How can I...?

Example 12 : Simple TCP based streamer that repeatedly streams (3 times) the same audio file. The reason it's the same file is because it's configured with a playlist that is created: [ shortfile, shortfile, shortfile ]. If this was [ song_one, song_two, song_three ], then this would be a simple streamer that had a playlist of 3 songs played repeatedly. Something that does this is often referred to as a carousel. Components used: SimpleServer, JoinChooserToCarousel, FixedRateControlledReusableFileReader, ForwardIteratingChooser, pipeline

    from Kamaelia.Chassis.Prefab import JoinChooserToCarousel

    from Kamaelia.Util.Graphline import Graphline
    from Kamaelia.Util.Chooser import ForwardIteratingChooser

    shortfile = "/opt/kde3/share/sounds/KDE_Startup_2.ogg"

    FILES_TO_STREAM = [ shortfile, shortfile, shortfile ]# [ file_to_stream, file_to_stream2 ]
    BITRATE = 800000 # 38000
    SERVERPORT = 1500

    return protocolFactory

    if __name__ == '__main__':

    server = SimpleServer( protocol = filereader, port = SERVERPORT ).run()
