I just downloaded the newest version of Audacity (2.3.0) and am on mac El Capitan 10.11.6.
When I try to open or import an m4a file I get the error message “This version of audacity was not compiled with Quicktime support” and “Audacity attempted to use FFmpeg to import an audio file, but the libraries were not found”.
I’ve read the other posts about this problem, and have opened and closed Audacity, and deleted the 3 .cfg files and reopened. I still get the same message.
Can you help?
Same problem here with AAC, 2.3.0 and Mojave. Was not a problem before with 2.2.2 FFMpeg was installed. Reinstalled the libraries but no change.
Edit: the only thing that is weird is that the FFMPEG library 2.2.2 contains ffmpeg.55.64bit.dylib, ffmpeg_utils.52.64bit.dylib and ffmpeg_codecs.55.64bit.dylib in the suggested lib folder but Audacity says “F(55.33.100),C(55.52.102),U(52.66.100)” for the same folder.
So the problem for me really was that Quicktime is not supported anymore in 2.3.0, is that correct?
Ok it turns out I had 32bit FFMPEG 2.2.2 also installed. Audacity 2.3.0 doesn’t import with FFMPEG, says Quicktime not supported. Audacity 2.2.2 imports with Quicktime. I don’t know how to force FFMPEG for import on 2.2.2 to test further. I deleted the whole audacity application support folder but that didn’t help.
Edit: I want to clarify that I don’t have any issues with FFMPEG export on either 2.3.0 nor with 2.2.2
Edit2: I am now suspecting broken AAC files - testing!
Edit3: Seems to be a FFMPEG 2.2.2 issue with ADTS. FFMPEG 2.2.2 import is otherwise ok. Since Quicktime does not support that file it should default to FFMPEG but that has a problem we get “This version of audacity was not compiled with Quicktime support” error. Shouldn’t an FFMPEG error be shown instead then?
I’m not an expert on macOS (I mostly use Linux), but my understanding is that the QuickTime Library was deprecated by Apple when they launched Sierra, and has been discontinued in xcode (the application for building software for macos).
I suspect you’re right, though I’ve not seen any definitive information about this. The current error message is certainly not helpful, and that is logged on the Audacity bug tracker.
