How to identify which track should be enabled in HTML if the users preferences dont indicate that another track is more suitable?

If you provide two subtitle tracks for your video, use the default attribute to identify which track to enable.

Example

You can try the following code to implement the default properties of the track -

<!DOCTYPE HTML>
<html>
   <body>
      <video width = "300" height = "200" controls autoplay>
         <source src = "/html5/foo.ogg" type = "video/ogg" />
         <source src = "/html5/foo.mp4" type = "video/mp4" />
         <track src = "subtitles_en.vtt" kind = "subtitles" srclang = "en" label = "English">
         <track src = "subtitles_ru.vtt" kind = "subtitles" srclang = "ru" label = "Russia" default>
         Your browser does not support the video element.
      </video>
   </body>
</html>
Copy after login
