回答1:

Capture _Capture = new Emgu.CV.CvInvoke.cvCreateFileCapture("http://username:pass@cam_address/axis-cgi/mjpg/video.cgi?resolution=640x480&req_fps=30&.mjpg");

I didn't test but may be this code snippet or approach can help you. For OpenCV example you can examine this page: OpenCV with Network Cameras

And you can examine this method's wiki page: http://www.emgu.com/wiki/files/2.3.0/document/html/a26a5e9d-53d7-633a-5d50-508aa22dd1fd.htm

回答2:

If you are using Emgu 3.1 then try this:

Capture cameraCapture
cameraCapture = new Capture("http://user:passwd@http://169.254.255.253");
Mat frame = cameraCapture.QueryFrame();
imageBox1.Image = frame;

here is the Capture Class Reference:

Hope it helps.
