.net application crashing

[Buka]

I've a .net application using the portsip sdk for SIP telephony functionality (https://www.portsip.com/portsip-voip-sdk/).

The application starts fine, the wpf windows appear. I can start a video call that rings at the counterpart. But if I answer the call the app crashes and I'm not able to find the reason because of some cryptic output.

Of course I tested the app in a windows environment and it works fine.

The are some messages telling me some device is busy:

Code: Select all

libv4l2: error setting pixformat: Das Gerät oder die Ressource ist belegt
err:qcap_v4l:qcap_driver_init video format NULL renderer isn't available

Do I have to allow access to the camera somehow?

There is an unhandled exception. Is there a way to find the type of exception or even the message of the exception?

I know it is a very special case, but perhaps I have some luck and find someone who can give me some hints on how to continue finding the error. Any help is very appreciated.

Don't worry about that - this just means your version of Wine is built with Video4Linux support...

Installed dotnet40 with winetricks
installed dotnet462 with the microsoft offline installer (NDP462-KB3151800-x86-x64-AllOS-ENU.exe)

No don't do that!

If you really need MS .Net framework 4.6.2 then install it with winetricks directly:

Code: Select all

winetricks dotnet462

If you can't - then you need to update your winetricks script - to the latest build.
See WineHQ Winetricks...

Can the application run in a WINEPREFIX set to Windows XP?
If so - you might want to test this as well...
Wine support for the newer MS Windows API's - introduced in Windows Vista - is still a bit hit-and-miss...

Thanks for your reply, Bob.

Ok, I have done that. Unfortunately my company denies access to the dropbox where winetricks wants to download the slim installer from. So I downloaded it in an alternative way and copied it to ~/.cache/winetricks/dotnet462/ and restarted

Code: Select all

winetricks dotnet462

Hope this leads to the same result? The installer installed all the different dotnet versions but in the end I had an error "Error during execution 'netfx_fullp_x86de.msi /qb!'. File not found.". But it seems to work.

I also tested that. Still the same behaviour.

Any further ideas?

@Buka

Well the crash appears to occur in the .Net 4.0 framework libraries.
Usually applications are based on a single .Net framework version.
So just a thought - do you actually need .Net 4.6.2 framework?
Installing a higher version of .Net framework, then you actually require, is a recipe for disaster...

Have you tried running the application (in a clean WINEPREFIX) with just:

Code: Select all

winetricks dotnet40

The software needs at least .net version 4.6.1. I tried that also without success.

I also tried to start a simple video capture software with wine. I wasn't able to get a picture.

Then I found several hints that a webcam might not work with wine:
https://bugs.winehq.org/show_bug.cgi?id=16147
https://bugs.winehq.org/show_bug.cgi?id=37561

These are bugs from older wine version. But I can't find if it is solved now.
If it is solved: can someone tell me how to make the webcam work?

Otherwise it's time to give up here I think.

Those bugs are still open, plus three more related to webcams:
