Hi, thanks for trying. It is an indication (usually) that the decoder cannot keep up with the data stream. There is nothing odd with the settings above and I did not expect this behaviour.
I just tested again with a DX on my mac mini (M1) and no issues. So nothing has changed. What hardware are you running this on? I assume you can successfully run the SDRplay with other software on this machine?
i had this when tried to run aiscatcher on raspberry 1 with 512mb of ram, looks like it cant address memory
Hello jvde, Unfortunatley the issue for the endless 'Buffer Overun' messages maybe that the machine I tried to install it on is a non-native Apple variant. Its an HP Elitedesk G3 800 with MacOS Monterey, using Clover to boot the EFI and Opencore to 'Fake' the drivers that the OS uses. This 'Fake' driver for USB works ok on other SDR apps like CubicSDR and SDRPlay Connect. How knows what the issue is, but it could be OpenCore related ? I switched machine to another HP G3 800 and succesfully installed it on Linux Mint 21, no 'Buffer Overrun' messages.
It is difficult to say, somewhere the machine cannot keep up with processing the datastream. Odd that other programs might work but there is a lot of unusuals here to tip things over... did you see a high cpu utilization on the Mac with the program? Anyway, almost impossible to fix this I think.
Thanks for continued experimentation
I close this one as there is no clear issue to fix. Let's reopen when we have a concrete lead.
Hello, New User to AIS-Catcher. After watching the Tech Minds video. Wanted to try this program out. Successfully compiled and installed the latest version of AIS-Catcher on a Mac, running Monterey OS. Using an SDRPlay RSPdx SDR unit, the API 3.07.03 correctly complied with the Github install commands. Checked to see if the SDR uit can be seen with the command AIS-catcher -l, all good the unit was present. Then ran the next command to start the AIS decoding, AIS-catcher -v 10 -u 127.0.0.1 10110 -u 127.0.0.1 10111. The result :- AIS-catcher (build Jan 18 2024) v0.56-21-g2edf4415 (C) Copyright 2021-2023 jvde-github and other contributors This is free software; see the source for copying conditions.There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Is there an option to stop the 'Buffer Overrun' from happening ?
The webserver works as far as displaying a webpage, but tried to view anything thinking the Buffer Overrun would be neglected does not work, AIS-catcher -v 10 -u 127.0.0.1 10110 -M DT -N 8100. With port 8100.
So this 'Buffer Overrun' stops anything from going forward.
Is there a work around using an SDRPlay unit ?
Thanks.
