README.md

omxdirector

Nodejs module providing a simple interface to omxplayer.

Supports multiple files playing and loops. It's capable of seamless loops if omxplayer supports it natively. When omxplayer doesn't support loops, this module handles loops respawning omxplayer process.

This version supports playing remote (HTTP) files and allow users to seek (-/+ 30 seconds).

Usage

Basic usage

var omx = require('omxdirector');
omx.play('video.avi');
omx.play('http://www.server.com/video.mp4');

Multiple files

omx.play(['video.mp4', 'anothervideo.mp4', 'foo.mp4'], {loop: true});

WARNING: at this time, multiple files playing is not supported by official omxplayer. If using with a fork version, you must enable native loop support (see below).

Options

  • audioOutput "local" or "hdmi" as -o omxplayer argument. If not specified or "default" is system default.
  • loop true to enable --loop omxplayer argument. Default is false.
  • osd 'false' to enable '--no-osd' omxplayer argument. Default is 'true.'

WARNING: at this time, loop is not supported by official omxplayer. If using with a fork version, you must enable native loop support.

Example

omx.play('video.mp4', {loop: true}); // enables loop
omx.play('video.mp4', {audioOutput: 'local'}); // analog audio output

Native loop support

If you have a versione of omxplayer supporting native loop with --loop flag, you can enable it by calling:

var omx = require('omxdirector').enableNativeLoop();

Loop fallback

If using with standard omxplayer, a fallback is provided: once a video is finished, another process of omxplayer is launched. It support multiple files and infinite loop. Although this works fine, native support is better because there's no gap between video.

Status

omx.getStatus()

Return an object with current status:

If process is not running:

{ loaded: false }

If process is running:

{
  loaded: true,
  videos: <Array>,    // videos array passed to play(videos, options)
  settings: <Object>,  // default settings or options object passed to play(videos, options)
  playing: <boolean>  // true if not paused, false if paused
}

Video directory

omx.setVideoDir(path);

Set where to look for videos. Useful when all videos are in the same directory.

Instead of this:

omx.play(['/home/pi/videos/foo.mp4', '/home/pi/videos/bar.mp4', '/home/pi/videos/asdasd.mp4']);

It's possible to use this shortcut:

omx.setVideoDir('/home/pi/videos/');
omx.play(['foo.mp4', 'bar.mp4', 'asdasd.mp4']);

Video suffix

omx.setVideoSuffix(suffix);

Set a suffix for videos. Useful when all videos share the same format.

Instead of this:

omx.play(['foo.mp4', 'bar.mp4', 'asdasd.mp4']);

It's possible to use this shortcut:

omx.setVideoSuffix('.mp4');
omx.play(['foo', 'bar', 'asdasd']);

Other methods

omx.pause();     // pause the video
omx.play();      // resume video playing
omx.stop();      // stop video playing and terminate omxplayer process
omx.isLoaded();  // return true if omxprocess is running
omx.isPlaying(); // return true if omxprocess is running and video is not paused
omx.volup();     // Increases the volume one notch
omx.voldown();   // Decreases the volume one notch
omx.backwards(); // Seek by -30 seconds
omx.forwards();  // Seek by +30 seconds

Events

omx.on('load', function(files, options){}); // video successfully loaded (omxprocess starts)
omx.on('play', function(){});  // when successfully started or resumed from pause
omx.on('pause', function(){}); // when successfully paused
omx.on('stop', function(){});  // when successfully stopped (omxplayer process ends)

TODO

  • Emit event when each video start, stop etc...
  • Implement forward/backward.
  • Enable a fallback for loop and multiple files when native support is disabled.
