HTML

Player extends upon the standard HTML5 media element markup so that's all you need for those types.

HTML5 Video

<video poster="/path/to/poster.jpg" id="player" playsinline controls>
    <source src="/path/to/video.mp4" type="video/mp4">
    <source src="/path/to/video.webm" type="video/webm">

    <!-- Captions are optional -->
    <track kind="captions" label="English captions" src="/path/to/captions.vtt" srclang="en" default>
</video>

HTML5 Audio

<audio id="player" controls>
    <source src="/path/to/audio.mp3" type="audio/mp3">
    <source src="/path/to/audio.ogg" type="audio/ogg">
</audio>

SVG

The icons used in the Player controls are loaded in an SVG sprite. The sprite is automatically loaded from our CDN by default. If you already have an icon build system in place, you can include the source plyr icons (see /src/sprite for source icons).

Using the iconUrl option

You can however specify your own iconUrl option and Player will determine if the url is absolute and requires loading by AJAX/CORS due to current browser limitations or if it's a relative path, just use the path directly.

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/

Using the inlineSvg option

You can specify inlineSvg option like this:

    const inlineSvg = require('wplayer/dist/plyr.svg');
    
    const player = new Player(someSelector, {
        controls: [
           ...
        ],
        loadSprite: true,
        inlineSvg
    });

Cross Origin (CORS)

You'll notice the crossorigin attribute on the example <video> elements. This is because the TextTrack captions are loaded from another domain. If your TextTrack captions are also hosted on another domain, you will need to add this attribute and make sure your host has the correct headers setup. For more info on CORS checkout the MDN docs: 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

Initialising

You can specify a range of arguments for the constructor to use:

Note: If a NodeList, Array, or jQuery object are passed, the first element will be used for setup. To setup multiple players, see setting up multiple players below.

Here's some examples

Passing a string selector:

const player = new Player('#player');

Passing a HTMLElement:

const player = new Player(document.getElementById('player'));

Passing a NodeList (see note below):

const player = new Player(document.querySelectorAll('.js-player'));

The NodeList, HTMLElement or string selector can be the target <video>, <audio>, or <div> wrapper for embeds.

Setting up multiple players

You have two choices here. You can either use a simple array loop to map the constructor:

const players = Array.from(document.querySelectorAll('.js-player')).map(p => new Player(p));

...or use a static method where you can pass a string selector, a NodeList or an Array of elements:

const players = Player.setup('.js-player');

Both options will also return an array of instances in the order of they were in the DOM for the string selector or the source NodeList or Array.

Passing options

The second argument for the constructor is the options object:

const player = new Player('#player', {
    /* options */
});

In all cases, the constructor will return a Player object that can be used with the API methods. See the API section for more info.

Options

Options can be passed as an object to the constructor as above or as JSON in data-plyr-config attribute on each of your target elements:

<video src="/path/to/video.mp4" id="player" controls data-plyr-config='{ "title": "This is an example video", "volume": 1, "debug": true }'></video>

Note the single quotes encapsulating the JSON and double quotes on the object keys. Only string values need double quotes.

