Ruby bindings for GStreamer are now part of the Ruby-GNOME2 project. It was necessary since GStreamer is based on GLib, and Ruby-GNOME2 hackers provide a very nice wrapper for it. Also, since GStreamer is now part of the GNOME project, it was meaningful that we integrate Ruby-GStreamer in Ruby-GNOME2.
Ruby-GStreamer became Ruby/GStreamer.
Ruby/GStreamer is now released under LGPL, to fit Ruby-GNOME2 admission requirements.
See the ChangeLog (may be 24 hours late, thanks SourceForge!).
You can grab Ruby/GStreamer in two ways from this page:
