the question is, why is libav using unbuffered I/O, and does moving to fopen make sense?
Because libav already has got a buffering layer of its own, AVIOContext, which provides buffering on top of whichever unbuffered API is used below (file descriptors, sockets, etc). If this buffering doesn't work properly for your case, you're probably hitting some corner case in it where the buffering doesn't help as much as it should (or the input file is structured in a way that forces the IO layer to seek a lot).
Instead of adding buffering at yet another layer it would make more sense to try to figure out why the existing buffering doesn't help in your particular case, and if there's something that can be done about it.
