Kivy Video Player-未加载视频

我正在尝试使用这个简单的示例使用Kivy播放视频:

from kivy.app import App
from kivy.uix.videoplayer import VideoPlayer


class TestApp(App):
    vid = None

    def replay(self, instance, value):
        if value != "play":
            # self.vid.play = True
            self.vid.state = "play"

    def build(self):
        self.vid = VideoPlayer(source="./S02E02.mp4", state="play")
        # self.vid.bind(state=self.replay)  # When state changes, if not playing, play it
        return self.vid


TestApp().run()

但是视频未加载并播放。我将其作为输出:

视频文件S02E02.mp4与python脚本位于同一目录中。

我使用的kivy版本是1.10.1,带有Python 3.6和Ubuntu 18.04。

有人知道发生了什么事吗?

解决方案

将用户添加到“输入”组:

$ sudo adduser $USER input

注意 您需要先注销然后重新登录才能应用这些权限。
