In case we set videoNode.subtitleConfig = {trackName: “eia608/1”}

[https://developer.roku.com/docs/developer-program/getting-started/architecture/content-metadata.md](https://developer.roku.com/docs/developer-program/getting-started/architecture/content-metadata.md)

Then the videNode.availableSubtitleTracks returns an array with one element for the videos **without**  **CC**.

How to identificate is video has CC track or not?

In the manifest there no “#EXT-X-MEDIA” key but the videNode.availableSubtitleTracks returns an array with one element
