- Windows下安装ffmpeg：
1.FFmpeg下载：http://ffmpeg.zeranoe.com/builds/
2.下载并解压FFmpeg文件夹，它会生成一个类似名为“ffmpeg-20170605-4705edb-win64-static.zip”的新文件夹，解压到d盘。
3.配置FFmpeg环境变量：
点击“开始菜单”，再点击“控制面板”，再点击“系统”，然后点击“高级系统设置”，跳出“系统属性”窗口后，最后点击“环境变量”按钮，在“Path”变量原有变量值内容上加上“;d:\ffmpeg\bin”：（如下图所示）
4.打开命令提示符窗口（cmd）。输入命令“ffmpeg –version”。如果命令提示窗口返回FFmpeg的版本信息（如下图所示），那么就说明安装成功了，你可以在命令提示行中任意文件夹下运行FFmpeg。
