$ git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
//进入ijkplayer-ios
$ cd ijkplayer-ios
//切换分支
$ git checkout -B latest k0.8.8
开启支持RTSP,默认不支持RTSP,需要修改module-lite.sh内容,新增对应的协议,module-lite.sh是在config目录下
//目录：~/config/module-lite.sh 将这一行：
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --disable-protocol=rtp"
//修改为：
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
//新加：
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=rtsp"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=tcp"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-decoder=mjpeg"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=mjpeg"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-openssl"
然后修改支持module-lite.sh
//进入ijkplayer/config 目录
$ cd config
//移除module.sh文件
$ rm module.sh
//替换模块
$ ln -s module-lite.sh module.sh

若遇到问题
问题1：
AS libavcodec/arm/aacpsdsp_neon.o
./libavutil/arm/asm.S:50:9: error: unknown directive
.arch armv7-a
^
make: *** [libavcodec/arm/aacpsdsp_neon.o] Error 1
make: *** Waiting for unfinished jobs....
原因：Xcode 已经弱化了对 32 位的支持
解决办法：
~/ios/compile-ffmpeg.sh 删掉armv7
//24行改为：
FF_ALL_ARCHS_IOS8_SDK="arm64 i386 x86_64"
//120行改为：
if [ "$FF_TARGET" = "armv7s" -o "$FF_TARGET" = "arm64" ]; then
//159行改为：
echo " compile-ffmpeg.sh arm64|i386|x86_64"
问题2：
ERROR: openssl not found
此问题报错处来源于~/extra/ffmpeg/configure
enabled openssl && { use_pkg_config openssl openssl openssl/ssl.h OPENSSL_init_ssl ||
use_pkg_config openssl openssl openssl/ssl.h SSL_library_init ||

check_lib openssl openssl/ssl.h SSL_library_init -lssl -lcrypto -lws2_32 -lgdi32 ||
die "ERROR: openssl not found"; }
修改为：
enabled openssl && { use_pkg_config openssl openssl openssl/ssl.h OPENSSL_init_ssl ||
check_lib openssl openssl/ssl.h OPENSSL_init_ssl -lssl -lcrypto ||
use_pkg_config openssl openssl openssl/ssl.h SSL_library_init ||

check_lib openssl openssl/ssl.h SSL_library_init -lssl -lcrypto -lws2_32 -lgdi32 ||
die "ERROR: openssl not found"; }
若依旧报错，检查mac是否安装了openssl
$ brew install openssl
注：编译失败，修改后重新编译需按照步骤clean ffmpeg、编译openssl、编译ffmpeg重新编译；之前编译ffmpeg失败后，修改后clean，再编译，一直报错ERROR: openssl not found，中间未进行openssl编译
6,打包IJKMediaFramework ~/ios/IJKMediaPlayer/IJKMediaPlayer.xcodeproj选择IJKMediaFrameworkBuild Phases->Link Binary With Libraries添加libcrypto.a 和 libssl.a 文件,这两个文件在~/ios/build/universal/lib下Edit Scheme…->Run->Build Configuration 选择releaseXcode->Preferences->Locations
跳转至DerivedData处
编译真机下framework，Build Setting->Architectures,改为arm64,选择真机，command+B
Build成功后，在上步的DerivedData内则有刚编译成功的项目文件夹，~/Build/Products内则出现Release-iphoneos
编译模拟器下framework，Build Setting->Architectures,改为x86_64,选择模拟器，command+B
Build成功后，~/Build/Products内则出现Release-iphonesimulator
cd 至 Products下，合并真机与模拟器版本
lipo -create Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework -output IJKMediaFramework
用合并后的新的IJKMediaFramework，替换掉~/Release-iphoneos/IJKMediaFramework.framework内的IJKMediaFramework
~/Release-iphoneos下的IJKMediaFramework.framework即为最终的framework
工程内导入IJKMediaFramework.framework
