可能错误
-D WITH_NVCUVID=ON是打开libnvcuvid模块的功能，但由于cuda预置的nvidia版本和自己pc安装nvidia版本有差异，所以需要修改~/NVIDIA_CUDA_8.0/Samples/findglib.mk文件，将UBUNTU_PKG_NAME = 'nvidia-367'修改为自己机器中的nvidia驱动版本。同时，还建立软链接：
sudo ln -s /usr/lib/nvidia-378/libnvcuvid.so /usr/lib/libnvcuvid.so
sudo ln -s /usr/lib/nvidia-378/libnvcuvid.so.1 /usr/lib/libnvcuvid.so.1
