ffmpeg 4.3 install errors about homebrew-ffmpeg

[retokromer]

I just ran tests and, considering the remarks made in the ReadMe, the command

brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

works like a charm on macOS 10.15, 10.14 and 10.13 on my end.

[retokromer]

Chiming in a bit late here, but is 10.12 still a version that we would like to support, given that there are now three newer macOS versions, and that it is EOL since November 30, 2019? Also, upstream Homebrew doesn't seem to support it anymore, either.

You are right: neither Apple nor Homebrew do support macOS 10.12 anymore. Therefore I added the label.

[retokromer]

It comes with the following components:

cd /Library/Developer/CommandLineTools/usr/bin
ls

FYI: I just launched the installation on a fresh 10.12.6 machine.

[slhck]

This appears to be an issue with https://github.com/Netflix/vmaf and its build script. See if you can install that manually via the instructions here: https://github.com/Netflix/vmaf/tree/master/libvmaf#prerequisites

[retokromer]

You have probably installed the /usr/local/bin/gcc at some point. Why do you need this version?

The /usr/bin/gcc is installed by xcode-select --install. This is the one I used and, to my knowledge, Homebrew should use this. What is the output of

brew config

[retokromer]

Only indirectly by our formula. It’s actually the x264 formula which is called by our one. See the lines 26–27 in

brew cat x264

or

brew edit x264

Sorry, it’s now 8 in the morning here, and I have to work for my living.

[retokromer]

Sorry for being unclear. I suggested, like @scribblemaniac did, to reinstall the compiler, because on my end the installation has worked yesterday with a similar setting.

Only the clang compiler that comes with the Homebrew installation is needed to run the formula. Any other dependency (including gcc) will be installed via the formula. Please consider also our Remarks and Troubleshooting notes in the ReadMe, because some options need additional steps in a precise order.

[retokromer]

That’s a step forward!

I did explicitly not recommend to use --cc=gcc-10 unless you know exactly what you are doing.

You really have to follow the steps indicated in the Troubleshooting! The FFmpeg installed with chromaprint is the standard one in Homebrew or possibly from MacPorts. You need to remove it again. I’ll no longer repeat what already was said.

[retokromer]

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

works on my end.

[retokromer]

If it works fine, then not.

[retokromer]

To my knowledge, you have not done the second part:

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

[retokromer]

If you wish this version of FFmpeg with chromaprint enabled, then yes. (You can enable also other options as well, when installing.)

[retokromer]

You can do:

brew uninstall --ignore-dependencies ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

(I suppose you resolved also decklink)

[retokromer]

What is the output of which -a ffmpeg?

[retokromer]

The one you just installed should be:

/usr/local/bin/ffmpeg -version

[retokromer]

If you need the other one, you can put this prefix before in the PATH; otherwise why not delete it?

[retokromer]

The system uses the first in the path. That’s what happen when you use

which ffmpeg

When you use

which -a ffmpeg

you print all available instances.

[retokromer]

You could create an alias ffmpeg_new for the new one, and then use ffmpeg and ffmpeg_new as needed.

Yet our formula worked well also on macOS 10.12 and I close the issue.

[retokromer]

I guess the restart is needed for the change to take effect (have forgotten how it is done without restart, have done something like that before with path).

Close and reopen the Terminal should be sufficient.

[retokromer]

@YayNay The icu4c formula has been updated to 67.1 on 2020-05-30 and builds fine on macOS 10.15, 10.14 and 10.13. I will try to test on 10.12 as well, but cannot do it before the weekend.

[selsej]

It is a compile error here, during the make process (for the homebrew-ffmpeg), alright.

I have myself to blame for being careless and aborting the lengthy "svtplay-dl" install (which was going on for really too long) during its install of gcc dependency, as something was probably updated there within the brew packages and simply was left incomplete.

I found no solution to this thus far via brew system, I would be too time consuming to remove the brew altogether and then having to reinstall some of the brew programs (packages) I already have installed.

Have already done that once (about 6 or 7 months ago), and am a bit vary of that.

[retokromer]

Have you already tried:

brew update && brew update
brew upgrade
brew doctor --debug --verbose

[selsej]

Have you already tried:

brew update && brew update
brew upgrade
brew doctor --debug --verbose

Either the brew update or brew upgrade were done automatically when trying to install the homebrew-ffmpeg or the ordinary ffmpeg.

brew doctor --debug --verbose yielded no surprises or errors other than warning about the Xquartz 2.7.7 being outdated; I would prefer to keep that version in order for the ddd debugger to work properly, as it does for the moment.

