Hi guys, early 2026 here and if this problem wasn't resolved for you. I think I found a fix(?) or something that might worth attention.
Here is my story, if you don't want to, just skip this whole paragraph and go down to "
instructions", so anyways, I stumbled across this forum on my research since I have the same problem when I try to use virtual camera on zoom, the comment from KrayKrayPapa hinted that it has something to do with the architecture. And I found my solution as I went down this direction.
The problem was happening for me because my machine is ARM64, which OBS does have different versions of virtual camera for emulated x64 (AMD) and native ARM64, this article shows me:
https://obsproject.com/kb/windows-on-arm#virtual-camera
The moment I realized this, I figured I need the right version of Zoom and I need to enable the ARM version of virtual camera. So to test it out, I grabbed the ARM64 version from Zoom's website, and followed the instructions on the said page after I downloaded the "OBS-Studio-32.0.4-Windows-arm64.zip" for the corresponding dll needed (since I can't find obs-virtualcam-module-arm64.dll in the install, probably applies to everyone).
Restart, and it worked! Now Zoom detects and uses OBS virtual camera just like how I used it comfortably on my AMD64 PC.
Ok, here's the
instructions:
1. Download the corresponding arm64.zip pack from OBS' Github page
2. in the .zip, navigate to "data\obs-plugins\win-dshow\"
, copy and paste "obs-virtualcam-module-arm64.dll" to your obs installation's "data\obs-plugins\win-dshow\"
3. Following the instructions on "https://obsproject.com/kb/windows-on-arm#virtual-camera",
- run "regsvr32.exe /i /u obs-virtualcam-module64.dll"
- then run "regsvr32.exe /i /s obs-virtualcam-module-arm64.dll"
4. Restart just to make sure everything is loaded, if your target application has a native x64 version like Zoom, install and use that version.
5. There you go, your target application hopefully works with OBS virtual camera.
(So far this "modification" method on OBS for ARM64 systems, I only tested it worked for Zoom(ARM version) and MSTeams (x64 emulated, so if you'd like to test this on other applications and have results, feel free to share)
Bonus:
While on my way to trying to make Zoom work, I discovered a workaround application for ARM64 PCs called "Camo Studio", it works like virtual camera, but not as detailed and flexible, but if you are desperate, this may be a solution since it supports no watermark, window capture, pictures and another webcam input source. You can drag the elements around like a scenario so I'd say it's a fair workaround solution.
