C# 클래스 wpf_player.ObservableStream

This class extends memory stream to allow waiting state management and position change notify. Using the WaitForMore method, a event will be launched when the needed data has been read. Position Changed event will be launched when more data has been written on the stream: the maximum resolution for this events is 1024 byte; if the position changed for less than 1024 byte the event won't be raised.
