NAME

       pykaraoke - free CDG/MIDI/MPEG karaoke player

SYNOPSIS

       pympg mpegfilename.mpg

OVERVIEW

       pykaraoke is a free karaoke player for Linux, FreeBSD and Windows.

       pymng  is  an  MPEG  player built using python. It was written for the PyKaraoke project but is in fact a
       general purpose MPEG player that could be used in other python projects requiring an MPEG player.

       The player uses the pygame library (www.pygame.org), and can therefore run on any operating  system  that
       runs pygame (currently Linux, FreeBSD, Windows and OSX).

       You  can use this file as a standalone player, or together with PyKaraoke. PyKaraoke provides a graphical
       user interface, playlists, searchable song database etc.

       For those writing a media player or similar project who would like MPG  support,  this  module  has  been
       designed to be easily incorporated into such projects and is released under the LGPL.

USAGE

       To start the player, pass the MPEG filename/path on the command line:

            python pympg.py /path/song.mpg

       You  can also incorporate a MPG player in your own projects by importing this module. The class mpgPlayer
       is exported by the module. You can import and start it as follows:

            import pympg
            player = pympg.mpgPlayer("/path/song.mpg")
            player.Play()

       If you do this, you must also arrange to call pympg.manager.Poll() from time to time, at least every  100
       milliseconds or so, to allow the player to do its work.

       The class also exports Close(), Pause(), Rewind(), GetPos().

       There are two optional parameters to the initialiser, errorNotifyCallback and doneCallback:

       errorNotifyCallback,  if  provided,  will  be  used  to  print out any error messages (e.g. song file not
       found). This allows the module to fit together well with GUI playlist  managers  by  utilising  the  same
       GUI's  error  popup  window  mechanism  (or  similar).  If no callback is provided, errors are printed to
       stdout. errorNotifyCallback should take one parameter, the error string, e.g.:

            def errorPopup (ErrorString):
                 msgBox (ErrorString)

       doneCallback can be used to register a callback so that the player  calls  you  back  when  the  song  is
       finished playing. The callback should take no parameters, e.g.:

            def songFinishedCallback():
                 msgBox ("Song is finished")

       To register callbacks, pass the functions in to the initialiser:

            mpgPlayer ("/path/song.mpg", errorPopup, songFinishedCallback)

       These parameters are optional and default to None.

       If the initialiser fails (e.g. the song file is not present), __init__ raises an exception.
