What order are vop filters processed in?
It seems to me that crop and scale are processed from back to front,
i.e.
-vop crop=x:y:z:t,scale=a:b
the scaling will be done first and cropping second, whereas
-vop scale=a:b,crop=z:y:z:t
the cropping is done before the scaling.
If that is the case, wouldn't it make more sense to apply the de-noise
and de-interlace filters before the scaling, e.g.
-vop scale=a:b,crop=z:y:z:t,pp=tn/lb
or even
-vop scale=a:b,pp=tn/lb,crop=z:y:z:t
instead of at the end of the filter process, as shown in the docs?
Or am I missing something?
