go-visca

Easily control VISCA-Over-IP Cameras!

Getting Started

import (
    "fmt"

    visca "git.sr.ht/~gc/go-visca"
)

...

cam := visca.Connect("192.168.1.180", 52381)
defer cam.Close()

panTilt := cam.PanTilt(1000, 0, 24, 24)

pt := cam.PanTilt(preset.Pan, preset.Tilt, 24, 24)
z := cam.Zoom(preset.Zoom)
errPanTilt, errZoom := <-pt, <-z
if errPanTilt == nil && errZoom == nil {
    fmt.Printf("Success")
    return
}

fmt.Printf("Error: %s, %s", errPanTile, errZoom)

See Visca IP Web for more in-depth usage examples.
