How can I...?

Example 2: A Simple TCP Based Server that allows multiple connections at once, but sends a random ogg vorbis file to the client. Includes a simple TCP based client for this server, that connects to the server, decodes the ogg vorbis audio and plays it back. Components used: pipeline, SimpleServer, ReadFileAdaptor, TCPClient, VorbisDecode, AOAudioPlaybackAdaptor

    #!/usr/bin/python

    from Kamaelia.Util.PipelineComponent import pipeline
    from Kamaelia.SimpleServerComponent import SimpleServer
    from Kamaelia.Internet.TCPClient import TCPClient
    from Kamaelia.vorbisDecodeComponent import VorbisDecode, AOAudioPlaybackAdaptor
    import Kamaelia.ReadFileAdaptor

    file_to_stream = "/usr/share/wesnoth/music/wesnoth-1.ogg"
    clientServerTestPort=1500

    def AdHocFileProtocolHandler(filename):
    class klass(Kamaelia.ReadFileAdaptor.ReadFileAdaptor):
    def __init__(self,*argv,**argd):
    super(klass,self).__init__(filename, readmode="bitrate", bitrate=400000)
    return klass

    server=SimpleServer(protocol=AdHocFileProtocolHandler(file_to_stream),
    port=clientServerTestPort).activate()

    pipeline(
    TCPClient("127.0.0.1",clientServerTestPort),
    VorbisDecode(),
    AOAudioPlaybackAdaptor()
    ).run()
