enums are ints (and hence signed). I doubt code assumed that they are unsigned. If code depended on these being unsigned constants, then there is no way of placing them in an enum. Are you fine with a macro, or do you prefer a static const style? Generally, it seems like FFmpeg prefers the macro method for defining such constants/flags. > > [...] > -- > Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB > > Many things microsoft did are stupid, but not doing something just because > microsoft did it is even more stupid.
