Two other files are included, and they are not accepted by Audacity 2.3.2, after an upgrade. I am on Mojave OS (10.14.5). I tried renaming both files to ffmpeg.55.64bit.dylib, but they still would not load:
-rwxr-xr-x 1 root wheel 379K Feb 28 2017 libmp3lame.dylib*
-rwxr-xr-x 1 root admin 256K Feb 19 07:06 libmp3lame64bit.dylib*
I’ve been a Linux/Mac developer for 35+ years, so I understand files, dynamic libs, etc. I will swear the .zip file did not have the correct files, but it does now. The .pkg definitely did not install them correctly.
Thanks for your help. I wish I understood it, but I guess I must’ve been wrong about the zip.
The link you provided in the third post in this thread provides the proper link to the FAQ in the manual. That FAQ contains a link to the FFmpeg download page, and the 64-bit Mac section of said page.
