Chapter 9: A Distributed Grid Application

Installing mplayer and mencoder

As user root you can install mplayer using yum. Begin by making sure the prerequisite libraries are installed:

You will need the lame package referenced on this page:
http://rpm.greysector.net/mplayer/requirements.html

You can retrieve and install this library for Fedora Core 4 with the following commands executed as user root:

wget http://rpm.livna.org/fedora/4/i386/lame-3.96.1-0.lvn.4.4.i386.rpm

rpm -Uvh lame-3.96.1-0.lvn.4.4.i386.rpm

Next configure your yum so that it knows to look in the mplayer repository (known as 'greysector'):

[root@nodeA ~]# cd /etc/yum.repos.d/
[root@nodeA yum.repos.d]# wget http://rpm.greysector.net/yum/greysector.repo
--11:29:18-- http://rpm.greysector.net/yum/greysector.repo
=> `greysector.repo'

[root@nodeA yum.repos.d]# cat greysector.repo
[greysector]

Next download and import the key for the repository so that PRM does not complain:

[root@nodeA ~]# wget http://rpm.greysector.net/greysector-pubkey.txt
--11:31:12-- http://rpm.greysector.net/greysector-pubkey.txt

[root@nodeA ~]# rpm --import greysector-pubkey.txt

With the repository configured you can now easily install mplayer and mencoder. Simply answer 'y' when prompted:

[root@nodeA ~]# yum install mplayer
[root@nodeA ~]# yum install mencoder

You can verify that both mplayer and mencoder are installed (our application will only use mencoder but the mplayer libraries are necessary):

[root@nodeA ~]# which mplayer
/usr/bin/mplayer
[root@nodeA ~]# which mencoder
/usr/bin/mencoder
