homebrew options for ffmpeg in readme deprecated

[gennaios]

Hello,

Many of the options for ffmpeg install via homebrew have been removed, such as --with-fdk-aac.

Homebrew/homebrew-core#36938

As such, with a default install, I get the message:

Your ffmpeg version cannot produce top quality aac using encoder aac instead of libfdk_aac

A very sad decision from homebrew team. The easiest option now is to use a fork with brew options https://github.com/varenc/homebrew-ffmpeg

I'll take a look into this in the next days. Thanks for reporting...

[gennaios]

Thank you. I tried that fork a few days ago but am trying again now. I think the only options available with it are --with-chromaprint and --with-fdk-aac. I'm trying --HEAD to see mainly to figure out how to properly get --no-conversion to work.

brew tap varenc/ffmpeg
brew tap-pin varenc/ffmpeg
brew uninstall ffmpeg
brew install --with-chromaprint --with-fdk-aac

The rest of options are enabled by default now.

[gennaios]

Those are the options I used. Thank you.

Man, this was tough... i did not manage to find an easy solution for this, so i had to update the documentation with more commands i'd like to.

It seems that there is or once was a formula of m4b-tool in the core brew repo, which confused my brew installation and he always tried to install v.0.3.1, which is not the latest one and crashed with wrong checksums... very strange.

Furthermore, there is no handy command to install ffmpeg with libfdk besides the varenc repo. I hope i did not miss something, but if someone knows a better / shorter approach, i would appreciate it.

Looks good to me. FYI, I have noticed that m4b-tool when using ffmpeg without fdk-aac (yeah, that message about missing lib is really hard to notice, and homebrew silently dropped options, so it installed vanilla ffmpeg instead of pre-configured version), all m4b parts were converted correctly, but then it failed to merge them (e.g. the result was 5kb file without any sound).

Should it, maybe, fail by default without fdk-aac, and add a param like --ignore-missing-fdk-aac for those who are willingly trying to screw themselves?

@kpumuk
Would you mind adding an extra issue for this? I need the exact circumstances, command line params and error messages, so that i can reproduce and fix the issue...

Hello,

Looks like the tap mentioned in the README is no longer maintained. The new repo is

https://github.com/homebrew-ffmpeg/homebrew-ffmpeg

Ok, I'll take a look in the next days.
