This module provides a MediaControl object, which implements an API
inspired from the OMG Audio/Video Stream 1.0 specification. Moreover,
the module provides a Object type, which gives a low-level access to
the vlc objects and their variables.

Documentation can be found on the VLC wiki : 
http://wiki.videolan.org/index.php/PythonBinding

Example session:

import vlc
mc=vlc.MediaControl(['--verbose', '1'])
mc.playlist_add_item('movie.mpg')

# Start the movie at 2000ms
p=vlc.Position()
p.origin=vlc.RelativePosition
p.key=vlc.MediaTime
p.value=2000
mc.start(p)
# which could be abbreviated as
# mc.start(2000)
# for the default conversion from int is to make a RelativePosition in MediaTime

# Display some text during 2000ms
mc.display_text('Some useless information', 0, 2000)

# Pause the video
mc.pause(0)

# Get status information
mc.get_stream_information()

# Access lowlevel objets
o=vlc.Object(1)
o.info()
i=o.find_object('input')
i.list()
i.get('time')
