How to start the OBS virtual camera when Zoom or Teams opens

Create a KeyRoutines routine with App launched and App quit triggers for Zoom or Teams. On launch, Open app opens OBS, a Wait until with OBS is connected waits for it, OBS: switch scene picks your call scene and OBS: record / stream / replay starts the virtual camera; on quit, it stops it.

Steps

1. 1

   Watch the call app

   Add App launched and App quit for Zoom, Teams or both.

2. 2

   Branch

   Add an If with Started by trigger set to App launched.

3. 3

   Open OBS and wait

   In the If branch, add Open app for OBS, minimized if you like, and a Wait until with OBS is connected.

4. 4

   Start the virtual camera

   Add OBS: switch scene with your call scene, then OBS: record / stream / replay set to start the virtual camera.

5. 5

   Stop after the call

   In the Else branch, add OBS: record / stream / replay set to stop the virtual camera.

Tips

• Pick OBS Virtual Camera as the camera in Zoom or Teams once; after that it's there whenever the routine starts it.
• App quit fires when the app's last process ends, so closing one Teams window doesn't stop the camera.
