Properties

accessibilityPurpose ↔ dynamic

The DASH accessibility descriptor, if one was provided for this track. For text tracks, this describes the text; otherwise, this is for the audio.

getter/setter pair

active ↔ bool?

If true, this is the track being streamed (another track may be visible/audible in the buffer).

getter/setter pair

audioBandwidth ↔ num?

nullable (only for variant tracks) The audio stream's bandwidth if known.

getter/setter pair

audioCodec ↔ String?

The audio codecs string provided in the manifest, if present.

getter/setter pair

audioId ↔ num?

getter/setter pair

audioMimeType ↔ String?

The audio MIME type of the content provided in the manifest.

getter/setter pair

audioRoles ↔ List?

Array.

getter/setter pair

audioSamplingRate ↔ num?

getter/setter pair

bandwidth ↔ num?

The bandwidth required to play the track, in bits/sec.

getter/setter pair

channelsCount ↔ num?

getter/setter pair

codecs ↔ String?

The audio/video codecs string provided in the manifest, if present.

getter/setter pair

forced ↔ bool?

indicates that this in the forced text language for the content. This flag is based on signals from the manifest.

getter/setter pair

frameRate ↔ num?

The video framerate provided in the manifest, if present.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, override

hdr ↔ String?

The video HDR provided in the manifest, if present.

getter/setter pair

height ↔ num?

number

getter/setter pair

id ↔ num?

The unique ID of the track.

getter/setter pair

kind ↔ String?

nullable (only for text tracks) The kind of text track, either 'caption' or 'subtitle'.

getter/setter pair

label ↔ String?

The track label, which is unique text that should describe the track.

getter/setter pair

language ↔ String?

The language of the track, or 'und' if not given. This value is normalized as follows - language part is always lowercase and translated to ISO-639-1 when possible, locale part is always uppercase, i.e. 'en-US'.

getter/setter pair

mimeType ↔ String?

The MIME type of the content provided in the manifest.

getter/setter pair

originalAudioId ↔ String?

nullable (variant tracks only) The original ID of the audio part of the track, if any, as it appeared in the original manifest.

getter/setter pair

originalImageId ↔ String?

nullable (image tracks only) The original ID of the image track, if any, as it appeared in the original manifest.

getter/setter pair

originalLanguage ↔ String?

nullable The original language of the track, if any, as it appeared in the original manifest. This is the exact value provided in the manifest; for normalized value use language property.

getter/setter pair

originalTextId ↔ String?

nullable (text tracks only) The original ID of the text track, if any, as it appeared in the original manifest.

getter/setter pair

originalVideoId ↔ String?

nullable (variant tracks only) The original ID of the video part of the track, if any, as it appeared in the original manifest.

getter/setter pair

pixelAspectRatio ↔ String?

The video pixel aspect ratio provided in the manifest, if present.

getter/setter pair

primary ↔ bool?

True indicates that this in the primary language for the content. This flag is based on signals from the manifest. This can be a useful hint about which language should be the default, and indicates which track Shaka will use when the user's language preference cannot be satisfied.

getter/setter pair

roles ↔ List?

roles Array.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

spatialAudio ↔ bool?

True indicates that the content has spatial audio. This flag is based on signals from the manifest.

getter/setter pair

tilesLayout ↔ String?

The value is a grid-item-dimension consisting of two positive decimal integers in the format: column-x-row ('4x3'). It describes the arrangement of Images in a Grid. The minimum valid LAYOUT is '1x1'.

getter/setter pair

toJS → dynamic

no setter

type ↔ String?

The type of track, either 'variant' or 'text' or 'image'.

getter/setter pair

videoBandwidth ↔ num?

nullable(only for variant tracks) The video stream's bandwidth if known.

getter/setter pair

videoCodec ↔ String?

The video codecs string provided in the manifest, if present.

getter/setter pair

videoId ↔ num?

nullable (only for variant tracks) The video stream id.

getter/setter pair

videoMimeType ↔ String?

The video MIME type of the content provided in the manifest.

getter/setter pair

width ↔ num?

The video width provided in the manifest, if present.

getter/setter pair
