1 month ago I'm guessing this is a settings issue. Try looking for the Qt settings file on your machine and changing the value for UDP::Protocol to "JSON".
It would still be nice to have it catch this, I will look into a fix.

1 month ago I did not have any luck finding a Qt settings file. But, I looked at lines 99-102 in udp_server.cpp. After clicking Start -- but before the crash -- we look for UDP_Server::protocol in QSettings. (I can't figure out where the QSettings file is :( )
Is that what you're referring to?
It looks like QString protocol defaults to "JSON" in any case. That's the value I see in protocol after line 100 executes.
Thanks for looking at this!

1 month ago Same crash here, just my luck that I wanted to try out for the first time the UDP stream functionality today. My crash report looks to have some extra info, this is version 3.9.2 installed from the AUR for reference.

Aborted (core dumped)@zdavkeos : I found the settings file, and added an entry to set UDP protocol to "JSON." No change.
I've attached a patch here that appears to fix the immediate issue. I can turn this into a PR if it looks appropriate.
Problem description
Let me say, I'm sure this is a local problem of some sort; others seem to use UDP Server without trouble. But for me:
Launch PlotJuggler; select UDP Server in Streaming drop-down; click Start. PlotJuggler terminates with:
(full backtrace below)
Answer these questions (or I will ignore your issue)
Describe your platform / Operative System and the version of PlotJuggler you are using:
Compile and try the latest version in the main branch and check if the problem persists.
See above; built with:
Behavior is the same with or without
-t. But maybe I need to do something with the sample data before Starting?No data source here; just
Starting the UDP Server.Here is the backtrace output from PlotJuggler:
