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.

The default call-to-action text is Play. You can also localize this message for your viewers.

Default: false
displaytitle boolean Configures if the title of a media file should be displayed

defaultBandwidthEstimate number 8.3.0+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.


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.

Default: 50000
fullscreenOrientationLock string 8.28.0+(Android) Enables player to rotate in a mobile web view as a viewer rotates a mobile device

Possible Values:
  • landscape: (Default) Locks to a landscape orientation, readjusting at a 180º turn of the device

This property can accept any value between 5-30. Leave blank in 8.19.0+ for the player to determine target latency based on the stream.

Default: 25 <8.19.0
mute boolean Defines 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.

Default: false
nextupoffset number | string 8.9.0+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%")

Rendering and Loading

Default: /
hlsjsdefault booleanMakes HLSjs the default provider when using Chrome for Android

Disable this property to use the browser's default provider.

Default: true
liveTimeout 8.1.9+ numberConfigures 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.

  • liveTimeout defaults to a value equal to three times (3x) the targetDuration value defined in the manifest.


    For more information on targetDuration, see the HLS spec.

  • For Safari,liveTimeout defaults to 30.
loadAndParseHlsMetadata booleanTo 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:
  • true: (Default) 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.
preload stringTells the player if content should be loaded prior to playback

This is useful for faster playback speed or if certain metadata should be loaded prior to playback.

Possible values:
  • metadata: (Default) 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
  • none: No content preloaded. This option is recommended if you are concerned about excess content usage.
showUIWhen 8.32.0+ stringTells the player when to show the player UI

Possible values:
  • onReady: (Default) Show the UI when the player is loaded
  • onContent: Hide the player UI until ad or video content is ready to play
