2.1 scanning crash #69

Hi,

I unzipped 2.1 in the AbracaDABra folder and it worked perfectly well. Then I deleted the ini file to have AbracaDABra rebuild it and start by scanning for muxes. This didn't work and the scanning crashed AbracaDABra after having scanned a few muxes.
Solution: restore my back-upped original ini or start a scan and stop after a few muxes. Then continue building the ini by manually tuning to all muxes one by one.

You do not have to delete INI to do the rescan - just go to menu - Clear service list. Nevertheless it should not crash, I will try to reproduce this problem on Windows, thanks for reporting.

2.1 also crashing when doing a band scan, so not deleting the ini file! Solution: delete the libdabsdr.dll and replace it with the previous one!

Yes, confirmed. Just had a crash in manual scan. But tried to reproduce it with gdb and a video but did not see it again.

In my case I have a very weak signal in 8A of the same mux which I have locally on 6A. So, it's the same content.

After more than 10 trials, this is a video (crash in minute 1:05) and gdb output:

Update: the crash is at 7D and even 1.99.4+ (04ac900) had that problem, so this is not related to 2.1 only.

This channel is used by two different muxes (Slovenia and Italy), but both are too weak, although I get a "Signal found" in previous version

Thanks for all the reports. I think I have found the root cause that explains crashes for 2.1. However, I have no idea about the crashes for version < 2.1, I would need more information, ideally raw file that can be used to reproduce the crash.
@andimik Can you reproduce the crash with DABSDR < 2.1 on 7D? Can you make a raw file in other tool and try to reproduce the crash when going from raw file?

I fear we were talking about two different versions.

I meant AbracaDABra version and you DABSDR version ...

Because my 1.99.4+ (exec file in different folder under Ubuntu) already uses DABSDR version 2.1.0.

What would you like me to test? An older version of DABSDR?

KejPi commented Mar 15, 2023

OK, it makes sense now :-) Then we are aligned, the bug is in DABSDR 2.1. I will release DABSDR binaries soon today and then I would like to ask you to test it with your setup to be sure that I have not overseen anything before release new version of AbracaDABra.

I've just cloned an older version which uses DABSDR 2.0.0

Could not see a crash here, so you are right.

It means a problem. It happens when DABSDR is not able to process the data fast enough. Does it start to happen after update to 2.1.1? If this is the case then there is still some problem :-(

I've tested all three options in the gain control.

The message appears in all 3 cases and mainly in that channel which was crashing before (in my case 7D), but also on some empty channels (= not on all).

Does it start to happen after update to 2.1.1?

I also get it under DABSDR 2.0.0

Well, synchronization is quite CPU demanding processing, now it needs even more MIPS due to selectivity filter. I am running the app on Ubuntu on >10 years old laptop now and do not see any samples dropping. I am trying all channels and it does not happen.
Do you see high CPU usage when this happens? Maybe some process hanging in the memory? I hate to say that but have you tried to restart the PC?

On a very very weak signal top says, Abra uses more than 100%, on a normal signal (which can be decoded in the end) the value is 10-15 % typically.

Yes, CPU usage is the problem. I assume that you are running Release build. But I do not see such huge difference between channel with signal and without. Does it happen with prebuilt AppImage too?
Do you also have high CPU usage when running from file (the same channel recoded from other tool)?

Qt-DAB: 60% in top on a very weak channel

Then I've made a recording of the same channel and played it (continuously) in Abra. It's far below 100%.

CPU issue does not seem to be related to this issue thus I have created new issue #71 to continue the debugging there.
