IIRC, VDPAU is not the only place that checks for pkg-config version
numbers.

This bug needs FFmpeg people to face the reality that they have set their
project as a downstream of the unspeakable libav. Thus they must not
override upstream version numbers, but instead add their own separate ones.
Everybody else works that way, and pkg-config is designed with that
assumption.
