I started messing with that but found obs.ninja easier to use with better results. Then again, I already use OBS' virtual camera as the source in my conferences, if only for basic resizing and color correction of my mediocre webcam. Ended up not using it after a while because I didn't like the way the phone still gets pretty warm after an hour or two conference (same as DroidCam et al).
