如何用 QtMultimedia 編寫上述代碼?

How do I write the above code with QtMultimedia?

你能舉個例子嗎?

推薦答案

如果文件是 .wav 則只需使用 QSound:

If the file is a .wav then just use QSound:

import os
import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))


def main():
    filename = os.path.join(CURRENT_DIR, "beal.wav")

    app = QtCore.QCoreApplication(sys.argv)

    QtMultimedia.QSound.play(filename)


    # end in 5 seconds:
    QtCore.QTimer.singleShot(5 * 1000, app.quit)

    sys.exit(app.exec_())


if __name__ == "__main__":
    main()

如果你想播放更多格式，那么你應該使用 QMediaPlayer:

If you want to play more formats then you should use QMediaPlayer:

import os
import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))


def main():
    filename = os.path.join(CURRENT_DIR, "sound.mp3")

    app = QtCore.QCoreApplication(sys.argv)

    player = QtMultimedia.QMediaPlayer()

    def handle_state_changed(state):
        if state == QtMultimedia.QMediaPlayer.PlayingState:
            print("started")
        elif state == QtMultimedia.QMediaPlayer.StoppedState:
            print("finished")
            QtCore.QCoreApplication.quit()

    player.stateChanged.connect(handle_state_changed)

    url = QtCore.QUrl.fromLocalFile(filename)
    player.setMedia(QtMultimedia.QMediaContent(url))
    player.play()

    sys.exit(app.exec_())


if __name__ == "__main__":
    main()
