说明：  本程序主要四大功能特点: 1、继承了 YUVViewer 可以同时打开多窗口的特点； 2、继承了 Elecard YUV Viewer 可以进行两幅图像对比的特点； 3、增加了宏块信息显示功能； 4、增加了两图对比时同步帧跳转功能： 例如对于错误码流，不同的错误隐藏算法可能造成解码序列长度不同，这时要比较两个序列就很不方便。而该功能正是为了解决这个问题，即以另一序列的显示图像为标准，在当前序列中寻找与其完全相同的图像。
(Four main features of this procedure: 1, inherited YUVViewer can also open multiple windows of the characteristics 2, inherited Elecard YUV Viewer can be characterized by comparing two images 3, an increase of the macro block information display 4, increasing When comparing the two plans simultaneously frame jump function: for example, the error stream for the different error concealment algorithm for decoding the sequence length may result in different time sequences to compare two very inconvenient. And the function is precisely to solve this problem, that is another sequence of display images as the standard sequence search in the current image with exactly the same.)
