Media Systems: Incorporating the TV and the HiFi - Smart Home Automation with Linux and Raspberry Pi - page 88

On Debian, for example, an extra repository is added by placing a single line in the /etc/apt/sources.list file:
deb http://www.debian-multimedia.org lenny main
This is followed by the following traditional process:
apt-get update
apt-get install libdvdcss2
Sometimes you have to download and install the package manually. That command line invocation would be
as follows:
dpkg -i libdvdcss2_1.2.10-1_i386.deb
Alternatively, the source installation would be as per the INSTALL file, probably something like the trinity of this:
./configure
make
make install # as root
Once you can use VLC to play DVDs, you know the library is successfully installed and is consequently available
to all the main media player applications, such as mplayer , totem , xine , and so on.
When ripping DVDs, you have to consider the amount of hard disk space that you want to devote to your
collection, whether you want (or need) the DVD menus, and on what devices they are being played. Ultimately,
there are two choices.
Rip As ISO
Rip As ISO makes a raw copy of the entire disc and stores it as a file. This is the easiest process to initiate, because you
simply invoke the following:
dd if=/dev/dvd of=TheOffice-series1.iso bs=1024
This will generally require between 4GB and 8GB of space and includes all of the DVD menus, titles, chapters,
and subtitles. Movie players such as VLC will be able to handle interactive components such as menus, but others
won't. This is especially true of units that don't support the DVD logo because they won't have the CSS code as well as
of smaller low-power devices such as MediaMVP. In the case of the latter, you can partially solve the problem by using
VLC to remotely transcode the movies, but it still won't be able to handle the processing of the DVD menus.
As with all disk images, Linux is able to mount them to a directory so that they can be read and so that their files
can be queried normally. This can be done automatically through the desktop or with the following:
mount -t udf -o loop TheOffice-series1.iso dvdimage
Note that you cannot mount the image to your usual DVD location (such as /dev/dvd ) because that is a block
device, and you can only mount images to a directory.
