- * 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/

-/* And this is the header that came with the RoQ video decoder: */
-/* ------------------------------------------------------------------------
- * Id Software's RoQ video file format decoder
- *
- * Dr. Tim Ferguson, 2001.
- * For more details on the algorithm:
- * http://www.csse.monash.edu.au/~timf/videocodec.html
- *
- * This is a simple decoder for the Id Software RoQ video format. In
- * this format, audio samples are DPCM coded and the video frames are
- * coded using motion blocks and vector quantisation.
- *
- * Note: All information on the RoQ file format has been obtained through
- * pure reverse engineering. This was achieved by giving known input
- * audio and video frames to the roq.exe encoder and analysing the
- * resulting output text and RoQ file. No decompiling of the Quake III
- * Arena game was required.
- *
- * 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/
