The Goom plugin is based on the Goom visualization code from the Goom homepage found at: http://ios.free.fr/?page=projet&quoi=1 Like the original library so is the Goom plugin available under the LGPL license This is based on goom2k4 with changes to plugin_info.c and mmx.h to use liboil for CPU detection and GStreamer-specific ifdef's for architecture detection.
