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

A primer on GStreamer


In this chapter, we will be using GStreamer multimedia framework extensively. Before we move on to the topics that teach us various audio processing techniques, a primer on GStreamer is necessary.

So what is GStreamer? It is a framework on top of which one can develop multimedia applications. The rich set of libraries it provides makes it easier to develop applications with complex audio/video processing capabilities. Fundamental components of GStreamer are briefly explained in the coming sub-sections.

Comprehensive documentation is available on the GStreamer project website. GStreamer Application Development Manual is a very good starting point. In this section, we will briefly cover some of the important aspects of GStreamer. For further reading, you are recommended to visit the GStreamer project website: http://www.gstreamer.net/documentation/