I can attach the whole output, but this is the part where the warning is issued:

However, I am doing exactly the sequence of commands as you have written them in your previous reply.

Error: You are using macOS 10.12.
We (and Apple) do not provide support for this old version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Discourse, Twitter or IRC. You are responsible for resolving any issues you
experience while you are running this old version.

My highly uneducated guess is that it seems that the gcc got broken (within the brew) when the svtplay-dl install was aborted during the install of the gcc dependency for the svtplay-dl. Which might lead me to guess that you do not need to set up a 10.12 machine, and this error might be specific to my machine, for the above mentioned reason(s).

[retokromer]

it is the exactly the same compile error appearing in ffmpeg or homebrew-ffmpeg make process.

Then it’s not related to this formula.

When you abort a compilation, you can often run a make clean. Why do you not reinstall from source the gcc version you wish/need before installing ffmpeg?

[selsej]

I suspected that, as suggested in my previous replies. But I cannot be sure on this.

When you abort a compilation, you can often run a make clean. Why do you not reinstall from source the gcc version you wish/need before installing ffmpeg?

I did reinstall the gcc, to the newest version, prior to the last attempt of installing the ffmpeg and homebrew-ffmpeg.

While the install of the gcc (10) went fine, the version shown on my system is still 9.0, this could mean that the latest version is still not linked.

I do wonder if it is safe to remove all those header files, as suggested in

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

and how to do that safely.

[selsej]

In addition to all of this, the list of unbrewed files is identical to the one given at:

https://stackoverflow.com/questions/54651403/unexpected-header-files

and I guess that I would might try the suggested solution there first.

I would appreciate any advice on how to remove those (listed) header files safely, or to leave them alone for the time being.

[slhck]

I don't think these unbrewed files are causing any issues related to this problem. So when you run which gcc, where is it pointing to? Indeed you need to make sure that the Homebrew version is linked.

[selsej]

Thanks!!
On question of gcc, when I run

which gcc

the output is

usr/bin/gcc

while the command

gcc --version

shows

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include- 
dir=/usr/include/c++/4.2.1

Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

[retokromer]

Please try also

which -a gcc

(to check if there are not multiple instances).

[selsej]

I wanted to make sure that I am using the homebrew gcc in compiling the homebrew packages, so I run

ln -sf /usr/local/bin/gcc-10 /usr/local/bin/gcc

making a symlink to the homebrew's gcc

However, the attempted

brew upgrade icu4c 

resulted in the same compile errors as earlier.

Regarding your further advice:

which -a gcc 

results in

/usr/local/bin/gcc
/usr/local/bin/gcc
/usr/bin/gcc

while

which gcc 

results in

/usr/local/bin/gcc

[retokromer]

This means that there are two instances of gcc installed. You can check their versions with:

/usr/local/bin/gcc --version
/usr/bin/gcc --version

Usually, in my experience, the easiest on macOS is to use the compiler provided with the latest Xcode version that works for the given macOS version. I cannot remember which one fits for 10.12.6 and would have to check, but you can find this on Apple’s developer website, where you can also download the correct Xcode.

You could also use

brew install --cc=gcc-n.m homebrew-ffmpeg/ffmpeg/ffmpeg

with the correct n and m and, of course, gcc-n.m installed. Yet I do not recommend this unless you know exactly what you are doing!

[selsej]

I did "the test" with the icu4c, which constantly gave the same 3 compile errors with earlier attempts.

It did succeed with install of the latest version of the icu4c (67.0), finally, when the

brew install -cc=gcc-10 icu4c 

was run.

