编译安装MPlayer好麻烦.其实centos也可以用yum安装 MPlayer. (rhel也可用)
看一下centos 5的部分:
CentOS 5
首先确定你安装了ProtectBase .
Protectbase
yum-protectbase在CentOS 5包仓库里面有提供:
#yum install yum-protectbase
在CentOS 5里面这个插件默认启动 .
编辑/etc/yum.repos.d/CentOS-Base.repo ,在 [base] 、[update] 、[centosplus] 段末加上一行:
protect=1
让 [centosplus] 段失效如下:
enabled=0
编辑/etc/yum.repos.d/CentOS-Base.repo ，在其它段的最后加上如下一行：
protect=0
rpmforge
下载rpmforge-release包.选择下面两个的其中一个, 依赖于你的机器.如果不能确定用哪一个用以下命令确定 uname -i
(你可以在 http://dag.wieers.com/packages/rpmforge-release/ 找到rpmforge-release包的完全列表，但是推荐使用上面列出两个中的一个).
安装DAG's GPG key
#rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
校验你下载的包
#rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
安全警告: rpmforge-release包把GPG keys注射到你的RPM数据库中. 只要你验证包和相信Dag,它应该是安全的.
安装包
#rpm -ivh rpmforge-release-0.3.6-1.el5.rf.*.rpm
这一步会加入yum仓库配置文件，注射合适的GPG keys.
用以下命令测试:
#yum check-update
应该会有以下两行输出:
Loading "protectbase" plugin
...
76 packages excluded due to repository protections
上面的数字可能不同, 但应该有几种包显示会排除在外.
如果是这样大概它可以运转了，试着你这样安装一些东西 ：
#yum install mplayer
PS: 发现一个MPlayer的另一个前端SMPlayer也可以使用.没有编译好的RPM包.但是这个 SUSE的RPM包可以用.
/etc/yum.repos.d/CentOS-Base.repo内容示范：
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

ps:当然，要想播放rm/rmvb还需要将codecs和wincodecs解压到/usr/lib,就是把codecs解压到/usr/lib/codecd, wincodecd解压到/usr/lib/wincodecs。这点这里有说。
