On Mac, installed FFmpeg 4.4.4, Audacity still doesn't accept M4A (AAC) file

Audacity 3 Help Forum macOS
1

I see that others have posted about the same problem on Windows, but I have not seen posts about this on Mac.

I have FFmpeg 4.4.4 successfully installed under Mac OS 10.14.6. (I need other software that requires no higher than Mojave.)

But Audacity still refuses to open or accept a .m4a file, with the message “[filename] is an Advanced Audio Coding file. / Without the optional FFmpeg library, Audacity 3.4.0 cannot open this type of file.”

Help? Thanks!

Judging by the log you have FFmpeg 5 installed. This package is incompatible with 10.14

Thank you !
So, i have 1 questions :

  • is Audacity 3.2.2 compatible with Mojave ?
  • As documentation is sometimes confusing, could you tell me how to dowload and install the right Mojave compatible ffmpeg version ?
5

Any version of Audacity is compatible with Mojave, however it is recommended to download Intel version for older macOS versions.

For FFmpeg you can use ffmpeg_64bit_osx.pkg from https://lame.buanzo.org/

I tried using ffmpeg_64bit_osx.pkg, but now Audacity doesn’t find ffmpeg.64bit.dylib, as it is not inside /Library/Application Support/audacity/libs.
I’m trying now using brew…
So hard !

I had to go back to Audacity 2.0.6 as it seems to be the only compatible version with Mojave.
Everything is Ok now.
Thanks
