+GStreamer Base Plug-ins is a well-groomed and well-maintained
+collection of GStreamer plug-ins and elements, spanning the range of
+possible types of elements one would want to write for GStreamer.
+It also contains helper libraries and base classes useful for
+writing elements. A wide range of video and audio decoders, encoders,
+and filters are included.

+Subject: videoscale: fix negotiation after addition of new formats and methods
+
+Now that we no longer support all methods for all formats, we
+need to cater for that in the transform function: we can't
+transform formats not supported by the currently-selected
+mehod.
+
+make check, folks. It's da bomb.
