upnp-mediarenderer-client

An UPnP/DLNA MediaRenderer client

This module allows you to control an UPnP/DLNA MediaRenderer directly (usually your TV set). It implements load, play, pause, stop and seek commands.

Events coming from the MediaRenderer (ie. fired from the TV remote) such as playing, paused, stopped can be listened to.

External subtitles are supported through DIDL-Lite metadata, but be aware that some MediaRenderers require the HTTP server serving the media file to return specific headers as illustrated in this gist. Also, some MediaRenderers don't support external subtitles at all.

Installation

$ npm install upnp-mediarenderer-client

Usage

var MediaRendererClient = require('upnp-mediarenderer-client');
 
// Instanciate a client with a device description URL (discovered by SSDP)
var client = new MediaRendererClient('http://192.168.1.50:4873/foo.xml');
 
// Load a stream with subtitles and play it immediately
var options = { 
  autoplay: true,
  contentType: 'video/avi',
  metadata: {
    title: 'Some Movie Title',
    creator: 'John Doe',
    type: 'video', // can be 'video', 'audio' or 'image'
    subtitlesUrl: 'http://url.to.some/subtitles.srt'
  }
};
 
client.load('http://url.to.some/stream.avi', options, function(err, result) {
  if(err) throw err;
  console.log('playing ...');
});
 
// Pause the current playing stream
client.pause();
 
// Unpause
client.play();
 
// Stop
client.stop();
 
// Seek to 10 minutes
client.seek(10 * 60);
 
// Get the volume
client.getVolume(function(err, volume) {
  if(err) throw err;
  console.log(volume); // the volume range is 0-100
});
 
// Set the volume
client.setVolume(40, function(err) {
  if(err) throw err;
  console.log("volume is now", volume);
});
 
client.on('status', function(status) {
  // Reports the full state of the AVTransport service the first time it fires,
  // then reports diffs. Can be used to maintain a reliable copy of the
  // service internal state.
  console.log(status);
});
 
client.on('loading', function() {
  console.log('loading');
});
 
client.on('playing', function() {
  console.log('playing');
 
  client.getPosition(function(err, position) {
    console.log(position); // Current position in seconds
  });
 
  client.getDuration(function(err, duration) {
    console.log(duration); // Media duration in seconds
  });
});
 
client.on('paused', function() {
  console.log('paused');
});
 
client.on('stopped', function() {
  console.log('stopped');
});
 
client.on('speedChanged', function(speed) {
  // Fired when the user rewinds of fast-forwards the media from the remote
  console.log('speedChanged', speed);
});
