That is true, but it comes with an additional function (or macro). The
relative costs of an additional argument or an additional function depends
on your knowledge of the API.

You are very much familiar with ffmpeg API, so you know the various
functions, and the few more keystrokes are what bother you.

But think of a proficient C programmer who is only vaguely familiar with
ffmpeg's API: the exact meaning of foo_seek(..., SEEK_CUR) will be obvious
to him, since he already knows (f)seek(..., SEEK_CUR). On the other hand,
he will guess mostly what foo_skip(...) does based on the name, but not the
specifics (return value, particular cases, etc.).

Whether the API should favor generic C hackers or ffmpeg hackers is open to
discussion, and I have no advice on the subject.

Nothing to add here.
