Centos7 编译安装ffmpeg带libx264 （附带源码包）【显哥出品，必为精品】

一、环境准备

yasm源码包下载： wget  https://download.lixian.fun/Linux_LNMP_packers/yasm-1.3.0.tar.gz
x264源码包下载： wget https://download.lixian.fun/Linux_LNMP_packers/x264.tar.gz
ffmpeg源码包下载： wget https://download.lixian.fun/Linux_LNMP_packers/ffmpeg-snapshot.tar.bz2
nasm源码包下载： wget https://download.lixian.fun/Linux_LNMP_packers/nasm-2.13.03.tar.gz

上面是本博客系统内的安装包，直接在终端 wget 下载即可，如果链接失效

执行官方的地址（下载较慢）

ffmpeg（官方的目前是4.1的压缩包）wget https://ffmpeg.org/releases/ffmpeg-4.1.tar.bz2
x264（官方的）git clone https://git.videolan.org/git/x264.git
nasm（官方的）wget https://www.nasm.us/pub/nasm/releasebuilds/2.14.02/nasm-2.14.02.tar.bz2
yasm（官方的）http://yasm.tortall.net/Download.html

依赖包安装

yum install -y autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel bzip2

二、编译安装yasm

#下载或者上传后解压
[root@ecs-7f06-10 ~]# tar xf yasm-1.3.0.tar.gz
[root@ecs-7f06-10 ~]# cd yasm-1.3.0/

[root@ecs-7f06-10 yasm-1.3.0]# ./configure --prefix=/usr/local/yasm

[root@ecs-7f06-10 yasm-1.3.0]# make && make install

三、编译安装nasm

编译x264库之前必须安装nasm组件，不然编译x264会失败

[root@ecs-7f06-10 ~]# tar xf nasm-2.13.03.tar.gz
[root@ecs-7f06-10 ~]# cd nasm-2.13.03
[root@ecs-7f06-10 ~/nasm-2.13.03]# ./configure
[root@ecs-7f06-10 ~/nasm-2.13.03]# make && make install

四、编译安装x264

[root@ecs-7f06-10 ~]# tar xf x264.tar.gz
[root@ecs-7f06-10 ~]# cd x264/
[root@ecs-7f06-10 x264]# ./configure --prefix=/usr/local/x264 --enable-shared --enable-static --enable-yasm
[root@ecs-7f06-10 x264]# make && make install

五、编译安装ffmpeg

[root@ecs-7f06-10 ~]# tar xf ffmpeg-snapshot.tar.bz2
[root@ecs-7f06-10 ~]# cd ffmpeg
[root@ecs-7f06-10 ~/ffmpeg]# ./configure --prefix=/usr/local/ffmpeg --enable-libx264 --enable-gpl --enable-shared  --extra-cflags=-I/usr/local/x264/include --extra-ldflags=-L/usr/local/x264/lib  --enable-pic
[root@ecs-7f06-10 ~/ffmpeg]# make && make install

六、配置环境变量

[root@ecs-7f06-10 ~]# vim /etc/profile
export PATH=$PATH:/usr/local/ffmpeg/bin:/usr/local/yasm/bin:/usr/local/x264/bin
[root@ecs-7f06-10 ~]# source /etc/profile

配置库路径

#编辑ld.so.conf文件，并且在最下面插入两行路径
[root@ecs-7f06-10 ~]# vim /etc/ld.so.conf
/usr/local/ffmpeg/lib
/usr/local/x264/lib
[root@ecs-7f06-10 ~]# ldconfig

七、运行FFmpeg

[root@ecs-7f06-10 ~]# ffmpeg -encoders | grep libx264
