In the first project, we learned the fundamentals of the QT Phonon framework. In this project, we will extend that knowledge further by developing a video player. The Audio player was developed by building a media graph. Various nodes such as MediaObject, AudioOutput, and Effects were linked together by creating a Phonon.Path. If the goal is just to develop a simple audio or video player, the job is even simpler. Phonon has a module VideoPlayer that provides an abstract way to play an audio or a video without the need to explicitly create MediaObject, AudioOutput, and some other objects. All it needs is a MediaSource. It is also possible to create a custom media graph by adding various audio-effect nodes. We will see how to do it later. For now, let's write a simple video player application using QT Phonon. The following illustration shows the video player in action.
