//VIS MCU和VIS EP示例程序中利用nonstandard message来实现简单的会议控制
//开发者可以利用nonstandard message实现符合自己需求的会议控制,以及电子
//白板、文件共享等功能
//
//VIS MCU\VIS EP中使用的简单的控制命令如下
//  [前缀]                  含义
//  "MADD"     由MCU发给EP,告诉EP有人加入会议
//  "MDEL"     由MCU发给EP,告诉EP有人离开会议
//  "LIST"     由EP发给MCU,向MCU索取会议成员列表
//  "ROOM"     由MCU发给EP,告诉EP当前所在会议名
//  "ANNO"     通知信息,由MCU发给所有EP
//  "MSGA"     某个EP向所有人发话,由MCU发给EP
//  "MSGP"     某个EP发话给另一个EP,由MCU发给EP
//  "SMSG"     EP发话给另一个EP,由EP发给MCU,MCU然后转发成"MSGA"或者"MSGP"
//  "SETA"     EP发给MCU,告诉MCU要切换音频
//  "SETV"     EP发给MCU,告诉MCU要切换视频
