Multimedia Overview

Multimedia support in Qt is provided by the 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.


Here are some things you can do with the Qt Multimedia APIs:

  • Access raw audio devices for input and output.
  • Play low latency sound effects.
  • Play 3D spatial audio.
  • Play media files in playlists (such as compressed audio or video files).
  • Record audio and compress it.
  • Use a camera, including viewfinder, image capture, and movie recording
  • Decode audio media files into memory for processing.

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 recipes.

For some quick recipes, see this table:


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 Supported Media Formats for more detail.

Changes from Previous Versions

If you previously used Qt Multimedia in Qt 5, see Changes to Qt Multimedia for more information on what has changed, and what you might need to change when porting code to Qt 6.