However, when running the

brew info icu4c  

the following appears:

icu4c: stable 67.1 [keg-only]
C/C++ and Java libraries for Unicode and globalization

/usr/local/Cellar/icu4c/67.1 (258 files, 71.7MB)
 Built from source on 2020-07-14 at 16:14:04
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/icu4c.rb
==> Caveats
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:
 echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> /Users/xxxx/.bash_profile
 echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> /Users/xxxx/.bash_profile

For compilers to find icu4c you may need to set:
 export LDFLAGS="-L/usr/local/opt/icu4c/lib"
 export CPPFLAGS="-I/usr/local/opt/icu4c/include"

For pkg-config to find icu4c you may need to set:
 export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

==> Analytics
install: 427,185 (30 days), 1,463,870 (90 days), 3,535,511 (365 days)
install-on-request: 16,939 (30 days), 59,904 (90 days), 113,644 (365 days)
build-error: 0 (30 days)

This, indeed, does not belong to this formulae, but I do wonder if I need to do all of these steps with .bash_profile exports.
The reason is that the icu4c appears in the compile process of the homebrew-ffmpeg.

The last question for now would be - how do I enable all the libraries given in the homebrew-ffmpeg
without issuing them one by one by using the --with option with command:

 brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-fdk-aac --with-.... etc. 

I have seen .x265 and some other libraries listed there and would like them not to be excluded.

MacPorts has the

+nonfree

flag or option for including all the libraries in the install.
Is there any similar option given for the homebrew? (since I would like to have MacPorts (installed yesterday) completely removed from the system). I made a panic install yesterday, since I needed the ffmpeg working urgently.

The Homebrew is my main choice since long ago, and I would like to stick to it and not mix in at all the MacPorts in the system.

Chiming in a bit late here, but is 10.12 still a version that we would like to support, given that there are now three newer macOS versions, and that it is EOL since November 30, 2019? Also, upstream Homebrew doesn't seem to support it anymore, either.

Indeed it looks like the error is No xcodebuild tool and no system framework headers found.

I would rather guess (since xcode and command line tools are installed) that the problem might be as described here, so I am going to look into it:

[retokromer]

Xcode is installed (command line tools as well) on my system.

Then you should NOT experience the

configure: error: No xcodebuild tool and no system framework headers found

error you reported… BTW: the command

xcode-select --install

installs actually the command-line tool, which is sufficient for our purpose.

[selsej]

Xcode and Xcode command line tools were both, of course installed. I stand by that, there was something (a lot) else apparently, "in the background", as it seems.

I am doing the install again of homebrew ffmpeg again, did some work in the meantime, rather unexpectedly.
Did the reinstall attempts several times in the meantime, did some additional brew cleanups, etc.

It turned out that the gdb security certificate was rendered useless on my machine and I had to redo all of that.
I have discovered that when testing the ddd debugger which was installed via brew.

I would warn anyone here in regard to svtplay-dl brew install, which was a mammoth install in terms of time consumption, either do it fully or do not do it at all, I did abort it, did the cleanup and ever since then all sorts of problems have aroused with brew, just for few days now.

The install of rust dependency (1.44) is under way for some time (hours) now, and it is not being ended in error(s) after short period of time, as before.
The compilation process of rust is chewing on some disk space, and I had to cool the machine additionally, since the internal fan started.

I am here at the present moment, for more than few hours now:

==> Installing dependencies for homebrew-ffmpeg/ffmpeg/ffmpeg: rust, gdk-pixbuf, pango, librsvg, libsoxr, libssh, libvidstab, libvmaf, opencore-amr, openh264, libgit2, cargo-c, rav1e, libsamplerate, rubberband, speex, srt, autoconf-archive, leptonica, tesseract, two-lame, wavpack, zeromq and zimg
==> Installing homebrew-ffmpeg/ffmpeg/ffmpeg dependency: rust
==> ./configure --prefix=/usr/local/Cellar/rust/1.44.1_1 --release-channel=stable
==> make

In all earlier attempts, this was a failure step, with 2-3 different compile errors which to me indicated that there was something wrong with either system or the c/c++ compiler, but again, this is just a guess.

Will keep you posted on the progress.

I was hoping that I will spare you the installation process on an additional 10.12.6 machine, since you certainly have other things to do.

I am sorry that I have not succeeded in sparing you from that; I stayed awake for long hours now.... I really did what I could.

My apologies again, for any inconvenience.

This install, as visible from the terminal, is only a first of the listed dependencies - packages to be installed, so we'll see.

Thanks again for your patience and effort.

My intention is to relieve the system from having MacPorts (that I installed yesterday very reluctantly) and Brew at the same time.

[selsej]

It might be important to mention - prior to doing the gdb security certificate procedure, I had to, of course, reinstall the gdb compiler altogether, in order to get the ddd debugger working with c-files (programming).

