getAvailableAudioTracks

Description

Returns the list of available audio tracks for the current content.

Each of the objects in the returned array have the following properties:

• active (Boolean): Whether the track is the one currently active or not. Only maximum one audio track can be active at a time.

• id (string): The id used to identify the track. Use it for setting the track via setAudioTrack.

• language (string): The language the audio track is in, as set in the Manifest.

• normalized (string): An attempt to translate the language property into an ISO 639-3 language code (for now only support translations from ISO 639-1 and ISO 639-2 language codes). If the translation attempt fails (no corresponding ISO 639-3 language code is found), it will equal the value of language

• audioDescription (Boolean): Whether the track is an audio description of what is happening at the screen.

• dub (Boolean|undefined): If set to true, this audio track is a "dub", meaning it was recorded in another language than the original. If set to false, we know that this audio track is in an original language. This property is undefined if we do not known whether it is in an original language.

• label (string|undefined): A human readable label that may be displayed in the user interface providing a choice between audio tracks.

  This information is usually set only if the current Manifest contains one.

  • id (string): The id used to identify this Representation.

  • bitrate (Number): The bitrate of this Representation, in bits per seconds.

  • codec (string|undefined): The audio codec the Representation is in, as announced in the corresponding Manifest.

  • isSpatialAudio (Boolean|undefined): If set to true, this Representation has spatial audio.
