Description:

def libvlc_video_set_key_input(p_mi, on):
    '''Enable or disable key press events handling, according to the LibVLC hotkeys
    configuration. By default and for historical reasons, keyboard events are
    handled by the LibVLC video widget.
    @note: On X11, there can be only one subscriber for key press and mouse
    click events per window. If your application has subscribed to those events
    for the X window ID of the video widget, then LibVLC will not be able to
    handle key presses and mouse clicks in any case.
    @warning: This function is only implemented for X11 and Win32 at the moment.
    @param p_mi: the media player.
    @param on: true to handle key press events, false to ignore them.
