EPG not found or mismatched for some channels via DVB-T2

[mvallevand]

Turns out the next issue is going to be a little harder to track down

NextPVR is correctly reporting messages like this on all channels on 474 Mhz

2025-09-16 19:49:11.492 [VERBOSE][49] Unable to find any channels with mapping: 51:22:10254:8572

Meanwhile the Linux drivers that NextPVR uses reported it as this

2025-09-16 19:32:58.746 [VERBOSE][23] key:22:10252:8572 channel:RAS Das Erste HD

So with strict mapping 10252 will not match 10254. The standalone utility in Linux dvbv5-scan also reports the same as NextPVR so it appears that it is a Linux library driver issue.

Code:

[RAS Das Erste HD]
        SERVICE_ID = 22
        NETWORK_ID = 8572
        TRANSPORT_ID = 10252
        VIDEO_PID = 2201
        AUDIO_PID = 2202 2203
        PID_06 = 2205
        PID_05 = 2207
        FREQUENCY = 474017542
        MODULATION = QAM/64
        BANDWIDTH_HZ = 8000000
        INVERSION = AUTO
        CODE_RATE_HP = 3/4
        CODE_RATE_LP = AUTO
        GUARD_INTERVAL = 1/8
        TRANSMISSION_MODE = 8K
        HIERARCHY = NONE
        DELIVERY_SYSTEM = DVBT

OK I think I was able to make adjustment in DeviceHostLinux, let me now how this works.

Thank you very much, this new DeviceHostLinux version might have solved the issue. At least now I can see EPG information for the respective channels (have to check, that it is correct, but it looks like it).

Thanks a lot!

Thanks for all the help. Things look ok but let us know if you find issues. I expect the full 7.0.3 release shortly if we don't hear anything.

Cheers, so for future versions or if I ever had to reinstall NextPVR I could simply install version 7.0.3, is that correct? Or would I have to replace the DeviceHostLinux file as described here?

The change will be included in all future releases, so you don't need to replace DeviceHostLinux.

Awesome, thank you very much!

Hi,

I have seen the new version 7.0.3.250920 has been released. I was just wondering, since I did the testing with the pre-release version. Can I just update to the release version as usual, or is there any clean-up I have to do before.

For the testing I also deleted all the channels from my tuners and used the following code to save the config and system folder.

Code:

#stop the server
sudo service nextpvr-server stop
#backup your system program folder
sudo mv /opt/nextpvr/system  /opt/nextpvr/system702
# zip up your configuration in case you need to repeat a test.
zip ~/npvrdata /var/opt/nextpvr/npvr.db3 /var/opt/nextpvr/config.xml
# install the beta
sudo nextbuild=beta dpkg -i nextpvr-helper.deb

Can I replace the system folder with my old one and the config files with the previous ones? Or is that not recommended, i.e. should I create my channels and favourites from scratch? The main work I would have to do is to delete the channels I do not need (to avoid loosing time for EPG searches for channels I don't use) and to order them according to what I am used to.

[mvallevand]

It depends. For the system, it won't make a difference what you do, Sub will releasing be a new deb installer that backs up the 7.0.2 system folder but you manually did that.

For the configuration, if 7.0.2 npvr.db3 has a channel list you' like better than the beta you can go back to it, but you still will need to rescan to get the new strict IDs.

Cheers, thanks for the explanation!
