Twitterの動画投稿機能(video.twimg.com)で投稿した動画のURLをJSONから取得できるようになりました

More than 5 years have passed since last update.

1月にTwitterの公式アプリから動画(30秒まで)がアップロードできるようになりました。

2月からTwitter公式で開発者向けにビデオのURLをツイートのJSONから取得できるようになるというアナウンスがありましたが、私が試したところ2月7日にはビデオ情報がツイートのJSONに格納され返却されるようになっていました。

これをTwitterクライアントで生のJSONで取得すると以下になります

JSONの階層的に extended_entities -> media -> video_info

に動画情報が格納されています。
Youtubeのように各種のビットレート、各種の動画フォーマットにエンコードされた動画ファイルのURLが用意されています・

各種言語のTwitterのクライアントライブラリが対応するまではこのJSONを元に自前でゴリゴリパーサーを書くか、各種言語のライブラリを書き換えちゃいましょう。
