I re-read the old discussion, my position has not change, about this and about any similar situations: *Filters that do the same thing as an existing filter are not welcome in libavfilter.* Rationale: the redundancy is confusing for users and for people who try to help them. Instead, two possibilities: - If the new filter is in all aspects superior to the existing filter, then it should just replace it, with the same name. - Else, the new filter can be added as an alternate mode of operation of the existing filter, with an option to switch. In any case, the working of the options should be maintained as much as possible: the new implementation should take the existing options into account (if they make sense). John, we would appreciate your input about whether these new implementation of atempo is superior or equal to the existing one with regard to your needs. Regards, -- Nicolas George
