h3. Hardware

In this release, two reference configurations are proposed. One uses an USB web camera the other uses a video capture card, such as the Hauppauge PVR350. In both cases, using a VGA capture card model VGA2USB or superior is recommended.

h3. Software Installation

Galicaster is based on Open Source technologies.

The recommended OS for this release is Ubuntu 10.10
The installation process consists of five steps: installing dependencies, checking configuration, downloading software, configuring and running.

h6. 1.\- Install dependences.

Galicaster requires the following software to be installed:

* Gstreamer
* python-setuptools and pip
* iCalendar
* pyCurl
* 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 \
gstreamer0.10-plugins-base gstreamer0.10-plugins-base-apps gstreamer0.10-plugins-good \
gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse
$ sudo apt-get install python-pip python-setuptools
$ sudo pip install icalendar
$ sudo apt-get install python-pycurl
$ sudo apt-get install v4l-conf ivtv-utils guvcview
{code}

In ubuntu 11.04 and above is recommended installing v4l-utils instead of ivtv-utils.

h6. 2.\- Check configuration.

Launch the following commands from a shell to verify that all dependencies are installed:

{code:none}
$ python --version
Python 2.6.6

$ 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
$ gst-launch-0.10 videotestsrc num-buffers=25 ! video/x-raw-yuv,width=800,height=600,framerate=24/1 ! ffmpegcolorspace ! x264enc pass=5 quantizer=22 speed-preset=4 profile=1 ! queue ! avimux ! filesink location=out.avi
$ file out.avi
out.avi: RIFF (little-endian) data, AVI, 800 x 600, ~24 fps, video: H.264 X.264 or H.264
$ rm out.avi
{code}

h6. 3.\- Download software

Download the software from [this site|http://webfiler.teltek.es/webfiler/galicaster/galicaster-1.0.0-rc.tgz].

Uncompress it using tar:

{code}
$ tar xzf galicaster-1.0.0-rc.tgz
$ cd galicaster-1.0.0-rc
{code}


h6. 4.\- Configure Galicaster

Galicaster configuration is in the file {{conf.ini}}.

The simplest way to get started with Galicaster is dowloading any of the pre-existing conf.ini files for any of the reference configurations proposed:
* [Video Capture Card configuration|http://webfiler.teltek.es/webfiler/galicaster/configs/hau/conf.ini]
* [WebCam USB configuraion|http://webfiler.teltek.es/webfiler/galicaster/configs/webcam/conf.ini]





The values are in the file {{conf.ini}}:


Sections:

* {{basic}}
** {{repository}}: path to the working folder.
** {{admin}}: enables admin mode (True\|False)
** Example:
{code:none}
[basic]
repository = /mnt/videos/Repository
admin = True
{code}

* {{screen}}
** {{right}}: Name of the video device in the track list to be shown in the right screen (None to deactivate).
** {{left}}: Name of the video device in the track list to be shown in the left screen (None to deactivate).
** {{cursor}}: Shows or hides the cursor. (True\|False)
** Example:
{code:none}
[screen]
right = Epiphan
left = Hauppagge
cursor = True
{code}

* {{ingest}}
** The data to connect Galicaster to an Opencast-Matterhorn server.
** Example:
{code:none}
[ingest]
default = True
username = matterhorn_system_account
host = http://admin.matterhorn.es:8080
password = CHANGE_ME
workflow = full
{code}

* {{trackN}}
** Values common to all devices:
*** {{name}}: Name assigned to the device.
*** {{device}}: Device type. (v4l2\|vga2usb\|webcam\|hauppage\|pulse)
*** {{flavor}}: Matterhorn "flavor" associated to the track. (presenter\|presentation\|other)
*** {{location}}: Device's mount point in the system (e.g. /dev/video0).
**** For PulseAudio devices run:
{code:none}
$ pactl list | grep "Source" -A 5
{code}
and use "Name:" as the {{location}} field.
*** {{file}}: The file name where the track will be recorded.
*** {{active}}: Whether the device will be played and recorded. (True\|False)
** Values in audio (pulse) devices:
*** {{playing}}: Indicates if the audio, apart from being recorded, is played. (True\|False)
*** {{vumeter}}: Activates data sending to the program's vumeter. (True\|False) Only one device should be activated.
*** {{amplification}}: Gstreamer amplification value: < 1 decreases and > 1 increases volume. Values between 1 and 2 are commonly used.
** Example:
{code:none}
[track1]
name = Hauppagge
loc2 = /dev/hauprevideo
loc3 = /dev/haupreaudio
location = /dev/haucamera
file = CAMERA.mpg
device = hauppage
flavor = presenter
active = False

[track2]
name = Epiphan
active = False
location = /dev/screen
file = SCREEN.avi
device = vga2usb
