• [ YES ] Ran brew update and retried your prior step?
• [ YES ] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [ How do I confirm this distinction? It appears to me this is an issue specific to brew ffmpeg ] Confirmed this is problem with specific formulae and not Homebrew/brew? If it's a general Homebrew/brew problem please file this issue at https://github.com/Homebrew/brew/issues/new

I'm not sure what to do with this section, but please let me know how I can help.

The option was dropped in HEAD because they now have their own internal version:

- add internal ebur128 library, remove external libebur128 dependency

So just don't use that option :)

[mixelpixel]

@ilovezfs thank you. For future installs - how would I find that kind of information?

[ilovezfs]

brew install -i --HEAD ffmpeg
./configure --help
grep -r ebur .

[mixelpixel]

@ilovezfs Thank you :)

What does -i do? Is it a flag for interactive, ignore or something? I don't see any information on that flag in brew install -h and I am not sure how to read this from man brew

   HOMEBREW_DEBUG_INSTALL
          When brew install -d or brew install -i drops into a shell, HOMEBREW_DEBUG_INSTALL will be set to the name of the formula being brewed.

   HOMEBREW_DEBUG_PREFIX
          When  brew  install  -d  or brew install -i drops into a shell, HOMEBREW_DEBUG_PREFIX will be set to the target prefix in the Cellar of the formula
          being brewed.

[ilovezfs]

Yep it's the same as --interactive just as -d is the same as --debug

[mixelpixel]

@ilovezfs thanks again - apologies for the rudimentary questions. Similarly tho - how does one go about finding this out when the man pages don't specify accordingly? (I have a lot to learn, but I am trying!)

https://github.com/Homebrew/brew/blob/master/Library/Homebrew/extend/ARGV.rb

The ones that use flag? also respond to -thefirstletter as a shorthand

[mixelpixel]

@ilovezfs thank you very much!

[ilovezfs]

You're welcome!
