Did you install the drivers?
Does the following command show adapters:
ls -al /dev/dvb

ok , this time it show me some thing
But I install first TBS-Linux-Media

some of my early "Error" are alredy reported here but not for Fedora :

Adapter 0 will be the first tuner of your pci card (referring to the LNB 0 input of your TBS 6903X tuner).
Adapter 1 is the second tuner in your card.

Usually the colour of the Adapter 0 line if chosen is blue, as shown in my frontend page, although my Mint install of neumodvb does show it as yellow.

As well as the TBS 6903X, I have a TBS6903 in my PC, which in my configuration is Adapter 0 and 1).

 

[deeptho]

Adapter 0 and adapter 1 are connected to the first rf input.
Adapter 2 and 3 to the second input.
In order to use adapter 1 and adapter 3, you have to edit their lst column and change "master"
to 0 (for adapter 1) and 2 (for adapter 3)

To enable editing, press 'Alt-E'.

Afterwards you have to create lnv entries.

You also need to update the drivers to have more meaningful adapter names.

I only like Fedora34 because I don't lose Graphic resolution when I instal drivers

losing Graphic resolution happen when I install Drivers in both Ubuntu 18 and 20 !

I have one Error related to "Tunner _bw and tunner_freq" think and this happen after ***make -j8**
kernels package has not the same versions!

Please read the documentation about your diseqc question...

@deeptho
For my convenience, I'm attempting a compile of neumodvb on a Raspberry Pi with Fedora 34.

cmake completes OK, but make -j8 errors at lang_codes, with the suggestion that I "insert an explicit cast to silence this issue"

Could you give me a clue on what I might be able to do to clear this one?

TIA

 

[deeptho]

Llew,
Probably the compiler version is different.
I have added an experimental patch. Not sure if it will work.

Note that neumodvb might not work (without further changes) on 32 bit operating systems.
It could be that raspberrir pis is 32 bit. Then some changes may be needed (or not. It would be good to test).

Magic. It's fine, thanks.

On Raspberry Pi 4 4GB.

Kernel 5.10.74-1.rpi4.fc34.aarch64.

TBS 5927, so not certain how well it'll perform.

More to do, as I don't know if this kernel will work, i.e blindscan etc.

 

[deeptho]

You can also try neumodvb with standard drivers. There is no blindscan then, but mux info can still be entered manually
and then after scanning one mux, many will appear.... If it works....

 

[Llew]

OK, a job for tomorrow.

 

[deeptho]

I have now finalized the C-band support in neumoDVB and took the opportunity to fix a few bugs. This was needed to
get t2mi working on that satellite. The screenshot below shows one of the russian channels. This requires two scans:
the first scan (spectrum scan) locates the DVBS mux. The second scan (on the dvbs mux list panel) then automatically finds the
t2mi streams. Some of te streams works. Many show the same channel.

The transponderlist below shows what I could lock (1.2 meter dish). The service list is incomplete.

Some more minor fixes will be needed, e.g., to indicate proper polarisation (Vertical is incorrect; should be "left")

The latest version has various little fixes regarding screen layout, and all kinds of bug fixes.

 

[deeptho]

I have just uploaded a new version of neumoDVB: neumodvb-0.6.2
Compared to neumodvb-0.6.1, this includes:

• Many bug fixes
• Improved theming
• Added volume up/down command
• better support tbs5927
• Added frequency and SNR readout for current cursor value in spectrum scan
• Improved blind tuning for low symbol rates
• Ensure that program also works (without blindscan and spectrum) on original linux drivers
• installation instructions for debian (thanks to Llew)
• Better list of pre-requisite software
• C-band now properly works.
• Support for Circular LNBs (display LR instead of HV) and LNBs with swapped polarisations
• Database format has been upgraded. Normally this will trigger autoconversion of existing databases.
• T2MI scanning also works on 40.E
• Service, muxlists... now allow simple value based filtering.

Just remember to update the linux drivers as well. Some bugs have been fixed there as well.

deeptho, I can't complete a compile due to a possible error in the statdb_extra.cc file. This may predate your latest changes; I havent tried compiling neumodvb recently.

 

[deeptho]

Llew,

this should be fixed now in master.

 

[Llew]

OK, thanks deeptho. I was at the time building neumodvb for a Raspberry Pi, for which I have at last obtained a kernel that allows my TBS 5927 to be registered.

