To capture a video stream from a Logitech C270 HD Webcam using libusb, you'll need to interface with the webcam's USB Video Class (UVC) interface, as the C270 is a UVC-compliant device. Below is a step-by-step guide to achieve this. Note that this process requires familiarity with C/C++ programming, USB protocols, and handling video data (e.g., MJPEG or YUYV formats). The approach assumes you're working on a Linux system, as libusb is commonly used there, but it can be adapted for other platforms.Prerequisites
- Install libusb: Ensure libusb-1.0 is installed (sudo apt install libusb-1.0-0-dev on Debian/Ubuntu or equivalent).
- Development Environment: Set up a C/C++ environment with a compiler (e.g., gcc) and necessary headers.
- Permissions: Ensure you have permissions to access the webcam (e.g., add your user to the video group or run as root, though root is not recommended).
- Dependencies: Optionally, install v4l2loopback to create a virtual video device for testing or piping the stream to other appl
