centos 在CentOS下编译FFmpeg

所需软件

准备

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

新版还加了下面的
cmake freetype-devel  mercurial 

编译yasm

tar -zxvf yasm-1.2.0.tar.gz 

cd yasm-1.2.0 ./configure --prefix=/usr/local

make && make install

. ~/.bash_profile

编译fdk_aac

tar -zxvf fdk-aac-0.1.1.tar.gz 

cd fdk-aac-0.1.1

autoreconf -fiv ./configure --prefix=/usr/local

make &&  make  install

编译x264

cd x264 //如果之前安装过FFmpeg,会自动链接lavf,如果不想链接lavf,可添加--disable-lavf ./configure --prefix=/usr/local --enable-static  --enable-shared

make  && make install

编译FFmpeg

cd ffmpeg

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig export PKG_CONFIG_PATH 或把上面2行加到vim ~/.bash_profile
source ~/.bash_profile

 echo $PKG_CONFIG_PATH


 ./configure --prefix=/usr/local  --extra-cflags=-I/usr/local/include \   --extra-ldflags=-L/usr/local/lib   --bindir=/usr/local/bin \   --extra-libs="-ldl"  --enable-gpl  --enable-nonfree   --enable-libfdk_aac    --enable-libx264  --enable-shared   make  &&  make install

hash -r . ~/.bash_profile

接着输入ffmpeg检查是否安装成功，

如果出现如下错误：

error while loading shared libraries: libavdevice.so.54

解决方法：

vim  /etc/ld.so.conf 添加 /usr/local/lib /usr/local/lib64 后 # ldconfig
