Question Camera and Webcam Problem - Error: 0xA00F4243 ?

[paulbasel]

I had an older Logitech webcam that worked for years. Then one day, sometime in the last couple of months I noticed it didn't work in Skype (black screen). I tried to find the problem but couldn't. I thought it was defective and bought a new one. Same problem. I tested the new LogiLink LL1 with the camera app and received this error. I should point out that the microphone worked on the old one as well as the new one.

"Close other apps. It looks as though another app is already using the camera. If you need it, here’s the error code: 0xA00F4243 (0xC00D3704)"

I have an Asus M51AC Desktop PC running Win 10 fully updated. I uninstalled the old Logitech software and driver before installing the new webcam.

Here's what I have tried so far with no success:

​

- Ran Malwarebytes - clean​

- Windows driver up to date, no separate driver for this new camera.​

- Ran DISM tools and SFC, fixed a couple of problems. No change.​

- Switched the USB port to one I know functions properly. No change.​

- Device manager shows the "USB Live camera" functioning properly.​

- Disabled all apps at startup, rebooted, no change.​

- Camera access is on. Turned off all apps using the camera. No change.​

- Uninstalled the MS camera app and reinstalled it after a reboot - no change.​

- Ran system troubleshooter, no problems detected.​

- Ran Hardware and Devices troubleshooter, it returned "saskutil and sasdifsv don't have drivers". These are associated with superantispyware. Not important for this problem.​

- Registry: added Dword: EnableFrameServerMode, hex value 0 in the Windows Media Foundation\Platform. Rebooted, no change.​

- Used Process Explorer to find whether any programs were running that used the Physical Device Object name, in my new webcam the object name is: \Device\000000b2. Process Explorer found none even though I had the camera app open as well as the Skype video setting. Refresh frequently, nothing. I believe this process should at least find the two devices that were open and running.​

​

Any help greatly appreciated before I lose all of my hair.​

"Try turning on the three services that I mentioned" I couldn't find the services you mentioned.

could be

Services like Windows Camera Frame Server, Windows Camera Frame Server Monitor, and Windows Image Acquisition power the camera backend in Windows.

These three services, get them all running but don't reboot.

Services: Windows Camera Frame Server, Windows Camera Frame Server Monitor, and Windows Image Acquisition

See if the camera will work with skype and check skype camera settings. You could try a different program like OBS recording software, just remember to allow camera access to it in the windows camera settings.

@KingLoki I did not find the Windows Camera Frame Server Monitor in my list of services. I restarted the other two, did not reboot and opened Skype settings. No video, blank screen. However it does show that it uses my new webcam. I tried OBS recording but at one point it indicated that my Nvidia driver was too old. I couldn't use the recording function.

Can you update your nvidia driver. Its worth trying with another app.
My system has the service in win11pro, that you don't have. Not sure why? What OS are you using?
