Does $('video') work with audio?

Does $('video') work with audio?


I have a webpage I wrote a few years ago that has statements such as:

  1.   try
  2.             {
  3.                       myTextTrack = $('video').get(0).addTextTrack('metadata', 'myLabel', 'en');
  4.             }         
  5.   catch(err)
  6.            {
  7.                         alert(err);
  8.                         return;
  9.             }
  10.   

I tried it out recently, and it crashes with audio files like mp3's.   Does 'video' not apply in that case?   Would I use something like 'audio' (if it exists)?
Thanks.
