Analysis

Overview

The media engine is responsible for rendering audio and video. Write a module that implements the video and audio interfaces found in org.sophie2.main.media.fobs.

Audio should play regardless of whether it is being used by a scene or not. Video does not render directly to the screen, rather the grabFrame interface returns the image which will be rendered by the scene.

It seems as if JMF is a good place to start for implementing the engine. Start by looking at:

​http://java.sun.com/javase/technologies/desktop/media/jmf/reference/faqs/index.html#what

You will also create an extension point that wraps the class and provides a mechanism for the scene to get the audio or video handler.

Task requirements

• Write a module for media playback
• Start with JMF
• Expose an extension point for access to the handlers
• Implement the Interface found in org.sophie2.main.media.fobs

Task result

The result of this task is a module

Implementation idea

• Note that JML can only do mp3 on windows, so we need to figure out what to do about this because supporting mp3 is important

Is this task about rendering media, such as video and audio? How should it work with scenes and content objects?

Publish extension for playing video handler and audio handler

org.sophie2.main.media.fobs is the interface for the engine

audio should play even if grab frames is not called

wrap jmf class in an extension and publish it
