Question

我尝试使用libvlc在python 3中制作一个播放器，以使播放器具有播放列表，音轨和音频输出通道选项，但是我在使用文档时遇到了麻烦。我希望有人可以帮助我：

制作播放列表，
获取并设置音轨，
并设置auido频道

谢谢

        keyboard.add_hotkey("l",self.audioleft)
        keyboard.add_hotkey("r",self.audioright)
        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)
        #self.audio()

    def butt(self):
        if self.mediaplayer.is_playing():
            print("pause")
            self.mediaplayer.pause()
        else:
            print("play")
            self.mediaplayer.play()

    def audioleft(self):
        print("L")
        self.au.AudioOutputChannel.Left()

    def audioright(self):
        print("R")
        self.au.AudioOutputChannel.Right()

    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_())

我阅读了有关更改音频输出通道的文档，但使用的是AudioOutputChannel类，但我无法尝试这样做并导致错误。

如何在python vlc中获取音频输出通道和音轨
