You can already read from an URL, just pass one into osgmovie and watch it :-)

This is the bit which is unknown to me right now. I've see a couple
of online tutorials on using ffmpeg to pull in live video streams and
have used it successfully to create an movie file from my webcam,
but... I don't know how to wire it up yet. I haven't spotted any
explanation of this feature at the API level yet.

Quicktime has it's own peculiar live video setup, which has lots of
its own caveats and issues. Hopefully we wont' have to jump through
so many hoops to get the ffmpeg plugin to read from live source.

Yep, pinging the list for those who are already a bit more experience
with ffmpeg would make sense.

No better coding motivation than actually needing the results :-)
Might I suggest you have a look at taking apart the ffmpeg application
code to spot how it reads from webcam.
Here's one of the tutorials I came across, perhaps the command line
options used will provide some clues.
