DAB keeps crashing

[5ras]

Hi,

I am using the Aaronia Spectran V6 ECO with SDRangel, and even with latest version 7.22.0 SDRangel keeps crashing. Sometimes when I start decoding, sometimes when I set the sampling rate. In the rare case when it starts receiving and decoding it does a fine job, until I change the frequency, then it crashes again. "Crashes" means, the program freezes for a few seconds and then completely closes without any further notes. The PC is a i7, 14 cores, 64GB RAM, no bottlenecks at all.

The receiver is set to full bandwidth, and of course the DAB frequencies are within its span. Receiving other stuff, like FM-N, FM radio with RDS, AIS, DAS-B, this all works perfectly with no issues.

Thanks for any input.

Ralph.

It's probably this bug in the underlying DAB decoder: https://github.com/JvanKatwijk/dab-cmdline/issues/97

I've encountered similar crashes but only when doing a "speedy" channel switching. And as Jon said it must be dab-cmdline locking issue. A kind of workaround that I found (and it works every time) is to give some time when switching channels. When scrollig comboBox with mousewheel, a mere 1-2 seconds delay is enough to avoid segfault.
