QMediaService¶
- PyQt5.QtMultimedia.QMediaService
Inherits from QObject.
Description¶
The QMediaService class provides a common base class for media service implementations.
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.
