Audio File in beamer and orgmode

Dear all,

I'm working on a presentation in beamer using
orgmode and couldn´t find information on how to
include an audio file in orgmode to be converted
to beamer and a pdf.

Is there any example that you could share?

Thanks in advance.

Hi Luís,

 it doesn't work OOTB in org-mode, but you can always embed LaTex
verbatim in Org files using the #+LATEX: prefix.

My recommendation: Generate a LaTex file from org beamer with some
blind text at a place where you need your link and then check, what
you have to input there in order to get working links to audio files
by directly rendering from the LaTeX file generated by org.

This page might get you there:

https://tex.stackexchange.com/questions/51632/embedding-sound-files-into-beamer-presentation-with-media9

This part on the page:

\includemedia[
  addresource=igottafever.mp3,
  flashvars={
    source=igottafever.mp3
   &autoPlay=true
  }

has to be marked up in org-mode like this to appear in the latex after
export:

#+LATEX: \includemedia[
#+LATEX:   addresource=igottafever.mp3,
#+LATEX:   flashvars={
#+LATEX:     source=igottafever.mp3
#+LATEX:    &autoPlay=true
#+LATEX:   }

Once it works, this could also be put into an elisp function and
invoked on a keystroke prompting for the url and its name. I think you
can also use #+BEGIN_LATEX: and #+END_LATEX: to avoid repeating the
#+LATEX on every line.

Thank you, Orm. Now I got it to work in LaTex.
Next step will be in org-mode.
Best,
Luís
PS: This example works only with Adobe Acrobat,
but not with Preview on OSX.

Hi Luís,

 I think it'd be good if you post your solution here once you got it
figured out, so other people can benefit from your time spent.

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
