nw-f2cwa-play

Ffmpeg to Canvas and Web Audio media playback for Node WebKit.

You will need ffmpeg to run this. Under Windows place ffmpeg.exe into vendor directory or on any platform pass ffmpeg path to player as option.

var
  Player = require('nw-f2cwa-play').Player,
  player;

player = new Player({
  selector:'#cnv', // selector for canvas to render video
  ffmpegPath: 'ffmpeg' // in case ffmpeg is available on standard path
});

player.openSrc('udp://@239.0.1.2:1234'); // pass stream url (rtp, udp, http ... anything supported by ffmpeg) or file path

// auto start playback
player.on('canplay',function(){
          player.play();
})

player.on('time',function(time){
  // time is current stream time in seconds
});

Seeking for streams allowing seeking (mostly files) is also supported:

1. Use player.openSrc(url,startPos); to start playback from needed pos. startPos expressed in seconds.
2. Use player.seek(seekPos); seekPos is also expressed in seconds.

See sample App.

This is experiment as for now. May produce unexpected results. Only files/streams with audio are supported, audio is also downsampled to mono for simpler processing.
