Just a question for understanding...what's the advantage of using enum's

required (saving 4 characters by replacing '#define ' with ' ').
Documentation tools (e.g. doxy) will group them together and treat
them as a group of related properties, rather than separate entities.
That's a big one for a huge project such as FFmpeg, where in the
future many people will look at and modify your code, without
necessarily understanding everything at the beginning.
Not to mention having variables of the type "enum Whatever" instead of a
plain int, which tell immediately which kind of constants should be
assigned to it.
