can you write a python script that displays an rtsp stream on a 320x240 display on fullscreen for 30 seconds?
 Sure! Here is a simple Python script using the OpenCV library to display an RTSP stream on a 320x240 display in fullscreen mode for 30 seconds:
```python
import cv2
import time

# Set the RTSP stream URL here
stream_url = 'rtsp://your_rtsp_stream_url'

# Create a VideoCapture object to read the RTSP stream
cap = cv2.VideoCapture(stream_url)

# Set the display window size to 320x240
cv2.namedWindow('RTSP Stream', cv2.WINDOW_NORMAL)
cv2.resizeWindow('RTSP Stream', 320, 240)

# Set the start time
start_time = time.time()

while True:
    # Read a frame from the RTSP stream
    ret, frame = cap.read()

    # If the frame was successfully read
    if ret:
        # Display the frame in fullscreen mode
        cv2.setWindowProperty('RTSP Stream', cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)
        cv2.imshow('RTSP Stream', frame)

        # If 30 seconds have passed, break the loop
        if time.time
import time
import cv2

# capture an rtsp stream
capture = cv2.VideoCapture('rtsp://admin:admin@192.168.1.100/stream1')

# set up the display
width, height = 320, 240
display = cv2.VideoDisplay(width, height, 'Fullscreen')

# start the stream
capture.start()

# wait 30 seconds
time.sleep(30)

# stop the stream
capture.stop()

# show the stream on the display
display.show()
