Subject: iSite question
I want to write an application that maps streaming video from my
iSite
onto openGL geometry. I can make the geometry, but how do I query
the
iSite for the video?
I assume you mean "iSight". You could use libARvideo from the
ARToolKit project for the frame capture. See
http://artoolkit.sourceforge.net
libARvideo returns video frames in a format designed to be passed off
to OpenGL as a texture.
You could, if you wanted to rewrite libARvideo's improvements over the
Apple samples.
Both call into QuickTime's sequence grabber facility which can handle
any video source, not just iSights.
As does libARvideo.. actually it directly queries the vDig, to work
around performance bottlenecks in the Sequence Grabber.
