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。
https://twitter.com/n428dev/status/561814427150741505
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
video_tweet.json

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。
