The doxygen you referenced documents everything, including internal
data structures.
It may be a bit unfortunate choice to have that on the website, but
its probably also used by developers of FFmpeg.

If you want to see public functions, best would be to check the
installed headers. avio.h for example doesn't export any non-public
functions (while of course avio.c contains them, which is what you
linked the doxygen of)
