Error when installing ffmpeg on Mac using avpres.net instructional

[eliseschierbeek]

I'm attempting to install FFmpeg on Mac OS Big Sur 11.7.1 using the avpres.net instructions for Mac (linked from FFmprovisor). I am using the following commands:

brew tap avpres/formulae
brew install --with-openjpeg --with-rubberband --with-svt-av1 --with-tesseract avpres/formulae/ffmpeg

I'm receiving back:

--enable-libtesseract

ERROR: libmp3lame >= 3.98.3 not found

The install worked on my home computer, but not my office machine. I was able to install the avpres formulae FFmpeg using brew install ffmpeg.

Thank you for reporting! The issue should be filed at the formula’s repository rather than here.

Two questions:

• On which system did you get the error message?
• What is the output of lame --version?

Thanks for your response!

The error showed up on Mac OS Big Sur 11.7.1 (work computer). To clarify, I was able to install FFmpeg using brew install ffmpeg on that same work computer.

The output of lame --version is -bash: lame: command not found

Then I guess brew install lame before using the formula should resolve the issue.

It’s strange: usually the FFmpeg compilation tests that. But I will check if the formula should be amended, in order to avoid this error message. Thanks again for reporting.

@eliseschierbeek Could the issue be solved?

brew install lame solved the issue
