Image of Plyr

Why?

We wanted a lightweight, accessible and customizable media player that supports modern browsers. Sure, there are many other players out there but we wanted to keep things simple, using the right elements for the job.

Features

  • Accessible - full support for VTT captions and screen readers
  • Lightweight - under 10KB minified and gzipped
  • Customisable - make the player look how you want with the markup you want
  • Semantic - uses the right elements. <input type="range"> for volume and <progress> for progress and well, <button>s for buttons. There's no <span> or <a href="#"> button hacks
  • Responsive - as you'd expect these days
  • HTML Video & Audio - support for both formats
  • Embedded Video - support for YouTube and Vimeo video playback
  • API - toggle playback, volume, seeking, and more
  • Universal events - no messing around with Vimeo and YouTube APIs, all events are universal across formats
  • Fullscreen - supports native fullscreen with fallback to "full window" modes
  • i18n support - support for internationalization of controls
  • No dependencies - written in "vanilla" JavaScript, no jQuery required

Oh and yes, it works with Bootstrap.

If you have any cool ideas or features, please let me know by creating an issue or, of course, forking and sending a pull request.

Implementation

Check docs/index.html and docs/dist/docs.js for an example setup.

Heads up: the example index.html file needs to be served from a webserver (such as Apache, Nginx, IIS or similar) unless you change the file sources to include http or https. e.g. change //cdn.plyr.io/1.6.11/plyr.js to https://cdn.plyr.io/1.6.11/plyr.js

Node Package Manager (NPM)

Using NPM, you can grab Plyr:

npm install plyr

https://www.npmjs.com/package/plyr

Bower

If bower is your thang, you can grab Plyr using:

bower install plyr

http://bower.io/search/?q=plyr

More info on setting up dependencies can be found in the Bower Docs

Ember

The awesome @louisrudner has created an ember component, available by running:

ember addon:install ember-cli-plyr

More info is on npm and GitHub

CDN

If you want to use our CDN, you can use the following:

<link rel="stylesheet" href="https://cdn.plyr.io/1.6.11/plyr.css">
<script src="https://cdn.plyr.io/1.6.11/plyr.js"></script>

The SVG sprite/defs file can be found here: https://cdn.plyr.io/1.6.11/plyr.svg.

CSS & Styling

If you want to use the default css, add the plyr.css file from /dist into your head, or even better use plyr.less or plyr.scss file included in /src in your build to save a request.

<link rel="stylesheet" href="dist/plyr.css">

The default setup uses the BEM methodology with plyr as the block, e.g. .plyr__controls. You can change the class hooks in the options. Check out the source for more on this.

SVG

The SVG sprite for the controls icons can be loaded two ways:

  • By passing the relative path to the sprite as the iconUrl option; or
  • Using AJAX, injecting the sprite into a hidden div.

Using the iconUrl option

This method requires the SVG sprite to be hosted on the same domain as your page hosting the player. Currently no browser supports cross origin SVG sprites due to XSS issues. Fingers crossed this will come soon though. An example value for this option would be:

/path/to/plyr.svg

Using AJAX

Using AJAX means you can load the sprite from a different origin. Avoiding the issues above. This is an example script to load an SVG sprite best added before the closing </body>, before any other scripts.

<script>
(function(d, p){
    var a = new XMLHttpRequest(),
        b = d.body;
    a.open('GET', p, true);
    a.send();
    a.onload = function() {
        var c = d.createElement('div');
        c.setAttribute('hidden', '');
        c.innerHTML = a.responseText;
        b.insertBefore(c, b.childNodes[0]);
    };
})(document, 'https://cdn.plyr.io/1.6.11/plyr.svg');
</script>

If you're using the <base> tag on your site, you may need to use something like this: svgfixer.js

More info on SVG sprites here: http://css-tricks.com/svg-sprites-use-better-icon-fonts/ and the AJAX technique here: http://css-tricks.com/ajaxing-svg-sprite/

HTML

The only extra markup that's needed to use plyr is a <div> wrapper. Replace the source, poster and captions with urls for your media.

