面的错误讯息

04-18 14:40:24.675: E/ion(156): ioctl c0144900 failed with code -1: Operation not permitted

04-18 14:40:24.676: E/CameraHal(156): captureEncProcessPicture(1120): mJpegBufferProvider->createBuffer FAILED

之后摄像头APP就挂掉了
然后要重开机才可以再连接到

到现在找不到一台可以正常预览拍照的USB摄像头
有人有遇过这情形吗??

回退提交3b8d8e5。
git revert 3b8d8e5
再重新编译一下摄像头代码
