I want to read from IP camera with openCV, IP camera provides a RTSP output rtsp://ip:port/video.3gp but cvCaptureFromFile("rtsp://ip:port/video.3gp"); shows a blank screen, the alternative solution is using using JPEG output, its url is http://ip/jpg/image.jpg and will every 50ms, but also cvCaptureFromFile("http://ip/jpg/image.jpg"); returns blank screen; I dont't know do I use it in right way or not.

  • Why do you expect opencv to handle URLs? Use some other lib (e.g. curl) to fetch the image, then use opencv to open it. – etarion Aug 15 '11 at 10:59
  • honestly, It's first time I'm writing C++ code, I have VB.net programming experience; I don't know how to deal with curl type and IpImage – Maysam Aug 15 '11 at 11:12

I've managed to find a way to load images into OpenCV right away from the image URL. Find out how to do it here: http://techify.giridharsweb.com/2012/08/05/read-image-from-url-into-opencv/
