Dell Latitude 5450 camera is not working

Hello,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
Could you please try re-installing the Camera Drivers and see if it resolves this issue?
If the camera app displays an image after restarting your computer and when switching between the camera functions, it's likely that some other application is using your camera. Ensure you disable all the startup apps in the task manager and reinstall the drivers to see if this helps resolve the issue.
1. Open the Device Manager (Click Windows + X).
2. Expand the arrow next to Cameras.
3. Right-click your Integrated Camera Driver, select Uninstall device, select the Attempt to remove the driver for this device check box, and then select Uninstall.
4. Once uninstalled, restart your PC.
(Windows will automatically re-install the drivers for your PC).
5. Test your camera functions after the system restart.
If you still have problems, I suggest trying the solutions provided by your PC manufacturer's website to see if they help.

Make sure your camera frame server service is set on and start up automatically.

We had a similar issue.
Also this Reg key needs to be set:
HKEY_LOCAL_MACHINE \SOFTWARE\Microsoft\Windows Media Foundation\Platform

DWord EnableFrameServerMode Value 1. You may also be able to fully delete the key.

I also found that the Intel AV Camera driver from June 24 is best. .

Go check out this Camera firmware relase from Dell.

It's not available anymore !

Interesting. This is the same firmware (to be clear, not a driver, so to speak :)

What do you mean by, "I am in the process of building brand new Dell Latitude 5450 laptops"? Do you work for Dell?

What you say you are doing could be a crime, especially if you try to sell the computers claiming they are brand new.

Expect to hear from Dell about this.

LOL -- he probably just means 'building out' (as in, for deployment) :P

Laugh all you want, as a retired Texas Peace Officer, I take it seriously. Dell is just down the highway from where I live. I also own all Dell computers.

Yeah but you have just assumed they're committing some sort of fraud, I think you're taking it *too* seriously.

Exactly. :)
