Capture live video from a DSLR in C++/OpenCV

Question

My C++/OpenCV app runs well when I use a USB webcam to capture live video stream.

However, when I connect a Canon 5Dii with live video it doesn't find the camera.

The Canon utility captures the video well.

Should I use the VideoCapture cap(1)?

Answer 1

You should use the official Canon Digital Camera SDK to grab frames from 5D II. There are some sample apps for connecting to the camera (as a source device) from your PC and then receiving camera events/images. Keep in mind that you need to sign up and be approved by Canon to use the SDK.
