however, i would very much prefer to have *native* plugins available
as well (e.g. using AV-kit) - simply because it is what most people
will expect.
Yes. AVFoundation is what you'll have to use at this point.
Must it be written in C++ or can it be written in objective C?
ObjectiveC++ is the way to go.
(you need C++ to make Gem recognize the plugin; you can use ObjC to
properly interact with the AVFoundation Framework)
but who is going to implement it?
I've started on it by wrapping the AVFoundation Player and Grabber classes from OpenFrameworks, but I haven't been able to put much time into it since a few months ago. It's kind of low on my list right now ...
