LibreElec 9.2.5 and VDR 2.4.1 fails to scan channels on RPI4

ramya5606 · September 17, 2020 at 8:15 AM

Hi
I would like to know if anyone is facing this issue.

I have a pctv tuner and it works fine with LibreElec 8.2.5 (RPI3B) and also it worked fine when i build LibreElec from sources with branch libreelec-9.2 (RPI4)

But when i install LibreElec from the official channel (Raspberry Pi Imager), i cannot get the vdr plugin to work. Vdr configuration plugin does not show any details about the tuner.

Entries in the bottom panel are empty (ex: Tuner: , Frequency: and Channel: )

Following is the log from vdr process

Code

06:59:10 wirbelscan version 2018.11.04 @ VDR 2.4.1
06:59:10 using settings for 19.2 east Astra 1F/1G/1H/1KR/1L
06:59:10 frontend Montage Technology M88DS3103
06:59:20 leaving scanner

Do you have any suggestion? Is this an issue with vdr 2.4.1?

I have checked the status via restapi as well

http://192.168.1.179:8002/wirbelscan/getStatus.json

And seems like the api is working

Code

{"status":1,"currentDevice":"Montage Technology M88DS3103","progress":88,"strength":0,"transponder":"???:12552:VC56M2S0:S19.2E:22000:0:0:0:0:0:0:0:0","numChannels":0,"newChannels":0,"nextTransponder":0}

strange, do you still have the self compiled files ?

If so try to update to the self installed one if it happens there too.

Did you tried a clean install if it happens there too ?

Maybe just some strange behavior due the import of the old data.

Yes when i compiled from sources it works fine.

I stongly feel the firmware is corrupted.

I tried to check the same on raspberry pi OS and it failed initially (using kodi 19) but then tried the following and it is fixed.

I replaced the firmware lib from https://www.linuxtv.org/wiki/index.php…-S2_Stick_(461e) into /lib/firmware

and restarted device. I wonder what is the reason for the corruption of firmware lib in LibreElec.

Is there a way i can replace the firmware in LibreElec from commandline? the plugin way may not be working correctly

Copy it to /storage/.config/firmware and reboot.

its a mess
