pyqt5循环mp3文件

Question

我想循环播放音频文件并使用 THIS CODE (my orignal question with solution) and （Qt C 示例）的组合设法创建了这个：

from PyQt5.QtCore import *
from PyQt5.QtMultimedia import *
import sys

if __name__ == "__main__":

    app = QCoreApplication(sys.argv)

    playlist = QMediaPlaylist()
    url = QUrl.fromLocalFile("./sound2.mp3")
    playlist.addMedia(url)
    playlist.setPlaybackMode(QMediaPlaylist.Loop)

    content = playlist()
    player = QMediaPlayer()
    player.setMedia(content)
    player.play()

    app.lastWindowClosed.connect(player.stop)
    app.exec()

然而，这段代码不起作用，报告的错误是：

TypeError：参数与任何重载调用都不匹配： addMedia(self, QMediaContent)：参数 1 具有意外类型 'QUrl' addMedia(self, object)：参数 1 具有意外类型 'QUrl'

我的代码哪里出错了？非常感谢任何帮助。

你很接近。尝试以下...

playlist = QMediaPlaylist()
url = QUrl.fromLocalFile("./sound2.mp3")
playlist.addMedia(QMediaContent(url))
playlist.setPlaybackMode(QMediaPlaylist.Loop)

player = QMediaPlayer()
player.setPlaylist(playlist)
player.play()
