I have made an application using live media 555 library. In this application I'm receiving video stream </div><div>from my live media streamer application. Which in turns get stream from a dvd player. In my server application I'm creating rtsp server in my main program. And in same program I'm handling messages from anther client </div>
<div>application which sends me START_STREAM and STOP_STREAM messages. As per client applications messages my server application creates a session to receive stream from streamer application and also to send same stream to client application. For first </div>
<div>time START and STOP_STREAM works fine but when client sends START_STREAM next time, session is created by my server application but stream is not received by client application. My application shows following messages on screen.</div>
<div><br></div><br><div><div>MultiFramedRTPSource::doGetNextFrame1(): The total received frame size exceeds the client's buffer size (40). 1276 bytes of trailing data will be dropped!</div><div>sendRTPOverTCP: 1328 bytes over channel 0 (socket 932)</div>
<div>sendRTPOverTCP: completed</div><div>MultiFramedRTPSource::doGetNextFrame1(): The total received frame size exceeds the client's buffer size (19). 1297 bytes of trailing data will be dropped!</div></div><div><br>
</div><div><br></div><div><br></div><div><div>when I go though MultiFramedRTPSource::doGetNextFrame1() function in MultiFramedRTPSource.cpp file I come to know that </div><div>in this function "fNumTruncatedBytes" variable holds Truncated Bytes and comes into feature Second time when creating session.</div>
<div>I dont know how to handle this error.</div><div><br></div><div>Can anybody help?</div><div><br></div><div>Code is given below.</div></div><div><br></div><div><br></div><div><br></div><div><div>int StartRtspServer()</div>
