ffmpeg windows 32位编译
编译方式
自动编译工具套件 -- https://github.com/m-ab-s/media-autobuild_suite
github克隆完成后，双击bat文件打开编译窗口，注意git检出的目录需要简短，最好选一个盘的根目录。
选择编译版本（按需选择编译，按照客户端程序需求来，如果兼容win7就编译32位就够用了）
按需选择编译三方库
在选择结束后会提示总的配置的文件在哪个位置，如下我的在 E:\media-autobuild_suite\build\ffmpeg_options.txt
打开这个文件优化一下内容，如果是转码的用途可以参考我的这个配置文件（ffmpeg_options.txt）
