How to setup default source interface for multicast?
There is a server 172.16.0.50 with udpxy. It converts multicast video to http unicast streaming to "R2" router clients. There is igmp-proxy setup on "R1".
My aim is remove igmp-proxy and link between "R1" and switch (the red wire on the diagram) and connect multicast source to the "SRV" directly (It may reduce cpu usage on R1)
So, i've used this cmd to receive mcast from "R1":
udpxy -a eth0 -T -p 8080 -S -c 40 -B 1Mb
Then i've tried to specify mcast source interface:
udpxy -a eth0 -T -p 8080 -S -c 40 -B 1Mb -m eth1
I added route to that interface, but udpxy hadn't received anything:
route add -net 239.200.0.0/24 eth1
Please tell me, what am i doing wrong?

The proper command to override it would beip route add multicast 239.200.0.0/24 dev eth1(but this might only be a part of the problem).

You should capture everywhere on R1 and on SRV, on each interface, multicast control traffic (IGMP, PIM ...) to see what might be different.
