Expected Behavior

After installing OBS Virtual Camera, it should appear in Windows Settings →
Bluetooth & devices → Cameras and be selectable in apps like Windows Camera.

Current Behavior

OBS Virtual Camera does not appear in Windows 11 22H2+ camera settings or any camera-enabled
app, despite successful installation. Both DLLs register without error via regsvr32,
and the CLSID is correctly present in the registry under:
HKLM\SOFTWARE\Classes\CLSID{A3FCE0F5-3493-419F-958A-ABA1250EC20B}

Steps to Reproduce

1. Install OBS Studio on Windows 11 22H2+
2. Open OBS → Tools → Virtual Camera → Start Virtual Camera
3. Open Windows Settings → Bluetooth & devices → Cameras
4. OBS Virtual Camera is not listed

Anything else we should know?

Root cause: Windows 11 22H2+ requires the EnableFrameServerMode registry key to be set for
virtual cameras to be recognized by the new Windows Media Foundation camera framework.
This key is not set by the OBS installer.

Fix that resolved the issue:

reg add "HKLM\SOFTWARE\Microsoft\Windows Media Foundation\Platform" /v EnableFrameServerMode /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform" /v EnableFrameServerMode /t REG_DWORD /d 1 /f

After running both commands and restarting, OBS Virtual Camera appeared correctly in
Windows Settings and all apps.

Suggestion: the OBS Virtual Camera installer should automatically set
EnableFrameServerMode=1 on Windows 11 to prevent this issue for other users.

The OBS virtualcamera is not a mediafoundation device, it's a directshow device, and it is working just fine for me across all applications on Windows 11 on a version far newer than 22H2.

Can you please point to the official documentation or explain how you reached this conclusion?
