USB camera not detected, but seen in Device Manager
Dear all,
I am using openCV 2.2 for color tracking, and I have come across a problem.
When I am using the internal Lenovo webcam it works fine, but when I try to switch to external cam it's not detecting it.
I have tried with two different webcams (Microsoft and Logitech) but still no success.
I have also made sure that the camera is seen in the device manager.
I have also tried to disable the internal Lenovo webcam, and select
capture = cvCreateCameraCapture(-1);
but with no luck.
I get this error sometimes:
OpenCV Error: Assertion failed (func != 0) in unknown function, file ..\..\..\..\ocv\opencv\modules\core\src\copy.cpp, line 448
Please, if you have any suggestions, thank you in advance.
BR, Blaz