The rust dependency "make" is ongoing steadily for several hours now.

It seems to me that something really got broken in the c / c++ compiler ever since the ordeal with the svtplay-dl aborted install, when the gcc dependency was under way.
Would hate to have to reinstall the brew altogether, but...

[retokromer]

On my end, I could install the ffmpeg 4.3.1 formula with all options on a Mac mini Server (Late 2012) running macOS 10.12.6. I’m afraid, I cannot reproduce the issue.

No, since i have installed it successfully just a day or so ago.

Here is the output:

which gcc
/usr/local/bin/gcc

and this part is - to me - a bit confusing:

which -a gcc
/usr/local/bin/gcc
/usr/local/bin/gcc
/usr/bin/gcc

Last installed gcc is linked, as it seems:

What do you recommend in this situation, having in mind the output that which -a gcc produces, and these errors with compiling the homebrew-ffmpeg?

[retokromer]

Are the two different? Please check:

/usr/local/bin/gcc --version
/usr/bin/gcc --version

[selsej]

Yes, they are different,

What is confusing to me is that the which -a gcc lists the /usr/local/bin/gcc twice, as shown before.

I believe that everything was fine until aborted install of svtplay-dl, in particular since I aborted this manually during the install of the gcc dependency for that package.

[retokromer]

What is confusing to me is that the which -a gcc lists the /usr/local/bin/gcc twice, as shown before.

Why? This only says that you have twice this value listed in your PATH:

echo $PATH

This doesn’t hurt. If you need an output without double entries, you can use for example:

which -a gcc | sort -u

[selsej]

Thanks again:

The question now is how to proceed with this, to leave the things as they are, or to do perhaps the following:

brew bundle dump --describe --global

and then reinstall the homebrew completely from the list generated by this, given in the ~/.Brewfile

One possibility is to edit out the brew gcc from the list and thus rely on the system provided gcc, as suggested from one of your earlier replies, if I am not mistaken, and to edit out both icu4c and x264 as well from that list.

One attempt to remove the only gcc, by brew gcc uninstall resulted in

Error: Refusing to uninstall /usr/local/Cellar/gcc/10.1.0
because it is required by icu4c and x264, which are currently installed.
You can override this and force removal with:
  brew uninstall --ignore-dependencies gcc

The fact is that the above mentioned compile failures, in the post https://github.com/homebrew-ffmpeg/homebrew-ffmpeg/issues/36#issuecomment-658678146 do remain, as things are now, and point out something with the c/c++ compiler, or simply to the mess in the brew on my machine.

and I can only speculate (if even that) whether the brew gcc reinstall would change anything (I doubt that).

[selsej]

You have probably installed the /usr/local/bin/gcc at some point. Why do you need this version?

As answered before, icu4c and x264 seem to depend on it, but I have suggested in my previous reply that I would want to get rid of the /usr/local/bin/gccanyway.

The /usr/bin/gcc is installed by xcode-select --install. This is the one I used and, to my knowledge, Homebrew should use this. What is the output of

brew config

Well, it is:

[retokromer]

This looks fine.

To my knowledge, icu4c should be keg-only and working fine with clang.

On the contrary, x264 is provided by VideoLAN and needs gcc on macOS ≤ 10.13, because it fails on clang. The formula should install all what is needed, without any external interventions.

[selsej]

On the contrary, x264 is provided by VideoLAN and needs gcc on macOS ≤ 10.13, because it fails on clang. The formula should install all what is needed, without any external interventions.

... meaning that the x264 should be handled by the formula homebrew-ffmpegand thus not need the homebrew version of the gcc, in disregard to the output of the brew uninstall gcc attempt ?

[selsej]

Ok, thanks again, no problem! :)

[scribblemaniac]

and I can only speculate (if even that) whether the brew gcc reinstall would change anything (I doubt that).

brew reinstall gcc is the very first thing you should try in my opinion. You say you interrupted the installation of gcc, then everything stopped working. You probably screwed up the install. Even if you can run basic commands, that doesn’t guarantee that everything was configured correctly. It doesn’t hurt to try this. Force uninstalling gcc will only be a temporary fix, and brew will probably try to reinstall it every time you update something that depends on it or stop you from updating.

This is happening exactly right now - the gcc dependency being installed by the homebrew-ffmpeg install attempt, running right now:
brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

It is taking huge amount (in relative terms) of space, and it is time consuming as well, but I am letting it run.

