Those messages indicate that the RTCP transmitter is using an erroneous implementation of RTP/RTCP-over-TCP.<br>
<br>
If the warning message is printed by your RTSP *client* (e.g., VLC), then it suggests that your RTSP server may be using a (very) old version of the “LIVE555 Streaming Media” software. If your RTSP server is using our software, then please upgrade it to use the latest version; see<br>
<a href="http://live555.com/liveMedia/faq.html#latest-version" rel="noreferrer" target="_blank">http://live555.com/liveMedia/<wbr>faq.html#latest-version</a><br>
If your RTSP server is an embedded system (such as a network camera) that uses our software, then note that it is a condition of the LGPL license that it be possible to upgrade its firmware to use the latest version of our software. Please inform the manufacturer of this server of this.<br>

If the warning message is printed by your RTSP *server*, then it suggests that your RTSP client may be using a (very) old version of the “LIVE555 Streaming Media” software.
