The short answer is yes you must keep the rtsp socket open.
If the stream is over TCP the RTP packet travels over the socket of the RTSP session. If the stream is over UDP the socket is used by the server to know if it should keep sending packet to the client because the UDP packet transmission does not have any feedback if the client is still alive.
Edited:
I think the answer marked correct is actually incorrect. In general, the cameras implement the RTSP protocol version 1 not version 2. In the 10 years that I have of experience in video surveillance systems I have found that several models of cameras stop sending RTP packets after closing the RTSP session socket .

I think you might be right?! The question is does the RTSP protocol demand it, but you hit more at the heart of my question. I see that it by default doesn't require it, but in my specific application your behavior is what i continue to experience. While it may not be "required" some implementations of firmware assume you'll keep the RTSP session open.
