Video capture on MacOS

Question

Hi to all

I'm wrtiting a C++ application with Trolltech QT Library and I need to capture video stream from a camera and some medical instrumentations.

What kind of hardware can I use to do this? I've tried with OpenCV but it doesn't recognize my EyeTV 250.

Can I use Pinnacle Video capture for Mac?

thanks, Andrea

Answer 1

I believe that Qt delegates to QuickTime for media on OS X. I'd therefore expect that any hardware supported by QuickTime is in play. If you're willing to be locked to OS X, using the native API will likely be much easier. QTKit, the Objective-C API for QuickTime is new with Leopard (OS X 10.5) and is very good. You'll likely want to start with QTKit's Capture API. Since you're working with C++, you'll also want to learn about Objective-C++ for building the connection between QTKit and your code.

Try openCV, there is a good project here : http://code.google.com/p/opencv-cocoa/ there are c++ class.
