Realtek Camera Issues

[ITA94]

Seem to be experiencing an issue with the laptops we're deploying where the onboard webcam (All showing in device manager as "HP 5MP Camera" with the Realtek driver version 10.0.22000.20340) during the Teams meeting is constantly shutting off (white light comes on initially then turns off then their image is frozen until the end of the meeting. Turning off the camera button and enabling again doesn't fix it).

With my testing on another laptop with the same issue, noticing when I use the Camera app to test, when I first launch when the PC comes up, it works, for a bit then freezes and then I can't bring the image back up until I reset the "Camera" app.

Troubleshooting done:
- Uninstalled HP 5MP camera and scanned for hardware changes. Same issue. Even repeated steps and rebooted

- RAN HPIA and updated BIOS and the camera driver, same issue

- These PCs are caught up on Windows updates (They're on W11, 23H2 though. Not sure if a fix for this has been addressed in 24H2 but we won't be able to get that anyway until we actually deploy out, so 23H2 is all we have right now)

- Sent to the HP depot for a repair. They didn't change the hardware, pretty much just reimaged it and ran updates and "Extensive testing". When I got the laptop back from their depot the issue immediately happened again when I tested.

- Added the REGDWORD entry (EnableFrameServerMode, value set to 0) for 64bit systems in location - HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform and in the other location I can't remember atm.

Based on my research aka Google, it seems that what's causing the is between the Windows Camera Frame Server and Windows Camera Frame Server Monitor services. Verified this by running the Cameras app test and going to the windows event viewer. Everytime in the Camera app when it freezes, seeing:

Faulting application name: svchost.exe_FrameServer, version: 10.0.26100.1150, time stamp: 0xfdace0d9
Faulting module name: RsDMFT64.dll, version: 10.0.22000.20340, time stamp: 0x66bdb408

Seems anyone who's researching this issue has reached this point in finding what the cuplrit(s) may or may not be but it stops there. On my test PC, I disabled the "Windows Camera Frame Server Monitor " service and rebooted. It does seem like it helps a bit, freezing isn't happening as much but still occurring, seems the webcam is coming up quicker too. Disabled the Windows Camera Frame Server service as well but then couldn't use the camera at all so left that alone.


Is there anything else I can try out? Seems there's basically no support or workaround for this that's working

Hi @ITA94, 

Welcome to HP Support Community!

We noticed that this thread hasn't had any updates in a while since your original post; while this is rare, we didn't want this post to remain unanswered, so, here's the solution to your query. We hope it helps you and everyone viewing this post 😊

 This Realtek camera issue on the HP ZBook Firefly 14 G11 running Windows 11 23H2 appears to be a known problem, particularly tied to the RsDMFT64.dll module used by the Realtek driver and its interaction with the Windows Camera Frame Server.

Root Cause Summary

The crash logs and behavior suggest a conflict between:

• Realtek Camera Driver (v10.0.22000.20340) — specifically RsDMFT64.dll
• Windows Camera Frame Server (svchost.exe_FrameServer) — which handles camera streams for multiple apps

This is likely a driver compatibility issue with Windows 11 23H2, especially in Teams and Camera app scenarios.

Recommended Steps to Resolve

1. Update to the Latest Realtek Camera Driver (if available)

Check if HP has released a newer version of the Realtek camera driver for your model:

• Go to the HP ZBook Firefly 14 G11 Drivers Page Official HP® Support
• Look under Driver – Camera and download the latest Realtek driver (if newer than 10.0.22000.20340)

2. Temporarily Roll Back to Microsoft UVC Driver

If no newer Realtek driver is available, try using the generic Microsoft USB Video Class (UVC) driver:

• Open Device Manager
• Right-click HP 5MP Camera > Update Driver
• Choose Browse my computer > Let me pick from a list
• Select USB Video Device (Microsoft UVC driver)
• Reboot and test in Teams/Camera app

This bypasses the Realtek DLL (RsDMFT64.dll) entirely.

3. Disable Frame Server Mode (Registry Tweak)

You've already tried this, but ensure both registry paths are updated:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform]
"EnableFrameServerMode"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform]
"EnableFrameServerMode"=dword:00000000

Reboot after applying.

4. Disable “Windows Camera Frame Server Monitor” Service

This has shown partial improvement. You can automate this via Group Policy or a script if deploying to multiple systems.

5. Test with HP Image Assistant (HPIA) Custom Driver Pack

Use HP Image Assistant to:

• Analyze the system
• Download a custom driver pack
• Ensure all firmware, chipset, and camera-related drivers are aligned

Optional Workaround

If Teams is the only affected app, try:

• Disabling hardware acceleration in Teams (Settings > General)
• Using Teams Web App in Edge/Chrome as a temporary workaround
