2012-12-22 22:03:11 -0600 | asked a question | wireless web cam thru ip Hi there, i am a novice towards opencv. i need some help. i am trying to connect to a wireless webcam d-link dcs-930. But the screen didnt shows up. The code is just a simple code to detect circle. The code works fine when i use my laptop webcam. My background on opencv, 3 weeks ago i tried to follow the 2.4.3 tutorial and install cmake,cuda,python etc etc but in the end, during the visual studio build, i encounter problems. Then i was told that i dont have to do all that unless i created new library. so now i am just using opencv 2.4.3. Hope i can get help in this forum. thanks. ************CODE***************** include <c:\opencv243\include\opencv\cv.h>include <c:\opencv243\include\opencv\highgui.h>include <math.h>int main( int argc, char **argv ) { CvCapture *capture = 0; IplImage *img = 0; int key = 0; CvFont font; cvInitFont(&font, CV_FONT_HERSHEY_PLAIN,1.0,1.0,0,1,CV_AA); //capture = cvCreateFileCapture("http://192.168.0.20/image/jpeg.cgi"); capture = cvCreateFileCapture("http://192.168.0.20/image/mjpeg.cgi"); //capture = cvCreateFileCapture("rtsp://192.168.0.20/img/media.sav"); //capture = cvCaptureFromFile("http://192.168.0.20/video/mjpg.cgi"); //capture = cvCaptureFromCAM( 0 ); } **********output***************** 'mynewproject.exe': Loaded 'C:\Users\Steven\Documents\Visual Studio 2010\Projects\mynewproject\x64\Debug\mynewproject.exe', Symbols loaded.
