FFmpeg、x264以及fdk-aac 编译整合

接上文 FFMPEG 编译流程(极客版)

编译 fdk-aac

libfdk-aac version:0.1.5

下载

运行

# 修改 build_fdk_aac_clang.sh 可执行权限
chmod +x build_fdk_aac_clang.sh
# 运行编译脚本
bash build_fdk_aac_clang.sh

编译 x264

x264

wget https://code.videolan.org/videolan/x264/-/archive/master/x264-master.tar.bz2

解压

编译警告

Android NDK 缺少arm-linux-androideabi-pkg-config


AS编译失败
undefined reference to 'atof'
参考：
【Android FFMPEG 开发】Android Studio 中 配置 FFMPEG 库最小兼容版本 ( undefined reference to ‘atof’ )
