webcam

Is it currently possible to create a flash free live webcam chat with HTML5? If so, how can I go about doing this? samccone no It is in the html5 draft http://www.whatwg.org/specs/web-apps/current-work/complete/video-conferencing-and-peer-to-peer-communication.html#obtaining-local-multimedia-content here is a much deeper conversion about this issue What's the status of the HTML 5 <video> tag and webcam integration? and here is a solution that works using flash http://code.google.com/p/jpegcam/ This is now possible in Chrome and Opera: filtering a webcam using getUserMedia and HTML5 canvas and

I am trying to set OpenCv up for my final year project and have run into a couple of problems. I successfully got it set up in Ubuntu following this tutorial. The problem I am having now is keeping this sample program running. The program is face detection using a webcam. It runs fine for 3 or 4 seconds and then the capture gets stuck with a single frame in the window. The console displays the following output. tom@ubuntu:~/College/opencv/faceDetect_sample$ make ./faceDetect --cascade="haarcascade_frontalface_alt.xml" --nested-cascade="haarcascade_eye_tree_eyeglasses.xml" VIDIOC_QUERYMENU:

I'd like to allow users to record videos directly from their webcam. I haven't done much work with PHP but am stuck with it for this project. We currently have a system in place for video uploading and encoding, but nothing to actually access a user's webcam. How would you recommend I proceed? Webcams aren't available to HTML or JavaScript/DOM in any browsers that I know of, so you're going to end up dependent on some sort of plugin. I'd recommend you start your search with Adobe Flash/Flex, though It's possible that Microsoft Silverlight is able to do the same thing. Flex is a bit more

I would like to access my webcam from Python. I tried using the VideoCapture extension ( tutorial ), but that didn't work very well for me, I had to work around some problems such as it's a bit slow with resolutions >320x230, and sometimes it returns None for no apparent reason. Is there a better way to access my webcam from Python? John Montgomery OpenCV has support for getting data from a webcam, and it comes with Python wrappers by default, you also need to install numpy for the OpenCV Python extension (called cv2 ) to work. As of 2019, you can install both of these libraries with pip: pip

I am trying to open the webcam and display a short capture with OpenCV. I am currently working on Xcode, with C++ language. The code is pretty simple: #include <iostream> #include <opencv2/opencv.hpp> using namespace std; using namespace cv; int main(int argc, const char * argv[]) { // variable initialization Mat frame; VideoCapture cap; // 0 is the webcam // try to open camera cap.open(0); if (!cap.isOpened()) return -1; // check if there is no video or no way to display it // create a window and display the video capture namedWindow("Video Capture", CV_WINDOW_AUTOSIZE); for (int i=0; i<100;

I want to draw/paint on a webcam screen using OpenCV. Since I'm reading from a cam, the frames are constantly changing, so I'm trying to figure out a way to keep or save the drawing on the current frame and use it for the next frame. The code below allows you to draw on the screen but when it gets the next frame, the drawing is gone and it starts over. Could someone please help me ... Thanks. CvCapture *input; input = cvCaptureFromCAM( 0 ); cvSetMouseCallback("Demo",&on_mouse, 0); for(;;) { frame = cvQueryFrame(input); if(!image) { image = cvCreateImage( cvSize(frame->width, frame->height),
