Tvheadend

Here ist the SCR Kernel Patch for Kernel 3.7.10 -> http://m74.libra.uberspace.de/oc/public.php?service=files&t=043415c123c4bfebee678f97b3be8dc8
You have to build a new Kernel with this Patch, Howto: http://www.howtoforge.com/kernel_compilation_ubuntu -> patching Kernel https://www.kernel.org/doc/Documentation/applying-patches.txt
After that, you have to configure the Kernel SCR Parameters with the dcv-scr-setup tool (included in the Patch)

Hope it helps.

thanx!

Instead of a strange kernel patch which you'll need to apply again and again, you could also try the code I posted to the feature tracker https://tvheadend.org/issues/1752

Native SCR in TVHeadend!!!

Great!!!

Uhh

Yea

That sounds great!

I'll give it a try this week and let you know if it worked for me.

Jun 9 19:35:36 cucumber tvheadend¹⁴⁰⁴³: en50494: uni_scr out of range
Jun 9 19:35:36 cucumber tvheadend¹⁴⁰⁴³: dvb: en50494 setup failed -1

Any idea what wrong there?
I entered my SCR Freq. in the Config, tried it with Channel 0 and 1...still this error.
And no, i dont need a PIN

OK, what do I have to enter where?

I have an "Inverto Unicable Black LNB".

Free SCR Channels are 2 and 3.
Frequency for 2 is 1680 and 3 is 2040

Your screenshots look good at first glance. Does it work?

I have the following in the config files:

}

Can you also show your "Multiplexes" tab?

Matthias strack: the out of range message is triggered by uni_scr (SCR channel #) is < 0 or > 7, so it would be interesting to see your config file for the adapter. The parameter is named "uni_scr" in there (see above :))

Unfortunately I'm on the road this week and cannot really test. I have an USB tuner box with me, but no signal, so only theoretical tests are possible

I don't use the default entry but the entries 2 and 3. The difference between astra and hotbird is only the port which is interpreted as the "bank switch" bit, switching to input A or B.

{
        "id": "1",
        "port": 0,
        "name": "Default (Port 0, Universal LNB)",
        "comment": "Default satconf entry",
        "lnb": "Universal",
        "uni_scr": 1,
        "uni_qrg": 1210,
        "uni_pin": -1
}

This is my config, still the same error.

If you add the initial mux (for Astra) for example, you should have a ~/.hts/tvheadend/dvbmuxes/<your_adapter_name>/<your_adapter_name>_satconf_?

in my case (with a different adapter, but still no signal to test...):

}

I think that the "satconf: 2" is important here, as it matches my satconf (I added one for unicable).

But then I'm very new to tvheadend and don't really know how this all plays together. I'll do more test on the weekend once I have a signal to test.

Well...it works...my fault.
I didnt specify the satellite configuration while adding the muxes.

Hi,

thank you for your reply.

Hi, I had quite a lot of work yesterday, but this afternoon I can have a nother look at the config.

My problem is, that the button "Map the DVB-Services to channels" doesn't activate. So I can't search for any channels....

First Step is 'Add DVB Network by Location..', then TVH scans for Multiplexes (afaik).
If its done the Button 'Map DVB Services to channels...' should be active.
You can check what TVH is doing via the Status Page.

'Add DVB Network by Location..',

OK I'm a step further.

One problem occured.

I've got an Reciever that uses SCR0 (freq 1210) and SCR1 (freq 1420).
tvheadend should use SCR2 (freq XBMC 1680) and SCR3 (freq 2040).
For some reason I only can use SCR2.

I deleted the config and tried all over. But the problem is still there.

I added a few screenshots again. Or do you prefer console output?

If it helps, i can give you a ssh access. ...

"switchport" can only be 0 or 1, and unless you have a two position unicable matrix, you need to set it to 0.

This needs to be fixed in the Webfrontend, that entries with switchport > 1 are not possible if a unicable port is selected. Unfortunately, my web-foo is almost zero :-)

for now, just set switchport to "0" and it might work much better :-)

If you are using two DVB cards, you should set one of them to use SCR2 and the other to use SCR3 to make sure both are not using the same channel accidentally? But then I'm not really sure about the inner workings of tvheadend, this is all pretty new to me.

ssh access is not (yet) necessary, I think we'll sort it out :-)

I set the switchport to "0" on both DVB cards.
(I have a digital devices card which has two tuners on board)

DVB-1 has SCR2 -> finds channels
DVB-0 has SCR3 -> doesn't do anything, multiplex starts with quality = 100% but then ends up with: "frontend status says: Frontend status "no signal""

Ok, that's interesting. I'm looking at the code trying to explain it but I can't see how this happens.

Could you try to switch the SCR assignment between DVB-0 and DVB-1 and test if this might be frontend related?

How did you connect the tuners to your cable?

Cable -> splitter -> tuner1/tuner2

or

cable -> tuner1 -> loopthrough to tuner2

(in case your board has loopthrough ports.
I'd guess the second would not work well.

Could you ever test both tuners on a non-unicable setup to ensure both do send DiSEqC commands correctly?

Ok, my tuners are connected:

Cable -> splitter -> Tuner 1 / Tuner 2

I swaped SCR2 and SCR3. Only SCR2 works.

I had the card working in a Windows Mediacenter (Win7) with both tuners.

Ok, I'll test it when I'm home again and try to reproduce it.
I have both a Inverto unicable LNB on one dish and a Inverto IDLP-USS2OO-CUO1O-8PP with two LNBs on another dish to test, so let's hope my setup has the same problem :-)

I think I found the problem.

Make sure you set the PIN to -1 if you don't need it, otherwise the LNB will not accept the commands.
I'd bet that you have PIN -1 on SCR2 and PIN 0 on SCR3.

The problem is, that the web frontend defaults to PIN=0 when adding a new config, which is more often wrong than right.
I'll see what I can do about that, but as I already wrote: the web-stuff is not my strong part

Edit: I now pushed an update that defaults to PIN==-1 also for new satellite configs via "Add entry"

I reworked the code, the setup should now be more logical.

Best is to check out again, since master branch has changed (old master is available as branch "en50494-1st-try").

Now, the SCR#, Frequency and Pin are configured in the adapter configuration, only the port is configured in the satconf settings (port is not often used anyway).

So in your case, configure one adapter to SCR2 and the second to SCR3. I'm pretty sure it will work.

Defaults are also better (PIN is -1 per default).

If this one works well for you, I'll do a pull request to get it upstream.

cool

I'll start with the new code and post the result!

Thanx for your work!!!!!!!

Ok, looks much better now.

Channelscanning works now on both adapters.
Now I can start making the other configuration steps.

Any clue when/if youre code will be added to the main branch?

OK, everything works,
except for the channelimages (imagecache: failed to download /mnt/samba/TV-Aufzeichnungen/xbmc/Channellogos/"zdf hd.png"),
but that is an other topic.
