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.

This optionally depends on opencore-amr, libdvdcss, libmpeg2, twolame, 
and x264.
