This article contains all configuration options JW Player supports.

IMPORTANT:

Certain JW Player features may require a specific license. Please contact our team if your license does not support the features or configuration options you need.


Introduction

JW Player contains a number of configurable options. Some options, like width or mute, are top level, while other more advanced options may be nested, such as the ones used for skin customizations and advertising.

Here is an example setup that contains both setup options and specific advertising options:

jwplayer("myElement").setup({
  "playlist": "https://example.com/myVideo.mp4",
  "height": 360,
  "width": 640,
  "autostart": "viewable",
  "advertising": {
    "client": "vast",
    "tag": "http://adserver.com/vastTag.xml"
  }
});


Setup Options

These are the options for configuring the layout and playback behavior of a player. Each is placed directly into the setup of the player.

Appearance

Property Description Default
aspectratio string
                                                                     		 Maintains proportions when width is a percentage. Will not be used if the player is a static size.
Must be entered in ratio "x:y" format.		 -
controls boolean Whether to display the video controls (control bar and display icons) true
displaydescription boolean Configures if the description title of a media file should be displayed true
displayHeading 8.6.0+ boolean (Outstream only) Controls if heading above the outstream player is displayed

Possible values include:

• false: No heading is shown

• true: Heading is shown with default text: Advertisement.

Use intl.{lang}.displayHeading to customize or localize text.		 false
displayPlaybackLabel 8.6.0+ boolean Enables call-to-action text beneath the play button on the player idle screen.

When set to true, you can potentially see up to a 5% increase in the number of times viewers click the play button to watch a video.

The default call-to-action text is "Play." You can also localize this message for your viewers.		 false
displaytitle boolean Configures if the title of a media file should be displayed true
height number The desired height of your video player (in pixels). Should be omitted when aspectratio is configured 360
qualityLabels array By default, the JW Player will set video quality levels using information from the manifest files. Use this configuration option to apply a custom quality label to a desired bandwidth in kbps, works for HLS and DASH. For example: qualityLabels:{"2500":"High","1000":"Medium"} -
nextUpDisplay boolean Configures whether the Next Up modal is displayed -
renderCaptionsNatively 8.0.1+ boolean (Chrome and Safari only) Determines if the renderer of the browser or of the player is used to display captions

Possible values include:

true: Captions render using the renderer of the browser.

false: Captions render using the renderer of the player.

Note: See also: captions		 false (Chrome)

true (Safari)
stretching string Resize images and video to fit player dimensions. See graphic below for examples
"uniform" — Fits JW Player dimensions while maintaining aspect ratio
"exactfit": Will fit JW Player dimensions without maintaining aspect ratio
"fill"— Will zoom and crop video to fill dimensions, maintaining aspect ratio
"none" — Displays the actual size of the video file. (Black borders)		 uniform
width number | string The desired width of your video player (in pixels or percentage) 640

Behavior

Property Description Default
aboutlink string Custom URL to link to when clicking the right-click menu https://www.jwplayer.com/learn-more
abouttext string Custom text to display in the right-click menu -
autostart string
                                                                     		 Whether the player will attempt to begin playback automatically when a page is loaded. Set to 'viewable' to have player autostart if 50% is viewable. false
defaultBandwidthEstimate 8.3.0+ number When set, suggests an initial bandwidth estimate (in bits per second) which overrides the default bandwidth estimate of the player for new viewers to your site

Use case: New users to your site may experience low-quality video for several seconds before the quality adapts to the connection speed at which content is delivered. This speed may be limited by their connection speed. In this case, you would want to confirm that the majority of your viewers have fast connections.

NOTE: Since this property sacrifices player performance for video quality, it is strongly recommended not to set this property. The player is optimized to select the best bandwidth after several seconds.		 50000
liveSyncDuration 8.12.0+ number Defines the distance from the live edge in seconds in the following scenarios:

• The player attempts to start a live or DVR stream
• A user clicks the Live button to return to the live content of the stream

This property can accept any value between 5-30.		 25
mute boolean Configures if the player should be muted during playback

If a user overrides this property, the user’s action will persist for the duration of the user session. For example, if all players are configured with mute: true and a user unmutes a player, each subsequent player that the user encounters will start unmuted.		 false
nextupoffset 8.9.0+ number | string Configures when the Next Up card displays during playback

A positive value is an offset from the start of the video. A negative value is an offset from the end of the video. This property can be defined either as a number (-10) or a percentage as a string ("-2%")		 -10
playbackRateControls boolean Whether to display a settings menu to adjust playback speed. If true, the pre-defined options available in the menu are 0.5x, 1x, 1.25x, 1.5x, and 2x. An array can be passed to customize the menu options using playbackRates. Note: This feature is not currently supported in Android with HLS streams. false
playbackRates 8.0+ array of numbers Custom playback rate options to display in the settings menu. [0.25, 0.75, 1, 1.25]
playlistIndex 8.15.0+number Item within a playlist to start playback

Within the playlist, the first index is 0.

If the playlistIndex value is negative, the index starts counting from the end of the playlist. A negative value cannot exceed the absolute number of playlist items. For example, in a playlist of 5 items, "playlistIndex": -5 is the lowest acceptable negative number.

This property applies to JSON, RSS, and array playlists.		 -
repeat boolean Configures if the player should loop content after a playlist completes false


Media

NOTE

The following properties are related to media that is loaded into the player.

You should use the playlist object to define the content that is loaded into the player.

If you have a single content item to load in a player, you can use the following properties to define this item directly within jwplayer().setup. If you are planning on using multiple media items, these can also be used inside of a playlist array.

Property Description Default
file string
                                                                     		 URL to a single video file, audio file, or live stream to play

Can also be configured inside of a sources array		 -
description string A description of your video or audio item -
image string URL to a poster image to display before playback starts. -
mediaid string Unique identifier of this item. Used by advertising, analytics and discovery services -
title string The title of your video or audio item -
type string Defining the video file type is required when using a media file url that does not have an extension.

Possible values:

• aac
• mp4
• f4a
• f4v
• hls
• m3u
• m4v
• mov
• mp3
• mpeg
• oga
• ogg
• ogv
• vorbis
• webm		 -

YouTube and RTMP media formats are no longer supported.8.0+


Rendering and Loading

Property Description Default
base string Configures an alternate base path for skins and providers /
flashplayer string Specifies an alternate directory of jwplayer.flash.swf /
hlsjsdefault boolean Makes HLSjs the default provider when using Chrome for Android. Disable to use the browser's default provider. true
liveTimeout 8.1.9+ number
                                                                     		 Configures how a stalled live manifest is handled

This property accepts a positive number in seconds, but values between 1-10 are ignored. Set this property to 0 to configure a stream to never time out.

The player will continue requesting manifests until it times out. If a live manifest does not update after being requested for longer than liveTimeout, the stream will end with an error event. If you want a stream to end immediately, include an end tag in the manifest.

This configuration option only handles stalled manifests, not issues with segment loading. A chunk that results in a 404, for example, will still error out.		 30
loadAndParseHlsMetadata boolean To enable HLS playback in Safari to trigger the same metadata events that are triggered during HLS playback in Chrome, the player will make additional requests to HLS playlists provided they contain PROGRAM-DATE-TIME tags that the player can use to embed timed metadata.

Possible values include the following:

• true: The player loads and parses the playlist manifest as it is loaded by Safari and synchronizes the results with media playback. This will also result in multiple manifest requests

• false: Prevents the player from sideloading live HLS manifests to parse out-of-band manifest metadata that Safari does not expose like DATERANGE, CUE-OUT, CUE-IN, and DISCONTINUITY tags.		 true
preload string Tells the player if content should be loaded prior to playback. Useful for faster playback speed or if certain metadata should be loaded prior to playback:

• none: Player will explicitly not preload content. (Recommended if you are concerned about excess content usage.)
• metadata: Loads the manifest and buffers a maximum of one segment of media for HLS and Dash streams.
• auto: Loads the manifest and buffers approximately 30 seconds worth of media segments.		 metadata

Property Description
mediationLayerAdServer* string
                                                                     		 (Required) Mediation layer that decides which ad runs

• jwp: (VAST/IMA) An auction is conducted by the player. If a winner is selected, the winner's ad is called. If no winner is selected, the fallback tag is called. You must specify a floor price - floor price - The value (in cents) that a bid must exceed to qualify to win an auction .

• jwpspotx: (VAST) No auction is conducted by the player. The player asks SpotX for a bid and calls the returned ad response regardless of price. This option is equivalent to using JW Player mediation with a $.01 floor price - floor price - The value (in cents) that a bid must exceed to qualify to win an auction . You must set up SpotX line items.

• dfp: (IMA) No auction is conducted by the player. All bids are sent to Google Ad Manager (GAM, formerly known as DFP) and rendered as line items that compete against other line items. GAM serves the winning line item. We recommend setting buckets to minimize the number of line items that you must set up in GAM.

• jwpdfp: (IMA) An initial auction is conducted by the player. If a winner is selected, the winner's ad will is called. If no winner is selected, the fallback tag is called to serve. If no winner is selected for any reason, all valid bids are sent to Google Ad Manager (GAM, formerly known as DFP) where the bid values are rendered as line items to compete against other line items. The winning line item is served by GAM. You must set floorPriceCents. We recommend setting buckets to minimize the number of line items that you must set up in GAM.

Default value: jwp
buckets array (Recommended) Ranges of bid prices

When using buckets, bid prices sent to GAM are rounded down to the closest specified increment. Price buckets are helpful to reduce the number of line items in GAM. Without price buckets, one line item per one-cent increment is required.

This property only applies when dfp or jwpdfp (only for the GAM portion of the mediation) is selected as the mediationLayerAdServer.
bidTimeout string 8.13.0+ Timeout for bid response from when the bid request occurs, in milliseconds

Default value: 2000

Default value: 2000
floorPriceCents number Price in cents (CPM) that a bid has to beat in order to win

This property must be set when mediationLayerAdServer is set to jwp or jwpdfp.

NOTE: Determining the best floor price - floor price - The value (in cents) that a bid must exceed to qualify to win an auction depends upon various factors. If you need assistance determining the best floor price, please consult with your JW Player representative or SSP partner.
floorPriceCurrency string Currency of the floorPriceCents

This property must be set to usd when mediationLayerAdServer is set to jwp.

Ad Schedules with VMAP Files

If you are planning on using a VMAP file, add the link to a VMAP .xml file as the value for schedule:

jwplayer("myElement").setup({
  "playlist": "https://cdn.jwplayer.com/v2/playlists/a12bc3D4",
  "advertising": {
    "client": "vast",
    "adscheduleid": "t4Xk5tsF",
    "schedule": "myvmap.xml"
  }
});

The VMAP schedule will then be applied to each playlist item. See our article about VMAP schedules for more information.

Embedded Ad Schedules with JSON

In order to use a JSON-formatted schedule, you must define at least one ad break configured inside of the schedule property. Each ad break should include an offset and a tag or vastxml.

jwplayer("myElement").setup({
  "playlist": "https://cdn.jwplayer.com/v2/playlists/a12bc3D4",
  "advertising": {
    "client": "vast",
    "adscheduleid": "p4Xk5lsZ",
    "schedule": [
      {
        "tag": "myPreroll.xml",
        "offset": "pre",
        "custParams": {
          "testkey1": "testval1",
          "testkey2": "testval2"
        },
      },
      {
        "vastxml": "<VAST version='2.0'> ... </VAST>",
        "offset": "50%"
      }
    ]
  }
});

vastxml string (VAST only) VAST XML ad tag that is requested during the configured ad break

Do not use this property and advertising.schedule[].tag within the same ad break.		 -


Auto pause

Automatically pauses the player based on certain rules

By default, adding an empty autoPause object enables the auto pause player functionality and also sets viewability: true.

jwplayer("myElement").setup({
  "playlist": "https://example.com/myVideo.mp4",
  ...
  "autoPause": {
    "viewability": true,
    "pauseAds": true

Casting

Casting enables a viewer to use Google Cast or Apple AirPlay technologies to stream video and audio content to a compatible TV or sound system. By enabling the casting feature for a player, a viewer can tap an icon in the control bar to stream your content on a cast-compatible device. If no compatible device is detected by the player, no cast icon appears.

See also: FAQs

To enable casting, add an empty cast object in your setup.

jwplayer("myElement").setup({
  "playlist": "https://cdn.jwplayer.com/v2/playlists/1a2Bc3d4",
  "height": 360,
  "width": 640,
  "cast": {}
});

If you are using a custom receiver, assign the identifier of the custom receiver to the cast.customAppId property.

jwplayer("myElement").setup({
  "playlist": "https://cdn.jwplayer.com/v2/playlists/1a2Bc3d4",
  "height": 360,
  "width": 640,
  "cast": {
    "customAppId": "XXXXXX"

                                                                     		 (Optional) When using a custom receiver, the identifier of the receiver app


DRM

IMPORTANT

Video content protection requires a JW Player Enterprise license. Please contact our team to upgrade your account.

Configuration options related to DRM for MPEG DASH (Playready, Widevine, Clearkey) and HLS streams (Fairplay).

JW Player includes the ability to add DRM to a specific playlist source. Using this method will allow your browser to choose the correct DRM method when multiple DRM types are configured. We highly suggest updating any configurations to use this new method.

NOTE

HTTPS is required for all DRM-protected content.

For more information regarding DRM, and for examples, please view our support article.

drm.playready

Playready DRM is specific to Internet Explorer 11 and Edge on Windows 8.1 or higher operating systems.

Property Description Default
url* string (Required) The URL of the PlayReady license server -
headers array Specifies the custom http headers to send to your playready license server. See headers for more information -
licenseRequestFilter function Expects a function which takes a single request argument. License request filters intercept license requests before 'licenseRequestHeaders' are added. -
licenseResponseFilter function
                                                                     		 Expects a function which takes a single response argument. License response filters intercept license responses before updating the session with the license key. -

drm.widevine

Widevine DRM is specific to Google Chrome on non-iOS devices. Widevine will also function on Firefox browsers for desktop systems.

Property Description Default
url* string (Required) The URL of the WideVine license server -
headers array Specifies the custom http headers to send to your widevine license server requests. See headers for more information -
licenseRequestFilter function Expects a function which takes a single request argument. License request filters intercept license requests before 'licenseRequestHeaders' are added. -
licenseResponseFilter function
                                                                     		 Expects a function which takes a single response argument. License response filters intercept license responses before updating the session with the license key. -
serverCertificateUrl string The URL of the WideVine service certificate -

drm.[widevine/playready].headers

Adding customized HTTP header data to license requests is possible with the "headers" configuration. This replaces the static "customData" configuration option in both widevine and playready scenarios. It is also possible to add multiple custom http headers by including multiple objects in the "headers" array.

DRM can be configured in the following way:

"drm": {
  "playready": {
    "url": "mydrmserver.com",
    "headers": [{
      "name": "customData",
      "value": "hereismycustomdatastring"
    }]
  }
}

In previous versions, adding "customData" would look like the following:

"drm": {
  "playready": {
    "url": "mydrmserver.com",
    "customData": "hereismycustomdatastring"
  }
}
Property Description
name string
                            		 The name of the http header that will be included
value string The value of the http header that will be included

drm.fairplay

processSpcUrl* string | function (Required) The path to the license server (server playback context) which provides the ckc. Expects a direct url to the server. If the url needs to be constructed dynamically, a custom function can be passed to this configuration option which returns the url
extractContentId function Expects a function that receives the initData uri (converted to a string) from the needkey event, and returns the contentId which is part of the session data used to initialize the keySession
extractKey function Expects a function that receives the ckc returned by the license server and returns the key used to update the active key session. If the key can only be extracted asynchronously (for example reading bytes from a ‘blob’ response), this function can return a promise
licenseResponseFilter function Expects a function which takes a single response argument. License response filters intercept license responses before updating the session with the license key.
licenseResponseType string Specifies the data type returned by the XHR request to the license server. The default value is 'arraybuffer'. Other options include 'blob', 'json', and 'text'. This option impacts how “licenseRequestMessage” will be processed
licenseRequestFilter function Expects a function which takes a single request argument. License request filters intercept license requests before 'licenseRequestHeaders' are added.
licenseRequestHeaders array Expects an Array of Objects containing header “name” and “value” properties to be included in the request to the license server
licenseRequestMessage function Expects a function that receives the license key message and returns the message to be sent to the license server. With the default “licenseResponseType” of ArrayBuffer this function passes through keymessage event message property without any changes

drm.clearkey

A basic form of DRM that lists a decryption key inside of your player configuration. This is the least secure form of DRM, though it is the simplest to implement across browsers.

key* string
                                      		 (Required) The key required to decrypt DRM content
keyId* string (Required) The key ID specified in the mpd's default_KID value


Float on scroll

Keeps the player visible when the original player location is scrolled out of view by minimizing it to a corner of the screen

On devices in portrait orientation, the player becomes fixed to the top of the page using its original dimensions.

