I think you mean “runtime RTSP *server* failure” here…

There’s no way (in any application-level code) to detect *immediately* when a
server fails or when an Ethernet cable gets disconnected, because the TCP
connection (for RTSP) can remain in existence (from the client’s point of view)
long after this happens.
What you *can* do, however, is have the client periodically (e.g., every 1
second or so) check how many packets have been received. If you ever find that
the number of received packets has not changed (since the last time that you
checked), then you know that the server has stopped transmitting.
Note, for example, how we implement the “-D <maximum-inter-packet-gap>” option
in our “openRTSP” RTSP client application; see
