Detailed Description
If a QMediaService can provide write access to the meta-data of its current media it will implement QMetaDataWriterControl. This control provides functions for both retrieving and setting meta-data values. Meta-data may be addressed by the keys defined in the QMediaMetaData namespace.
The functionality provided by this control is exposed to application code by the meta-data members of QMediaObject, and so meta-data access is potentially available in any of the media object classes. Any media service may implement QMetaDataControl.
The interface name of QMetaDataWriterControl is org.qt-project.qt.metadatawritercontrol/5.0 as defined in QMetaDataWriterControl_iid.
See also QMediaService::requestControl() and QMediaObject.
