To read a live video stream using Node.js, you can use libraries such as ffmpeg, opencv4nodejs, or node-cv. I'll provide you with a basic example using opencv4nodejs, which is a Node.js wrapper for OpenCV. First, you'll need to install the opencv4nodejs library. Open your terminal and run:npm install opencv4nodejs Now, you can use the following example code to read a live video stream:const cv = require('opencv4nodejs');// Create a video capture objectconst cap = new cv.VideoCapture(0); // Use 0 for the default camera// Check if the camera opened successfullyif (!cap.read) { console.error('Error opening camera.'); process.exit(1);}// Create a window to display the video streamconst window = new cv.NamedWindow('Live Video', cv.WINDOW_AUTOSIZE);// Read frames from the video streamconst readFrame = () => { const frame = cap.read(); // Display the frame window.imshow(frame); // Call the next frame setImmediate(readFrame);};// Start reading framesreadFrame();// Handle window close eventwindow.on('close', () => { // Release the video capture object cap.release(); process.exit(0);}); This code creates a window using opencv4nodejs to display the live video stream from your camera. It continuously reads frames from the camera and displays them in the window. The setImmediate function is used to loop and read the next frame. Remember to change the camera index (0 in this case) if you have multiple cameras or if your camera is at a different index. Keep in mind that you might need to adjust the code based on your specific requirements, and you may need to handle errors and exceptions appropriately in a production environment. read less
