libtheora0 1.0-2.1 (i386 binary) in ubuntu karmic

 Theora is an open video codec being developed by the Xiph.org
 Foundation as part of their Ogg project (It is a project that aims to
 integrate On2's VP3 video codec, Ogg Vorbis audio codec and Ogg
 multimedia container formats into a multimedia solution that can
 compete with MPEG-4 format). Theora is derived directly from On2's
 VP3 codec; currently the two are nearly identical, varying only in
 framing headers, but Theora will diverge and improve from the main
 VP3 development lineage as time progresses.
