I suggest you to give a look at the Oil Runtime Compiler (ORC) and the
benefits it brings to GStreamer wrt SIMD instructions:
http://code.entropywave.com/projects/orc/http://gstreamer.freedesktop.org/wiki/GStreamerConference2010 (search for ORC)
you would get code not only optimised for SSE, but many of the most
common architectures in the wild.
