FFmpeg filters: libavfilter

[Illico]

Zip,
When you configure your FFmpeg build, do you enable any of the existing filters : libavfilter ?
http://ffmpeg.org/libavfilter.html

--enable-avfilter
--enable-filter=movie
--enable-avfilter-lavf

Some of them could be interesting, for example:
CROP
CROPDETECT
SCALE
OVERLAY

No I do not. You can see the configure command when you execute FFmpeg.

I'm sure they would be interesting, not sure though about the Linux users, they would not have the same functionality.
