Would CAR work for what you are trying to do? You could limit certain
traffic defined by an access list (multicast destinations except for
224.0.0.5/6) to whatever rate you wanted.

Subject: Re: Control Multicast Traffic
Then how can I control multicast storm but without affecting the ospf
process assuming the following configuration:
R1 --- Cat35 (vlan 4) ---- R2.
f0/1(vlan4) --> R1
f0/2(vlan4) --> R2
f0/3-4(vlan4) --> other routers
Thanks

When you reach the limit for multicast, all traffic (broadcast + unicast
too) will be dropped until the mcast traffic falls below the configured
level:

When the rate of multicast traffic exceeds a set threshold, all incoming
traffic (broadcast, multicast, and unicast) is dropped until the level
drops below the threshold level. Only spanning-tree packets are
forwarded. When broadcast and unicast thresholds are exceeded, traffic
is blocked for only the type of traffic that exceeded the threshold.
