neumoDVB

satesco · Sep 30, 2024

You must consider some prerequisites when installing @deeptho's driver, which is true for everything when building something in Linux.
In this case, it's about Git, a compiler that allows you to access the source code.
Then there's libproc-processtable-perl .
Check if you installed Git in a terminal with the command: git --version
If you get a negative message, then you need to install it like this:

-sudo apt update
-sudo apt upgrade -y
-sudo apt install git
-git --version

Then install; libproc-processtable-perl
At each command line, you should see on the terminal that something happens next:
mkdir ~/blindscan_kernel
cd ~/blindscan_kernel: git clone --depth=1 GitHub - deeptho/linux_media: neumoDVB blindscan drivers media_tree ./media
etc,etc,etc.
But better, as @deeptho says, to read each paragraph from his site: linux_media/README.md at deepthought · deeptho/linux_media

I don't know how much anyone can help you if you haven't put any "bricks" when you want to build something.
I understand. I was in your situation myself, and I went through many tribulations when I first tried to install the neumoDVB driver and application.

Switching from Windows to Linux or any operating system is like learning a foreign language mentally; you have to think like a native speaker of that language, not words and sentences.

@deeptho provides us with "the bricks" and instructions for arranging them.

OK, it seems I had not installed the git compiler previously.
This has now been installed and shows up as version 2.43

I then created and navigated into the directory /blindscan_kernel OK However after that I got an error of too many arguments when entering the line of

git clone --depth=1 GitHub - deeptho/linux_media: neumoDVB blindscan drivers media_tree ./media

I think I am going to run into repeated errors and issues in trying to get nuemoDVB installed and operational due to my zero knowledge of what I am doing.
If anyone who can resolve this and get the installation completed and operational I can provide access to the PC via Team Viewer and would make a donation to the forum and to the person for assistance.

Other than that, I will use the TBS6904SE card elsewhere and have to leave this mini project until another day.

@moonbase,
I would really advise learning some basic elements of linux. What you type above will never work as your start with a "

Thank you for your reply.

My need to get this working is at the level of "nice to have", it is not a critical need.
I might come back to this another day but for now I will leave it as I can see numerous issues ahead.

Still hoping to have Manjaro or one of the other Archlinux distros working with neumodvb eventually. We have Fedora and Ubuntu; another choice might add to the fun.

I'm using Manjaro release 24.1 and kernel 6.10.11.

At present, neumodvb in Manjaro is giving me a problem with spectrum scanning. The last time I was doing something with Manjaro was back in July '23, with a successful spectrum scan of a satellite (post #854).

Scanning a spectrum now unfortunately gives no peak markers or tp info, except at the end of either a low or high band scan (or in the case of a full band scan, just at the high end.

@deeptho, any ideas on what's going on there?

In neumo.log, line 223 spectrum acquisition shows 10700000 - 117000000, but later no mention as far as I can see of marking the peaks or whatever the description is of that action?

Pacman.log added if that helps. (similar to debug.log in Fedora I think). Nothing in the console.

Problems could be with Archlinux's wxWidgets version perhaps, but I have checked wx directories and files (site packages etc) against Fedora's and they seem identical. Maybe it's the actual version that's the culprit -

Manjaro -

Python 3.12.6 on linux, wxPython 4.2.1 gtk3 (phoenix) wxWidgets 3.2.4
import wx
wx.version()
'4.2.1 gtk3 (phoenix) wxWidgets 3.2.4'

Fedora -

Python 3.12.5 on linux, wxPython 4.2.1 gtk3 (phoenix) wxWidgets 3.2.2.1
import wx
wx.version()
'4.2.1 gtk3 (phoenix) wxWidgets 3.2.2.1'

Some help would be appreciated on the spectrum scans if anything like that has been reported at any time - of course, they're still working OK in Fedora and Ubuntu.

This is really strange. Did something appear on the console?
And what happens when you press the blindscan all button?
And do you think that the 12713 mux was really at that frequency?

In this case the log files were of no help...

Nothing except the ever-present 'Cannot Load libcuda.so.1'

deeptho said:

Nothing. Further, clicking on a mux peak of any known working frequency in the graph has no result.

deeptho said:

Indeed it was. An encrypted feed from Brands Hatch.

Llew · Sunday at 12:25 PM

I just did a full spectrum scan again, and noticed that before it starts the upper range (17000 -12750), I have the end V and H muxes showing as in the first picture (11670 /11684), but these disappear as soon as the upper range has completed its scan, leaving just the end frequencies showing as in the second picture.

It could be some incorrect lnb setting, perhaps some partial recompile (did you recompile), or some problem with some python library.

