Dear List,
The app i wrote using Phonon of Qt 4.8.2 works fine for playback when i compile with PyQt4 4.9.1+sip 4.13.2+QScintilla 2.6.1. But failed after i upgrade to PyQt 4.9.3+Sip 4.13.3+QScintilla 2.6.2. (Recompiled one by one.) After i ask it to play, nothing just happen, except two WARNING got printed in the terminal: ========================== WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded ========================== OS: Mac OS X Lion 10.7.4 Python: 2.7.3 And every time i launch my app, In the terminal it reports: ========================== 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 WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::AudioOutput ( no objectName ). ========================== The app works fine before upgrade. So any advice?
