GStreamer Ugly Plug-ins is a set of plug-ins that have good 
quality and correct functionality, but distributing them 
might pose problems. The license on either the plug-ins or 
the supporting libraries might not be how we'd like. The 
code might be widely known to present patent problems.

gst-plugins-ugly will need the following dependencies:
gstreamer, liboil, gst-plugins-base. Buildscripts are available 
at slackbuilds.org
