How to download and decrypt HTTP Live Streaming (HLS) videos in iOS?
提问by NSPratik
I want to download M3U8 file chunks (HLS) and store that video (after decrypting it) for later viewing. I have made a demo to play M3U8 file but I want to download video data for later view.
我想下载 M3U8 文件块 (HLS) 并存储该视频（解密后）以供以后查看。我做了一个演示来播放 M3U8 文件，但我想下载视频数据供以后查看。

This Perl script is a good fetcher: https://github.com/osklil/hls-fetch
这个 Perl 脚本是一个很好的获取器：https: //github.com/osklil/hls-fetch
Steps:
脚步：
wget https://raw.githubusercontent.com/osklil/hls-fetch/master/hls-fetch
chmod +x hls_fetch
./hls_fetch --playlist "THE_URL"
Replace THE_URLwith the full URL of your M3U8 playlist (or try other options with --help).
替换THE_URL为 M3U8 播放列表的完整 URL（或尝试其他选项--help）。
Bonus: If you have missing Perl's JSON module (as I had), simply run sudo cpan JSON.
奖励：如果您缺少 Perl 的 JSON 模块（就像我一样），只需运行sudo cpan JSON.
