ZWO ASI183MC Segfault

[pijulius]

Hi Guys,

Just received the new ZWO ASI183MC cam and unfortunately even with the latest oaCapture 1.6 I have a segfault right away when I try to connect the camera.

I had another ZWO before and with that it perfectly worked (had a lot less resolution so not sure if that's the reason) and also can confirm it works with AstroDMX and FireCapture but I'm an oaCaptura fan for a lot of reasons so could you please help me figure out how to fix this?

I'm attaching the core dump maybe it helps, the fail happens at: oaZWASI2InitCamera ()

Thanks in advance and thanks for this app!

Regards, Julius coredump.zip

FYI: just compiled oaCapture from source and not sure what it does but commenting out the following does make it work:

File: liboacam/zwo/ZWASI2connect.c Line: 1270

//cameraInfo->frameSizes[2].sizes[0].x = 2748; //cameraInfo->frameSizes[2].sizes[0].y = 1836; //cameraInfo->frameSizes[2].numSizes = 1;

That should be an acceptable temporary fix.

I think I've fixed the problem in development. Just need to check. If so I'll compile a new version.

Thanks for confirming, I just checked the file here: https://github.com/openastroproject/openastro/blob/master/liboacam/zwo/ZWASI2connect.c

but still see the three lines there for: ZWOCAM_ASI183MM

In any case thanks for the new compilation in advance and forgot to tell you it's Fedora 30 that I'm on right now.

The actual fix should be this one here:

Unfortunately with the git version it now says "open of camera 0 failed" and wont connect to the camera. Please let me know if there are any tests I can do to help.

Sorry, Never mind! Had to restart for wathever reason but works just fine now with the git version! Thanks again for the quick fix and help!
