youtube-dl -F {video_link}
#查看該視頻支持的高清格式，最高 4k 解析度
youtube-dl -cvt -f 140+137 --write-auto-sub --simulation {video_link}
#依據上條命令回顯，適當調整 -f 後的 argument，這裡有個小 trick 就是該參數可以是 audio+video flag，兩者均下載完畢 youtube 會調用 ffmepg 或另一開源實現來合併音視頻 stream。
BTW，手動合並也就幾行 ffmepg 命令嘛，非 CLI 同好的話，可以用 bash 包裝下，一勞永逸。
另附多源下載方案：

The goal of this book is not to teach solutions to specific problems, but rather to teach you how to think regular expressions so that you will be able to conquer whatever problem you may face. 😉

Hello,

Paypal disabled Union Pay cards for our account as they are currently having difficulties (which Paypal is currently trying to solve). Once the problem is solved we will be able to resume taking payments from Union Pay.

Thank you.

遇上與樓主同樣的問題了，也納悶上週不才用 Union Pay 成功續付了 DO 的 Droplet。
以上是搬瓦工的工單回复，今早諮詢 Paypal 時，客服也說正著手解決，一起靜候佳音吧。