Hi! Thanks for the huge effort of building this piece of software. Have been looking for a blindscan solution on linux for my 6903x for quite some time so am very keen on getting this up and running.

I am running Fedora 35 with kernel 5.15.6-200.fc35.x86_64
I have successfully built and installed neumodvb, blindscan and the blindscan-kernel

I have these issues at the moment

1. In NeumoDVB under Lists > Frontends I can see my card but the "blindscan" tickboxes are unchecked.

I build media and media_build with the instructions from GitHub - deeptho/linux_media: TBS linux open source drivers but I was failing after "make allyesconfig" so I ran the script as instructed at Issues · tbsdtv/media_build with

Just call the build utility:
    $ ./build

Then, install the drivers as root, with:
    # make install

2. The graphics in the Spectrum window seem broken and I get this in the console

Traceback (most recent call last):
  File "/usr/lib64/python3.10/site-packages/wx/lib/agw/peakmeter.py", line 681, in OnPaint
    self.DrawHorzBand(dc, rc)
  File "/usr/lib64/python3.10/site-packages/wx/lib/agw/peakmeter.py", line 787, in DrawHorzBand
    points[0].x = rectPrev.GetBottomLeft().x + self._meterData[vert]._falloff*maxWidth/self._maxValue
TypeError: 'float' object cannot be interpreted as an integer

3. When running this

./neumo-blindscan -c spectrum -U3 -pH -a0 --spectrum-method sweep --spectral-resolution 500

I get this error

FE_GET_EXTENDED_INFO failed: Unknown error 524
FE_SET_PROPERTY clear failed: Bad file descriptor
EPOLL Failed: err=Invalid argument
neumo-blindscan: /home/ms1-cpu/Programs/blindscan/src/neumo-blindscan.cc:1834: int main_spectrum(int): Assertion `s==0' failed.
Aborted (core dumped)

 

[deeptho]

Helmet,

this code has never been tested on fedora35.

The first problem is probably due to some changes in wxwidgets.
You could try replacing the line
points[0].x = rectPrev.GetBottomLeft().x + self._meterData[vert]._falloff*maxWidth/self._maxValue

points[0].x = int(rectPrev.GetBottomLeft().x + self._meterData[vert]._falloff*maxWidth/self._maxValue)

But I don't know if this will work or be sufficient. Also there exist two incompatible and different versions of wwidgets
in fedora34. Only one works. I do not know about fedora35.

The second problem points more to the blindscan drivers not being installed (jut a guess).
From the description above, it seems you did not follow the specific instructions for druver building and installing, which could
explain it

What do the following commands show
ls -al /dev/dvb/adapter*
cat /sys/module/dvb_core/info/version

 

[helmet]

deeptho,

I decided to install it on a fresh installation of Fedora 34 as to eliminate uncertainties.

I installed neumodvb and blindscan following their respective instructions on github and was successful. Am still having trouble with blindscan-kernel though.

I reached

make -j8

Got this error:

/home/ms1-cpu/blindscan_kernel/media_build/v4l/bttv-gpio.c:64:19: error: initialization of 'void (*)(struct device *)' from incompatible pointer type 'int (*)(struct device *)' [-Werror=incompatible-pointer-types]
   64 |         .remove = bttv_sub_remove,
      |                   ^~~~~~~~~~~~~~~
/home/ms1-cpu/blindscan_kernel/media_build/v4l/bttv-gpio.c:64:19: note: (near initialization for 'bttv_sub_bus_type.remove')

I installed all the dependencies listed in the instructions, also installed RPM for Fedora 34 and the Python dependencies at which point I was having some trouble with "make dir DIR=../media" so I ran all of these commands as recommended in this forum thread which solved it.

sudo dnf update
sudo dnf in kernel-headers kernel-devel
sudo reboot
sudo dnf install perl-Proc-ProcessTable
sudo dnf install patchutils
sudo dnf install boost-static
sudo dnf install cmake
sudo dnf downgrade cmake
sudo dnf install 'dnf-command(versionlock)'
sudo dnf versionlock cmake
sudo dnf install perl-Digest-SHA.x86_64

But as I said I am now stuck at "make -j8". I have tried with both the "master" and the "extra" branches from the tbsdtv/media_build repository and for each of them I deleted and rebuilt but still with the same result.

Sorry for causing inconvenience but it seems there's just a little more to go, thanks for helping out.
