If OBS Virtual Camera shows as “not available” in TikTok LIVE Studio, LIVE Studio can’t find a running virtual camera. Start it in OBS first, then add it in LIVE Studio as a Camera source. If OBS has no button to start it, the virtual camera isn’t installed on that PC, and that’s a two-minute fix.
Here’s the order I’d check, cheapest first.
1. Start the virtual camera before LIVE Studio looks for it
OBS doesn’t send anything until you tell it to. In OBS, click Start Virtual Camera in the Controls dock. The button changes to Stop Virtual Camera once it’s running.
Then, in LIVE Studio:
- Under the scene you’re using, click Add source, then Camera.
- In the camera source settings, use the Camera option to pick OBS Virtual Camera from your connected cameras.
It has to be a Camera source. A different source type won’t list it.
If LIVE Studio was already open when you started the camera, close it and open it again. It’s a cheap second try before you dig any deeper.
2. No “Start Virtual Camera” button? Reinstall it
This is the one most threads skip. A January 2026 report on the OBS forum describes OBS Virtual Camera going “not available” in LIVE Studio right after a laptop factory reset, and updating both apps didn’t bring it back. OBS’s own knowledge base has the fix for a missing virtual camera on Windows: install it again with the script OBS ships.
- Open
C:\Program Files\obs-studio\data\obs-plugins\win-dshow. - Right-click
virtualcam-install.batand choose Run as Administrator.
If you installed OBS somewhere else, or you run the portable version, right-click your OBS shortcut, choose Open File Location, and run virtualcam-install.bat from that install as Administrator instead.
OBS also notes the virtual camera can conflict with other software. The same folder has virtualcam-uninstall.bat, so if it’s installed but still misbehaving, run the uninstall script, then the install script, then restart OBS.
3. Check Windows camera access for desktop apps
Windows can block cameras for apps without saying much about it. Go to Start > Settings > Privacy & security > Camera and check three things:
- Camera access is on. If it’s greyed out, an administrator on that PC has to turn it on.
- Let apps access your camera is on.
- Let desktop apps access your camera is on.
That last one is the one that matters here. Microsoft’s list of per-app switches only covers apps from the Microsoft Store. LIVE Studio comes from TikTok’s own download page, so it falls under the desktop-apps switch, and you can’t allow it on its own. It’s all desktop apps or none.
On Windows 10 the path is Start > Settings > Privacy > Camera, and the switch is called Allow desktop apps to access your camera.
4. It shows up but the picture is wrong
If LIVE Studio lists the camera but shows the wrong thing, check what OBS is sending. Click the gear icon next to the virtual camera button in the Controls dock. OBS gives you four choices:
- Program: whatever OBS is outputting normally.
- Preview: your Preview in Studio Mode, so viewers see your edits as you make them.
- Scene: one scene you pick, no matter what’s live.
- Source: one source you pick.
If you built a scene just for TikTok, Scene keeps the virtual camera on it even while you switch things around in OBS.
Still nothing?
On a Mac. OBS’s virtual camera on macOS 13 and later is a system extension that has to be allowed once. Go to System Settings > Privacy & Security > Security on macOS 13 and 14, or System Settings > General > Login Items & Extensions > Camera Extensions on macOS 15 and later. Click Allow next to the OBS entry, confirm, and restart OBS. On macOS 14, OBS 29.1 and older can’t run the virtual camera at all, so update to OBS 30.0 or newer.
Your real webcam is “in use”. That’s a different problem with the same symptom. On Windows 11, error codes 0xA00F4243 or 0xA00F4289 mean another app has the camera. Microsoft’s fix is to close background apps, or open Task Manager, right-click the app using the camera and choose End Task. Two apps, one webcam, and neither one is going to tell you which of them is holding it.
“Locked.” I couldn’t confirm what a locked virtual camera means in LIVE Studio. TikTok’s help page on camera sources, last updated February 11, 2025, doesn’t mention virtual cameras at all. As of October 2026 there’s no official TikTok word on whether LIVE Studio treats them differently from a webcam, so I’m not going to guess at one.
A note on Campfire Studio
I stream on TikTok LIVE twice a day, and I’m building Campfire Studio, a streaming app that keeps scenes, overlays and alerts for going live from a PC in one place. The beta opens Q4 2026, Free or Pro at $17.99/month. It’s at campfiretales.shop/studio.
Camp is a TikTok LIVE agent with a creator network, streams twice a day, and builds Campfire Studio.
