- * Creative YUV Video Decoder
- *
- * Dr. Tim Ferguson, 2001.
- * For more details on the algorithm:
- * http://www.csse.monash.edu.au/~timf/videocodec.html
- *
- * Code restructured, and adopted to MPlayer's mpi by A'rpi, 2002.
- *
- * 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...
