Thats not necessarily true, if its supposed to be public API, it just
has to always be present, so it would have to be changed to just do
nothing and return an error if QSV is not enabled, but the functions
still exist.
Using config.h in public headers is not something you can somehow work
around however. The public interface needs to be stable, independent
of how ffmpeg was built.
