Thread exception when switching video file

[matou1604]

Hi Paul, I have seen other people with the same problem, but cannot seem to solve it.

I am curretly coding a videoplayer GUI that is able to switch to previous and next videos through buttons. When the Next or Previous buttons are pushed once the video is finished, no error comes up. But when the Next or Previous button interrupt the video playing, I get this error:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "C:\Users\Karin\anaconda3\envs\tk_clone\lib\threading.py", line 980, in _bootstrap_inner
    self.run()
  File "C:\Users\Karin\anaconda3\envs\tk_clone\lib\threading.py", line 917, in run
    self._target(*self._args, **self._kwargs)
  File "C:\Users\Karin\anaconda3\envs\tk_clone\lib\site-packages\tkVideoPlayer\tkvideoplayer.py", line 201, in _load
    self._container.close()
AttributeError: 'NoneType' object has no attribute 'close'

I have tried adding after(), and it helps (in the sense that the video player no longer freezes), but I still get the error message.

Thanks in advance for your precious help,

Mathilde :)

PS: here is a reproducible example:

import tkinter as tk
from tkVideoPlayer import TkinterVideo
import os

class VideoPlayerApp:
    def __init__(self, root, video_folder):
        self.root = root
        self.video_folder = video_folder
        self.video_list = self.get_video_list()
        self.current_video_index = 0

        self.setup_ui()
        self.play_video(self.video_list[self.current_video_index])

    def get_video_list(self):
        video_extensions = ('.mp4', '.avi', '.mov', '.mkv')
        return [os.path.join(self.video_folder, f) for f in os.listdir(self.video_folder) if f.endswith(video_extensions)]

    def setup_ui(self):
        self.root.title("Video Player")
        self.root.geometry("800x600")

        self.vid_player = TkinterVideo(master=self.root, bg="black")
        self.vid_player.pack(expand=True, fill="both")

        self.control_frame = tk.Frame(self.root)
        self.control_frame.pack(fill="x")

        self.prev_button = tk.Button(self.control_frame, text="Previous", command=self.prev_video)
        self.prev_button.pack(side="left")

        self.play_pause_button = tk.Button(self.control_frame, text="Play/Pause", command=self.play_pause)
        self.play_pause_button.pack(side="left")

        self.next_button = tk.Button(self.control_frame, text="Next", command=self.next_video)
        self.next_button.pack(side="left")

    def play_video(self, video_path):
        try:
            print("Stopping current video...")
            self.vid_player.stop()
            print(f"Loading new video from path: {video_path}")
            self.vid_player.load(video_path)
            print("Playing new video...")
            self.vid_player.play()
            #self.vid_player.after(100, lambda: self.vid_player.play())
        except Exception as e:
            print(f"Error loading video: {e}")

    def play_pause(self):
        if self.vid_player.is_paused():
            self.vid_player.play()
        else:
            self.vid_player.pause()

    def next_video(self):
        self.current_video_index = (self.current_video_index + 1) % len(self.video_list)
        self.play_video(self.video_list[self.current_video_index])

    def prev_video(self):
        self.current_video_index = (self.current_video_index - 1) % len(self.video_list)
        self.play_video(self.video_list[self.current_video_index])

if __name__ == "__main__":
    root = tk.Tk()
    video_folder = "video_folder"  # Replace with the path to your folder containing videos
    app = VideoPlayerApp(root, video_folder)
    root.mainloop()

Hey thanks @matou1604 , it's actually a bug, it might take some time to fix, since I'll be busy for next couple of months. Once I find time, I'll fix it up along with some features. Until then use a workaround mentioned here:#54

Thanks!
