一、关于m3u8：
m3u8是苹果公司推出一种视频播放标准，是m3u的一种，不过编码方式是utf-8，是一种文件检索格式，将视频切割成一小段一小段的ts格式的视频文件，然后存在服务器中（现在为了减少I/o访问次数，一般存在服务器的内存中），通过m3u8解析出来路径，然后去请求。
示例：
#EXTM3U #EXT-X-TARGETDURATION:10 #EXTINF:9, http://data.video.iqiyi.com/videos/vts/20210301/69/b8/73ad4ef04fde4586ef2799ecd67241ce.ts"text-align: center">
我们想要的mp4文件就是一个个ts文件按照顺序拼接成的，废话不多说直接上代码。
