如何通过单独提供密钥文件来播放 m3u8 加密播放

问题描述

我有一个 m3u8 播放列表文件(我们称之为prime)，它指向另一个播放列表文件，该文件又包含带有密钥文件URL 的ts URL.使用 MPMoviePlayer 我目前可以播放 prime m3u8 文件.这些片段是 encrypted 使用 AES-128 位加密，密钥文件在最终的 m3u8 文件中.有没有办法可以提供最终的 m3u8 文件并告诉应用程序使用本地密钥文件来解密视频，这样我就不必公开发布密钥文件.

I have a m3u8 playlist file(lets call it prime), which points to another playlist file which in turn has the ts URLs with the key file URL. Using MPMoviePlayer I can currently play the prime m3u8 file. The segments are encrypted with AES-128 bit encryption and the key file is in the final m3u8 file. Is there a way that I can supply the final m3u8 file and tell the app to use a local key file to decrypt the video, so I don't have to publish the key file publicly.

推荐答案

是的 -- 您可以在将最终的 m3u8 文件传递​​给播放器之前对其进行修改.例如，将 KEY 行更改为引用 http://localhost/key.然后你会想要运行一个本地 http 服务器，比如 cocoahttpserver 来将密钥传递给视频播放器.

Yes -- You can modify the final m3u8 file before passing it to the player. For example, change the KEY lines to refer to http://localhost/key. Then you would want to run a local http server such as cocoahttpserver to deliver the key to the video player.
