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
