ip-camera

I have earlier programmed USB webcam, where the sole aim is to get the live frames from the camera and display in a window. I used cvCaptureFromCAM for that purpose, which worked fine for USB Camera(see code below). I want to know how do I capture frames from a Gigabit Ethernet camera? I guess I need to capture frames from some default IP address using some API. Can some one point me to right direction? I will be using C++ with OpenCV on Windows 7 on an Intel i3 processor. #include "cv.h" #include "highgui.h" #include <stdio.h> // A Simple Camera Capture Framework int main() { CvCapture*

The code given below is for accessing an Axis IP camera using OpenCV. On running the program it first displays "Error in opening cap_ffmpeg_impl..." and then it displays Camera not found. #include <opencv\cv.h> #include <opencv2\highgui\highgui.hpp> #include <opencv2\imgproc\imgproc.hpp> #include <iostream> #include <stdio.h> using namespace std; using namespace cv; int main() { Mat frame; namedWindow("video", 1); VideoCapture cap("http://IPADDRESS/video.mjpg"); if(!cap.isOpened()) { cout<<"Camera not found"<<endl; getchar(); return -1; } while ( cap.isOpened() ) { cap >> frame; if(frame.empty

I am working on one application where I want to use IP camera for displaying video streaming and and some other major operations on image captured by the IP Camera . Libraries used in Camera capture For Camera Capture : Emgu.CV Library Below is the code which I am using in C#. Variable Declaration private Capture capture; //takes images from camera as image frames private Emgu.CV.UI.ImageBox img; // Dynamic Picture Controls private int nCam; // no of cameras Code for Processing Image private void ProcessFrame(object sender, EventArgs arg) { try { // Live Streaming Display Image<Bgr, Byte>

I'm trying to get video from IP camera in emgu, I could display video in the browser from " http://169.254.255.253 " IP, but how could I display this from emgu? please, it's essential for me. Kerberos 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

How do I access my IP Camera stream? Code for displaying a standard webcam stream is import numpy as np import cv2 cap = cv2.VideoCapture(0) while(True): ret, frame = cap.read() cv2.imshow('frame',frame) if cv2.waitKey(1) & 0xFF == ord('q'): break cap.release() cv2.destroyAllWindows() How do I do the same exact thing but with the IP Camera? My system: Python 2.7.14 OpenCV 2.4.9 Teledyne Dalsa Genie Nano XL Camera Help will be highly appreciated An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture . Usually, RTSP or HTTP

I want to use an IP camera with webrtc. However webrtc seems to support only webcams. So I try to convert the IP camera's stream to a virtual webcam. I found software like IP Camera Adapter , but they don't work well (2-3 frames per second and delay of 2 seconds) and they work only on Windows, I prefer use Linux (if possible). I try ffmpeg/avconv: firstly, I created a virtual device with v4l2loopback (the command was: sudo modprobe v4l2loopback ). The virtual device is detected and can be feed with a video (.avi) with a command like: ffmpeg -re -i testsrc.avi -f v4l2 /dev/video1 the stream
