Tvheadend sees muxes but no services

Added by Howard Lowndes about 7 years ago

The setup is a Raspberry Pi 3 running OSMC 2017.08-1 kernel 4.9.29-9
At the moment I am pulling DVB-T signals off a Mythtv backend over nfs and all works fine and I have 5 muxes detected (10 are available but they are duplicates, 5 on VHF and 5 on UHF).
I want to dump the Mythtv backend and use tvheadend on the Raspberry Pi.
I am using generic decoders with RTL2832U chips. dmesg shows the decoders as being fully installed [attached edited].
When I run w_scan on a decoder it sees most of the frequencies that I would expect but doesn't find any data [attached unedited].
Thoughts please.
TIA.

Is there any chance I can get a follow up on this problem

if you play the muxes from Tvheadend in VLC are you able to see the services?

I shifted the adaptor over to a Linux laptop with VLC and the OS find the device OK:

When I start up VLC and go Media->Capture Device->TV Digital and select DVB-T2 then Play, nothing happens, but selecting DVB-T then Play, VLC scans the entire spectrum and comes up with zip, zero, zilch then just restarts the scan. I have tried this with both an external and an internal aerial connected.

When I run w_scan -ft -cAU then the frequencies I would expect to see are:
184.5
191.5
212.5
219.5
226.5
529.5
536.5
543.5
550.5
557.5

but the output from w_scan with an external aerial is:

Done, scan time: 05:19.144

Given that the low frequency tower is about 20km line of sight and the high frequency tower is 2km line of sight, and that I have no problem tuning either tower with a conventional TV, this problem is mystifying.

TIA,

You can try with dvbsnoop

only correct scan data (freq, qam )is for 557,5 mhz

is there different firmware for tuner?
