There are many open source efforts that run on desktop Linux that have been ported to the BeagleBoard. You can see many [http://www.angstrom-distribution.org/repo/ here]. One effort is [http://gstreamer.freedesktop.org/ GStreamer] a library for constructing graphs of media-handling components, or more simply, a open source multimedia framework.

== Getting Started ==

* Get the updated files from the git repository
beagle$ '''git clone git@github.com:MarkAYoder/BeagleBoard-exercises.git exercises'''
or if you've already git'ted them, make sure you have the most up to date versions.
beagle$ '''cd exercises'''
beagle$ '''git pull'''
beagle$ '''cd gstreamer'''

+The files beginning with '''v''' are video demos. There is a handy utility that puts the PS EYE in autogain mode.  You can run it by:
-  beagle$ '''./autogain'''  # This puts the PS EYE in autogain mode.
+  beagle$ '''../autogain/autogain'''  # This puts the PS EYE in autogain mode.
 # Try them and make a note about what each does.
