JavaScript Kurento Client for Bower

The project contains the implementation of the JavaScript Kurento Client for [Bower].

The source code of this project can be cloned from the GitHub repository.

Installation instructions

Be sure to have installed Node.js and [Bower] in your system:

curl -sL https://deb.nodesource.com/setup_4.x | sudo bash -
sudo apt-get install -y nodejs
sudo npm install -g bower

To install the library, it's recommended to do that from the [Bower repository] :

bower install kurento-client

Alternatively, you can download the code using git and install manually its dependencies:

git clone https://github.com/Kurento/kurento-client-bower
cd kurento-client-bower
bower install

How to create a basic pipeline

For tutorial purposes, we are going to create a basic pipeline that play a video file from its URL and stream it over HTTP :

1. Create an instance of the KurentoClient class that will manage the connection with the Kurento Media Server, so you'll need to provide the URI of its WebSocket endpoint. Alternatively, instead of using a constructor, you can also provide success and error callbacks:

   var kurento = kurentoClient.KurentoClient(ws_uri);
   
   kurento.then(function(kurento)
   {
     // Connection success
     …
   },
   function(error)
   {
     // Connection error
     …
   });

   kurentoClient.KurentoClient(ws_uri, function(kurento)
   {
     // Connection success
     …
   },
   function(error)
   {
     // Connection error
     …
   });

2. Create a pipeline. This will host and connect the diferent elements. In case of error, it will be notified on the error parameter of the callback, otherwise this will be null as it's common on Node.js style APIs:

   kurento.create('MediaPipeline', function(error, pipeline)
   {
     …
   });

3. Create the elements. The player need an object with the URL of the video, and we'll also subscribe to the 'EndOfStream' event of the HTTP stream:

   pipeline.create('PlayerEndpoint',
   {uri: "https://ci.kurento.com/video/format/small.webm"},
   function(error, player)
   {
     …
   });
   
   pipeline.create('HttpGetEndpoint', function(error, httpGet)
   {
     httpGet.on('EndOfStream', function(event)
     {
       …
     });
   
     …
   });

4. Connect the elements, so the media stream can flow between them:

   player.connect(httpGet, function(error, pipeline)
   {
     …
   });

5. Get the URL where the media stream will be available:

   httpGet.getUrl(function(error, url)
   {
     …
   });

6. Start the reproduction of the media:

   player.play(function(error)
   {
     …
   });
