The Pi as a Home Theatre PC - Raspberry Pi User Guide - page 116

ONE OF THE most popular tasks for a Pi to carry out is that of a home theatre PC, or HTPC.
The Broadcom BCM2835 at the Pi's heart is specifically designed as a multimedia power-
house, originally developed for use in HTPCs.

The graphics portion of the BCM2835 system-on-chip (SoC) design, a Broadcom VideoCore
IV module, is capable of full-speed high-definition video playback using the popular H.264
format. The chip is also able to play back audio files in a variety of formats, both through the
analogue 3.5 mm audio output and digitally via the HDMI port.

The small size, low power draw and silent operation combine to make the Pi a tempting
device for home theatre enthusiasts. A variety of distributions and software packages
designed to turn the Pi into a user-friendly home theatre PC have appeared since its launch,
but you don't necessarily need to give up your existing operating system to get started.

Playing Music at the Console
If you're a developer, you will likely spend most of your time at the Pi's console. With the major-
ity of music playback software being aimed at desktop use, it can be a quiet experience—but it
doesn't have to be.

The Pi supports a powerful text-based music playback package called moc (which stands for
music on console ). Unlike other tools (such as LXMusic ), moc can be installed and used even
when there is no graphical user interface (GUI) installed on the Pi.

To get started, install the moc package from your distribution's repositories. For the Raspbian
distribution, this is as simple as typing the following command at the console or in a terminal
window:

sudo apt-get install moc

Some distributions already have another tool called moc , which has nothing to do with audio
playback. If you find that installing moc doesn't give you the result you're expecting, try
substituting mocp as the package name.

TIP

If you spend a lot of time outside of the graphical user interface and working at the console,
moc is a great choice for music playback. Unlike other tools, it runs in the background, mean-
ing there's no interruption to your music if you start doing something else.

To load moc , the command is mocp rather than moc . The reason for this is that there's
another tool which uses the command moc , so a different name was chosen to prevent the
operating system from getting confused between the two packages.
