Wrong use of func_get_args()

func_get_args() returns an array containing all the arguments passed to a function, including the ones declared in its parameters list.
A line like if ($args[0] == 'type') $type = $args[1]; (present in kaltura_preview_player()) is simply getting back the same value given to $no_js.

If the function is being called with two different types of parameters, then it would be better to use an empty parameters list, and use just the values given by func_get_args().
