空间不足 啥情况啊

特别好！能够完全实现功能，学到很多！

尝试了很多次，从一开始下载opencv包时，就一直显示设备无足够空间，一直到最后运动监控的视频都无法生成

。。。。。

初识OpenCV

第一步安装open cv那里有问题，安装不了OpenCV， does not appear to contain CMakeLists.txt

学习

第一步安装open cv那里有问题，虽然通过了，但环境中报错，没有显示出face来

highgui error：v4lv4l2 vidioc_s_crop 发生这个错误怎么回事啊？

问一下，我在自己电脑上ubuntu 16.04下运行本课程代码，但是阈值显示不出来，怎么回事啊，而且运行test.mp4的时候和运行摄像头的时候都是处于静止的状态下就一直在记录，怎么回事啊？

课程里有完整代码

我想问一下这个一共有多少行代码呀？
