一、安装mp3插件和mp4插件，无优先顺序。lame--libmp3lame的安装包，支持MP3编码；yasm--NASM的重写，用于编译ffmpeg

1、安装mp3插件

lame：LAME (Lame Aint an MP3 Encoder) - Browse /lame at SourceForge.net

tar -zxf lame-3.100.tar.gz
cd lame-3.100
./configure
make
make install

yasm：http://www.linuxfromscratch.org/blfs/view/svn/general/yasm.html

tar -zxf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure
make
make install

二、安装mp4插件

nasm：nasm-2.13.03.tar.gz

cd nasm-2.13.03
./configure
make
make install

x264：VideoLAN / x264 · GitLab

cd x264-master
./configure
make
make install

三、安装FFMPEG：Download FFmpeg

cd ffmpeg
./configure --enable-gpl --enable-nonfree --enable-pthreads --enable-libx264 --enable-libmp3lame --disable-x86asm
make
make install

配置：

执行：ffmpeg --version

报错：ffmpeg: error while loading shared libraries: libavdevice.so.57: cannot open shared object file: No such file or directory

解决：编缉/etc/ld.so.conf，新建一行追加：/usr/local/lib；保存后执行命令重加载配置文件：ldconfig

include ld.so.conf.d/*.conf
/usr/local/lib

ldconfig
