FFmpeg安装，AAC编码器安装

Intro

This guide is meant to walk system administrators through the process of setting up ffmpeg, x264, and the codecs & libraries required to run the CumulusClips on CentOS 5.5 (or higher) and Red Hat (RHEL) Linux. This is helpful if you purchased a VPS or dedicated server to run CumulusClips, or if you’re a hosting company setting up your infrastructure to support CumulusClips. This guide was adapted from the following two guides:

http://ubuntuforums.org/showthread.php?t=786095

The version numbers of the various downloads were the latest at the time of this writing (9/17/2011). Please check the respective vendors’ sites to ensure you obtain the latest stable version of each library

Prepare Your System

Add EPEL Repository to CentOS / RHEL. Only the core and EPEL repositories are required for this guide. This is to obtains the necessary tools for the install process, not the actual codecs & libraries themselves. Those will be compiled from source.

1 2	wget http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm rpm -Uvh epel-release-5-4.noarch.rpm

Remove any of the codecs that were pre-installed.

1	yum remove libvpx libogg libvorbis libtheora libx264 x264 ffmpeg

Update your system and install the tools required for compiling and installing all the codecs.

1 2	yum update yum install gcc gcc-c++ automake autoconf libtool yasm nasm git subversion

Temporarily disable your firewalls and SELinux

iptables -F service iptables save vi /etc/selinux/config

Set the SELinux value to disabled. Make sure your shared library paths are in order
