I got that message, but I have already installed both types of libraries onto my computer
HELP!
Please see http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#macff for how to install the FFmpeg libraries.

I have been using Audacity forever and just recently started having the exact same issue. I am running yosemite 10.10.5 and audacity 2.1.1 I have the FFmpeg file in the audacity library folder and audacity will not find the codec I went through all the recommended steps, also I redownloaded the libraries in zip form and also dmg file and attempted to manually find the codec after installing them in different places and even though i find the codec and click on it audacity still says not detected, I haven’t tried working with m4a since upgrading to yosemite until just recently and that seems to be the only change. I can still import m4a but i cannot export. Any help on this issue would be greatly appreciated! Thanks!
The help is in the link already provided Audacity Manual. FFmpeg is usually detected by Audacity on Yosemite and Mavericks without problem, if you follow those steps.
To diagnose any problems we would need to see the log from Help > Show Log… .
You may find it easier to export as WAV or AIFF then convert to M4A in iTunes. See Audacity Manual.

also here is a youtube video of my desktop of me trying to load the file it is about 47 seconds

As it says in the link and on the buanzo download page, you need FFmpeg 2.2.2 for Audacity 2.0.6 or later, not FFmpeg 0.6.2. http://lame3.buanzo.com.ar/ffmpeg-mac-2.2.2.zip or http://lame3.buanzo.com.ar/ffmpeg-mac-2.2.2.dmg.

sorry to be a pain =) but even with the ffmpeg 2.2.2 like i said when i manually try to load the codec it for some reason will not load

In FFmpeg 2.2.2, avutil should be “avutil-52.dylib”, avcodec should be “avcodec-55.dylib” and avformat should be “avformat-55.dylib”. The libav* versions you are loading belong to older FFmpeg.
So it comes down to the same thing, you either have to use only FFmpeg 2.2.2, or export as WAV and convert to M4A in iTunes.
If you want to use FFmpeg, delete all the libav* files that you have now in Applications/Audacity/audacity/.
Then if you believe you had actually downloaded FFmpeg 2.2.2, clear the downloads list or cache in your download manager or web browser and download FFmpeg 2.2.2 again.
