NUBOMEDIA Big Picture

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs

API Description

Media API Enables developers consuming the Media Server capabilities among which we can find media transport, media archiving, media processing, media transcoding, and so on

WebRtcPeer API Abstracts the client WebRTC media capabilities, exposing the media capture and communication capabilities of a browser in a seamless way

Repository API Makes possible to access an elastic scalable media repository for archiving media information and meta-information

Signaling API Provides a simple signaling mechanism based on JSON-RPCs for applications

Room API Enables application developers functionalities to create group communication applications adapted to real social interactions

Tree API Allows developers to build video broadcasting web applications

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Media API−Media API allows to Java developers consume the media services provided by Kurento Media Server (KMS)−Concepts:

• Media Element• Media Pipeline

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Media API−KMS instances are provided elastically by NUBOMEDIA

• The number of available KMS instances depends on the PaaS Manager configuration (next section)

−Each KMS has a total amount of available points to create Media Pipelines and Media Elements

• The total points depends on the number of VCPUs of the KMS• The type of the instance can be selected on the PaaS Manager

configuration (next section)

Instance type # VCPUs KMS pointsMedium 2 200

Large 4 400

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Media API−Each KMS is controlled by an instance of KurentoClient

−With each media session an instance of KurentoClient should be created

−The number of available points per KMS decreases with each Media Element creation (scaling in/out)

<dependency> <groupId>org.kurento</groupId> <artifactId>kurento-client</artifactId></dependency>

<dependency> <groupId>de.fhg.fokus.nubomedia</groupId> <artifactId>nubomedia-media-client</artifactId></dependency>

Dependencies (Maven)

KurentoClient kurentoClient = KurentoClient.create();

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Media API−Example: nubomedia-magic-mirror // One KurentoClient instance per sessionKurentoClient kurentoClient = KurentoClient.create();

// Media logic (pipeline and media elements connectivity)MediaPipeline mediaPipeline = kurentoClient.createMediaPipeline();

WebRtcEndpoint webRtcEndpoint = new WebRtcEndpoint.Builder(mediaPipeline).build();FaceOverlayFilter faceOverlayFilter = new FaceOverlayFilter.Builder(mediaPipeline).build();faceOverlayFilter.setOverlayedImage("http://files.kurento.org/img/mario-wings.png", -0.35F, -1.2F, 1.6F, 1.6F);

webRtcEndpoint.connect(faceOverlayFilter);faceOverlayFilter.connect(webRtcEndpoint);

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Repository API−NUBOMEDIA provides access to a Kurento Repository in order to store and recover multimedia streams (and metadata) −The repository is controlled by an instance of RepositoryClient (Java)

<dependency> <groupId>de.fhg.fokus.nubomedia</groupId> <artifactId>nubomedia-media-client</artifactId></dependency><dependency> <groupId>de.fhg.fokus.nubomedia</groupId> <artifactId>nubomedia-repository-client</artifactId></dependency>


RepositoryClient repositoryClient = RepositoryClientProvider.create();

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Repository API−Example: nubomedia-repository-tutorial

The first step is to carry out the WebRTC loopback communication. We can see the live media while it is being recorded in the repository.

After that, we are able to reproduce the recording, reading the media stored in the repository.

https://github.com/nubomedia/nubomedia-repository-tutorial


2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Repository API−Example: nubomedia-repository-tutorial// KurentoClientkurentoClient = KurentoClient.create();

// Media pipelinemediaPipeline = kurentoClient.createMediaPipeline();

// Repository item (recorder)Map<String, String> metadata = Collections.emptyMap();repositoryItemRecorder = repositoryClient.createRepositoryItem(metadata);

// Media elements and connectivitywebRtcEndpoint = new WebRtcEndpoint.Builder(mediaPipeline).build();recorderEndpoint = new RecorderEndpoint.Builder(mediaPipeline, repositoryItemRecorder.getUrl()).withMediaProfile(MediaProfileSpecType.WEBM).build();webRtcEndpoint.connect(webRtcEndpoint);webRtcEndpoint.connect(recorderEndpoint);

// WebRTC negotiationString sdpAnswer = performWebRtcNegotiation(session, sdpOffer);

// Start recordingrecorderEndpoint.record();



