Config Option: Source Backfeed Multicast IP

[anthonyeden]

From emails with John Hengesbach. He wants to be able to put a Backfeed Multicast IP address into the 'LWNumber' field. This proposed change will fix this (and he has it running himself), but I need to do some testing myself before merging it into the main app.

Original code at line 183-193:

           self.LWRP_Sources.append(
                {
                    "ButtonLabel": source['Name'],
                    "LWNumber": int(source['SourceNum']),
                    "LWMulticastNumber": AxiaLivewireAddressHelper.streamNumToMulticastAddr(source['SourceNum']),
                    "LWSipAddress": None,
                    "GPIOTriggers": [],
                    "DisableRouteChange": False,
                    "GPI_IndicationOnly": False,
                }
            )

Change it to this:

                # check to see if we have a "multicast" number in the
                # SourceNum field. If so, we can use this and calculate
                # the channel number to keep everybody happy.
                my_multicast_number = source['SourceNum'].split(".")
                if (my_multicast_number[0] == "239"):
                   # new way, use the SourceNum as the multicast number directly and reverse translate it to get the SourceNum
                   my_LWNumber =  AxiaLivewireAddressHelper.multicastAddrToStreamNum(source['SourceNum'])
                   my_LWMulticastNumber = source['SourceNum']
                else:
                   # original way...
                   my_LWNumber = int(source['SourceNum'])
                   my_LWMulticastNumber =  AxiaLivewireAddressHelper.streamNumToMulticastAddr(int(source['SourceNum']))

                self.LWRP_Sources.append(
                    {
                        "ButtonLabel": source['Name'],
                        "LWNumber": my_LWNumber,
                        "LWMulticastNumber": my_LWMulticastNumber,
                        "LWSipAddress": None,
                        "GPIOTriggers": [],
                        "DisableRouteChange": False,
                        "GPI_IndicationOnly": False,
                    }
                )
