Brew ignores install options

• are reporting a bug others will be able to reproduce and not asking a question. If you're not sure or want to ask a question do so on our Discourse: https://discourse.brew.sh
• ran a brew command and reproduced the problem with multiple formulae? If it's a problem with a single, official formula (not cask) please file this issue at Homebrew/homebrew-core: https://github.com/Homebrew/homebrew-core/issues/new/choose. If it's a brew cask problem please file this issue at https://github.com/Homebrew/homebrew-cask/issues/new/choose. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• ran brew update and can still reproduce the problem?
• ran brew doctor, fixed all issues and can still reproduce the problem?
• ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

I try to install ffmpeg and imagemagic with such options:
$ brew install ffmpeg --with-libass --with-fontconfig
$ brew install imagemagick --with-fontconfig
But I got invalid option: --with-libass and invalid option: --with-fontconfig (see What happened for details).

Seems like brew ignores install options at all:
$ brew options ffmpeg outputs nothing
$ brew options --all outputs nothing

But, for example, /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/ffmpeg.rb contains --enable-libass.

Usage: brew install [options] formula
Install formula.
formula is usually the name of the formula to install, but it can be specified

in several different ways.
Unless HOMEBREW_NO_INSTALL_CLEANUP is set, brew cleanup will be run for the installed formulae or, every 30 days, for all formulae.
-d, --debug                      If brewing fails, open an interactive
                                 debugging session with access to IRB or a
                                 shell inside the temporary build directory
    --env                        If std is passed, use the standard build
                                 environment instead of superenv.If super
                                 is passed, use superenv even if the formula
                                 specifies the standard build environment.
    --ignore-dependencies        Skip installing any dependencies of any
                                 kind. If they are not already present, the
                                 formula will probably fail to install.
    --only-dependencies          Install the dependencies with specified
                                 options but do not install the specified
                                 formula.
    --cc                         Attempt to compile using provided
                                 compiler. compiler should be the name
                                 of the compiler's executable, for instance
                                 gcc-7 for GCC 7. In order to use LLVM's
                                 clang, use llvm_clang. To specify the
                                 Apple-provided clang, use clang. This
                                 parameter will only accept compilers that
                                 are provided by Homebrew or bundled with
                                 macOS. Please do not file issues if you
                                 encounter errors while using this flag.
-s, --build-from-source          Compile the specified formula from source
                                 even if a bottle is provided. Dependencies
                                 will still be installed from bottles if
                                 they are available.
    --force-bottle               Install from a bottle if it exists for the
                                 current or newest version of macOS, even if
                                 it would not normally be used for
                                 installation.
    --include-test               Install testing dependencies required to
                                 run brew test.
    --devel                      If formula defines it, install the
                                 development version.
    --HEAD                       If formula defines it, install the HEAD
                                 version, aka. master, trunk, unstable.
    --fetch-HEAD                 Fetch the upstream repository to detect if

                                 outdated. Otherwise, the repository's HEAD
                                 will be checked for updates when a new
                                 stable or development version has been

Error: invalid option: --with-libass

What you expected to happen

I want ffmpeg to be installed with libass support

Step-by-step reproduction instructions (by running brew commands)

$ brew install ffmpeg --with-libass

[MikeMcQuaid]

Homebrew/homebrew-core formulae no longer have install options. ffmpeg uses libass by default now.

[artemmukhin]

@MikeMcQuaid thanks for the quick response!

Could you please tell me what should I do to use rgb24 with gif format? My ffmpeg outputs Incompatible pixel format 'rgb24' for codec 'gif', auto-selecting format 'rgb8'. I also tried installing gifsicle, got it still doesn't work.

[MikeMcQuaid]

Sorry, I'm not familiar enough with ffmpeg to help.

[slawiko]

But for example this page: https://formulae.brew.sh/formula/libav has list of options. Is it a mistake, or there is possibility to install formulae with options? If it exists - please provide some information

[vitorgalvao]

there is possibility to install formulae with options?

Options aren’t deprecated, they just don’t exist in the core tap anymore. They are still supported and encouraged in third-party taps.

[artemmukhin]

Seems like this tap can help to install ffmpeg with options.
