Kaltura captions: set default language to None or otherwise force them off?

Question

Using the Kaltura player FlashVars parameter, it's possible to set the default language to English or other languages. We'd like to set it to None, to force captions off, but there does not appear to be a way do this. Are we mistaken?

Here's how to set the language to English as a FlashVar: closedCaptionsOverPlayer.defaultLanguageKey=en

Instead of a value of en, we have tried off, null, none, '', 0, and nothing, but none of those had any apparent effect: captions still appear when the player loads a video.

The test / preview tool related to the use of captions (http://kgit.html5video.org/pulls/421/docs/CaptionsKalturaApi) has no choice for forcing them off, as far as we can see.

Answer 1

1. You can create a player with the cc plugin not loaded.
2. You can the kdpReady notification and send kdp.sendNotification('showHideClosedCaptions'); to hide it.

Answer 2

You have to set in KMC. Click Entry->Captions->Make default, to any file you want. This leads to show the captions which you liked or else nothing appears as caption in player.
