After bugging my eyes out over this and wondering about UNIX and POSIX and Windows namespaces and escape notations . It is a stray i before filtercomplex that ' s throwing the whole thing off ! I wasted four hours on this problem today , including trying to find a workaround with VLC , only to discover all by myself that I am an idiot . Thank you all ! <| sep |> Same every game .

If it ' s not flat then it may just be a superficial mark . However your picture , particularly the middle one , looks like a definitive change in exterior diameter there .
