如何使用图像序列在tkinter上显示视频

import cv2
import tkinter as tk
from PIL import Image, ImageTk

window = tk.Tk()
canvas = tk.Canvas(window, width=640, height=480)
canvas.pack()

def show_frame():
    ret, frame = cap.read()  # 读取视频帧
    if ret:
        frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)  # 转换颜色空间
        image = Image.fromarray(frame)  # 创建PIL图像对象
        photo = ImageTk.PhotoImage(image)  # 创建tkinter图像对象
        canvas.create_image(0, 0, image=photo, anchor=tk.NW)  # 在画布上显示图像
        window.after(10, show_frame)  # 每10毫秒更新一次图像
    else:
        cap.release()  # 释放视频资源

cap = cv2.VideoCapture('video.mp4')  # 打开视频文件
# cap = cv2.VideoCapture(0)  # 启动摄像头

show_frame()

import cv2
import tkinter as tk
from PIL import Image, ImageTk

window = tk.Tk()
canvas = tk.Canvas(window, width=640, height=480)
canvas.pack()

def show_frame():
    ret, frame = cap.read()
    if ret:
        frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
        image = Image.fromarray(frame)
        photo = ImageTk.PhotoImage(image)
        canvas.create_image(0, 0, image=photo, anchor=tk.NW)
        window.after(10, show_frame)
    else:
        cap.release()

cap = cv2.VideoCapture('video.mp4')
# cap = cv2.VideoCapture(0)

show_frame()

window.mainloop()
