Original GitHub issue: https://github.com/NickeManarin/ScreenToGif/issues/702

I installed ScreenToGif to my Win10 system, it works well. But other applications like "Camera App" or "Zoom" cannot use my camera anymore, the camera will keep rebooting when these applications try to use it. It might be the ScreenToGid didn't release the occupation of the camera when it quit. Please help.

Only one app can use the camera at given time. I just tested in here and the Camera app was able to find and use the webcam after closing the Webcam recorder (not even closing the app itself).

Try restarting the computer.

Thanks for replying me, yes of course only one app can use the camera at given time. But I've tried:

  1. Restart my computer -> doesn't work
  2. Uninstall ScreenToGif and then restart my computer -> doesn't work
  3. Reinstall ScreenToGif to find any configuration -> the reinstalled ScreenToGif can still work well but other Apps don't work at all
  4. Ask Microsoft for a help, they told me it's related to the camera occupation of third party application. The solution is try to reinstall recover or reinstall Windows (what a funny solution)

I guess maybe ScreenToGif modified some key value in windows to keep the occupation by itself?

Thanks for your help!

Try this:

https://www.windowscentral.com/how-see-which-apps-are-using-your-webcam#:~:text=%20How%20to%20see%20which%20app%20is%20using,Click%20Kill%20Process.%208%20Click%20OK.%20More%20

I was able to find this when testing:

If you find any app using the webcam, kill the process.

Also, before that, check if ScreenToGif is not running, but minimized to the system tray.


Wait, you wrote that you already restarted the computer. So, this won't work.

Thanks for helping, I tried, but no, doesn't work. The process is clean, and actually, the camera app can access the camera for 0.1s repeatly.

When I open the Camera App the image shows up and the camera light is on for 0.1s. Then the camera will reboot, and keep rebooting forever.

Thank you so much for your help

And I tried to disable the camera device then enable it. Doesn't work

Let's see if there's any other non-destructive way to fix this.

  1. Have you tried to uninstall the camera driver and install it again?
  2. Have you tried to uninstall or disable your anti-virus?
  3. Have you checked if the camera is enabled (in some computers, you can disable the webcam, like in Lenovo's, with the Fn + F8 key)?
  4. You said that ScreenToGif works well. Do you mean that it can access the webcam normally?
  5. Have you tried to open the Event Viewer to check if any error is popping in there?
  6. Have you checked if you have permissions enabled in the Windows Settings app to other apps to access the webcam?
  7. Have you tried to use other apps that also can access the webcam (other than Camera and Zoom)?
  8. Have you checked if Windows Update is not overriding the driver of your webcam with a generic variant?

Hmm, Frame server...

Have you recently updated Windows 10?

Try disabling FrameServer by downloading the Zip from here (near Download Our One-Click Registry Hack):
https://www.howtogeek.com/267946/how-to-stop-your-webcam-from-freezing-and-crashing-on-windows-10/

Unzip and run the "Enable webcam workaround", 64 bits or 32 bits, depending on your machine.
I checked the registry file and it's safe.

It creates two entries to disable FrameServer.

Awesome. I'm glad it works now.

Well, the link that I provided explains well what is happening.
Also, explains why ScreenToGif still worked, it uses a video mode still supported.

Thanks, the incompatible "update" they made is really shocking, especially for an Anniversary.
