Did you enable multicast snooping using the database?  The documentation
says:

     Multicast Snooping Configuration:
       Multicast  snooping  (RFC  4541) monitors the Internet Group Management
       Protocol (IGMP) traffic  between  hosts  and  multicast  routers.   The
       switch uses what IGMP snooping learns to forward multicast traffic only
       to interfaces that are connected to interested receivers.  Currently it
       supports IGMPv1 and IGMPv2 protocols.

       mcast_snooping_enable: boolean
              Enable multicast snooping on the bridge. For now, the default is
              disabled.
