本文主要是介绍ffmpeg x264 x265 fdk-aac 编译记录，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ffmpeg 裁剪定制编译过多次了 这里记录下 主题部分

一 环境

ubuntu 18.04

ffmpeg:

v4.2.2 

ndk :android-ndk-r20b-linux-x86_64

fdk-aac 0.1.5

x264: 0.164.x 

1.1  下载编译fdk-aac 

 wget http://jaist.dl.sourceforge.net/project/opencore-amr/fdk-aac/fdk-aac-0.1.5.tar.gz

tar -xvf fdk-aac-0.15.tar.gz

 编写编译文件 

touch build_fdk_aac_clang_android.sh

#!/bin/bash
NDK=$ANDROID_NDK_HOME   # 这里需要替换成你本地的 NDK 路径，其他的不用修改
HOST_TAG=linux-x86_64

./configure \
