[Gorashy]

I am trying to play video, the video is playing on the background only and no window is shown. this the function that plays the video in a class.

class Firstwindow(Screen):
    def on_pre_enter(self,*args):
        video= VideoPlayer(source ='react.mp4')
        video.state ='play'
        video.allow_fullscreen=True
        return video

kv file
