README

Golang lib for camera capture

Demo

Install

go get -u github.com/bububa/camera

• libjpeg-turbo (use -tags jpeg to build without CGo)
• On Linux/RPi native Go V4L implementation is used to capture images.

Build tags

• cv4 - build with OpenCV 4.x (gocv)
• jpeg - build with native Go image/jpeg instead of libjpeg-turbo
• android - build for Android
