* \brief : Interface of wels video processor class
*
* \date : 2011/01/04
*
* \description : 1. should support both C/C++ style interface
* 2. should concern with the feature extension requirement
* 3. should care the usage of "char"==>
* 1) value char : signed char/unsigned char
* 2) string char : char
