How to set 2 pass on equalizer?

[rafaleo]

About python-vlc usage:

I've just used it and it worked. But realized, that the output doesn't match with a player itself although all bands had the same frequencies. Later realized, that "2 pass" checkbox changes everything but couldn't find it within vlc.libvlc_media_player_set_equalizer sister functions.

So that's my question, how to use it?

I'd like to know that as well! ;)
