There needs to be a value to not select any track though. Whether it is 0
or -1 is a matter of convention, but we need the value. Keep in mind it's
not just about getting the description (where it is indeed useless).

That depends on the input. Some file formats provide their own plain text
subtitle description.

Many formats don't specify the language, or not in a normalized fashion
anyway. There is not much we can do.
