2012-11-02 18:00:25 -0600 | answered a question | Camera is not working in OpenCV on Ubuntu 12.04 with version 2.3.1 or 2.4.2 Try to install some/all packages from: http://opencv.willowgarage.com/wiki/InstallGuide
And after installing it, remember to rebuild OpenCV. I have the same problem. |
2012-11-02 17:53:37 -0600 | answered a question | Ip / network camera access. At first you must know the URL for snap (MJPEG) e.g. cvCaptureFromFile(http://ip_addr/snap.jpg); in C. The tail "/snap.jpg" is in Bosch Dinion Ip cameras. In my case it method only works (Linux, ffmpeg + h264 codecs installed), some cameras have problem with encoders and cooperative with installed codecs in system e.g. Bosch support as i saw only windows. In one of my programs work this function, it's mixed C & C++ operators, in other way it won't work... Mat GetImage(const char *CameraIP){ } For live stream: 1)C: cvCaptureFromCAM(address); // open stream cvQueryFrame(CvCapture* capture); // get frame 2)C++ vcap.open(videoStreamAddress); // open stream vcap.read(image); // get frame If you work on linux, and have tried a lot in other ways to resolve the problem, feel free to write about it. I have read a lot of infos that for RTSP streaming from IP cameras are good framework POCO ([http://pocoproject.org/]). Good luck |
