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.
