It was my expectation that it would only make sense to use a set of
dynamic libraries generated from the same build (and thus revision),
not to mix and match. Is there a cost to no longer allowing (i.e.
documenting) mixing of library versions? Is there a benefit, e.g. in
being able to break (internal) ABI (not an issue i oversee)?

(My interest here of course is moving forward with avdevice and
implementing their APIs in dshow.)
