Digital Devices Cine S2 V6, no channels

aks42 · January 29, 2023 at 4:47 PM

Hi,

I have a Digital Devices Cine S2 V6 dual-tuner DVB-S card installed on a custom built PC with Libreelec v10.0.0.4. It should work out-of-the-box but I cannot find any channels using TVHeadend.

Here is what works:

a) The PCI card is recognized. lscpi -v gives (only relevant part shown):

01:00.0 Multimedia controller: Digital Devices GmbH Octopus DVB Adapter

Subsystem: Digital Devices GmbH Octopus DVB Adapter (Cine S2 V6 DVB adapter)

Flags: bus master, fast devsel, latency 0, IRQ 136

Memory at df100000 (64-bit, non-prefetchable) [size=64K]

Capabilities: [50] Power Management version 3

Capabilities: [70] MSI: Enable+ Count=1/2 Maskable- 64bit+

Capabilities: [90] Express Endpoint, MSI 00

Capabilities: [100] Vendor Specific Information: ID=0000 Rev=0 Len=00c <?>

Kernel driver in use: ddbridge

Kernel modules: ddbridge

b) The kernel claims to have a driver

main:4004: FATAL: ***** NO USEABLE SATELLITE CARD FOUND. *****

Please check wether dvb driver is loaded and

verify that no dvb application (i.e. vdr) is running.

Note, vdr.bin is not activated here, I ensured this via:
# ps -Aef | grep -i vdr

1246 root 0:00 grep -i vdr

I'm a bit stuck. From the output of w_scan under opensuse I deduce that my hardware setup is OK. Both systems claim to have a driver for the card, the working one even an older driver. w_scan gives two items to check and I think both should be fine. I tried to load the Addon for Digital-Devices drivers and the default kernel ones without any change to this.

I assume that once I get w_scan working under libreelec then I probably can get tvheadend to work as well.

Any ideas how to go on with this?

To activate the 0.9.33-integrated driver select the LE Standard Drivers in the LibreELEC Module Drivers Addon and reboot.

aks42 · January 29, 2023 at 10:06 PM

Thanks for the reply. This did change the driver:

...

But the results with w_scan and tvheadend stay the same.

Update: Attached screenshots of what I selected now. Note that I am asked to reboot reach time I pick "LE default drivers". Don't know if that is normal or if that is an indication that something is not saved.

You may also need a proper firmware file. Maybe Linux4Media cineS2 DVB-S2 Twin Tuner - LinuxTVWiki ?

That is by design. The selected drivers are just set.

Publish logs by using pastekodi after trying to use the tuner and post the URL. Maybe there is something visible.

A bit of insight. I used strace on w_scan and found:

...

write(2, "Info: using DVB adapter auto det"..., 40Info: using DVB adapter auto detection.

) = 40

openat(AT_FDCWD, "/dev/dvb/adapter0/frontend0", O_RDWR|O_NONBLOCK) = -1 EBUSY (Device or resource busy)

openat(AT_FDCWD, "/dev/dvb/adapter0/frontend1", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter0/frontend2", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter0/frontend3", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter1/frontend0", O_RDWR|O_NONBLOCK) = -1 EBUSY (Device or resource busy)

openat(AT_FDCWD, "/dev/dvb/adapter1/frontend1", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter1/frontend2", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter1/frontend3", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/dev/dvb/adapter2/frontend0", O_RDWR|O_NONBLOCK) = -1 ENOENT (No such file or directory)

...

and then:

# lsof | grep frontend

1239 /storage/.kodi/addons/service.tvheadend42/bin/tvheadend /dev/dvb/adapter1/frontend0

1239 /storage/.kodi/addons/service.tvheadend42/bin/tvheadend /dev/dvb/adapter0/frontend0

So I stopped tvheadend42 as well (not just vdr):

# systemctl stop service.tvheadend42.service

and then w_scan works at least. So the issue is likely closer to tvheadend.

I set up logging for tvheadend:

and when trying to scan (IDLE ---me---> active ---auto---> IDLE) the log file contains:

# cat tvheadend.log

Looking for the message, I found this:
https://tvheadend.org/issues/3212

Then I opened the editor for networks:

I selected 19.2 E Astra from "Pre-defined muxes" and also in the "Orbital positions". When I reopen this the data above is shown.

And suddenly the Muxes and Services tabs started filling. Now I have to see if thinks work now but that seemed to be the issue. I am reasonably sure I tried editing this network a few times and deleted/created it. But maybe that was while I had the wrong drivers? Hard to tell by now.

I can watch the channels now via TVHeadend web interface. So this issue is solved.
