\title Multimedia Overview
\brief A set of APIs for working with audio, video and camera devices.
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 devices.
\section1 Features
Here are some things you can do with the 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 Use a camera, including viewfinder, image capture, and movie recording
\li Decode audio media files into memory for processing.
\endlist
\section1 Multimedia Components
The Qt Multimedia APIs are categorized into three main components. More
information specific to each component is available in the overview pages. You
can also take a look at some \l{Multimedia Recipes}{recipes}.
\list
\li \l {Audio Overview}
\li \l {Video Overview}
\li \l {Camera Overview}

\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 will vary
between machines. This support depends on what the end user has installed.
See \l{Supported Media Formats} for more detail.
\section1 Changes from Previous Versions
If you previously used Qt Multimedia in Qt 5, see
\l{Changes to Qt Multimedia} for more information on what has changed, and what
you might need to change when porting code to Qt 6.
\section1 Reference Documentation
\section2 QML Types
The QML types are accessed by using:
