This isn't about libvlc control but about the video output core. "video
filter" filters (v1) are exactly like fake vouts. Which means that
adding or removing one triggers a rebuild of the vout. (As opposed to
"video filter2" or "subpicture filter" which can be added/removed

So the question here boils down to:
What logic do we apply to keep the vout *and* enforce item specific
:vout-filter= options at the same time?
(Basically :vout-filter= changes should trigger a respawn and keep track
of the deinterlace settings)

(Or to sum it up: The who filters handling code is a total mess in
