- Install GoCV, full instruction here:
go get -u -d gocv.io/x/gocv
$GOPATH may be not set, but the rest of the path is fine (search for the right path on your system):
cd $GOPATH/src/gocv.io/x/gocv
This takes a few minutes:
make install

go build . && ./termcam 0

- Looks like there's no good way to avoid extra line below the picture, otherwise scrolling happens

error reading from webcam: empty frame. You may want to remove the line, which prints this error to avoid flickering. I've left it for diagnostic purposes.
