multimedia.js

A toolkit and collection library for all things multimedia in JavaScript. Pipelines processing units using Node-like streams.

It is intended for use in Node (desktop/server) as well as in the browser. There are distributions for all commonly known package standards (AMD/UMD/CJS/2) or global namespace.

An Example

"Mux' an MP3 into MP4 from a file into a file"

Note that we could now exchange the word "file" by anything else like some sort of player, decoder, transcoder, some kind of processing, WebAudio, a MediaSource, an HTTP request ...

  var mm = require('multimedia');
  // Create some pipeline elements
  var src = new mm.Units.File.Src('somefile.mp3'),
  	parser = new mm.Units.MP3Parser(),
  	muxer = new mm.Units.MP4Mux(UnitMP4Mux.Profiles.MP3_AUDIO_ONLY),
  	sink = new mm.Units.File.Sink('somefile.mp4');
  
  sink.on('finish', function() {
    console.log('received eos signal');
  	done();
  });
  
  src.on('open', function() {
  	console.log('file open');
  	
  	// Link the pipeline elements together
  	FileSrc -> MP3Parser -> MP4Muxer -> FileSink
  	
  	mm.Unit.link(src, parser, muxer, sink);
  	
  });

How to use it on a web page without require

  var mm == window.multimedia;
  </script>

or
