-64 bit Build
-Failed to build: ffmpeg

I do not know if my build is classified as "custom". The only changes I make are in ffmpeg_option.txt:

--disable-everything
--disable-autodetect
--disable-encoders
--disable-decoders
--disable-hwaccels
--disable-muxers
--disable-demuxers
--disable-parsers
--disable-bsfs
--disable-protocols
--disable-filters
--disable-devices
--disable-ffplay
--disable-ffprobe
--disable-schannel
--disable-stripping
--enable-gpl
--enable-version3
--enable-indev=gdigrab
--enable-protocol=file
--enable-filter=scale
--enable-libvpx
--enable-encoder=libvpx_vp8
--enable-encoder=libvpx_vp9
--enable-muxer=matroska
--enable-muxer=webm

I was having no issues building it until I ran the suite yesterday (27th).

Attach C:\MAS\build\logs.zip to the GitHub issue.
Make sure the suite is up-to-date before reporting an issue. It might've been fixed already.

Try running the build again at a later time.

If you're never going to use the locally-generated documentation, just add --disable-doc to your ffmpeg_options.txt and it'll just skip that step entirely.

[hydra3333]

Yes, I did that too :) added --disable-doc to your ffmpeg_options.txt

Also added/modified
--disable-libplacebo in ffmpeg_options.txt
--disable-libjxl in ffmpeg_options.txt
libavif=2 in media-autobuild_suite.ini
jpegxl=2 in media-autobuild_suite.ini
to ignore the currently not-building ones, and then ffmpeg builds a treat for me.

At some stage I'd like to re-include libjxl and libavif and have been playing with them.
However I'm not clever enough to find a fix yet.
I did try to build the latest https://github.com/mm2/Little-CMS instead of using the older pacman version, however that seems to make no difference when building libjxl.
Perhaps I'll look for hints over at https://github.com/BtbN/FFmpeg-Builds and https://github.com/DeadSix27/py-cross and https://github.com/rdp/ffmpeg-windows-build-helpers and https://github.com/Alexpux/MINGW-packages

edit: I also note #2494 (comment) and that I did not need to downgrade pkgconf

An ffmpeg ticket was submitted to ffmpeg trac in case it is something at their end.

Worked for me, thanks!

[hydra3333]

Ah.

Trac ticket https://trac.ffmpeg.org/ticket/10636 had a response:

[comment:2] by Sebastian Ramacher, [6 hours ago]
This is caused by changes in texinfo 7.1 and also affects ffmpeg 6.0 and other releases.

I see (https://www.gnu.org/software/texinfo/ says
The latest official release is Texinfo 7.1 (2023-10-18)

I guess that MABS could somehow install the prior version for the time being ?

[hydra3333]

A kind soul has provided an interim patch which could be used to build the documentation:

Manual is worthy of being kept. I have built this one (https://aur.archlinux.org/packages/ffmpeg-intel-full-git) successfully by adding --disable-htmlpages in PKGBUILD.

ffmpeg build completed successfully for me just now - including the DOCS.

Yes, there's been upstream ffmpeg patches.
