fedora15硬盘安装请见：http://www.linuxsight.com/blog/1953

安装完fedora15之后，默认的fedora是不能播放mp3，rmvb等视频格式的。因为这些都是闭源或者有版权保护或者授权方式跟GPL有冲突的软件。

我们需要以下步骤来完成fedora15多媒体播放：

1、先安装快速选择源（这一步不是必要的，主要是可以节省时间）

[root@linuxsight linuxsight]# yum install yum-fastestmirror

已加载插件：langpacks, presto, refresh-packagekit

设置安装进程
解决依赖关系
--> 执行事务检查
---> Package yum-plugin-fastestmirror.noarch 0:1.1.30-2.fc15 will be 安装
--> 完成依赖关系计算

2、去 http://rpmfusion.org/Configuration 添加源

安装官方提示，fedora15只需：

[root@linuxsight linuxsight]# yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-rawhide.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-rawhide.noarch.rpm
已加载插件：fastestmirror, langpacks, presto, refresh-packagekit
设置本地安装进程
rpmfusion-free-release-rawhide.noarch.rpm                |  13 kB     00:01
诊断 /var/tmp/yum-root-X52set/rpmfusion-free-release-rawhide.noarch.rpm: rpmfusion-free-release-15-0.1.noarch
/var/tmp/yum-root-X52set/rpmfusion-free-release-rawhide.noarch.rpm 将被安装

确定吗？[y/N]：y

会看到系统会自动把依赖的包全部安装完成，这时候打开MP3，已经可以播放了。此时MPG也可以。

4、播放RMVB，AVI （因为这个时候许多许多包如xvidcore已经安装完毕了，只需要多一个包gstreamer-ffmpeg）

[root@linuxsight linuxsight]# yum install gstreamer-ffmpeg
已加载插件：fastestmirror, langpacks, presto, refresh-packagekit
