HLS合成为一整个视频拓展篇
M3U8视频下载完成之后, 会有一个索引文件加上N多个分片文件, 这样我们想拷贝整个M3U8文件就会很麻烦, 而且M3U8索引文件中会定义分片文件的位置, 如果是相对地址还好, 如果是绝对地址那拷贝出来也不能用.
我们能不能将分散的M3U8分片文件合成一整个MP4文件, 这样我也可以拷贝, 也可以分享.
具体的做法可以参考：M3U8-TS文件合并为MP4文件, 我这儿就不赘述了, 这儿主要分享一下合并过程中出现的一些坑, 希望对大家解决问题有帮助.

1.加密的M3U8视频如何合并
举一个加密视频的例子: https://europe.olemovienews.com/hlstimeofffmp4/20210226/fICqcpqr/mp4/fICqcpqr.mp4/master.m3u8
