### トラブルシューティング
ずっとこれが出てたんだが、何かなと思ってたら
$ node get-mp4.js
(node:137900) UnhandledPromiseRejectionWarning: ResourceNotFoundException: No fragments found in the stream for the clip request.
jsでtimestampを作るとき、monthは -1なのね。
new Date(2021, 10, 13, 23, 40, 30); // 2021/11/13 23:40:30
new Date(2021, 11, 13, 23, 40, 30) でやってたから、No fragments foundだった。。あほやわ
よっしゃあああああああああああああああああああ
