building with --with-chromaprint problem, recursive dependency on ffmpeg about homebrew-ffmpeg

[walksonair]

Been seeing this as well especially when doing BREW updates/upgrades/doctor...Any way to have a nice FFMPEG update w/o this error?

[retokromer]

Does this

brew uninstall ffmpeg
brew install chromaprint
brew uninstall --ignore-dependencies ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-chromaprint

resolve the issue?

[mcstrassell09]

I am getting the same error "recursive dependency." Hmm. This makes no sense!

Curious, what is that terminal that you are using ?

[retokromer]

chromaprint depends on homebrew-ffmpeg/ffmpeg/ffmpeg

That’s the line in the chromaprint formula:

https://github.com/Homebrew/homebrew-core/blob/2c5fd5b1157cd0dda669255a098acd3e0edba6ed/Formula/chromaprint.rb#L16

[MrBobot]

So it seems chromaprint uses ffmpeg for at least two libraries to do the following, both of which look like it might be possible to remove the ffmpeg dependency.

• FFT
• Resampling

And from the Cmake, it seems we don't need the FFT libraries from ffmpeg and could use Apple's Accelerate framework ?

if(NOT FFT_LIB)
	if(APPLE AND ACCELERATE_LIBRARIES)
		set(FFT_LIB "vdsp")
	elseif(FFMPEG_LIBAVCODEC_FFT_FOUND)
		set(FFT_LIB "avfft")
	elseif(FFTW3_LIBRARIES)
...

Lastly I'm not sure what the resampling library is for, but it would seem that it will still build but with a warning

if(AUDIO_PROCESSOR_LIB STREQUAL "swresample")
    ... 
elseif(AUDIO_PROCESSOR_LIB STREQUAL "avresample")
    ...
else()
    message(STATUS "Building without audio conversion support, please install FFmpeg with libswresample")
endif()

I might give this a go if i have time, never customized a homebrew formula before

[MrBobot]

Ok, its pretty clear that ffmpeg is required for the fpcalc tool as stated on the bottom of the chromaprint page, and for MacOS they actually recommend to use the standard fft libraries.

I wonder if it would be possible to just use the already built chromaprint binary ?

[mcstrassell09]

Curious, what is that terminal that you are using ?

I am using iterm2 with the Molokai Soda colortheme. Default shell is zsh with 0h-my-zsh and iterm shell integration.

I wish i had an answer here. But this is beyond my knowledge scope (novice programmer trying to learn the craft). So I built ffmpeg without the chromaprint option. I am trying to make a manual build of IINA of which ffmpeg is a dependency.

Is it possible to build chromaprint from standard ffmpeg installation, then build an instance of homebrew-ffmpeg/ffmpeg/ffmpeg?

https://github.com/homebrew-ffmpeg/homebrew-ffmpeg/blob/master/README.md

Says will get an error if ffmpeg already installed so I removed before proceeding. This just doesn't seem possible! I would like to know how this was done!

[mcstrassell09]

MrBobot- did you ever get this to work via formula customization? How would I go about building ffmpeg --with-chromaprint with a pre-installed fpcalc library?

[retokromer]

@MrBobot Is this still an issue on your end?

[Rogue-Git-Dev]

Yes, yes this is an issue currently. I too assayed to instal with all options and received the message Chromaprint depends on FFMPEG and FFMPEG depends on Chromaprint thereby making it recursive on itself. I use Mac OS 10.15.6 latest public beta, latest commit of Homebrew, and latest builds of everything – many of which are head builds. To instal without Chromaprint and with all other dependencies is not problematic.

[Rogue-Git-Dev]

Unfortunately not. I tried that as well. Chromaprint is installed as a bottle on my system.

[retokromer]

That’s strange! With mpv – which is also installed as a bottle – it works well. I will test with chromaprint next weekend.

[retokromer]

@Rogue-Git-Dev @MrBobot The workaround should be fine now.

[brianredbeard]

also, FYI, Chromaprint provides a boolean to disable the CLI tools: -DBUILD_TOOLS=off

I noticed that the binary built following @retokromer's commands is not linked to the main ffmpeg command.

After building, if I run the command ffmpeg -muxers I do not see any chromaprint listed.
However, if I run the same command but pointing directly to /usr/local/Cellar/ffmpeg/6.0-with-options_1/bin/ffmpeg -muxers I can see it there.

This, despite brew saying that it should indeed have chromaprint on the normal ffmpeg command:

[retokromer]

@cellulosa What is the output of which -a ffmpeg?

[cellulosa]

mh good point, that points to another build (which isn't a link!). Shouldn't that be overwritten by the new install? Do I need to force brew link or something?

> which -a ffmpeg
/usr/local/bin/ffmpeg
/usr/local/bin/ffmpeg

> ls -la /usr/local/bin | grep ffmpeg
-rwxrwxrwx     1 user  admin  23396536 11 May 09:09 ffmpeg

[retokromer]

> which -a ffmpeg
/usr/local/bin/ffmpeg
/usr/local/bin/ffmpeg

This simply means that you have the same instance of FFmpeg twice in the path, which is not a problem. There is only one.

But then the question is why doesn't this get linked to the formula built with chromaprint?

Instead, it seems it's placing some fresh ffmpeg bin

[retokromer]

@cellulosa I am currently travelling and I cannot reproduce the issue on my laptop. Does

brew unlink chromaprint && brew link chromaprint

have any effect?

[cellulosa]

@retokromer nope, but brew link --overwrite ffmpeg did! Thanks :)

[retokromer]

@cellulosa Thank you for the information.
