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

Playing a video


Earlier, we saw how to play an audio. Like audio, there are different ways in which a video can be streamed. The simplest of these methods is to use the playbin plugin. Another method is to go by the basics, where we create a conventional pipeline and create and link the required pipeline elements. If we only want to play the 'video' track of a video file, then the latter technique is very similar to the one illustrated for audio playback. However, almost always, one would like to hear the audio track for the video being streamed. There is additional work involved to accomplish this. The following diagram is a representative GStreamer pipeline that shows how the data flows in case of a video playback.

In this illustration, the decodebin uses an appropriate decoder to decode the media data from the source element. Depending on the type of data (audio or video), it is then further streamed to the audio or video processing elements through the queue elements. The two queue elements...