<div class="plyr">
    <video poster="/path/to/poster.jpg" controls>
        <!-- Video files -->
        <source src="/path/to/video.mp4" type="video/mp4">
        <source src="/path/to/video.webm" type="video/webm">

        <!-- Text track file -->
        <track kind="captions" label="English captions" src="/path/to/captions.vtt" srclang="en" default>

        <!-- Fallback for browsers that don't support the <video> element -->
        <a href="/path/to/movie.mp4">Download</a>
    </video>
</div>

And the same for <audio>

<div class="plyr">
    <audio controls>
        <!-- Audio files -->
        <source src="/path/to/audio.mp3" type="audio/mp3">
        <source src="/path/to/audio.ogg" type="audio/ogg">

        <!-- Fallback for browsers that don't support the <audio> element -->
        <a href="/path/to/audio.mp3">Download</a>
    </audio>
</div>

For YouTube and Vimeo, Plyr uses the standard YouTube API markup (an empty <div>):

<div class="plyr">
    <div data-video-id="bTqVqk7FSmY" data-type="youtube"></div>
</div>
<div class="plyr">
    <div data-video-id="143418951" data-type="vimeo"></div>
</div>

Cross Origin (CORS)

You'll notice the crossorigin attribute on the example <video> and <audio> elements. This is because the media is loaded from another domain. If your media is hosted on another domain, you may need to add this attribute.

More info on CORS here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS

Captions

WebVTT captions are supported. To add a caption track, check the HTML example above and look for the <track> element.

Be sure to validate your caption files

JavaScript

Quick setup

Here's an example of a default setup:

<script src="https://cdn.plyr.io/1.6.11/plyr.js"></script>
<script>plyr.setup();</script>

This will look for all elements with the specified container classname (default is plyr) and setup plyr on each element found. You can specify other options, including a different selector hook below. The container classname will be added to the specified element(s) if it is not already present (for the CSS).

You can initialize the player a few other ways:

Passing a NodeList:

plyr.setup(document.querySelectorAll('.js-plyr'), options);

Passing a HTMLElement:

plyr.setup(document.querySelector('.js-plyr'), options);

Passing a string selector:

plyr.setup('.js-plyr', options);

Passing just the options object:

plyr.setup(options);

RangeTouch

Some touch browsers (particularly Mobile Safari on iOS) seem to have issues with <input type="range"> elements whereby touching the track to set the value doesn't work and sliding the thumb can be tricky. To combat this, I've created RangeTouch which I'd recommend including in your solution. It's a tiny script with a nice benefit for users on touch devices.

Options

Options must be passed as an object to the setup() method as above or as JSON in data-plyr attribute on each of your target elements (e.g. data-plyr='{ title: "testing" }') - note the single quotes encapsulating the JSON.

Option Type Default Description
enabled Boolean true Completely disable Plyr. This would allow you to do a User Agent check or similar to programmatically enable or disable Plyr for a certain UA. Example below.
html String See controls.md See controls.md for more info on how the html needs to be structured.
controls Array ['play-large', 'play', 'progress', 'current-time', 'mute', 'volume', 'captions', 'fullscreen'] Toggle which control elements you would like to display when using the default controls html. If you specify a html option, this is redundant. The default value is to display everything.
i18n Object See controls.md Used for internationalization (i18n) of the tooltips/labels within the buttons.
iconPrefix String plyr Specify the id prefix for the icons used in the default controls (e.g. "plyr-play" would be "plyr"). This is to prevent clashes if you're using your own SVG defs file but with the default controls. Most people can ignore this option.
iconUrl String null Specify a relative path to the SVG sprite, hosted on the *same domain* as the page the player is hosted on. Using this menthod means no requirement for the AJAX sprite loading script. See the SVG section for more info.
debug Boolean false Display debugging information on what Plyr is doing.
autoplay Boolean false Autoplay the media on load. This is generally advised against on UX grounds. It is also disabled on iOS (an Apple limitation).
seekTime Number 10 The time, in seconds, to seek when a user hits fast forward or rewind.
volume Number 5 A number, between 1 and 10, representing the initial volume of the player.
clickToPlay Boolean true Click (or tap) of the video container will toggle pause/play.
hideControls Boolean true Hide video controls automatically after 2s of no mouse or focus movement, on control element blur (tab out), on playback start or entering fullscreen. As soon as the mouse is moved, a control element is focused or playback is paused, the controls reappear instantly.
showPosterOnEnd Boolean false This will restore and *reload* HTML5 video once playback is complete. Note: depending on the browser caching, this may result in the video downloading again (or parts of it). Use with caution.
tooltips Object { controls: false, seek: true } controls: Display control labels as tooltips on :hover & :focus (by default, the labels are screen reader only).

seek: Display a seek tooltip to indicate on click where the media would seek to.
duration Number null Specify a custom duration.
displayDuration Boolean true Displays the duration of the media on the "metadataloaded" event (on startup) in the current time display. This will only work if the `preload` attribute is not set to `none` (or is not set at all) and you choose not to display the duration (see controls option).
selectors Object See plyr.js in /src for more info. You probably don't need to change any of these.
listeners Object Allows early binding of event listeners to the controls. See controls above for list of controls and see plyr.js in /src for more info.
classes Object Similar to above, these are the classes added to the player when state changes occur.
captions Object One property defaultActive which toggles if captions should be on by default. The default value is false.
fullscreen Object See below
storage Object Two properties; enabled which toggles if local storage should be enabled (if the browser supports it). The default value is `true`. This enables storing user settings, currently it only stores volume but more will be added later. The second property key is the key used for the local storage. The default is plyr_volume until more settings are stored.

