Multimedia support in Qt is provided by the \l{Qt Multimedia} module. The Qt Multimedia module provides a rich feature set that enables you to easily take advantage of a platform's multimedia capabilities such as media playback and the use of camera and radio devices. \section1 Features Here are some examples of what can be done with Qt Multimedia APIs: \list \li Access raw audio devices for input and output \li Play low latency sound effects \li Play media files in playlists (such as compressed audio or video files) \li Record audio and compress it \li Tune and listen to radio stations \li Use a camera, including viewfinder, image capture, and movie recording \li Play 3D positional audio with \l{Qt Audio Engine QML Types}{Qt Audio Engine} \li Decode audio media files into memory for processing \li Accessing video frames or audio buffers as they are played or recorded \endlist \section1 Multimedia Components Qt's multimedia APIs are categorized into four main components. More information (including background information and class references) is available here: \list \li \l {Audio Overview} \li \l {Video Overview} \li \l {Camera Overview} \li \l {Radio Overview} \endlist \section1 Multimedia Recipes For some quick recipes, look at the overviews above and consult this table: \table 70% \header \li Use case \li Examples \li QML Types \li C++ Classes \row \li Playing a sound effect \li \li \li QSoundEffect \row \li Playing low latency audio \li \l{Audio Input Example}{audioinput}, \l{Spectrum Example}{spectrum} \li \li QAudioOutput \row \li Playing encoded audio (MP3, AAC etc) \li \l{Media Player Example}{player} \li \l Audio, \l {MediaPlayer} \li QMediaPlayer \row \li Accessing raw audio input data \li \l{Spectrum Example}{spectrum}, \l{Audio Input Example}{audioinput} \li \li QAudioInput \row \li Recording encoded audio data \li \l{Audio Recorder Example}{audiorecorder} \li \li QAudioRecorder \row \li Discovering raw audio devices \li \l{Audio Devices Example}{audiodevices} \li \li QAudioDeviceInfo \row \li Video Playback \li \l{Media Player Example}{player}, \l{QML Video Example}{qmlvideo}, \l{QML Video Shader Effects Example}{qmlvideofx} \li \l MediaPlayer, \l VideoOutput, \l Video \li QMediaPlayer, QVideoWidget, QGraphicsVideoItem \row \li Video Processing \li \l {QML Video Example}{qmlvideofx} \li \l {MediaPlayer}, \l VideoOutput \li QMediaPlayer, QAbstractVideoSurface, QVideoFrame \row \li Listening to the radio \li \l {Declarative Radio Example}{declarative-radio} \li \l Radio, \l RadioData \li QRadioTuner, QRadioData \row \li Accessing camera viewfinder \li \l {Camera Example}{camera}, \l {QML Camera Example}{declarative-camera} \li \l Camera, \l VideoOutput \li QCamera, QVideoWidget, QGraphicsVideoItem \row \li Viewfinder processing \li \li \l Camera, \l VideoOutput \li QCamera, QAbstractVideoSurface, QVideoFrame \row \li Capturing photos \li \l {Camera Example}{camera}, \l {QML Camera Example}{declarative-camera} \li \l Camera \li QCamera, QCameraImageCapture \row \li Capturing movies \li \l {Camera Example}{camera}, \l {QML Camera Example}{declarative-camera} \li \l Camera \li QCamera, QMediaRecorder \row \li 3D sound sources \li \li \l {AudioEngine Example}{Audio Engine} \li \l {AudioEngine}, \l Sound \li \endtable \section1 Limitations The Qt Multimedia APIs build upon the multimedia framework of the underlying platform. This can mean that support for various codecs or containers can vary between machines, depending on what the end user has installed. \section1 Advanced Usage For developers wishing to access some platform specific settings, or to port the Qt Multimedia APIs to a new platform or technology, see \l{Multimedia Backend Development}. \section1 Changes from Previous Versions If you previously used Qt Multimedia in Qt 4, or used Qt Multimedia Kit in Qt Mobility, please see \l {Changes in Qt Multimedia} for more information on what changed, and what you might need to change when porting code. \section1 Reference Documentation \section2 QML Types The QML types are accessed by using: \code import QtMultimedia 5.6 \endcode \annotatedlist multimedia_qml The following types are accessed by using \l{Qt Audio Engine QML Types}{Qt Audio Engine}: \code import QtAudioEngine 1.1 \endcode \annotatedlist multimedia_audioengine \section2 Multimedia Classes \annotatedlist multimedia */
