    一、编码流程

    1、encmain.cpp:

      // 创建cTAppEncTop类,解析输入的配置函数,设定时间相关的参数
      int main(int argc, char* argv[])  
      {
        ...

        cTAppEncTop.encode();  // call encoding function

        ...

      }

    2、TAppEncTop.cpp:

      /**
       - create internal class
       - initialize internal variable
       - until the end of input YUV file, call encoding function in TEncTop class
       - delete allocated buffers
       - destroy internal class
       .
       */

      // 对编码器所使用的几个对象进行初始化,分配YUV数据缓存,循环读取YUV文件

      Void TAppEncTop::encode()

        ...

      }

    6、TEncCu.cpp:
