Uiza Player Web SDK

Uiza Player is a simple, lightweight, accessible and customizable HTML5, media player that supports modern browsers.

Demos

You can try Uiza in Codepen using our minimal templates. For Streaming we also have example integrations with: Hls.js, Dash.js and VOD

Quick setup

HTML

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

Attribute	Value	Description
`autoplay`	autoplay	Specifies that the video will start playing as soon as it is ready
`controls`	controls	Specifies that video controls should be displayed (such as a play/pause button etc).
`src`	URL	Specifies the URL of the video file
`height`	pixels	Sets the height of the video player
`width`	pixels	Sets the width of the video player
`loop`	loop	Specifies that the video will start over again, every time it is finished
`muted`	muted	Specifies that the audio output of the video should be muted
`poster`	URL	Specifies an image to be shown while the video is downloading, or until the user hits the play button
`preload`	auto / metadata / none	Specifies if and how the author thinks the video should be loaded when the page loads

See initialising for more information on advanced setups.

You can use our CDN for the JavaScript. There's 2 versions; one with and one without polyfills. My recommendation would be to manage polyfills seperately as part of your application but to make life easier you can use the polyfilled build.

Customizing HLS buffer

buffer: {
  maxBufferLength: 15
  maxMaxBufferLength: 90
}

maxBufferLength (default: 10 seconds, maximum 30 seconds)

Maximum buffer length in seconds. If buffer length is/become less than this value, a new fragment will be loaded. This is the guaranteed buffer length hls.js will try to reach, regardless of maxBufferSize.

maxMaxBufferLength: (default 60 seconds, maximum 120 seconds) Maximum buffer length in seconds. Hls.js will never exceed this value, even if maxBufferSize is not reached yet.

hls.js tries to buffer up to a maximum number of bytes (6 MB by default) rather than to buffer up to a maximum nb of seconds. this is to mimic the browser behaviour (the buffer eviction algorithm is starting after the browser detects that video buffer size reaches a limit in bytes)

You can set them in your CSS for all players:

:root {
  --uiza-color-main: #1ac266;
}

...or for a specific class name:

.player {
  --uiza-color-main: #1ac266;
}

...or in your HTML:

<video class="player" style="--uiza-color-main: #1ac266;">
    ...
</vieo>

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 multiple players below.

Single player

Passing a CSS string selector that's compatible with querySelector:

const player = new Uiza('#playerUz');

Passing a HTMLElement:

const player = new Uiza(document.getElementById('playerUz'));

const player = new Uiza(document.querySelector('.js-player'));

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

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 Uiza(p));

...or use a static method where you can pass a CSS string selector, a NodeList, an Array of HTMLElement, or a JQuery object:

const players = Uiza.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.

Options

The second argument for the constructor is the options object:

const player = new Uiza('#playerUz', {
  title: 'Example Title',
});

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

<video src="/path/to/video.mp4" id="playerUz" controls data-uiza-config='{ "title": "Example Title" }'></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 Uiza. This would allow you to do a User Agent check or similar to programmatically enable or disable Uiza 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 the default controls are used, 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	`uiza`	Specify the id prefix for the icons used in the default controls (e.g. "uiza-play" would be "uiza"). 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.Uiza.io/static/blank.mp4`	Specify a URL or path to a blank video file used to properly cancel network requests.
`autoplay`²	Boolean	`false`	Autoplay the media on load. If the `autoplay` attribute is present on a `<video>` or `<audio>` element, this will be automatically set to true.
`autopause`¹	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, container: null }`	`enabled`: Toggles whether fullscreen should be enabled. `fallback`: Allow fallback to a full-window solution (`true`/`false`/`'force'`). `iosNative`: whether to use native iOS fullscreen when entering fullscreen (no custom controls). `container`: A selector for an ancestor of the player element, allows contextual content to remain visual in fullscreen mode. Non-ancestors are ignored.
`ratio`	String	`null`	Force an aspect ratio for all videos. The format is `'w:h'` - e.g. `'16:9'` or `'4:3'`. If this is not specified then the default for HTML5 and Vimeo is to use the native resolution of the video. As dimensions are not available from YouTube via SDK, 16:9 is forced as a sensible default.
`storage`	Object	`{ enabled: true, key: 'uiza' }`	`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`: The speed options to display in the UI. YouTube and Vimeo will ignore any options outside of the 0.5-2 range, so options outside of this range will be hidden automatically.
`quality`	Object	`{ default: 576, options: [4320, 2880, 2160, 1440, 1080, 720, 576, 480, 360, 240] }`	`default` is the default quality level (if it exists in your sources). `options` are the options to display. This is used to filter the available sources.
`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.
`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.
`previewThumbnails`	Object	`{ enabled: false, src: '' }`	`enabled`: Whether to enable the preview thumbnails (they must be generated by you). `src` must be either a string or an array of strings representing URLs for the VTT files containing the image URL(s). Learn more about preview thumbnails below.

API

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

Object

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

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

You can also access the object through any events:

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

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`.
`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.
`poster`¹	String	The URL for the poster image (HTML5 video only).
`tracks`¹	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/uiza/1.0/example_captions_en.vtt" default>` and similar for the French version. Booleans are converted to HTML5 value-less attributes.
`previewThumbnails`¹	Object	The same object like in the `previewThumbnails` constructor option. This means you can either change the thumbnails vtt via the `src` key or disable the thumbnails plugin for the next video by passing `{ enabled: false }`.

HTML5 only

Events

You can listen for events on the target element you setup Uiza 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.uiza property. Here's an example:

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