easy_onvif 0.0.8

A pure Dart library designed primarily for command line automation of Onvif compatible devices, but can be used anywhere Dart is used.

ONVIF Client protocol Profile S (Live Streaming) Dart implementation.

This is a wrapper to ONVIF protocol which allows you to get information about your NVT (network video transmitter) device, its media sources, control PTZ (pan-tilt-zoom) movements and manage presets. It will also allow you to get information about your NVR (network video recorder).

Getting Started

In your project add the dependency:

dependencies:
  ...
  easy_onvif: ^0.0.8

For help getting started with dart, check out these guides.

Usage Example

Import the easy_onvif library.

import 'package:easy_onvif/onvif.dart';

Connecting to an Onvif device

var onvif =
	Onvif(host: '[your onvif device ip]', username: '[theUser]', password: '[thePassword]');

await onvif.initialize();

Interacting with the device through Onvif operations

Refer to the tables below for the supported operations.

Through the deviceManagement operations you can get information about the connected device.

var deviceInfo = await onvif.deviceManagement.getDeviceInformation();

print(deviceInfo.model);

Many operations require you to supply a profileToken which can be retrieved through media operations.

var profiles = await onvif.media.getProfiles();

profiles.forEach((element) {
	print(element.name + ' ' + element.token);
});

var profileToken = profiles[0].token;

With the ptz operations you can get a list of camera presets from the connected device.

var presets = await onvif.ptz.getPresets(profileToken);

//get a specific preset
var preset = presets[11];

//print the preset values
print(
	'preset: ${preset.position.panTilt?.x}  ${preset.position.panTilt?.y}  ${preset.position.zoom?.x}');

//use the GotoPreset operation to point the camera to the given preset
await onvif.ptz.gotoPreset(profileToken, preset);

Be sure to look through the API Reference for information about the parameters required for the supported Onvif operations.
