场景
testrtspclient通过rtp over tcp 跟服务器进行连接，在进行几分钟的通信之后，出错如下：
envir() << "RTCPInstance error: Hit limit when reading incoming packet over TCP. (fNumBytesAlreadyRead ("
<< fNumBytesAlreadyRead << ") >= maxRTCPPacketSize (" << maxRTCPPacketSize
<< ")). The remote endpoint is using a buggy implementation of RTP/RTCP-over-TCP. Please upgrade it!\n";
