title: How do you capture an image from a webcam in python WITHOUT OpenCV
body: <p>I'm programming in python on a Raspberry Pi Zero and I want to capture an image from a USB webcam and I can't find a way of doing this without OpenCV. I don't want to use OpenCV because it's way overkill in features and size for what I'm doing (just taking a raw image from a camera, no processing) and it will take 10+ hours to compile on a Pi Zero. Please tell me there is another way. Pygame was mentioned in another similar question but that only works on Windows. Any ideas or must I sacrifice a half GB of flash to the OpenCV gods and spend 10+ hours compiling its code just to take an image?</p>
