环境 macOS 10.15.4 NDK 21.3.6528147 ffmpeg 4.2.3
1.执行sudo xcodebuild -license，防止编译的时候找不到一些文件报错
2.下载ffmpeg(4.2.3),解压后进入主目录，修改configure文件，找到
SLIBNAME_WITH_MAJOR=‘$(SLIBNAME).$(LIBMAJOR)‘ LIB_INSTALL_EXTRA_CMD=‘$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"‘ SLIB_INSTALL_NAME=‘$(SLIBNAME_WITH_VERSION)‘ SLIB_INSTALL_LINKS=‘$(SLIBNAME_WITH_MAJOR)$(SLIBNAME)‘
改为：
SLIBNAME_WITH_MAJOR=‘$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)‘ LIB_INSTALL_EXTRA_CMD=‘$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"‘ SLIB_INSTALL_NAME=‘$(SLIBNAME_WITH_MAJOR)‘ SLIB_INSTALL_LINKS=‘$(SLIBNAME)‘
3.下载NDK，我这里直接在Android Studio上下载，路径在~/Library/Android/sdk/ndk/21.3.6528147 ，将NDK路径加入path
编辑~/.bash_profile:
NDK_HOME=~/Library/Android/sdk/ndk/21.3.6528147 PATH=${PATH}:${NDK_HOME} export PATH export NDK_HOME
执行source ~/.bash_profile,使得路径实时生效
