One more SampleCamCalib Topic

Jul 9, 2010 at 4:10 AM

I know that this might be brushed off since it's an ALVAR issue, but nobody is responding to my emails and there is no forum or troubleshooting over there.

When running the SampleCamCalib demo, I get the error "Could not initialize the selected capture backend."

The other samples (that don't require calib.xml) work fine.  This is my last resort, and any help would be appreciated.

Actually, nevermind,  they just got back to me.

i am having the same problem. how did you fix it?

ok i figured it out. I just went into the code, commented out the Capture* cap =NULL; and uncommented one of the capture methods. Highgui worked for me but the others didn't. Search for "Could not initialize the selected capture backend." in SampleCamCalib.cpp. its just above that.

Please uncomment at 

Capture *cap = CaptureFactory::CreateCapture(CaptureFactory::CvCam);
