Question: Does it only work if camera is infrared?

Does it only work if camera is infrared?
I have an issue where the green circle eye tracking keeps going all over the place.

EDIT:
I also tested with your own video
OrloskyPupilDetectorRaspberryPi.py
replacing
cap = cv2.VideoCapture(0)
with
cap = cv2.VideoCapture('eye_test.mp4')

But the bounding green circle jumping all over the place still persists.

Hello, I also encountered this problem when loading video files to run
May I ask if it has been resolved
