vjs.Player

EXTENDS: vjs.Component
DEFINED IN: 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.

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.

<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 Video('example_video_1').

Add a CSS class name to the component's element

PARAMETERS:
  • classToAdd String Classname to add
RETURNS:
  • vjs.Component

inherited from: src/js/component.js#L632

buffered()

Get a TimeRange object with the times of the video that have been downloaded

If you just want the percent of the video that's been downloaded, use bufferedPercent.

// Number of different ranges of time have been buffered. Usually 1.
numberOfRanges = bufferedTimeRange.length,

// Time in seconds when the first range starts. Usually 0.
firstRangeStart = bufferedTimeRange.start(0),

// Time in seconds when the first range ends
firstRangeEnd = bufferedTimeRange.end(0),

// Length in seconds of the first time range
firstRangeLength = firstRangeEnd - firstRangeStart;

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.

getChild( name )

Returns a child component with the provided name

PARAMETERS:
  • name
RETURNS:
  • vjs.Component

inherited from: src/js/component.js#L315

RETURNS:
  • vjs.Component This component, when setting the height
  • Number|String The height, when getting

  }
}

inherited from: src/js/component.js#L443

isFullScreen( [isFS] )

Check if the player is in fullscreen mode

// get
var fullscreenOrNot = myPlayer.isFullScreen();

// set
myPlayer.isFullScreen(true); // tell the player it's in fullscreen

NOTE: As of the latest HTML5 spec, isFullScreen is no longer an official property and instead document.fullscreenElement is used. But isFullScreen is still a valuable property for internal player workings.

PARAMETERS:
  • isFS Boolean (OPTIONAL) Update the player's fullscreen state
RETURNS:
  • Boolean true if fullscreen, false if not
  • vjs.Player self, when setting

defined in: src/js/player.js#L840

PARAMETERS:
  • type String The event type e.g. 'click'
  • fn Function The event listener
RETURNS:
  • vjs.Component self

inherited from: src/js/component.js#L500

PARAMETERS:
  • type String Event type
  • fn Function Event listener
RETURNS:
  • vjs.Component

inherited from: src/js/component.js#L526

options( obj )

Deep merge of options objects

Whenever a property is an object on both options objects the two properties will be merged using vjs.obj.deepMerge.

This is used for merging options for child components. We want it to be easy to override individual options on a child component without having to rewrite all the other default options.

Parent.prototype.options_ = {
  children: {
    'childOne': { 'foo': 'bar', 'asdf': 'fdsa' },
    'childTwo': {},
    'childThree': {}
  }
}
newOptions = {
  children: {
    'childOne': { 'foo': 'baz', 'abc': '123' }
    'childTwo': null,
    'childFour': {}
  }
}

this.options(newOptions);

RESULT

{
  children: {
    'childOne': { 'foo': 'baz', 'asdf': 'fdsa', 'abc': '123' },
    'childTwo': null, // Disabled. Won't be initialized.
    'childThree': {},
    'childFour': {}
  }
}

inherited from: src/js/component.js#L643

requestFullScreen()

Increase the size of the video to full screen

myPlayer.requestFullScreen();

In some browsers, full screen is not supported natively, so it enters "full window mode", where the video fills the browser window. In browsers and devices that support native full screen, sometimes the browser's default controls will be shown, and not the Video.js custom skin. This includes most mobile devices (iOS, Android) and older versions of Safari.

  • vjs.Player self

defined in: src/js/player.js#L862

show()

Show the component element if hidden

RETURNS:
  • vjs.Component

inherited from: src/js/component.js#L653

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 the current playback technology (HTML5/Flash) can support the source you provide. Currently only MP4 files can be used in both HTML5 and Flash.

myPlayer.src("http://www.example.com/path/to/video.mp4");

Source Object (or element): A javascript object containing information about the source file. Use this method if you want the player to determine if it can support the file using the type information.

myPlayer.src({ type: "video/mp4", src: "http://www.example.com/path/to/video.mp4" });

Array of Source Objects: To provide multiple versions of the source so that it can be played using HTML5 across browsers you can use an array of source objects. Video.js will detect which version is supported and load that file.

myPlayer.src([
  { type: "video/mp4", src: "http://www.example.com/path/to/video.mp4" },
  { type: "video/webm", src: "http://www.example.com/path/to/video.webm" },
  { type: "video/ogg", src: "http://www.example.com/path/to/video.ogv" }
]);

PARAMETERS:
  • percentAsDecimal Number The new volume as a decimal percent
RETURNS:
  • Number The current volume, when getting
  • vjs.Player self, when setting

defined in: src/js/player.js#L772

width( [num], skipListeners )

Set or get the width of the component (CSS values)

Setting the video tag dimension values only works with values in pixels. Percent values will not work. Some percents can be used, but width()/height() will return the number + %, not the actual computed width/height.
