The Galicaster Project is an open-source initiative to provide flexible, state-of-the-art solutions for recording educational multimedia contents like lectures and conferences.

Main Goals

Our main goal is the creation of multiple open-source applications adapted to different scenarios and equipment. So far, two Galicaster applications have reached a mature state of development: Galicaster Class and Galicaster Mobile.

  • Galicaster Class (GClass) is designed to be in a classroom environment with a basic control set and a tactile interface. It works automatically but some manual actions are available to the lecturers: muting the audio, pausing the recording and manual starting and stopping if desired.

  • Galicaster Mobile (GMobile) is 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.

Another goal pursued by the Galicaster Project is the creation of end-to-end, complete working solutions for recording educational multimedia contents, focusing not only on capturing affairs, but also on providing connectivity with the publishing systems and the distribution channels.

Key Features
  • Live visual feedback of what is being recorded, including a vumeter for audio monitoring.
  • Remote monitoring of the recording, via VNC.
  • Finished recordings can be browsed, played, deleted or downloaded from Galicaster as a single "zip" file (MH-Media package format)
  • Recordings can be ingested directly to an OC-Matterhorn core for publishing.
  • Recording may be triggered automatically or manually.
  • Basic control of the recording in-place (start, pause, stop…)
  • It is compatible with Matterhorn scheduling system
  • Touchscreen interface.

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.


All branches of Galicaster are virtually adaptable to any publishing platform since they keep all the recording metadata and video and audio tracks are recorded separately. Proof of this is the combined [Galicaster and Opencast Matterhorn] installation which will soon go into 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.


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

Designed to be Compatible with Opencast - Matterhorn

Galicaster integrated on Access Grid

September 29th 2011

Today we are starting to record the Master course in Nutrition in the Access Grid facilities at the University of Vigo's main campus. 8 hours of lectures would be recorded weekly, and by taking advantage of the adaptation between Galicaster and the Access Grid technology, presenter, presentation and audio are simultaneously captured. The media is published using a Matterhorn 1.2 Core and it is only accessible to the students registered on the master course.

Galicaster Class almost ready

September 12th 2011

After a long hard-working summer we are almost ready to install our first Galicaster Class (old) prototype.Two classrooms on either facuties of the University of Vigo will host a GClass capture agent connected to an Opencast Matterhorn server.

As soon as posible some demos would be published for you to have a better idea of what GClass is.

Currently on development - working on the beta version

June 13th 2011

After the success first trials we are working hard on publishing our first beta version. Currently we are improving our video and audio control and solving some issues with the user interface.

If you want any other information or you are interested on being a beta tester contact us. Keep posted!

First trials - alpha version succeeded

May 22nd 2011
