Overview of this book

Multimedia applications are used by a range of industries to enhance the visual appeal of a product. This book will teach the reader how to perform multimedia processing using Python. This step-by-step guide gives you hands-on experience for developing exciting multimedia applications using Python. This book will help you to build applications for processing images, creating 2D animations and processing audio and video. Writing applications that work with images, videos, and other sensory effects is great. Not every application gets to make full use of audio/visual effects, but a certain amount of multimedia makes any application a lot more appealing. There are numerous multimedia libraries for which Python bindings are available. These libraries enable working with different kinds of media, such as images, audio, video, games, and so on. This book introduces the reader to the most widely used open source libraries through several exciting, real world projects. Popular multimedia frameworks and libraries such as GStreamer,Pyglet, QT Phonon, and Python Imaging library are used to develop various multimedia applications.

Preface

Chapter 8. GUI-based Media Players Using QT Phonon

The earlier chapters had focused on developing audio and video processing tools. The involvement of Graphical User Interface (GUI) was intentionally kept aside so that we could learn 'pure' multimedia-processing techniques using the GStreamer framework. However, to just 'play' an audio or a video, we would always prefer a media player with a user interface that provides an easy way to control the playback, adjust the volume, and so on.

In this chapter, we shall:

  • Develop a GUI for audio and video players using QT

  • Learn fundamental components of the Phonon framework, such as MediaObject, MediaSource, AudioOutput, and so on to build a media graph

  • Learn how to use QT Phonon framework to create media players with graphical user interface

So let's get on with it.
