JW Player shortcode in ajax requests

Hello,
when loading WordPress content using AJAX requests the JW Player shortcode is not being replaced at all.

I guess that is because in WordPress all ajax requests are handled by scripts which run as is_admin() === true and the plugin only adds the required shortcode filters when ! is_admin(). See this if block in your code: https://plugins.trac.wordpress.org/browser/jw-player-plugin-for-wordpress/tags/2.1.14/jwp6/jwp6-class-plugin.php#L474

From the WordPress Codex:

Note 2: Both front-end and back-end Ajax requests use admin-ajax.php so is_admin() will always return true in your action handling code. When selectively loading your Ajax script handlers for the front-end and back-end, and using the is_admin() function, your wp_ajax_(action) and wp_ajax_nopriv_(action) hooks MUST be inside the is_admin() === true part.

Best regards,
Alex
