I've attempted to modify this script here, but instead of for 4 video outputs, to only 2. I'm pretty new to programming a pi and am trying to wrap this up for an gallery project. Here is my current script. The video plays currently, but get stuck at the 102 second mark. What I am attempting to do is have a video of an eye closed when in idle state, but when motion is sensored, to have the eye appear to open and look around. Any help is appreciated.

from pathlib import Path

import RPi.GPIO as GPIO #for taking signal from GPIO

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)

GPIO_PIR = 7 #The GPIO is plugged into BCM pin 07 (GPIO pin 26)
GPIO.setup(GPIO_PIR,GPIO.IN) # Set pin as input
 
Current_Motion  = 0 #the current state of motion detection
Previous_Motion = 0 #the previous state

birdname = "goldfinch"
VIDEO_PATH = Path("/media/pi/ASTEYES/sensor_py_birds.mp4")

player = OMXPlayer(VIDEO_PATH)

This should work:

Remember to replace the ENDOV variable with the time that the video ends
