Hi. Iptv plugin use "frequency" as unique enumeration for channels. In readme is a some limitations:
-Multiple channels with identical service id should have frequency difference of 4 or greater. It's recommended to use frequencies in decades (10, 20, 30, 40, ...) for all IPTV channel entries. I try use iptv channel with this parameters: ANIMAL PLANET;DSV:20170:S=1|P=1|F=UDP|U=188.8.131.52|A=2020:I:0:1101=2:1102=rus@4:0:6 52,634:1100:0:0:0 Ip address is 184.108.40.206 and I set frequency 20170. Frequency = 20170, and "int cChannel::Transponder(void) const" function return 20, but not 20170. In result, PAT changing pids on incorrect channel, because function "cChannel *Channel = Channels.GetByServiceID(Source(), Transponder(), pmt.getServiceId())" in "void cPatFilter::Process(u_short Pid, u_char Tid, const u_char *Data, int Length)" works incorrect too. I suggest to write a limitation for max frequency = 20000 in iptv readmy, or change int cChannel::Transponder(void) const, so it works correct with iptv plugin (and may be other plugins).
