Then the best solution - imo! - is that you send a patch that adds your
new filter that uses the existing asm optimizations if FFmpeg was
configured for GPL.
First send one patch only adding a new filter (with a new name) to
get some technical review
One possible procedure for a change that can actually be committed
is that you send two patches:
One that removes the existing filter (but not the asm code) and one
that adds your new filter.