2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Repository API−Example: nubomedia-repository-tutorial// KurentoClientkurentoClient = KurentoClient.create();

// Media pipelinemediaPipeline = kurentoClient.createMediaPipeline();

// Repository item (player)RepositoryItemPlayer repositoryItemPlayer = repositoryClient.getReadEndpoint(repositoryItemRecorder.getId());

// Media elements and connectivitywebRtcEndpoint = new WebRtcEndpoint.Builder(mediaPipeline).build();playerEndpoint = new PlayerEndpoint.Builder(mediaPipeline, repositoryItemPlayer.getUrl()) .build();

playerEndpoint.connect(webRtcEndpoint);

// WebRTC negotiationString sdpAnswer = performWebRtcNegotiation(session, sdpOffer);

// Start playingplayerEndpoint.play();



2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - WebRtcPeer API−JavaScript API that abstracts the client RTC media (Media Capture and PeerConnection)

<dependency> <groupId>org.kurento</groupId> <artifactId>kurento-utils-js</artifactId></dependency>

Maven dependency

<script src="js/kurento-utils.js"></script>

var options = { localVideo : videoInput, remoteVideo : videoOutput, onicecandidate : onIceCandidate}

webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv(options, function(error) { if (error) { return console.error(error); } webRtcPeer.generateOffer(onOffer); });}

JavaScript library

Example of use (send-receive)

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Signaling API−NUBOMEDIA capabilities can be accessed through any kind of signaling protocol (e.g. SIP, XMPP or REST)−NUBOMEDIA provides a very signaling protocol based on JSON-RPCs over WebSockets−This API has several components

• Server signaling API• JavaScript client signaling API• Android client signaling API• iOS client signaling API

http://nubomedia.readthedocs.io/en/latest/api/signaling/

http://nubomedia.readthedocs.io/en/latest/api/signaling/

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Room API−The Room API is a high-level communications library that provides capabilities for managing multi-conference WebRTC sessions. It has the following components:

• Room Server: a container-based implementation of the server, uses JSON-RPC over WebSockets for communications with the clients

• Room JavaScript Client: module implementing a Room client for Web applications

• Room Client: a client library for Java web applications or Android clients

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Room API−Example: nubomedia-room-tutorial

<dependency> <groupId>org.kurento</groupId> <artifactId>kurento-room-server</artifactId></dependency><dependency> <groupId>org.kurento</groupId> <artifactId>kurento-room-client-js</artifactId></dependency>


public class SingleKmsManager extends KmsManager {

@Override public KurentoClient getKurentoClient(KurentoClientSessionInfo sessionInfo) throws RoomException { return KurentoClient.create(); }

@Override public boolean destroyWhenUnused() { return true; }

}

2. NUBOMEDIA APIs/SDKsNUBOMEDIA APIs - Tree API−The NUBOMEDIA Tree API allows developers to build WebRTC broadcasting applications−This API is composed by a server and two clients:

• tree-server is a component of the API designed to be deployed and controlled by clients

• tree-client implements a tree client designed to be used in Java web applications or Android applications. The client contains an implementation of JSON-RPC WebSocket protocol implemented by Tree server

• tree-client-js implements a tree client to be used in Single Page Applications (SPA)

1. Introduction2. NUBOMEDIA APIs/SDKs3. NUBOMEDIA PaaS

− Introduction− PaaS GUI

4. Let's get to work

3. NUBOMEDIA PaaSIntroduction−The NUBOMEDIA PaaS manager is a tool aimed to control the way in which the NUBOMEDIA applications are built and deployed inside the NUBOMEDIA PaaS−The capabilities provided by the Paas Manager can be used by developers using the PaaS GUI:

• The PaaS Manager GUI is a web application that allows to use the NUBOMEDIA PaaS Manager

3. NUBOMEDIA PaaSIntroduction−Internally, the NUBOMEDIA PaaS uses Docker containers to deploy applications−Therefore it is a requirement to include a Dockerfile in GitHub repository to be deployed on NUBOMEDIA−Example: FROM nubomedia/apps-baseimage:src

