-/* And this is the header that came with the CYUV decoder: */
-/* ------------------------------------------------------------------------
- * Creative YUV Video Decoder
- *
- * Dr. Tim Ferguson, 2001.
- * For more details on the algorithm:
- *         http://www.csse.monash.edu.au/~timf/videocodec.html
- *
- * This is a very simple predictive coder.  A video frame is coded in YUV411
- * format.  The first pixel of each scanline is coded using the upper four
- * bits of its absolute value.  Subsequent pixels for the scanline are coded
- * using the difference between the last pixel and the current pixel (DPCM).
- * The DPCM values are coded using a 16 entry table found at the start of the
- * frame.  Thus four bits per component are used and are as follows:
- *     UY VY YY UY VY YY UY VY...
- * This code assumes the frame width will be a multiple of four pixels.  This
- * should probably be fixed.
- *
- * You may freely use this source code.  I only ask that you reference its
- * source in your projects documentation:
- *       Tim Ferguson: http://www.csse.monash.edu.au/~timf/