I have interrupted the install of svtplay-dl during its gcc dependency install, and since then there have been these problems.

Then again, @retokromer suggested that I should remove the brew version of gcc (correct me here if I am wrong), thus I find all of this a bit confusing, but let's see if this gcc dependency install by the homebrew-ffmpeg will do.

This is where it is at the moment:

Here is the portion of the output:

ERROR: chromaprint not found

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

I will look into this asap;

ERROR: chromaprint not found

That’s exactly what is said in the Troubleshooting: you need to install brew install chromaprint before running this formula.

[selsej]

Well, I did hasten with brew install chromaprint now, prior to your answer, without looking at the Troubleshooting section.

Here are the outputs on my system at the moment:

brew ls --versions ffmpeg
ffmpeg 4.3.1

which ffmpeg
/opt/local/bin/ffmpeg
Sejos-MBP:~ sejo$ which -a ffmpeg
/opt/local/bin/ffmpeg
/usr/local/bin/ffmpeg
/usr/local/bin/ffmpeg
/opt/ffmpeg/bin/ffmpeg

[selsej]

Have taken the advice of the @scribblemaniac and @retokromer and am under process of brew reinstall gcc at the moment, after several various attempts and failures in the meantime.

The grave error was not installing the chromaprint prior to the latest homebrew-ffmpeg install, but well, you live, you learn.

[selsej]

Well, I did thing now by the book, reinstalled the gcc, and started again according the homebrew-ffmpeg page with installing prerequisites, and whatever path I take (went so far that I even installed the icu4c with -gcc 10 explicitely), here is what happens with attempt to install chromaprint, which is the first prerequisite:

brew install --cc=gcc-10 chromaprint

The MacPorts version of the ffmpeg is still taking precedence in the system.
Nevertheless:

brew ls --versions ffmpeg
ffmpeg 4.3.1

Should the .bash_profile be updated manually? - taking any advice, thanks.

Also, would like to thank all of you for support and patience. :)

[selsej]

I have already installed chromaprint, prior to installing the homebrew-ffmpeg with options, per command you have listed before.

Here's the output:

brew ls --versions chromaprint
chromaprint 1.5.0_3

Do I need to repeat the whole process again, exactly as you have posted in your last reply?

[selsej]

No, I have not, out of my own insecurity.

Working version of the ffmpeg on my system is still the MacPorts one.
The question I had was how the

brew ls --versions ffmpeg
ffmpeg 4.3.1

takes precedence over the

ffmpeg -version

I did not want to done something hastily again and uninstall ffmpeg without seeing what others have to say.

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

needs still to be done then, I presume?

[selsej]

Previous command was the

brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

Do I need to include the --chromaprint option explicitely, or is it enough with the one above?

Update - doing right now the last two steps as you have instructed.

[selsej]

You can do:

brew uninstall --ignore-dependencies ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

(I suppose you resolved also decklink)

I did both that and chromaprint, as listed in Troubleshooting - Remarks section of the homebrew-ffmpeg page.

I have not done it again prior to these last two commands, so we'll see... The ongoing install seems to have installed the three dependecies prior to installing the ffmpeg with chromaprint as I write this.

[selsej]

So here it is:

brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact) --with-chromaprint

But, since I am lousy at exporting variables to the path, I will have to find the solution to getting this version over the 4.2.3 (that is system-wide).
Not fond of prepending the /usr/local/bin/each time to the command.

I am using ffmpeg frequently, for audio and video. Would like to keep both just to be certain, until I have tested this one.
The intention is indeed to delete the other one (Macports altogether).
This prefix can be then put freely before in the path, I guess...

Thanks, did put the /usr/local/bin/ffmpeg
before the other one in the path.

I guess the restart is needed for the change to take effect (have forgotten how it is done without restart, have done something like that before with path).

Thanks for help and your commitment and patience! :)

Thanks again!
Using the Terminal as we speak (youtube-dl) so I will have to wait until the download is clear... Thought opening the other shell would do, but of course, not.

I guess the restart is needed for the change to take effect (have forgotten how it is done without restart, have done something like that before with path).

Close and reopen the Terminal should be sufficient.

Nope, not even the restart fixed that, but that is well outside of this formula, and the thread is closed.

Many thanks again for your patience and time!! :)
