+          adding ffmpegcolorspace element supplied by Ronald after cleaning
+          up and pulling in the right bits of upstream source. 
+          I'm sure a better C/compiler wizard could do some cleaning up (for
+          example use GLIB's malloc stuff), but as a first pass this
+          works very well
