Do you speak for all FFmpeg developers or only for your commits?

This is not about the headers (I am sorry if I did give this impression
at any point), but about the library that is loaded at runtime by FFmpeg.
As long as this library is closed-source, this discussion leads nowhere.
> I emailed Blackmagic to clarify this
It is not Blackmagic who does not want you to distribute FFmpeg
with their (proprietary) library, it is us who do not allow distribution
of FFmpeg binaries that link against Blackmagic libraries.
You cannot change this (we cannot either), please understand that
we should all invest our time in different issues.
