耗时一个多星期终于基于这个版本一通修改编译出来了。目前主要是编译的Android arm64的。

[arm64-v8a] Compile : ijkj4a <= j4a_base.c [arm64-v8a] Compile : ijkj4a <= AudioTrack.c [arm64-v8a] Compile : ijkj4a <= MediaCodec.c [arm64-v8a] Compile : ijkj4a <= PlaybackParams.c [arm64-v8a] Compile : ijkj4a <= MediaFormat.c [arm64-v8a] Compile : ijkj4a <= Build.c [arm64-v8a] Compile : ijkj4a <= Buffer.c [arm64-v8a] Compile : ijkj4a <= ByteBuffer.c [arm64-v8a] Compile : ijkj4a <= Bundle.c [arm64-v8a] Compile : ijkj4a <= ArrayList.c [arm64-v8a] Compile : ijkj4a <= IMediaDataSource.c [arm64-v8a] Compile : ijkj4a <= IAndroidIO.c [arm64-v8a] Compile : ijkj4a <= AudioTrack.util.c [arm64-v8a] Compile : ijkj4a <= ByteBuffer.util.c [arm64-v8a] Compile : android-ndk-profiler <= prof.c [arm64-v8a] Compile : ijkj4a <= IjkMediaPlayer.c [arm64-v8a] Compile++ : ijksoundtouch <= AAFilter.cpp [arm64-v8a] Compile++ : ijksoundtouch <= FIFOSampleBuffer.cpp [arm64-v8a] Compile++ : ijksoundtouch <= cpu_detect_x86.cpp [arm64-v8a] Compile++ : ijksoundtouch <= sse_optimized.cpp [arm64-v8a] Compile++ : ijksoundtouch <= FIRFilter.cpp [arm64-v8a] Compile++ : ijksoundtouch <= RateTransposer.cpp [arm64-v8a] Compile++ : ijksoundtouch <= InterpolateCubic.cpp [arm64-v8a] Compile++ : ijksoundtouch <= InterpolateShannon.cpp [arm64-v8a] Compile++ : ijksoundtouch <= InterpolateLinear.cpp [arm64-v8a] Compile++ : ijksoundtouch <= BPMDetect.cpp [arm64-v8a] Compile++ : ijksoundtouch <= TDStretch.cpp /home/cp/androidsoft/mijkplayer/android/ijkplayer/ijkplayer-arm64/src/main/jni/ijkmedia/ijksoundtouch/source/SoundTouch/TDStretch.cpp:66:13: warning: unused variable '_scanOffsets' [-Wunused-const-variable] const short _scanOffsets[5][24]={ ^ 1 warning generated. [arm64-v8a] Compile++ : ijksoundtouch <= PeakFinder.cpp [arm64-v8a] Compile++ : ijksoundtouch <= mmx_optimized.cpp [arm64-v8a] Compile++ : ijksoundtouch <= SoundTouch.cpp [arm64-v8a] StaticLibrary : libcpufeatures.a [arm64-v8a] StaticLibrary : libyuv_static.a [arm64-v8a] Compile++ : ijksoundtouch <= ijksoundtouch_wrap.cpp [arm64-v8a] StaticLibrary : libijkj4a.a [arm64-v8a] StaticLibrary : libijksoundtouch.a [arm64-v8a] StaticLibrary : libandroid-ndk-profiler.a [arm64-v8a] SharedLibrary : libijksdl.so [arm64-v8a] Install : libijksdl.so => libs/arm64-v8a/libijksdl.so [arm64-v8a] SharedLibrary : libijkplayer.so [arm64-v8a] Install : libijkplayer.so => libs/arm64-v8a/libijkplayer.so /home/cp/androidsoft/mijkplayer/android

1.升级了opennssl：

IJK_OPENSSL_COMMIT=OpenSSL_1_1_1w

2.ndk使用ndk21，会报找不到xxx-ar、xxx-runlib等ndk'编译脚本找不到，直接去ndk目录找对应的llvm脚本复制改文件名即可；也可以使用更高的版本，但是高版本llvm编译，需要大量修改编译脚本，本着能编译将就使用原则，没去尝试；

3.ijkplayer在sh compile-ijk.sh arm64 编译时会报错，ijkplayer里面的c代码和makefile都需要修改：

3.1其中一个注册协议解析的报错需要修改 ffmpeg6.1的源代码，参照这个 https://github.com/bilibili/ijkplayer/issues/3350；

3.2 ffmpeg6.1 接口有一些变更，需要同步修改 android\ijkplayer\ijkplayer-arm64\src\main\jni 源代码；

3.3 APP_STL := stlport_static 高版本ndk已废弃，需要修改APP_STL := c++_static；

3.4 在 mijkplayer/android/ijkplayer/ijkplayer-arm64/src/main/jni/ijkmedia/ijkplayer目录下的makefile文件的这个标记不能使用： LOCAL_CFLAGS += -std=c99；会报 error: invalid argument '-std=c99' not allowed with 'C++' 错误，因为mijkplayer/android/ijkplayer/ijkplayer-arm64/src/main/jni/ijkmedia/ijkplayer/ijkavutil/ijkstl.cpp 这个是c++语法文件，若有c99标记，编译器编译时无法兼容成c的语法。

3.5 在编译Android arm64的 ffmpeg时会报一个 ff_tx_codelet_list_float_x86 undefined的错误，这个应该是需要屏蔽不同abi耦合的，没有细究，不清楚ffmpeg编译为啥会出这问题，我的做法简单粗暴，直接在对应的源文件里添加一个对空函数体的对应函数名；

4.参照https://github.com/1976222027/mijkplayer.git 项目作者的共享版本以及https://github.com/ShikinChen/ijkplayer-android 作者的静态库版本修改适配的ffmpeg6.1。

虽然ijk官方好久没更新了，希望大家群策群力，相互帮助，把ijk盘起来！若有需要，可以站内联系，或者建一个维护群。 另外，上面几楼的问题，在这里统一答复一下：修改ffmpeg的配置后，需要删除对应的abi目录下的config.h,这个就是根据脚本配置文件动态生成的控制ffmpeg里面相关所有子功能的c代码配置文件，每次改配置脚本需要重新生成；

Before Build

# install homebrew, git, yasm
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install git
brew install yasm

# add these lines to your ~/.bash_profile or ~/.profile
# export ANDROID_SDK=<your sdk path>
# export ANDROID_NDK=<your ndk path>

# on Cygwin (unmaintained)
# install git, make, yasm

• If you prefer more codec/format

cd config
rm module.sh
ln -s module-default.sh module.sh
cd android/contrib
# cd ios
sh compile-ffmpeg.sh clean

• If you prefer less codec/format for smaller binary size (include hevc function)

cd config
# 删除默认的解码器
rm module.sh
# 创建一个软连接指向 module-lite-hevc.sh，这个可根据自己需求进行选择
ln -s module-lite-hevc.sh module.sh
cd android/contrib
# cd ios
sh compile-ffmpeg.sh clean

• If you prefer less codec/format for smaller binary size (by default)

cd config
rm module.sh
ln -s module-lite.sh module.sh
cd android/contrib
# cd ios
sh compile-ffmpeg.sh clean

• For Ubuntu/Debian users.

# choose [No] to use bash
sudo dpkg-reconfigure dash

Commercial Use

ijkplayer is licensed under LGPLv2.1 or later, so itself is free for commercial use under LGPLv2.1 or later

But ijkplayer is also based on other different projects under various licenses, which I have no idea whether they are compatible to each other or to your product.

IANAL, you should always ask your lawyer for these stuffs before use it in your product.
