Audacity 3.2 for Mac Silicon does not find homebrew-installed ffmpeg

[M-D-M]

Bug description

Summary:

Wanted to use the new version of Audacity for Mac Silicon (thanks for making it!), but unfortunately it does not find the version of ffmpeg I have installed through homebrew.

Further Description:

Installed Mac Silicon version of Audacity via .dmg file. Selected "do not replace previous version" when prompted via MacOS, because I wanted to keep the previous x86 version handy.

When loading Audacity, it says that ffmpeg libraries aren't loaded, and when trying to direct it to the folder with ffmpeg libraries installed via Homebrew (/opt/homebrew/Cellar/ffmpeg/*/lib), it does not find the right library.

Steps to reproduce

Download Mac Silicon version of Audacity.

Install using dmg file, and select "do not replace previous version" when prompted via MacOS.

Open Audacity, and get the popup about ffmpeg libraries not found.

Expected behavior

Audacity finds the ffmpeg libraries.

Actual behavior

Audacity is saying that "ffmpeg library not found."

Audacity Version

current master / alpha / nightly build

Operating system

macOS

Additional context

I have ffmpeg installed and in my path via Homebrew -- confirmed with "ffmpeg -version" from a cli.

It looks like audacity is wanting a file named "ffmpeg.64bit.dylib", but the files in the ffmpeg folder have names like the following:

libavcodec.59.37.100.dylib
libavdevice.59.7.100.dylib
libavfilter.8.44.100.dylib
libavformat.59.27.100.dylib

@M-D-M we will look into it, but for now please download and install the FFmpeg package for OS X from Buanzo's website. Once it's installed, Audacity should recognize it automatically.

Verified. I don't see the original issue anymore. Now Audacity recognizes FFmpeg installed by Homebrew.

Thank you for looking into this so quickly!

Following up on the ffmpeg package from Buanzo's website -- I already had the x86 libs installed, but could not find any arm libs.

Was this the key line that solves the issue?

paths.emplace_back(wxT("/opt/homebrew/lib"));

FYI: I tried opening up Audacity for Mac Silicon again, and manually entered this location ("/opt/homebrew/lib") into the preferences, and now the ffmpeg libs are correctly found:

I already had the x86 libs installed, but could not find any arm libs.

AFAIK, there's one .dmg package for both architectures.

(I think the buanzo website was updated after this issue was made)
