neumoDVB

[Llew]

Llew, what do you mean by "the bug was mentioned in v1.5"?

Can you try the latest master? It may be fixed but I cannot test dvb-t

Bug was in version 1.5 changes.
Scanning,spectrum acquisition and tuning.
Bug: Scanning DVB-Cand DVB-T muxes fails.

Your latest push in Github neumoDVB fails to fix DVB-T mux scanning (at least for me).

PCTV DVB-T/T2 dongle in Raspberry.

Same in updateDVB scans OK so not a signal issue.

 

[Llew]

TBS6522 in PC (Fedora or Ubuntu) has same problem with the DVB-T scanning.

Same tuner in Crazyscan scanning OK.

 

[deeptho]

LLew,
That must have been another bug in 1.5.

Did you actually recompile? DOr DVB-C the fix works.

How about sending a new log file?

Did you actually recompile? DOr DVB-C the fix works.

I have done from Build with no change. Should I compile with a new neumodvb download?

Here's a latest log file if it's any help.

 

[Llew]

Some success, at least with the Raspberry.

PC with TBS6522 to do.

Doesn't lock on the PC with TBS6522. Only with the PCTV DVBT/T2 USB stick (Sony CXD2820R, as in the RPi).

Uncertain whether the neumo log will be of any help, as scanning on the PC (Fedora, also with Ubuntu) has shown to work OK with the PCTV stick.

Llew,
yopu should check if the card works under linux with some other program.

I'm certain as far as I remember it worked on neumoDVB before the latest updates. I'll check the thread for a relevant post when i have time (busy elsewhere at present).

I don't have another program, I used to run Kaffeine, but don't have it on disk now.

Maybe I'm wrong in thinking I used the card for DVBT on neumo

Hi,
I started with Linux PC as a newbie, so sorry for my post. NeumoDVB shows me some "problems" and I can´t "run" the program.

Hi dx qwer

Guessing here, g++ command not found: check that g++ is actually installed by running this in your terminal :-

g++ --version

- or checking in /usr/bin for g++ and its version.

You have installed build-essential? (assuming you're using Ubuntu).

sudo apt-get install build-essential

g

 

[dx qwer]

Thanks a lot for your reply and useful help @Liew. Checked now what you wrote above. In my terminal it shows now:

g++ (Ubuntu 13.2.0-4ubuntu3) 13.2.0

I can open "neumodvb.py" now for the first time here.

That's good news

Enjoy the program dx qwer

 

[dx qwer]

Good morning,

today I noticed that following appears in the terminal when I open the program:
Cannot load libcuda.so.1

I have obviously not yet managed to install the drivers for the TBS 6909X, as the frontends list is still empty.

Ignore. According to deeptho, cuda isn't necessary to run neumoDVB.

have obviously not yet managed to install the drivers for the TBS 6909X, as the frontends list is still empty.

media_build using deeptho's installation instructions normally finds the drivers for TBS cards :-

Hello Llew,

since I have Ubuntu 23.10, I seem to get errors with the following command for "software for kernel compilation (for fedora)"...

Is there a command "software for kernel compilation" for ubuntu in my terminal?

 

[RyLe]

Hi

It's been a while since I had an error compiling the blindscan driver after each Fedora kernel update but this moment has come.

Going from a 6.7.11 to a 6.8.4 there are at least two kind of errors:

/home/ryle/blindscan_kernel/media_build/v4l/cec-notifier.c: In function 'cec_notifier_parse_hdmi_phandle':
/home/ryle/blindscan_kernel/media_build/v4l/cec-notifier.c:228:38: error: invalid use of undefined type 'struct platform_device'
  228 |                 hdmi_dev = &hdmi_pdev->dev;
      |                                      ^~

which can be corrected by adding

#include <linux/platform_device.h>

to

~/blindscan_kernel/media/drivers/media/cec/core/cec-notifier.c

but then, there are a bunch of errors about the function strlcpy being undefined like this one:

/home/ryle/blindscan_kernel/media_build/v4l/tbs_pcie.c: In function 'tbs_vidioc_enum_fmt_vid_cap':
/home/ryle/blindscan_kernel/media_build/v4l/tbs_pcie.c:112:17: error: implicit declaration of function 'strlcpy'; did you mean 'strscpy'? [-Werror=implicit-function-declaration]
  112 |                 strlcpy(f->description, "YUV 4:2:2", sizeof(f->description));
      |                 ^~~~~~~
      |                 strscpy

there are too many instances of strlcpy for me to patch by hand.

I think the blindscan driver may need a rebase with a current kernel.

I think the blindscan driver may need a rebase with a current kernel.

Assuming that this is not due to making a mistake while compiling: Why don't you use an older kernel?

 

[RyLe]

I haven't found a durable mean to stop my Fedora install from upgrading kernel packages.
When I can't compile blindscan_kernel because of breaking changes made to the kernel sources by a version change, I use grubby to go back to a kernel version I had modules compiled for.
The distro can only keep a certain amount of old kernel versions before the last known good one will be erased.

It will never erase the kernel you are running, so yo should be safe. Usually the problems like the ones you are experiencing
are due to not updating linux_media or media_build or starting from some "dirty" build tree
