I been trying all day to figure out the Qt's Phonon library with Python.

My long term goal is to see if I could get it to play a mms:// stream, but since I can't find an implementation of this done anywhere, I will figure that part out myself. (figured I'd put it out there if anyone knew more about this specifically, if not no big deal.)

Anyway, I figured I'd work backwards from a working example I found online. This launches a file browser and will play the mp3 file specified. I wanted to strip out the file browser stuff and get it down to the essentials of executing the script and having it play an Mp3 file with a hardcoded path.

I'm assuming my problem is a misunderstanding of setCurrentSource() and specifying the data types. (see: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/phonon-mediasource.html#fileName)

I'm keeping my question kind of broad because ANY help with understanding Phonon would be greatly appreciated.

from PyQt4.QtGui import QApplication, QMainWindow, QDirModel, QColumnView

    m_model = QDirModel()

    def __init__(self):
    	QMainWindow.__init__(self)
    	self.m_fileView = QColumnView(self)
    	self.m_media = None

    	self.setCentralWidget(self.m_fileView)
    	self.m_fileView.setModel(self.m_model)
    	self.m_fileView.setFrameStyle(QFrame.NoFrame)

    	self.connect(self.m_fileView,
    		SIGNAL("updatePreviewWidget(const QModelIndex &)"), self.play)

    def play(self, index):
    	self.delayedInit()
    	self.m_media.setCurrentSource(
    		Phonon.MediaSource(self.m_model.filePath(index)))
    	self.m_media.play()

    def delayedInit(self):
    	if not self.m_media:
    		self.m_media = Phonon.MediaObject(self)
    		audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self)
    		Phonon.createPath(self.m_media, audioOutput)

def main():
    app = QApplication(sys.argv)
    QApplication.setApplicationName("Phonon Tutorial 2 (Python)")
    mw = MainWindow()
    mw.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()
