1：下载ijkplayer包 https://github.com/Bilibili/ijkplayer。
2：解压 ijkplayer-master， cd 到ijkplayer-master文件夹，执行init-ios.sh，等待下载ffmpeg结束。
3.在 ios/compile-ffmpeg.sh 中将FF_ALL_ARCHS_IOS8_SDK="armv7 i386 x86_64"
修改为：FF_ALL_ARCHS_IOS8_SDK="arm64 i386 x86_64"
4.在 ijkplayer-master 下的 config 中，打开 module-lite.sh
将 export COMMON_FF_CFG_FLAGS="COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
并添加 export COMMON_FF_CFG_FLAGS="COMMON_FF_CFG_FLAGS --enable-decoder=mjpeg"
export COMMON_FF_CFG_FLAGS="”被简书转义了，老铁们看下图自己补充。

5.cd 到ijkplayer-master文件夹下的ios文件夹执行： ./compile-ffmpeg.sh clean 和 ./compile-ffmpeg.sh all。
6.运行ios/IJKMediaPlayer.会在，"config.h" 中 "armv7/config.h"
