反正安装这个下来，特别容易就装上了。 测试没有问题
但编辑文本的话，我还是用vi来的方便。

Let's add the repository by adding an entry into YUM, the default package manager for CentOS.
# sudo nano -w /etc/yum.repos.d/dag.repo
You will need to add the following lines into this file.
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1
Once you have pasted the lines press CTRL-X on your keyboard to exit the
application. You will be asked if you would like to save the file,
simply press Y and then press Enter to accept the default file name. The
program will now exit.
Next we need to add the GPG key that signs each of the packages in the DAG repository but first we need to download it.
# wget http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt
In this file there are a few lines that need to be removed before we can
import it otherwise an error will result. Type the following line to
open the editor.
# nano RPM-GPG-KEY.dag.txt
In this screen you will see several lines and a bunch of random letters and numbers. Delete the following lines:
The following public key can be used to verify RPM packages
downloaded from http://dag.wieers.com/apt/ using 'rpm -K'
if you have the GNU GPG package.
Questions about this key should be sent to:
Dag Wieers <dag@wieers.com>
# sudo rpm --import RPM-GPG-KEY.dag.txt
Installing ffmpeg
Now that we have the key installed for the DAG repository we are ready
to install ffmpeg. To install type the following command:
# sudo yum install ffmpeg
You will be prompted with a list of items that need installed. This
should be approximately 12MB of packages on a fresh CentOS 5.2
installation. Press Y followed by Enter to continue.
