In this chapter, we explored the capabilities of the QtMultimedia and QMultimediaWidgets modules. You learned how to play back low-latency sound effects with QSoundEffect, and how to play and record a variety of media formats using QMediaPlayer and QAudioRecorder. Finally, we created a video recording and playback application using QCamera, QMediaPlayer, and QMediaRecorder.
In the next chapter, we'll connect to the wider world by exploring Qt's networking features. We'll work with low-level networking with sockets and higher-level networking with the QNetworkAccessManager.