Try adding the following 2 lines in make_tps, in file neumoplot.,py

Python:

            print(peak_freq)
            print(peak_sr)

This should be added here:

Python:

        if recompute:
            from pyspectrum import  find_spectral_peaks
            peak_freq, peak_sr = find_spectral_peaks(self.spec[:,0], self.spec[:,1])
            self.peak_data = np.vstack([peak_freq, peak_sr]).T
        else:
            with warnings.catch_warnings():
                warnings.simplefilter("ignore")
                self.peak_data = np.loadtxt(tpsname, ndmin=2)
        print(peak_freq)
        print(peak_sr)

Note that python is very fussy about spaces, tabs.
This should then print the peaks found on the console. We need to figure out if they are different than the ones on screen.

Anyone else having issues with blindscan at 9.0E satellite. It starts ok but after couple of scanned frequencies just hangs there like it is scanning but nothing hapens and stays like that until I abort it. Could it be that italian streams are causing this? I have couple of satellites already and works fine and today I activated 9.0E and couldn't complete blindscan.

The console with two muxes at 12692. A lot of repetition.These will be both V and H as seen in the picture. Appears to be two feeds competing with each other in both polarities.

There's also one at 11684.75, which will be the 18686V Sky Daystar channel, which has SR of 23000, not 19451 as printed.

I have to tune that frequency manually, as I have said, nothing happens if I try to do anything from the graph, unless it's a found mux at the end.

I would check it, but busy with another satellite at the mo. Maybe later.

Can you double check that you actually compiled the code and not mixed some old and new one?
This could also happen if you have ever installed the code, instead of just recompile it.

If that does not help, then add again a print line in make_tps, this time on top.
The output may be very long, but I need it all.

Python:

        recompute = True
        print(self.spec)
        if recompute:
            from pyspectrum import  find_spectral_peaks
            peak_freq, peak_sr = find_spectral_peaks(self.spec[:,0], self.spec[:,1])
            self.peak_data = np.vstack([peak_freq, peak_sr]).T
        else:
            with warnings.catch_warnings():
                warnings.simplefilter("ignore")
                self.peak_data = np.loadtxt(tpsname, ndmin=2)

Do you mean rebuild/make neumodvb with the new lines in make_tps?
I simply copied what appeared in the console. Can you explain how I should have compiled the code? (sorry, not very familiar with the procedure).

Anyway, I've added the print line on top as suggested. Here's the console O/P and corresponding spectrum scan.

Do you mean rebuild/make neumodvb with the new lines in make_tps?
I simply copied what appeared in the console. Can you explain how I should have compiled the code? (sorry, not very familiar with the procedure).

Anyway, I've added the print line on top as suggested. Here's the console O/P and corresponding spectrum scan.

Code:

Recompile means:
cd ..../build
make

Did you remove the lines I asked you to first add?

To me it seems that the problem is in the code that computes the peaks.
which is the code that should be compiled, or perhaps could fail due to something specific
in archlinux (the latter is unlikely)

Yes,that's what I did.

No, I left them in. Should I have removed them?

Not sure how to progress now.

Maybe someone might like to try an Archlinux distro (Manjaro perhaps) to compare results. The dependencies are mostly the same as used by Fedora and Ubuntu, apart from two or three that are Archlinux specific. Another post perhaps with some instructions might be useful.

Did you install manjaro from scratch?
Perhaps you have something left over from an old instalation of neumodvb.
E.g., something called pyspectrum*.so in /lib or /li64 or /usr/local/lib64 or /usr/local/lib ...

Currently I have installed Manjaro 24.1 on a disk shared with Fedora. No other Manjaro OS on that disk. Updated and upgraded, then installed your media and neumo_media_build for my card adapters. Installed neumodvb with all necessary requisites.

When spectrums scanned successfully the last time I tried neumodvb in Manjaro (July '23 - I can't find a later date on which I used it), I was on Manjaro 22.1 release, so maybe there's some program/package updated in the 23.1 or 24.1 release that is causing the problem. Maybe that's unlikely, but I don't know.
New neumodvb versions have been introduced since that date, 1.2.1 - 1.7 , but in any case I haven't had any problems with spectrum scanning in Fedora or Ubuntu over the period.

I'll install Manjaro again on another disk in due course.

LLew, what does "a disk shared with..." mean? Probably Fedora and Manjaro are on different partiticns
and cannot interfere with each other.

As you have used manjaro on the past, it could be that some library remains from an older install (which is why I advise to NOT install, but run directly from where the code is compiled). So try to find them....
(see earlier message)

With some debugging the cause can be easily found, but then I would need remote access (ssh or something).

Different partitions on the same disk in the case of one Manjaro install, but the Manjaro I'm using now is the only OS on the disk, nothing else.

Doesn't apply at present, I won't be using that one while I try to sort the current problem.

I'm just now installing another Manjaro on a new disk, we'll see what it's like when I've built neumodvb.

Thanks for your help deeptho.
