python中的屏幕录像机生成多个帧

如何解决python中的屏幕录像机生成多个帧

我找到了应该是tp记录屏幕的代码。这是代码

import cv2
import numpy as np
import pyautogui

# display screen resolution,get it from your OS settings
SCREEN_SIZE = (1280,1024)
# define the codec
fourcc = cv2.VideoWriter_fourcc(*"XVID")
# create the video write object
out = cv2.VideoWriter("output.avi",fourcc,20.0,(SCREEN_SIZE))

while True:
    # make a screenshot
    img = pyautogui.screenshot()
    # img = pyautogui.screenshot(region=(0,300,400))
    # convert these pixels to a proper numpy array to work with OpenCV
    frame = np.array(img)
    # convert colors from BGR to RGB
    frame = cv2.cvtColor(frame,cv2.COLOR_BGR2RGB)
    # write the frame
    out.write(frame)
    # show the frame
    cv2.imshow("screenshot",frame)
    # if the user clicks q,it exits
    if cv2.waitKey(1) == ord("q"):
        break

# make sure everything is closed when exited
cv2.destroyAllWindows()
out.release()

该代码有效，但是对于Output.avi文件，在观看它时，我注意到录制的屏幕中出现了多个帧。此外，在开始记录时如何最小化应用程序（.py）？
