switch deinterlace or postprocessing by runtime?

[klsc]

hy,
a have a little program with includes vlc activex.
is there a way to switch deinterlacing ore postprocessing if the vlc plays a video without stop this?
I only know that a can set global options with options (:vout-filter=deinterlace :deinterlace-mode=bob) at the time I add the file to tha playlist.

how can I switch this at runtime?
