If you are making your own application you can create an open gl
context and pixel format that is full screen capable and use my QC
plugin that takes screenshots on the GPU at full framerate and outputs
a texture (its very very fast).

Is there any way to take the visual output from an app or from OSX

Something like this would work, but it may be slow depending on how
NSBitmapImageRep is implemented (and I really don't know.)

If it has to download any content off the GPU to the CPU, then QC
will upload it back then it will be less than optimal. If your
application doesn't have high framerate animations or audio sync'd
video, then that shouldn't be a problem.
There may be other solutions, that's just the first one that came to
mind.
