getAvailableTextTracks

Description

Returns the list of available text tracks (subtitles) for the current content.

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

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

  • language (string): The language the text 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

  • closedCaption (Boolean): Whether the track is specially adapted for the hard of hearing or not.

  • active (Boolean): Whether the track is the one currently active or not.

Note for multi-Period contents:
This method will only return the available tracks of the Period that is currently playing.
In DirectFile mode (see loadVideo options), if there is no supported tracks in the file or no track management API in the browser this method will return an empty Array.
