<a id="initialize"></a>
## Initialize player

You can use this as a standalone library if you wish, or just stick with the full MediaElementPlayer.

## Standalone
```html
<script>

    var player = new MediaElement('player', {
    	pluginPath: "/path/to/shims/", 
    	success: function(mediaElement, originalNode) {
            // do things
            
        }
    });

</script>
```

<a id="automatic"></a>
### Automatic start
You can avoid running any startup scripts by adding `class="mejs-player"` to the `<video>` or `<audio>` tag. All the player configuration can be added through `data-mejsoptions` attribute.
```html	
<video src="myvideo.mp4" width="320" height="240" 
		class="mejs-player" 
		data-mejsoptions='{"pluginPath": "/path/to/shims/", "alwaysShowControls": "true"}'></video>
```

<a id="vanilla"></a>
### Vanilla JavaScript
```html
<script>

    var player = new MediaElementPlayer('player', {
    	pluginPath: "/path/to/shims/", 
    	success: function(mediaElement, originalNode) {
	        // do things
        }
    });
    
</script>	
```

<a id="jquery"></a>
### jQuery
```html
<script>

    $('#mediaplayer').mediaelementplayer({
    	pluginPath: "/path/to/shims/", 
    	success: function(mediaElement, originalNode) {
	        // do things
        }
    });

    // To access player after its creation through jQuery use:
    var playerId = $('#mediaplayer').closest('.mejs__container').attr('id');
    // or $('#mediaplayer').closest('.mejs-container').attr('id') in "legacy" stylesheet
    
    var player = mejs.players[playerId];
    
    // With iOS (iPhone), since it defaults always to QuickTime, you access the player directly;
    // i.e., if you wanna exit fullscreen on iPhone using the player, use this:
    var player = $('#mediaplayer')[0];
    player.webkitExitFullScreen();
    
</script>
```

<a id="npm-meteor"></a>
### NPM/Meteor
```javascript
// To import only MediaElement class
import 'mediaelement/standalone';

// To import only MediaElementPlayer class and $.fn.mediaelementplayer plugin 
// (includes the HTML5 and FLahs renderers ONLY)
import 'mediaelement/player';

// To import all the plugin (you will have access to the MediaElement and MediaElementPlayer classes,
// $.fn.mediaelementplayer plugin and all the renderers)
import 'mediaelement/full';
```

**IMPORTANT**: To ensure you can use the `$.fn.mediaelementplayer` plugin, you will need to import jQuery as well in your bundle like follows:

1. Create a `jquery-global.js` file that contains:
```javascript
'use strict';

import jquery from 'jquery';
window.jQuery = jquery;
window.$ = jquery;
```
2. Import the `jquery-global.js` along with the desired package
```javascript
'use strict';

import '/path/to/jquery-global';
import 'mediaelement/all'; // or import `mediaelement/player`;
```

<a id="requirejs"></a>
### RequireJS
With RequireJS, you will need the following setup if you are planning to use HLS, M(PEG)-DASH or FLV, given the way the packages are bundled.

To make it work, install via NPM any of the external libraries you will need (i.e., HLS.js).
```
npm install hls.js
```
In your code, include a `shim` for the external library and then assign the exported variable to the global scope.
```javascript
requirejs.config({
    // Other configuration
    shim: {
    	// Other shims
        'path/to/hls': {deps: ['require'], exports: "Hls"},
    }
});

// Later on the code...
require(['path/to/hls'], function (Hls) {
        window.Hls = Hls;

        require(['path/to/mediaelement-and-player'], function (MediaElementPlayer) {

            var player = new MediaElementPlayer('media-id', {
            	// Player configuration
            });
        });
    });

```

**IMPORTANT NOTE:** To keep Flash shims working you **MUST** setup the path where the shims are via `pluginPath`, and do not forget to add a slash at the end of the string. Please refer to the examples above. In Meteor, the right path to be used is `/packages/johndyer_mediaelement/build/`;

<a id="renderers-usage"></a>
## Use Renderers

By default, all the renderers will be called by their IDs and the plugin will try to detect the best one. 

However, if you need to use just a subset of renderers in a specific order, you must list their IDs using `renderers` option when configuring your player.

```javascript

// Use globally native M(PEG)-DASH renderer first, then Flash shim 
mejs.Renderers.order = ['native_dash', 'flash_dash'];

$('video, audio').mediaelementplayer({
    renderers: ['native_dash', 'flash_dash'], // Use only M(PEG)DASH renderers
    // More configuration
});
```

`MediaElement` can call methods from the current renderer's API (if any) by invoking its own API instance, a special object attached to the `MediaElement` instance. Keep in mind that some methods won't work if they are not bound to an event. An example using native HLS:
```javascript
$('video').mediaelementplayer({
    pluginPath: '../build/',
    // All the config related to HLS
    hls: {
        debug: true,
        autoStartLoad: false
    },
    
    // More configuration parameters...
    
    success: function(media, node) {
    	
    	// Since it could be that the HLS element is not yet loaded, use a `setInterval()` method to check when 
    	// it's ready and then destroy it; this applies to the native renderers (HLS, DASH and FLV)
    	var interval = setInterval(function () {
        
    		// media.hlsPlayer is the instance of HLS.js in MediaElement
    		// each one of the renderers has a player instance
    		// See `Use of Renderers` above for more information
            if (media.rendererName === 'native_hls' && media.hlsPlayer !== undefined) {
            	
            	// clear interval to stop checking if HLS object is available
                clearInterval(interval);
            	
            	media.hlsPlayer.on(Hls.Events.MEDIA_ATTACHED, function() {
            		// All the code when this event is reached...
                    console.log('Media attached!');
                });
                
                // Manifest file was parsed, invoke loading method
                media.hlsPlayer.on('hlsManifestParsed', function() {
            		// All the code when this event is reached...
            		console.log('Manifest parsed!');
            
                });
                
            	media.hlsPlayer.on(Hls.Events.FRAG_PARSING_METADATA, function (event, data) {
            		// All the code when this event is reached...
            		console.log(data);
                });
            }
            
        }, 500); 
    }
});
```

To know how well-supported are each one of the formats, visit http://caniuse.com/


**Notes** 
* Support for `wmv` and `wma` has been dropped since most of the major players are not supporting it as well.
* `ogg` formats will not play consistently in all browsers so it is strongly recommended a MP3 fallback for audio, or MP4 for video.
* `wav` and `webm` formats will only play on Browsers that support it natively since there is currently no Flash fallback to allow them to play in other browsers.
* `flv` and `mpd` will not work on iOS since it doesn't support MSE; for `mpd` use a `m3u8` fallback.


<a id="destroy"></a>
## Destroy player

In order to destroy the player, you must pause the player and then invoke the `remove()` method.
```javascript

var player = new MediaElementPlayer('#player');

// Using jQuery:
// var playerId = $('#mediaplayer').closest('.mejs__container').attr('id');
// var player = mejs.players[playerId];


if (!player.paused) {
        player.pause();	
}

player.remove();

// If you wanna destroy COMPLETELY the player (including also the `video` tag) use the above and also the following:
var videos = document.getElementsByTagName('video');
for( var i = 0, total = videos.length; i < total; i++ ){ 
        videos[i].parentNode.removeChild(videos[i]);
}


// Using jQuery:
// $('video').each(function() {
//         $(this).remove();
// });
```

Same code can be used for `<audio>` elements.
