 * TODO:
 * 1, 任务栏图标在分析过程中闪烁，使用：pannelIcon = new QSystemTrayIcon(this);
                                  pannelIcon->setIcon(QIcon("tray.ico"));
      不同颜色图标交换切换即可；
      参考：http://blog.csdn.net/mingzznet/article/details/17202689
 * 2，HOVER事件，当移动到一些空间上面进行注释显示
 * 参考http://blog.163.com/zh_ch_0412@126/blog/static/16409046620124222494859/
 * 3, 建议加入一个mediainfo的功能，可以单独增加一个按钮显示播放了几个码流，
 *    每个码流的基本信息，比如分辨率，音视频格式，I/P，帧率之类的
