Question

During the Olympic Games there is a channel with official broadcast of the event and for Smart TV they have four livestreams to create the Mosaic Mode:

https://www.youtube.com/live/y6hH0cyJd3g

But I want to use these lives to create a Mosaic Mode on the computer, so I tried:

import tkinter as tk
import vlc
import pafy

class YouTubeMosaic:
    def __init__(self, root):
        self.root = root
        self.root.title("YouTube Mosaic")
        self.videos = []
        self.instances = []
        self.create_widgets()

    def create_widgets(self):
        self.entry_frame = tk.Frame(self.root)
        self.entry_frame.pack(side=tk.TOP)

        self.entries = []
        for i in range(4):
            entry = tk.Entry(self.entry_frame, width=50)
            entry.pack(side=tk.LEFT)
            self.entries.append(entry)

        self.play_button = tk.Button(self.entry_frame, text="Play", command=self.play_videos)
        self.play_button.pack(side=tk.LEFT)

        self.video_frame = tk.Frame(self.root)
        self.video_frame.pack(fill=tk.BOTH, expand=True)

        self.video_frames = []
        for i in range(2):
            for j in range(2):
                frame = tk.Frame(self.video_frame, width=400, height=300, bg='black')
                frame.grid(row=i, column=j, padx=5, pady=5)
                self.video_frames.append(frame)

    def play_videos(self):
        for i in range(4):
            url = self.entries[i].get()
            if url:
                self.play_video(url, self.video_frames[i])

    def play_video(self, url, frame):
        video = pafy.new(url)
        best = video.getbest()
        play_url = best.url

        instance = vlc.Instance()
        player = instance.media_player_new()
        media = instance.media_new(play_url)
        media.get_mrl()
        player.set_media(media)
        player.set_hwnd(frame.winfo_id())

        player.play()
        self.videos.append(player)
        self.instances.append(instance)

if __name__ == "__main__":
    root = tk.Tk()
    app = YouTubeMosaic(root)
    root.mainloop()

I’ve tried everything I can imagine, I’ve followed all the instructions and ideas I could find to give a basis for the idea, but in the end, I always end up getting this same error that I don’t know how to solve:
