 * Welcome to vpar_blocks.c ! Here's where the heavy processor-critical parsing
 * task is done. This file is divided in several parts :
 *  - Initialization of the lookup tables
 *  - Decoding of coded blocks
 *  - Decoding of motion vectors
 *  - Decoding of the other macroblock structures
 *  - Picture data parsing management (slices and error handling)
 * It's a pretty long file. Good luck and have a nice day.
