node-mplayer

A node.js wrapper for MPlayer on Linux. Use it to play music on your sound card!

Usage

First, install the module with (assuming you already installed MPlayer)

npm install node-mplayer

Then, you need to make a new instance of the module. The constructor of the module can take the path of the file to play.

var Mplayer = require('node-mplayer'); 

var player1 = new Mplayer('/home/node/Music/Kalimba.mp3');
var player2 = new Mplayer('http://mysite.com/myfile.mp3');
var player3 = new Mplayer();

Available methods

play

This method will play the file defined when the player object was instanciated or setted with setFile(). This method MUST be called before any other. It can take in parameter an object that contains the volume, the number of times to play the file (see setVolume and setLoop) and an array of additionnal arguments to pass to MPlayer.

player.play();
player.play({volume: 50});
player.play({volume: 50,
            loop: 10});
player.play({additionnalArgs: ['-ao alsa:device=hw']});

checkPlaying

This method indicates if the player is currently playing something.

player.checkPlaying();  //returns true if playing, false if not

stop

This method will stop the played file.

player.stop();

Returns the length of the file in seconds. It needs a callback.

player.getTimeLength(function(length){
    console.log(length);
});

Returns the elapsed play time in seconds. It needs a callback.

player.getTimePosition(function(elapsedTime){
    console.log(elapsedTime);
});

getPercentPosition

Return the elapsed time in percent. It needs a callback.

player.getPercentPosition(function(elapsedPercent){
    console.log(elapsedPercent);
});
