static PySide.phonon.Phonon.BackendCapabilities.availableVideoCaptureDevices()

Return type:

static PySide.phonon.Phonon.BackendCapabilities.isMimeTypeAvailable(mimeType)

Parameters:mimeType – unicode Return type:PySide.QtCore.bool

Often all you want to know is whether one given MIME type can be decoded by the backend. Use this method in favor of PySide.phonon.Phonon::BackendCapabilities.availableMimeTypes() as it can give you a negative answer without having a backend loaded.

Returns true if the given mimeType is supported by the backend; otherwise, returns false.

static PySide.phonon.Phonon.BackendCapabilities.notifier()

Return type:PySide.phonon.Notifier

Use this function to get a PySide.QtCore.QObject pointer to connect to the capabilitiesChanged signal.

Returns a pointer to a PySide.QtCore.QObject .

The capabilitiesChanged signal is emitted if the capabilities have changed. This can happen if the user has requested a backend change.

To connect to this signal do the following:

BackendCapabilities.notifier.capabilitiesChanged.connect(...)
