players:  different players. The players use a C++ base plugin system
          for input/output and decoders.
          I think its a very powerful system. 

yaf:      The streaming library. Includes yaf-protocol wrappers (for the
          players) and useful frontend classes. Much more stuff
          than the players directory. If you like to know how
          it works look in the 7 examples in the kmpg package.
