Examples of MediaReader

com.xuggle.mediatool.MediaReader
Opens a media container, and decodes all audio and video in the container.
The MediaReader class is a simplified interface to the Xuggler library that opens up an {@link IContainer} object, and then everytime you call {@link MediaReader#readPacket()}, attempts to decode the packet and call any registered {@link IMediaListener} objects forthat packet.
The idea is to abstract away the more intricate details of the Xuggler API, and let you concentrate on what you want -- the decoded data.
