 *   \brief Interface to AVS Decoding.
 *
 * The interface for each algorithm module is defined as a comprehensive
 * table of function entries which is exposed by AVS Decoding. It implements
 * most of the functions defined in the AVS1-P2 Standard document except:
 * -# field coding
 * -# multi-slice structure
 * -# weighted prediction
 * -# eliminate fake initial code