Option Type Default Description
enabled Boolean true Completely disable Player. This would allow you to do a User Agent check or similar to programmatically enable or disable Player for a certain UA. Example below.
debug Boolean false Display debugging information in the console
controls Array, Function or Element ['play-large', 'play', 'progress', 'current-time', 'mute', 'volume', 'captions', 'settings', 'pip', 'airplay', 'fullscreen'] If a function is passed, it is assumed your method will return either an element or HTML string for the controls. Three arguments will be passed to your function; id (the unique id for the player), seektime (the seektime step in seconds), and title (the media title). See controls.md for more info on how the html needs to be structured.
settings Array ['captions', 'quality', 'speed', 'loop'] If you're using the default controls are used then you can specify which settings to show in the menu
i18n Object See defaults.js Used for internationalization (i18n) of the text within the UI.
loadSprite Boolean true Load the SVG sprite specified as the iconUrl option (if a URL). If false, it is assumed you are handling sprite loading yourself.
iconUrl String null Specify a URL or path to the SVG sprite. See the SVG section for more info.
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 sprite but with the default controls. Most people can ignore this option.
blankVideo String https://cdn.plyr.io/static/blank.mp4 Specify a URL or path to a blank video file used to properly cancel network requests.
autoplay Boolean false Autoplay the media on load. This is generally advised against on UX grounds. It is also disabled by default in some browsers. If the autoplay attribute is present on a <video> or <audio> element, this will be automatically set to true.
autopause¹ Boolean true Only allow one player playing at once.
seekTime Number 10 The time, in seconds, to seek when a user hits fast forward or rewind.
volume Number 1 A number, between 0 and 1, representing the initial volume of the player.
muted Boolean false Whether to start playback muted. If the muted attribute is present on a <video> or <audio> element, this will be automatically set to true.
clickToPlay Boolean true Click (or tap) of the video container will toggle play/pause.
disableContextMenu Boolean true Disable right click menu on video to help as very primitive obfuscation to prevent downloads of content.
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.
resetOnEnd Boolean false Reset the playback to the start once playback is complete.
keyboard Object { focused: true, global: false } Enable keyboard shortcuts for focused players only or globally
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 for media.
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).
invertTime Boolean true Display the current time as a countdown rather than an incremental counter.
toggleInvert Boolean true Allow users to click to toggle the above.
listeners Object null Allows binding of event listeners to the controls before the default handlers. See the defaults.js for available listeners. If your handler prevents default on the event (event.preventDefault()), the default handler will not fire.
captions Object { active: false, language: 'auto', update: false } active: Toggles if captions should be active by default. language: Sets the default language to load (if available). 'auto' uses the browser language. update: Listen to changes to tracks and update menu. This is needed for some streaming libraries, but can result in unselectable language options).
fullscreen Object { enabled: true, fallback: true, iosNative: false } enabled: Toggles whether fullscreen should be enabled. fallback: Allow fallback to a full-window solution. iosNative: whether to use native iOS fullscreen when entering fullscreen (no custom controls)
ratio String 16:9 The aspect ratio you want to use for embedded players.
storage Object { enabled: true, key: 'plyr' } enabled: Allow use of local storage to store user settings. key: The key name to use.
speed Object { selected: 1, options: [0.5, 0.75, 1, 1.25, 1.5, 1.75, 2] } selected: The default speed for playback. options: Options to display in the menu. Most browsers will refuse to play slower than 0.5.
quality Object { default: 'default', options: ['hd2160', 'hd1440', 'hd1080', 'hd720', 'large', 'medium', 'small', 'tiny', 'default'] } Currently only supported by YouTube. default is the default quality level, determined by YouTube. options are the options to display.
loop Object { active: false } active: Whether to loop the current video. If the loop attribute is present on a <video> or <audio> element, this will be automatically set to true This is an object to support future functionality.
ads Object { enabled: false, publisherId: '' } enabled: Whether to enable vi.ai ads. publisherId: Your unique vi.ai publisher ID.
urls Object See source. If you wish to override any API URLs then you can do so here. You can also set a custom download URL for the download button.
  1. Vimeo only

API

There are methods, setters and getters on a Player object.

Object

The easiest way to access the Player object is to set the return value from your call to the constructor to a variable. For example:

const player = new Player('#player', {
    /* options */
});

You can also access the object through any events:

element.addEventListener('ready', event => {
    const player = event.detail.plyr;
});

Methods

Example method use:

player.play(); // Start playback
player.fullscreen.enter(); // Enter fullscreen
Method Parameters Description
play()¹ - Start playback.
pause() - Pause playback.
togglePlay(toggle) Boolean Toggle playback, if no parameters are passed, it will toggle based on current status.
stop() - Stop playback and reset to start.
restart() - Restart playback.
rewind(seekTime) Number Rewind playback by the specified seek time. If no parameter is passed, the default seek time will be used.
forward(seekTime) Number Fast forward by the specified seek time. If no parameter is passed, the default seek time will be used.
increaseVolume(step) Number Increase volume by the specified step. If no parameter is passed, the default step will be used.
decreaseVolume(step) Number Increase volume by the specified step. If no parameter is passed, the default step will be used.
toggleCaptions(toggle) Boolean Toggle captions display. If no parameter is passed, it will toggle based on current status.
fullscreen.enter() - Enter fullscreen. If fullscreen is not supported, a fallback "full window/viewport" is used instead.
fullscreen.exit() - Exit fullscreen.

  1. YouTube only. HTML5 will follow.
  2. HTML5 only

The .source setter

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

Video example:

player.source = {
    type: 'video',
    title: 'Example title',
    sources: [
        {
            src: '/path/to/movie.mp4',
            type: 'video/mp4',
            size: 720,
        },
        {
            src: '/path/to/movie.webm',
            type: 'video/webm',
            size: 1080,
        },
    ],
    poster: '/path/to/poster.jpg',
    tracks: [
        {
            kind: 'captions',
            label: 'English',
            srclang: 'en',
            src: '/path/to/captions.en.vtt',
            default: true,
        },
        {
            kind: 'captions',
            label: 'French',
            srclang: 'fr',
            src: '/path/to/captions.fr.vtt',
        },
    ],
};

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',
        },
    ],
};

Note: src property for YouTube and Vimeo can either be the video ID or the whole URL.

