neumoDVB

[ptergrand]

The program is beautiful

 

[deeptho]

I followed the instructions on the installation page, so the last two commands I run are:
cd ~/neumodvb/build sudo make install

neumodvb/build/install_manifest.txt has the following entries:
/usr/lib64/libstackstring.so /usr/lib64/libneumodb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyneumodb.cpython-312-x86_64-linux-gnu.so /usr/bin/neumoupgrade /usr/local/lib64/python3.12/site-packages/neumodvb/pydevdb.cpython-312-x86_64-linux-gnu.so /usr/lib64/libdevdb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pychdb.cpython-312-x86_64-linux-gnu.so /usr/lib64/libchdb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pystatdb.cpython-312-x86_64-linux-gnu.so /usr/lib64/libstatdb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyepgdb.cpython-312-x86_64-linux-gnu.so /usr/lib64/libepgdb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyrecdb.cpython-312-x86_64-linux-gnu.so /usr/lib64/librecdb.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyschemadb.cpython-312-x86_64-linux-gnu.so /usr/lib64/libschema.so /usr/lib64/libneumoreceiver.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyreceiver.cpython-312-x86_64-linux-gnu.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyspectrum.cpython-312-x86_64-linux-gnu.so /usr/lib64/libstreamparser.a /usr/lib64/libneumoutil.so /usr/local/lib64/python3.12/site-packages/neumodvb/pyneumompv.cpython-312-x86_64-linux-gnu.so /usr/lib64/libneumolmdb.a

In neumodvb/build/CMakeCache.txt I can see
_Python_INTERPRETER_PROPERTIES:INTERNAL=Python;3;12;0;64;;cpython-312-x86_64-linux-gnu;abi3;/usr/lib64/python3.12;/usr/local/lib64/python3.12;/usr/local/lib/python3.12/site-packa ges;/usr/local/lib64/python3.12/site-packages

I am not sure why this happens. Perhaps something ubuntu specific?

I will check later.

I use QXL drivers with SPICE (see link).
I forgot to list it, but yes, I pipe dvbstream output to nc (netcat).

That is fine, but other programs work as well (e.g., dvbsnoop with the right options)

For some time I indeed used neumodvb for tuning and getting signal levels and in parallel I ran dvbstream and nc.
I know pretty much nothing about python coding (and to be honest not a lot more about bash scripts either).

Neither did I, until I learnt it.The basics are easy. Some more advanced tricks can be confusing or even surprising.

About getting signal levels, I run dvb-fe-tool, it used to work perfectly but a few months ago, a libc update seems to have brought a bug to light that randomly makes dvb-fe-tool crash at launch (it works ok on the subsequent launches).

Is there something from the neumodvb package (or blindscan tools) that could replace it in a command line?

I think neumo-tune might do it, but this program is not well tested. If I remember correctly it outputs sugnal levels (or it
would be easy to make it do that). The /dev/dvb/adapter/... can then be used to read the stream and do somethign with it.

deeptho ; Sir, can you explain exactly what this page means?​

if(!c.is_valid())
return;
auto start_time = system_clock::from_time_t(epg_record.k.start_time);
auto tp = zoned_time(current_zone(), floor<std::chrono::seconds>(start_time));

auto const info = tp.get_time_zone()->get_info(start_time);
start_time += info.offset;

 

[deeptho]

It reads time and converts it to the local timezone

 

[ptergrand]

It gave an error on this page, I deleted it, uploaded it again and uploaded it to github.com.

 

[deeptho]

That makes no sense. The code is needed and will not be integrated.
You also cannot upload it.

You are probably using ubuntu and need to upgrade ubuntu.

 

[ptergrand]

I uninstalled the program, installed it and it gave the same error again.

I deleted the error areas and it continues to load without errors.

I can't even scan the frequency, I enter the frequencies manually.

I live in Turkey. Since this program gives an error in the time zone, which time zone should I use?

 

[Llew]

@deeptho, Clicking OK in the little scan box aborts the program. Nothing in debug that helps me, but ! can attach it if it's any use.

That's the errors I have with the upgraded Ubuntu. Fedora upgrade to F39 built with no errors, but I have the shutting down problem as above.

Blindscan scan is great

In the words of Einstein: “Insanity is doing the same thing over and over and expecting different results.”

 

[deeptho]

Even though I upgraded Ubuntu, it still gave the same errors.

Upgrading means "installing the latest version" (while keeping any configuration you made).
Are you running ubuntu 23.10? Only that one will work. The other versions are too old.

 

[deeptho]

That's the errors I have with the upgraded Ubuntu. Fedora upgrade to F39 built with no errors, but I have the shutting down problem as above.

It should work in 23.10 (I tested that). Or do you mean "That's the errors I have with the NON upgraded Ubuntu."

 

[ptergrand]

ubuntu 22.04

 

[Llew]

It should work in 23.10 (I tested that). Or do you mean "That's the errors I have with the NON upgraded Ubuntu."

I should have checked my upgrade - I'm on 23.04

Next up, 23.10. Thanks for pointing that out.
