Kivy video player won't show video, but plays audio

Question

I'm trying to make an application which downloads a video using Pytube, after getting it from a search using youtube-search-python, then playing the video using Kivy's video player. Everything works fine, except for playing the video. Here is my code:

from pytube import YouTube
from kivy.app import App
from youtubesearchpython import VideosSearch
from kivy.uix.videoplayer import VideoPlayer

videosSearch = VideosSearch('心臓を捧げよ！', limit = 1)

for i in range(1):
    download_link = videosSearch.result()['result'][i]['link']
    

yt = YouTube(download_link)
yt.streams.get_highest_resolution().download()
video = (yt.title) + '.mp4'

class Player(VideoPlayer):
   player = VideoPlayer(source= video, state = 'play')


class VideoApp(App):
    def build(self):
        return Player()


if __name__ == '__main__':
    VideoApp().run()

and here is my output:

I installed ffpyplayer after seeing that worked for some people with a slightly different error. Doing so caused me to get audio, but still no video.

Answer 1

Try replacing:

return Player()

with:

return VideoPlayer(source= video, state = 'play')

and eliminate the Player class.
