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 V4L implementation is used to capture images.
• On Windows Video for Windows (VfW) framework is used over win32 API.

Build tags

• opencv - use OpenCV library to access camera (gocv)
• libjpeg - build with libjpeg (go-libjpeg) instead of native image/jpeg
• jpegli - build with jpegli (jpegli) instead of native image/jpeg
