Video out, not just video in (Read 985 times)

Video out, not just video in

So, the Video library has a nice set of options for getting video in from various sources. What about piping the contents of a Processing window (or a PImage -- whatever) OUT to various outputs (composite video, etc.)?

Specifically I'm thinking of a Blackmagic card, which goes through the usual Quicktime interface & is easy to pull up as a source. I'm just looking to go the other way.

(And not just by setting the output to act as an extension of the desktop, like an external monitor, and dragging the Processing window into position -- I'm hoping for something a little more programmatic & direct.)

Any clues?

Thanks so much.

So just a bit of, er, self-follow-up here -- I suspect if there's not some feature built in to Processing that I'm just dumbly overlooking (and I don't think there is) then the solution must reside somewhere in here --

Does anybody have any experience with video out and Quicktime in general and/or QT for Java?

2-3 years ago i tried to implement a movieplayer using qtj that would allow to have processing sketches run as a video layer (mixed with other sources). it was working to a certain level, but i could not get rid of the flickering (maybe a threading issue). i'm not too sure where my code ended up, but i can search for it over the weekend and mail it to you.

That would be terrific, if you can dig it up. Thanks!

BTW, I totally figured this out. Has to do with diving a little deeper into Java and using the AWT libraries to select different displays. This is for the benefit of anyone who finds this thread via googling.
