The -\l {changed features} section highlights changes relevant to porting. - -Also, note that widget-based classes, such as \l QVideoWidget, are now in a separate -module called Qt Multimedia Widgets. - -\section1 New features in Qt 5.0 - -There are a number of new features in Qt Multimedia: -\list -\li Expanded QML API -\li In addition to the \l Video QML type, there is now the option of using \l MediaPlayer and \l VideoOutput together -\li QML \l Torch class -\li New \l QAudioRecorder class -\li Volume support for QAudioOutput and QAudioInput -\li More examples and documentation -\li QSound moved from Qt GUI to Qt Multimedia -\li QSoundEffect available to C++ now, as well as QML -\li Various other API improvements and bugfixes -\endlist - - -\section1 Removed features - -A number of classes or features previously offered in Qt Multimedia or Qt Multimedia Kit have -been removed. - -\table 70% - \header - \li Removed feature - \li Notes - \row - \li QMediaImageViewer - \li This class (and related controls and services) were removed since - their functionality was not suitable for many applications -\endtable - -\section1 Changed features - -A number of classes previously offered in Qt Multimedia or Qt Multimedia Kit have -changed in ways that may affect previously written code. This table highlights such changes. - -\table 70% - \header - \li Changed feature - \li Notes - \row - \li \c qmake project file changes - \li Previously, to use Qt Multimedia Kit, the \c qmake project file must contain - \code - CONFIG += mobility - MOBILITY += multimedia - \endcode - Now, you only need to write - \code - QT += multimedia - \endcode - Or, if you want to use the widget classes, - \code - QT += multimedia multimediawidgets - \endcode - \row - \li Namespaces - \li The \c QtMultimediaKit namespace has been renamed to QMultimedia. This - affects a few enumerations, namely \c SupportEstimate, \c EncodingQuality, - \c EncodingMode and \c AvailabilityStatus. Searching and replacing - \c QtMultimediaKit with \c QMultimedia will greatly aid porting efforts. Metadata - have been split off into their own namespace, QMediaMetaData. - \row - \li Metadata types - \li In Qt Multimedia Kit, pre-defined metadata keys were enumerations in the - \c QtMultimediaKit namespace. These pre-defined keys have been changed to - string literals in the \c QMediaMetaData namespace, for consistency with - extended keys. - \row - \li Metadata accessor methods - \li In Qt Multimedia Kit, there were two different families of methods to access - metadata. Functions such as \c QMediaObject::metaData() operated on pre-defined - metadata using enumerated keys, while functions such as - \c QMediaObject::extendedMetaData() operated on extended metadata using - string keys. Qt 5 combines both families into one (e.g. QMediaObject::metaData()), - which can operate on both pre-defined and extended metadata, using string keys. - \row - \li Qt Metatype registration - \li Qt 5 registers many more classes and types with the meta-object system than before. - If you have previously applied Q_DECLARE_METATYPE macros to any Qt Multimedia class, - you will probably need to remove them. - \row - \li QSoundEffect availability - \li The SoundEffect QML type was publicly accessible in Qt Multimeda Kit, - and now the C++ version is officially public too. If your code contains the - previously undocumented QSoundEffect, you may need to update it. - \row - \li Camera controls - \li A large number of the camera controls (QCameraImageProcessingControl, - QCameraFocusControl, etc.) have been updated to address a number of - design flaws. In particular, a number of discrete - accessor methods have been collapsed into parametrized methods, and - the ranges or data types of some parameters have been adjusted. - -\endtable - -*/ |
