+自定义编译的主要目的是修改支持的格式, 因为默认包含了一些编解码器,解复用,协议等等, 这些格式可能你的项目用不到, 这时候可以修改 ffmpeg 的自定义编译选项, 以便于可以缩小库文件的体积, 以达到给 app 瘦身的目的
 
-[当前的编译规则文件](https://gitee.com/kikt/ijkplayer_thrid_party/blob/master/config/module.sh),如果你有自己的特定需求,可以修改编译选项,这个参考 [bilibili/ijkplayer](https://github.com/bilibili/ijkplayer) 或 [ffmpeg](http://ffmpeg.org/)