When floating, the viewer can drag the player to reposition it. This functionality is disabled during ad playback.

By default, adding an empty floating object enables the floating player functionality and also sets dismissible: true.

Use the following CSS classes to customize the floating player:

Important

Float on scroll cannot be used with a player that is embedded in an iframe.

jwplayer("myElement").setup({
  "playlist": "https://cdn.jwplayer.com/v2/playlists/{PLAYLIST_ID}",
  ...
  "floating": {
    "dismissible": true
  }
});
Property Description Default
dismissible boolean
                                             		 Permits or prohibits closing the floating player

• true: The floating player can be closed by a viewer.

•false: The floating player cannot be closed by a viewer.		 true
mode 8.17.0+ string Tells the player how the floating behavior should operate

Custom trackers with gtag.js implementations are not supported.		 -

Google's separate JavaScript library and config needs to be included in your page's head in order to send events with JW Player. Setting an empty "ga":{} options block will enable basic Google Analytics integration. No additional nested config options are required.

See Connecting Google Analytics for more information.


Internationalization

The intl object allows you to add new language translations, customize translations for player text and aria-label values, and access the benefits of the automated player localization feature.

IMPORTANT

Any existing language customizations or translations made outside of the intl object will override both automated player localization and intl object customizations. If you have configured language customizations or translations outside of the intl object, use the table below to copy those values into the corresponding intl.{lang}.{property}.

For each language, use a two-letter or locale-specific language code to define language-specific objects. Use the code example and tables below to configure the intl object.

playlist[].adschedule[]

IMPORTANT:

Video ad insertion requires a JW Player Enterprise license. Please contact our team to upgrade your account.

The playlist[].adschedule[] property is used for scheduling ad breaks throughout specific playlist items. You must define at least one ad break configured inside of the adschedule property. Each ad break should include an offset and a tag or vastxml.

Property Description
offset string OR number
                                                                     		 (Required) When to play the configured ad tag

• pre: Ad plays as a preroll

• post: Ad plays as a postroll

• xx%: (VAST only) Ad plays after xx% of the content

• number: Ad plays after the specified number of seconds
tag string (Required) When a string, URL of the ad tag for VAST and IMA plugins, or a string place holder for FreeWheel

(VAST plugin only) When an array, URLs of the VAST ad tags to be used as fallbacks in the event that one or multiple ad tags fail to render

When a VAST tag is used, ad tag targeting macros can be added to define features such as GDPR consent.

Do not use this property and playlist[].adschedule[].vastxml within the same ad break.
type string Property indicating the format of the ad to be served within the ad break

• linear: Video ad that interrupts video content playback

• nonlinear: Static display ad that overlays a portion of the player and does not interrupt playback. No advertisting cuepoint is shown for this ad break.

If a mix of linear and non-linear ads will serve within an ad break, do not set this property. The player will interrupt video playback for linear ads and will not interrupt video playback for non-linear ads.
vastxml string VAST XML ad tag that is requested during the configured ad break

Do not use this property and advertising.schedule[].tag within the same ad break.		 
jwplayer("myElement").setup({
  "playlist": [{
      "title": "One Media Item",
      "description": "Only One media item in a playlist!",
      "file": "myFile.mp4",
      "mediaid": "ddrx3v2",
      "image": "myImage.png",
      "adschedule": [{
          "offset": "pre",
          "tag": "myAdTag.xml"
        },
        {
          "offset": 10,
          "tag": "myMidroll.xml"
      }]
  }]
});

playlist[].sources[]

Sources are inserted into playlist objects and are lists of files. Sources serve a dual purpose, depending on the files used:

  • Use different file types: Alternate "fallback" media sources
  • Use the same file type: Toggle quality with static video files

Alternate Media Sources

If using different file types, sources prioritizes which file to play only in the case when a provider (HTML5, HLS, or DASH) fails to load. If there is an error with a stream, the player will not failover to the next provider. In the example below, the player will attempt to play myVideo.m3u8 as a first choice.

