Turn any webcam into an IP camera

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

• libjpeg-turbo (use -tags jpeg to build without CGo)
• 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

• cv2 - build with OpenCV 2.x (go-opencv)
• cv4 - build with OpenCV 4.x (gocv)
• jpeg - build with native Go image/jpeg instead of libjpeg-turbo

Download

Binaries are compiled with static OpenCV/libjpeg-turbo libraries, they should just work:

• Linux 64bit
• Linux 64bit OpenCV
• macOS 64bit OpenCV
• RPi 32bit
• RPi 32bit OpenCV
• RPi 32bit Static
• RPi3 32bit
• RPi3 32bit OpenCV
• Windows 32bit
• Windows 32bit OpenCV
• Windows 64bit
• Windows 64bit OpenCV

Installation

go get -v github.com/gen2brain/cam2ip/cmd/cam2ip

This will install app in $GOPATH/bin/cam2ip.

Run in Docker container

docker run --device=/dev/video0:/dev/video0 -p56000:56000 -it gen2brain/cam2ip # on RPi use gen2brain/cam2ip:arm
