原理： 下载视频轨道文件、和音频轨道文件，最后用ffmpeg进行视频轨和音轨的合成
目前下载工具可以在 win/linux/mac上运行。其实就是执行python
Linux/Mac OS X
在linux/Mac OS X系统中可能需要修改下文件权限
Linux
cd /path/to/BiliDown
chmod +x tools/linux/ffmpeg
Mac
cd /path/to/BiliDown
chmod +x tools/mac/ffmpeg
教程
pip install -r reqirements.txt
编辑 download.py 文件，在最后 url 中填上你需要下载的B站链接，
如果需要换 cookie, 在Cookies中填写你浏览器中的cookie内容
最后用python执行就行了
最终需要的视频会在当前目录下的 Output 中生成
