I have written this little python script to play a sound using Phonon.
(I originally posted it here)

I find it useful because it doesn't conflict with amarok or any application that uses Phonon (the other command-line utils I saw tried to use alsa directly)

Hope you like it. I called it 'phonon-play' and made an alias named 'pplay' to execute the script.

Code: Select all

#! /usr/bin/env python
from PyQt4.phonon import Phonon
from PyQt4.QtGui import QApplication
from PyQt4.QtCore import SIGNAL, SLOT
from PyQt4.QtCore import QFile
import sys
import signal


def main():
    signal.signal(signal.SIGINT, signal.SIG_DFL)
    app = QApplication(sys.argv)
    QApplication.setApplicationName('phonon-play')

    media = Phonon.MediaObject()
    audio = Phonon.AudioOutput(Phonon.MusicCategory)
    Phonon.createPath(media, audio)
    f = QFile(sys.argv[1])
    if f.exists():
        source = Phonon.MediaSource(sys.argv[1])
        if source.type() != -1:              # -1 stands for invalid file
            media.setCurrentSource(source)
            app.connect(media, SIGNAL("finished()"), app, SLOT("quit()"))
            media.play()
            return app.exec_()
        else:
            return -2
    else:
        return -1

if __name__ == '__main__':
    sys.exit(main())


Just out of curiosity: does it need the QApplication from QtGUI or could it also just use QCoreApplication from QtCore?

By looking at the Phonon documentation, on doc.qt.nokia.com, it seems that it should be possible in theory to use QCoreApplication as none of the used classes are GUI classes.

I'm a real noob here, you are probably absolutely right. Since it worked well, I left it as it is...

Thanks, this is really useful!

Fixed the Pnonom -> Phonon for the sakes of searching.

i prefer using xmms2 for playing audio files via command line

Aweome tip mate, thanks.

Just signed up and already seeing the value here.

I am a bit overwhelmed with the great info but will catch up and hopefully contribute more soon.

Indeed, replacing the occurrence of QtGUI with QtCore and changing all QApplication to QCoreApplication still made my computer play the soundfile I passed to phonon-play.py

I was looking for this thank
