h4. Custom GStreamer BIN

h4. Custom device plugin

This feature is meant for advanced users. Defining a custom bin allow to test new sources within Galicaster.

...

{code:none}

name = custom
location = default
file = CAMERA.avi
device = custom
flavor = presenter
active = True
pipestr = videotestsrc name=gc-custom-src is-live=true ! video/x-raw-yuv,framerate=10/1,width=640,height=480 ! tee name=tee-vt ! queue ! ffmpegcolorspace ! xvimagesink sync=false async=false qos=false name=gc-custom-preview tee-\

The elements source (src), valve and sink must be named as in the example, to allow the program to recognize them.

{anchor:logger}
h4. Configurable logger

In this version, specifying where the logs are stored, the minimum level showed and whether the logs rotate or not is very simple:

{code:none}
[logger]
path = /var/log/galicaster/galicaster.log
level = DEBUG
rotate = True
{code}

{section}
{column:width=40%}
{note:title=Be Careful}
Make sure Galicaster has write permissions in the directory where the logs are to be kept.
{note}
{column}
{column:width=60%}
{column}
{section}

Galicaster can also use the system log (syslog) instead:

{code:none}
[logger]
use_syslog = True
{code}

{anchor:rest}
h4. REST Plugin

The REST endpoint plugin for Galicaster is a module to provide an experimental endpoint interface to access some parameters and features of Galicaster.

If activated, the REST plugin will response in the localhost address through the 8080 port.

Current endpoints include:
* /*state* : show some state values,
* */repository* : list mp keys ,
* */repository/:id* : get mp manifest (XML)
* */metadata/:id* : get mp metadata (JSON)
* */start* : starts a manual recording
* */stop* : stops current recording
* */operation/ingest/:id* : Ingest MP
* */operation/sidebyside/:id* : Export MP to side-by-side
* */operation/exporttozip/:id* : Export MP to zip
* */screen* : get a screenshoot of the active

Activating this plugin as simple as:
{code:none}
[plugins]
rest = True
{code}

_To test the plugin we recommend using add-ons on your browser to visualize JSON data._

{anchor:metadata}
h4. Galicaster 1.3 Metadata Treatment

Before Galicaster 1.3, only some metadata was collected, specially on Series metadatata where only _name_ and _identifier_ where preserved.

After study and discuss the current situation on metadata regarding Matterhorn and Galicaster we've made the following modifications on the behavior on Galicaster's side:

* All metadata is captured, both in episode and series.
* If custom parameters are included on the Matterhorn schedule they are conserved through Galicaster.
* The only parameters that can be modified are: title, presenter, language, description and Series
** A change on Series makes all series parameters change at once
* Empty parameters are not included on the files.

Unfortunately Matterhorn overwrittes the metadata of a returning mediapackage, so modifications have to be made in order to preserve any changes on the capturer. However, if a mediapackage is ingested a second time the metadata - but the identifier - will be preserved.
