There are a few legacy bits left in place so it passes CI, and then qt5.git etc can be updated. Change-Id: I6b082e50e6958c72fdabc2974992e16d90dafa3a Reviewed-on: http://codereview.qt-project.org/5368 Reviewed-by: Qt Sanity Bot <qt_sanity_bot@ovi.com> Reviewed-by: Jonas Rabbe <jonas.rabbe@nokia.com>

\brief The 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
|
||||
QtMultimedia::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
|
||||
\c com.nokia.Qt.QMetaDataReaderControl/1.0 as defined in
|
||||
QMetaDataReaderControl_iid.

||||
