Bug #4647
Cannot receive DVB-T2 channels that are recievable with dvbv5-zap
0%
Description
I'm trying to use tvheadend in order to receive DVB-T2 channels in israel.
When I'm using w_scan or dvbv5-scan I can see the channel information and watch it with dvbv5-zap and mplayer.
However, when I'm setting new mux with the same settings (DVB-T2, Freq=562MHZ, bandwith=8MhZ),
tvheadend can see only the the radio channel and no the HD channels.
Using T230C USB dongle, ubuntu 16.04 kernel 4.4.0-96-generic, latest media_build drivers.
If required I can compile and check side branches of tvheadend.
Thanks,
Paradox.

Could you run 'w_scan -vvvvvv' and attach the log here?

Which mux data is in dump-tvheadend.ts ? Could you grab the mux TS stream from 538Mhz using the tvheadend's mux play link (in the mux grid)?

dump-tvheadend.ts contains mux data from 562 Mhz.
dump-tvheadend-538Mhz.ts contains mux ts stream from 538 Mhz mux.

Hi,
I played with dvbsnoop, and found that there is two Transport_stream_ID on the same mux:
Transport_stream_ID 2 that contains the radio channels that tvh finds.
Transport_stream_ID 3 that contains the missing tv channels.
In tvh mux configuration in "Transport stream ID" column there is the value 2.
Can I change the mux configuration to scan Transport_stream_ID 3 to recieves the TV channels?
Thanks,
Paradox.

Appearently 538Mhz mux is DVB-T2 mux with multiple PLP IDs. The w_scan utility forces PLP ID to zero to tune to TSID 3.
Could you confirm, if you set manually PLP ID to 0 - TSID (transport stream ID) is 3 ? (the mux config)
Also, could you check if radio PLP ID is 1 (or perhaps 255) ?

Thank you!!!
It worked PLP ID 0 gives me TSID 3 - and the TV channels, and PLP ID 1 gives me TSID 2 and it radio channels.
Thank you very much!