MAINTAINER Nubomedia

ADD keystore.jks /ADD . /home/nubomedia

RUN sudo chown -R nubomedia /home/nubomediaRUN cd /home/nubomedia && mvn compile

ENTRYPOINT cd /home/nubomedia && mvn exec:java

1. Introduction2. NUBOMEDIA APIs/SDKs3. NUBOMEDIA PaaS4. Let's get to work

− Introduction− Server-side− Client-side− Deployment

4. Let's get to workIntroduction−Devil is in the details, and so, we are going to see a complete NUBOMEDIA step by step−This applications the nubomedia-magic-mirror tutorial

https://github.com/nubomedia/nubomedia-magic-mirror/

http://nubomedia.readthedocs.io/en/latest/tutorial/nubomedia-magic-mirror/

4. Let's get to workServer-side−We recommend Spring-Boot as the base technology for NUBOMEDIA applications

• Spring-Boot embeds a Tomcat server in a simple seamless way for developers

• The application is packaged as a runnable JAR, and when this JAR is executed, the Tomcat server is started and the web application automatically deployed

−We recommend Maven as for managing the life-cycle and managing the dependencies of our applications

4. Let's get to workServer-side−The first step is to clone GitHub repository

−We recommend use an IDE to develop applications. For example, Eclipse (importing app as Maven project)

git clone https://github.com/nubomedia/nubomedia-magic-mirror

4. Let's get to workServer-side−First step is understand the pom.xml file:

<parent> <groupId>org.kurento</groupId> <artifactId>kurento-parent-pom</artifactId> <version>6.5.0</version></parent>

<properties>  <nubomedia-media-client.version>1.0.2</nubomedia-media-client.version>

 <start-class>eu.nubomedia.tutorial.magicmirror.MagicMirrorApp</start-class></properties>

Inherit from kurento-parent-pom makes simpler our pom.xml by reusing versions defined in the parent

It’s important declare the fully qualified name of the main class

4. Let's get to workServer-side

<dependencies>  <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-websocket</artifactId> </dependency>

 <dependency> <groupId>org.kurento</groupId> <artifactId>kurento-client</artifactId> </dependency> <dependency> <groupId>org.kurento</groupId> <artifactId>kurento-utils-js</artifactId> </dependency>

 <dependency> <groupId>de.fhg.fokus.nubomedia</groupId> <artifactId>nubomedia-media-client</artifactId> <version>${nubomedia-media-client.version}</version> </dependency></dependencies>

…

…

Dependencies clause is one of the most important. Notice that our app depends on Spring, Kurento, and NUBOMEDIA

4. Let's get to workServer-side−We need to define also the way in which signaling is going to work in our application−For the shake of simplicity, we use a raw WebSocket between the server and client side−We need to define the messages exchanged to carry out the communication about client and server

clientserver

start

startResponse

iceCandidate

onIceCandidate

stop

error

notEnoughResources

Starts a media session

ICE candidates (WebRTC negotiation)

Stops a media session

Error cases

4. Let's get to workServer-side−The class diagram of our application is the following:

MagicMirrorApp

MagicMirrorHandler

UserSession

Main class

Message handler (signaling)

User session (session id, media logic)

4. Let's get to workServer-side

@SpringBootApplication@EnableWebSocketpublic class MagicMirrorApp implements WebSocketConfigurer {

@Bean public MagicMirrorHandler handler() { return new MagicMirrorHandler(); }

@Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { registry.addHandler(handler(), "/magicmirror"); }

public static void main(String[] args) throws Exception { new SpringApplication(MagicMirrorApp.class).run(args); }}

MagicMirrorApp defines the Spring-Boot application and the WebSocket used for signaling ("/magicmirror", managed by MagicMirrorHandler)

4. Let's get to workServer-sidepublic class MagicMirrorHandler extends TextWebSocketHandler {

private final ConcurrentHashMap<String, UserSession> users = new ConcurrentHashMap<>();

@Override public void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception { JsonObject jsonMessage = new GsonBuilder().create().fromJson(message.getPayload(), JsonObject.class); switch (jsonMessage.get("id").getAsString()) { case "start": start(session, jsonMessage); break; case "stop": release(session); break; case "onIceCandidate": onIceCandidate(session, jsonMessage); break; default: error(session, "Invalid message with id " + jsonMessage.get("id").getAsString()); break; } }

MagicMirrorHandler manages signaling messages. It keeps a collection of user sessions (thread-safe map users)

