Hi,
OpenCV fails to open Aravis camera this way:
VideoCapture cap("Camera1", cv::CAP_ARAVIS);
Camera1 is id string of the camera. I have got two TiS 33GX236 connected via PoE switch. It's always failing to open the camera.
Is there way to open Aravis camera straight from opencv VideoCapture?
My opencv build:
opencv_version -v
