树莓派4B硬解码编译安装FFMPEG与X264过程

一、环境介绍

开发板：树莓派4B

二、编译安装X264

下面一切都在树莓派4B上操作，下面步骤里下载各种安装包之后(下载通过树莓派4B自带的谷歌浏览器下载)，再将安装包移动到U盘里进行编译的，主要是树莓派4B本身空间不大。

工作路径:/home/pi/source

2.1 编译安装NASM

下载NASM库:  http://distfiles.macports.org/nasm/

$wget http://distfiles.macports.org/nasm/nasm-2.15.05.tar.bz2
$tar xvf nasm-2.15.05.tar.bz2
$cd nasm-2.15.05
$./configure
$make && sudo make install

2.2 下载编译SDL2

下载地址: https://www.libsdl.org/download-2.0.php

$wget https://www.libsdl.org/release/SDL2-2.0.16.tar.gz
$tar xvf SDL2-2.0.16.tar.gz
$cd SDL2-2.0.16
$./configure --prefix=$PWD/_install
$make && make install
$sudo cp _install/include /usr/ -rf
$sudo cp _install/lib /usr/ -rf

2.3 下载编译X264

下载地址: https://www.videolan.org/developers/x264.html

$wget https://code.videolan.org/videolan/x264/-/archive/master/x264-master.tar.bz2
$tar xvf x264-master.tar.bz2
$cd x264-master
$./configure --prefix=$PWD/_install --enable-shared
$make && make install
$sudo cp _install/include /usr/ -rf
$sudo cp _install/lib /usr/ -rf

2.4 下载编译FFMPEG库

下载地址:  http://www.ffmpeg.org/download.html

$wget http://www.ffmpeg.org/releases/ffmpeg-4.4.tar.bz2
$tar xvf ffmpeg-4.4.tar.bz2
$cd ffmpeg-4.4
$sudo apt-get install libomxil-bellagio-dev
$sudo apt-get install libasound2-dev
保存以下内容为config_ffmpeg.sh, chmod +x ./config_ffmpeg.sh, ./config_ffmpeg.sh运行

2.4 将库集合到一个目录下，方便后续编译调用，指定路径

$mkdir ffmpeg_x264_SDL2_lib
$cp /home/pi/source/SDL2-2.0.16/_install/* ./ -rf
$cp /home/pi/source/x264-master/_install/* ./ -rf
$cp /home/pi/source/ffmpeg-4.4/_install/* ./ -rf
