Heroku上的視頻問題

我最近在Heroku平臺上移動了我的RoR應用程序，幾乎所有的都能正常工作，除了視頻。當我的應用程序在本地運行但不在heroku上時，它工作正常。這是錯誤日誌中我得到，如果有人知道它可以從未來：Heroku上的視頻問題

您必須提供更多信息。你如何提供視頻？ –

好了，現在他們已經與項目一起部署了（它們在readonly-fs上）。但它應該工作，因爲常規圖片以相同方式呈現。 – Roch

它看起來像你必須試圖做一些事情寫入東西，有做與Heroku文件系統上的視頻進行比較。這是行不通的，因爲它是隻讀的。

您需要存儲您的視頻以及當前在其他地方的文件系統上創建的任何其他內容（Amazon S3工作良好）。
