def set_equalizer(self, p_equalizer):
        '''Apply new equalizer settings to a media player.
        The equalizer is first created by invoking L{audio_equalizer_new}() or
        L{audio_equalizer_new_from_preset}().
        It is possible to apply new equalizer settings to a media player whether the media
        player is currently playing media or not.
        Invoking this method will immediately apply the new equalizer settings to the audio
        output of the currently playing media if there is any.
        If there is no currently playing media, the new equalizer settings will be applied
        later if and when new media is played.
        Equalizer settings will automatically be applied to subsequently played media.
        To disable the equalizer for a media player invoke this method passing None for the
        p_equalizer parameter.
        The media player does not keep a reference to the supplied equalizer so it is safe
        for an application to release the equalizer reference any time after this method
        returns.
        @param p_equalizer: opaque equalizer handle, or None to disable the equalizer for this media player.
        @return: zero on success, -1 on error.
        @version: LibVLC 2.2.0 or later.
