# vjs.Player

__EXTENDS__: [vjs.Component](vjs.Component.md)  
__DEFINED IN__: [src/js/player.js#L21](https://github.com/videojs/video.js/blob/master/src/js/player.js#L21)  

An instance of the `vjs.Player` class is created when any of the Video.js setup methods are used to initialize a video.

```js
var myPlayer = videojs('example_video_1');
```

In the follwing example, the `data-setup` attribute tells the Video.js library to create a player instance when the library is ready.

```html
<video id="example_video_1" data-setup='{}' controls>
  <source src="my-source.mp4" type="video/mp4">
</video>
```

After an instance has been created it can be accessed globally using `videojs('example_video_1')`.

### enableTouchActivity()
> Report user touch activity when touch events occur
> 
> User activity is used to determine when controls should show/hide. It's
> relatively simple when it comes to mouse events, because any mouse event
> should show the controls. So we capture mouse events that bubble up to the
> player and report activity when that happens.
> 
> With touch events it isn't as easy. We can't rely on touch events at the
> player level, because a tap (touchstart + touchend) on the video itself on
> mobile devices is meant to turn controls off (and on). User activity is
> checked asynchronously, so what could happen is a tap event on the video
> turns the controls off, then the touchend event bubbles up to the player,
> which if it reported user activity, would turn the controls right back on.
> (We also don't want to completely block touch events from bubbling up)
> 
> Also a touchmove, touch+hold, and anything other than a tap is not supposed
> to turn the controls back on on a mobile device.
> 
> Here we're setting the default component behavior to report user activity
> whenever touch events happen, and this can be turned off by components that
> want touch events to act differently.

### src( [source] )
> The source function updates the video source
> 
> There are three types of variables you can pass as the argument.
> 
> **URL String**: A URL to the the video file. Use this method if you are sure

>     myPlayer.src("http://www.example.com/path/to/video.mp4");
> 
> **Source Object (or element):** A javascript object containing information

> it can support the file using the type information.
> 
>     myPlayer.src({ type: "video/mp4", src: "http://www.example.com/path/to/video.mp4" });
>

> source objects. Video.js will detect which version is supported and load that
> file.
