How do I "add" the ffmpeg functions toolbox into matlab so that I can use them. This is my code but the ffmpeg part doesn't work.
function transcode(MP3file)
if exist(MP3file, 'file')
ffmpeg -i file.mp3 output.wav;
[y, Fs] = audioread('output.wav');
else
disp('The file doesn't exist')
end
end

Never mind. I figured out how to install it correctly, I followed these steps: http://adaptivesamples.com/how-to-install-ffmpeg-on-windows/ . Thank you!

I don’t have any experience with it myself, but the documentation for Working with Raspberry Pi Camera Board implies that the instructions on install it are at the website:
  • Install FFmpeg to your host computer using the appropriate download links in the ffmpeg.org web site following appropriate installation instructions.

The website doesn't say anything on how to install it, or at least I can't find it.

I looked for a while and I can’t find it either. It has ‘Download’ sites (I have no reason to download it so I didn’t), but nothing that I can find about how to install it or configure it in MATLAB, even in the documentation.
Contact MathWorks and ask them.
I have no experience with Raspberry Pi, and I likely won’t for the foreseeable future. After searching for information on how to install the camera board software and finding nothing, I’m not eager to buy the hardware.

Not familiar with ffmpeg, but maybe try the function call syntax (I assume file.mp3 is a typo and you meant MP3file?):
ffmpeg('-i',MP3file,'output.wav');

"Doesn't work" in what way? Do you get an error message? Incorrect output? Or what?
