I don't think you need persistence for RTSP, as the tcp connection
on port 554 will remain open during the entire session. However, you
should use e.g. FWMARKs to tie the UDP and TCP part(s) of the session
together.

iptables -A PREROUTING -t mangle -p tcp -d 192.168.10.100 --dport 554 - 
j MARK --set-mark 84
iptables -A PREROUTING -t mangle -p tcp -d 192.168.10.100 --dport 8080  
-j MARK --set-mark 84
iptables -A PREROUTING -t mangle -p udp -d 192.168.10.100 --dport  
6970:7170 -j MARK --set-mark 84

virtual = 84
         real = 192.168.10.51 masq 30
         real = 192.168.10.52 masq 30
         service = none
         checktype = connect
         checkport = 554
         scheduler = wlc
         persistent = 60
         protocol = fwm
         emailalert = "root"
         emailalertfreq = 3600
