Galicaster is based on Open Source technologies.

Before starting the installation process, please make sure that:
* If you already have a Galicaster running, please check the [upgrading|Galicaster:Upgrading from older versions] documentation.
* Your equipment meets Galicaster's [Hardware Recommendations|Galicaster:Hardware recommendations].
* You are running a Linux-based OS. The recommended distribution is [Ubuntu 12.04|http://releases.ubuntu.com/12.04/]. Be careful selecting 32 or 64 bit on the Desktop release.
* Your capture devices are configured as indicated in the [Cookbook|Cookbook].

The installation process consists of six steps: [installing dependencies|#dependences], [checking the configuration|#check], [downloading software|#download], [configuring Galicaster|#config], [checking the connection to a Matterhorn core|#matterhorn] and [testing it|#running].

As a faster alternative, Galicaster can be installed using a [debian package format|#debpkg].

* Capture card configuration tools



{code:none}
$ sudo apt-get install \
gstreamer0.10-ffmpeg gstreamer0.10-alsa gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse \

h6. 2.\- Check configuration.

Run the following commands in a shell in order to verify that all dependencies are installed:

{code:none}
$ python --version
Python 2.7.3

$ python -c "import pygtk; pygtk.require('2.0')"
$ python -c "import pygst; pygst.require('0.10')"
$ python -c "import pycurl"
$ python -c "import icalendar"

$ gst-launch-0.10 videotestsrc num-buffers=25 ! video/x-raw-yuv,width=800,height=600,framerate=24/1 ! ffmpegcolorspace ! xvimagesink

$ tar xzf galicaster-1.2.0.tgz
$ cd galicaster-1.2.0
{code}

_Recommendation: Move galicaster-1.2.0 folder to a familiar location_


{anchor:config}

h6. 4.\- Configure Galicaster

Galicaster configuration is in the files {{conf-dist.ini}} and {{conf.ini}}. \*Any duplicated value on {{conf.ini}} will prevail over the same ones on {{conf-dist.ini}}.

All the application parameters can be set up in these files, such as:

* Operation mode of the application: I.e. whether Galicaster will work as [Galicaster Class|Galicaster:Galicaster Class], designed to be used in a classroom environment, or as [Galicaster Mobile|Galicaster Mobile], a portable recording station.
* Devices used in the capturer, and their configuration.
* Server information to ingest.
* User privileges to control the recorder.

{anchor:matterhorn}

h6. 5.\- Opencast Matterhorn Connection

One of the key features of Galicaster is the connection to the publishing platform. If you are using Matterhorn as your media publishing and distribution system, you need to configure Galicaster to work as a Capture Agent and connect it to your core machine. Here are some tips to do so:

* Your Galicaster unit needs access to your Matterhorn Core network.
* Use a valid *host* URL. It may be a fully-qualified name or simply an IP address.
* If your Matterhorn Core is not running in the default port (80), then you need to explicitly include it in the URL (i.e. {{http://<host_name_or_ip>:8080}}).
* The use of the {{http://}} prefix is mandatory.
* You need to use a Matterhorn account which authenticates via Digest (usually, this account is set up in the {{config.properties}} file in your Matterhorn server). A regular account will not work.
* Remember to activate the connection in Galicaster (in the configuration file, section {{ingest}}, value {{active}}).
* A wrong workflow will raise an error in Matterhorn. Please make sure you use a workflow name that exists in the machine you connect Galicaster to.
* *Workflow parameters are available but optional. A unexisting or wrong parameter won't affect the process, a mistaken value will be considered as "False".*
* Check your Galicaster unit is registered as a Capture Agent in the Admin Tools section of your Matterhorn installation.
** The log (in {{/tmp/galicaster.log}}) will record any problem occurring on the connection to the Matterhorn server.

If your Galicaster is registered as a Capture Agent you should be able to receive the recording schedule, if any, and ingest any recordings in Galicaster to the Matterhorn Core. If this is not so, please review all the steps above and try again. The logs in Matterhorn and Galicaster will give you the hints to know what is failing.


{anchor:running}

h6. 6.\- Run Galicaster

Galicaster Class is launched with the command:

{code:none}
$ ./run_galicaster.py
{code}

The [User Guide] section contains Galicaster's user manual. Should you have any questions, please visit the [F.A.Q.|FAQ] section where some common questions are already answered.

h4. Galicaster Debian Package \[Experimental\]

To install Galicaster using the debian package, [download it|http://webfiler.teltek.es/webfiler/galicaster/galicaster_1.2.0_all.deb] and run in a shell:

{code:none}
sudo dpkg -i galicaster_1.2.0_all.deb
{code}

or double-click over on the file browser, running it with the Ubuntu Software Center.

If the Ubuntu Software Center installation is selected, a warning appear since Galicaster is not packaged following the standards strictly, ignore it and continue the installation

Using this method, Galicaster will be installed on /usr/share/galicaster, and the configuration files should placed on _/etc/galicaster/conf.ini_ and _/etc/galicaster/profiles_.

To remove it, run on a shell as root:
{code:none}
dpkg -r galicaster
{code}

The files on _/etc/galicaster_ won't be removed, preserving your configuration files. If you want to delete them also, run as root:
{code:none}
rm /etc/galicaster/profiles/*.*
dpkg --purge galicaster
{code}
