Detailed Description

Media services provide implementations of the functionality promised by media objects, and allow multiple providers to implement a QMediaObject .

To provide the functionality of a QMediaObject media services implement QMediaControl interfaces. Services typically implement one core media control which provides the core feature of a media object, and some number of additional controls which provide either optional features of the media object, or features of a secondary media object or peripheral object.

A pointer to media service’s QMediaControl implementation can be obtained by passing the control’s interface name to the requestControl() function.

QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
        mediaService->requestControl("org.qt-project.qt.mediaplayercontrol/5.0"));

Media objects can use services loaded dynamically from plug-ins or implemented statically within an applications. Plug-in based services should also implement the QMediaServiceProviderPlugin interface. Static services should implement the QMediaServiceProvider interface. In general, implementing a QMediaService is outside of the scope of this documentation and support on the relevant mailing lists or IRC channels should be sought.

class PySide2.QtMultimedia.QMediaService(parent)
param parent

PySide2.QtCore.QObject

Construct a media service with the given parent . This class is meant as a base class for Multimedia services so this constructor is protected.

PySide2.QtMultimedia.QMediaService.releaseControl(control)
Parameters

controlPySide2.QtMultimedia.QMediaControl

Releases a control back to the service.

PySide2.QtMultimedia.QMediaService.requestControl(name)
Parameters

name – str

Return type

PySide2.QtMultimedia.QMediaControl

Returns a pointer to the media control implementing interface .

If the service does not implement the control, or if it is unavailable a null pointer is returned instead.

Controls must be returned to the service when no longer needed using the releaseControl() function.
