Unable to install formulae that depend on ffmpeg when ffmpeg is already installed from this tap about homebrew-ffmpeg

[retokromer]

@JoeNyland This workaround should make it:

brew uninstall ffmpeg
brew install get_iplayer
brew uninstall --ignore-dependencies ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-fdk-aac

Why you not understand? All homebrew receipts are ruby scripts. Don’t maintainers of homebrew does not know how search and replace work? I will not present any suggestion because previously I feel attacked here. But I am not surprised, you don’t even know how to support variants that’s why I switched for the time being to Macports and developing new package manager W dniu pt., 10.11.2023 o 10:51 Werner Robitza ***@***.***> napisał(a):

Do you know if there's any way to do this?

From the top of my head no, but I will try to delve into this during the weekend.

[slhck]

That would mean bundling/maintaining all possible formulas that depend on ffmpeg, which I believe is too much of a maintenance burden.

@Behinder:

1. Asking "Why don't you understand?" is a pointless question and a waste of everyone's time. And for the record, I don't understand what you said either.
2. This project has no official relationship to Homebrew, nor are the folks here Homebrew maintainers.
3. If anyone is attacking here, it's you. Your comments are rude and completely uncalled-for.

[retokromer]

Thank you for reporting. Have you tried to force the installation? Otherwise uninstalling and installing again works fine.

[JoeNyland]

Have you tried to force the installation?

Good idea, but forcing the installation doesn't help.

uninstalling and installing again works fine

I'm aware that this works, but it looks like I'll have to go through this every time that a formula which I have installed depends on ffmpeg (just get_iplayer at the moment) is upgraded. If it was just the once that I had to do it, then I wouldn't be bothered.

If only there were some way that depends_on "ffmpeg" accepted ffmpeg that this tap provides as satisfying the dependency. Do you know if there's any way to do this?

[justinmayer]

If you find a way, I would love to know as well. For my FFmpeg tap, I got the impression my only realistic option was to also "fork" dependent formulae, which I did for both MPD and Chromaprint: https://github.com/justinmayer/homebrew-tap

This is a very cumbersome solution that I would love to avoid, so thanks for looking into this, Reto. I look forward to hearing what you come up with. 👏

[retokromer]

On my end I have added a test on my maintenance script:

if ffmpeg -version 2>&1 | grep "Library not loaded" >/dev/null; then
  echo "[$(date_time)] reinstalling 'FFmpeg'" | tee -a "${LOG_FILE}"
  brew reinstall ffmpeg \
    && echo -e "${BLUE}'FFmpeg' reinstalled.${NC}" \
    || echo -e "\a${RED}Error: 'FFmpeg' not reinstalled.${NC}"
fi

because I was… too lazy to search for a cleaner solution. I will try to figure out if on the formula level it’s possible to resolve this problem.

[retokromer]

@justinmayer Letting you know that I didn’t found yet an elegant solution in the formula.

I ran into this same issue with get_iplayer. In the end, I opted to abandon homebrew for get_iplayer and use its package installer with embedded ffmpeg. get_iplayer doesn't do any encoding itself, so there is no advantage to using a customised ffmpeg. If I ever need the tap version for transcoding I can reference it directly in my post-precessing commands.

However, I also found an alternative using homebrew: Install the core ffmpeg version, pin it (may not be necessary), then unlink it. Rename the formula from this tap, e.g., to ffmpeg-with-options.rb with class name FfmpegWithOptions and a "conflicts_with" directive for the core version, and then install it with the new name. The core version is there to satisfy dependencies, but the tap version is the one linked for use. I used a tap with the new name, but you could also just use a local copy of the formula. No idea if this might cause problems with other formulae.

This worked for get_iplayer, but as to it being a general solution, that would boil down to whether or not you want to change the formula name or set up another tap. I can't think of a reason the tap version of ffmpeg should stomp the core version completely, and the "conflicts_with" directive provides a way to warn users that they need pin and unlink the core version first.

[Behinder]

I have similar problem with pianobar, I updated keg formula on my end for pianobar to reference dependency ffmpeg from tap but after few updates both ffmpeg and pianobar stopped working because
dyld: Library not loaded: /usr/local/opt/openh264/lib/libopenh264.5.dylib is not found.

Homebrew becomes more and more cumbersome to use nowadays

[retokromer]

@Behinder Thank you for reporting! The issue is known: this happens each time when a new version of H.264 or H.265 is released. Did you try to reinstall FFmpeg?

[Behinder]

Yes I did reinstall ffmpeg with all the option from tap repository and pianobar is working now :) Maybe there should be a way to include some post-process script whenever h264/265 is updated.

[retokromer]

Maybe there should be a way to include some post-process script whenever h264/265 is updated.

I actually do it (and many other “things”) with a maintenance script on my end.

The only way I see at the moment would be to bump a revision of the FFmpeg formula each time one of H.264 or H.265 is updated. Yet this would affect all users.

@Behinder Do you have any hint?

[retokromer]

@howyallare Thank you for your input and sorry for my delay!

pin it (may not be necessary),

If I am not completely wrong, pinning has been deprecated and is no longer possible in Homebrew. I remember we did it in the past, but changed at some point.

No idea if this might cause problems with other formulae.

Yes, it does…

[howyallare]

If I am not completely wrong, pinning has been deprecated and is no longer possible in Homebrew. I remember we did it in the past, but changed at some point.

Pinning works fine. You may be thinking of tap-pin. As long as this tap version was installed, upgrades of core ffmpeg were prevented from being linked, so pinning wasn't strictly necessary, anyway.

No idea if this might cause problems with other formulae.

Yes, it does…

Then you're left with the option of publishing another tap formula with a different name. It worked for me, but I'm guessing you already rejected that option at some point, or else we wouldn't be here. It's easy enough for users to do it themselves.

[retokromer]

You may be thinking of tap-pin.

You are right! Sorry for my bad memory.

Then you're left with the option of publishing another tap formula with a different name.

Indeed, this is what we made for a specific purpose.

[JoeNyland]

Thank you @retokromer. That works for me.

[c0494133d4]

How about collect those formulas in this repo? On my local machine I have Taps/homebrew-ffmpeg/homebrew-ffmpeg/Formula/video-compare.rb.

[Behinder]

You can just do simply search and replace script for the user that modify dependencies in each package. W dniu czw., 9.11.2023 o 10:22 Werner Robitza ***@***.***> napisał(a):
