Bug: QLC+ (4.7.4) crashes when activates the OSC port

[Fanfoue]

Hello everybody

Since the version 4.7.3 I can’t use the osc anymore. When i choose to activated the OSC port, QLC bugs and stops.
I tried it on two differents PC, one with windows Xp and the other with windows seven.
The same problem occurred.
On the older version of QLC+ it’s work well.
If you have any ideas.

Thanks

Wrong thread. Moved.

Hi, this is weird because the OSC code hasn't been touched since a long time now.
Maybe it's a Windows deployment issue.
Can you check if there is a difference in the bundled DLLs ?

I am also having this problem. Occurs on both Dell laptop/Windows XP and Intel Desktop/Windows 7. Easily reproduced. Just create a new project, open the External Input config window for OSC, don't change anything, just click 'OK' and QLC+ crashes. (Needs an uninstall/re-install to get QLC+ to run again).

Happy to help anyway I can to get this resolved.

Further information ....
Versions 4.7.4, 4.7.3, 4.7.2 all crash as described above (on my Intel desktop W7).
Versions 4.7.0, and 4.7.1 seem to behave correctly (doesn't crash but I haven't actually checked OSC connectivity yet).

Which files are the ones that contain the OSC code ? Is it feasible to manually copy these from a 4.7.1 installation, into a 4.7.4 installation as a workaround ?

I just tried on Linux and it doesn't crash.
Maybe it's a Windows related thing. I will try there later.

In the meantime, can you try a Qt5 based version from the development thread and tell me if the issue is still there ?

[NickR]

Just tried to test with QLC+_4.7.5-TEST-20140912 but couldn't test OSC input since there is no OSC (or MIDI) inputs configured.

Happy to try again if there is a Qt5 version with OSC support.

If you delete registry key OSCPlugin from qlcplus, QLC+ starts again.

Qt5 build works OK.

[Massimo Callegari]

Hi, there's a file missing in the Qt5 bundle. Please add the attached DLL and you will see OSC.
I will upload a fixed bundle soon.

As for MIDI, it shows up here.

[Jsmoovey]

OSC still crashes when I enter IP Address. Enabling OSC alone doesn't crash the program. It's only after applying an IP Adress. The program will not start again until I delete OSCplugin from within regedit.

I am assuming your supplied file should be placed in the root of the installed directory? I have overwritten the file that was there. No luck :-( Qlc+ 7.1 is the last version that worked with OSC enabled. (Running windows 8.1)

[Massimo Callegari]

I think I found something but I'm not sure if it's the same issue.
Are you using an OSC output without actually specifying an output address ?

If so, I think I've fixed it on GIT.

[NickR]

I added the pthredGC2 dll, and tested OSC configuration. All worked OK - no crashes.

In answer to your question above - No, I was not specifying OSC output. Just 'Input' (and sometimes 'Feedback') - although the crash occurs with just 'Input' selected.
