The read-only VideoTrack property language returns a string identifying the language used in the video track. For tracks that include multiple languages (such as a movie in English in which a few lines are spoken in other languages), this should be the video's primary language.


var videoTrackLanguage = VideoTrack.language;


A DOMString specifying the BCP 47 (RFC 5646) format language tag of the primary language used in the video track, or an empty string ("") if the language is not specified or known, or if the track doesn't contain speech.

For example, if the primary language used in the track is United States English, this value would be "en-US". For Brazilian Portuguese, the value would be "pt-BR".
