-imaging       Enable Imaging (default: true)
-events        Enable Events (default: false)
-info          Show info and exit
-version       Show version and exit

Usage Examples

Start Server with Defaults

onvif-server

Custom Configuration

onvif-server -profiles 5 -username admin -password mypass -port 9000

Library Usage

package main

import (
    "context"
    "github.com/0x524a/onvif-go/server"
)

func main() {
    srv, _ := server.New(server.DefaultConfig())
    srv.Start(context.Background())
}

Test with ONVIF Client

client, _ := onvif.NewClient(
    "http://localhost:8080/onvif/device_service",
    onvif.WithCredentials("admin", "admin"),
)

profiles, _ := client.GetProfiles(ctx)
for _, profile := range profiles {
    streamURI, _ := client.GetStreamURI(ctx, profile.Token)
    fmt.Println(streamURI.URI)
}

Testing
