在MacOS上编译ExoPlayer的FFmpeg扩展

1.git源码

git clone https://github.com/google/ExoPlayer.git
2.下载好NDK r15c

下载地址：https://dl.google.com/android/repository/android-ndk-r15c-darwin-x86_64.zip

3.写脚本
EXOPLAYER_ROOT="$(pwd)"
FFMPEG_EXT_PATH="${EXOPLAYER_ROOT}/extensions/ffmpeg/src/main"
HOST_PLATFORM="darwin-x86_64"
NDK_PATH=/Users/nlj/android-ndk-r15c   #这里填你解压出来的地址

写好了请把它放到源码根目录

别问，问就是不知道！！！略略略

好吧瞎说的

第一步： 取编译好的so文件

‎⁨MacOS10.14.5⁩ ▸ ⁨用户⁩ ▸ ⁨nlj⁩ ▸ ⁨ExoPlayer⁩ ▸ ⁨extensions⁩ ▸ ⁨ffmpeg⁩ ▸ ⁨src⁩ ▸ ⁨main⁩

这个目录下有个文件夹叫libs  里面有不同架构的so文件 （不懂的去百度）

第二步：取Java文件

还是这个目录下有个java文件夹，点到底里面有4个类

把它放到这里
