Apparently constantly crashes in the background...

[ayunami2000]

When webcamoid is not running, apparently AkVCamAssistant.exe is, and is crashing multiple times a day.

Clicking a random one gives this:

After some point, they all changed slightly, which I suspect is a change in windows but I'm not quite sure (after a search it seems the bucket id is Microsoft's way of tracking the errors from this specific program):

The problem is that I can't reproduce the issue, that log does not show nothing useful, try with AkVCamManager set-loglevel 7.

1) How do I set those parameters? The program runs automatically by some startup script or something and restarts itself after it crashes.
2) I found ONE listing on google showing that the issue exists elsewhere. Note that this is not my computer and isn't focused around this specific issue but.... (on web archive if link decides to die)
3) I will run that command manually & I'll stop the other process. Later I will check for error logs. Where would it log to?
4) Webcamoid itself has always been really buggy for me and often quits, forcing me to reset the config. I forgot how I did that but...it's a regular issue whenever I (rarely) use webcamoid. Probably should be a separate issue

Also: One similarity I found between my device and the other device is that we both use NVIDIA and both have multiple graphics cards (although I only have one NVIDIA and one Intel)

3. I will run that command manually & I'll stop the other process. Later I will check for error logs. Where would it log to?

The logs for the assistant are located at C:\Windows\Temp and the logs for the manager and the plugin are located at C:\Users\User\AppData\Local\Temp, the logs are numerated by date and time.

Also: One similarity I found between my device and the other device is that we both use NVIDIA and both have multiple graphics cards (although I only have one NVIDIA and one Intel)

The graphics card doesn't play any role here (and anyway I won't be able to test it if that were the case), there must be something else that's crashing the service.

It hasn't made any log files (despite being reported as crashed 3 hours ago), and I can't find AkVCamManager. Also, looking at my webcamoid folder I found that, strangely, there is a copy of the AkVirtualCamera.plugin folder (with the same files!). So one AkVirtualCamera.plugin folder is in C:\Program Files\, and another in D:\webcamoid\share\. Is it possible that changing the install location breaks some parts of the program?

I just tried to reinstall all of webcamoid using the maintenance tool exe, but it still crashes upon running right after install. Should this be moved to another issue elsewhere? I ask because these could be related

Edit: Ok im like 9999999% sure that webcamoid crashes because I have a webcam device that is not in use (OBS virtual camera). It's still an issue because that makes the entire application crash just because of that one device. This could potentially be causing issues with AkVCam as well
Edit 2: I was right, and OBS comes with a virtual camera now so i no longer need this problematic plugin that causes issues with multiple applications that use the camera.

I'll wait a bit to see if the errors still show up

While writing this answer I figured out that I forgot to ask you, you installed the virtual camera from Webcamoid 8.7.1, right? if that's the case you don't have AkVCamManager and all the debugging facilities of the new plugin. Uninstall the old plugin like this:

• Remove all virtual cameras from Webcamoid from the Outputs menu.
• Uninstall Webcamoid.
• Execute this script as administrator to uninstall the plugin.
• And finally install Webcamoid and AkVirtualCamera from the daily build.

AkVCamManager is located at C:\Program Files\AkVirtualCamera.plugin\x64\AkVCamManager.exe or C:\Program Files\AkVirtualCamera.plugin\x86\AkVCamManager.exe, you can open a CMD and then call AkVCamManager as:

set Path=C:\Program Files\AkVirtualCamera.plugin\x64;%Path%
AkVCamManager set-loglevel 7

Probably yes.

Open a bug for this, I'll try to find a way to avoid the crash with that plugin.

I don't have AkVcamManager; I have AkVcamAssistant. And yes, it's in that directory, and it's the only exe in that x64 folder. (Same for x32 folder) and only the placeholder image is in the share folder (which I replaced with a custom image with the same name (which works))

You have the old plugin, do as I said before and uninstall it.

[ayunami2000]

Ok I did that, it is no longer crashing but now there is no virtual camera...the "add output" option does not appear to add any outputs, yet Virtual Camera is listed in the plugins section...

[ayunami2000]

Closing because original issue has been fixed: Had to update to daily build of AkVirtualCamera
