执行脚本：

# 1. 添加权限
chmod a+x build_android.sh
# 2. 执行脚本
./build_android.sh

3. 编译结果

4. 遇到的问题

1.编译x86-64时遇到 C compiler test failed

原因：

# 查看编译日志
vim ffbuild/config.log

2. 编译x86时遇到如下问题：

解决方法：
编译配置添加如下内容，取消汇编优化

--disable-asm \
--disable-yasm \

5. 参考

1. Unbuntu环境编译 Android平台可用ffmpeg（带三方库fdk-aac和lame）
2. 利用NDK(r20) 编译FFmpeg 4.2.1 Android版本
3. nkd 编译ffmpeg错误: clang is unable to create an executable file. C compiler test failed.
4. Clang编译Android平台能用的FFmpeg可执行程序
5. ffmpeg4.4在Linux下使用android NDK 21新版本编译及其问题解决
6. FFmpeg、x264以及fdk-aac 编译整合
