scene filter on/off

[sonicphil]

hello,

I need to create continous screenshots from a Video.
i made that work with the Scene filter.

Problem 1: i cannot switch on an off the Scene filter without closing and restarting the vlc application.
is there a way to Switch the filiter off/on during the Video is playing?

Problem 2: Screenshots are created when the Video is paused, is it possible to Change that?

many thanks in advance!
