ffmpeg下载m3u8流媒体

安装

编译好的windows可用版本的下载地址（官网中可以连接到这个网站，和官方网站保持同步）： http://ffmpeg.zeranoe.com/builds/

该版本为FFMPEG的Static，Static里面只有3个应用程序：ffmpeg.exe，ffplay.exe，ffprobe.exe，每个exe的体积都很大，相关的Dll已经被编译到exe里面去了。

使用

ffmpeg.exe

命令行进入bin目录，输入以下命令即可将m3u8下载为指定格式的文件

C:\01-python\59-ffmpeg\ffmpeg\bin\ffmpeg -i http://vodcdn.yst.vodjk.com/201909191433/2afc693f2edda43e677598144b12a31e/company/1/2019/8/1/18852t5bfe/sd/a84ccae0440549398f8080f6d336075b.m3u8 .\video\1416.mp4
