This is gnome-streamer, a framework for streaming media in GNOME.  The
fundamental design comes from the video pipeline at Oregon Graduate
Institute, as well as some ideas from DirectX.  It's based on plug-ins
that will provide the various codec and other functionality.  The
interface hopefully is generic enough for various companies (ahem, Apple)
to release binary codecs for Linux, until such time as they get a clue and
release the source.
