|
\brief The QMetaDataWriterControl class provides write access to the
|
|
meta-data of a QMediaService's media.
|
|
|
|
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
|
|
QtMultimedia::MetaData 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 \c org.qt-project.qt.metadatawritercontrol/5.0 as
|
|
defined in QMetaDataWriterControl_iid.
