我们这里用到 ffmpeg
windows运行里输入cmd，打开dos，输入以下命令：
以一个mp4文件为例：zrg.mp4
先用ffmpeg把.mp4文件转换格式为.ts文件：
ffmpeg -y -i zrg.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb zrg.ts
这一步是把zrg.mp4转换成zrg.ts格式
再用ffmpeg把zrg.ts文件切片并生成playlist.m3u8文件，和5秒一个切片：
ffmpeg -i abc.ts -c copy -map 0 -f segment -segment_list playlist.m3u8 -segment_time 5 zrg%03d.ts
这样，就生成了。

Today, I went to the beach with my children. I found a sea
shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell
to her ear and screamed. There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is
completely off topic but I had to tell someone!
