multicast multiple source address

I'm seeing multiple souce sending traffic to 238.1.1.250 group. i've a client set to receive traffic for 238.1.1.250. would all of these source be sending same traffic to 238.1.1.250? how do i find out from which client I'm receiving traffic? is there any command on router to find it out?

 

gw#sh ip pim rp
Group: 238.1.1.250, RP: 10.10.1.1, next RP-reachable in 00:00:15
Group: 238.1.1.250, RP: 192.168.2.3, v2, uptime 6w0d, expires 00:02:56

gw#sh ip mroute | i 238.1.1.250
