Is there a way to enable face tracking when the camera is set to portrait orientation?

[YuNoJuly]

I'm using OBS with the face tracking feature, but I'm encountering issues when setting up my camera in portrait orientation. The face tracking doesn't seem to function correctly in this mode. I've tried rotating the camera, but tracking remains unstable.

How do you set your camera in portrait? What is your camera? Which filter or source type did you use, as this plugin provides 3 types?
