cam2ip

On Linux/RPi native Go Video4Linux (V4L) implementation is used to capture images.
On Windows Media Foundation is used (or Video for Windows with the vfw build tag).
On macOS AVFoundation is used over purego, no cgo required.

Build tags

vfw - on Windows, use Video for Windows to access camera instead of the default Media Foundation
libjpeg - build with libjpeg (go-libjpeg) instead of native image/jpeg
