another concrete thing that requires a decission on the AVClass
question (not neccessarily adding it but a clear yes or no) is the
3.1 release, we are 3 month after 3.0 so it would be time to make it

its not possible to add AVClass or AVOptions after making a 3.1 release
it can be done then only in "4.0" (assuming we match ABI major bumping
with the major version). Or maybe i should say it can be done only
with major ABI/API bump then
so the AVClass question is release blocking effectively, not sure
there are other things that block the release, probably some
regressions that should be fixed first and testing if API/ABI is
still compatible or if there are bugs that need to be fixed too

Everything should be made as simple as possible, but not simpler.
