VLC media player (commonly known as VLC) is a portable, free and open-source, cross-platform media player and streaming media server written by the VideoLAN project. VLC media player supports many audio and video compression methods and file formats, including DVD-Video, video CD and streaming protocols. It is able to stream media over computer networks and to transcode multimedia files.[8]
The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. Many of VLC’s codecs are provided by the libavcodec library from the FFmpeg project, but it uses mainly its own muxer and demuxers and its own protocols implementations. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and OS X by using the libdvdcss DVD decryption library.
For EL7:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-1.noarch.rpm rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
For EL6:
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm
Now:
yum update yum install vlc
以为这样就可以了，谁知报错，一堆的解码器需要依赖关系

先到/etc/yum.repos.d/目录下ls一下，看看它们长得是啥样子。
1、安装epel和remi的repository：
[root@localhost ~]#yum localinstall --nogpgcheck http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
老 外写那篇文章时epel-release的版本是6.7，他当时给的下载链接是“http://download.fedoraproject.org /pub/epel/6/i386/epel-release-6-7.noarch.rpm”，可这个链接目前已经无效了，到 fedoraproject找到了epel新的6.8的版本。
[root@localhost ~]#yum localinstall --nogpgcheck http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
2、安装rpmfusion的repository：
下面两个rpm包都要安装
[root@localhost ~]#yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm
[root@localhost ~]#yum localinstall --nogpgcheck http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm
上述两个步骤完成后再到/etc/yum.repo.d/目录下执行一下ls看看又有啥变化。
================================
然后再执行 yum install vlc就可以了
PS：具体原因没搞明白，因为要用vlc，暂时先用着吧
后面发现个超简单的 http://www.cnblogs.com/bushe/p/4027882.html
root下：# cd /etc/yum.repos.d/# wget http://pkgrepo.linuxtech.net/el6/release/linuxtech.repo //若不成功多试几次# yum list *vlc*# yum -y install vlc# exit
$ vlc//成功
