This is intentional, the function is meant for internal use in libavformat,
not for use outside of the library.
Change the name of the function so that it starts with "av_" if you want
it exported but remember that you have to do this for every new version
of FFmpeg and note that we may change (or remove) the function
(An alternative is to edit libavformat/libavformat.v)
