function template_preprocess_jw_player in JW Player 7.2

Same name and namespace in other branches

1. 7 jw_player.module \template_preprocess_jw_player()

Process variables for jw_player.tpl.php.

@todo this whole function seems obsolete. The config passed to jw player should be prepared right where the theme function is called and passed down to js using js settings in #attached within the render array. Along width that, inline snippets in the template should be replaced by a a behavior that initializes the players with the options from js settings.

File

./jw_player.module, line 694

Adds a theme function which allows theme developers to use the JW Player.
