在标签 tkinter 上显示视频大小

Question

以下代码在标签上显示视频。但是，问题在于，它以非常缩放（大）的方式显示。我想调整它的大小以在标签上正确显示。当我使用选项 image=image.resize() 时，出现错误 ValueError: cannot resize this array: it does not own its data

import tkinter as tk, threading
import imageio
from PIL import Image, ImageTk

video_name = "e.mp4" 
video = imageio.get_reader(video_name)
#video = video.resize(20,20)

def stream(label):

    for image in video.iter_data():
        frame_image = ImageTk.PhotoImage(Image.fromarray(image))
        label.config(image=frame_image)
        label.image = frame_image



root = tk.Tk()
my_label = tk.Label(root, width=500,height=500)
my_label.place(x=0,y=0)
thread = threading.Thread(target=stream, args=(my_label,))
thread.daemon = 1
thread.start()
root.mainloop()

您可以在Image.fromarray(image)的返回图片上调用resize()：

frame_image = ImageTk.PhotoImage(Image.fromarray(image).resize((100,100)))
