Ubuntu Multimedia HOWTO


Introduction
------------
"Will Warty Warthog / Ubuntu include complete multimedia support?"


Ubuntu Linux [1] is a Debian-based, desktop Linux distribution whose name
means "humanity to others." The philosophy behind this GNU/Linux
distribution and the great selection of packages make you feel good that
you're using it. The lack of multimedia support, however, leaves your
digital media desires unsated.

"We're still working out some of the difficult legal / policy issues
involved with multimedia support. Warty Warthog will include some
multimedia support, we just need to find out what we can safely and freely
do."

This HOWTO details the installation and configuration of applications
essential to your media enjoyment on Ubuntu.


Update It
---------
If you've installed Ubuntu, and you should have a fresh install for this
HOWTO, then you're already familiar with its default use of sudo. You'll
be using sudo a lot.

The first step towards an Ubuntu multimedia powerhouse is to make sure your
box is up-to-date [2].

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade


MPlayer
-------
It's time to grab all of the packages needed to install MPlayer. MPlayer
is the most versatile media player available for GNU/Linux - video, audio,
X, no X - it very well may be the only player you'll need. Let's start with
gcc/g++ and other dependencies, and then grab the MPlayer source.

$ sudo apt-get install manpages-dev
$ sudo apt-get install autoconf
$ sudo apt-get install automake
$ sudo apt-get install libtool
$ sudo apt-get install flex
$ sudo apt-get install bison
$ sudo apt-get install gcc-doc
$ sudo apt-get install g++
$ sudo apt-get install x-window-system-dev
$ sudo apt-get install libgtk1.2-dev
$ sudo apt-get install libpng-dev

Have your Warty Warthog CD handy and accept any extra packages, e.g. the
libtool install will also install gcc. We'll use a US mirror for the
MPlayer packages and assume you're working in your home directory. Download
MPlayer, codecs, English fonts and the default blue skin.
Internationalization and slick graphics are up to you.

$ wget http://ftp3.mplayerhq.hu/MPlayer/rel....0pre5.tar.bz2
$ wget http://ftp3.mplayerhq.hu/MPlayer/rel...040922.tar.bz2
$ wget http://ftp3.mplayerhq.hu/MPlayer/rel...8859-1.tar.bz2
$ wget http://ftp3.mplayerhq.hu/MPlayer/Skin/Blue-1.4.tar.bz2

Using the README from mplayerhq.hu [3] as a baseline, install the codecs
with the following commands.

$ tar -xjf essential-20040922.tar.bz2
$ sudo mkdir -p /usr/local/lib/codecs
$ sudo cp essential-20040922/* /usr/local/lib/codecs/

Time to compile MPlayer. Issue these commands.

$ tar -xjf MPlayer-1.0pre5.tar.bz2
$ cd MPlayer-1.0pre5
$ ./configure --enable-gui
$ make
$ sudo make install

Now install the fonts and skin.

$ cd
$ tar -xjf font-arial-iso-8859-1.tar.bz2
$ sudo cp font-arial-iso-8859-1/font-arial-14-iso-8859-1/* /usr/local/share/mplayer/font/
$ tar -xjf Blue-1.4.tar.bz2
$ sudo mkdir -p /usr/local/share/mplayer/Skin/default
$ sudo cp -r Blue/* /usr/local/share/mplayer/Skin/default/

Finally, copy over the included conf files.

$ sudo cp MPlayer-1.0pre5/etc/* /usr/local/etc/mplayer/

Test your install by launching the graphical version of MPlayer.

$ gmplayer

QuickTime, WindowsMedia, MPEG, avi - you should be able to play just about
anything. Give yourself quick access to MPlayer by adding a launcher to
the top GNOME panel. Right click on the panel and click Add to Panel...
Select Custom Application Launcher and click Add. Use the following
information and click OK.

Name: MPlayer
Command: /usr/local/bin/gmplayer
Icon: /usr/local/share/mplayer/Skin/default/icons/32x32.png


Playing DVDs
------------
The Ubuntu Wiki discusses restricted formats [4], which includes CSS and
DVD playback. To add DVD playback capability to Ubuntu, use the Synaptics
Howto [5] to add ftp://ftp.nerim.net/debian-marillat to your sources list
(unstable, main). Then sync your package index.

$ sudo apt-get update

Grab the infamous DeCSS.

$ sudo apt-get install libdvdcss2

Add a dvd link and enjoy DVDs with MPlayer and Ubuntu.

$ sudo ln -s /media/cdrom0 /dev/dvd


XMMS
----
With your video needs taken care of, we can move on the audio portion of
our show by installing XMMS.

$ sudo apt-get install libmikmod2
$ sudo apt-get install xmms

Logging out and logging back in will find XMMS already in the Applications/
Multimedia menu. And there it is - instant Ogg/mp3/jukebox/streaming audio

goodness.


A Little Perl
-------------
For streaming internet radio, you can of course use XMMS. Set your
preference in Firefox and you're good to go. I listen to a few stations
regularly, and I always have a gnome-term open. With those things in mind,
I've found it much more convenient to write a Perl script that uses MPlayer
to stream my favorite music.

#!/usr/bin/perl -w

# mplay.pl -
# command line streaming of your fav stations
# usage: mplay <channel>

use strict;

help() unless defined(my $chan = shift);

if ($chan =~ /bass/) {
system("mplayer http://us-dc1.streams.bassdrive.com:8012");
}
elsif ($chan =~ /cryo/) {
system("mplayer http://207.200.96.225:8022");
}
elsif ($chan =~ /di/) {
system("mplayer http://205.188.234.68:8006");
}
elsif ($chan =~ /ind/) {
system("mplayer http://130.240.207.88:9090");
}
elsif ($chan =~ /talk/) {
system("mplayer http://broadcast.rantradio.com:9010");
}
else { help(); }

sub help {

print <<EOF;

Usage: mplay <channel>

Channels:
bass - BassDrive
cryo - Cryosleep
di - Digitally Imported
ind - RantRadio Industrial
talk - RantRadio Talk

EOF

exit;
}

"mplay rant" plays RantRadio's 128-bit industrial stream quickly and
without a browser. If you need your terminal, "q" stops the stream, do
your deed, and up arrow gets the stream right back (or of course Ctrl+
Shift+T for a new tab in gnome-terminal).


Conclusion
----------
Ubuntu Linux is an impressive distribution. Even more impressive is the
conviction of the developers. "The most important thing about Ubuntu is
not that it is available free of charge, but that it confers rights of
software freedom on the people who install and use it." They put their
money where their apt is. So as a GNU/Linux user, the tasks detailed
above are trivial compared to the decisions made not to include such
support.

Please support free software developers. Continue to use Ubuntu.
Contribute to the Ubuntu Linux community. And watch Batman: Dead End
while you're doing it [6].

remove rhythmbox.

I tried the above instructions, but when it comes to installation of the libpng, I get this error:

Package libpng-dev is a virtual package provided by:
libpng12-dev 1.2.5.0-7ubuntu1
You should explicitly select one to install.
E: Package libpng-dev has no installation candidate


So I can't install this empty package, and everything fails. Is there a place to download a non-virtual package? Set apt sources differently? I googled and found absolutely nothing useful.
Thanks!

kkubasik

keep in mind, questions are better placed in the quesiton section, its forum policy, but they probably added another libpng to the mirrors, use the complete name of the package, not jist libpng and see if that helps.
