Python vlc警告信息格式

上面的代码是使用pyuic5语句生成的。 我只添加了以下几行：

进口vlc

definit方法

当我运行程序时，它输出：

[000001e1917c4fa0]mm设备音频输出错误：无法初始化COM（错误0x80010106）

两次

通过此程序：

# -*- coding: utf-8 -*-

from PyQt5 import QtCore, QtGui, QtWidgets
import vlc

class Ui_Form(object):
    def __init__(self):
        self.Instance = vlc.Instance(['--no-xlib'])
        self.player = self.Instance.media_player_new()

    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(400, 300)

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

不输出任何内容

第一个代码怎么了

import vlc

Instance = vlc.Instance(['--no-xlib'])
player = Instance.media_player_new()
