Hi all,
Again, thanks very much for the time spent answering my questions!

Mmm. Actually I'm new to Final Cut and related software so I'm not
sure what is 'common' to do in my case.
To refrain: I have a device that offers a SDI stream to MacOS through
my driver (by means of an IOUserClient). Now I'd like users to be able
to comfortably capture this stream into Final Cut and related.
Black Magic Design builds comparable products and also offers a plugin
for Final Cut Pro HD. A look at the usage manual (page 20) suggests
they've built a plugin for Final Cut that makes it possible to
realtime capture streams from their devices:
http://www.blackmagic-design.com/downloads/manuals/decklinkmacmanual.pdf
So it's possible and it's being used. Although, it seems they did not
use a 'normal' FxPlug plugin; as capturing has to be started using
"Log & Capture" from the file menu rather than selecting a plugin to
capture the stream.
I'm not really sure what to do here, using the FxPlug framework to
build a capture source in Final Cut seems to be a strange idea. As far
as I have seen, the FxGenerator FxPlug plugin is build to return one
frame at a time, so it seems not to be the ideal solution to import 25
frames/sec.
As opposed to building a capture source for use within Final Cut,
would it make more sense to build a QuickTime plugin for my purpose?
Thanks in advance!
Greetings,
Kris
