`search' never was advertised as a dynamically scoped variable in
`org-file-apps' docstring, so "org-player" is just playing with fire

I don't like the current solution either (eval with a LEXICAL argument).

I think it would be better to use un function with two arguments (file
and link-string instead). This is not backward compatible, but the
change is trivial: sexp -> (lambda (file link) sexp).

In the current case, you need to use match string:

  (add-to-list 'org-file-apps
               (cons (concat org-player-file-extensions-regexp
                     (lambda (file link)
                       (org-player-play-file file (match-string 1 link)))))
