Restarting other apps, OBS itself, or the whole system seems to have no effect on the red screen issue.

Did that code get lost or changed in the 29.x development branch? My system also suffered red screen video output in a previous 28.x version, but presumably #7403 fixed it in a later 28.x version, and it's been working fine in the latest 28.1.2.

This appears to be a regression of #7333. Note that the video is solid red when viewed in other apps like Google Chrome.Note that the video looks fine in OBS itself.Enter system credentials to allow the system to install the new version of the mac-virtualcam plugin.Either upgrade from 28.1.2 to 29.0.0 via the in-app upgrade prompt, or manually download the new version directly from (I tried both with the same result).Use old OBS (28.1.2) with normal working virtual camera.When virtual cam is disabled, it shows the normal placeholder graphic. Current BehaviorĪny other app using the virtual camera shows a bright red screen when the virtual cam is enabled. Virtual camera should show the currently selected output scene.
