No, the problem is that old versions of the LIVE555 software (including the
version 2012.01.13 that this network camera uses) has bugs in the way that it
implements streaming of RTP/RTCP-over-TCP - that will trigger the “RTCPInstance
error: Hit limit…” error message that you’re seeing in the RTSP client. (There
is also a known security vulnerability in this old version of the code.) That
is why you should upgrade (notwithstanding the fact that LGPL license requires
that this be made possible).

Once you find out who to contact, then I suggest that you remind them of their
obligations under the LGPL; see
