I'm working on stereovision and i had to calibrate a dual webcam setup. And for this I have to take some picture from webcam but i cannot reach or open the cameras. I am on OpenCV 3.0, ubuntu 16 AND I'm programming in C++. I'm using VideoCapture cap(0) to get an image from camera. If i check if it succeded with a if(!cap.isopened), i show that something wrong with the openning of the camera and i get this errror on my terminal
(process:11366): GStreamer-CRITICAL **: gst_element_get_state: assertion 'GST_IS_ELEMENT (element)' failed
I'm sorry for my bad english Thank you for your future response
