Question

我正在使用Kivy视频组件在屏幕上播放公司视频，当我第二次停止播放它时，会导致应用程序挂断。

经过调试以尝试解决问题后，我发现它们挂在video_gstplayer.py中：

def seek(self, percent, precise=True):
    self.player.seek(percent)

恰好在第二句话上；而前一个来自video.py：

def on_state(self, instance, value):
    if not self._video:
        return
    if value == 'play':
        if self.eos:
            self._video.stop()
            self._video.position = 0.
            self._video.eos = False
        self.eos = False
        self._video.play()
    elif value == 'pause':
        self._video.pause()
    else:
        self._video.stop()
        self._video.position = 0
        self._video.eos = False

并完全跳到最后一个self._video.position = 0。

我使用视频和窗口小部件的代码如下：

class Presentation(Screen):

    def v_player(self):
        if App.get_running_app().play == 0:
            App.get_running_app().play = 1
            App.get_running_app().video = Video(source='data/video/video.mp4')
            App.get_running_app().video.state = 'play'
            App.get_running_app().video.allow_stretch = True
            self.add_widget(App.get_running_app().video)
        else:
            App.get_running_app().play = 1

    def go_inicio(self):
        if App.get_running_app().play == 1:
            App.get_running_app().play = 0
            App.get_running_app().video.state = 'stop'
            self.remove_widget(App.get_running_app().video)
            sm.current = 'inicio'
        else:
            App.get_running_app().play = 0
            sm.current = 'inicio'
    pass

我通过单击调用函数go_inicio的“后退”按钮来停止视频。

App类的实现：

class GlomarkHome(App):
   slide_pro = 0
   slide_lit = 0
   play = 0
   video = 0

  def build(self):
     sm.add_widget(Inicio(name='inicio'))
     sm.add_widget(Categoria(name='categoria'))
     sm.add_widget(Presentation(name='presentation'))
     sm.add_widget(Productos(name='productos'))
     sm.add_widget(Obras(name='obras'))
     sm.add_widget(Pgrid(name='pgrid'))
     sm.add_widget(Pgrid_obras(name='pgrid_obras'))
     sm.add_widget(Product_1(name='product_1'))
     sm.add_widget(Product_2(name='product_2'))
   return sm
pass

有什么主意吗？
