layer slider video not auto play [dexp_layerslider 7.x-1.2]

After upgrading to the latest version:  dexp_layerslider 7.x-1.2,

The Layer Slider video does not seem to autoplay anymore. After some troubleshooting, found some javascript error in sites/all/modules/drupalexp/modules/dexp_layerslider/plugins/rs-plugin/js/jquery.themepunch.revolution.js

On line 3998, the function event.target.getVideoEmbedCode() actually does not exist, therefore breaks the code after that.

Switching that to the older version: event.target.f

Fixed the issue.

 

Please investigate on whether this is the issue with Youtube API itself as getVideoEmbedCode() is Youtube API function or ThemePunch Revolution jQuery module or dexp_layerslider module.

 

Thanks.
