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://www.pawprint.net/news/article/105/Compiling-FFMpeg-on-Centos-5/
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.
