Install mplayer on debian

[Lian Liming <lianliming@realss.com>]

Hi all,
I am using debian/unstable and find i can't find "mplayer" in the
package list. After using "apt-cache search mplayer", i get the
following result:
-----------------------------------------------------------------------------------------------------------------
mga-vid-source - Kernel driver for the back-end scaler on Matrox cards
(source)
mozilla-mplayer - MPlayer-Plugin for Mozilla, Konqueror and OpenOffice.org
xmms-xmmplayer - XMMS plugin that uses MPlayer to play video files
------------------------------------------------------------------------------------------------------------------

That means i can't use "apt-get" to install mplayer. As everyone know,
to install mplayer from the source is a different thing. It has a great
deal of packages and plug-ins.
I just wonder why mplayer is not on the debian apt package list? and how
can i find a easy way to install myplayer on deiban? :)

Thank you for suggestions!
