Even if you say so... this design still doesn't make a lot of sense.
FFmpeg supports custom IO, yet it will just open new files using its
own IO behind the API user's back in some cases. FFmpeg also imposes its
own security policy about which other files can be opened, and the API
user can do almost nothing about it.

What I'm suggesting would fix all of this.
