ffmpegdecklink: x264 not found using pkg-config

[pjotrek-b]

Hi everyone! 😃

I keep running into the following error brewing ffmpegdecklink on Xubuntu 20.04.6:

ERROR: x264 not found using pkg-config

The current brew-recipe downloads ffmpeg v5.1.2:
(

homebrew-amiaos/ffmpegdecklink.rb

Line 4 in 6909a7a

url "https://ffmpeg.org/releases/ffmpeg-5.1.2.tar.xz"

)

It worked flawlessly on my previous Ubuntu 20.04 setup (ffmpeg v4.4).
I'm guessing it may be related to an issue posted on ffmpeg-user "ffmpeg > 5.0 refuses to build with x264-static"?

I'm currently trying to adjust the brew-recipe with the workaround/fix mentioned in the above post:

• Add --pkg-config-flags="--static" to ./configure

I've never edited brew-recipes before, so it may take a while, but I thought I'd post this here in case someone else also runs into this 😄

Here's the complete and partially cut 😉 commandline and console output:

$ brew install ffmpegdecklink --with-iec61883

@pjotrek-b Thank you for reporting! This should be resolved in #349. Could you possibly test?

[pjotrek-b]

Hi Reto!
Thanks. will test.

btw: I've also tried using the ffmpeg-v4.4 recipe (from git history) - same "libx264 not found" error.
Anyways: I'll test with #349.

Cheers!

@retokromer: Unfortunately, ffmpeg v6 has the same issue:

ERROR: x264 not found using pkg-config
😢

The following codecs are all not found by pkg-config (disabled them one by one in the brew-recipe), until configure is happy and it start to run "make":

--enable-libx264
--enable-libx265
--enable-libxvid

But build fails with quite nasty errors (ffmpeg v5 and v6):

==> make

Is there something like "make clean" for brew?

[pjotrek-b]

btw, here's the output of pkg-config --debug x264:

Is there something like "make clean" for brew?

brew cleanup or even brew cleanup --prune=all

[retokromer]

We also modified the troubleshooting page.

[pjotrek-b]

Thanks for the quick reply! Something is "dirty" in my install - because now the v4.4 build also fails with the same mathops.h errors. Will try cleaning up first 😄

[retokromer]

Try also a brew upgrade before reinstalling ffmpegdecklink.

[pjotrek-b]

Not sure if this is related, but Mozilla devs ran into the "mathops" issue less than a month ago:
https://bugzilla.mozilla.org/show_bug.cgi?id=1846703

And here on FFmpeg's tracker:
https://fftrac-bg.ffmpeg.org/ticket/10405

both seem to conclude:

"It's a change in binutils that has worked its way through."

@retokromer:
Seems you already addressed that patch?
(https://github.com/amiaopensource/homebrew-amiaos/blob/b81dbb4dead96b775cbdd4f31f7f15a47c6d2fc1/ffmpegdecklink.rb)

Disabled x264,x265,xvid - and crossing fingers for successful build!

[retokromer]

@pjotrek-b Please test again with the again patched formula.

[pjotrek-b]

The "x264-x265-xvid not found by pkg-config" issue is still present, but now "make" runs successfully.

[privatezero]

@pjotrek-b, does running pkg-config --print-errors x264 give you any useful output?

[bravoalphatango]

Wanted to add to this thread since the issue was still open. Not sure which patches are being referred to toward the end of this post since a lot had been discussed, but I was running into a similar issue as @pjotrek-b. When trying to reinstall vrecord on my work laptop (M1 Mac running MacOS Monterey 12.6.5) and I was getting the following error:

Seems like whatever the issues were, they were preventing vrecord from compiling. Downloaded ffmpegdecklink.rb and took out “fontconfig” and “x264” from the Ruby source code and told it to disable VulkanOptExtension (since it seems to be for 3D rendering???) and vrecord seems to be working now.

Added

--disable-vulkan

Removed

depends_on "x264"
depends_on "fontconfig"
--enable-libx264
--enable-libfontconfig

I know this is not best practice but it allowed me to continue with brew install ./ffmpegdecklink.rb.

What is strange is that even though I got vrecord to install with the help of @cajunjoel on all our computers (Intel and M1) I am now getting errors on the Intel Mac Mini but NOT the M1 Macbook Pro:

2018 Intel Core i7 Mac Mini running Monterey 12.7.2:

• Deck is not recognized by avfctl command and does not appear on DVRescue tab of vrecord GUI

tothba@SIA-3118AV-1 ~ % avfctl --list_devices

"avfctl -h" for displaying more information.

• Can capture with the following command but not preview window appears during transfer and logs are not created.

avfctl -cmd capture avfctlTest03.dv

2021 M1 MacBook Pro running Moneterey 12.6.5:

• Deck is not recognized by avfctl command and am getting the same error message as the Intel, BUT does appear on DVRescue tab of vrecord GUI and I am able to capture using it.

 ~  avfctl --list_devices

These issues seem similar to what @libbyhopfauf and I were experiencing recently that is explained in more depth here: mipops/dvrescue#760

[libbyhopfauf]

@bravoalphatango this does sound similar to the issue I was experiencing! @dericed can correct me if I am wrong, but I believe that the new DVRescue release will be rolled into vrecord to replace avfctl, so it could possibly resolve this on your end?
