Galicaster Configuration

{pop-away:metadata | comments | children | labels}

{section}
{column:width=69%}
There are two types of configuration files: general configuration files and input configuration files:

There are two *general configuration* files: *conf-dist.ini* and *conf.ini*. The idea is to set default values on the first one and use the second to set the current configuration. _If any duplicated value between the two files, conf.ini values will prevail._ Each general configuration file is divided in sections, each one explained below, on this very same page.

In addition Galicaster 1.2 supports a *input profile* logic. Profiles are sets of configuration for devices - tracks - that can be loaded to run together. Profiles are listed on a menu on the welcome page, thus being available only for admin users. To know more about input profile please visit [this page|Galicaster:Input Profiles].

h5. Sections
The files are divided in sections. The beginning of a section is marked by a keyword indicating its title, surrounded by square brackets. Below is a detailed description of the different sections and their contents:

{anchor:config_basic}
h6. Section {{basic}}

* {{admin}}: enables admin mode ({{True\|False}})
** *False*: By default, the user will only be allowed to make recordings. Galicaster will operate as a [Galicaster Class|Galicaster:Galicaster Class]
*** In this mode, tracks are selectable, so only the selected ones will be send back to the server.
** *True*: Apart from recording, the user can edit metadata, play and manage the recordings. Galicaster will behave as a [Galicaster Mobile|Galicaster Mobile]
*** In this mode Matterhorn server won't receive a list of tracks, so all tracks specified will be recorded, packaged and send back to the server.
** Depending on the mode, the capture unit will assume a different capture agent name. A computer named Example will gcExample on Class mode and gcMobileEXample on Mobile mode. The agent name can be set manually on ingest>hostname.
* {{repository}}: absolute path to the working folder. If not specified, a {{Repository}} directory in the user's home will be used.
* {{export}}: absolute path to the export folder for operations. If not specified, exported files will be placed at the user's home folder.
* {{stopdialog}}: Enable/Disable a dialog requesting confirmation to stop the recording. Defaults to True. *(True|False)*
* {{quit}}: Shows or hides the quit button. *(True|False)*

Example:
{code:none}
[basic]
admin = True
repository = /mnt/videos/Repository
export = /home/user/Videos
stopdialog = True
quit = True

{code}

{anchor:config_screen}
h6. 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).

Note that if a profile different from default is selected, they will be ordered automatically via track position

* Example:
{code:none}
[screen]
right = Epiphan
left = Hauppauge
{code}

{anchor:config_ingest}
h6. Section {{ingest}}

* {{active}}: Enables the connection to a Opencast-Matterhorn server *(True|False)*.
* {{manua}}l: Configure the method to automatically ingest the manual recordings. The possible options are: disable the automatic ingestion (none), ingest immediately after the recording (immediately) or ingest nightly all the recordings of the previous day (nightly). Defaults to 'none'. *(none|immediately|nightly)*
* {{scheduled}}: Configure the method to automatically ingest the scheduled recordings. The possible options are: disable the automatic ingestion (none), ingest immediately after the recording (immediately) or ingest nightly all the recordings of the previous day (nightly). Defaults to 'none'. *(none|immediately|nightly)*
* {{host}}: Matterhorn server URL.
* {{username: Name of the Galicaster unit. Defaults to the host name as defined in the OS, prepended by "GC-" if it is a Galicaster Class or "GCMobile-" if it is a Galicaster Mobile.
* {{password}}: Password for the account used to operate the Matterhorn REST endpoints service.
* {{hostname}}: Custom denomination of the galicaster unit. By default it's obtained from de operative system.
* {{workflow}}: name of the workflow used to ingest the recordings.
* {{workflow-parameters}}: pairs of parameter and value (parameter:value) to be parsed on the Matterhorn workflow, separated by semicolon.

Example:
{code:none}
[ingest]
active = False
manual = nightly
scheduled = immediately
host = http://fakeadmin.matterhorn.com:80
username = matterhorn_system_account
password = CHANGE_ME
workflow = full

{code}

{anchor:config_allows}
h6. Section {{allows}}

* {{manual}}: Allows full manual control of the recordings. ({{True\|False}})
* {{start}}: If {{manual}} is false, recordings can be started manually. ({{True\|False}})
* {{stop}}: If {{manual}} is false, recordings can be stopped manually \-also the scheduled ones. ({{True\|False}})
* {{pause}}: Allows pausing a recording \-independently from the value of {{manual}}. ({{True\|False}})
* {{overlap}}: If activated, a manual recording takes priority over a scheduled one, meaning it will not stop when the scheduled one should start. Otherwise, the manual recording will be stopped and the scheduled one started.({{True\|False}})

Example:
{code:none}
[allows]
manual = True
start = False
stop = False
pause = True
overlap = False

{anchor:config_profiles}
h5. Profiles

Profiles are a new feature added on Galicaster 1.2.0. Each profile contains a group of tracks that will be ran together. The syntax of a profile it's simple.

* On the data section, a name to identify the profile is set.
* The order on the track list determine the position on the preview, the first one on the list will be the first from left to right.

An example with mock devices:
{code:none}
[data]
name = Example

[track1]
name = Static
device = videotest
location = default
file = SCREEN.avi
flavor = presentation
caps = video/x-raw-yuv,framerate=25/1,width=640,height=480
pattern = 1
color1 = 4294967295
color2 = 4278190080

[track2]
name = Bars
device = videotest
flavor = presenter
location = default
file = CAMERA.avi
caps = video/x-raw-yuv,framerate=25/1,width=640,height=480
pattern = 0
color1 = 4294967295
color2 = 4278190080
{code}

Each profile can have one or many tracks, usually from 1 to 4 (two videos and two audio streams). You can shift between profiles on the profile menu, clicking on the button below Recorder, on the welcome page.

When you change a profile it's automatically loaded. If anything goes wrong, you will receive a message on the Recorder area.
You can try another profile any time you want, without leaving the program. You have to leave the program to edit any profile, if you have knowledge to do so
