mp4转码m3u8  
如果视频不为mp4格式，需先将视频转码为mp4，可使用如下命令进行转换  
ffmpeg -i 本地视频地址 -y -c:v libx264 -strict -2 转换视频.mp4  
将mp4格式转换为ts格式  
ffmpeg -y -i 本地视频.mp4 -vcodec copy -acodec copy -vbsf h264\_mp4toannexb 转换视频.ts  
将ts文件进行切片  
ffmpeg -i 本地视频.ts -c copy -map 0 -f segment -segment\_list 视频索引.m3u8 -segment\_time 5 前缀-%03d.ts
