I've observed an issue on a demo website where the textTracks on the video element are not present. Interestingly, my work project exhibits a similar behavior. Additionally, I've noticed that for some content on the demo site (i couldnt find that content again), there existsShaka Player's textTrack object that contains two keys, activeCue and cue, both of which are empty. Despite this, subtitles are still being rendered in the player.

Could you please help me understand what configuration settings I need to pass to access the vttCue from video.textTracks? I would like to ensure that I can properly access and utilize the cues for custom subtitle rendering by accessing the cue and then rendering it programmatically in the DOM (am sure this must be doable).

The way Shaka works in the Demo does not use texttracks, we use our own displayer to show the subtitles. Sorry!