In the event that a browser cannot play an m3u8, the player is intelligent enough to choose myVideo.mp4 instead. In the event that an mp4 cannot be played, the player will attempt the webm format before producing an error.

jwplayer("myElement").setup({
  "playlist": [{
    "title": "One Playlist Item With Multiple Sources",
    "description": "Three Sources - One Playlist Item",
    "image": "myImage.png",
    "mediaid": "ddrx3v2",
    "sources": [{
        "file": "myVideo.m3u8"
      },{
        "file": "myVideo.mp4"
      },{
        "file": "myVideo.webm"
    }]
  }]
});

Sources with DRM

When using DRM, we highly suggest placing the drm block inside of the appropriate media source. This ensures the correct media and DRM pair gets chosen for the appropriate browser. For example:

  "sources": [{
      "file": "myFairplayStream.m3u8",
      "drm": {
        "fairplay": {
          "certificateUrl": "http://myfairplay.com/fairplay/cert",
          "processSpcUrl": "http://myfairplay.com/fairplay/ckc"
        }
      }
    },{
      "file": "myWidevineStream.mpd",
      "drm": {
        "widevine": {
          "url": "http://mywidevineurl.com/drm"
          }
      }
    },{
      "file": "myPlayreadyStream.mpd",
      "drm": {
        "playready": {
          "url": "http://myplayreadyurl.com/drm"
          }
      },{
      "file": "myClearkeyStream.mpd",
      "drm": {
        "clearkey": {
          "key": "1234clear5678key",
          "keyId": "fefde00d-efde-adbf-eff1-baadf01dd11d"
          }
      }
    }]

See our drm section for more information.

Manifest and Segment Requests with Custom Headers

You can add custom headers to media XHR requests by using the onXhrOpen callback. This gets executed after XMLHTTPRequest.open() and before XMLHTTPRequest.send() for HLS manifest, key and segment requests made by the player. This is not available in Safari browsers where HLS is played natively.

jwplayer().setup({
  playlist: [{
      sources: [{
          file: 'video.m3u8',
          onXhrOpen: function(xhr, url) {
            xhr.setRequestHeader('customHeader', 'customHeaderValue');
          }
      }]
  }]
})

For HLSjs playback only.

Quality Settings for Video Files

In the event that a streaming technology like HLS or DASH cannot be used, listing video files of different qualities will enable a quality selection settings menu in the player. Compared to other streaming methods, it has the following drawbacks:

  • No automatic switching, based on bandwidth or download speed
  • Changing qualities may cause playback stuttering
  • Pseudostreaming may need to be configured in cases where Flash is used
jwplayer("myElement").setup({
  playlist: [{
      title: "One Playlist Item With Multiple Qualities",
      description: "Two Qualities - One Playlist Item",
      sources: [{
          file: "myVideo-720p.mp4",
          label: "HD"
        },{
          file: "myVideo-480p.mp4",
          label: "SD"
      }]
  }]
});
Property Description
file string
                                                                     		 (Required) URL to the video file, audio file, YouTube video or live stream of this playlist item source.
default boolean Set this to true for the media source you want to play on startup. If this isn't set for any source, the first one is used
drm object An object containing DRM information for a particular source
label string Label of the media source, displayed in the manual quality selection menu. Set this if you have more than 2 qualities of your video.
type string Forces a media type. Only required when a file extension is missing or not recognized (Using .php or certain tokens, for example)

playlist[].tracks[]

Tracks can be attached to media for three possible reasons: captions, thumbnails, or chapters. Thumbnail and chapter files must be in WEBVTT format. Captions accept WEBVTT, SRT, and DFXP format, though JW Player strongly suggests using WEBVTT if possible.

Property Description Default
default boolean
                                                                     		 Only for captions. Set this to true if you want a captions track to display by default -
file string URL to the captions, chapters or thumbnails text track file. See Adding Closed Captions for an example setup. -
kind string The kind of text track.
"captions": Captions that display during video playback.

"chapters": Places markers on the video er, displaying different sections
"thumbnails": A list of thumbnails that appear when the mouse cursor hovers on the timeslider.		 "captions"
label string Label of the text track. Is only used in setups with multiple captions, where the label is displayed in the CC selection menu. index

When using the playlist to load an RSS feed, these options are set in the feed. See the Media Formats Reference for a mapping of all playlist options to RSS format.

360 videos

WARNING

VR and Cardboard Mode are not currently working due to a deprecated Apple API. A fix is forthcoming in Summer 2020.

Playlist configuration options described above can be used with spherical videos. Below are 360-specific options.

Property Description Default
