android - 无法为 ExoPlayer 构建 ffmpeg
问题描述
我正在尝试在我的应用程序中添加对多种音频格式的支持，但似乎无法在我的 Mac 上构建 ffmpeg 扩展。
我遵循了这个自述文件：https ://github.com/google/ExoPlayer/tree/dev-v2/extensions/ffmpeg
但我不断收到此错误：
</Users/mac/NDKK>/toolchains/llvm/prebuilt/darwin-x86_64/bin/armv7a-linux-androideabi16-clang is unable to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
我尝试了 NDK20 和 NDK19 但同样的错误，所以需要熟悉这个的人的帮助。
我正在尝试构建以下格式“aac ac3 eac3 dca”。
编辑：这是完整的命令和日志：

解决方案
你应该使用 NDK r15c，它有 gcc/nm/strip 工具链。
您可以参考以下页面。
https://blog.csdn.net/King1425/article/details/90410625
我可以使用页面中描述的方法编译确定，如下所示。
