SUMMARY


STEPS TO REPRODUCE
1. Start with a fresh Mac without macports or homebrew installed
2. download digiKam sources --depth 1 --branch 8.4.0
3. cd to ~/digikam/project/bundles/macports
4. run 01-build-macports.sh

EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: 
macOS: 14.6.1 (23G93)
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 5

ADDITIONAL INFORMATION
I'm using Xcode version 15.2.  I can't run anything earlier than 15.0 on this
version of MacOS.  Additionally, this is an arm64, not x86_64 build.

It looks like ffmpeg 6.1.1 is being explicitly used in
digikam/project/bundles/3rdparty/ext_ffmpeg.  I'm going to try 4.5.5 and see
what happens.  Alternatively, it looks like we could specify the flag
"-qt-webengine-ffmpeg", but I'm not sure how to modify the options or
makefiles.

I had to modify a few files to even get this far in the build.  Specifically, I
added the following ports to 01-build-macports.sh:

port install py312-setuptools_scm
port install libass
port install opus-tools
port install libvpx
port install x264
