h6. 3.\- Download software
Download the software from [this site|http://webfiler.teltek.es/webfiler/galicaster/galicaster-1.0.0-rc1.tgz].
Uncompress it using tar:
{code}
$ tar xzf galicaster-1.0.0-rc1.tgz
$ cd galicaster-1.0.0-rc1
{code}
{anchor:config}
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|Hardware recommendations#videocapturecard] \- [conf.ini|http://webfiler.teltek.es/webfiler/galicaster/configs/hau/conf.ini]
* [WebCam USB configuraion|Hardware recommendations#webcamusb] \- [conf.ini|http://webfiler.teltek.es/webfiler/galicaster/configs/webcam/conf.ini]
This is the structure of the {{conf.ini}} file:
{anchor:config_basic}
* Section {{basic}}
** {{repository}}: absolute path to the working folder. If not specified, a {{Repository}} directory in the user's home will be used.
** {{admin}}: enables admin mode (True\|False)
*** *False*: By default, the user will only be allowed to make recordings. Galicaster will operate as a [GClass|Galicaster:Galicaster Class]
*** *True*: Apart from recording, the user can edit metadata, play and manage the recordings. Galicaster will behave as a [GMobile|Galicaster:Galicaster Mobile]
** Example:
{code:none}
[basic]
repository = /mnt/videos/Repository
admin = True
{code}
{anchor:config_screen}
* Section {{screen}}
** {{right}}: Name of the video device in the [track list|#config_track] to be shown in the right screen (None to deactivate).
** {{left}}: Name of the video device in the [track list|#config_track] to be shown in the left screen (None to deactivate).
** {{cursor}}: Shows or hides the pointe. Useful if using a tactile screen (True\|False)
** Example:
{code:none}
[screen]
right = Epiphan
left = Hauppagge
cursor = True
{code}
{anchor:config_ingest}
* Section {{ingest}}
** The data to connect Galicaster to an Opencast-Matterhorn server.
** Example:
{code:none}
[ingest]
active = True
default = True
username = matterhorn_system_account
host = http://admin.matterhorn.es:8080
password = CHANGE_ME
workflow = full
{code}
{anchor:config_allows}
* Section {{allows}}
** {{manual}}: Allows full manual control of a recording. (True\|False)
** {{start}}: if {{manual}} it's false, allows manual start of a recording. (True\|False)
** {{stop}}: if {{manual}} it's false, allows manual stop of a recording - also scheduled ones. (True\|False)
** {{pause}}: allows pausing a recording - independent from manual. (True\|False)
** {{overlap}}: if activated, a manual recording takes priority over a scheduled one, meaning it won't stop when the scheduled should start. Otherwise, the manual will be stopped and the scheduled one started.(True\|False)
** Example:
{code:none}
[allows]
manual = True
start = False
stop = False
pause = True
overlap = False
{code}
{anchor:config_track}
* Section {{trackN}}
** A section for each device used in the capturer. Each section is set according to the device type: {{hauppauge}}, {{pulse}}, {{v4l2}} or {{vga2usb}}:
*** *hauppauge*: Audio and Video device.
**** Admitted values:
***** {{name}}: Name assigned to the device.
***** {{device}}: Device type: hauppage
***** {{flavor}}: Matterhorn "flavor" associated to the track. (presenter\|presentation\|other)
***** {{location}}: Device's mount point of the MPEG output
***** {{locprevideo}}: Device's mount point of the RAW output
***** {{locpreaudio}}: Device's mount point of the PCM output
***** {{file}}: The file name where the track will be recorded.
***** {{active}}: Whether the device will be played and recorded. (True\|False)
**** Example:
{code:none}
[track1]
name = Hauppagge
location = /dev/haucamera
locpreavideo = /dev/hauprevideo
locpreaudio = /dev/haupreaudio
file = CAMERA.mpg
device = hauppage
flavor = presenter
active = False
{code}
*** *pulse*: Audio device.
**** Admitted values:
***** {{name}}: Name assigned to the device.
***** {{device}}: Device type: pulse
***** {{flavor}}: Matterhorn "flavor" associated to the track. (presenter\|presentation\|other)
***** {{location}}: PulseAudio source name. Use _default_ to select the same Input as the Sound Control
****** to list 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)
***** {{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}
[track3]
name = AudioSource
vumeter = Active
location = default
file = sound.mp3
device = pulse
flavor = presenter
active = False
amplification = 2.0
{code}
*** *v4l2*: Video device
**** Admitted values:
***** {{name}}: Name assigned to the device.
***** {{device}}: Device type: v4l2
***** {{flavor}}: Matterhorn "flavor" associated to the track. (presenter\|presentation\|other)
***** {{location}}: Device's mount point in the system (e.g. /dev/video0).
***** {{file}}: The file name where the track will be recorded.
***** {{active}}: Whether the device will be played and recorded. (True\|False)
***** {{caps: }} GStreamer cappabilities of the device (mimetype=video/TYPE, framerate=X/Y,width=A,height=B)
TYPE: (jpeg\|x-raw-int)
Use GVUCView tool to know wich capabilities are compatible with your device

***** Videocrop: Margin in pixels to be cutted. Useful to set a 4:3 proportion on a HD webcam.{{videocrop-top}}, {{videocrop-bottom,}} {{videocrop-left, videocrop-right}} (optional).
**** Example:
{code:none}
[track4]
name = Webcam
