Question

在py中

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder

Builder.load_string('''                
<Test_win>:
    VideoPlayer:
        source: 'test.mp4'
        eof: 'stop'
''')

class Test_win(BoxLayout):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

class VidApp(App):
    def build(self):
        return Test_win()

if __name__=="__main__":
    app =VidApp()
    app.run()

视频播放器成功运行，但是直到视频结束，我都不能再播放它了（崩溃）。当我单击停止按钮时，它也会崩溃。

在此之前，我已经删除了“共享”文件夹的Gstreamer，并替换为ffpyplayer（在提示符下键入set KIVY_VIDEO=ffpyplayer）。
