h4. What is Galicaster?
{pop-away:metadata | comments | children | labels}


h5. Introduction

Galicaster is a Multistream Recorder and Player designed for mobile equipment without requiring a Internet connexion.
Galicaster supports recording in Matterhorn Mediapackage format, allowing us to modify metadata, rebuild old packages and build new ones. It also capable of send Mediapackage to ingest using the REST interface selecting a Matterhorn server.
The main goal of the Galicaster Project is to develop an open solution to provide *flexible, state-of-the-art solutions for recording educational multimedia contents*, like lectures and conferences. Galicaster project is supported by [TELTEK Video Research|http://www.teltek.es].

Other important feature of Galicaster is that we can control in realtime the parameters of the capture (proper recording, volume...), viewing in realtime what we are recording.
Galicaster capture solution is compatible with [OPENCAST|http://www.opencast.org/]. Galicaster-based devices can work as improved Matterhorn capture agents. They can register as a capture agent, thus being able to receive scheduled recordings and ingest the resulting mediapackages automatically.

Galicaster is been developed with GStreamer, Python and GTK using Python bindings PyGST and PyGTK, so it is a heavy application fully based on free software.

h5. Main changes on Galicaster 2.1.0

Future improvements would make Galicaster capable of associate schedule recordings and synchronize the recordings afterwards.
* Optionally set and report "Error" state to Opencast when the audio is below a threshold for longer than a set amount of time. (lowaudio plugn)
* Optionally set and report "Error" state to Opencast when the Galicaster HDD has less available space than a set threshold. (checkspace plugin)
* Send "Offline" status to Opencast before closing Galicaster (for OC > 2.3.0)
* Muxing a pulse audio soruce into a v4l2 video source to the same file. (multistream bin by @ppettit)
* Allow unlocking the Galicaster touchscreen through LDAP credentials. (lockscreen plugin)
* Added configurable tags to the mediapackage tracks through the profile configuration.
* Now in Galicaster a default series field for the mediapackage can be set for manual recordings.
* Bugfixing and code refactoring.

h5. Main Goal

Galicaster can be used as an automatic in-room recording solution for the classroom, keeping the professor informed and in control, or it can be used as a mobile unit, perfect for recording meetings and conferences.

Our main goal is the creation of *an aplication adaptable to different scenarios and equipment*. So far, two Galicaster configurations have reached a mature state of development:Fixed [Galicaster in the Class|Galicaster Class]room and [Galicaster for Mobile|Galicaster Mobile] operation.
* *Galicaster in the Classroom:* The idea is to deploy Galicaster in a classroom environment with a basic set of controls and a tactile interface. It works automatically but some manual actions are available to the lecturers, such as muting the audio or pausing/playing/stopping the recording if desired.
* *Galicaster for Mobile operation:* The idea here is to buid a a complete portable recording station, providing full control on the recorded media. Operators can get real-time feedback from cameras and microphones, so that they can react immediately against any unexpected situation, manage a repository with all the recording media, delete many recordings in a single operation, send and resend media to distribution channels, label tracks, etc.

h5. Versatility

Galicaster can be used alone, but it is *virtually adaptable to any publishing platform*, since it keep all the recording metadata and video and audio tracks are recorded separately. Proof of this is the combined [Galicaster and Opencast Matterhorn|Galicaster and Opencast, the best match] installation which is already in production at the University of Vigo.

Galicaster can be seamlessly integrated with a wide variety of environments: low-cost, flexible equipments; best-performance, customized installations; existing campus-wide infrastructures; media distribution platforms, etc.

h5. Technologies

Both applications are *based on Python and GStreamer*, both long term projects supported by large communities, ensuring their adaptability to most of the operating systems in the UNIX family. They can also be adapted to multiple kinds of hardware, expanding the possibilities to record with many types of devices such as laptops, HD Webcams, TV Cameras, video players, microphones ...
