ffmpeg+libmp3lame库源码安装教程(CentOS)

lame--libmp3lame的安装包,支持MP3编码;yasm--NASM的重写,用于编译ffmpeg。

 

1.下载

ffmpeg下载链接:http://ffmpeg.org/download.html

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

lame下载接:https://sourceforge.net/projects/lame/files/lame/

 

2.编译安装

2.1安装lame

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

2.2安装yasm

tar -zxf yasm-1.3.0.tar.gz
cd yasm-1.3.0
sed -i 's#) ytasm.*#)#' Makefile.in
./configure
make
make install

2.3安装ffmpeg

tar -jxf ffmpeg-3.4.tar.bz2
cd ffmpeg-3.4
./configure --enable-shared --enable-libmp3lame
make
make install

 

3.配置调整

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
