UPnPLite

The UPnPLite is a high-performance, lite UPnP/DLNA framework for discovering and controlling media devices over the network.

Currently, next platforms are supported:

• .NET 4.5
• WinRT
• Windows Phone 8

Prerequisites

In order to build sources, be sure that next prerequisites are installed:

• .NET Framework 4.5
• Windows Phone 8 SDK
• Reactive Extensions v2.0.20823 and upper

Installation

The installation process is quite manual at the moment, but it will be improved subsequently.

To start using the UPnPLite, please follow next steps:

• Download sources git clone git://github.com/SNIKO/UPnPLite.git

• Build \sources\UPnPLite.sln solution;

• Run RegisterBinaries.bat script. It will register binaries into GAC to make them available in "Reference Manager";

• Add SV.UPnPLite.dll assembly to your project and enjoy using it.

Usage

UPnP Examples

• Searching for UPnP devices:

var devicesDiscovery = new CommonUPnPDevicesDiscovery();

// Receiving notifications about new devices added to a network
devicesDiscovery.DevicesActivity.Where(e => e.Activity == DeviceActivity.Available).Subscribe(e =>
{	
	Console.WriteLine("{0} found", e.Device.FriendlyName);
});

// Receiving notifications about devices left the network
devicesDiscovery.DevicesActivity.Where(e => e.Activity == DeviceActivity.Gone).Subscribe(e =>
{
	Console.WriteLine("{0} gone", e.Device.FriendlyName);
});

//  Receiving notifications about new devices of specific type added to the network
var newMediaServers = from activityInfo in devicesDiscovery.DevicesActivity
                      where activityInfo.Activity == DeviceActivity.Available && activityInfo.Device.DeviceType == "urn:schemas-upnp-org:device:MediaServer"
                      select activityInfo.Device;

newMediaServers.Subscribe(server => 
{
	Console.WriteLine("{0} found", server.FriendlyName);
});

// Getting currently available devices
var devices = devicesDiscovery.DiscoveredDevices;

• Invoking action on UPnP service:

var devicesDiscovery = new CommonUPnPDevicesDiscovery();
var rendererDevice = devicesDiscovery.DiscoveredDevices.First(device => device.DeviceType == "urn:schemas-upnp-org:device:MediaRenderer");
var renderingControlService = rendererDevice.Services.First(service => service.ServiceType == "urn:upnp-org:serviceId:RenderingControl");
			
var args = new Dictionary<string, object>();
args["InstanceID"] = 0;
args["Channel"] = "Master";
args["DesiredVolume"] = 80;

var response = await renderingControlService.InvokeActionAsync("SetVolume", args);

DLNA Examples

• Searching for media devices:

var mediaServersDiscovery = new MediaServersDiscovery();
var mediaRenderersDiscovery = new MediaRenderersDiscovery();

// Enumerating currently available servers
foreach (var server in mediaServersDiscovery.DiscoveredDevices)
{
	Console.WriteLine("Server found: {0}", server.FriendlyName);
}

// Receiving notifications about new media servers added to a network
mediaServersDiscovery.DevicesActivity.Where(e => e.Activity == DeviceActivity.Available).Subscribe(e =>
{
	Console.WriteLine("Server found: {0}", e.Device.FriendlyName);
});

// Receiving notifications about media renderers left the network
mediaRenderersDiscovery.DevicesActivity.Where(e => e.Activity == DeviceActivity.Gone).Subscribe(e =>
{
	Console.WriteLine("Renderer gone: {0}", e.Device.FriendlyName);
});

• Browsing media on MediaServer:

var mediaServersDiscovery = new MediaServersDiscovery();
var server = mediaServersDiscovery.DiscoveredDevices.First();

// Requesting root media objects
var rootObjects = await server.BrowseAsync();
var rootContainers = rootObjects.OfType<MediaContainer>();
var rootMediaItems = rootObjects.OfType<MediaItem>();			

// Requesting media objects from child container
var containerToBrowse = rootContainers.First();
var childContainerObjects = await server.BrowseAsync(containerToBrowse);

• Searching for media items on MediaServer:

var mediaServersDiscovery = new MediaServersDiscovery();
var server = mediaServersDiscovery.DiscoveredDevices.First();

// Find all music tracks
var musicTracks = await server.SearchAsync<MusicTrack>();
foreach (var track in musicTracks)
{
	Console.WriteLine("Title={0}, Album={1}, Artist={2}", track.Title, track.Album, track.Artist);
}

// Find all video items
var videos = await server.SearchAsync<VideoItem>();
foreach (var video in videos)
{
	Console.WriteLine("Title={0}, Genre={1}", video.Title, video.Genre);
}

• Playing the media on MediaRenderer:

var mediaServersDiscovery = new MediaServersDiscovery();
var mediaRenderersDiscovery = new MediaRenderersDiscovery();
			
var server = mediaServersDiscovery.DiscoveredDevices.First();
var renderer = mediaRenderersDiscovery.DiscoveredDevices.First();

var musicTracks = await server.SearchAsync<MusicTrack>();
var track = musicTracks.First();
						
await renderer.OpenAsync(track);
await renderer.PlayAsync();

// Subscribing for a playback position change
renderer.PositionChanges.Subscribe(position =>
{
	Console.WriteLine("Position changed: {0}", position);
});

// Subscribing for a playback state change
renderer.StateChanges.Subscribe(state =>
{
	Console.WriteLine("Playback state changed: {0}", state);
});
