Detailed Description

Class for starting stream decoding.

This class handles starting the Decoder for the MusicPlayer via DecoderIOFactorys.

It operates on a playlist, either created with a single file, by loading a .pls or downloading it, and for each entry creates an appropriate DecoderIOFactory. The creator is simply a intermediate class that translates the next URL in the playlist to QIODevice. Ie. the DecoderIOFactoryFile just returns a QFile, whereas the DecoderIOFactoryShoutcast returns a QSocket subclass, where reads do the necessary translation of the shoutcast stream.
