# Well it worked sorta. I can now use videos as screen savers. gotta figure out a mute
and we can't seem to set the mplayer options in the mplayer_options attribute of the
file tag in the movie tag setup. I had to manually add this to the videoitem that i
got back from parse.

"""
A plugin to start a screensaver when freevo has been inactive in a menu
for a long time. There are 4 basic types and one of the types has two
subtypes. The types are xscreensaver, ssr, fxd, and script. The fxd type
has two subtypes: one for movies and one for slideshows. The
xsccreensaver type will only work if you are using an Xserver.
Here is an example xscreensaver type. You must provide the paths to
your xscreensaver and xscreensaver-command programs.
plugin.activate('freevoscreensaver',
args=('xscreensaver','/usr/bin/xscreensaver','/usr/bin/xscreensaver-command',))
Here is a script type example. Basically you write a start and stop
script you wish to use for a screensaver. This is a catchall for people
wanting a very specific saver with a specific config.
plugin.activate('freevoscreensaver',
args=('script','/usr/local/bin/screensaverstart','/usr/local/bin/screensaverstop',))
Shown below is and example of a ssr type of screensaver. It takes an ssr
file which refers to a bunch of pictures and displays them repeatedly.
plugin.activate('freevoscreensaver',
args=('ssr','/usr/local/freevo_data/Images/blah.ssr',))
Here is an image type fxd. Very similar to the ssr but taking the fxd
playlist approach to showing the images. This way you can set random if
you want it for example.
plugin.activate('freevoscreensaver',
args=('fxd','/usr/local/freevo_data/Images/saver.fxd','image',))
A video version of the fxd type screensaver. It repeatedly shows a movie
in a loop with no sound.
plugin.activate('freevoscreensaver',
args=('fxd','/usr/local/freevo_data/Movies/saver.fxd','video',))
