tvheadend scanning muxes problem, TBS DVB-S2, Linux Mint 13

Added by Fubbel Fubbele over 12 years ago

Hello,

I am having some problems with tvheadend and scanning the muxes.
I had tvheadend running quite a while ago on a different installation, but the driver of the used DVB-S2 card was not stable, but scanning there actually worked already.

I think this is some user error... but not really sure. I hope someone can help me or point me to the right direction.

This is my setup, new installation:
Linux Mint 13 Maya
TBS 8922 DVB-S2 PCI, driver installation compiled from TBS source. The sat card gets recognized correctly during boot.
tvheadend 2.12 installed over apt-get from lonelycoder repo.

Thats actually it. Installed Linux Mint Updates. So the system is up to date.

Installation of tvheadend runs fine. I can also access the webinterface.

I did the following setup within tvheadend:
Configuration -> TV Adapters -> selected "TurboSight TBS 8922 DVBS/S2 frontend"
selected "Autodetect muxes & Idle scanning"
NIT-o Network ID: 0
DiSEqC version: 1.0/2.0

So this is actually quite basic what is selected already.

"Add DVB Network by Location"
I open "Geo... Orbit" -> select Astra 19.2E -> at bottom select "Default Port 0 Universal"
This gives me Muxes:1 Muxes awaiting initial scan: 1
During this situation I can wait several hours/days and nothing happens?!

I have 2 LNB's through a DiSEqC. The other one is Hotbird 13.0E. The center/main LNB is the Astra one....
So adding a second satconf to tvheadend naming it hotbird switchport 1 (the default entry got switchport 0). LNB type: Universal.
After this I go to "Add DVB Network by Location" and add Hotbird 13.0E and select at the bottom the Hotbird satconf entry.
This now brings me 95 Muxes and 94 Muxes needing initial scan?!

Is the Astra Mux entry now suddenly scanned after adding Hotbird and didn't find a service?

At least at this point scanning runs through and the Muxes needing initial scan runs down to 0. But I don't get any services....

Aug 16 23:22:21 dvb: "12,245,000 kHz Horizontal (hotbird)" on adapter "TurboSight TBS 8922 DVBS/S2 frontend", status changed to No signal

What am I actually doing wrong? Where is the problem?

So far I haven't tested the sat card inside the linux installation yet. But have tested it on a Windows installation and there the card works. So the card itself is ok.

Maybe I am having a driver problem?
Maybe there are some reasons with the kernel? Linux Mint runs 3.x kernel
uname -a
Linux htpc 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Anyone got any idea?
As for some time and don't really know how to best go on or where to look for the problem.

Thanks for your replies. :)

regards

Looks like a similar problem to what I had enough my s2 cats when I first started using tvheadend. It was sending system type undefined and seems my driver dogs not apply a default.

Before we can really help you need to test with latest version of tvheadend (3.0).

Deb is available from Download.

Hello,

thanks for the fast answer.

I actually thought 2.12 is the latest stable version. As this version has got an repo from the dev.

I installed the 3.0 version with the deb package. Thanks for the link.

Everything looks fine now.
Added Astra 19.2 again, it added 1 Muxes to scan.
But right after 2 seconds the Muxes started to increase.

There are still half of the Muxes for scan left but got now about 800 services already.

Little late here already, so I will just test a little more and will report back over the weekend how everything looks.

Regards

Hi,

the scanning went through fine.
Did not have much time so I did not test with the Hotbird yet. But I think this will be fine now too.

The services I looked for worked fine for me now. Switching channels is also fine. Also the time it takes to change the channel.
I used XBMC as frontend.
