How can the source of the video player in Kivy be replaced and the previous source be removed?

edit

To replace the source of the video player in Kivy and remove the previous source, you can use the unload() method to remove the previous source and then set the new source using the source property of the video player.

Here is an example code snippet:

# Import necessary modules
from kivy.uix.video import Video

# Create a video player object
video_player = Video()

# Set the initial source of the video player
video_player.source = 'path/to/previous/video.mp4'

# Unload the previous video source
video_player.unload()

# Set the new source of the video player
video_player.source = 'path/to/new/video.mp4'

In this example, we create a Video object and set its initial source to a video file. Then we use the unload() method to remove the previous source and set the new source using the source property.
