#EXT-X-ENDLISTm3u8视频另一种下载方式 如上图中用ts链接直接下载下来的ts视频文件是加密的（为什么要下加密的？虽然加密但是下载速度快啊）。
#EXT-X-KEY 字段已经写明了加密方式是AES-128，key通过URI获取，IV也有。
#EXT-X-KEY:
METHOD=AES-128,
URI="https://j-island.net/movie/hls_key/s/857401e309d8a032c3bb18f4b09b8db2/?f=jj_20190401_hihijets_004",
IV=0xaa3dcf6a7acb92ff4fb08d9b3b3d6f51那怎么解密呢？
1.复制URI地址到网页，你将秒速自动下载得到一个16字节文件 2.打开终端，打开该文件查看16进制：
打开二进制key
vi -b /路径/key文件输入“ :%!xxd”再把二进制文件切换到16进制
00000000: 283d cc2d 3747 e965 0a81 ead3 1e04 fa8a (=.-7G.e........
获取到key就是 283dcc2d3747e9650a81ead31e04fa8a 3.打开终端，转化
openssl aes-128-cbc -d -in /路径/media_0.ts -out /路径/media_decryptd_0.ts -nosalt -iv $iv -K $strkey*media_0.ts* : 加密ts文件（无法播放） *media_decryptd_0.ts* : 解密后ts文件（可以直接播放） *$iv* : aa3dcf6a7acb92ff4fb08d9b3b3d6f51（#EXT-X-KEY字段中获取，注意去掉0x） *$strkey* : 283dcc2d3747e9650a81ead31e04fa8a（上一步获得）
例子：
openssl aes-128-cbc -d -in /Users/用户名/Downloads/001.ts -out /Users/用户名/Downloads/001_dec.ts -nosalt -iv aa3dcf6a7acb92ff4fb08d9b3b3d6f51 -K 283dcc2d3747e9650a81ead31e04fa8a命令执行完秒速转化（也可能我文件特别短，都切成ts了，一般都不长吧…… 4.到对应路径下去，就能看到转化成功到ts视频了
