Detailed DescriptionThe QMetaDataReaderControl class provides read access to the meta-data of a QMediaService's media. If a QMediaService can provide read or write access to the meta-data of its current media it will implement QMetaDataReaderControl. This control provides functions for both retrieving and setting meta-data values. Meta-data may be addressed by the well defined keys in the QtMultimediaKit::MetaData enumeration using the metaData() functions, or by string keys using the extendedMetaData() functions. 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 QMetaDataReaderControl. The interface name of QMetaDataReaderControl is com.nokia.Qt.QMetaDataReaderControl/1.0 as defined in QMetaDataReaderControl_iid. See also QMediaService::requestControl() and QMediaObject. Member Function Documentation
