I pretty much agree with Alexis' points. To clarify... > wait for other opinions, but I'd say: libav has a cleaner codebase and > stricter development rules. (NB: some gentoo devs are member of the core > libav dev team) I'd say both projects suck hard at lack of understanding of API/ABI stability. However, if one of them is going to finally get some stability, it's rather going to be libav.

It's easiest to look at the trackers: - ffmpeg-2 [1] -- 26/26 fixed, - ffmpeg-2.4 [2] -- 3/3 fixed (but unsure if there won't be more), - libav-9 [3] -- 55/55 fixed, - libav-10 [4] -- 11/25 fixed. No offense here but in my experience, ffmpeg support in Gentoo is fixed faster than libav.