Fullscreen options

Option Type Default Description
enabled Boolean true Toggles if fullscreen should be enabled (if the browser supports it).
fallback Boolean true Enable a full viewport view for older browsers.
allowAudio Boolean false Allow audio play to toggle fullscreen. This will be more useful later when posters are supported.

API

Fetching the plyr instance

A plyr object is added to any element that Plyr is initialized on. You can then control the player by accessing methods in the plyr object.

There are two ways to access the instance, firstly you re-query the element container you used for setup (e.g. .js-plyr) like so:

var player = document.querySelector('.js-plyr').plyr;

Or you can use the returned object from your call to the setup method:

var player = plyr.setup('.js-plyr')[0];

This will return an array of plyr instances setup, so you need to specify the index of the instance you want. This is less useful if you are setting up mutliple instances. You can listen for the setup event documented below which will return each instance one by one, as they are setup (in the plyr key of the event object).

Once you have your instance, you can use the API methods below on it. For example to pause it:

player.pause();

Here's a list of the methods supported:

Method Parameters Description
play() Plays the media
pause() Pauses the media
restart() Restarts playback
rewind(...) Number Rewinds by the provided parameter, in seconds. If no parameter is provided, the default seekInterval is used (10 seconds).
forward(...) Number Fast forwards by the provided parameter, in seconds. If no parameter is provided, the default seekInterval is used (10 seconds).
seek(...) Number Seeks the media to the provided parameter, time in seconds.
setVolume(...) Number Sets the player volume to the provided parameter. The value should be between 0 (muted) and 10 (loudest). If no parameter is provided, the default volume is used (5). Values over 10 are ignored.
togglePlay() Boolean Toggles playback for the player based on either the boolean argument or it's current state.
toggleMute() Toggles mute for the player.
toggleCaptions() Toggles whether captions are enabled.
toggleFullscreen() Event Toggles fullscreen. This can only be initiated by a user gesture due to browser security, i.e. a user event such as click.
isFullscreen() Boolean returned if the player is in fullscreen.
support(...) String Determine if a player supports a certain MIME type. This is not supported for embedded content (YouTube).
source(...) Object or undefined Get/Set the media source.

Object
See below

YouTube
Currently this API method only accepts a YouTube ID when used with a YouTube player. I will add URL support soon, along with being able to swap between types (e.g. YouTube to Audio or Video and vice versa.)

undefined
Returns the current media source url. Works for both native videos and embeds.
poster(...) String Set the poster url. This is supported for the video element only.
destroy() Destroys the plyr UI and any media event listeners, effectively restoring to the previous state before setup() was called.
restore() Reverses the effects of the destroy() method, restoring the UI and listeners.

.source() method

This allows changing the plyr source and type on the fly.

Video example:

player.source({
  type:       'video',
  title:      'Example title',
  sources: [{
      src:    '/path/to/movie.mp4',
      type:   'video/mp4'
  },
  {
      src:    '/path/to/movie.webm',
      type:   'video/webm'
  }],
  poster:     '/path/to/poster.jpg',
  tracks:     [{
      kind:   'captions',
      label:  'English',
      srclang:'en',
      src:    '/path/to/captions.vtt',
      default: true
  }]
});

Audio example:

player.source({
  type:       'audio',
  title:      'Example title',
  sources: [{
    src:      '/path/to/audio.mp3',
    type:     'audio/mp3'
  },
  {
    src:      '/path/to/audio.ogg',
    type:     'audio/ogg'
  }]
});

YouTube example:

player.source({
  type:       'video',
  title:      'Example title',
  sources: [{
      src:    'bTqVqk7FSmY',
      type:   'youtube'
  }]
});

Vimeo example

player.source({
  type:       'video',
  title:      'Example title',
  sources: [{
      src:    '143418951',
      type:   'vimeo'
  }]
});

Some more details on the object parameters

Key Type Description
type String Options are video, audio, youtube and vimeo
title String Title of the new media. Used for the aria labelling.
sources Array This is an array of sources. type is optional for YouTube and Vimeo when specifying an array. For YouTube and Vimeo media, only the video ID must be passed as the source as shown above. The keys of this object are mapped directly to HTML attributes so more can be added to the object if required.
poster String URL for the poster image (video only).
tracks Array An array of track objects. Each element in the array is mapped directly to a track element and any keys mapped directly to HTML attributes so as in the example above, it will render as ``. Booleans are converted to HTML5 value-less attributes.