4. Let's get to workServer-sidepublic class UserSession {

public String startSession(final WebSocketSession session, String sdpOffer) { // One KurentoClient instance per session kurentoClient = KurentoClient.create(); log.info("Created kurentoClient (session {})", sessionId);

// Media logic (pipeline and media elements connectivity) mediaPipeline = kurentoClient.createMediaPipeline(); log.info("Created Media Pipeline {} (session {})", mediaPipeline.getId(), sessionId);

webRtcEndpoint = new WebRtcEndpoint.Builder(mediaPipeline).build(); FaceOverlayFilter faceOverlayFilter = new FaceOverlayFilter.Builder(mediaPipeline).build(); faceOverlayFilter.setOverlayedImage("http://files.kurento.org/img/mario-wings.png", -0.35F, -1.2F, 1.6F, 1.6F); webRtcEndpoint.connect(faceOverlayFilter); faceOverlayFilter.connect(webRtcEndpoint);

// WebRTC negotiation String sdpAnswer = webRtcEndpoint.processOffer(sdpOffer); webRtcEndpoint.gatherCandidates();

return sdpAnswer; }

UserSession handles media logic (media pipeline, media elements, WebRTC negotiation…)

4. Let's get to workServer-side−As of Chrome 47, access to user media can only be done by secure apps (HTTPS), and so, it is needed a Java keystore

server.port: 8443server.ssl.key-store: keystore.jksserver.ssl.key-store-password: kurentoserver.ssl.keyStoreType: JKSserver.ssl.keyAlias: kurento-selfsigned

application.properties

http://doc-kurento.readthedocs.io/en/stable/mastering/securing-kurento-applications.html

4. Let's get to workClient-side−Client-side dependencies are handled by Bower−Our bower.json file contains:

−In addition the file .bowerrc configures the target path for the JavaScript libraries

"dependencies": { "bootstrap": "~3.3.0", "ekko-lightbox": "~3.1.4", "adapter.js": "v0.2.9", "demo-console": "1.5.1" }

{ "directory" : "static/bower_components"}

4. Let's get to workClient-side−The app has been implemented as a SPA (single page application) which contains a single HTML

<!DOCTYPE html><html><head><link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.min.css"><link rel="stylesheet" href="bower_components/ekko-lightbox/dist/ekko-lightbox.min.css"><link rel="stylesheet" href="bower_components/demo-console/index.css"><link rel="stylesheet" href="css/styles.css">

<script src="js/kurento-utils.js"></script><script src="js/index.js"></script><title>NUBOMEDIA Tutorial: WebRTC Magic Mirror</title></head>

JavaScript/CSS are linked here. Using Bootstrap to provide responsive design

4. Let's get to workClient-side−A JavaScript file contains the client-side logic (message handling and WebRtcPeer use)

var ws = new WebSocket('wss://' + location.host + '/magicmirror');

ws.onmessage = function(message) { var parsedMessage = JSON.parse(message.data); switch (parsedMessage.id) { case 'startResponse': startResponse(parsedMessage); break; case 'error': onError("Error message from server: " + parsedMessage.message); stop(false); break; case 'iceCandidate': webRtcPeer.addIceCandidate(parsedMessage.candidate, function(error) { if (error) return console.error("Error adding candidate: " + error); }); break; // ... }}

4. Let's get to workClient-side−A JavaScript file contains the client-side logic (message handling and WebRtcPeer use)

var webRtcPeer;

function start() { var options = { localVideo : videoInput, remoteVideo : videoOutput, onicecandidate : onIceCandidate } webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv(options, function(error) { if (error) { return console.error(error); } webRtcPeer.generateOffer(onOffer); });}

4. Let's get to workDeployment−We need a Dockerfile to deploy our app

FROM nubomedia/apps-baseimage:src

MAINTAINER Nubomedia

ADD keystore.jks /ADD . /home/nubomedia

RUN sudo chown -R nubomedia /home/nubomediaRUN cd /home/nubomedia && mvn compile

ENTRYPOINT cd /home/nubomedia && mvn exec:java

4. Let's get to workDeployment−Finally we can deploy our app in the NUBOMEDIA PaaS Manager:

4. Let's get to workDeployment−The app changes its state, from CREATED to RUNNING (it takes a couple of minutes to finish):

4. Let's get to workDeployment−We can trace two types of logs: build and app
