odyssey is currently the only program directly depending on ffmpeg. so my guess is, it would be the best to try and get 4.0.2 working with it. actually (afair) its only one function that acinerella is lacking, that doesnt get exposed by ffmpeg any more, and they claim it should have never been. on the other hand acinerella got updated in the mentime by morphos developer (piru), the sources are public. but it requires in turn further changes in at least one file where odyssey media player interfaces to acinerella, and according to andree, whom i asked, they aint inclined to share these changes, at least for now, because apparently it is not working as expected.