Events

You can listen for events on the element you setup Plyr on. Some events only apply to HTML5 audio and video.

Event name HTML5 only Description
canplay Sent when enough data is available that the media can be played, at least for a couple of frames. This corresponds to the HAVE_ENOUGH_DATA readyState.
canplaythrough Sent when the ready state changes to CAN_PLAY_THROUGH, indicating that the entire media can be played without interruption, assuming the download rate remains at least at the current level. Note: Manually setting the currentTime will eventually fire a canplaythrough event in firefox. Other browsers might not fire this event.
emptied The media has become empty; for example, this event is sent if the media has already been loaded (or partially loaded), and the load() method is called to reload it.
ended Sent when playback completes.
error Sent when an error occurs.  The element's error attribute contains more information.
loadeddata The first frame of the media has finished loading.
loadedmetadata The media's metadata has finished loading; all attributes now contain as much useful information as they're going to.
loadstart Sent when loading of the media begins.
pause Sent when playback is paused.
play Sent when playback of the media starts after having been paused; that is, when playback is resumed after a prior pause event.
playing Sent when the media begins to play (either for the first time, after having been paused, or after ending and then restarting).
progress Sent periodically to inform interested parties of progress downloading the media. Information about the current amount of the media that has been downloaded is available in the media element's buffered attribute.
seeked Sent when a seek operation completes.
seeking Sent when a seek operation begins.
stalled Sent when the user agent is trying to fetch media data, but data is unexpectedly not forthcoming.
timeupdate The time indicated by the element's currentTime attribute has changed.
volumechange Sent when the audio volume changes (both when the volume is set and when the muted attribute is changed).
waiting Sent when the requested operation (such as playback) is delayed pending the completion of another operation (such as a seek).
enterfullscreen User enters fullscreen (either the proper fullscreen or full-window fallback for older browsers)
exitfullscreen User exits fullscreen
captionsenabled Captions toggled on
captionsdisabled Captions toggled off
ready Triggered when initial setup is done or a source change has occurred.

Details borrowed from: https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Media_events

Here's an example of binding an event listener:

document.querySelector('.js-plyr').addEventListener('ready', function() {
    var player = event.target.plyr;
});

Embeds

YouTube and Vimeo are currently supported and function much like a HTML5 video. Check the relevant documentation sections for any differences.

Plyr references a custom version of the Vimeo Froogaloop API as Vimeo have neglected to maintain the library and there were bugs with their version. You don't need to worry about including your own versions of the Vimeo or YouTube JavaScript APIs.

The native API's can be accessed through the embed property of the plyr object. For example:

document.querySelector('.js-plyr').addEventListener('ready', function() {
    var player = event.target.plyr;

    // YouTube
    console.log(player.embed.getVideoData());

    // Vimeo
    console.log(player.embed.api('getColor'));
});

More info on the respective API's here: YouTube API Reference Vimeo API Reference

Please note: not all API methods may work 100%. Your mileage may vary. It's better to use the universal plyr API where possible.

Fullscreen

Fullscreen in Plyr is supported for all browsers that currently support it. If you're using the default CSS, you can also use a "full browser" mode which will use the full browser window by adding the plyr-fullscreen class to your container.

Browser support

Safari Firefox Chrome Opera IE9 IE10+
✔¹ API² ✔³

¹ Mobile Safari on the iPhone forces the native player for <video> so no useful customisation is possible. <audio> elements have volume controls disabled.

² Native player used (no support for <progress> or <input type="range">) but the API is supported (v1.0.28+)

³ IE10 has no native fullscreen support, fallback can be used (see options)

The enabled option can be used to disable certain User Agents. For example, if you don't want to use Plyr for smartphones, you could use:

enabled: /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)

If a User Agent is disabled but supports <video> and <audio> natively, it will use the native player.

Any unsupported browsers will display links to download the media if the correct html is used.

Checking for support

There's an API method for checking support. You can call plyr.supported() and optionally pass a type to it, e.g. plyr.supported("video"). It will return an object with two keys; basic meaning there's basic support for that media type (or both if no type is passed) and full meaning there's full support for plyr.
