cam2ip

Turn any webcam into an IP camera.

Example (in web browser):

http://localhost:56000/html

or

http://localhost:56000/mjpeg

You can also use apps like ffplay or vlc:

ffplay -i http://localhost:56000/mjpeg

Requirements

• 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
