That breaks API
Its also a step away from supporting plugins.
Why plugins matter ? Because having plugin
support is a big advantage, it allows a much wider
community to work on, write and maintain filters.
With plugins, people can write filters that are
written in languages other than C. Or filters which
some developer in FFmpeg doesnt want. Or they can be
maintained externally by people who just do not like us.
Or by people who perfer a FOSS license different from
LGPL/GPL/BSD. Iam sure others can come up with more
Of course avfilter_register() isnt enough for plugins
but it or something equivalent is needed for plugins.
So i would prefer if avfilter_register() stays supported
indefinitly or in case a different system is written for
plugins then until that system is in place.
That is just a preferrance, not an objection to the patch.

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
would be bankrupt already.
