why would you want to use linux?
now that question is stupid but so is yours.
You have posted a list of shortcommings of libavfilter and we would
like to improve things, adding the ability to load *synth filters
to libavfilter removes a large part of the problems you listed.
I understand that you prefer that libavfilter is removed and replaced
by vapoursynth but vapoursynth is not a replacement for it, it lacks
quiet a few things currently and we do not know if it ever will be a
So please lets try to move forward and improve, if you want to add
a filter framework as a demuxer,
sure go ahead. It certainly will have its users.
But libavfilter also has its users and at least i would like to
have the ability to use *synth filters, *synth scripts and all that
from it. if you want to implement that for us, it certainly would
make me happy and i think other people who work on libavfilter too.
You know vapoursynth so you are quite qualified to do it, but if you
dont want to, someone else should.

Frequently ignored awnser#1 FFmpeg bugs should be sent to our bugtracker. User
