You can use `org-link-set-parameters' to set a custom handlers for a link
type.

Here is a simple example:

#+begin_src elisp
(org-link-set-parameters "play" :export #'(lambda (path description backend info)
					    (message "path=%s description=%s backend=%s info=%s" path description backend info)
					    (cl-case backend
					      ((beamer latex)
					       (format "\\href{run:%s}{%s}\n" path description))
					      (t
					       (format "")))))
#+end_src

Then, the link

[[play:vlc --rate 3 --loop --fullscreen unfolding.mp4][unfolding.mp4]]

will be exported as a link in the beamer file that runs that command.

For your purposes, with Orm's example,

#+begin_src elisp
(org-link-set-parameters "mp3emb" :export #'(lambda (path description backend _info)
					    (cl-case backend
					      ((beamer latex)
					       (format
                                               "\\includemedia[addresource=%s,flashvars={source=%s&autoPlay=true}]{\\fbox{%s}}{PLAYER}\n"
                                               path path description))
					      (t
					       (format "")))))
#+end_src

should allow you to use a link like

[[mp3emb:music.mp3][Background noise]]

in your Org file.

Note that you do need to set the PLAYER.

Best,
Leo
