Well, no Video Input patch is exists with CIFilters, maybe you are talking about Quartz Composer?
Anyway, you will need an OpenGL context for the CIFilters, but that should not be a problem - just don’t forget to set the NSOpenGLPFAOffScreen attribute when you will create your NSOpenGLContext instance. Or you can use a CG context too - but that depends on where your image data come from. > On 03 Nov 2014, at 21:48, Carl Hoefs <newsli...@autonomy.caltech.edu> wrote: > > Awesome! > > The only general restriction would be in using something like the Video Input > patch, correct?
