Myth 29 - channel scan finds no channels when previously worked.

Post by briggella » Thu Jun 25, 2020 10:11 am

My first and previous post was two years ago with a similar problem when I was installing this system. After a few tweaks it has worked reasonably well since then. I am running mythtv version: fixes/29 v29.1-13-g329c235 on a Ubuntu 18.04 base with a HVR 5525 DVBS/DVBT PCIe card, an HVR NOVA TD500 dual tuner card and a HVR 2215 PCIe card. These provide 1 satellite and 5 DVB-T tuners of which 4 of the DVB-T tuners have been activated.

I had a High gain aerial fitted 2 years ago as we are in a weak signal area which is bounced off four local dormant volcano and has been very good until 10 days ago when it largely disappeared and the picture turned to custard. Satellite has been fine. A new dual multiphase aerial has been fitted which has been fitted but I need to retune all my channels to ensute that they are properly tuned in. However when I do this, no channels are found. I have changed myriads of settings but nothing helps. I have run w_scan and all the channels appear and the results confirm that my frequency settings in the transports are correct. I have gone through permissions, adaptor loading order, firmware loading, I have checked all my logs for errors and done a debug log for the channel scanning and found nothing. I am certain that the frequencies transport settings are correct. I am now stumped and would appreciate any other ideas. My system is working but cannot retune so I am loathe to wipe all my tuners and reinstall as I do not wish to risk losing the channels I have already got. if they do not scan.

I have run out of ideas to try. I have tried all permutations of the transports. Everything else seems correct. I would be grateful for any thoughts.

Have you tried to do a scan with the other adapters, not only with adapter3?

Yes - I have also tried adapter2. The Si2168 tuners do not display signal strength, I believe due to a bug in the Linux Kernel, so I am limited to using the DVB-T tuners rather than the T2 tuners. They still work for watching TV but show signal strength as 0% which is not helpful. I haven't tried the satellite as there has been no problem with the picture quality with that.

If a tuner works with w_scan it should also work with mythtv.
If mythbackend can make recordings with a certain tuner then mythtv-setup should be able to do a channelscan with that tuner. But of course only when the mythbackend is not running.

The log shows that you did a "Full Scan". You could also try "Scan of existing transports" if you have not done that yet.

I do not see low-hanging fruit...
Can you please provide the contents of database tables dtv_multiplex, capturecard, videosource and channel.

This can be done with the following commands:
mysql -u mythtv -p mythconverg -vv -se "select * from dtv_multiplex;"
mysql -u mythtv -p mythconverg -vv -se "select * from capturecard;"
mysql -u mythtv -p mythconverg -vv -se "select * from videosource;"
mysql -u mythtv -p mythconverg -vv -se "select * from channel;"

Having this in an attachment is preferred.

OK now things get interesting.

By way of clarification, My original terrestrial transports were called Freeview for DVBT and Freeview2 for DVBT2 catds. In order to avoid any complications with these, I created new transports of Freeview-DVBT and Freeview-DVBT2 to do fresh scans and if they setup correctly, I would delete the old transports and use the new ones in their place. This is why there are more transports than seems necessary in the reports.

The bit that is interesting though is that I ran the Scan of existing transports and they scanned correctly and found 12 channels. The full scan found nothing. So now I am really confused.

Sorry but strange things seem to be happening with file attachments.

Have not done yet a full analysis, that will be the weekend, but already a few remarks.

The "scan existing transports" was done with adapter 2.
Try a "Full Scan" with adapter 2 . Also, in the "Full Scan" selection, press the right arrow and then you can select your country. Make sure it is correct, maybe you have selected Australia instead of New Zealand. The list of frequencies to scan for is country-dependent.

Yes it must be the country selection. For example, the 562MHz that is present in your dtv_multiplex table and that is found by w_scan is present in the list of frequencies scanned when set to New Zealand but it is missing from the list of frequencies scanned when set to Australia.

It could be considered to be a bug that the default setting for this in MythTV is Australia, independent of the physical location. However, it is nice that MythTV is capable of operating without Internet.

A practical solution can be that there is no default location and that an explicit choice must be made before the Full Scan is actually done.

Actually the New Zealand selection doesn"t seem to work. I couldn't select NZ in w_scan and had to use default which turned out to be DE. The New Zealand selection in myth often doesn't work too so I have always left it at default. We are used to being forgotten about at this end of the world but we work around it. We sometimes don"t appear on World maps. :-)

I'll try the Full scan with a couple of countries inc NZ

Something has gone wrong... this are two Australian scans. After making the country selection you have to use the left arrow key to get back to the Full Scan otherwise the selection is lost and the default is used again.
Selecting New Zealand, Germany or Netherlands should work.

If you want to have something to read while waiting for the scan to complete you can always start reading the Wiki page for Channel Scanning in page https://www.mythtv.org/wiki/Channel_Scanning which is for v31 but mostly correct also for older versions.

w_scan is deprecated.
Even if you build it from source (which you must), I recall it does not work with T2 & later T2 tuners.
It may not work with current kernel v4l2-dvb media drivers.

Your new ganged array antenna is much better for dvb-t/t2 than directional hi-gain as dvb-t/t2 modulation scheme handles multipath well.

The best zap & scan tool is the latest dvb5-tools. (*buntu libdvbv5 & dvb-tools)
http://ppa.launchpad.net/libv4l/development/ubuntu
This is (or was) mandatory with newer T2 & S2 tuner cards.

dvbv5 uses new/different format. Have attached my files from around time of a new T2 tuner & Kordia UHD trials.
And attached MythTV scanner output; version master at about Feb/Mar 2019.
My region (& frequencies) are not same as what is listed in your logs.
MythTV scanner (& NZ selection) has always worked for me over last 10+ years.

Sorry about that - should have read it more carefully. I changed the Country setting in the Video Sources and didn't realise that the channel scanning had a separate setting that would override it. Once I followed your instructions, the Full scan worked for Tuner 2. It didn't work for the T2 tuners but I think this is because they use a Si2168 chip and the signal strength is reported as 0%. This is a different issue that I shall look into and post back on a different thread if I get stuck. I consider the original problem solved now.

log attached of DVT scan

Thank you for your help and as I ever I have learned something new.

Glad that it is working! You could consider moving to v31/fixes or master as this has now support for dvbv5. Which might be needed for your new tuner.
