Both ffmpeg.c and the API are very complex, so it's obvious that
ffmpeg.c can't possibly be using all possible ways the API can be used.

If you really want a concrete example: av_seek_frame() is not used in
any of the command line tools. Except ffserver.c, which is AFAIK not
involved in any tests, and libavfilter/src_movie.c, which probably
could be used in a FATE test, but passes a static set of flags and
can't e.g. execute multiple seeks with multiple target destinations,
and would make a very bad test.

(Why do I even have to explain this.)
