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.

Summary


We learned fundamentals of GStreamer API in previous chapters on audio processing.

In this chapter we moved one step further to develop some useful video processing utilities using Python and GStreamer. To accomplish this task, we learned about several new GStreamer plugins required for processing videos.

Specifically, we covered:

  • Pipeline that handles audio and video: We learned how to build a GStreamer pipeline that can handle both audio and video tracks from the input video file. This was used to 'play' a video file and it was also the basic pipeline used in several video-processing tools developed in this chapter.

  • Separating audio/video: With the help of example, we learned how to save an audio/video track of a video file into two different files.

  • Mixing audio/video: We wrote a program that can mix an audio and video stream into a single video file.

  • Video effects: How to adjust the properties such as brightness, contrast, and saturation for a streaming video.

  • Text overlay: We developed...
