I've wasn't aware of this but playing with the "Video Mixer" example
(the simple one that is just a NIB and a QC comp) I've just realised
I can render a QC composition once but send different portions of it
to different output windows.
Use one QC View and then create multiple NSImageView boxes linked to
published image output
ports of the composition.
Forgive me if this is obvious to people, I was under the illusion
that a QC comp could only render to one window so this is a bit of a
revelation to me.
This is brilliant.... without a line of code I can render the
portion of my VJ mixer without the interface elements in a second
floating display then drag it to the TV out. with a bit of clever
window placement I can even get full screen with no title bar....
I'll have an example that people can download soon.
can someone confirm that this is only rendering the QC comp once so
it won't have a huge overhead right?
I'm also trying to make sense of the Performer example hoping to
reuse the NSMediaSource drop box portion of it. Why does Performer
use a custom NSView instead of a QCView? just trying to understand
the architecture and how it is put together?
Also, can I some how "back bind" an NSSlider to midi control inside a
composition so the slider updates on the screen
when I move the midi controller? How would you do this?
