Question

我正在尝试在mac上使用带有pyside的声子。我希望能够在带有pyside的桌面应用程序中在小部件中播放快速电影。

我通过macports从源代码安装了phonon，qt和pyside

$ sudo port -s -v install phonon qt4-mac
$ sudo port -s -v install py27-pyside

我可以按照以下方式确认安装

$ port installed phonon qt4-mac
The following ports are currently installed:
  phonon @4.6.0_1 (active)
  qt4-mac @4.8.5_0 (active)

我发现了一些简单的代码来测试它..

import sys
from PySide import QtCore, QtGui
from PySide.phonon import Phonon

app = QtGui.QApplication(sys.argv)
testPlayer = Phonon.VideoPlayer()
testMedia = Phonon.MediaSource('/path/to/media/test_MOV.MOV')
testPlayer.load(testMedia)
testPlayer.play()
testPlayer.show()

sys.exit(app.exec_())

然而，在pycharm中运行代码时会出现以下错误。

Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!
WARNING: Phonon needs QCoreApplication::applicationName to be set to export audio output names through the DBUS interface 
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded

WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded

看起来后端工作不正常，而且声音没有连接到quicktime？如果是这种情况，我能解决这个问题吗？我该如何设置插件路径？ - 我找不到osx的信息。

或者另外还有另一种更好的方法可以在pyside中播放音频而不是声音吗？

提前感谢。

运行以下命令，似乎列出了这些命令，但未加载

sudo launchctl load -w /Library/LaunchDaemons/org.freedesktop.dbus-system.plist
sudo launchctl load -w /Library/LaunchAgents/org.freedesktop.dbus-session.plist

如何在mac osx pyside上安装带macports的声子