Property Type Description
type String Either video or audio. Note: YouTube and Vimeo are currently not supported as audio sources.
title String Optional. Title of the new media. Used for the aria-label attribute on the play button, and outer container. YouTube and Vimeo are populated automatically.
sources Array This is an array of sources. For HTML5 media, the properties of this object are mapped directly to HTML attributes so more can be added to the object if required.
poster¹ String The URL for the poster image (HTML5 video only).
tracks¹ String 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 <track kind="captions" label="English" srclang="en" src="https://cdn.selz.com/plyr/1.0/example_captions_en.vtt" default> and similar for the French version. Booleans are converted to HTML5 value-less attributes.
  1. HTML5 only

Events

You can listen for events on the target element you setup Player on (see example under the table). Some events only apply to HTML5 audio and video. Using your reference to the instance, you can use the on() API method or addEventListener(). Access to the API can be obtained this way through the event.detail.plyr property. Here's an example:

player.on('ready', event => {
    const instance = event.detail.plyr;
});

Standard Media Events

Event Type Description
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.
playing Sent when the media begins to play (either for the first time, after having been paused, or after ending and then restarting).
play Sent when playback of the media starts after having been paused; that is, when playback is resumed after a prior pause event.
pause Sent when playback is paused.
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 state is changed).
seeking Sent when a seek operation begins.
seeked Sent when a seek operation completes.
ratechange Sent when the playback speed changes.
ended Sent when playback completes. Note: This does not fire if autoplay is true.
enterfullscreen Sent when the player enters fullscreen mode (either the proper fullscreen or full-window fallback for older browsers).
exitfullscreen Sent when the player exits fullscreen mode.
captionsenabled Sent when captions are enabled.
captionsdisabled Sent when captions are disabled.
languagechange Sent when the caption language is changed.
controlshidden Sent when the controls are hidden.
controlsshown Sent when the controls are shown.
ready Triggered when the instance is ready for API calls.

HTML5 only

Event Type Description
loadstart Sent when loading of the media begins.
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.
qualitychange The quality of playback has changed.
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.
stalled Sent when the user agent is trying to fetch media data, but data is unexpectedly not forthcoming.
waiting Sent when the requested operation (such as playback) is delayed pending the completion of another operation (such as a seek).
emptied he 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.
cuechange Sent when a TextTrack has changed the currently displaying cues.
error Sent when an error occurs. The element's error attribute contains more information.

Shortcuts

By default, a player will bind the following keyboard shortcuts when it has focus. If you have the global option to true and there's only one player in the document then the shortcuts will work when any element has focus, apart from an element that requires input.

Key Action
0 to 9 Seek from 0 to 90% respectively
space Toggle playback
K Toggle playback
Seek backward by the seekTime option
Seek forward by the seekTime option
Increase volume
Decrease volume
M Toggle mute
F Toggle fullscreen
C Toggle captions
L Toggle loop

Fullscreen

Fullscreen in Player is supported by all browsers that currently support it.

Browser support

Player supports the last 2 versions of most modern browsers.

Browser Supported
Safari
Mobile Safari ✓¹
Firefox
Chrome
Opera
Edge
IE11 ✓³
IE10 ✓²³
  1. Mobile Safari on the iPhone forces the native player for <video> unless the playsinline attribute is present. Volume controls are also disabled as they are handled device wide.
  2. Native player used (no support for <progress> or <input type="range">) but the API is supported. No native fullscreen support, fallback can be used (see options).
  3. Polyfills required. See below.

Polyfills

Player uses ES6 which isn't supported in all browsers quite yet. This means some features will need to be polyfilled to be available otherwise you'll run into issues. We've elected to not burden the ~90% of users that do support these features with extra JS and instead leave polyfilling to you to work out based on your needs. The easiest method I've found is to use polyfill.io which provides polyfills based on user agent. This is the method the demo uses.

Checking for support

You can use the static method to check for support. For example

const supported = Player.supported('video', 'html5', true);

The arguments are:

  • Media type (audio or video)
  • Provider (html5, youtube or vimeo)
  • Whether the player has the playsinline attribute (only applicable to iOS 10+)

Disable support programatically

The enabled option can be used to disable certain User Agents. For example, if you don't want to use Player 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.

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.

Issues

If you find anything weird with Player, please let us know using the GitHub issues tracker.
