安裝ffmpeg
因涉及到格式轉(zhuǎn)換，所以需要同時(shí)安裝ffmpeg。
手動(dòng)編譯安裝ffmpeg，可參考：http://www.itdecent.cn/p/99738fb16e66
如果是Mac的話，可以使用brew安裝ffmpeg：
$ brew install ffmpeg
查看可用格式
$ youtube-dl -F https://www.youtube.com/watch?v=y83x7MgzWOA
指定代理
$ youtube-dl --proxy socks5://127.0.0.1:1086 -F https://www.youtube.com/watch?v=y83x7MgzWOA
