扩展库支持（External library support）

ffmpeg提供的一些功能是由其他扩展库支持的，如果需要使用需要明确声明，确定编译的第三方库的目标架构--arch相同就好了，在编译ffmpeg的时候需加入第三方库的头文和库搜索路径（通过extra-cflags和extra-ldflags指定即可），剩下的事ffmpeg都给你做好了。

工具链选项（Toolchain options）

ffmpeg代码本身是支持跨平台的，要编译不同的平台需要配置不同平台的交叉编译工具链。ffmpeg都是c代码，所以不需要配置c++的sysroot。常用的就几个arch,cpu,cross-prefix,enable-cross-compile,sysroot,target-os,extra-cflags,extra-ldflags,enable-pic。现在Android和IOS几乎没有armv5的设备了，所以如果编译这两个平台配置armv7和armv8就好了。
