How do I scan for channels?

[burrows]

Hi,

My environment:

• Debian 10 (Buster)
  
• Tuner card TBS-6902
  
• Satellite Astra-28.2E
  

Whenever I click "Scan Channels" via the web interface, nothing is found. How do I perform a full scan without knowing any frequencies whatsoever? TVHeadEnd scans all available channels and streams them perfectly, but I can't do the same with NextPVR v5.

NextPVR detects my twin tuner card:
[ATTACHMENT NOT FOUND]

I'm confused about what numbers to put in the following three boxes:
[ATTACHMENT NOT FOUND]

Regards,
Burrows.

P.S.

I can't wait for the stable release on Linux so keep up the exciting work!

Using Raspian Buster I recently talked to sub about a scanning issue where it only scanned the first channel

From the command line what do you get with

Code:

./DeviceHostLinux -device:adapter0 -type:DVB-S -scan:/usr/share/dvb/dvb-s/Astra-28.2E

Code:

$ ./DeviceHostLinux -device:adapter0 -type:DVB-S -scan:/usr/share/dvb/dvb-s/Astra-28.2E
11:49:51:355 [DEBUG] Scanning from /usr/share/dvb/dvb-s/Astra-28.2E

Did anything get written to stderr?

Did anything get written to stderr?

No, that was the whole output (stdout). The following directory DOES NOT exist:

/home/burrows/NPVR-data

Instead, the following directory DOES exist:

/home/burrows/.NPVR-data

Is that a bug or intended behaviour?

[mvallevand]

Sub explained that is how running the CLI like this works. If you create NPVR-data do you get more info?

My last post is awaiting approval from the mods. It contained `Segmentation fault` after the scan.

[mvallevand]

It might have a URL in it copy what you want into a txt file and attach it.

I still had tvheadend running, sorry. After stopping tvheadend I executed the same command again. Attached is the output.

[mvallevand]

Yes that is basically what I expected. I think there is something going on with handling newer version of libdvbv5 shspvr also reported something similar to what you and I are seeing.
