• [wxPython] (http://wxpython.org/download.php)
• [PyGame] (www.pygame.org/)
• [PyBluez] (https://pypi.python.org/pypi/PyBluez/)
• [Matplotlib] (http://matplotlib.org/)

How to change playback backend

If you want to use Pygame instead of VLC for video playback you need to change this line

     from player.VideoPresentationPlayerVLC import VideoPresentationPlayer

by this one

     from player.VideoPresentationPlayerPygame import VideoPresentationPlayer

at [VideoPresentation] (gvarvi/activities/VideoPresentation.py) module. Notice that Pygame only supports MPG video format (more info [here] (http://www.pygame.org/docs/ref/movie.html))
