Setting TextTrack to defaults not working when text track and video player are created dynamically.

[Pinank08]

Description

I wan't to create a dynamic video player i.e. video src and caption src comes from different file on click event.

Steps to reproduce

Explain in detail the exact steps necessary to reproduce the issue.

1. I have created a dynamic video player in videojs.
2. Than to add text track I have used addRemoteTextTrack() function.
3. But I am not able to make the track added as default as it always selects subtitle off as default.

Here is the code that I have used.

var oldTracks = player.remoteTextTracks();
  var i = oldTracks.length;
  while (i--) {
    player.removeRemoteTextTrack(oldTracks[i]);
  }

var trackk = new function() {
    this.kind = 'subtitles';
    this.label = 'english';
    this.language = 'en';
    this.id='track1';
    this.src = url+'.vtt';
    this.default= 'true'; // i have tried default too
}
    player.addRemoteTextTrack(trackk, true);

/*  I have used 
player.TextTrack = 'default';
player.TextTracks.mode='showing';
and many more... but subtitles are always off bydefault
*/ 

Results

Expected

I Expect to see subtitles when video is loaded.

Actual

When Video is loaded subtitles are off.

@Pinank08 please see my description in #4403. Are you using version 6.x? If so, please let us know because your problem is likely caused by #4403. Can you try the workarounds I show in that example to see if they fix your issue?

Closing as potentially fixed and due to lack of activity. If we get more information, we can re-open.

I am having this problem with version 6.6.2.

Actually, I have the video and a default track loaded initially with HTML tags, and the track is selected by default...this works fine. The page implements a very rudimentary subtitle editor...for now, any time a cue is edited, it deletes the entire TextTrack and reloads it using Player.removeTrack() and Player.addRemoteTextTrack(). This is also working, except when the new track is loaded with default: true option set, it remains unselected in the player until I click it in the menu.

The documentation is not clear as to how to activate a loaded TextTrack from Javascript, other than setting default: true

I just spent a while stepping through with devtools... it looks like the property that is affected by selecting the text track from the menu is mode, which toggles between 'disabled' and 'showing'

So, if I pass the option mode: 'showing' to addRemoteTextTrack(), it works. The mode parameter in the documentation could use a little touch-up...

...I'm actually seeing the TextTrack.mode constants specified at MDN, now that I know... but I didn't realize it was just standard DOM.

@partap Thanks man.
I followed your way, and finally I could resolve my issue.
But I still can't know why it happens when I use that option.
