Skipping parts

[Christilut]

Hi! Thanks for this project, trying to get a build going now.

I'm getting an error on fontconfig, which I assume is part of libass? I don't actually need subtitle support in my ffmpeg build (audio only) so is there a way to skip fontconfig and libass?

Where can I see what other parts can be skipped? I would prefer a build that is as small as possible.

there's not a straight forward way of doing it you'd have to comment out the fontconfig and libass lines from build.sh, and delete the --enable-libass argument from build/build-ffmpeg.sh

Having said that I'm not sure fontconfig is part of the libass build it builds after it so what's the issue with fontconfig, I've done a fast build of fontconfig and that worked (doing a full rebuild to see if that errors)

I'm getting this:

Looks like its picking up an Intel only version of libfreetype from somewhere

from your build directory what does

$ lipo -detailed_info tool/lib/libfreetype.a

give it should show

input file tool/lib/libfreetype.a is not a fat file
Non-fat file: tool/lib/libfreetype.a is architecture: arm64

You didn't set Terminal to run using Rosetta way back when Apple Silicon was new, it was a thing people would do before Brew supported Apple Silicon it can cause issues like this ?

I think you're right, I'm also seeing these warnings:
