Original commit message from CVS:
add initial version of gdkpixbuf loader for gtk that is capable of loading AVI and mpeg videos as GdkPixbufAnimation. I'm not sure if such a thing would be useful or too much trouble, so I'll throw it at enough testers to figure it out ;) We might want to disable it by defualt though in the future. (Currently there is not even a configure switch implemented to disable it.)
This includes a fix to not use GError in gstgdkpixbuf's typefind function and to only return GST_TYPE_FIND_MINIMUM when doing typefinding via gdk as this breaks quite a bit with the GStreamer loader installed.
