tkinter播放视频问题

Question

参考tkinter 界面播放视频
我按这个写，把视频播放成了3倍速，一下子没了

from tkinter import *
from PIL import ImageTk, Image
import cv2

root = Tk()
app = Frame(root, bg="white")
app.grid()
lmian = Label(app)
lmian.grid()
cap = cv2.VideoCapture('a1.mp4')
def video_stream():
    _, frame = cap.read()
    cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
    img = Image.fromarray(cv2image)
    imgtk = ImageTk.PhotoImage(image=img)
    lmian.imgtk = imgtk
    lmian.configure(image=imgtk)
    lmian.after(1, video_stream)
video_stream()
root.mainloop()

python3.11.4 Pillow:10.0.0
