The OBS Virtual Camera is a powerful tool for streaming professional video into calls, but it can be frustrating when it doesn't appear in Microsoft Teams or Zoom. This problem is common and usually stems from software conflicts, incorrect startup order, or permission issues. This comprehensive guide will walk you through step-by-step fixes for both Windows and macOS to get your virtual camera working reliably.

Quick Diagnosis: What's Your Specific Problem?
Identifying your exact symptom helps target the right fix. Here are the most common scenarios:
Symptom A: The "OBS Virtual Camera" option is completely missing from the camera list in Teams or Zoom.
This is often a startup order, permission, or driver issue. Start with the Universal Fixes below.
Symptom B: The option is there, but you see a black screen, the OBS logo, or a frozen image.
This usually means OBS is running, but the feed isn't passing through correctly. Check the Zoom & Teams-Specific Tips and ensure OBS is not minimized.
Symptom C: It works sometimes but crashes or freezes.
This often points to a software conflict, an outdated version, or a known bug in a specific update of OBS, Teams, or Zoom.
Universal Fixes (Work on Windows & Mac)
Always begin with these foundational steps. They resolve the majority of issues.
- Follow the Correct Startup Order: A critical and often overlooked step is to always start OBS and activate the Virtual Camera BEFORE opening Teams or Zoom. Fully quit the meeting apps, then launch OBS, click "Start Virtual Camera," and only then open your meeting software.
- Restart Everything Properly: Don't just close apps. Fully quit Teams/Zoom from the system tray or Activity Monitor. For OBS on Windows, use Task Manager to "End Process Tree" to ensure all components close. Then restart your computer—many users report this alone fixes the issue.
- Update Your Software: Ensure you are running the latest versions of OBS Studio, Teams, and Zoom. Bugs that break Virtual Camera compatibility are frequently patched in updates.
- Check OBS Virtual Camera Settings: In OBS, click the "Settings" gear next to the "Start Virtual Camera" button. Ensure the output is set to "Program (Default)" if you are using Studio Mode, or to your specific scene source if not.
In-Depth Windows Troubleshooting
If the universal fixes don't work, proceed with these Windows-specific solutions.
- Run OBS as Administrator: Right-click the OBS Studio shortcut and select "Run as administrator." This grants it the necessary permissions to create a virtual device.
- Check Camera Privacy Settings: Go to Windows Settings > Privacy & security > Camera. Ensure "Camera access" is ON and that both "Let apps access your camera" and "Let desktop apps access your camera" are enabled.
- Disable Conflicting Software: Other apps like Discord, game overlays (Xbox Game Bar), or camera control suites can claim exclusive camera access. Close them via Task Manager.
- Address Known Bad Updates: There is a known issue with OBS version 27.2.2 causing black screens. If you are on this version, update to the latest release or revert to 27.2.1. Similarly, some Zoom updates have broken compatibility—try a manual update or reinstall from the official site.
In-Depth macOS Troubleshooting
macOS has its own set of security and compatibility hurdles for virtual cameras.
- Grant Camera Permissions: Go to System Settings > Privacy & Security > Camera. Ensure both OBS Studio and the app you're using (Zoom or Teams) are checked in the application list. You may need to quit and reopen them after enabling permissions.
- Use the Built-in Virtual Camera: Ensure you are using OBS Studio version 28.0 or newer, which includes a native, more compatible virtual camera for macOS. Avoid using the old third-party "obs-mac-virtualcam" plugin.
- Teams-Specific Fix (Advanced): A recurring issue on Mac involves Microsoft Teams' application signature. A workaround posted on the Microsoft community involves removing and re-establishing the signature via Terminal commands. Note: This is a technical fix and may need to be repeated after Teams updates.
Zoom & Teams-Specific Tips
- For Zoom: If you see a black screen, try this quirky but effective workaround: With OBS Virtual Camera selected in Zoom, enable and then disable Zoom's "Touch up my appearance" or "Blur my background" feature. This can force Zoom to reacquire the video feed.
- For Both Apps: Don't just switch cameras within the call. Go into the app's Settings > Video/Devices menu to select "OBS Virtual Camera" as the default device before joining a meeting.
- For Browser-Based Meetings: If using Teams or Zoom in a browser (like Chrome or Edge), try disabling "Hardware Acceleration" in the browser's settings. This can resolve conflicts with virtual camera access.
What to Try If Nothing Else Works
- Clean Reinstall OBS: Uninstall OBS, download the latest installer from the official OBS website, and perform a fresh install.
- Use a Dedicated Virtual Camera App: Consider using a dedicated virtual camera tool like ManyCam or CamTwist, which can be set as a source in OBS and may have better compatibility with some apps.
- Screen Share as a Last Resort: As a functional workaround, in your meeting app, share your screen/window instead of using the camera. In OBS, enable "Projector (Preview)" on your scene and share that window.
Frequently Asked Questions (FAQ)
Why does the OBS Virtual Camera work in some apps but not in Teams/Zoom?
Teams and Zoom are more aggressive in how they access camera devices and can sometimes lock them exclusively or have stricter security checks (especially on macOS). The startup order is also more critical with these apps.
I'm sure I'm doing everything right, but it's still not showing up. What now?
Focus on conflicts. Use Task Manager (Windows) or Activity Monitor (Mac) to end all non-essential processes, especially other communication, streaming, or camera software. Then try the startup order again. Also, verify you are using a modern, stable version of OBS and not a beta release.
Do I need to install a separate plugin for the Virtual Camera?
No. For several years now, the Virtual Camera feature has been built directly into OBS Studio. You do not need a separate plugin. If an older guide tells you to install one, it is outdated. Always get OBS from the official source.
Is there a way to permanently fix the Teams issue on Mac?
The core issue lies with Microsoft Teams' compatibility with macOS security frameworks. There is no user-controlled permanent fix. The solution often involves waiting for Microsoft to update Teams or using the browser version, which typically handles virtual cameras better[citation:6].
