Anaconda python 3.5
Opencv 3
pyprind 2
Ubuntu 16.04
wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-5.2.0-Linux-x86_64.sh
下载完毕后,开始安装
bash Anaconda*.sh # *号直接匹配
出现如上画面,接下来不停地按回车,直到出现这个画面:
我们输入“yes”
变成这样,此时回车(按一遍就行)
到这里可能会卡一下,接下来就是安装步骤:
询问你是否添加到环境变量,输入“yes”,回车
安装完毕,但是接下来再回车会问你是否安装VS Code,根据需要吧,在这里我们选择 no (一定要自己手打,回车是默认yes)
再回车就行了。
sudo pip3 install opencv-python
如果提示不存在,输入下面代码安装
sudo pip insatll pip3
创建py文件
sudo vim CLIPlayVideo.py
在其中添加以下代码

上传一个视频到当前文件夹中,如果你也在使用Xshell,那你也可以用Xftp
效果如下,接下来开始转换
python3 CLIPlayVideo.py BadApple.mp4 -e
如果已经转换过,下次播放可以直接
python3 CLIPlayVideo.py charvideo.txt
接下来就是等待他转换
完成后播放,也可以用上面的播放命令
