下载和播放离线HLS内容-iOS 10 [英] Downloading and playing offline HLS Content - iOS 10

问题描述

从iOS 10开始，Apple提供了下载HLS(m3u8)视频以供离线查看的支持.

Since iOS 10, Apple has provided the support for downloading HLS (m3u8) video for offline viewing.

我的问题是:是否只有在播放HLS时才可以下载HLS?或者，我们只在用户按下下载按钮并显示进度时才下载.

My question is: Is it necessary that we can only download HLS when it is being played ? Or we can just download when user press download button and show progress.

有人在Objective C版本中实现了此功能吗?实际上，我以前的应用程序是在Objective C中制作的.现在，我想增加对下载HLS而不是MP4的支持(以前我是为了离线查看而下载MP4).

Does anyone has implemented this in Objective C version? Actually my previous App is made in Objective C. Now I want to add support for downloading HLS rather than MP4 (previously I was downloading MP4 for offline view).

我真的很绝望.请分享想法或任何实施的代码.

I am really desperate to this. Please share thoughts or any code if implemented.

推荐答案

唯一的方法是设置HTTP服务器，以在下载文件后在本地提供文件.

The only way you can do this is to set up an HTTP server to serve the files locally after you've downloaded them.

实时播放列表使用滑动窗口.您需要在目标持续时间之后定期重新加载它，并仅下载列表中显示的新段(稍后将其删除).

The Live playlist uses a sliding-window. You need to periodically reload it after target-duration time and download only the new segments as they appear in the list (they will be removed at a later time).
