Researching computer vision topics, I often need to grab images/video from webcams and video acquisition hardware, and most of times I use OpenCV default camera framework. However, for recent projects I had to handle camera's properties more in depth (especially to handle fps), and OpenCV resulted bugged and inappropriate. I've spent a day searching the net for an easy interface (eg, which allows you to write a camera-preview app less than 20 lines of code long), with basic functions to handle settings, but I couldn't find any. At last I've downloaded a sample v4l2 demo app (700-800 lines of code, but I had already worked with v4l before) and built a wrapper class around it, building the library I had looked for. Now I'm releasing it, for all those coders who need it and don't have time
