Capture camera Image using ycbcr format

Question

I am using OpenCV to capture live from several cameras:

capture = cvCaptureFromCAM(cameraNo)

Now, I need to convert images to YCbCr color space. I realized that I could use cvtColor to convert an image to another color space. However, the process is too expensive to do after capturing the image. It includes a matrix transformation for every pixel;

I wonder if there is a property setting or another way to perform the capturing (perhaps on hardware level) on the desired color space? Or the only way is to capture and convert?

Answer 1

No, unfortunately you can't do that with OpenCV. The only way is to capture and convert.
