Applications that need to play sounds or show videos are usually games, while others are full-blown multimedia apps. Qt Multimedia can handle both.
Qt Multimedia can be used with both Qt Widgets and Qt Quick, or even without a GUI interface. It has both C++ and QML APIs, but the QML API has a few special treats and tricks. A little-known fact is that Qt can also play 3D positional audio in Qt Quick. You can control the gain and pitch with three dimensions.
We will cover the following topics in this chapter:
- Sonic vibrations – audio
- Image sensors – camera
- Visual media – playing video
- Tuning it in – FM radio tuner
