Tuning problems on pi4

[TauNeutrino]

Hi,


first of all: at the moment i am running newst nextpvr version on my windows server backend with the DVBSky s960 CI Card (which works flawlessly).



--> Now, I just tried to use nextpvr as a backend on my pi4 with the latest raspberry pi os:



Therefore, I installed nextpvr using the deb provided in this thread: https://forums.nextpvr.com/showthread.php?tid=59576



so what i basically did is:

Code:

curl https://nextpvr.com/nextpvr-helper.deb -O

sudo apt install ./nextpvr-helper.deb --install-recommends

I also installed the firmware for my card (dvbsky s960) via

Code:

cd ~
wget http://www.dvbsky.net/download/linux/dvbsky-firmware.tar.gz
tar xfvz dvbsky-firmware.tar.gz
cd dvbsky-firmware
sudo ./copy-firmware.sh

which results in

Code:

The Tuner card is found in the nextpvr setting page!



--> I did a first scan on ASTRA 19.2E and added some of the channels found to my channel list. The tuning and the search seems to work (at least some channels are found!



However, as soon as I try to switch to one of the channels (from a frontend pc with the browser or kodi) i get an error msg:



Here is the output of service nextpvr-server status

Code:

Apr 04 23:37:10 raspberrypi systemd[1]: Started NextPVRServer.
Apr 04 23:49:37 raspberrypi server.sh[608]: ERROR    frequency: 8006.25 MHz is out of LNBf range

Apr 04 23:49:37 raspberrypi server.sh[608]: ERROR    Can't find device

I actually dont know where the frequency 8006.25 MHz is comming from since I tried to switch to

Code:

Das Erste HD
at f = 11494 (h) @ 22k

I im serioulsy wondering how to fix this (since i tried out various stuff now for like 4 hours....). However I am very new to linux so might just be something obvious....




Any ideas?

From the release notes CAM/CI is only supported on Windows.

I am aware about this but also switching to channels without encryption are causing the same issue! The channel mentioned above is one of them. Basically tuning to any channel does not work.

[mvallevand]

Perhaps completely disable CAM/CI and rescan. If that does work try to use dvbv5 tools like dvbv5-zap and dvbv5-scan to see if they work manually. NextPVR is only using what is reported to it

How do I disable Cam/CI? Can this be done in the nextpvr settings?

[mvallevand]

No idea. Did you try the manual modes I asked about?
