Yep, that did it. Works perfectly. And for the curious ones out there I did some tests.
I did a test (during work as a web developer, so with Photoshop, Coda, Mail, iTunes and Safari running and in use while driving a 1920×1200 display (not outputting the video on that BTW)) on my Macbook Air with the following setup:
– Virtual DJ running with 2 movie clips (crossfader in the middle, so both were visible at probably 50% each)
– The clips where looped (which seems to take a heavier load on the CPU)
– The Syphon Server plugin activated
– MadMapper running and displaying the visuals from Virtual DJ on 11 surfaces (9 quads and 2 circles)
– The machine is the 2011 Macbook Air 13″ core i7 1.8Ghz and 4GB RAM
I’m running this setup for over an hour now, without any problem!
Avarage CPU load is around 55% but sometimes peaks to 75% (presumably when the long loop restarts). Not to bad for an Air. On a decent Macbook Pro this would be a very workable setup.
Most of the CPU power is going to VirtualDJ by the way, it takes about 30 times more cpu power than MadMapper.
One thing left to test and that is passing the video through a VJ tool like Modul8 or CellDNA first.
